摘　　要：介绍了降低冲压力的方法与措施 ,叙述了温差拉伸法和阶梯斜刃冲裁法 ,同时指出了冲压资料中斜刃冲裁力计算公式的适用范围 。The methods and measures to lowering the pressing force were introduced. The thermal_differential drawing method and the step beveled_edge blanking method were stated. The applying range of the formula for calculating the beveled_edge blanking force in the reference books on pressing was pointed out, which is of reference value to solving actual production problems.

关 键 词：冲压力 加热 温差拉伸法 阶梯斜刃冲裁法
