Abstract：

The stamping process of fork-shaped electrical conductive part was analyzed based on its structure characteristics. The two sets of layout schemes were designed. The single row layout with the parts upside down was confirmed by comparing the above two layout schemes,which consists of 12 processes including punching, profiling, bending, empty station, cutting and etc. When the strip is moved forward every step, two parts are obtained, so the parts are forced uniformly. In consequence, material utilization and producing efficiency are much higher. The alien shaped blanking punches were all positioned by local stairs and some of which were designed as a structure of the upper part in integral while the lower in sub-structure. Dies were designed as die inserts, and die inserts of partial blanking processes were designed as an integral structure. In order to ensure the accuracy of the bending parts, two upward bending processes were applied in the angle bending with the elastic ejection devices playing the roles of pressure and unloading for the part.
