钢桶盖冲孔锁口二合一模具设计

Design of Two-in-One Die for Piercing Lock Opening of Steel Drum Cover

通常钢桶桶口件的锁口是先用冲孔翻边模对桶盖冲孔翻边,然后再用锁口模将桶口件法兰通过冲好的翻边孔铆合在桶盖上。锁口二合一模具结构不是二道工序模具的简单叠加,通过分析不同料厚桶盖对锁口的影响,阐述了二合一模具设计的结构特点。

Usually,the lock opening of the steel drum cover is firstly punching and flanging thedrum cover by using a piercing flanging die, and then rivet the barrel mouth piece on the steeldrum cover by using the lock opening die through the fianging hole.The two-in-one diestructure is not a simple superposition of the two step dies,through the analysis of the influenceof different material thickness steel drum cover on the lock opening,this paper expounds thestructural characteristics of the two-in-one die design.
