Abstract:

 The multistation layout was designed according to structural features and technical requirements of clamp part, and the mode with both intermediate carrier and bilateral carriers was designed to ensure the rigidity of strip in the feeding process. Then, the guide holes were set up on the bilateral carriers to ensure the feeding accuracy, and some idle stations were designed to ensure the installation of the punches and the strength of dies. Furthermore, the formal structure was used in the multistation progressive die of clamp, and the scraps and workpieces falled in different areas to save manpower. Finally, the pilots were set to determine the feeding distance,meanwhile the guide needles were set in the blanking stations to ensure the stamping accuracy of dies, and multi bending or reverse bending was designed to reduce the springback and ensure the workpiece dimension accuracy. The production results show that the product quality and productivity can be met by the multistation progressive die for clamp.
