The rotor shape is more complex，with 16 of uniform distribution of circular parts，and the shape is more complex，and is not very regular，so its processing is difficult. Compound structure forms using inversion typical structure, below is intensive, at this point the waste hole rotor films leave out from the table, and the workpiece in the die, Introduction of rigid push pieces of workpiece, unloading using elastic stripper plate. A brief overview of the design specification of the current development of stamping dies and trends. Then carried out a detailed piece of analysis, and stamping process to determine the program. Stamping die design in accordance with the general steps to calculate and design a set of mold on the main components，Such as: the punch and die, intensive, punch fixed plate, plate, plate, dies.the fixed stripper plate, block material pin, top material, the top pieces etc，punch and die shapes are more complex, so with spelling type structure. Each of the parts of mould correct choice materials, to ensure the accuracy of mould design. Formwork using standard formwork, choose a suitable press equipment，Design and choose a job with the automatic mould,Write the main parts of the machining process and the process card. Using the Pro / e design three-dimensional view of the composite mold, and use AUTOCAD drawing Assembly and major work of parts. Use the mold production of workpieces surface of good quality, high precision, simple operation, and high production efficien
