The main part of the cold bending forming equipment is the roll. For the design of the roll is very important, its design features are as follows: 1, cold bending forming equipment each pass average force principle, the roller average force, wear balance, increase the service life of the roll. 2. The material used for the roller is to use its wear resistance, but the specific strength and hardness are contradictory. The red hardness of C12MoV should be used during heat treatment. After quenching, the hardness can be reached by tempering twice to three times.

The main part of the cold bending forming equipment is the roll. For the design of the roll is very important, its design features are as follows:
1. The average force principle of each pass of the cold bending forming equipment, the average force of the roller, the wear balance, increase the service life of the roller.
2. The material used for the roller is to use its wear resistance, but the specific strength and hardness are contradictory. The red hardness of C12MoV should be used during heat treatment. After quenching, the hardness can be reached by tempering twice to three times.
3. The track arc part is the main part of the cold bending forming equipment. When the arc position after the first few passes of press forming is rolled and folded in the rear pass, the formed arc shall be handled and the tube bundle shall be protected by upper and lower rolls or horizontal wheels. Otherwise, the arc position of the material will change during the stretching process, and R will become smaller and become a triangle. When the shape R becomes larger, the matching rail will shake, the force will be uneven, the slide rail will deform, and the service life will be reduced.
4. The problem of rolling stability. In production, the problem of left and right deflection of materials in the raceway is often encountered. In fact, a single group of rollers are asymmetrical, with large force on the left and the material swings to the right. The force on the right is large, and the material swings to the left.
