Roll Forming Machine Manufacturing Features

1, the average force principle of each pass, the average force of the whole line roller, wear balance, extend the service life of the roll.

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

3, the arc of the track is the core part of the slide rail, the arc position after the first few press forming, after the roll folding edge, to deal with the formed arc, through the upper and lower rollers or cross wheels, effective bundle protection, otherwise, the arc position of the material will change during the stretching process, R becomes smaller into a triangle, the steel ball is not in the end, two points contact produces noise, R becomes larger, When the rail is used, the track is fuzzy, the force is uneven, the rail is deformed, and the life is shortened.

4, rolling stability problems, often encountered in the production of materials in the raceway left and right swing, in fact, a single group of rollers by asymmetric, the left force is large, the material to the right swing; The force on the right side is large, and the material is tilted to the left.
