Vertical fork head cutting and punching die design
[Abstract] 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 molding tool in the industial production gain more attention, and be used in the industrial production more and more. Molding tool 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 cold punching technology. Parts design scheme of progressive die for parts design, layout, the size, the gap between die, the concave-convex mode shape dimension of other parts design, and make a choice, Discusses the forming principle of retaining clip parts, die structure and its design principles. This paper mould structure is simple, practical, and use examples of similar workpiece, convenient and reliable production has certain reference function.
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 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.
