英文摘要
【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 product performance requires of high-quality performance stamping 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.
The article mainly discussed the Circlearound,feature and the developmental direction of the pnnching technology. Elaborated the punching
components formation principle, the basic dies structure and the rate process and the principle of design; and designed some conventional
punching die.
The dies here discussed can be easily made,conveniently used, and safely operated.And it could be used as the reference in the large scale
production of similar workpieces.
【Key words】punching die ,machincal,manufacture，die design
