AI Technical Summary

Technical Problem

Existing automotive parts lack stress-directing and concentrated release structures during continuous molding processes, leading to workpiece springback, warping, twisting, or dimensional deviations, affecting molding stability and batch consistency.

Method used

A multi-module collaborative molding die is used to form a stress band in the middle of the strip. The forming punch and die work together to guide and concentrate the deformation stress of the strip, so that the load-bearing area and the stress band meet to form a stress concentration area. The stress band is then cut to release the stress.

Benefits of technology

It effectively reduces the retention of molding stress within the workpiece body, improves the molding stability and batch consistency of parts, reduces springback, warping and dimensional deviation, and extends service life.

Abstract

The application belongs to the technical field of automobile parts stamping forming, and particularly discloses a multi-module collaborative forming die for automobile parts, which comprises an upper die and a lower die, and a material belt passes between the upper die and the lower die along a flow direction; the upper die comprises a punching part and a forming female die, and the punching part is used for forming a stress belt at the middle of the material belt; the lower die comprises a forming male die, and the forming male die is matched with the forming female die to process the part of the material belt except the stress belt into a workpiece; the workpiece is provided with a force bearing area, and the part of the forming male die that forms the force bearing area corresponds to the material belt along the flow direction; the part is located at the top of the forming male die, so that the deformation direction of the material belt between the force bearing area and the stress belt intersects at the stress belt; the application has the following advantages: the stress belt is arranged to guide the deformation stress of the force bearing area to concentrate on the force bearing area, the residual stress of the workpiece is reduced, the actual service life of the workpiece is improved, and the springback, warping and size deviation are reduced.
