We assemble the rollers for the profile pipe by our own hands

Very often in a household, when carrying out various repairs, it is required to bend a piece of pipe in a special way, and in this case it is necessary to think about how to assemble the rollers for the profile pipe yourself.

This special machine, which with minimal effort is able to cope with almost any pipe, must have in its arsenal every caring owner.

Of course, it's easiest to get professional rollers in a specialized store, but not everyone has extra money for this device.

Ordinary rollers are a device that has a special lever, driving several metal shafts, passing through which the metal workpiece acquires the necessary bent shape.

To do the rollers yourself at home, you need to have the relevant drawings on hand and understand the principle of work.

Homemade rollers for bending metal blanks will have a decent quality and good performance if the technology of their assembly is strictly observed.

Features and types of rolls

The most common are rolls with a manual drive. This universal device, as a rule, has compact dimensions and comparatively low weight.

The wizard should not have problems with their placement in his workshop.

Manual rollers, designed for bending various metal blanks, do not have an electric drive, which means they can work in almost any conditions.

In most cases, such a hand-held device consists of a metal solid frame, as well as feeding rolls, which are made in the form of small cylinders.

They are connected together by a chain transmission, which leads them into motion if necessary. In addition, the rollers have small clamps.

In order for the rollers to be able to produce the necessary deformation of the workpiece, they are additionally equipped with a special transfer tube.

In order to perform the necessary work on such a device, the wizard must exert a certain physical effort, so in large plants they are not used.

It is most convenient to work on rollers that are equipped with an electric drive. The metal blank, which must be bent, is pulled through the working area with a powerful electric motor.

In appearance they remotely resemble manual models, the difference is that in a special place an electric motor is mounted.

Electric rollers are most often used in large plants.

Another type of rollers for bending of preforms from metal, which is used in industrial plants, has a special hydraulic drive.

They are quite impressive in size and have a large capacity, which allows you to work with virtually any type of workpiece.

Hydraulic driven rollers can perform a large amount of necessary work in a short period of time.

Features of home-made rolls

Practice shows that it is not necessary for the home master to have on hand professional rollers equipped with a hydraulic drive or an electric motor.

Such devices have not only a fairly complex design, but also require for self-assembly the availability of expensive components at hand.

In most cases, the household is faced with the need to deform various metal products extremely rarely.

Therefore, it is enough for the home master to have a manual option at hand, which can also be freely assembled by hand.

All that is required for this is a certain set of components, a workstation and the corresponding tool.

To ensure that the device collected at home, could easily cope with its task for the purpose and served the owner for many years, it is necessary to comply with certain rules when assembling.

First of all, all the components for the device should be selected as high-quality and durable, without any defects. Very often all the necessary components can be found in your own farm.

In addition, before starting the assembly work, it is recommended to study the relevant drawings, which will give a complete idea of ​​the principle of operation of manual types of devices.

If exactly all stages of work are observed, and only high-quality components are used, the bending device will not only be reliable, but also durable.

Assembly stages

Start assembling the self-made roller from the frame. It should turn out as strong and tough as possible. For its manufacture it is better to take tubular metal, however, the channel of the corresponding section also approaches.

The deforming part of the carcass should be made U-shaped, and on its upper part it is necessary to strengthen the nut by welding.

In doing this work, you should use a clamp, which must necessarily have a thread.

After this, the nut must be screwed into the appropriate pin, the diameter of which must match the size.

At the end of the nut, it will be necessary, using welding, to strengthen the round metal heel. For convenience, it will be possible to mount a hydraulic jack.

It needs to be fixed in the lower part of the frame frame and thus the deformation will be effected by the incoming force on the feed rolls located in the upper part.

The next step is to make a reliable and functional feeder. To do this, take a metal chain. A metal chain from an old bicycle will do.

One of the asterisks will need to be strengthened on the deforming shaft, and the second - on the slave. After this, it is necessary to carefully tighten the installed chain and only after that you can try to turn the corresponding handle.

In order to individually cut the required rolls, you can use ordinary alloy steel. The finished rollers will necessarily have to be hardened.

It should be remembered that the rolls thus obtained, by strength, must significantly exceed the material that will subsequently be processed on the machine.

The rollers are attached to the device through the rolling bearings. To fix them it is necessary as much as possible reliably so that they do not jump off and do not bend when working the roller.

Recommendations and tips

In order to assemble a device by yourself, with which you can easily make a deformation of the profile pipe, you do not need to have any professional knowledge.

Any home master who has little skills in construction, can do it in a short time.

The main thing in this case is to have at hand all the necessary material and tools. If the device is assembled from quality components and by all the rules, it will be possible to solve absolutely any problems, even the most complex ones.

When making this equipment, radial adjustment must be provided. This will, if necessary, quickly change the gap between the working mechanisms of the device.

It is also advisable to think about the possibility to adjust the angular clearance, which will further simplify the work on the roll.

When working on a roll, observe the safety rules. In addition, the device itself should not be dangerous.

When manufacturing the device, it is necessary to protect all working mechanisms as much as possible, thereby preventing all possible risks of injury.

The self-made roller in certain individual cases can surpass the factory products in its performance characteristics.
