  Taking experiment on the Q235, copper, in the condition of positive clearance is 0.04 mm and width of stepped edges is 1.2 mm the negative clearance between 30% and 40% of the thickness depend on the finite element method conclusion.

  根据有限元分析结果,对模具正间隙、凸模刃口阶梯高度分别取0.04 mm、1.2 mm,相对负间隙在10%~30%范围内变化的不同情况进行了实验研究。
