Abstract: It described the stamping and bending process of the contact piece of the side steering lamp holder, analyzed the layout of the parts, introduced the design features of the die structure, and explained the design of the punch and concave die, the design of the folding and pressing insert at the area of the needle shaped on the head of part, and the design of the lateral forming insert. The production practice proved that the die structure was compact and reasonable, and the shape and size of the produced parts met the requirements, which could provide some reference for the die design of similar parts.
