发动机罩共用开卷落料模设计与应用

Design and application of shared decoiling punching die for engine hood

研发了1副依靠固定式弧形切断刀和移动式切断单元实现“一出二”的开卷落料模,实现不同步距发动机罩内板和外板共用生产,阐述了落料模结构特点和优势,并将制造的模具成功应用在实际生产中,提高了生产效率,降低了生产成本和模具开发成本。

A pair of decoiling punching die was developed to realize"one out of two"production by relying on the fixed arc cut-off tool and the mobile cutting unit,which could realise non-synchro⁃nous distance engine hood inner plate and outer plate sharing production.The structural character⁃istics and advantages of the punching die were described,and the manufactured die was success⁃fully applied in actual production,which improved the production efficiency and reduced the pro⁃duction cost and the development cost of the die.
