Embodiment 1

[0039] Such as figure 1 Shown, the embodiment of the present invention provides a kind of method of spraying automobile cover part, and this method comprises:

[0040] In step 201: surface treatment is performed on the first automobile cover to obtain a smooth and clean second automobile cover;

[0041] In step 202: performing surface treatment on the surface of the second automobile cover to enhance the adsorption capacity, improving the adsorption capacity of the second automobile cover to paint, and obtaining a third automobile cover;

[0042] In step 203: spraying paint on the surface of the third automobile panel to improve the apparent quality of the third automobile panel to obtain a fourth automobile panel.

[0043] The present invention enhances the adsorption ability of the surface of the second car cover to the paint by performing surface treatment to enhance the adsorption capacity of the second car cover, so that the paint can be effectively adsorbed on the surfa...

Embodiment 2

[0065] Such as figure 2 As shown, a method for spraying automobile panels provided by the embodiment of the present invention is used for spraying automobile panels made of carbon fiber composite materials, including:

[0066] In step 301, the surface of the first car cover is polished, and the polished part of the first car cover is cleaned with fine mist water flow during the grinding process to obtain a fifth car cover with a smooth surface.

[0067] Wherein, the grinding of the surface of the first automobile cover needs to be carried out in a confined space, and before grinding, the first automobile cover needs to be fixed on the inner bushing, the surface of the first automobile cover is kept on the top, and there is no If any part is blocked, then use a water gun to rinse the surface of the first car cover to remove the dust on the surface of the first car cover, and then use a dry cloth to wipe off the water on the surface of the first car cover. During the grinding ...

Abstract

The invention discloses an automobile covering element spray coating method, and belongs to the field of automobile part manufacturing. The method comprises the following steps that a first automobile covering element is subjected to surface treatment to obtain a second automobile covering element with the smooth and clean surface; the surface of the second automobile covering element is subjected to surface treatment for enhancing the adsorption capability, the adsorption capability of the second automobile covering element on the paint is improved, and a third automobile covering element is obtained; the paint is sprayed and coated on the surface of the third automobile covering element to obtain a fourth automobile covering element. The automobile covering element spray coating method has the advantages that the second automobile covering element is subjected to the surface treatment for enhancing the adsorption capability, so that on the basis that the paint can be effectively adsorbed onto the surface of the third automobile covering element, the surface depression of the third automobile covering element can be filled through increasing the thickness of the paint, the puttying or the lime scraping is avoided, the spray coating schedule is accelerated, and the whole spray coating operation period is shortened, so that the method can be applied to large-scale automobile spray coating processing, and the current automobile large-scale production requirements are met.

Description

technical field [0001] The invention relates to the field of automobile parts manufacturing, in particular to a method for spraying automobile covering parts. Background technique [0002] Automobile panels refer to auto parts that make up the car body and cover the car engine and chassis. In order to obtain car panels with excellent appearance quality, it is necessary to spray the surface of the car panels. [0003] Existing methods for spraying the surface of automobile panels include surface treatments such as grinding, static removal, and dust removal on the surface of automobile panels, and steps such as spraying primer, scraping putty, scraping dust, and spraying paint on the automotive panels. Among them, scraping putty and scraping dust is to remove the uneven part of the surface of the car cover by filling or overall treatment after the primer is sprayed on the surface of the car cover, so that the surface of the car cover is smooth and smooth, so that the paint can...
