摘要
文章介绍了汽车内板件在冲压成形中出现的开裂问题,并对产品进行了冲压工艺性分析,然后分析出产品开裂的主要原因是由于凸筋阻碍材料向边缘流动和翻边区域材料流动大,得不到及时补偿。最后提出设计工艺补充边和设计预成形工序等措施来改善汽车内板件冲压成形时出现的开裂现象。
The cracking problem in Stamping forming process for car inner panel was introduced,and anglicized the stamping formability of products.The results show that the product cracking is mainly due to material's flow block of the edge for the convex rib,and can not be compensated for large liquidity of flanging area in time.Finally,measures such as replenishing the design process and designing the pre-forming process are proposed to improve the cracking phenomenon occurring in the stamping of the inner panel of the automobile.
