Automobile side frame inner panel part die

Abstract

The invention relates to an automobile side frame inner panel 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 and a flanging sizing female die are arranged on the upper die core; and a shaving hole punching male die and a flanging sizing male die matched with the shaving hole punching female die and the flanging sizing female die are arranged on the lower die core. Compared with the prior art, the automobile side frame inner panel part die has the advantages that three dies are integrated into one die, production processes are reduced, the upper ejector structure is adopted, the die is convenient to maintain, and a swaging power source is not required to be inspected or changed before production every time.

Description

technical field [0001] The invention relates to an automobile part mold, in particular to an automobile side wall inner panel part mold. Background technique [0002] The current automobile market is frequently updated, and the research and development cycle and market life of automobiles are getting shorter and shorter, which poses a severe challenge to the matching parts and molds. The inner panel of the side wall of the car mainly includes C-pillar, D-pillar, rear side window frame and lightening hole, etc., which is an important part of the car. [0003] Existing automotive side wall inner panel parts molds are divided into two processes, and two strokes are required during production, which not only requires a large number of operators, but also increases the manufacturing cost, and the manufacturing cycle becomes longer and the production efficiency is not high. [0004] On the other hand, the existing upper presser uses springs or nitrogen springs as the power source...

AI Technical Summary

Problems solved by technology

[0003] Existing automotive side wall inner panel parts molds are divided into two processes, and two punches are required during production, which not only requires a large number of operators, but also increases the manufacturing cost, and the manufacturing cycle becomes longer and the production efficiency is not high

[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 be damaged normally and require regular replacement, resulting in a significant increase in maintenance and replacement costs during the production process
