采用钢板、钢带、钢管冷冲压力加工成型,是现代工业生产中的一个重要组成部分。我厂就有50%的零部件是用钢板、钢带、钢管冷冲压力加工成型的。但是,冲裂是冷冲压力加工时最易出现的一种疵病,它直接影响着产品质量,甚至造成成批零件报废。本文将介绍冲裂的影响因素,及其特征和防止,供同行参考。一、由于材料表面缺陷导致冲裂1.划痕:由轧制设备的某些零件与轧件摩擦而产生,如轧槽内的毛刺,易使轧件表面产生连续的划
The use of steel, steel, cold stamping steel processing pressure forming, is an important part of modern industrial production. I plant 50% of the parts are steel, steel, steel cold stamping processing molding. However, the cracking is the most prone to cold stamping process flaws, it directly affects the quality of products, and even caused the bulk of scrapped parts. This article will introduce the impact of factors, and its characteristics and prevention, for peer reference. First, due to surface defects caused by material cracking 1.
