Abstract

The invention discloses a bending forming device of an automobile door frame rear door C column, and belongs to automobile C column machining equipment. The bending forming device comprises an upper profile block and a lower profile block. After the upper profile block and the lower profile block are combined, the front section of the endpoint of the C column is pressed into a set shape, the upperprofile block is rotationally mounted above the lower profile block through a hinge structure, and the hinge structure drives the upper profile block to rotate downwards along the bending trend of the front section of the endpoint as the upper profile block moves to make contact with the to-be-bent C column or the lower profile block downwards. The bending forming device further comprises a transverse feeding mechanism, and the transverse feeding mechanism drives a side push mechanism to extrude a door frame to enable the front section of the endpoint to be transversely bent into the set radian. By means of the bending forming device, inner arc wrinkles and sunken portions generated at the bent position of the front section of the endpoint of the C column can be avoided as much as possible, and the structural performance and attractiveness of the C column are effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of stamping and forming of a C-pillar of a rear door of an automobile door frame, and in particular relates to a press-bending device for a C-pillar of a rear door of an automobile door frame. Background technique [0002] The shape of the C-pillar of the rear door of the automobile door frame is a three-dimensional shape, which needs to undergo such figure 1 - Two kinds of bending process shown in 2, wherein, figure 1 In order to bend the front end section a of the C-pillar downward to a predetermined arc, figure 2 For the transverse bending of the front section a of the end to a certain radian. In the prior art, when the stamping die is directly bent in the vertical or horizontal direction, the inner arc is prone to wrinkling and depression at the bending position, which seriously affects the structural performance and aesthetics of the C-pillar . Contents of the invention [0003] The purpose of th...
