Abstract: The blanking and bending process of the fixed fastener was described, and the layout of the part was analyzed. It introduced the characteristics of die design and illustrated the design of the main template. The design of the inserts for vertical 90° bending at the convex hull, and for succession wave and 90° bending were explained. The production practice proved that the die structure was compact and reasonable, the shape and size of the parts met the drawing requirements, which could provide a reference for the die design of similar parts.
Key words: fixed fastener; bending forming; micro-interference design; progressive die; springback offset
