Tray stamping mould design
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.
This Article proposes using mold to produce retainer of the new technology, And against a standard fixture retainer design of the compound dies. The main problems of this mold design is how to solve retainer of punching holes, determine mold structure, how to manufacturing the mold and selected blanking programs and so on. This Article Combine the characteristics of retainer, concretely solve the choice and verify check of the press machine, the numeration and structure design of the point dimension of punch and matrix, the locating project design, the method of stripper, the main mold parts processing, the choice of standard parts, the design of the model assemble. These designs can provide realistic guiding significance for similar mold design. But the characteristics of the design is to try to using the complicate dies. To solve the problem of original process, such as large numbers of die, long process of technology, high production cost, low efficiency, difficulty in keeping symmetry of working parts are solved, and a reliable evidence for the workout of stamping process and die design of these parts is provided.
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: dies; compound dies; blanking force; blanking dearance
