Problems solved by technology

The plate sample is pre-stretched first, then oiled on the surface, and then polished until the paint brush line appears. Because the metal plate has a certain gloss, the contrast of the paint brush line is low, and the professional quality of the polisher Higher, requires lighter grinding force, and it is easy to cause excessive grinding when the grinder's judgment is inaccurate

Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the drawings and specific implementation methods. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0028] In the following description, a lot of specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do it without departing from the meaning of the present invention. By analogy, the present invention is therefore not limited to the specific examples disclosed bel...

Abstract

The invention discloses a paint brush line display method which comprises the steps: coating the surface of a pre-stretched plate sample with colored ink, wherein the coating direction of the coloredink is parallel to the pre-stretching direction; coating lubricating oil on the surface of the completely dried colored ink; and repeatedly polishing the surface in a single pass until the paint brushline of the plate sample appears. It can be seen that according to the paint brush line display method, the surface of the pre-stretched sample plate is coated with a layer of colored ink firstly, then the surface of the pre-stretched sample plate is coated with lubricating oil, then polishing is conducted, in the polishing process, the colored ink in the protruding area where the paint brush line is located is polished, the area is brightened, and the colored ink in the concave area is not polished away, and the area is still dark so that the concave-convex area contrast is obvious, the paint brush line contrast and the display accuracy are improved, and due to the existence of colored ink, the polishing degree is easy to judge, excessive polishing is avoided, and the polishing difficulty is reduced.

Description

technical field [0001] The present application relates to the technical field of surface quality detection and analysis, in particular to a paint brush line display method. Background technique [0002] Lightweight, high-strength metal materials such as magnesium alloys, aluminum and their alloys are widely used in the automobile manufacturing industry. Due to some unfavorable factors or improper processing technology of these metal materials, concave and convex lines appear on the surface of the metal plate after stamping. A paintbrush line is formed. These concave-convex lines cannot be observed without special treatment before painting, and the paint cannot cover these concave-convex lines when they are transferred to the subsequent process, which is likely to cause waste products. [0003] At present, when the paint brush line is displayed and tested, it is carried out according to the paint brush line display method stipulated in the national standard "GB / T33227-2016 A...
