Problems solved by technology

The traditional internal galvanizing process of the fuel tank is to first coat the fuel tank panel with a zinc alloy coating, then slice it into pieces, and then weld it into a whole fuel tank. In this way, the zinc alloy coating on the weld part is oxidized and damaged due to high temperature burning during the welding process. , affecting the corrosion resistance inside the tank, and will seriously shorten the service life of the tank

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The invention relates to a coating processing method for the inner wall of an oil tank. Firstly, the oil tank is integrally welded, and then the inner wall of the oil tank is subjected to barrel plating of a zinc alloy coating, wherein the barrel plating step of the zinc alloy coating is carried out in a turning device. After the welding process of the whole tank, the surface treatment of the inner wall of the fuel tank is carried out first, and impurities such as oxide skin and rust on the inner surface of the fuel tank are removed by chemical pickling method, after pickling for 10 to 15 minutes, the inside is washed twice with clean water, and then the following steps are carried out: Barrel plating steps of zinc alloy coating:

Abstract

The invention relates to a method for processing a plating layer on the inner wall of an oil tank, which comprises a barrel plating step for a zinc alloy plating layer after an integral tank welding step, wherein the barrel plating step is performed in a turnover device. The other scheme of the invention discloses the turnover device for barrel plating. The method for integral tank welding and barrel plating of the zinc layer overcomes veneer zinc plating and assembly welding on the inner wall of the oil tank in the traditional method, avoids damage to the zinc plating layer at a seam part during welding, enhances the corrosion resistance of the inner wall of the oil tank, and prolongs the service life of the oil tank.

Description

technical field [0001] The invention belongs to the field of processing and manufacturing, and more specifically relates to a coating processing method for the inner wall of a vehicle fuel tank and a device used in the coating processing process. Background technique [0002] In the processing and manufacturing of vehicle fuel tanks, especially in the production and manufacturing process of vehicle fuel tanks such as excavators, in order to strengthen the internal corrosion resistance and corrosion resistance of the substrate, a layer of zinc alloy protective coating is coated on the inner wall of the fuel tank. The traditional internal galvanizing process of the fuel tank is to first coat the fuel tank panel with a zinc alloy coating, then slice it into pieces, and then weld it into a whole fuel tank. In this way, the zinc alloy coating on the weld part is oxidized and damaged due to high temperature burning during the welding process. , which affects the corrosion resistan...
