Cold Bending Molding Die Factory

Cold Roll Forming Machine, Ball Bearing Guided Rail Machine Roller Design and Manufacturing Features:

1. The principle of average force distribution across each pass, with uniform force distribution across all roller lines, ensures even wear and extends the lifespan of rolling mill rolls.

2. The use of C12MoV material for rolling mill rolls takes advantage of its wear resistance, but there is a contradiction between its strength and hardness. During heat treatment, the red hardness of C12MoV must be utilized. After quenching, hardness can only be achieved through two or even three tempering cycles.

3. The track arc section is the core part of the sliding track. After the initial pressing and forming of the arc, during subsequent rolling and bending to create the vertical edge, the formed arc should be effectively restrained using the upper and lower rolling mills or cross wheels. Otherwise, the arc position will change during the stretching process, the radius (R) will become triangular, the ball will not reach the bottom, resulting in noise from the contact points. As R increases, it causes the track to vibrate, making the sliding track's path unclear during use, unevenly distributed forces, deforming the track, and shortening its lifespan.

4. Rolling stability issues: During production, we frequently encounter problems with materials swinging left or right in the rolling track. This is actually due to uneven distribution of force on a single roller set; more force on the left causes the material to swing to the right, and more force on the right causes the material to swing to the left.
