Analysis of Stent Forming Process and Multi - Position Progressive Die

Abstract: Multi-station progressive die is an important part of the stamping die, the punching, bending, stretching, forming process integration in one, on behalf of modern advanced production mode of precision molds。 The graduation design is the stent forming process analysis and multi-station progressive die design, the workpiece to manipulate the bracket as the object, detailing from the product process analysis, calculation data and check to the final mold design of the whole process。 This is a separate project to contact the reality of the actual production, through access to a large number of literature and self-learning and mold design-related knowledge, and then multi-station progressive die design。 The design of the main use of the UG software in the progressive die module, the system from the nest design to mold, punching, bending, forming convex and die and blanking die design and guide column, guide sleeve, screws, pins To add。 After the completion of the mold design, simulation operation and to improve the mold, once again on the mold and related data to check to determine the mold design is reasonable。 Finally, through Autocad to complete the assembly sketch, assembly drawings, parts engineering drawings, and to write a summary of the design instructions。

Key words: Manipulate the bracket；Layout design；Progressive die；Stamping die design
