Abstract：

Audio interface parts have the features of small size,high request of precision and complex coiling configura- tions.In the article,the technology of punching with progressive die was analyzed and the scheme was also confirmed. By comparing the two common coiling configurations,the improving working procedure step by step shaping with coi- ling was determined.Compared with traditional scheme,the defects,such as big error of multi-orientating and the lower security in operation were avoided.The reliability of production was enhanced and exploitation cost was reduced. Furthermore,the rational sequence of scheme was arranged based on the characteristics of the part.For avoiding punc- hing two times,arc transitional joint edge was designed.According to the rational layout project,an improved struc- ture of the die was designed in which precise guided structure,brace framework,adjustable-pressure stuff-unload set- ting and floating orienting pin-thimble framework were applied to guarantee the stability and security of the operation of the die.Therefore,the article has a certain reference value for designing the progressive die of similar parts.
