DIY pipe bender with dimensions. How to make a simple pipe bender with your own hands - available options. Electric machines for bending profile pipes

Owners country houses or personal plots during pipeline renewal or any construction work, robots are often faced with the need to bend a round or profile pipe at a certain angle.

If such a process has to be carried out frequently, it is better to purchase special equipment. But if such a need arises rarely, then you can make pipe benders for a round pipe with your own hands using simple manipulations; video lessons and drawings of this design will be presented in the article below.

In this publication we will talk about how to make a pipe bender at home from improvised means for bending round and profile pipes. However, before starting the description step-by-step production, in the introductory part, let's look at what this tool is and for what purposes it is used on the farm.

What is a pipe bender and what is it for?

It is a design that makes it possible to bend profile or round pipe materials at the desired angle. They are divided into:

- hydraulic;

- mechanical;

- manual.

The first type copes with bending large sizes, mechanical models are used for medium-sized ones, and manual ones are considered ideal option for diameters up to 3 cm and profiles up to 4 cm.

According to their own design features, functionality and operating principle they are divided into:

- crossbow;

- segmental;

- spring.

The operating technology of any pipe bender is the ability to correctly bend the product to the required radius. If no attention is paid when bending Special attention quality of the result, then homemade structures will cope with this task 100%.

Made from a metal pipe and nut

This type of bending device is considered the most elementary. It is made from a piece of rigid round pipe (metal rod) with a nut attached at the base.

For the tool to work effectively, the following characteristics must be adhered to:

select the nut so that its size internal thread was at least 30% larger than the diameter of the bent sample;
the handle itself should be as hard as possible so as not to deform under pressure. It is advisable to use a steel rod.

This tool is very easy to use. One person can perform the bending independently (without assistants). Regardless of the fact that the design is quite simple, it can do its job direct assignment with pipes up to 3 cm in diameter.

To carry out the procedure, you will need to complete the following steps:

We make a template for the future bend from wire;
We take measurements of the template and transfer them to the pipe;
The pipe is installed on a flat floor with a hard surface;
The pipe is inserted into the pipe bender nut, comparing its direction with the measurements on the pipe;
With your foot, resting on the pipe that is on the floor, we press it harder, and bend the second edge, slowly pulling the handle of the pipe bender towards you. Such manipulations allow it to be bent by 10˚.
Moving the pipe along the hole of the nut, the procedure is repeated several times until the bend eventually takes the desired shape.

Wood pipe bender

To bend a round pipe yourself, you can make a pipe bender from wood with your own hands. From a technical point of view, such a device is the simplest; it does not require additional details, such as a hydraulic cylinder.

We start by knocking together several boards of dense wood and cutting out half a circle of the appropriate diameter. For cutting, you can use the simplest hand saw, the main thing is to ensure that the slope is maintained closer to the base.

The resulting workpiece is attached to a solid base in the form of a tabletop or wall. An additional block of wood is also attached to the base to create additional support.

When choosing a tree, pay attention to the fact that its thickness must be greater than the diameter of the pipe, otherwise during the process of bending the sample, it may slip and cause injury.

To easily make a wooden pipe bender for a round pipe with your own hands, you can familiarize yourself with the video lessons below. This will help you understand all the nuances of this process.

How to work with it?

We place the pipe in the recess between the wooden semicircle and the thrust block and carefully begin to press on it from the back side, bending it to the desired shape.

The main thing is that it fits easily into the opening. Given wooden device bends aluminum and steel products well. Moreover, its production requires minimal costs.

Pipe bender made of metal hooks

To make it you will need to carry out the following simple steps:

buy at any hardware store hooks made of high quality metal;
we fasten them on a stable base in increments of no more than 5 cm. However, the distance of one hook from the other will depend on the size of the product that needs to be bent;
as a result we get a semicircular template;
An additional stop is attached to one side of the device.

The bending process will resemble working with a wooden template, but in this case it is not worth it different diameters To make a new template, simply move the distance between the hooks.

It consists of rollers and a cylinder and is a more complex unit. But it allows bending at any angle up to 360˚. In fact, it is possible to create a pipe bender for a profile pipe with your own hands, as similar as possible to technical specifications, for hydraulic equipment.

The sample is fixed using rollers, and a freely moving cylinder gently bends it to the desired angle. To make such a unit with your own hands you will need:

two steel plates 30 cm long and no more than 10 millimeters thick;
four steel corners with shelves measuring 5x5 cm;
from wooden planks the template is knocked down, the thickness of which should not exceed 3 cm;
the steel plate is attached to the underside of the wooden template;
on the base, in order to give greater strength to the structure, it is advisable to attach corners;
a second steel plate is attached to the top;
in the latter a hole is made of the same diameter as the screw that will be installed there;
the bolt serves as a support for the bent pipe;
Angles and rollers are attached to the top plate, which are oriented inside the pipe bender;

This type of design makes it possible to bend any profile product at any angle.

Rules for using homemade manual pipe benders

In order for the manufactured device to perform its job efficiently and correctly, you need to adhere to several simple rules for its use:

If seam pipes are offered for bending, which are used when installing a pipeline, then the seam should be placed towards the bend;
In the case of bending large diameters, it is recommended to work with a partner;
During the process, use protective equipment and do not forget to adhere to safety regulations.

Summarizing all the above information, we can say one thing: building a pipe bender yourself is a feasible task. And you can bring it to life with a minimum amount of free time and money.

This article describes step-by-step techniques for creating pipe benders of varying complexity for working with standard round and profile pipes. The materials that will be required to create structures with your own hands with minimal financial expenses are described in detail.

Choice a certain model directly depends on the size of the workpiece and on the availability of available tools necessary to create a particular design. The presented photographs and video materials will help you understand all the nuances of this topic and make everything yourself!

The need to bend pipes often arises during the construction of arched polycarbonate greenhouses, canopies and canopies, as well as during installation heating systems, hot and cold water supply. Firms that carry out these types of construction work at a commercial level purchase special machines produced at the plant. They pay for themselves even with constant intensive use.

In 2019, non-professionals prefer a profile pipe bender made independently, using materials at hand and suitable auto parts. Devices of varying levels of complexity make it possible to bend products at the required angle in full accordance with the designated degree measure. By doing this, there is a chance of avoiding breakdowns, various types of deformations and defects.

What is a pipe bender?

A pipe bender is a technical device that refers to units, tools and mechanisms intended for processing metal products.

Using it, you can easily and carefully bend a profile or regular pipe along the specified radius. This product is used for the installation of heating systems, hot and cold water supply, as well as for the construction of various frames and structural components of rather intricate shapes, often used in the construction process.

The most common example is a greenhouse on a country plot and the installation of a covered veranda in a private building.

Kinds

Despite the outward appearance of ease and simplicity of the operating principle itself, there are a large variety of designs and types of pipe benders. According to their main characteristics, they are divided into certain conditional categories.

Based on the type of drive, these machines can be divided into:

Electromechanical pipe benders how the drive is used by stepper or ordinary electric motors. The latter are connected using a reduction gear, which allows the applied forces to be stretched over time and to achieve the highest quality bending of the product.

Hydraulic pipe benders They are a more advanced version of a conventional manually driven rolling mechanism. Using a hydraulic cylinder as a pressing device significantly reduces the effort required to operate the device. It can be controlled either manually or using a mechanism.

Manual pipe benders rolling type are considered the most popular machines that are present in the workshop of every owner.

According to the method of bending products, the most correct division would be:

Mandrel pipe bender, usually manufactured at a factory, often using a hydraulic or electromechanical drive. The main advantage of this device is the high-quality bending of profiles with a small radius of curvature.

This can be achieved by previously introducing a rod into the processed part of the product, which consists of a certain number of calibration elements, in dimensions virtually identical to the internal cross-section of the pipe and connected to each other using hinges. (During the bending operation, such elements “hold” the profile walls inside, preventing them from crumpling and failing. The bending process is carried out during one cycle).

Segmental pipe bender used for processing pipes with thin walls made of soft metals. The vast majority are in constant use by plumbers and heating specialists. It looks like 2 levers that are connected to each other by hinges and are equipped with special holders for pipes.

Where the hinge joint is located, a mandrel with the required curvature radius is installed.

The handles of the tool are spread as wide as possible, the ends of the bent product are placed in holders, and the middle is placed on the mandrel. Bending is carried out by bringing together the handles (more expensive models will be equipped with a certain number of changing or regularly fixed mandrels).

Spring pipe bender intended for the purpose of giving the required shape to the components of air-conditioned systems with thin walls. In fact, it is a spring of a specific diameter that is empty inside, in the middle of which the part to be bent is placed. To get a good bend, you need to have extensive experience in operating this type of device.

Crossbow pipe bender used for processing thin-walled products made of aluminum, copper and steel. It is a T-shaped frame, on the top crossbar of which holders for the product are fixed, and in the center, parallel to the long crossbar, a movable lever is installed, which is equipped with interchangeable mandrels. The lever is extended by pressing the handle of the device. The ratchet mechanism makes it possible to slowly increase bending forces.

How to make a pipe bender for a profile pipe with your own hands

In order to save money, the device for bending profile pipes is made by hand. After all, the difference between purchasing a pipe bender and having one homemade creation is approximately 35,000 rubles, since the material for the device can be found at points where ferrous metals are purchased.

The appearance of a homemade pipe bender, naturally, will be inferior to a store-bought one, but it can handle the functions assigned to it quite effectively.

Using a similar tool, you can make with your own hands both a regular canopy and structures that are much more complex in design, for example, a polycarbonate greenhouse, an enclosure for penning and keeping pets, etc., in fact, any where they use a profile pipe bent under required radius.

Step-by-step instruction

Method 1 is characterized by a fairly simple and economical process:

A wooden hemisphere is made.
Several boards are found and using a hacksaw, template hemispheres of the required diameter are cut into them. Experts recommend doing this in such a way that the slope is directed towards the base.
The cut boards are secured to a strong, stable tabletop. It is worth considering that these boards should be chosen thicker than the product itself - in the future the pipe will not jump out of the structure and will not cause harm to the limbs.
A beam is attached to one side of the hemisphere, serving as a stop. The pipe itself should be located in the middle of the stop and the wooden matrix.

Method 2 is simple and inexpensive. It will require strong iron hooks:

The hooks are attached to the base so that the distance between them is approximately 5 cm (in general, this does not play a significant role - it has important only the material that needs to be bent). The result should be a circle of the correct shape.
Then, you need to mount the stop from the edge of the structure. This method is extremely suitable in that it makes it possible to bend products of a wide variety of diameters.
If you change the distance between the hooks, you will be able to bend pipes of completely different diameters.

Method 3 makes it possible to create this pipe bender yourself, which could bend the pipe 360 degrees:

As usual, you will need a pre-prepared wooden matrix. A steel plate is attached to the bottom.
A second plate is fixed on top, in which a hole must be made (the diameter should be approximately equal to the diameter of the screw fixed here).
Corners and fixing rollers directed inward are attached to the upper part. This design can change the angle of pipes of virtually any diameter.

Diagram of a pipe bender for a profile pipe

DIY rolling machine for bending profile pipes

The most primitive rolling pipe bender is being built with my own hands, using the above drawing. The three-roller device uses duralumin sheets 3 mm thick as a housing. General markings are applied to them using a regular pencil. Places for landing the rollers are arranged using a hand or electric drill. Good rollers come out of rope pulleys with bearings. On the opposite side of the roller, which forms the vertex of an isosceles triangle, a high nut is welded, which serves as an element of the clamping mechanism.

The force is transmitted from the clamping screw through a U-shaped element with built-in holes for the screw and roller fastening. The washer welded to the hole for the coil is responsible for ensuring that the pressure roller rises.

Although the prepared pipe bender does not have a winch mechanism for rolling pipes, which would significantly complicate the device, ensuring bent profile construction work small greenhouse will become simple and convenient.

Purchasing a pipe bender does not justify the investment in it at all, because the need to use it will only arise once. In this case, it would be optimal to create such a device with your own hands, or to bend the necessary pipe yourself. To do this, you can use welding or a grinder, or heat the metal until it turns red.
A homemade hydraulic pipe bender for a profile pipe can be improved by attaching an engine to its mechanism, which is equipped with a gear motor that drives the rollers through a chain drive. A device with a car jack, which is installed in place of the upper roller, can work with pipes of various diameters. The jack itself makes it possible to adjust the level of pressure on the pipe section, as well as set the desired height. If you attach both an engine and a jack, this will significantly expand the range of work on bending profile pipes and provide a choice of how to achieve the final result for its owner.
It is necessary to ensure that the alignment of the bearings is within acceptable limits- the distortion will prevent the installation of the shaft.
It's important not to forget that depending on the diameter, the rotation speed of the drill and the pressure force depend.

A do-it-yourself pipe bender is an extremely simple and primitive thing, but for personal non-commercial use it is quite possible to bend medium-diameter profile pipes with such a device. Moreover, it can be improved: removable rollers are attached or holes are made for larger rollers.

The only significant disadvantage of such a device is the absence of a handle, which significantly simplified the task due to the increase in the shoulder. But everyone can eliminate this drawback individually with their own hands at home, but only when the skill of using a conventional pipe bender has been sufficiently mastered.

To work with pipes or angles, a special machine called a pipe bender is required. This design allows you to bend metal elements at a given angle. If necessary, you can make a professional pipe bender with your own hands, which is used in a wide variety of industries. Unlike the industrial version, a homemade pipe bender is much cheaper. When carrying out the work, you can use available materials, which will greatly reduce the cost of the structure. Let's take a closer look at how to make a pipe bender with your own hands at home.

Pipe bender device

There is just a huge amount various types the device in question. Before creating it yourself, you should develop a drawing of a pipe bender or download it on the Internet.

You can make a pipe bender for a round pipe with your own hands, taking into account the following features of its design:

Run-in. This type of pipe bending machine is characterized by the fact that one end of the workpiece is fixed, and a stationary template is used for bending. Running in is carried out using pressure rollers. This manual pipe bender design has been used for many years.
Winding. Special pipe bender for aluminum pipes characterized by the fact that the workpiece is pressed against a movable template, which is used as a roller. The broaching is carried out between the roller in motion and a special stop. As a rule, the drive is electric, since the required force is quite high.
Crossbow design. This scheme is represented by a combination of two fixed rollers, as well as a movable template. The force is transmitted to the workpiece through a movable template, which is located between two rollers. By controlling the movement of the moving element, the most suitable bending angle is selected. It is worth considering that the pipe bender punch, which acts as a template, can have a different shape.
Rolling or rolling. In this case, the scheme is represented by a device with three rollers, two of which are supporting and one is movable. The bending radius is adjusted by changing the position of the central roller. It is worth considering that such a device is considered universal, since the bending radius can be adjusted over a fairly large range. The dimensions of this type of pipe bender are relatively small; a homemade design can be compact.

Choosing the most suitable design for homemade, it should be taken into account that the version operating on the knurling principle is often produced industrially due to the high complexity of the main mechanisms. The crossbow bending method is used extremely rarely today, as it has one significant drawback: the pressure is concentrated on the upper part of the template. When using a crossbow machine, there is a possibility of a significant reduction in the thickness of the pipe wall, as well as its rupture. It is not recommended to use such a device for bending thin-walled workpieces.

The most widespread design is one that operates on the rolling principle. It is practically devoid of all the above disadvantages, has a relatively small size, can be portable, and has the ability to adjust the bending angle.

A homemade machine can have the most different design. When choosing a type, attention is paid to what radius should be obtained. The most important parameters of the workpiece, which can influence the choice of a suitable design, are the thickness of the pipe walls and its diametrical size.

Types of pipe benders

The design under consideration can be classified according to a fairly large number of characteristics. There are universal versions on sale, as well as for narrowly targeted applications. The device differs in the following ways:

By drive type. An important element designs can be called a drive, which can be hydraulic, electric, manual or electro-hydraulic. Recently, the electric drive has become more widespread, as it is compact and very efficient. Hydraulic is more efficient, but it is difficult to operate, takes up a lot of free space and requires periodic maintenance. A manual pipe bender is distinguished by the presence of a mechanism that significantly increases the applied force. If we consider homemade options, then they make a manual pipe bender with their own hands. In addition, you can create your own pipe bender by hand with electric drive. But it’s almost impossible to make a hydraulic version yourself.
Classification is also carried out according to the degree of mobility. There are stationary and portable design options. In most cases, a universal manual pipe bender is designed as a portable structure. A homemade pipe bender for a round pipe can be attached to the base in various ways. It is worth considering that during the execution of work, part of the resulting stress is transferred precisely to the base. Therefore, when creating homemade version execution, it is necessary to ensure reliable fixation of the device.
According to the method of influence on the workpiece - the main sign of classification. For example, a crossbow-type pipe bender has its own special design, which is suitable for bending metal or metal-plastic pipes. In addition, there is a design that works on the principle of running, winding or rolling.

A homemade pipe bender for metal-plastic pipes can be the most various types, but most often they create a mechanical type, when due to a special design the transmitted force increases several times.

Instructions for making a pipe bender

Recently, the question of how to make a pipe bender with your own hands has become quite widespread. Such equipment is required during setup production activities of the most varied types. The simplest do-it-yourself pipe bender has a template type of design. This is due to the fact that it is quite difficult to make rollers for a pipe bender with your own hands.

Considering the template pipe benders for round pipes, we note the following points:

In the manufacture of structures, solid wood is often used. This greatly simplifies work and reduces costs. However, it is worth considering that the low strength and rigidity of wood determines the use of such a machine only for bending aluminum, which has high ductility.
Applicable wooden block must have dimensions that are larger than the diameter of the workpiece being processed.
The template must have a radius that matches the bending radius. In order to simplify the process, a small groove is created in the central part of the surface that is in contact with the workpiece.
For ease of operation, two handles are created, which have a metal fastening.
Having created a pipe bender at home, it should be attached to a solid base, and a stop should be installed on the reverse side.

An important point is that the design in question is applicable to a greater extent for large-diameter bending. In addition, a shoe for a pipe bender of this type is not required; the load is distributed evenly, which allows processing of thin-walled workpieces.

You can make a pipe bender with your own hands according to other drawings. Before choosing the most suitable design, you should consider how often the work will be carried out, for what type of workpiece the machine is made, and how mass production will be. The template type design is characterized by quite large sizes, however, to manufacture it, it is enough to carry out carpentry work; the materials used are low cost.

The most complex design is considered to be a homemade roller-type pipe bender. IN in this case A pressure roller is used to transmit force. When making a structure, metal and wood can be used, it all depends on how mobile it should be and what force it is designed for.

The features of this design include the following points:

For pipes made from soft materials, wood is more suitable as the main material. It can be used to make a roller. For steel pipes you will have to use metal, since the magnitude of the transmitted force will be significant. If desired, rollers can be purchased or made with your own hands at home.
Design features determine the presence of a movable and stationary roller. In this case, a U-shaped holder is located in the central part.
The bending radius largely depends on the size of the rollers used. That is why the movable roller must, if necessary, be quickly dismantled to install an option with a different diameter.
The holder you install must also be able to rotate.
On installed holder a handle is attached, during rotation of which force will be transmitted. It is worth considering that the handle acts as a lever. That is why the force that can be transmitted depends on its length.

Such a machine is suitable for production in large quantities, since it is quite difficult to make rollers for pipe benders with your own hands. The device is suitable for working with round pipes.

A common question is how difficult it is to manufacture such a mechanism. When using this type of bending machine, the following points should be taken into account:

First, you should study in detail the drawing or photographs of the equipment in question. Only by understanding the principle of its operation can you create effective equipment with a wide range of applications.
The main elements of this design are relatively a small amount of. An example is two pulleys, which can be made of wood or steel, a frame with a lever and a pressure roller. It is quite important to create a reliable foundation that will accept part of the effort.

The principle of operation is quite simple:

The workpiece is placed in the groove of a stationary roller.
The pipe is fixed in the desired position using a clamp.
Using a lever, the workpiece is wrapped around a template, which also uses a roller of a certain diameter.

In order to significantly increase the efficiency of the design, an electric drive can be used. However, it is worth considering that when electric drive It is quite difficult to control the rounding diameter indicator. In addition, the installed electric motor must transmit rotation through a reduction drive, since the rotation speed of the roller is low. To do this, install a gearbox or V-belt drive.

Crossbow pipe benders

A crossbow-type machine has a rather unusual design. It got its name due to its similarities with medieval weapons. The crossbow pipe bender has the following features:

The basis of the structure is represented by a frame, which can be made using angles and channels. The connection of all elements is carried out using welding; detachable methods are not recommended, since the resulting structure must have high rigidity.
After creating the frame, two rollers are attached.
A homemade version can be characterized by the fact that the force is transmitted directly through a mechanical jack. For a pipe of small diameter, the pressure created should be quite sufficient. The force is transmitted through a shoe made of durable metal with a low ductility index.

A crossbow-type pipe bender is more suitable for round workpieces. This is due to the fact that a product with a different cross-section can be greatly deformed under pressure.

Hydraulic pipe bender

When making a pipe bending machine with your own hands, you should decide what type of drive it will be. In most cases, homemade versions have manual drive, since it is easy to manufacture and inexpensive. However, such a design cannot work with workpieces that are made using hard metals. A hydraulic pipe bender allows you to work with workpieces of large diameter and with significant wall thickness, however, the design is quite complex in design and has many features.

When making a machine for a round pipe with a hydraulic drive, the following points should be taken into account:

The force is transmitted through working fluid, which uses oil or water. All lines must have a high degree of tightness and also be designed for a certain pressure.
A compressor can be used to create pressure.
Pressure is transmitted to the working element through a hydraulic cylinder.

A do-it-yourself pipe bender for metal-plastic pipes with a hydraulic drive can have a wide variety of designs. An important element in this case is the drive, which allows you to automate the bending process and increase the scope of application of the device.

Pipe bender from a jack

Most often, when making a homemade pipe bender, a jack is used as the main element. It comes in several types. The jack itself is initially made in order to increase and concentrate the applied force, due to which the structure can lift heavy mechanisms, for example, cars.

A homemade pipe bender made from a jack, as a rule, has a fairly simple design:

The workpiece is clamped between two stationary rollers.
The force is transmitted to the gap between the rollers.
The distance between the fixed rollers largely determines the bending radius and the amount of force required to obtain a certain angle.

As previously noted, when using a jack, you can make a crossbow-type pipe bender.

In conclusion, we note that almost any device is a relatively simple machine, which, due to the distribution of the applied force, bends pipes and other workpieces of a similar type. They are often used for bending products made using non-ferrous alloys and steel. The industrial version of the design outperforms the home-made one, as a rule, in terms of the degree of automation of the process. However, the cost of industrial pipe benders can exceed several tens of times the costs associated with the production of a home-made version. That's why for household use or small-scale production, a homemade pipe bender is more suitable.

When installing most metal structures, bending pipes at different angles is required. A ready-made device for this can be bought at hardware stores, but what if it is unlikely to be useful anymore? Is it worth spending money on a mechanism if it will later gather dust on a workshop shelf? The simplest and most logical solution is to build the device yourself. How to make a pipe bender for a profile pipe? Recommendations experienced craftsmen and video instructions in this article.

A self-made device will help you give the product any shape.

Rolled metal, bent at a certain angle, is necessary in many structures. Among them:

engineering communications in residential buildings: water supply, sewerage, ventilation;
fencing around the perimeter of the site;
home and garden furniture;
greenhouses;
gazebos and canopies.

You can bend any rolled metal, the main thing is to use the right tool for this purpose. Give the required form not only is it possible steel structures, metal-plastic, copper, aluminum can be bent.

Helpful information! To select a pipe bender, you need to take into account not only the cross-section of the product, but also its profile. Simple round pipes can be bent much easier than profile ones. The latter when not the right approach may become significantly deformed or even break.

To use the tool correctly, you need to carefully study the advice of professionals in the video. A do-it-yourself pipe bender for a profile pipe can be made in a simple, manual version or using hydraulics.

Hydraulic devices quickly and efficiently bend any metal parts.

A conventional front pipe bender consists of the following elements:

three metal shafts;
drive chains;
rotating axis;
rotating mechanism;
frames made of metal profile.

Sometimes the shafts are made of wood or plastic, but it is worth taking into account that such rollers will not cope with any pipe. If you do not calculate the resistance of the material, the shafts may simply collapse.

How does the profile bending device work?

Before you start making a homemade pipe bender for a round pipe or profile, you need to understand the principle of operation of the device. The action of the mechanism is based on rolling or rolling. This principle helps eliminate the risk of accidentally deforming and breaking the material. To give the metal the desired shape, it is inserted between the shafts and the handle of the device is turned. The result should be the desired bend.

Do-it-yourself pipe bender for a profile pipe: types of devices

The devices differ in purpose. There are devices for forming turns on steel, metal-plastic, copper, and aluminum products.

Devices can be portable or stationary. Portable models are convenient because they can be installed directly in the room where communications are being installed. Stationary machines are used in production.

Note! Improper use of the machine can lead to changes in the internal diameter of the pipes, wrinkles of the surface and changes in wall thickness.

Manual pipe bender

Soft materials, metal-plastic and copper, are easily bent with a hand-held device. Its design is quite primitive. The bender itself does not take up much space and can easily fit in a small workshop. In addition to the pipes themselves, you can bend reinforcement or rolled metal on it.

Hydraulic device

This device is capable of giving the desired shape to material with diameters up to four inches. The profile material, using hydraulics, can make intricate bends, repeating the topography of the wall.

Making a pipe bender with your own hands for a profile pipe: drawings and diagrams

The simplest device consists of a frame, slats, and two stops. If necessary, a hydraulic system can be added to it. IN complex structures a power supercharger and additional levers are used.

An example of a diagram of pipe benders for a profile pipe with your own hands:

Helpful information! Metal parts of the structure must be thoroughly lubricated to protect against rust. You can even provide a special compartment for automatic lubricant supply.

Model No. 1 – rolling

Assembly algorithm:

The metal base must be secured to a level durable surface and drill holes at the ends.
The steel rectangular plates must also be drilled to secure the rollers.
Secure the plates to the base with nuts and bolts.
Install rollers in the grooves the right size and fix them firmly.
In the center of the base, weld the stands for the central shaft and secure it with a stud and nut.
Provide one shaft with a handle for turning.

Result: You should get a design like in the photo. You can not use a metal base, but attach the plates directly to the base.

Model No. 2

Another pipe bender for a profile pipe with your own hands, of a simpler design, will cope with products with a cross-section of two and a half centimeters.

Work order:

It is necessary to make a device template on paper.
From scraps of lumber, assemble the device according to the template, fastening the parts with self-tapping screws.
Screw the resulting module to the wall. Screw a beam onto one side of the module for support.

Advice! When screwing parts, you need to focus on the diameter of the pipe. It should be easy to insert and lock into place.

Result in the photo:

Model No. 3

This version of a do-it-yourself pipe bender for a profile pipe is even simpler:

A sheet of plywood is screwed to the wall, and the desired bend is depicted on it.
Metal hooks are secured along the line with screws. Metal plates must be attached to each hook; they will additionally secure the material being bent.
It is necessary to provide a stop for the end of the pipe.

Advice! If you don’t have enough strength to manually perform the desired bend, you can use a winch.

Result:

Application of hydraulics

For hydraulic device you will need:

rollers – 2 pieces;
hydraulic jack;
shoe;
channel;
steel plates.

The jack is fixed on the workbench. It will push the pipe into tight gripping rollers. If you prepare rollers of different diameters, you can work with products of any size.

For bending, rolled metal must be heated, especially with outside diameter

To prevent deformation, the pipe must be filled with sand before bending.

If you are not sure of the result, don’t try it. Sometimes it is easier to buy ready-made bends and weld them to the pipe than to correctly give it the desired shape.

Drawing conclusions

It is quite possible to make a simple device for bending rolled metal with your own hands. If you need to manufacture a complex configuration metal structure, better use rolling method. For a couple of simple bends, a device using hooks is suitable.

It is worth remembering that the wrong ratio of force and excessive haste can lead to irreparable deformation of the material.

A pipe bender is used to bend profile pipes. This is a tool designed to deform profile pipes. Devices of this kind are sold ready-made or made independently. The second option is popular, since a homemade pipe bender can be made from improvised materials and it will cost tens of times less.

What is the unit for?

To bend a profile pipe, you do not need to turn to a metal shop for help or buy a special tool. This can be done using two metal posts buried in the ground. However, this method has a significant drawback - the need for physical effort. The result is an inaccurately curved pipe, which is not suitable for constructing a greenhouse, arch or other products.

A pipe bender is designed to be able to produce neatly curved pipe shapes. These units are subsequently used for the construction of arches, greenhouses, ceilings, gazebos, fences, etc. If you set out to build a greenhouse at home, then you need to design a homemade pipe bender. If there are available products and tools for this, then implementing the design of the device with your own hands will not be difficult.

To make a roller pipe bender with your own hands for a profile pipe, you need to take care of the drawings. They are used to calculate required amount material, as well as the costs of producing a home-made unit.

The planned design of the product is applied to the drawing, which depends on the materials available.

Most craftsmen choose to manufacture front-type pipe bending machines. Such products consist of the following components:

Rollers presented in the form of a round steel pipe (the number of required rollers is 3 pieces).
Chain driving shafts.
Axes of rotation.
The mechanism that drives the device.
Profiles that are used to make a base or frame.

Use as rollers soft species materials is unacceptable, as this may lead to them not withstanding high load, and will collapse. It is recommended to use metal round pipes as rollers.

It is worth noting that there are a huge number of manufacturing options for the products in question, but they all operate on the principle of rolling or rolling. It is this principle of pipe bending that makes it possible to reduce the risk of pipe bending and cracking.

A simple pipe bender has the form of a unit into which a profile pipe is inserted, after which the handle is turned, when rotated the pipe begins to move and a bend is formed. When constructing a home-made unit at home, it is important to consider that the bending parameters will depend on the design itself. The closer the pressure rollers are to each other, the smaller the angle.

The simplest pipe bending machine: what materials will be needed

The simplest homemade pipe bender, in which the bend angle is adjusted, is made using the following materials:

Hydraulic jack.
Metal profiles that serve as the basis for the construction of the structure.
High-strength springs - 4 pcs.
Metal shafts - 3 pcs.
Chain.

When designing a pipe bender with adjustable bending angles, two rollers are located on the lower base, and the third is installed in the upper part. When obtaining the desired bend, you only need to rotate the handle, which will move the shaft using a chain mechanism.

To create the device shown in the photo above, there is no need to make grooves to adjust the location of the rollers, which will significantly simplify the work. To obtain such a product, you only need the necessary material and welding machine. The rest is the work of the master. It all depends not only on your skill in welding and grinding, but also on your imagination.

Where does the production of a pipe bender begin?

A homemade pipe bender is made by performing the following manipulations:

Frame manufacturing. The lifespan of the manufactured device depends on the quality of the materials used and welds. Welding is not the only option for creating a base, as you can use a drill and bolted elements.
Set the axis of rotation, as well as the shafts themselves, depending on the dimensions of the drawings. Two shafts are installed below the third. The distance between the axes of these shafts is the bending radius of the profile pipe. This needs to be taken care of even before the shafts are fixed to the base.
The device will not work if the shaft is not activated. For this, a chain drive is used, which can have 3 gears. Chain drive is not mandatory element devices, since only one shaft can be driven to move the profile product through such a tool. If it is decided to equip the device with a chain mechanism, then the chain and gears are taken from the gearbox of a car or motorcycle.
A special handle will help simplify the process of rotating the shafts. With the help of such a handle, a torque will be created to ultimately obtain a curved pipe.

The device of a pipe bender is not very difficult, but its creation must be taken responsibly. Make a device using a quick fix will not be difficult, but whether such a tool will be effective and reliable, it all depends on thinking through every little detail. To adjust the angle or radius of the resulting bend of the profile pipe, it is necessary to make one of the shafts adjustable. This will make it possible to obtain products of different radii, which are used not only for the construction of greenhouses, but also arches, gazebos or entrance gates.

How to make a pipe bender with your own hands: instructions

If you have an example or diagram of a pipe bender, then making the machine yourself will not be difficult. You must adhere to the appropriate sequence of actions. To make a pipe bender for a profile pipe, the following manipulations are performed:

On the shaft you need to place gears, as well as bearings and rings. The production of shafts is entrusted to an experienced turner. If you plan to create all the parts yourself, then you will need three shafts, two of which are distributed on the lower base (a channel serves), and the third is suspended on springs.
The corresponding holes are drilled in the rings, which are needed in order to cut the thread. This thread is needed to attach gears to the shafts.
The shelf for securing the third roller is also made from a channel.
All elements are distributed on the frame and combined by welding or bolted connections.
The first step is to install the frame on which the corresponding structural elements are distributed.
The shelf is welded perpendicularly to the base.
A handle is attached to one of the shafts.
Finally, to adjust the bending radius of the profile pipes, you need to install a hydraulic jack on the top shelf.

If you make a tool according to a template, then no difficulties will arise. To clarify some points, you should pay attention to the following factors:

The pressure shaft located on the shelf must be additionally secured to it. It is also secured with dowels.
The pressure roller is made by performing the following manipulations: a shaft is fixed to the shelf, as well as springs that are attached to pre-installed nuts. After making the shelf, it can be welded to the frame of the main device.
To tension the chain, you need to use a magnetic corner. It will serve as a holder.
The sprockets are fixed with dowels made from Grover.
The drive handle is constructed from a steel tube.
The jack is placed on a hanging shelf.

The design of the simplest homemade unit for bending profiled pipes is presented in the video below.

How to build a hydraulic pipe bender

The design of a hydraulic pipe bender with your own hands is presented in the video below.

Building a tool of this type will not be difficult if you have two 0.5 meter channels at your disposal. The base of such a device included the following elements:

hydraulic cylinder;
stops;
supercharger.

In addition, you should also highlight:

A jack that can withstand loads of up to 5 tons.
There are 2-3 rollers.
Channel - 3-4 mm.
Thick plates.

The principle of using such a tool is that you need to install a profiled pipe into the shoe. Use a jack to set the required bending radius. When the jack is inflated, the rod rises, pressing on the roller. After establishing the bending angle, the pipe can be removed. This type of bending device is relevant when it is necessary to bend a pipe in one place, for example, when installing a heating system.

Crossbow pipe bender: step-by-step design instructions

The crossbow bender got its name because it resembles the shape of a hand crossbow. The cost of crossbow devices is about 10 thousand rubles. To save on the purchase of such a unit, it is recommended to make it yourself.

The photo shows two options for crossbow devices for bending pipes. The first option is a factory design, and the second is a homemade machine. The difference between these two machines is significant, since the factory version is made of steel measuring no more than 2 mm, while for the homemade one, metal 3-4 mm thick was used. It means that homemade unit made not just to be, but for everyday use.

Feeling the difference, every master will want to acquire a crossbow pipe bender, making it himself. The disadvantage of this version of the pipe bender is the fact that it allows you to bend the corrugated pipe at only one point. This is due to the fact that the device is equipped with a fixed shoe. This option is used for round pipes, when you need to get a certain bending radius in one place.

To construct such a device, you need a channel and a hydraulic jack. A special shelf is made for the jack in which it is installed. In the upper working part, two rollers made of steel pipe are mounted between two channels. The distance between the rollers and the heel of the jack must be the same in order to be able to obtain even and neat bends.

Other options for rolling pipe benders

You can make a manual pipe bender using two steel plates, as well as four metal bars measuring at least 4x4 cm. The reliability of the structure will depend on the thickness of the bars. An example of another type of rolling pipe bender is shown in the photo below.

Initially, a frame is made with 3 rollers fixed on it. Two rollers are stationary and are placed on the side posts. A hole is drilled in the upper base (steel plate) and a thread is cut. This thread is needed to adjust the third movable roller. On the reverse side of the installation there is a handle, which can be presented in the form of a wheel. When the wheel rotates, the pipe will automatically roll and bend. The bending radius is adjustable using a threaded connection.

This is not the most simple design However, with the right approach it will last a long time. If you need to make the product easier, then below is a diagram with all the necessary dimensions.

Stationary pipe bender: step-by-step instructions

If you plan to make your own greenhouse from steel pipes, then you will need to acquire not just an ordinary pipe bender, but a reliable product. After all, with this approach you will need to bend more than a dozen profile pipes. To make the greenhouse design neat and beautiful, you need to use a stationary pipe bender.

Before you start making a greenhouse, you need to make sure that you have the appropriate tool for bending profile products. The following elements will be needed to construct a stationary pipe bender:

rod at 25;
6 bearings;
channel.

You will also need a welding machine, with which you will connect all components. Step-by-step instruction making a stationary pipe bender looks like this:

When installing a profile tube of any size, you should adjust the radius of the final bend. This can be done using a jack located under the base on which one of the shafts is fixed. Having adjusted the required bending radius, the handle rotates. The result is high-quality curved tubes. The advantage of a pipe bender is the ability to bend materials of any size and diameter.

Among the disadvantages, we can only note the possibility of operation in one place. It is important to understand that such a device can be used for any need. To manufacture such a device, an investment of no more than 500 rubles will be required. You only need to buy 6 bearings, and all the other elements can be found in every craftsman’s household.

How to bend a pipe with a homemade pipe bender

Making the devices in question with your own hands is only half the battle. After this, you will still need to use the tool correctly. You can watch the video to see how to use the tool.

The methods for manufacturing manual pipe benders, which are suitable for cold bending of pipes, are discussed above. This is an option whereby the material is not subject to heating. This option can be used for plastic materials. To improve bending efficiency, you need to fill inner part products with sand or salt. Filling the internal cavity of the material with sand or salt will eliminate deformation of the pipe, as well as obtain a high-quality bend.

If the walls of the pipe are thick, then it will not be possible to bend it using a cold method. For this, a hot method is used, which involves preheating the bending point.

Note to the masters

Useful advice from experts is always popular and in demand. Based on the experience of the master, you can avoid various mistakes when carrying out the relevant work:

In manual devices, it is not at all necessary to resort to installing a chain drive, since the design will function when only one shaft moves.
To prevent the pipe from sliding off the template used to bend it, you need to use appropriate metal hooks.
If you need to bend a pipe with a large radius, then three rollers are used.
When designing manual machine care should be taken in advance to be able to adjust the bending radius.

The video shows another option for making a manual pipe bender with two stars. Useful thing, which does not require large economic and physical waste.

If you have a pipe bender at your disposal, you can even make money with it. After all, with its help you can not only bend a profile pipe, but also fittings, obtaining the necessary patterns. Curved reinforcement is used to make decorative elements on entrance gate, canopies, awnings, etc.
