Problems solved by technology

[0002] At present, the mold of automotive lock reinforcement plate parts is generally divided into four processes: drawing, trimming and punching, flanging and shaping, and trimming and punching. Four punches are required for production, which requires a large number of operators and high manufacturing costs. , long manufacturing cycle, low production efficiency
The existing upper mold presser uses spring or nitrogen spring as the power source, and the spring or nitrogen spring will be damaged normally and require regular replacement, and the maintenance and replacement costs during the production process will be greatly increased

Abstract

The invention relates to an automobile lock reinforcing plate part die. The die comprises a lower die and an upper die. The lower die is provided with a trimming piercing male die (2), a first flanging sizing male die (4), a second flanging sizing male die (6) and a side piercing male die (8). The upper die is provided with a trimming piercing female die (3), a first flanging sizing female die (5), a second flanging sizing female die (7) and a side piercing female die (9), which are corresponding to the lower die. Four actions of drawing, trimming piercing, flanging sizing and trimming piercing are combined, so a continuous combination die is formed. Compared with the prior art, the die disclosed by the invention has the advantages of low production cost, safety, reliability and the like.

Description

technical field [0001] The invention relates to a mold for producing automobile parts, in particular to a mold for automobile lock reinforcement plate parts. Background technique [0002] At present, the mold of automotive lock reinforcement plate parts is generally divided into four processes: drawing, trimming and punching, flanging and shaping, and trimming and punching. Four punches are required for production, which requires a large number of operators and high manufacturing costs. , the manufacturing cycle is long, and the production efficiency is not high. The existing upper mold presser uses a spring or nitrogen spring as a power source, and the spring or nitrogen spring will be damaged normally and requires regular replacement, and the maintenance and replacement costs during the production process will be greatly increased. Contents of the invention [0003] The purpose of the present invention is to provide a low production cost and easy maintenance automotive ...
