Force principle and stability performance of Tracking Profile Cold Roll Forming Machine
Jul 11, 2018

The principle of average force of each track in the profile cold forming machine of the track profile, the average roller of the whole line is subjected to the average force and the wear is balanced, so that the service life of the roll can be effectively extended. The roll of the cold forming machine mainly adopts its resistance. Grinding performance, but the specific strength and hardness are contradictory. When heat treatment, the red hardness of C12MoV should be utilized. After quenching, two or even three times of tempering can reach the hardness.

 

The track arc part of the Tracking Profile Cold Roll Forming Machine is the core part of the slide rail. The arc position of the first few passes after the press forming, when the back pass is rolled up, the formed arc should be formed by the upper and lower rolls or the cross wheel. The effective tube bundle protection is carried out. 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, and the two points contact the noise. When the R becomes large, the matching rail is shaken. When the rail is used, the rail is used. The trajectory is blurred, the force is uneven, the slide rail is deformed, and the life is shortened.

 

The rolling stability problem of the cold-bending forming machine often encounters the problem that the material is yawed in the raceway during the production process. In fact, the single-group roller is asymmetrical, the left side is stressed, and the material is biased to the right. Pendulum; the right side is stressed, and the material is yawed to the left.
