Development and Application of the Optimization Design of Progressive Die Based on Transfer Unit
The objective of this study was to research a newly progressive die , which unifies the merit of high efficiency of the progressive dies and the high material-using ratio of the project dies. This paper analyzes the forming process methods of IHS(Intel Heat Spreader), and develop a set of progressive die with transfer unit , which turns project die to progressive die. The cooperation between the transfer unit and the die was studied, and the key technology of the newly progressive dies were investigated. Compared with the traditional die, the mechanization and electrization are realized to increase the production efficiency and get highly precise IHS. The newly designed transfer unit is expected to be a helpful reference for designers facing demands for higher quality, lower cost and shorter delivery time for some special products.
