Automobile door outer plate reinforcing plate part die

Abstract

The invention relates to an automobile door outer plate reinforcing plate part die which comprises an upper die component and a lower die component. The upper die component comprises an upper die holder, as well as an upper die core, an upper die insert block and an upper die eccentric swage, which are arranged on the upper die holder; the upper die core is positioned below the upper die holder; the lower die component comprises a lower die holder, as well as a lower die core and an ejector, which are arranged on the lower die holder; the lower die core is positioned above the lower die holder; the upper die component further comprises a plurality of upper push rods; the upper push rods penetrate through the upper die holder and are propped against the top of the upper die core; a shaving hole punching female die, flanging sizing female die, a trimming female die and a side hole punching female die are arranged on the upper die core; and a shaving hole punching male die, flanging sizing male die, a trimming male die and a side hole punching male die are arranged on lower die core. Compared with the prior art, the automobile door outer plate reinforcing plate part die has the advantages that three dies are integrated into one die, production processes are reduced, and the upper ejector structure is adopted to facilitate maintain.

Description

technical field [0001] The invention relates to a mould for automobile parts, in particular to a mould for reinforcing plate parts of automobile door outer panels, which completes the four processes of trimming, trimming and punching, punching side punching and flanging shaping at one time. Background technique [0002] At present, the automobile market is frequently updated, and the research and development cycle and market life of automobiles are getting shorter and shorter, which poses a serious challenge to the supporting parts molds. [0003] The existing automobile door outer panel reinforcement plate parts mold is divided into four processes, and four sub-process molds are required, which not only requires a large number of workers, but also causes defects such as high production cost, long manufacturing cycle and low production efficiency. [0004] On the other hand, the existing upper feeder uses a spring or a nitrogen gas spring as the power source, and the spring ...

AI Technical Summary

Problems solved by technology

[0003] The existing automobile door outer panel reinforcement plate part mold is divided into 4 processes, and 4 sets of process molds are used, which not only requires a large number of workers, but also causes defects such as high production cost, long manufacturing cycle, and low production efficiency.

[0004] On the other hand, the existing upper presser uses springs or nitrogen springs as the power source, and the springs or nitrogen springs will have normal damage and regular replacement requirements, which greatly increases the maintenance and replacement costs during the production process
