THE DESIGN OF BENDING DIE FOR THE FEET

ABSTRACT

Punching die has been widely used in industrial production.In the traditional industrial production,the worker work very hard,and there are too much work,so the efficiency is low.With the development of the science and technology nowadays,the use of punching die in the industial production gain more attention, and be used in the industrial production more and more.Self-acting feed technology of punching die is also used in production, punching die could increase the efficience of production and could alleviate the work burden，so it has significant meaning in technologic progress and economic value.
The article mainly discussed the classification,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 die for the feet have saved the trouble of the punching .for The punching dies that utilized the feature of the normal punch shaped the workpiece in the room temperature,and its efficiency and economic situation is excellent.
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.
