Abstract

The invention relates to an automobile part continuous production die provided with a pre-flanging mechanism. The automobile part continuous production die provided with the pre-flanging mechanism comprises an upper die part, a lower die part and guide posts. The upper die part comprises an upper die seat, a press plate, a puncher pin, an upper die trimming knife, an upper die pre-flanging mechanism body, an upper die complete flanging mechanism body and a material ejection groove, wherein the press plate, the puncher pin, the upper die trimming knife, the upper die pre-flanging mechanism body and the upper die complete flanging mechanism body are fixed to the lower surface of the upper die seat; and the material ejection groove is formed in the lower surface of the upper die seat. The lower die part comprises a lower die seat, a punching female die body, a lower die trimming knife, a lower die pre-flanging mechanism body, a lower die complete flanging mechanism body and a material ejection rod, wherein the punching female die body, the lower die trimming knife, the lower die pre-flanging mechanism body, the lower die complete flanging mechanism body and the material ejection rod are fixed to the upper surface of the lower die seat. In the working process, the puncher pin and the punching female die body are matched for conducting punching action; the lower die trimming knife and the upper die trimming knife are matched for conducting trimming action; the upper die pre-flanging mechanism body and the lower die pre-flanging mechanism body are matched for conducting pre-flanging action; and the upper die complete flanging mechanism body and the lower die complete flanging mechanism body are matched for conducting complete flanging action. Compared with the prior art, the automobile part continuous production die provided with the pre-flanging mechanism has the advantages of being long in service life, convenient to maintain, high in punching efficiency and the like.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for continuous production of automobile parts with a pre-flange mechanism. Background technique [0002] The guide rail is an important part of the car body. The strength and quality of the guide rail directly affect the overall safety of the car. The production stability of the guide rail is very important. At present, in many cases, traditional molds can only punch one half-process part at a time during the production process, and drawing technology is used in production. Increase stamping cost. There are potential safety hazards in the process of personnel operation, and the quality problems of stamping parts caused by human misoperation. At the same time, when the flanging angle of auto parts is large, if the flanging is done directly, the parts will be rough and the flanging will rebound Contents of the invention [0003] The purpose of the present invention is to provide a continuous p...
