The present paper basis product pattern, the analysis blanking shape, the characteristic, the size size precision request,the surface quality and use ramming labor world and so on the material, in this foundation, according to the superposable die the superposable die which was highly effective, high grade and so on the characteristic selects inverts, on, got down the waste material, the waste material discharges directly from the punch press Taiwan face,did not block, ease of operation, security. The top die uses the rubber, plays to the certain smooth role, improves the work piece quality, even reduces the working procedure. Has designed the convex-concave mold, the raised mold, the concave mold structure separately, the raised mold uses takes shape the processing or the line cuts, the blanking partially carries on the heat treatment, by the screw retention, the rigidity pushes, the elastic dumping device rubber elasticity from bootom to top promotes the yard lumber, but acts along with the top die movement, the movement steady reliable also is not easy to damage the mold among, uses the guide pillar circular to have the use installment, also because of does not install when but creates the mold damage, according to flushes the pressure to choose the type fixed platform press.
Key word: Blanking superposable die design.
