Abstract：

The stamping process and function of socket housing with external dimensions of 83.2 mm × 14 mm × 10.7 mm, material thickness of 0.3 mm were analyzed, and two kinds of layout design for socket housing progressive die were conducted. By comparison，a reasonable layout design was selected, and the multi-position progressive die with external dimensions of 690 mm × 385 mm, shut height of 220 mm was designed. Then the design of overall structure of the die, pilot pin and side edge, punch were introduced. The die with an intermediate vector nesting process can improve material utilization and simplify the structure. Especially，by the technology of pressing triangle line in six bayonets of parts, the difficulty in coming of 90 ° bend die insert that resulted in large sunk defects after preventing collision with the plastic parts was solved. Practice shows that the die has compact structure and reasonable design, therefore good quality parts are produced and the requirement of mass production is met.
