Structural design of roller straightening machine and its roller group arrangement
- Oct 27, 2018 -

In the past, most of the straightening machines were carried out by using a plurality of rolling rollers in the upper and lower rows. The speed reducer was driven by a complicated gear transmission, which was complicated in structure, inconvenient to maintain, expensive, and in the process of straightening the rollers. The surface of the metal being straightened is often damaged. To this end, a new type of roller straightener was developed.


The utility model has the advantages of simple structure, no complicated reducer and gear transmission mechanism, convenient maintenance, and does not damage the metal surface during the straightening process. It is designed in such a way that in the upper part of the frame made of angle steel, two bearing housings support a regulating cylinder, which is composed of two parallel steel plates with a certain gap in the middle and a hollow hole in the middle. The shafts are connected together. There are a plurality of straightening roller groups on the upper and lower sides of the adjusting cylinder, the axis of which is at an angle to the axis line of the regulating cylinder, and a pulley is arranged at one end of the bearing housing extending from the adjusting cylinder.


The roller group structure of the roller straightening machine is arranged on the wire regulating cylinder, and two parallel positioning plates are fixed, and one end of the L-shaped bracket is fixed by the pin, and the center of the bracket is loaded with the roller through the pin shaft and the nut, the L-shaped bracket The other end is supported by a spring that is guided by a fastening bolt, and the upper portion is fixed by a compression nut.


In order to facilitate the operation of the roller straightening machine, the angle between the central axis of the roller set and the central axis of the adjusting drum is preferably 45°-50°, and the connecting between the center of the roller on the same side of the upper and lower sides and the adjusting cylinder The axes of the axes are parallel on the same horizontal plane, and the number of roller groups on the upper and lower sides cannot be less than 2 and 3.
