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。
Through the testing machine to obtain the measured drawing tension stroke curve is analyzed to find the deep drawing coefficient between the drawing force and drawing a deeper intrinsic relationship between the induction of different drawing coefficient values, Different variation of the punch stroke, in order to make the drawing process design more reasonable, perfect provides a reference.
