Tank body processing method

Abstract

The invention discloses a tank body processing method, comprising steps of: cutting, wherein a sheet material is cut to be a small square material according to a required size; welding, wherein the stress of the small square material is removed, and then the small square material is rolled into a circular shape, a rolling and butting quantity of the small square material is adjusted via a Z-shaped guide rail, and then the adjusted small square material is welded into a drum shape; recoating, wherein inside and outside of a weld joint are covered by a coating; drying, wherein the coating which is covered on the weld joint is solidified via a U-shaped furnace; necking, wherein an end part of the tank body is processed to have a necking part by a necking mould; flanging, wherein two ends of the tank body are flanged by a flanging mould; sealing, wherein the two ends of the tank body are sealed via a mould. The tank body processing method provided by the invention can improve processing yield, processing quality and compression strength of the tank body.

Description

technical field [0001] The invention relates to packaging container processing technology, in particular to a can body processing method. Background technique [0002] At present, three-piece cans are more commonly used metal packaging containers on the market. The existing three-piece cans are made of ordinary tinplate materials, including the barrel-shaped main body of the can body and the two ends connected to the main body of the can body. For the top cover and the bottom cover, the wall thickness of the main body of the tank body processing method is 0.2-0.25mm. [0003] Due to the rise in raw material prices, the price of tinplate materials has risen sharply. In the case of a substantial increase in material costs, the only way to reduce material costs is to reduce the thickness of the tank without reducing the capacity of the tank. However, due to the thickness of the tank Reduced, under the conditions of the existing tank body processing method, it is impossible to ...

Problems solved by technology

[0003] Due to the rise in raw material prices, the price of tinplate materials has risen sharply. In the case of a substantial increase in material costs, the only way to reduce material costs is to reduce the thickness of the tank without reducing the capacity of the tank. However, due to the thickness of the tank Reduced, under the conditions of the existing tank body processing method, it is impossible to process a tank body with a thinner thickness. Low, the tank body is easily deformed, and the tank body is easily damaged during processing, the yield is low, and the existing process needs to be improved
