摘要
详细分析了冲压制件的冲压缺陷(膨凸、回弹):V形弯曲时引起直边弯曲、扭曲、翘曲、弯曲裂纹、垂直度不好、形状精度不好、折边形状左右不对称等问题,并给出了解决措施。
The punching defects （bulgy protruding, springback） of punched parts are analyzed in detail, such as the problems caused during V-shaped bending, the vertical border bend, distortion, twist, bending crack, poor perpendicularity degree, poor shape precision, unsymmetrical hem shape in right and left side, and so on, the solving steps are given out.
