摘　　要：在汽车制造领域中,超过60%的金属制件需要使用冲压工艺加工成形。由于原材料性质、冲压模具状态和操作者人为因素等,可能会导致冲压件表面存在一定的质量缺陷。文章从汽车冲压件起皱、开裂、回弹等典型缺陷切入,深入探讨了制件表面质量缺陷检测方法,并提出了相应的改进措施。In the field of automobile manufacturing,more than 60%of metal parts need to be formed by stamping process.Due to the nature of raw materials,the state of stamping die,and the human factors of the operator,there may be some quality defects on the surface of stamping parts.In this paper,from the typical defects such as wrinkling,cracking and springback of automobile stamping parts,the detection methods of surface quality defects are discussed in depth,and corresponding improvement measures are put forward.
