A method for molding the mold surface of an outer panel

Abstract

The present invention provides a mold surface molding method for an outer panel, which is used in the drawing process or the flanging process, and is suitable for the A surface of the outer panel, where the A surface of the outer panel is a boundary fillet or The surface of the part except the boundary fillet includes shape adjustment and pressing material control. The shape adjustment specifically includes the following steps: step S1, determine the position and value of the surface depression prone to occur on the surface A of the outer panel; step S2, for The sag-prone area is reversely compensated; after reverse compensation, the A side of the obtained outer panel all meets the set product surface and meets the requirements of the A side. When the mold surface modeling method is used, it can ensure that the finally obtained outer panel has few surface defects, reduce the on-site debugging man-hours of technicians, reduce labor intensity, and lower the technical requirements for technicians at the same time.

Description

technical field [0001] The invention relates to the stamping field of automobile outer panel parts, in particular to a method for molding the mold surface of an outer panel part. Background technique [0002] The competition in the automobile market is becoming increasingly fierce, and users have higher and higher requirements for the appearance quality and individualization of the automobile body. Nowadays, more and more models are pursuing clear and beautiful appearance lines. The outer panels include the outer side of the automobile, fenders, front and rear doors. The parts that can be seen directly on the car, such as the outer panel and the front and rear cover outer panels, have complex curved surfaces and high requirements for size and surface quality. Pimples and small convex bumps on the surface of parts are the most common surface defects.

[0002] The competition in the automobile market is becoming increasingly fierce, and users have higher and higher requirements for the appearance quality and individualization of the automobile body. Nowadays, more and more models are pursuing clear and beautiful appearance lines. The outer panels include the outer side of the automobile, fenders, front and rear doors. The parts that can be seen directly on the car, such as the outer panel and the front and rear cover outer panels, have complex curved surfaces and high requirements for size and surface quality. Pimples and small convex bumps on the surface of parts are the most common surface defects. Stamping of outer panels Afterwards, the parts are beaten with oilstone, and there is no oilstone in the concave area and the oilstone in the convex area is shiny. These defects directly affect the appearance of the parts after painting. Surface defects not only have a great impact on the appearance quality of the car body, but even damage the surface of the vehicle. Rigidity, while traditional on-site debugging is used to solve surface problems, the on-site debugging work cycle is long, the technical requirements for technicians are also high, and the improvement effect is not stable
