Research on Progressive Die Design for Asymmetric U-Shaped Contactor

Article Preview

Abstract:

The pressing technologies and the forming difficulties of the asymmetric U-shaped contactor were analyzed. The strip layout was designed for progressive pressing from piercing to bending. The die structure was designed in three plates mode, guiding with ball cage bush and pillar mechanism. The multiple steps bending stations and sliding inclined wedge mechanism were designed to implement the critical forming function. The volume production proved that this toolset’s structure was robust at high stamping speed and the products meet the high quality criteria. A valuable universal design rule was concluded for similar product’s toolset design.
