Problems solved by technology

When flanging, since the tail light area of ​​the side wall outer panel is formed as a one-time overall flanging, and the material is obtained from the outer side of the side wall outer panel, a large number of waves and waves are generated at the corners of the tail light area of ​​the side wall outer panel. Dark pits, waves and dark pits not only affect the surface quality of the side panel, if the situation is serious, it will cause production shutdown and scrap parts

Abstract

The invention relates to the technical field of automobile covering part forming, and discloses a flanging process and a pre-flanging device. The flanging process comprises the steps that a taillightarea of a side wall outer plate is divided into two parts; the side wall outer plate is put into a pre-flanging device; the pre-flanging device is used for conducting stamping pre-flanging on the taillight area of the side wall outer plate divided into two parts, so that a pre-flanging structure bent towards the inner side face is formed in the taillight area of the side wall outer plate; the sidewall outer plate is taken out from the pre-flanging device and placed into a flanging device; and the flanging device is used for conducting stamping flanging on the side wall outer plate, and the side wall outer plate with a flanging structure is obtained. By means of the method, the material requirement trend of the side wall outer plate from the outer side face can be relieved through the flanging process, and waves and dark pits on the outer side face of the taillight area of the side wall outer plate can be eliminated.

Description

technical field [0001] The invention relates to the technical field of automobile cover molding, in particular to a flanging process and a pre-flange device. Background technique [0002] With the development of society, cars have become an indispensable part of people's lives, and people have higher and higher requirements for the appearance of cars. [0003] Due to the technical requirements and aesthetic requirements, the side panel parts of the automobile need to be flanged. When flanging, because the tail light area of ​​the side wall outer panel is formed as a one-time integral flanging, and the material is obtained from the outer side of the side wall outer panel, a large number of waves and waves are generated at the corners of the tail light area of ​​the side wall outer panel. Dark pits, waves and dark pits not only affect the surface quality of the side panel, if the situation is serious, it will cause production shutdown and scrap parts. Contents of the invent...
