Abstract

The present application provides a forming process for an automobile tail lamp seat plate, which includes: S1, symmetrically splicing the left and right processed parts to form a tail light seat plate blank structure; S2, double drawing the tail light seat plate blank structure Forming processing, and form a left over-drawing convex hull in the middle of the left workpiece, and form a left shaping reserved convex hull at the tail, form a right over-drawing convex hull in the middle of the right workpiece, and form a right shaping reserved convex hull at the tail ; S3, perform post-process trimming and shaping processing on the blank structure of the tail light seat plate in sequence; S4, perform flanging and shaping processing on the blank structure of the tail light seat plate in sequence; S5, perform punching and side punching on the blank structure of the tail light seat plate Processing; S6, trimming and separating the blank structure of the tail lamp seat plate and processing side punching holes. This process can complete the processing and molding of the tail light seat plate with complex structure, and effectively prevent the tail light seat plate from cracking during processing.

Description

technical field [0001] The present application relates to the field of automobile technology, in particular to a molding process of an automobile tail lamp seat plate. Background technique [0002] The taillight seat plate is the main installation carrier for the taillights of the car body. It is overlapped with parts such as side panels, gutters, and rear panels. The tolerance requirements for the overlapping surfaces and mounting holes are very high. The structure of the seat plate parts is complex and difficult to process. [0003] Such as figure 1 and figure 2 As shown, especially the overlapping portion 3 of the taillight seat plate 1, the side wall 2 and the rear bumper, the side wall is attached to the sharp corner of the side wall. R also cannot be increased, which leads to difficulty in forming the taillight seat plate 1, limits the adjustment space during design, and is not conducive to the improvement of taillight design and vehicle shape. Contents of the in...
