Manufacturing method for easily-rebounded S-shaped-section sheet metal part and multi-station progressive die

Abstract

The invention discloses a manufacturing method for an easily-rebounded S-shaped-section sheet metal part. The manufacturing method includes a punching process, a trimming process, a trimming process, an upwards-forming process, an idling process, a flanging process, an idling process, a finish trimming and shaping process, an idling process and a cutting and punching process. By means of the manufacturing method for the easily-rebounded S-shaped-section sheet metal part, due to the reasonable arrangement of positions of the trimming process, the forming process, the flanging process and the idling process, the position precision of a punched hole, the position precision of a front notch and a rear notch, the forming quality of a manufactured part and the trimming quality of the outer edge are ensured in the corresponding die punching working process, in addition, the rebounding amount of the manufactured part after forming is greatly reduced, the die debugging cost is reduced, the production efficiency and the product qualification rate are improved, and the development period of a multi-station progressive die for the easily-rebounded S-shaped-section sheet metal part is shortened. The invention further provides the multi-station progressive die suitable for the easily-rebounded S-shaped-section sheet metal part.

Description

technical field [0001] The invention belongs to the technical field of metal stamping, in particular, the invention relates to a manufacturing method of an easily resilient S-shaped cross-section sheet metal part and a multi-station progressive die. Background technique [0002] Layout design is the key to the design of multi-station progressive die. The optimization of the layout diagram is not only related to the utilization rate of materials, the precision of parts, the difficulty and service life of mold manufacturing, but also directly related to the coordination and stability of the processing of each station of the mold. At present, the layout design of S-shaped sheet metal parts with easy springback is usually to use finite element simulation software to analyze and optimize the initial layout, and then determine the final layout until the simulation results meet the tolerance requirements of the product part drawing . If the initial layout is unreasonable, it will...

AI Technical Summary

Problems solved by technology

If the initial layout is unreasonable, it will increase the difficulty of later simulation analysis and optimization. Even if the difficulty is overcome and the qualified simulation results are obtained, the workload of mold debugging will be huge because the finite element simulation technology cannot truly replace the mold trial process.

This greatly restricts the improvement of the manufact
