Abstract

The invention relates to an automobile top cover forming process method and the automobile top cover. The automobile roof forming process method includes the following steps: forming corner features at the corners around the sunroof hole of the blank, drawing and forming the blank to obtain a semi-finished roof; The side wall of the flanging on the side is provided with multi-level sinking steps, and the semi-finished top cover is flanged and shaped to obtain a top cover shaped product. The invention aims to solve the problem of wave and corner deformation on both sides of the sunroof after flanging and shaping on both sides of the sunroof on the roof of the car in the conventional technology.

Description

technical field [0001] The invention relates to the technical field of vehicle body forming, in particular to an automobile roof forming process method and the automobile roof. Background technique [0002] The car roof is a common outer cover in the automotive industry. The stamping process design of the car cover is based on the product's structural shape and technical requirements to determine the processes of drawing, trimming, punching, flanging, shaping and other processes. The process supplementary scheme of the process, and a reasonable process supplement and process scheme can reduce various quality defects. However, in the traditional technology, in order to set a larger-sized sunroof on the roof of the car, quality problems such as waves and corner deformations will appear on both sides of the sunroof after flanging and shaping on both sides of the sunroof on the roof of the car. Contents of the invention [0003] Based on this, the present invention provides a...
