摘　　要：为了降低冲压模具开发成本,以某车型后地板为研究对象,分析了制件结构特点和冲压工艺性。通过将修边与落料集成,以及采用“成形+翻边”集成工艺代替“拉伸+翻边”工艺,实现了后地板冲压工艺方案的两工序化,获得了外观成形质量良好、精度合格的制件。实践证明,两工序冲压工艺方案不影响制件品质并可有效缩短冲压模具工序数量,从而能节约冲压模具以及制件生产成本,提高生产效率,降低模具开发费用,取得了明显的经济及环境效益。In order to reduce the development cost of stamping die,the rear floor of a certain vehicle is used as the research object,and the structural characteristics and stamping process of the product are analysed.It has been proven that the two-process stamping solution does not affect the quality of the parts and can effectively shorten the number of stamping die processes,thus saving stamping die and part production costs,improving production efficiency,reducing die development costs and achieving obvious economic and environmental benefits.
