Pipe bender KACHOK - QUALITY OK!
Arched and dome-shaped roofing structures have become fashionable with the advent of flexible roofing materials. This is the well-known polycarbonate, soft roof, various filled plastics, flexible slate and corrugated sheets. The need and opportunity arose to assemble lightweight and portable structures, roofs over shopping pavilions, roofs over swimming pools and canopies. What could be simpler: use a “KACHOK” pipe bender to bend profile pipes into an arc and attach cellular or monolithic polycarbonate to them.
I would like to tell you in more detail about the popular pipe bending machine “KACHOK” for profile and round pipes, which is suitable for many jobs and performs almost all necessary operations. It was developed for small businesses and blacksmith shops. Please note that the pipe bender is compact and heavy. Its weight in the package is 45 kilograms. Dimensions: 450x450x540 mm. You can't tell from the photo, it looks attractive and even beautiful. The entire body of the pipe bender is designed in such a way that by installing it on the table and screwing it to the table with four bolts (not included in the kit) through the holes in the base, you can immediately start working.
What kind of work can be done on the KACHOK pipe bender? You can bend profile pipes of 15, 20, 25, 30, 40, 50 mm and even 60x30 mm into an arc. Most often, arcs are bent, which are subsequently used for greenhouses, canopies, canopies, fences, gazebos, pergolas and other complex non-linear structures.
Rollers for rolling on a pipe bender profile pipe are located on the drive axles. The shafts are mounted on bearings. Sprockets and a chain drive are installed on the shafts. If you rotate the handle, the rotation is transmitted to all axes, so to speak, “all-wheel drive.” It is easier to twist and pipe slippage is practically eliminated. In addition, the roller shafts have a fine notch, which provides additional adhesion of the rolled pipe to the rollers.
This pipe bender can easily be converted into an electromechanical one.
The pipe bender kit also includes rollers for round pipes. Rollers for pipes with a diameter of 20, 25, 30 mm. A round pipe is rolled easily and the walls remain smooth without dents or corrugations.
You can work with a strip of maximum 40x10 mm. The strip on these rollers rolls perfectly. When I needed hoops with a diameter of 1 meter from a strip of 30x4 mm, I made them easily. The edge strip is rolled onto external rollers that come complete with the pipe bender. The maximum you can work with is a strip of 30x4 mm.
Our tests have revealed good performance of the pipe bender and high quality execution of individual elements. Simple and reliable design. Jock - QUALITY OK!
Servicing a pipe bender is not difficult. It is necessary to periodically lubricate the pressure roller screw and sprockets. Any lubricant is suitable, LITOL can be used.
When assembling a heating or water supply system from metal pipes, it often becomes necessary to bend them to give one shape or another. For these purposes, there is a special tool - a pipe bender, which you can either buy, although it costs quite a lot, or make it yourself. In this material we will talk about how to make a pipe bender for a round pipe yourself, as well as what types of these products are available.
Scope of application of the tool
It is worth noting that pipe benders for round pipes have a fairly wide range of applications, and this is not only plumbing work. By the way, when installing plumbing fixtures, the need to modify the pipe contour does not always arise. Typically, swivel fittings and bends are used to create bends in pipelines. By bends we mean sections of pipes bent according to standard templates in the factory.
There are some restrictions for bends:
- standard set of rotation angle options – 45º, 60º, 90º, 180º;
- bending radii can be 1 or 1.5 DN;
- The connection is welded only.
In some cases, it is impossible to fit an individual heating or water supply system into such a strict framework, and it is not always acceptable to use the welding method of fastening. Then you will definitely need it homemade pipe bender for round pipe.
In homestead and country farms there may be many situations when it becomes necessary to bend pipes. This includes the creation of greenhouses and greenhouses with unusual shapes, and installation of frames for grapes or climbing flowers, and construction summer shower or a small fence, in short, there are many options. All these structures are based on a frame made of round pipes or profiles that need to be given one shape or another. This is where manual round pipe benders come in handy.
Let us note that professional craftsmen do not hesitate to use such hand tools, because they perfectly meet all the requirements and parameters of the owner. A hand-crafted tool allows you to perform high-quality work, since it is very convenient to use.
Types of devices
In order to classify products into various categories, several criteria are used:
- Drive type – manual, automatic, hydraulic.
- Installation method - portable or stationary.
- Operating principle.
According to the principle of operation, all pipe benders can be divided into several types:
- Winding. The stop is located at the beginning of the bend. Using special clamps, the pipe is pressed against a movable template roller. This roller begins to rotate, passing the pipe between itself and the stop. This is how bending is done.
- Run-in. With this method, the pipe is fixed near a stationary template. The pressure roller begins to rotate around it and gradually bends the pipe to the size of the template.
- Rod or crossbow method. The pipe is fixed between two fixed rollers. Pressure is applied to it centrally using a template located on the rod. It gradually lowers, bending the pipe in the center between the support posts.
- Rolling (rolling). In this case, pipe rolling involves bending using two rotating support rollers placed along the same line and one central template. The bending radius will depend on the relationship in which these elements are located. As a rule, the pressure on the pipe is exerted by the central roller.
It is worth noting that the first three methods of work have one common drawback - in them, the bending radius of the pipe directly depends on the template.
Bending a pipe using the winding method, as a rule, is carried out only on industrial equipment, because made by our own pipe bender by hand for a round pipe it is not suitable for these purposes. Products subjected to the crossbow processing method appear weak point– where the top of the template impacts the steel. This area is subjected to intense pressure and becomes brittle, weakened and thinned. In some cases, the pipe may even burst if its walls are thin enough.
But the rolling method is used most often to form pipe configurations. Moreover, it is used on industrial enterprises for the production of bends.
In order to properly manufacture a tool, you need to choose its model taking into account the relationship between the bending radius and the cross-section of the pipes. This data can be found in special recommendations in table form. And, although the figures given there are optimal, the bending radius can still be reduced.
However, for this purpose you will need a mandrel, which will significantly complicate the work. If we talk about factory conditions, then in addition to the mandrel, hot rolling is often used in production.
At the same time, hot rolling can be performed at home if you have a stationary metal pipe bender with a fixed frame at your disposal. Then a blowtorch or gas burner is used to heat the pipes.
DIY pipe bending tools
Since manufacture homemade device for bending pipes, you can use improvised or used components; the cost of such a tool will be quite low (more details: " "). Moreover, to make the simplest pipe benders for a round pipe with your own hands, no drawings are required. For example, consider quite simple design of this device.
To bend a pipe, one of its ends is fixed between metal elements and pressure is applied to the opposite end until it acquires the desired shape. After this, the pipe is left in this position for some more time so that it does not straighten. To do this, metal pins are also threaded through the ends of the pipe, which are welded to a temporary jumper.
Actually, this is the simplest type of pipe bender, which is not a problem to make. But there are also more technologically advanced products. We will write about them below.
Manual pipe template bender
This tool produces bending using the rolling method. It is made of wood and equipped with a manual drive.
First, according to the drawing, a wooden template is made, the shape of which will coincide with the bending radius, and the thickness should be greater than the diameter of the pipe. Profiling cut on the end of the template will make it easier further work with a tool. To get the desired profile, you can take two boards, the cutting line on which is beveled inward.
The base to which the template will be attached must be stationary. A stop is screwed to the platform on one side, after which the pipe is tried on. If the length of the lever is not sufficient, you can insert a piece of reinforcement into the pipe. There is no need to rush during bending - it is important that the pipe does not move during the work and clearly corresponds to the shape of the template.
Of course, such a primitive mechanism is not something intricate and technically complex. However, it is quite acceptable for home work, especially if you need to bend thick pipes.
Roll-type pipe bender made of steel
The most popular among homemade instruments is a rolling pipe bender. The templates in it are made from pulleys from engines. Although, some prefer to use washers with different diameters or turn the part on lathe. In this case, it is not necessary to draw a drawing, but it is advisable, for example, so that a turner can correctly turn out parts for pipe benders for a round pipe.
Such hand tool The break-in type is made by many zealous owners who are constantly making and improving something in their home. The advantage of such a pipe bender is that it can work with plumbing pipes of any standard diameter. And to make the applied force greater, you can make the lever longer.
Homemade winding machine for bending pipes
According to the principle of operation, such a tool is similar to a break-in tool. However, with its help it is possible to shape the pipes into a ring shape, which is impossible to do with any other device. If you examine the drawing of the device in detail, you will notice that the cheeks of the template pulley can be dismantled in order to remove a workpiece in the shape of a circle from it.
It is worth noting that a pipe bender of this design can be made from any available materials, including wood, metal or textolite.
How to make a hydraulically driven pipe bender for round pipes
If we are talking about doing more than just some household chores repair work, and about professional activity, then you should think about making a more complex hydraulic pipe bender. With its help, when bending pipes, it will be possible to reduce the cost of physical effort, because the load will be on the hydraulic jack.
At the stage of drawing up a drawing of the device, it is necessary to foresee what material the sidewalls will be made of. A reinforcement rod with a cross-section of 18-20 mm, as well as corners with a side of 25 mm, are optimal for this. In addition, for the sidewalls you will need 10 mm thick sheet iron with drilled holes for fixing the supports.
As a support, use a tube of the appropriate diameter, into which you will need to weld a bolt with a cross-section of 18 mm. There will be a semicircular hole in the center of the support, which also needs to be reflected in the drawing. The workpiece will have to rest against this recess and will be bent using a hydraulic manual pipe bender.
To create a punch, you will need sheet metal 4 mm thick, from which semicircular blanks will need to be cut. The radius of these parts must correspond to the planned bend radius of the pipe. At the next stage, take a pipe with a cross-section of 32 mm and cut it into two parts. One of the parts is bent to the shape of the blank plates, and then all the parts are welded. For additional strength of the punch in a hydraulic pipe bender, jumpers are welded inside it to provide stiffeners.
A tube is welded in the central part of the platform. Its purpose is to support the hydraulic drive, which is used as a jack. All this must be worked out and included in the drawing, according to which the hydraulic pipe bender will be assembled. In addition, such a scheme will allow you to prepare a list of materials and components that have the necessary parameters. In this case, a number of elements for the tool will need to be pre-ordered from a turner.
Thus, assembling one or another type of manual pipe bender is not so difficult. Moreover, there are a lot of options and drawings of finished products that you can use to make your own necessary tools on the farm.
Owners country houses or personal plots, when updating a pipeline or carrying out 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, what 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 to describe the step-by-step manufacturing, 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.
- 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 out of wood with your own hands. From a technical point of view, such a device is the simplest; operation does not require additional parts, 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 with reverse side, bending 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 high-quality metal hooks at any hardware store;
- 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 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.
Pipe bender made of cylinder and rollers

Video 3. Do it yourself
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.
To work with pipes or angles, a special machine called a pipe bender is required. This design allows you to bend metal elements to a given angle. If necessary, you can make a professional pipe bender with your own hands, which is used in the most various industries industry. 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 when taking into account following features his devices:
- 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. A special pipe bender for aluminum pipes is 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 similar device It 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, homemade design may 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 complexity of the high complexity of the underlying 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 relatively small sizes, can be portable, it is possible 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 in question can be classified according to quite a large number signs. Available for sale universal options execution, as well as for highly 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. Last time greater distribution received an electric drive, 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 an electric pipe bender with your own hands. 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 performed as portable design. 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.
Homemade pipe bender for metal-plastic pipes can be of 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 when setting up production activities of various 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 workpieces 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.
Most complex design is considered a homemade roller-type pipe bender. 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.
- A handle is attached to the installed holder; when rotated, 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 pipes round section.
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.
- This design has a relatively small number of main elements. 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 a working fluid, which is 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 is why a homemade pipe bender is more suitable for household use or small-scale production.
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 make 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.
Lever-type pipe benders have become very popular. 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 structures includes a couple of additional templates for pipes of 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 finished product turned out to be 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.
Pay attention!
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.
