Abstract:

 According to the structural features of claw, its stamping process property was analyzed, and the stamping design scheme of multi-station progressive mold was presented. Then, the layout scheme with twenty-three stations was worked out, and the bending station was decomposed into a combination of multiple bending and bending correction to reduce the bending springback of part. Furthermore, the unilateral carrier was used in the layout design scheme, and the idle stations were designed to ensure the strength of punch and die insert and realize the reasonable distribution of deformation amount of part during the forming process. In addition, the overall structure of multi-station progressive mold was introduced, the forming part adopted an easy-to-replace insert structure, the guide pin and discharge pin were used for straighten and unloading, the elastic bearing pin was used for bearing, and the step distance was set to 10 mm. The production practice shows that the layout scheme is reasonable, the structure of mold is flexible and reliable, and the quality of product is favorable to meet the requirement of use.
