摘要
通过对轴承保持架拉伸工艺及成形过程的分析,找出了零件破裂的原因,改进了原加工工艺方案,通过设置预冲孔、分步成形,改善了成形条件,据此重新设计及改进模具,生产出了合格的产品。
Through analyzing drawing forming process of bearing maintainer,found out the cause of part cracking, improved original forming process project, through eatablishing pre-punching hole and forming step by step, improved forming condition, redesigned the die, and production quality was good.
