The structure and shape of bracket parts are extremely complex and demands，and the production is difficult for the tendons and flanging distributing in different surfaces, poor feeding caused by long strip and lacking of rigidity, positioning imprecision etc. By the measures of improving mold precision and position accuracy, and adopting correctly nesting such  as stamping process and sizing etc., the accuracy requirements of parts were achieved. The complex shape of  part was achieved through the progressive forming; beading and flanging on different surfaces was achieved through properly design of process piece shape before beading and flanging. The problems of long strip and lacking of rigidity were solved through making the strip into L-shaped and redesigned floating material parts. Meanwhile, a fully three-dimensional mold design was adopted,which is easy to generate subsequent CNC machining process. And then, for the common discharge of troublesome operation when tightening and loosening the screw，redesign was conducted to make it easy to be operated.
