Continuous production die for rear portion blanking plate parts of automobile carling

Abstract

The invention relates to a continuous production die for rear portion blanking plate parts of an automobile carling. The continuous production die for the rear portion blanking plate parts of the automobile carling comprises a lower die portion and an upper die portion, the lower die portion comprises a lower die seat (1), a stamping female die cutter (2), a lower die trimming cutter block (3), a lower flanging male die (8), a shaping block, and a discharge opening,wherein the stamping female die cutter(2),the lower die trimming cutter block(3),the lower flanging male die(8),the shaping block and the discharge opening are arranged on the lower die seat(1) in sequence.The upper die portion comprises an upper die seat (4), a stamping male die cutter, an upper die trimming cutter block, a flanging cutter (9), a pressure plate (5) and a shaping punch (6), wherein the stamping male die cutter,the upper die trimming cutter block,the flanging cutter (9) ,the pressure plate (5) and the shaping punch (6) are arranged at the lower surface of the upper die seat (4) in sequence; the pressure plate (5) is arranged at the lower middle portion of the upper die trimming cutter block and is connected with the upper die trimming cutter block. Compared with the prior art, the continuous production die for the rear portion blanking plate parts of the automobile carling has the advantages of being high in quality, convenient to maintain low in cost and the like.

Description

technical field [0001] The invention relates to a rear sealing plate part of an automobile longitudinal beam, in particular to a mold for continuous production of the rear sealing plate part of an automobile longitudinal beam. Background technique [0002] The vast majority of modern cars have a frame as the skeleton of the whole car. The frame is the base of the whole car. Its function is to support and connect the parts of the car, and to bear various loads from inside and outside the car. The frame is usually composed of longitudinal beams and beams, which are connected by riveting or welding to form a strong rigid frame. Among them, the longitudinal beam of the automobile has a great influence on the collision performance of the automobile body, so the longitudinal beam is required to have good impact resistance and bending resistance. [0003] Automobile longitudinal beams are usually stamped from low-alloy steel plates, and their cross-sectional shape is generally U-s...

AI Technical Summary

Problems solved by technology

The existing sealing plate at the rear of the longitudinal beam is produced through five processes: material cutting, drawing, trimming and punching, flanging and shaping, and separation. In many cases, traditional molds can only punch one half-process part at a time during the production process. , and the use of drawing technology in production increases the cost of stamping, there are safety hazards in the process of personnel operation, and the quality of stamped parts is caused by human misoperation
