Cold Bending Machine

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

1. Principle of uniform stress distribution across stages, with the entire roller line uniformly distributing stress, ensuring even wear and extending the roller's service life.

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, and two or even three tempering cycles are required after quenching to achieve the desired hardness.

3. The track arc section is the core part of the sliding track. After the initial forming of the arc, when bending the vertical edges in subsequent passes, the formed arc should be effectively constrained through the upper and lower rolling mills or cross wheels. Otherwise, the arc position of the material will definitely change during the stretching process, with R becoming triangular, the ball not reaching the bottom, resulting in noise from two-point contact. When R increases, it causes the track to vibrate, leading to blurred tracks during sliding track use, uneven force distribution, track deformation, and shortened lifespan.

4. Rolling stability issues often arise during production, where materials frequently experience lateral displacement within the rolling track. This is actually due to uneven force distribution on a single roller set; the left side exerts more force, causing the material to shift to the right; conversely, the right side exerts more force, causing the material to shift to the left.
