Not everyone is able to buy a factory machine for bending various metal profiles, and the need for it may be rare. In such situations the profilegib - the simple manual device will come to the rescue, which you can make yourself.
One of the options for profile bending
What is needed for profile bending?
It is quite easy to make a profile bend with your own hands, and it is even easier to apply. As its name implies, it is necessary for giving the bent form of metal profiles of various section. With the help of profile bending you can perform the following technological operations:
- bending of workpieces with a solid profile of square or rectangular cross section;
- flexible of different types of rolled products (channels, I-beam, corners);
- providing a curved shape of the pipes, made of different metals;
- performing bending of metal rods of different cross sections.

The design of profile benders is designed as follows, that their working bodies - rollers - can affect a particular area of the workpiece, and apply pressure along its entire length. Due to the features of your device, profile bending machines effectively perform bending of metal profiles without their preheating and allow to obtain contours with different bending angles - up to 360 °.
Profile bending makes it possible to obtain metal contours with different or identical bending angles, symmetrical or asymmetrical configuration. It is possible to make a bend of metal preparation in the horizontal or vertical plane by means of such device for one hire through its rollers..
Profile bending allows to receive bent metal products of the following configurations:
- closed and open;
- spiral, made of metal profiles or pipes;
- circles of different diameters.
How electric, and manual profilegiby are actively used for production of details and the equipment for power, oil refining, chemical, furniture, construction and many other industries. Such devices are widely used in small private workshops.
Types of profile bending machines
Profile benders are divided into three main categories.
Hydraulic
These are the most powerful of profile benders, used mainly for equipping industrial enterprises. The profile bending machine of hydraulic type belongs to the category of stationary equipment, with its help at the industrial enterprises it is possible to carry out effectively and operatively flexible profiles of any section in any quantities. Hydraulic profile bending has such significant advantages, as ease of operation and no need to use physical force in the bending process. As a disadvantage of such profilegibov it is possible to note only that, that for their work connection to an electric network is necessary.

Electric
Although this equipment is smaller, than hydraulic, it also belongs to the category of stationary. The use of electric profile benders makes it possible to make bent contours, exactly the corresponding drawings, and also to provide durability of finished products in places of bending. Electric profile bends are used to equip small businesses and workshops (that is, there, where there is no need to bend large cross-section profiles). There is also electromechanical equipment, which works in a semi-automatic mode under the control of the operator.

Manual
Such equipment for bending metal profiles is small in size, ease of operation and affordable price. It is the manual profile bender that can most often be found in private workshops or garages, where it is used for that, to make a bent profile from a metal profile or a pipe of small section if necessary. It should be borne in mind, that when using such a profile bender is almost impossible to control and even more so to get a bend, corresponding drawing. in addition, to bend the profile or pipe on the manual profile bender, will have to make significant physical effort. However, all these shortcomings are more than repaid by the affordable cost of manual profile bending, especially if you compare it with the price of hydraulic or electric machines.

Two versions of the simplest homemade profilegibov
Manual device for bending metal profiles of different cross-sections, as mentioned above, easy to make with your own hands. Profile bending can be useful in many everyday situations. Homemade device, by means of which it is possible to bend profiles of small section, will help you make your own, or repair structures, which use curved pipes or profiles at different angles.
Before you start making, it is necessary to be precisely defined with a design of a self-made profile bender and to execute at least the simplest drawing. Numerous photos and videos of such devices can help at this stage, which can be found online.
Let's start with the simplest designs, whose simplicity automatically means, that the functionality of such devices will be quite limited. But in some cases, the capabilities of such devices will suffice, and the simplicity and cheapness of their production will allow you to get started in a short time.
To make a device for bending pipes up to 20 mm, you don't even have to watch a training video. This profile bender has a very simple design, consisting of a concrete base and fixed in it steel pins, between which is flexible.

First of all, it is necessary to compact a small area of soil, cover it with rubble and level. Then this area should be filled with concrete mortar, which is prepared from a mixture of sand and cement (in the ratio 4:1). Before you start pouring the concrete solution, on the prepared basis it is necessary to strengthen some pieces of channels or pipes with a diameter not less 70 mm, At the same time it is necessary to fix them so, that with a surface of the basis they made an angle of 90 °, and the distance between the exposed metal segments was maintained close 4-5 div.
Inconspicuous in appearance, but quite workable homemade
After the concrete solution is poured, it must take some time. Across 2-3 days such a homemade pipe bender can already be used. The bent pipe or profile is placed between the pins protruding above the concrete base and bent to the desired angle. Which is convenient, such a pipe bender, made with his own hands, can be successfully used for bending stainless steel products.
If you need to bend pipes with a diameter of more 20 mm, then the homemade device for this will look a little more complicated. To make such a pipe bender, you also need to pour the concrete base and fix in it two metal wires of round section. The pins in this case will serve as axes for placing rollers on them, the dimensions of the grooves which must correspond to the diameter of the bending pipe. Use this profile bender as follows: the pipe is wound between the rollers and one end is securely fixed. The other end is attached to a manual or electric winch with a metal cable, which creates the necessary effort to bend.
Simple manual profile bender for bending of professional pipes on an angle of 90 °
There is another version of a simple device, which will allow you to manually bend the profile pipes at an angle of 90 °. Its design is quite clear from the photo, it is worth noting, that a low furrow on the bend will greatly simplify the work and reduce the effort required, which will need to be applied when bending profile pipes.
Drawings for making a homemade bending device
In order to make a quality and efficient pipe bender, it is best to use drawings (it can be drawn, and find on the Internet). As an example, consider the scheme of one of these devices, what you can do with your hands to bend pipes of square or rectangular cross section.
Drawing of a manual profile bender with three rollers
Simplified homemade version of the above drawing
The main elements of such a device are three rollers, two of which are used as supports, and the third is the working shaft. To facilitate bending of the pipe, the working roller of a profile bender deforms it gradually, until a bend with the required parameters is obtained. Gradual impact on the bending pipe is provided by, that the working shaft has some freewheeling, which is limited to special guides.

Appearance of the finished factory profile bender
The design of such a self-made pipe bender includes the following elements:
- plate thickness 5-8 mm;
- massive bearing plate;
- four corners long 30 cm, with shelf size 5 cm;
- auxiliary rollers.
Two corners are welded to the massive plate, which will act as guides, and by means of bolts fix auxiliary rollers. Two corners are welded to the lower part of the base to give it more rigidity. A plate with a hole is welded to the upper ends of the guide corners, the diameter of which must be larger, than the cross section of the screw, used to provide the necessary pressure on the bending pipe.

Option with a base of channels
Finally, it remains to install the working screw, the lower part of which is rigidly connected to the working roller, which forms the required bend of the pipe. For, that the processed pipe moved on auxiliary rollers, you can use manual (using a special handle) or electric drive.
When the profile bender will be assembled according to the drawing, it is possible to make trial flexibility, to adjust the operation of all its elements, and then use it for its intended purpose.
