Embodiment 1

[0034] Embodiment 1, a method for controlling the paint film thickness of a car body color paint, first obtain the color paint spraying flow rate of a new batch of color paint through the following steps:

[0035] The first step is to paste the tin plate at the detection point of the corresponding color paint film thickness of the car body in the good product;

[0036] The second step is to cover the surface of the vehicle body with a protective film in the good product; the protective film is a plastic film.

[0037] The third step is to cut off the plastic protective film on the part of the good product that is coated with the tin plate;

[0038] The fourth step is to make the good intermediate-coated car body enter the painting line and spray the new batch of colored paint onto the tinplate plate according to the preset spraying flow rate of the colored paint;

[0039] The fifth step, tearing off the protective film on the intermediate-coated car body of the good product; ...

Embodiment 2

[0064] Embodiment two, see Figure 6 , the difference with Embodiment 1 is:

[0065] The water valve 8 includes a valve body 88 , a valve core 84 , a valve closing spring 85 and a spring support frame 86 . The valve body 83 is provided with a liquid flow channel 87 . The liquid flow channel 87 includes a conical section 871 and a cylindrical section 872 . The conical section 871 and the cylindrical section 872 are coaxial. The small-diameter end of the tapered section 871 is connected with the inlet 81 of the water valve. One end of the cylindrical section 872 is butted with the large-diameter end of the conical section 871 , and the other end penetrates to the outer surface of the valve body 88 to form the water valve outlet 82 . The spool 84 is located in the tapered section 871 . The spool 84 is tapered. The taper of the spool 84 is the same as that of the tapered section 871 . The spring support frame 86 is threadedly connected in the outlet 82 of the water valve. ...

Abstract

The invention relates to an automobile body paint spraying technology and an automobile production tool. A protection film covering tool comprises a rack, and the rack is provided with a pulling handle, a vacuum generator, a protection film winding supporting frame and a scraping pipe; a protection film adsorption gap extending in the axial direction of the scraping pipe is arranged on one side of the side wall of the scraping pipe, and dust adsorption holes are formed in the other end of the side wall of the scraping pipe; and the air inlet end of the vacuum generator is communicated with the scraping pipe. According to an automobile body color paint film thickness control method, a tinplate is fixed to the portion, corresponding to detection points, of a painted automobile body in a good product, and other portions are covered with a protection film to spray color paint and test a paint film thickness; according to the formula A1 is equal to A2+(H1-H2)*A2, the spraying flow of new-batch color paint is calculated, wherein the A2 is a color paint preset spraying flow, H1 is a needed color paint film thickness in the automobile production process, and H2 is the color paint film thickness on the surface of the tinplate. The method can effectively control the color paint film thickness, and cannot cause scrap of good automobiles, and convenience of protection film coverage can be improved.

Description

technical field [0001] The invention relates to a car body paint spraying process and tooling for automobile production, in particular to a method for controlling the thickness of a car body color paint film and a tool for covering and protecting the film. Background technique [0002] Automobile is a common means of transportation in daily life. The surface of the car body (hereinafter referred to as the car body) needs to be covered with a paint layer. The process steps for covering the surface of the car body with the paint layer are: applying primer, putty, intermediate paint and top coat in sequence. The top coat includes color paint and paint. Varnish over paint. In Chinese patent application number 2012102523546, the publication date is December 12, 2012, and the patent document titled "a stainless steel car body spraying process" promptly discloses a process for painting a car body. The color of the surface of the car body (that is, the color reflected by the c...
