摘要：

介绍了一款汽车内饰配件的多工位级进模设计。通过Dynaform板料分析软件对产品的冲压成形过程进行数值模拟分析，准确预测出该零件的成形缺陷。根据零件不同位置和角度的弯曲成形特征，本设计增设了两次成形中间过程，利用多次弯曲的方法，将各冲压成形区域在冲压方向上完全开放，使其不发生干涉，最终确定了包含冲裁、弯曲等工艺的11工位排样设计。通过企业生产验证，所设计的多工位级进模结构紧凑合理，产品成形质量稳定，生产效率高，可以满足大批量生产的需要。

It is introduced the multi-position progressive die design of auto interior parts. Then, the stamping forming process of part was numerically simulated by software Dynaform, and the defects of part were predicted accurately. According to the bending characteristics of parts at different positions and angles, two bending middle processes were added, and the 11-position layout design including blanking and bending were finally determined by multi-bending to make all stamping areas unrestricted in stamping directions so as to avoid interference. The actual production proves that the multi-position progressive die is compact and reasonable, and the quality of parts is stable with high efficiency to meet the needs of mass production.
