Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.
It should be understood that the structures, proportions, and dimensions shown in the drawings and described herein are for illustrative purposes only and are not intended to limit the scope of the present invention, which is defined by the claims, but rather by the claims. In addition, the terms such as "upper", "lower", "left", "right" and "middle" used in the present specification are for convenience of description only, and are not intended to limit the scope of the present invention, and changes or modifications of the relative relationship thereof may be regarded as the scope of the present invention without substantial changes in the technical contents.
The invention provides a method for improving the surface quality near the edge line of an outer plate of an automobile covering part, which comprises the following steps: s1, determining the edge line of the sliding line of the outer plate of the covering part in the normal debugging process, and marking as the edge line 1 to be processed; s2, in the process of fine modeling of the outer plate of the covering part, carrying out strong pressure treatment near the ridge line 1 to be treated, wherein the strong pressure treatment area is in each Ymm range of two sides of the ridge line 1 to be treated, the strong pressure value is 0.1-0.12 mm, and Y is more than or equal to 8 and less than or equal to 12.
The surface quality improving method provided by the invention is characterized in that in the process of fine modeling during the manufacturing of the covering part outer plate, the ridge line of the covering part outer plate, which can generate the slip line, is subjected to forced pressing treatment, so that the problem that the slip line occurs in the ridge line of the covering part outer plate in the debugging process is solved. In the actual production process, the edge lines of the outer panel of the covering part, which are not processed by the surface quality improving method, are generally determined through a large number of debugging processes, so as to ensure that the edge lines of the outer panel of the covering part, which can generate the sliding lines, can be accurately found out, and the edge lines of the outer panel of the covering part, which can generate the sliding lines, are marked as edge lines 1 to be processed, which is shown in fig. 1 to 4.
In the fine modeling process of the outer plate of the covering part, the strong pressure treatment is carried out near the ridge line 1 to be treated, wherein the regions subjected to the strong pressure treatment are within Ymm (Y is more than or equal to 8 and less than or equal to 12) on two sides of the ridge line 1 to be treated, namely the regions with the width of 2Y taking the ridge line 1 to be treated as the center, and the strong pressure value is 0.1-0.12 mm.
