Cold - bending machinery and equipment design and manufacturing characteristics

1, orbit arc parts is slippery course core parts, the first few after moulding of circular arc, the back pass rolling vertical edge, deal with established arc, through the roll up and down, or cross, effectively control protection, otherwise, the material in the process of drawing arc will change, R has shrunk as triangles, steel ball is not in the end, two contact produce noise, when R is bigger, shaking with rail, slide rail track when using fuzzy, uneven, slide rail deformation, shorten life.

2, the average force principle of each track, the average force of the entire roller, wear balance, extend the roll service life.

3, rolling stability, production often encountered in the material in the raceway left and right skew problem, in fact, a single set of rollers suffer from asymmetry, the left side of the force, the material to the right skew problem;The force on the right side is high, and the material swings to the left.

4, roller using C12MoV material is to use its wear resistance, but the specific strength and hardness is contradictory, heat treatment to use the red C12MoV hard, quenching, two or even three times of temper to achieve hardness.
