Problems solved by technology

However, if the unglued gap is too large, for example due to insufficient precision of the machine, the outer edge of the vehicle flange needs to be glued separately manually
This slows down the work tempo and is very uneconomical

Embodiment Construction

[0023] figure 1 Front schematic view of a vehicle with side skirts showing the process of vehicle painting. The vehicle 1 includes a side skirt 2 on both sides. The side skirt 2 belongs to the vehicle flange. Herein, the term "vehicle flange" refers to a flange protruding outward from the vehicle on the outer periphery of the vehicle.

[0024] To paint the side skirts 2, Figure 2 to Figure 4 A preferred embodiment of the nozzle according to the invention is shown. first by figure 2 It can be seen that the gun nozzle includes two spray bodies 100, a connecting bridge 200 for connecting the two spray bodies and a connecting rod 300 for connecting the gun nozzle to a gun head (not shown) of a spray gun. For painting, the spray body 100 , the connecting bridge 200 and the connecting rod 300 can be connected to one another in a fluid-conducting manner. For example, the nozzle body 100 , the connecting bridge 200 and the connecting rod 300 can be hollow or comprise fluid-con...

Abstract

The invention relates to a PVC coating method which comprises a welded joint sealing step and a base plate sealing step. The welded joint sealing step includes coating PVC glue onto a vehicle body (1). The base plate sealing step includes coating the PVC glue onto a vehicle bottom. The PVC coating method is characterized in that the welded joint sealing step further includes coating the PVC glue onto a side skirt board (3) of the vehicle body (1) at the same time, especially the top face and bottom face of the edge. The invention further relates to a gun nozzle for a spray gun. The spray gun is particularly used for the PVC coating method.

Description

technical field [0001] The invention relates to a nozzle for painting vehicle flanges. Background technique [0002] In the vehicle manufacturing industry, an important process in the vehicle painting process is gluing. The gluing process generally includes a step of sealing the weld seam and a step of protecting the vehicle underbody, whereby in particular a sealing and corrosion protection of the vehicle can be achieved and thus, for example, wax can be prevented from escaping from the weld seam during the subsequent waxing of the cavities. [0003] In order to improve the airtightness, sound insulation, shock resistance, stone impact resistance, etc. of vehicles, PVC coatings are widely used in the vehicle gluing process. PVC coatings usually refer to polyvinyl chloride coatings, the main component of which is polyvinyl chloride resin. By adding pigments, plasticizers, fillers, etc. to polyvinyl chloride resin for mixing, a high-solid content coating with a solid content...
