汽车门锁加强板成形工艺优化设计

Optimization design of forming process for automobile door lock reinforce plate

通过对汽车门锁加强板制件的拉深工艺分析,针对制件拉深过程中存在异形孔和异形边变形问题,通过氮气弹簧的使用、拉深毛坯定位形式的改进以及局部拉深筋的设置,保证制件拉深成形质量,借助有限元数值模拟手段,优化了制件成形工艺,缩短模具设计周期。

Based on the analysis of drawing process for the reinforce plate of automobile door lock, the deformation of special holes and edges was existing in drawing process. It ensured the quality of the products by the usage of nitrogen spring, the improvement of drawing blank positioning method and the setting of local drawbead. Also the design process was optimized by using the finite element numerical simulation method.
