Abstract

The invention provides a cascading continuous stamping die used for manufacturing fixed panels of automobile door hinges, which can greatly improve processing efficiency of the fixed panels of the automobile door hinges and qualification rate of finished products, and simultaneously reduce production cost. The cascading continuous stamping die comprises a top die structure and a lower die structure, wherein the top die structure and the lower die structure are arranged in right position and aligned with each other by an aligning structure, and the lower die structure is provided with a waste cutter; and a die hole corresponding to the top die structure and the lower die structure is provided with a hole punching structure, a stretching structure, and an upsetting structure.

Description

(1) Technical field [0001] The invention relates to the technical field of moulds, in particular to a progressive continuous stamping die for manufacturing automobile door hinge fixing plates. (2) Background technology [0002] When processing the fixed plate of automobile door hinge with ordinary mold, the material will become thinner during the stretching process of the stamping part, so that the wall thickness of the screw hole of the processed car door screw tooth plate cannot meet the technical requirements, the thread strength is low, and its processing efficiency is low. The qualified rate of finished products is low, and the production cost is high. (3) Contents of the invention [0003] In view of the above problems, the present invention provides a progressive continuous stamping die for manufacturing automobile door hinge fixed plates, which can greatly improve the processing efficiency of automobile door hinge fixed plates, improve the qualified rate of finishe...
