The main part of the Cold Roll Forming Equipment is the rolls. The design of
the rolls is very important, and its design features are as follows:
Cold Roll Forming Equipment
1. The principle of average force of each pass of the cold-bending forming equipment, the average force of the roller, the wear balance, and the service life of the roll.
2. The material used in the roll is to use its wear resistance, but the specific strength and hardness are contradictory. When heat treatment, the red hardness of C12MoV should be utilized. After quenching, the hardness can be achieved by tempering twice to three times.
3. The arc part of the track is the main part of the cold-bending forming equipment. The arc position of the first few press-formed moldings should be protected by the upper and lower rolls or the horizontal wheel when the rear side is rolled and folded. Tube bundle. Otherwise, the arc position of the material changes during the stretching process, and R becomes smaller and becomes a triangle. When the shape R becomes larger, the rail is swayed, the force is uneven, the rail is deformed, and the service life is reduced.
4. Rolling stability problem, the production often encounters the problem of material yaw in the raceway, in fact, the single set of rollers is asymmetrical, the left side is strong, the material is yaw to the right; the right side is strong, the material Deflection to the left.
