摘　　要：汽车车身冲压零件的质量问题种类较多,深度较深的立壁位置容易出现起皱缺陷,较难解决,而且会对整车的质量造成影响,通过采用在冲压零件立壁位置增加台阶造型的方法,断开了板料流动过程中起皱扩展的整体趋势,减缓了该类起皱问题的产生,对于提高冲压零件及整车的质量品质具有指导作用。There are many quality problems on the automobile body stamping parts,while wrinkling on the deep wall is hard to solve and affect the vehicle quality.By trying to increase steps on the wall,the overall trend of fold to expand in the flowing process of sheet metal was controlled,and the wrinkling problems were controlled,which improved the quality of stamping parts.
