[Abstract]Stamping products has been extensively applied in the industry, agriculture, national defense and in the daily lives of area, especially in the machinery industry. Mechanical products is the most pressing housing products, and the improvement of molds ,stamping,process and product design.
There are many ways of molding products of stamping. Piercing is mainly used for blanking, bending, stretching, etc. And Stamping molds almost form more than 60 percent of the total number. For example ,Electrical Control can be realized as semi-automatic or automatic operation. Cold-metal stamping die mainly used for the molding products, and it is very important in the production of stamping technology devices. The basic component of stamping molds is block model from top to bottom, mould plate, fixed-plate of mould plate, die inserts, raising nails, I. plate, plate unloading I. Introduction sets column, unloading bombs nail plate, plate Discharge and so on.
At present, used the high-speed cutting production mold already to become the major tendency which the mold made, produced the factory in the overseas some molds, the high speed engine bed area substitution electrical discharge machine, the high-speed cutting enhanced the mold production efficiency greatly. The engine bed enterprise aims at the mold production enterprise, above some processing center plant engine beds 60% sold to the mold processing enterprise. The high-speed cutting substituted for the electric spark precision work mold already generally to use gradually in the overseas mold manufacture enterprise, the high-speed cutting production mold already became the major tendency which the mold made greatly. Uses the high-speed cutting substitution electric spark production mold, may obviously enhance the efficiency, increase the mold precision, the service life is long.
