摘　　要： 分析了冲裁过程中断面光亮带、断裂带、圆角和毛刺形成阶段,运用塑性增量理论、应力莫尔圆方法和粘着磨损法则,来分析影响光亮带和断裂带、圆角和毛刺形成的力学因素,得出确定模具合理间隙值是获得高质量冲裁件的关键因素。 The forming stage of section light zone, fraction zone, fillet, and burr during the blanking process has been analyzed in the text. The mechanical factors which influence the forming of light zone, fraction zone, fillet, and burr have been analyzed by use of plasticity incremental theory, Mohr circle method and adhesive wear law. It is obtained that the determination of proper tool gap is the key factor in improving the quality of blanking parts.
