The rolling stability problem of the cold bending forming machine is often encountered in the production of the material swaying left and right in the raceway. , the material is slanted to the left. The method of unbinding is as follows: the neutral layer in the deformation zone is accurately calculated, the material used in the deformation zone is accurately calculated, and the roller processing symmetry is good. The non-deformed area should not be pressed as much as possible (such as the bottom of the slide rail), and the gap between the upper and lower rollers should be consistent during assembly. Before the material is bitten, the guiding inclined opening should be set up according to the rolling state of the front track. Before the material is stably pressed, the material slides smoothly in the rolling. The problem of bending and twisting in the production of cold forming machine is mainly caused by unbalanced force, left and right forces are unbalanced, left and right bending, and up and down forces are unbalanced, resulting in distortion.
Cold bending machine is a new type of equipment for processing and manufacturing tunnel support steel arches, while cold bending forming machine is a machine that can be directly applied to assembly line production, with the same functions but different processing degrees.
The cold bending forming machine has the principle of average force in each pass, which can prolong the service life of the roll. In production, it should be designed with balanced force, accurate processing, and convenient installation and adjustment.
The cold bending machine ensures the strength of the material, improves the quality of the supporting steel arch, greatly improves the work efficiency, and the operation is simple and clear. Compared with the two, both have good working performance.
