The so-called rollers used for working with metal blanks are a special class machine, through which you can get bent profiles of any degree of complexity.
The main functional unit of such a mechanism is the rolls, made in the form of rotating cylinders, in the gap between which the initial billet is formed. Different models of rollers have a number of such cylinders (usually they are installed from 3 to 5 pieces).
Several models of mechanisms of this class are known differing both in the type of drive and in their performance. These devices are:
Hydraulic driven rollers
Manual rolls for a profile pipe do it yourself hands-on, practical in use and have a relatively small size. A good owner, who decides to purchase this tool, most likely will not have problems with its installation or maintenance. Rollers usually consist of the following parts:
The hand-held device is equipped with a special tube that serves as a guide for the bend workpiece. A person handling such a mechanism must possess "non-human" physical strength. That is why such machines are most suitable for working with small pipe products produced in minimal quantities.
Electric analogs have a significantly higher performance because the actuator pulling the tube through the rolls is driven by an electric motor. The effectiveness of the automatic broach is significantly increased, so that such equipment is used very often in industries focused on the production of large quantities of products.
As for the mechanisms with hydraulic drive, they differ from all the above devices with increased power and can be classified as capital industrial equipment.
In the event that you decided to do self-repair work - without the so-called "pipe bender" you are unlikely to manage. This statement applies mainly to those household operations that are directly related to the use of bent pipe profiles.
Self assembly of rollers is possible in principle; and the main thing here is to follow certain instructions. In addition, the procedure of installation of mechanisms will require from the performer certain skills in the conduct of mechanical work and not all beginners will be able to.
Before the start of assembly procedures, you should prepare all components, as which it is allowed to use various spare parts, which are always available in almost every careful owner.
Making the rollers drawing
The order of the stage-by-stage assembly of this household mechanism is approximately as follows:
Parts kit for rollers
The finished roll mechanism must be provided the so-called radial adjustment, through which you can change the size of the gap between the work rolls. In addition, it was not bad to foresee the possibility of making an angular (axial) adjustment.
