Advantages and mechanical properties of the tracking profile cold roll forming machine
Jan 17, 2019

When the tracking profile cold roll forming machine is used, it is mainly used to form a multi-pass forming roll which is sequentially arranged, and the metal plate such as a coil material and a strip is continuously bent laterally to form a plastic working process for a specific section profile.

Advantages of the use of  tracking profile cold roll forming machine

1. The principle of average force of each pass, the average roller of the whole line is stressed, the wear is balanced, and the service life of the roll is extended.

2. The roller adopts C12MoV material to utilize its wear resistance, but the specific strength and hardness are contradictory. When heat treatment, the red hardness of C12MoV should be utilized, and after quenching, two or even three times of tempering can reach the hardness.

3. The arc part of the track is the core part of the slide rail. The arc position after the first few press forming, when the vertical pass is rolled up, the formed arc should be formed, and the effective tube bundle protection is carried out by the upper and lower rolls or the cross wheel. Otherwise, the arc position of the material will change during the stretching process, R becomes smaller and becomes a triangle, the steel ball is not in the end, the two points contact the noise, and when the R becomes large, the coordination rail is swayed, and the track is blurred when used. Uneven force, deformation of the slide rail and shortened life.

4. Rolling stability problem, the problem of material yaw in the raceway is often encountered in production. In fact, the single set of rollers is asymmetrical, the left side is stressed, the material is yawed to the right; the right side is strong, the material deflection to the left.
