Solution to the distortion problem of the cold roll forming machine
In the production process of cold-formed forming machines, the distortion of the produced products is a frequently encountered problem. These problems plague some newly-started installation and commissioning masters, or equipment purchasers who arrive at the factory. After a period of production, the produced profiles will be produced. It starts to fail and appears to be distorted. So how should the distortion problem of the cold roll forming machine be solved?
Twisting phenomenon of cold roll forming machine
1. The profile distortion produced by the cold bending machine is related to the installation and debugging of the equipment. When the cold bending machine is installed at the beginning, the installation of the roll is an important part of testing the level of the installation master. If the installation is unqualified, the installation of the roll is not In a straight line, no matter how the adjustment is made, there is no way to solve it, and the roll can only be reinstalled. This situation is easy for the manufacturer to solve when the machine has not left the factory, but if the machine has been sent to the purchaser, it will be difficult to deal with it. Or after the equipment has been produced for a period of time, the rolls will move in position. If this is the case, the only thing to do is to reinstall the rolls and adjust them directly.
2. The straightening structure of the cold roll forming machine is installed. After the equipment is formed, the equipment generally has different degrees of distortion. In this case, the straightening device after forming must be used to correct the up and down, left and right distortions. effect.
3. Distortion caused by unreasonable roll design of the cold bending forming machine. In this case, the roll can only be modified again. If the gap is unreasonable, the roll should be re-finished to achieve a reasonable roll gap.
