This article focuses on the analysis of the process of the workpiece; layout diagram of the design and determination; calculation of the process parameters; mold structure to select and check; the choice of the press; mold of economic analysis; as well as the typical mold machining process analysis. The workpiece is designed by using a multi-position progressive die. The mold is divided into nine stations. The first station is to punch a pin hole, the second station is to pre-punching before flanging, the third station is to trim, the fourth, fifth, sixth, seventh, eighth station are to bend, meanwhile the eighth station is to flange the hole, the ninth station is to blank. The floating roof is needed to set in the die because of the process of bending, in order to feed the workpiece forward. Meanwhile it is needed to set the escape space in the die board or in the discharge board in the corresponding position. In order to ensure the punching accuracy and the stability of the mold, it is required to set up small guide posts and guide sleeve in the discharge board. It improves the productivity greatly, reduces the labor and has the characteristics of precise step, easy maintain and high precise parts by u
