Cold-formed Machine Design And Manufacturing Features
Jan 31, 2018

Cold-formed machine design and manufacturing features:

1, the principle of the average force of every pass, the average force across the board roller, wear balance, extend the life of the roll.

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

3, the track arc is the core part of the track, the first few Road after forming the arc-shaped bit, rolling pass in the next pass, the response has been formed arc, through the upper and lower roll or wheel, effective protection of the bundle , Otherwise, the material in the drawing process will change the arc position, R becomes smaller triangle, the ball is not in the end, the two contacts produce noise, R becomes larger, with the rail to produce shaking, the track when using the track fuzzy, by Uneven power, slide deformation, shorten life expectancy.

4, Rolling stability problems, often encountered in the production of materials in the raceway left and right side of the problem, in fact, is a single roller by the asymmetric, the left force, the material to the right side of the deflection; the right force, material Swing to the left
