用冷冲压将型材加工成各种制件的方法是一种能够节约材料、节省能源,又能显著地提高生产效率的先进工艺。因而被广泛地应用于汽车、电器、日用五金等行业。一、异形型材切断和冲裁的特点所谓异形型材是指型材中同一截面、不同方向上形状和厚度各异的型材。汽车启动机用磁极型钢截面图。切断这种型材有如下一些特点: Cold stamping profiles into various parts of the method is to save material, save energy, but also significantly improve the production efficiency of advanced technology. It is widely used in automobiles, appliances, household hardware and other industries. First, the profile cutting and blanking the characteristics of profiles The so-called profiled profile is the same profile in the section, the shape and thickness of different shapes in different directions. Pole section steel for automobile starter. Cut off this profile has the following features:
