Design and Manufacture Characteristics of Cold Roll Forming Machine

The design and manufacture characteristics of cold roll forming machine are as follows:
1. The arc position of the track is the core part of the slide track. The arc position after the first several pressing passes should be protected effectively by the upper and lower rolls or the horizontal wheels when the vertical edge is folded in the back passes. Otherwise, the arc position of the material will change during the stretching process. R will become a triangle, the steel beads will not reach the bottom, the noise will be produced when the two points contact, and when R becomes larger, it will be matched. Sliding occurs when the sliding track is in use. The track is blurred, the force is uneven, the sliding track is deformed, and the service life is shortened.


2. Following the principle of average force on each pass, the roller of the whole line is forced on average to balance wear and prolong the service life of the roll.

3. The problem of rolling stability is often encountered in the production of materials in the raceway, which is actually due to the asymmetry of a single group of rollers, which makes the force on the left side large, the material yaw to the right side; the force on the right side is large, and the material yaw to the left side.

4. The roll used C12MoV material is made use of its wear resistance, but the specific strength and hardness are contradictory. The red hardness of C12MoV should be used in heat treatment. After quenching, hardness can be achieved only by twice or even three tempering.www.ybtformingmachine.com
