Process additional method for vehicle exterior panel

Abstract

The invention discloses a technical supplement method of a vehicle external panel, wherein, the technical supplement towards the section of the external panel comprises the steps as follows: a horizontal line is made from the tangent point of the upper surface and a circular bead of the lateral wall; the extension line of the lateral wall is made from the endpoint of the lateral wall; the vertical line of the horizontal line is made from the endpoint of the horizontal line to get a first vertical line; the vertical line of the extension line of the lateral wall is made from the endpoint of the extension line of the lateral wall to get a second vertical line; the intersection point of the first vertical line and the second vertical line is considered as the center of a circle, and the length of the second vertical line is considered as the semidiameter to make a circle to get a cavity die circular bead; the horizontal line is made from the intersection point of the cavity die circular bead and the first vertical line to get a swaging line. The technical supplement method provided by the invention not only can ensure that the surface of the finally molded external panel does not have a slip line, thereby improving the surface quality of the vehicle external panel, but the technical supplement method also reduces the designing and manufacturing period of a die and improves the production efficiency.

Description

technical field [0001] The invention relates to the field of die stamping, and more specifically, relates to a method for supplementing a vehicle outer panel. Background technique [0002] In recent years, the stamping process has been widely used in the automobile manufacturing industry. Many outer panel covers and inner panels in vehicles are stamped by dies. Usually, the first step in forming a part with a mold is to use a drawing die to draw and shape the blank sheet, and then perform punching, trimming, flanging, shaping, etc. according to the specific requirements of the shape of the part. Before designing and manufacturing the drawing die for drawing and shaping the sheet, the first thing to do is to supplement the shape of the part according to the shape of the part to be formed, so as to design the mold shape of the drawing die. noodle. [0003] However, in actual production, some outer panels in the vehicle will be scratched when the blank passes through the end ...
