A mold for automobile front seat support plate assembly parts

Abstract

The invention relates to a die for a part of an automobile front seat supporting plate assembly. The die comprises a lower die base and an upper die base; a front trimming and piercing unit, a drawing unit, a rear trimming and piercing unit, a flanging and restriking unit and a piercing and separating unit are sequentially arranged between the lower die base and the upper die base in the moving direction of a material belt; and the piercing and separating unit comprises a first piercing and separating mechanism and a second piercing and separating mechanism which are sequentially arranged in the moving direction of the material belt. According to the die, compared with the prior art, the four processes of drawing, trimming and piercing, flanging and restriking as well as piercing and separating are combined together, and the four processes can be simultaneously conducted during stamping every time, so that three dies are saved, three times of stamping are decreased, machine tools and staff are saved, the production cost and the maintenance cost are reduced, and the production efficiency is improved; and moreover, an upper material pressing device is of an upper ejector rod structure, the material pressing effect is good, and maintenance is convenient.

Description

technical field [0001] The invention belongs to the technical field of automobile parts production, and relates to a mold for an assembly part of an automobile front seat support plate. Background technique [0002] The front seat support plate assembly is an indispensable part of the automobile body, and its quality stability plays a particularly important role in the safety of the automobile. Previously, this type of mold was divided into 4 processes, which were drawing, trimming and punching, flanging and shaping, and punching separation. During production, four punches were required, requiring a large number of operators, the production efficiency was not high, and the quality of the parts was not enough. Stablize. [0003] Authorized announcement number is the Chinese invention patent of CN103182445B has announced a kind of mold of automobile tailgate part, comprises lower mold and upper mold, and described lower mold comprises lower mold base, lower mold core and ejec...

AI Technical Summary

Problems solved by technology

The technical solution disclosed in the above-mentioned patent combines the three actions of edge trimming, punching, flanging and shaping, and side punching, which improves the production efficiency of automobile rear panel parts to a certain extent, but the mold does not have the functions of drawing, punching, etc. Functions such as separation cannot be used in the production and processing of automotive front seat support plate assembly parts, etc.
