What Is Cold Roll Forming Machine

Cold Roll Forming Machine is a kind of machine which is used to make the coil, strip and other metal plate continuously bent transversely, so as to make the plastic processing technology of the special section profile.

Design and manufacturing features:

1, the average force principle of each pass, the average load on the whole roller, the wear balance, and prolong the service life of the roller.

2, roll C12MoV material is the use of its wear resistance, but the specific strength and hardness is contradictory, heat treatment to use C12MoV red hardness, after quenching, two or even three tempering to achieve hardness.

3, the arc part is the core part of rail track, the previous arc pressing after, after pass folded edge when dealing with arc shaped, the upper and lower roll or transverse wheel, or for effective protection, material in the bundle, tensile process of arc bit will change, R a small triangle, the ball is not in the end, two contact noise, R becomes large, with rail swing, slide when using fuzzy trajectory, uneven stress and deformation of the slide, shorten life.

4, the rolling stability of the material in the raceway around the swing in the problems often encountered in the production, is actually a single group of wheels under asymmetric left force, material to the right swing; right force, material to the left swing
