| 摘 要： | 当板材在受到冲压时,如果冲压工艺设计不合理,反弹会使板料的冲压结果不能符合图纸要求。文章用实验的方法探求无压边力的情况下板材的回弹问题。分别就材料性能、板料厚度、凸模圆角半径、凸凹模间隙、凹模跨度、摩擦系数等诸多因素对板料回弹的影响作出了分析。

| Abstract: | When the plate was stamped,if the stamping process design was unreasonable,the rebound would results can not meet the requirements of the drawings in the sheet metal stamping.Explore the rebound of sheet under no edge pressure with the experimental methods.Study the rebound in the various circumstances,for example,the thick of sheet,punch the gap between die,punch corner radius etc. |

| Keywords: | metal sheet stamping the thick of sheet clearance between punch and die punch corner radius friction U-bending springback |
