传统的一个冲压件使用一副模具的生产方式,导致模具开发成本及周期增加,生产过程中生产不同的冲压件需要更换相应的模具致使生产效率低下。针对汽车发动机盖内、外板冲压件及开卷落料模结构相似的特点,研发了可实现多车型共用的开卷落料模,分析了该模具的工装设计要点,并将制造加工出的模具工装成功应用于某企业多个项目中。该结构有效地降低了模具开发成本及周期,连续生产无需更换模具,节省了换模时间,进一步提高生产效率。
The traditional stamping parts use a mold production method, leading to mold development costs and cycles increase, the production process of different stamping parts need to replace the corresponding mold resulting in low productivity. In view of the similar features of the automobile engine cover, the outer plate stamping parts and the uncoiler die structure, the uncoiling blanking die which can be shared by many vehicles has been developed. The key points of tooling design of the die are analyzed and the mold tooling Successfully applied to a number of projects in a business. The structure effectively reduces the mold development cost and the cycle. The continuous production does not need to change the mold, saves the mold changing time, and further improves the production efficiency.
