子母合页P形弯曲级进模设计

Design of progressive die for P-shaped bending of hinges

分析了子母合页的成形工艺,将压端头与卷圆2道单工序模设计成1道简单的P形弯曲级进模,在降低模具制造成本的同时提高了零件的生产效率,并通过对压端头上模和导向板结构的合理设计,使子母合页能在同一副模具上成形。该模具很好地兼顾了模具成本、生产效率、零件质量和模具通用性4个方面的平衡,对类似零件的冲模设计具有一定的借鉴作用。

The forming process of hinges was analyzed. Changing stamping and rolling pro- cesses into a simple P-shaped bending progressive die, which reduced die manufacturing costs and improved production efficiency. It could form the hinges on a die through reason- ably designing the stamping punch and guide plate structure. The die took account of the cost of the die, production efficiency, product quality and versatility, which provided refer- ences for stamping die design of similar parts.
