The core part of cold roll forming equipment - roll. It is the soul of cold roll forming, the design of roll is extremely important, the design characteristic of roll is as follows:
1. The average stress principle of the cold roll forming machine , the average force of the roller, the wear balance, and the service life of the roller.
2. cold bending forming equipment of the roll using 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 times or even three times to reach the hardness.
3. arc track position is the core parts of the slide, before several pressing, arc, in the following passes rolling folding vertical edge, to deal with arc forming, through the under roller or transverse wheel, effective protection of the bundle, otherwise, the material in the tensile process arc position will change and R become a small triangle, steel ball and not in the end, two point contact noise, R becomes larger, with rail swing, slide when using fuzzy trajectory, uneven stress and deformation of the slide and shortened life expectancy.
4. rolling stability problems, the production of materials often encountered in the rolling road around the problem, in fact, a single set of rollers by asymmetric, the left side of the force is large, the material to the right side of the right side, the right side of the force, the material to the left side of the.
