Design of Roll Table Times of Cold Forming Machine
Working in the cold bending industry, customers often ask the question of the number of passes of the cold bending forming machine. In fact, there is no absolute answer to this question. Each roll designer has his own set of design schemes, and the forming ideas are different. At the same time, it will also be affected by many other factors. For example, fierce market competition may cause cold-bending machine manufacturers to reduce the number of passes as much as possible, and the material and thickness of the formed profile will affect the number of passes of the cold-bending forming machine. Below we briefly introduce what are the specific factors that affect the number of Dao?

1. The thickness of the material will affect the number of passes. Regarding the problem that the thickness of the material affects the number of rolls of the cold roll forming machine, it seems that there is a wrong kind of difficulty in the market now. Many people believe that the thicker the material, the more passes are required. But from the perspective of foreign cold-formed technology, this argument is actually relative. If the design of the cold roll forming machine has a high configuration, such as wall panels, shafts, roll materials, motors and other configurations, on the contrary, the thicker the material, the number of passes required will be reduced accordingly. If the equipment configuration is not high, more passes should be used to reduce the force that each group bears. For thin materials, if you increase the number of passes, you can reduce the chance of waves. Or the surface requirements are high, and there can be no scars, and the number of passes can be increased to solve better.
2. The material quality affects the number of passes. The higher the hardness of the material, the more passes are required. If the thick stainless steel profile is cold-formed, more passes are required.
3. The cost of the machine will affect the number of passes. For manufacturers of cold roll forming machines, in order to control production costs, the number of passes will also be reduced as much as possible. Therefore, in many cases, if the unit price of the signed contract is lower, the manufacturer will suggest fewer passes.
4. The experience of the designer of the cold-formed roll will affect the number of passes. The designer plays a decisive role in the number of passes, generally based on the customer’s experience, or the degree of conservativeness will affect the number of passes. Some designers may be conservative and increase the number of passes so that when a problem occurs, there will be more room for modification.
