Abstract：

The technological characteristics of center door guide pulley fixing plate were analyzed, and the precise progressive die was determined to produce.The design of the part layout, die structure and key components was introduced. The automatic feeding mechanism as rough location, accurate positioning by pilot pin and three types of floating material device were adopted for the die which guaranteed the feeding precision. The insert structure was applied in all the functional parts which is easily for manufacturing，assembling, modification and repairing.After mass production, the practice shows that the structure of die is reasonable and convenient operation,meanwhile it meets the production desire of mass production,high efficiency and good quality.
