Make rollers for the profile pipe with your own hands, using drawings and knowledge of the principle of operation of this useful device, quite real. Using such a device, having high versatility, you will be able to independently make from professional pipes bent designs of any degree of complexity.
Rolling of profile pipes for a canopy on the self-made machine
The main working bodies of the rollers, having a mechanical effect on the processed profile pipe, there are rotating rolls, the number of which may vary from 3 to 5 things. In a gleam between rolls plastic deformation of a professional pipe also occurs.
Types of devices with rotating rollers
Rolling of a profile pipe, resulting in a change in its initial configuration, can be performed on equipment of various designs. Such devices for rolling of a profile pipe can differ on type of the used drive and on the main technical characteristics. So, rolling rollers may have:
- manual drive (the use of such devices for rolling profile pipes requires considerable physical effort);
- electric drive;
- hydraulic drive mechanism.
Manual rolling rollers are just a prototype for self-manufacturing machine
The simplest (and, in accordance, inexpensive) devices, by means of which carry out rolling of a profile pipe, there are manual profile bends. Along with their reliability and ease of use, they have a number of significant advantages. The design of the profile bender manual consists of the following elements:
- massive bed, which serves as a reliable basis for the entire structure;
- rollers, which perform the supply and reception functions (these structural elements, by means of which rolling is performed, are connected by a chain transmission);
- set of clamping mechanisms (strubcin), designed for fixing pipes of different sizes.
The main parts of the rollers
Such a rolling machine, has a simple design, also equipped with a special pipe, which acts as a guide for the bending workpiece. It should be borne in mind, that the use of such a machine requires the performer to make significant physical effort. in addition, this device does not allow to carry out rolling with high productivity and is most often applied to simple works in house conditions.. That is why the structural scheme of this machine is used for this purpose, to make a profile bender with your own hands. Such simple on a design profilegib allows to carry out rolling of profile pipes qualitatively and with high efficiency..
Electric machine for rolling profile pipes, even made yourself, provides higher productivity of technological operation. This is due to the fact, that the electric drive is responsible for performing the main operation - pulling the professional pipe through the rollers, whose power can be quite large. That is why electric rollers for profile pipes, which can be done with your own hands, using drawings, used as small organizations or craftsmen, and manufacturing enterprises.
The machine can be equipped with an electric drive later, the main thing is to take this into account first and develop a fairly powerful design
But, Of course, the hydraulic profile bending machine differs in the highest power, which is quite difficult to make with your own hands. Devices of this type, are intended for rolling of profile pipes, used mainly in industrial enterprises, where to carry out such technological operation is necessary with high productivity.
Homemade devices for rolling pipes
Without such a device, as a device for rolling professional pipes, practically can not do in those situations, when you decide to do the repair yourself, in the performance of which will have to deal with bent pipes. To do this, you can buy a serial device for this purpose or use a homemade profile bender, whose design is not very complex. The question of that, how to make a profile bender, it makes sense to put more for that reason, that serial models are quite expensive, therefore their acquisition (especially if they are needed only for home repairs) not always appropriate.
Approximate dimensions of homemade rollers
In order to make high-quality homemade rollers, you can study theoretical information, watch videos on this topic, but the main thing is to follow the recommendations of those, who have already achieved good results in resolving this issue. Of course, to make your own roller, it is necessary to have not only the relevant knowledge, but also certain skills in the manufacture and use of various technical devices.
Kinematic scheme of the machine
Homemade rollers can be made even from improvised materials, which are almost always in any garage or home workshop. The efficiency of such rollers, if they are made taking into account all the recommendations, will be much lower, than in models, mass-produced.

How to make a profile bender yourself
To make a profile bending machine with your own hands, the following sequence of actions must be followed.
- First of all the basis or a bed is made, for which you can use large diameter pipes or steel channels.
- Serious attention should be paid to the manufacture of the vertical support of the machine, the material for which can be a U-shaped profile. It is in the upper part of such a support, which must be highly reliable, the deforming pipe knot - the roller mechanism is established. For installation of a vertical support, the lower part of which is securely fixed under the frame, you need a clamp of the appropriate size. With this method of mounting the vertical support deformation force, which is made on a bent profile pipe, will be evenly distributed on the two feed rollers.
- To rotate the feed rollers, use a chain drive, which can be collected, using a chain and sprockets from an old bicycle. Asterisks, which in their geometric parameters must strictly correspond to the characteristics of the circuit used, fixed on the feed and driven shafts. When installing the chain feeder for your home-made machine, you should ensure a good chain tension and only then proceed to fix the handle of the feeder. Naturally, that the drive mechanism of your machine for rolling professional pipes should provide easy rotation of the feed and driven shafts.
- The most homemade rollers, which will put pressure on the bent profile pipe and thus perceive the main load during operation of the machine, best made of steel, which has passed the hardening procedure.
The whole process of making a manual profile bender is shown in detail in the photos below.
To make a rolling machine for profile pipes, made with his own hands, possessed high versatility and could be used for processing of products of the different size, in its design it is necessary to provide for the possibility of performing radial adjustment. This important option allows you to change the size of the gap between the work rolls. To make your homemade rollers even more functional, can be provided in their design the ability to perform and angular or, as it is called, axial adjustment.
Homemade devices for profile bending of rolled pipe, made according to universal schemes, can be further upgraded, if necessary. Example, they can be electrically driven or fitted with more work rolls.
The design of the machine can be simpler, if you use a hydraulic jack, as shown in the video below.
