摘　　要：在负间隙冲裁试验的基础上,找出冲裁力与负间隙值的关系,总结影响冲裁力的因素,提出阶梯型凸模负间隙冲裁的新方法。用铝板进行冲裁试验,得到剪切断面85%以上的光亮带冲裁件。Based on the experiment with negative clearance,the relation between the load of blanking and the variable of negative clearance has been indicated.The factors influencing the load of blanking have also been concluded.A new designed scalar male die with negative clearance has been presented.After proving experiment of such process by using aluminum,the stamping which has 85% smooth zone on the section profile has been obtained.
