Method for improving quality of surface near ridge line of automobile covering part outer plate

Abstract

The invention relates to a method for improving the quality of a surface near a ridge line of an automobile covering part outer plate. The method comprises the following steps that S1, the ridge line on which a slip line can appear in a normal debugging process of the covering part outer plate is determined, and the ridge line is marked as a ridge line 1 to be treated; and S2, in the fine modeling process of the covering part outer plate, strong pressure treatment is carried out near the ridge line 1 to be treated, the areas subjected to strong pressure treatment are within the Ymm ranges of the two sides of the ridge line 1 to be treated, the strong pressure value ranges from 0.1 mm to 0.12 mm, and Y is larger than or equal to 8 and smaller than or equal to 12. According to the method for improving the surface quality, the problem of difficulty in solving the problem that the slip line appears near the ridge line in the testing process is solved, operation is convenient, the situation that the slip lines appear near the ridge lines of the covering part outer plate in the testing process can be effectively reduced, the surface quality near the ridge lines of the outer plate is improved, the mold debugging difficulty is effectively reduced, and the grinding time of the mold is shortened.

Description

technical field [0001] The invention relates to the field of manufacturing automobile outer covering parts, in particular to a method for improving the surface quality near the ridge line of the outer plate of the automobile covering part. Background technique [0002] In the later on-site debugging of the mold of the outer panel of the automobile panel (including the fender, the outer panel of the front cover, the upper outer panel of the lift door, the upper outer panel of the rear cover, etc.), various surfaces of the outer panel of the automotive panel are often encountered. Quality problems and surface problems are the key points and difficulties in mold debugging. In the later stage debugging process of the outer panel of the car panel, when the sheet material of the outer panel of the automobile panel is in contact with the ridge line of the convex die, when the sheet material begins to plastically deform at the ridge line of the convex die, the vicinity of the ridge ...

Problems solved by technology

In the later stage debugging process of the outer panel of the car panel, when the sheet material of the outer panel of the automobile panel is in contact with the ridge line of the convex die, when the sheet material begins to plastically deform at the ridge line of the convex die, the vicinity of the ridge line of the outer panel is often due to the impact on both sides. The force is not uniform, and the sheet material slides to generate a slip line, which will generate a slip line on the side of the ridge line of the outer panel of the automobile panel, especially on the ridge line of the fender, the ridge line of the front cover outer panel, and the upper and outer sides of the lift door. The ridgeline of the panel and the ridgeline of the outer panel on the back cover are common, refer to Figure 1 to Figure 4 As shown, this seriously affects the surface quality of the outer panel of the automobile panel
