The Design of Roller in Metal Roll Forming Machine and Its Matching Straightening Mechanism

1. The design of the roll in the metal roll forming machine and its supporting straightening mechanism


The roll in the metal roll forming machine is a very important part of it. Its design and manufacturing features are: each pass should be evenly stressed in order to be able to wear evenly, thereby prolonging the service life of the roll. Generally, the roll is made of C12MoV material, because this material has good wear resistance, but it is necessary to pay attention to the hardness and strength, so it must be handled well.


The upper and lower rolls or horizontal wheels should be protected by effective tube bundles, otherwise problems are prone to occur during use. For example, the track will be blurred and deformed, and the force will be uneven, which will shorten its service life. In the rolling process of the metal roll forming machine, the rolling stability must be considered.


2. The straightening mechanism should be used at the end of the metal roll forming machine


If the material swings left and right in the raceway, then we have to take corresponding measures. For example, when assembling, keep the gap between the roller areas consistent. And before the material bites in, a guide bevel can be set to avoid this problem. In the production process, if there is a bending and twisting phenomenon, the main reason is the unbalanced force, so we must balance the force during the design so that the processing can be accurate.


A basic principle of the metal roll forming machine process is: the strip is bent in a straight line along the longitudinal direction. However, the pressure generated during the bending deformation is combined with the residual stress in the strip, and it is often the strip that deviates from the equipment. In order to solve these problems, a straightening mechanism should be used at the end of the metal roll forming machine.


The basic principle of the straightening mechanism is to deform the profile with defects such as side bending and warping through the correcting mechanism with sufficient pressure in the opposite direction. If the amount of deformation in the opposite direction is appropriate, the profile can be completely straightened after rebounding. If the profile is twisted and deformed in a certain direction, the straightening mechanism rotates the profile in the opposite direction in order to produce plastic deformation. If the angle of rotation is appropriate, the profile will no longer be twisted after rebounding.
