拉深系数与冲压力关系的分析

Analysis of Relations Between Coefficient of Pulling Depth and Stamping Force

对通过试验机获取的实测拉深冲压力行程曲线进行分析 ,找出拉深系数与拉深冲压力之间更深层内在联系 ,归纳出不同拉深系数值、不同拉深次数下拉深冲压力随凸模行程的不同变化规律 ,为使拉深工艺设计更趋于合理、完善提供了参考依据。

It finds out the inner deep relations between Coefficient of pulling depth and stamping force. Then sums up different value of coefficient of pulling depth, different changing law following terrace die for stamping force of pulling under different number of pulling (depth). Provides referent data to improve the designs of pulling depth.
