摘　　要：为解决产品搭边、料带排样、工艺顺序等难点问题,介绍了汽车连接片多工位级进模的设计过程,并在分析产品结构特征的基础上,根据多工位级进模的设计要求,给出了解决方案。设计过程中运用Dynaform软件对弯曲、拉深等重点工艺过程进行了板料成形数值模拟,预测了不同成形方案下产品的成形质量,最终确定了一套10工位的级进模结构。该套模具包含冲裁、弯曲、局部拉深等冲压工艺,料带采用单斜排的排样方式,由自动送料机构送入模具本体,经多组弹性托料块承载向前输送。成形过程中兼顾了产品性能,且提高了材料利用率,材料利用率最高可达51.5%。经过实际生产验证,该套模具使用过程中运行平稳,所得冲压产品质量满足设计要求,级进模设计合理。In order to solve the difficult problems of product edging, strip layout and process sequence, the design process of the multi-position progressive die for automobile connecting piece was introduced, and based on the analysis of product structure characteristics, the solution schemes were provided according to the design requirements of the multi-position progressive die. Then, during the design process, the key processes of bending and drawing for sheet metal forming were numerical simulated by Dynaform software, and the forming quality of products under different forming schemes was predicted. Finally, the ten-position progressive die structure was confirmed, which including blanking, bending, local drawing and other stamping processes. Furthermore, the layout mode of single oblique arrangement for strip was adopted, which was sent to the die by automatic feeding mechanism and transported forward through the multi-group elastic support blocks. The forming process not only ensured the product performance, but also improved the utilization rate of materials, and the material utilization rate reached up to 51.5%. Actual production verification shows that the die performance is stable during the use process, the quality of stamping products obtained meet the design requirement, and the progressive die design is reasonable.
