Cold rolling forming is an important metal processing process widely used in fields such as automobiles, aerospace, electronics, and architecture. This process mainly involves applying external forces to cause plastic deformation of metal sheets at room temperature, thereby obtaining the required shape and performance of metal parts. This article will provide a detailed introduction to the process principle, application fields, and challenges faced by cold rolling forming.
1. Principles of Cold Rolling Forming Process
The cold rolling forming process mainly includes steps such as billet preparation, rolling, annealing, and finishing. In the blank preparation stage, metal raw materials are cut into the required size of the blank and surface treated to remove impurities and oxides. Then, during the rolling stage, external forces are applied to the billet through the rolling mill, causing it to undergo plastic deformation, thereby achieving the desired shape and size. During the annealing stage, internal stress is eliminated by heating and cooling, thereby improving the plasticity and toughness of the material. Finally, during the finishing stage, the formed parts are subjected to surface treatment and finishing to obtain qualified metal parts.
