A real owner always has a lot of different tools that he uses for his home and yard. And he can certainly make a pipe bender for profile pipe with your own hands according to the dimensions and drawings that we will provide below. Such designs may be different, and we will not be able to cover them all, but the material provided will be enough for you.
Homemade pipe bender
Buy in a store or make it yourself
Profile pipe bender "Hercules"
The one you can buy in a store may have a different type of drive and different principle actions, but this is not always good. Firstly, to work on it you need some experience, and secondly, such devices are expensive. For these reasons, making a homemade pipe bender from scrap materials is not only profitable, but also practical, since when assembling the tool you will know the slightest nuances of its operation.
Why do you need a pipe bender?
Main elements of the machine
Today, profile pipes of different cross section is the most popular metal product. They are used to make frames and lathing, fences and railings, with their help they expand balconies and even build various architectural structures in the form of extensions or separate rooms. But sharp turns are not always used in construction - sometimes a smooth transition is needed, and in these cases you can’t do without a pipe bender. As a rule, such a machine allows you to bend a profile to an angle of 180⁰, that is, the device allows you to make a circle.
Main design elements
Principle of operation
To manufacture a particular machine design, you should look through several diagrams to determine the set of parts. The fact is that, if necessary, all the components of the units can be purchased for money, but you can also use the materials that you have on your farm and not pay anything for it. In most cases, home craftsmen opt for frontal structures and for this you must have:
- three metal rollers (rollers);
- drive chain;
- axes of rotation;
- drive mechanism;
- metal profiles(channels) for the frame.
Sometimes, in the absence of metal rollers, they are replaced with wooden or polyurethane ones, but... Such a rolling mechanism will not withstand long-term load, that is, the machine will serve its purpose, but not for long. Is there any point in wasting your labor for short-term benefit if, with some effort or even paying a certain amount, you can find steel rollers?
Scheme simple pipe bender with dimensions in mm
As you understand, the process of profile deformation occurs using rolling, that is, the pipe is rolled over rollers (rollers), which eliminates breaking and cracking. To roll (bend) a profile, it is inserted into the rolling line (between the rollers) and pressed from above with a screw device or a jack to the desired bending radius. Then, when the feed handle is rotated, the pipe moves and the bend runs along its entire length. It turns out that this manual drive, which is driven by muscular force, but at home such a mechanism is very convenient.
The profile is pressed using a jack
To assemble the simple pipe bender in question with your own hands, you will need:
- jack (preferably rack and pinion type);
- metal profiles with a shelf for horizontal and vertical frames;
- springs made of alloy steel (they are distinguished by high strength);
- three steel shafts with bearings;
- drive chain (can be from a bicycle or moped);
- gears (driver and driven);
- Thick reinforcement for axles and drive handle.
Video: pipe bending process
As you can see, it is easier to make a profile bending machine with your own hands using the existing drawings, and photo and video materials only help with this. The profile bender shown in the picture is driven by a handle that rotates the shaft with the drive gear. Using a chain, rotation is transmitted to the shaft with the driven gear, and the third shaft presses the profile from above to the required bending angle. Everything is very simple.
Mechanism manufacturing process
Bending device drawings
If you are interested in how to make a profile bender, then you will have to perform a number of actions that will ensure this reliability of the mechanism, and this is:
- production of a powerful frame assembled using welding and bolt ties;
- according to the terms of the drawing (technical specifications), make and install rotation axes for the rollers. There are three of them - two rolling and one clamping;
- To rotate the rolling rollers, you need to provide a chain transmission, that is, weld (evenly) the drive and driven gears;
- Weld a handle for rotation onto the drive gear.
Manufacturing nuances
Ready pipe bender
If you have everything in stock necessary details, then it is not difficult to make a mechanism for bending the profile. First of all, you need to take into account that all rollers must rotate on bearings - the accuracy of rotation will ensure correct rolling, without failures or breaks. The drive and driven gears must be correctly centered - a deviation from the center by at least 0.5 mm will lead to incorrect deformation (the bend will be uneven).
The pressure shaft must also be centered - the accuracy of the bending angle depends on this. It is best when the dimensions of all three shafts are the same - the rental results in the clearest. The rolling accuracy also depends on the rigidity of the clamp, so the shaft must be well fixed.
Hydraulic pipe bender
Hydraulic drive mechanism
To make a hydraulic one for a profile pipe with your own hands according to ready-made dimensions and drawings, you will have to spend a lot more labor and resources. However, it can be done and we will now look at the procedure. For assembly you will need:
- hydraulic jack with a lifting capacity of 5 tons;
- shoe;
- three shafts;
- channel for frame;
- metal plates (thick).
Video: hydraulic driven mechanism
To correctly bend the profile, it is inserted into the shoe and both ends are secured. After this, the jack is activated - it presses on the pressure shaft and sets desired angle bending After rolling, the jack is loosened several turns and the pipe is removed from the device.
Drawing with dimensions in mm
The jack is attached to metal plate using bolted connections. But in such a mechanism, the most important thing is the shafts, which must tightly grip the profile - the accuracy of bending depends on this. The shafts are fixed at the same height and gears are welded to them. The shoe is attached below the shafts, and the ratio of the shoe to the shafts determines the bending angle. Fixation occurs using bolts.
Bending Methods
Cold profile bending
If you have read all the descriptions, looked at the photos and videos, then the bending process itself is unlikely to confuse you. If you decide to make a hydraulic device, then you can bend pipes of any thickness on it - the most important thing is that the shafts (rollers) can withstand it. But I would like to mention one nuance - arching can be not only cold, but also hot. Heating usually occurs using gas welding, this is very convenient, especially since you can heat only part of the pipe, that is, the section that needs to be bent.
It can be said that cold method arching is the simplest and if you are working with thin-walled pipe, then there is no need to heat it at all. But there can also be problems here - this is the seam. Profiles are not always made with high quality and bad seam when bending, it simply diverges. This can be avoided by heating, but not always. A low-quality pipe will remain that way and no amount of heating will help. However, if you use a profile for the frame, then a small crack along the seam will not become critical.
Note. Be that as it may, hot bending is still the highest quality. Hot metal it turns out to be most clearly curved, without any interruptions.
Pipe bender with accessories
For a profile pipe, it is not at all necessary to acquire any special qualifications - ordinary care and a few recommendations from specialists are enough. In manual devices, the system consists of a drive and driven gear welded onto shafts and a clamp (a jack can be used instead of a shaft). Sometimes the profile can slip off the rolling mill and in such situations, hooks are used for fixation. For the most precise bending, the shafts must be movable.
Note. To maintain the bend radius, it is best to make a cardboard or wooden template. Even if you use a simple hand pipe bender, a template will always ensure accuracy.

Conclusion
You have read an article with drawings, photos and videos about how to make profile bending with your own hands. As you can see, this is not very difficult, but you need to collect all the parts first so that the work does not stop because of the little things.
To every owner of a big garden plot or a small dacha, at least once in your life (at least) you may need a pipe bender - a device for bending a profile pipe.
For example, this could be a blank for a greenhouse frame or canopy, gazebo, or any other metal structure.
Metal sales centers and other industries usually use factory-made devices, but this pleasure is far from cheap. To save your budget for more pleasant expenses, it is more profitable to start making the device manually, on your own.
For this design, as they say, “you don’t need a lot of intelligence,” and there won’t be a shortage of parts either; you can actually create the drawings of a pipe bender yourself.
Pipe bender options
You can bend the pipe using the “home” method, fill the pipe with sand, heat it until red blowtorch or gas burner, then bend the pipe. This method is not recognized as a priority among craftsmen; it is labor-intensive and does not provide sufficient accuracy; creases and deformations may also appear.
To get perfect bent pipe, in compliance with the standards and specified parameters, without causing damage to the source material, craftsmen use specialized pipe benders in their work.
Pipe benders have become increasingly popular lever type. This elementary invention works on the principle of a “lever” - the force is concentrated in a certain place, and the bend merges with the shape of the template you created, which can most often be removed and replaced with another.
Most often, the kit of such designs includes a couple of additional templates for pipes different diameters. There are units of similar design, manual pipe benders, drone or crossbow benders, they allow you to bend short sections of round steel pipes, subjecting them only to cold processing.
Crossbow devices are very compact and are valued in the field of installation and engineering communications.
What is the job of a pipe bender?
The principle of operation is completely simple, it consists in heating the pipe, the pipe heats up red and becomes very plastic, malleable to change. Each type of pipe bender has its own range of capabilities.
The main functions are the quality of bending and the ability to bend pipes different sizes and diameter.
With the help of additional rolling devices, a bend of a larger diameter is achieved. The device operates using shafts, there are three of them in the set.
Guides and pressure. The pipe passes through moving elements, the degree of bending is set by the force of the pressure roller. If the radius of curvature of the finished product is small, the procedure should be repeated.
Bending a pipe according to a template
In most cases, the simplest option, suitable for absolutely all craftsmen, even beginners, is a wooden template. Boards are selected according to the thickness of the pipes being bent; be sure to leave a couple of centimeters of board space.
To prevent the profile from moving off the template during operation, a slope is left at the ends. The template is rigidly fixed to the floor or other stable surface, and a stop for the pipe is installed nearby.
The profile is inserted into the gap between the template and the stop, smoothly and carefully press on its other end, pressing the pipe against the template. A winch or lever will make the job easier.
A huge advantage of this process is cost savings and ease of execution.
Note!
Any device has disadvantages, and this method is no exception. The bend is inaccurate, of poor quality, and the template will be disposable (apply only to one pipe diameter).
Snail pipe bender
When stamping identical blanks in large quantities with a small radius of curvature, a snail pipe bender will become indispensable.
Its advantage is its small size and ease of operation. The disadvantage will be the limitation of the radius of curvature, but not large sizes.
Rolling pipe benders
The niche of versatility and practicality is occupied by hand-made devices - rolling pipe benders (bending machines), on such machines you can make any bending angle.
The configuration is not particularly different from other models; they also have a base and shafts. The movable roller presses the pipe, and it is pulled through by the rotation of the drive shafts.
Note!
Pressure can be increased using a winch, levers or electric drive. However, for the production of a house, such a design is quite complex to implement.
To reproduce such a unit, many turning and welding work. If you decide to make such a model, it will serve you for a long time and will delight you with its functionality.
How to make a pipe bender with your own hands, the question is modern world quite relevant. To make the task easier, you can find a photo of a pipe bender on the Internet to roughly understand what it should look like.
There are also many pipe bender drawings that are easy to use. After reviewing all the information and assessing your strengths and availability necessary components, calmly get to work.

Note!
When installing most metal structures, bending pipes at different angles is required. Finished device You can buy it at tool 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. If handled incorrectly, the latter can 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 regular 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 round pipe or profile, you need to understand the operating principle 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, bend easily manual 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 required form material with diameters up to four inches. Profile material using hydraulics it can make intricate bends, repeating the relief 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, you can add to it hydraulic system. 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 – rental
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 of the required size into the grooves and secure 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.

Video: do-it-yourself manual pipe bender for a profile pipe
To construct a pipe bending device, you can use ready-made drawings. The video “How to make a pipe bender for a profile pipe with your own hands” will reflect the manufacturing procedure and how to use the resulting tool.
- 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 a type of rolling mill designed for bending pipes of various sections and diameters under a given radius.
How exactly it works and how you can make it yourself at home will be discussed in this article.
Purpose
Very often when working with metal pipe regular (round) and rectangular (profile) sections require bending them to a certain angle. This need arises regardless of the type of work - whether it is laying a pipeline in a workshop, installing a split system in an apartment, or welding a bench or gazebo from a corrugated pipe at the dacha.
Thin tubes, for example copper tubes, often used in air conditioning systems, can be bent by hand, but manual bending is always non-standard, or, more simply put, crooked. This is unacceptable for serious production. And the fat one steel pipe, especially a profile one, cannot be bent manually. This is where pipe benders come to the rescue. They can carefully, precisely bend a pipe along a given radius, preventing ruptures, thinning of the walls and other deformations of the metal. 
Principle of operation
The operating principle of any pipe bending machine, despite the wide variety of designs, is the same:
- The tube is either fixed at two points, let’s call them A and B, and at point B, located between them, a force is applied to it, which leads to the formation of a bend. In fact, this is a type of press.
- Or only two points are used, one of which fixes the pipe in space, allowing it to slide freely back and forth (in one plane), and the second is a rotating roller clamp. The end of the profile is clamped in the clamp, the roller rotates a certain number of degrees, and the profile bends accordingly.
There are many types of pipe benders, but they all have similar design elements: they have one or two stationary fixation points for the pipe and one movable. Its movement in a given plane leads to bending of the profile.
Rollers or rollers are always used as support points. Bending of the pipe in rigid clamps is possible, but can easily lead to rupture of the material. If the profile can slide freely in the rollers, then it is not damaged.
To bend profile pipes with a cross-section in the form of a rectangle and square, the same principle is used as for round section. Only the pipe bender had to be assembled on rollers with a corresponding groove, otherwise this would cause deformation of the profile, and possibly failure of the entire mechanism. 
Varieties
First of all, pipe benders are divided into manual and automatic. The first ones are designed to work with a profile of a small cross-section, up to 40x40 mm, since it is impossible to bend a thicker pipe even with the help of a lever. They are mainly used in everyday life, and there are mobile and stationary devices.
Automatic rolling and bending mills are designed for industrial conditions. As a rule, they are stationary.
They are equipped electrically driven from an engine of appropriate power. There are hydraulic or combined - electrohydraulic models.
The main classification is based on the principle of operation:
- jack (or crossbow),
- rolling,
- winding
The first two types are structurally very similar to each other. There are two rollers through which the pipe is pulled. A third roller or semicircular stop is placed on the jack or press, which applies pressure to the profile. The only difference is that during rolling, the profile is driven under a pressing roller at a certain speed, and the roller itself is fixed motionless. And when using a “crossbow” type pipe bender, on the contrary, a descending press applies pressure to a stationary section of the profile. 
The winding type means that the material to be bent is fixed in one roller (or system of rollers) and wound on another. 
Each type of design has its own advantages and disadvantages:
- The “crossbow” is structurally simplest; it is easier to make at home from an ordinary jack. But it is difficult to carefully bend the end of the pipe with its help; in addition, when bending to a large radius, it can lead to metal rupture.
- The rolling machine provides high quality bending to any radius, but requires a motor to pull the pipe. This type is most often found on factory floors.
- Winding can be both stationary and mobile (manual). It is especially suitable for small and medium diameter pipes. Its main disadvantage is the inability to change the bending circumference and vary the radius: they always depend on the winding roller.
Note: CNC pipe-bending machines are actively used in industry, which can make any bent structures from pipes according to the laid down program.
How to make a pipe bender with your own hands?
If you need a pipe bender for repair work around the house or dacha, and the work is planned with small-diameter pipes, then you can not buy an expensive device, but install it yourself using improvised means. There are countless manufacturing options.
Before starting work, you will need to decide on the cross-section and profile shape of the pipes that you will bend. The width and shape of the roller groove must exactly match the diameter and cross-section of the pipe, otherwise it will either get stuck in them or will “walk”, which will lead to uneven bending or other deformations. The pipe should fit between the rollers like a glove and not get stuck or dangle. Or it is necessary to use cylindrical rollers without a groove and control the broaching manually.
The following drawings may also help you in your work: 
Manufacturing of rolling type pipe bender
- A welded frame is mounted on any suitable base. Two support rollers are installed in it. IN in this case in the figure, the distance between them can be varied due to installation in grooves - the greater the distance, the greater the bending radius.
- The rollers are connected to each other via a pulley bicycle chain, drive belt, etc. so that they rotate simultaneously.
- A structure consisting of a support roller with a holder and a simple screw mechanism is welded or bolted to the frame. Instead of a clamping screw, you can use a regular jack.
The principle of operation is simple: the material to be bent is inserted between the support rollers, and the drive roller is lowered from above, providing the necessary deflection. The stronger the pressure, the more the profile bends. If it is necessary to bend a large section of pipe evenly, for example, to form the base for the roof of a greenhouse, the rollers are driven by a belt or chain (manually or using an electric motor), as a result of which the pipe is pulled and bent evenly.
Manufacturing of winding type pipe bender
If there is a need to bend pipes of a small cross-section, but with a small bending radius, then you can assemble a homemade winding-type pipe bender.
The design is somewhat similar to a twisting machine for home canning. The main part is two rollers with rectangular grooves exactly in the shape of the pipe. The drive roller (large in the picture) is attached to any base. It will provide the radius and rounding of the pipe bending.
The small roller is mounted on the lever. The design works as follows: one end of the profile is inserted into the clamp. The profile is tucked between the rollers. Using muscle force (usually), the lever “winds” the pipe onto the drive roller.
Bending profile pipes is a fairly common procedure for which it is used special device- pipe bender You can make a pipe bender for a profile pipe with your own hands, or you can purchase it at construction market or in the store.
Serial devices differ in their operating principle; they may have different types drives, however, operating any of these devices requires some experience. Restricts the use of devices manufactured in production conditions, and the fact that they are not cheap. A good solution in all such situations would be self-production a device designed for bending profile pipes, for which you can use improvised means.
Required design elements
To make a pipe bender with your own hands, you can use the drawings various designs. Their choice is determined mainly by what materials you have. Most often they opt for front-type pipe benders, the design of which includes:
- three rollers (shafts), which must be metal;
- drive chain;
- axes of rotation;
- a mechanism that will set in motion all elements of the device;
- metal profiles from which the frame of the device will be made.
To understand how to bend a profile pipe on a homemade device, it is important to understand the technology used for this process. As a rule, pipe benders use the rolling or rolling principle, which minimizes the risk of kinking and damage to the pipe.
To make a bend on a profile pipe using such a device, you need to insert it between and turn the handle. The use of such a simple bending device allows you to obtain bends on a profile pipe that fully comply with the specified parameters.
To make a simple machine for bending profile pipes, you will need the following structural elements:
- ordinary jack;
- metal profiles and shelf necessary for making the frame;
- springs with high strength;
- shafts in the amount of 3 pieces;
- drive chain;
- a number of other structural elements.
When using such a device, the operation of which can be seen in one of the videos below, the pipe is laid on two side rollers, and a third one is lowered on top of it, creating the required force. To give the pipe the necessary bend, you need to rotate the handle that drives the chain and, accordingly, the equipment shafts.
Pipe bender manufacturing process
To make a receiving device, you need to follow the following procedures.
- Prepare a reliable frame, the elements of which are connected by welding and bolted connections.
- Using a previously prepared drawing, install the axis of rotation and the shafts themselves, two of which are located above the third. The bending radius of the profile pipe depends on the distance at which the axes of such shafts are located.
- To operate this bending mechanism, a chain drive is used. To complete such a transmission, it is equipped with three gears, and the chain itself can be picked up from an old car, motorcycle or other equipment.
- To operate such equipment, a handle is needed that is connected to one of the shafts. It is through this handle that the required torque is created.
Instructions for making a pipe bender
Making a pipe bender for a profile pipe yourself is not at all difficult if you adhere to the following technological sequence.
- Gears, bearings and rings are placed on the pressure shaft, which are connected to it using a key. First, a drawing of such a shaft, races for bearings and rollers is developed, then these parts are turned, which is best entrusted to a qualified turner. Total for of this device it is necessary to make three shafts, one of which is suspended on springs, and the other two are located on the sides.
- Then it is necessary to drill holes in the rings, which are necessary for making grooves and cutting threads.
- Now you need to make a shelf, for which you use a channel, in which you also drill holes and cut the threads required when installing the pressure shaft.
- After completing the preparatory measures, the entire structure of the equipment must be assembled, for which welding and bolted connections. First of all, the frame is installed, which also serves as the legs of the pipe bender.
- The next step is to hang the shelf with the pressure shaft attached to it, for which springs are used. After this, you need to install side support shafts on the homemade pipe bender, on one of which a handle is attached.
- The finishing touch is installing a jack on a pipe bender.
Some subtleties of implementation installation work:
- the pressure shaft, fixed with keys, is additionally screwed to the shelf;
- installation of the pressure shaft is carried out according to the following scheme: the shaft is installed on a shelf to which nuts for the springs are pre-welded; after the installation work is completed, the shelf is turned over and suspended on the springs;
- The chains are tensioned using magnetic corner, which is used as a holder;
- when tightening the sprockets, keys are used, which are pre-made from the Grover;
- the drive handle for the bending machine is made with a rotating tube;
- jack for this homemade device installed on a suspended platform using bolted connections and welding.
Manufacturing of hydraulic pipe bender
On the Internet you can find many photos and videos of how to make your own device for bending profile pipes with a hydraulic drive. The process of manufacturing such a pipe bender, equipped with a hydraulic cylinder, injection device and pipe stops, is a rather labor-intensive undertaking.
In the drawing and in the design of such a pipe bender, the following elements can be distinguished:
- hydraulic jack with a lifting capacity of at least 5 tons;
- shoe;
- rollers in the amount of 2–3 pieces;
- powerful metal channel;
- thick metal plates and other parts.
To perform the required bending of a profile pipe using a hydraulic device, it is necessary to insert it into the shoe and fix both ends. After this, you need to use a jack, which, with its rising rod, presses on the roller, which acts on the pipe and bends it. Once the required bend angle is obtained, the process can be stopped and the pipe removed from the pipe bender by turning the jack handle several times in the opposite direction.
Methods for bending pipes using a homemade machine
The question of how to bend a profile pipe using a homemade pipe bender is unlikely to confuse you if you read a few more recommendations. Hydraulic machines can be used to successfully bend profile pipes from different materials, as well as thick-walled products. This operation can be performed using either a cold or hot method, which involves preheating the pipe section.
Thus, a manual hydraulic bending machine can be used to influence the pipe in two ways:
- cold;
- hot.
Cold bending is the simplest bending method, which is used for pipes made of plastic materials. The subtlety of this process is to fill the pipe before the flexible one with sand, salt, oil or cold water. This allows you to get a better bend without significant deformation of the pipe.
If you are interested in the question of how to properly bend a profile pipe with thick walls or made from materials of increased rigidity, then the answer to this question is to use the hot bending method.
The question of how to bend a profile pipe as accurately as possible and without unnecessary labor costs will be answered by several useful tips from qualified specialists.
Removable casters different shapes will allow you to work comfortably not only with profile pipes, but also with round ones
- In manual pipe benders for bending profile pipes, you can not use sprockets, but assemble a structure based on one drive roller. Instead of a pressure screw, such pipe benders often use a jack.
- If you are bending according to a template, then to prevent the pipe from sliding off it, you can use metal hooks as stops.
- If you need to bend a profile pipe under a large radius, it is best to use a pipe bender with three rollers.
- To get a more versatile bending machine, you can make its thrust rollers movable. This way you can change the bend radius of the pipe.
In the video below, the master shares his experience in building a pipe bender from scrap materials.
In order to strictly observe the dimensions of the required pipe bend, it is best to perform this operation using a template made of wood. Even the simplest manual pipe bender using such a template will allow you to bend a profile pipe with precise compliance with the specified parameters. By the way, such templates are mainly made to implement the simplest manual methods flexible.
