Abstract

The invention relates to a method for manufacturing a 30-ounce disposable gas cylinder, in particular to a method for gas replacement before brazing of a small-scale gas cylinder. According to the method for the gas replacement before the brazing of the small-scale gas cylinder, after a bottle body is assembled, inert gases are added into the bottle body for the gas replacement technology before the assembled bottle body is placed on a high-temperature resistant band chain of a bottle feeding zone of a channel type environment protecting brazing furnace. According to the method for the gas replacement before the brazing of the small-scale gas cylinder, the bottle body is prevented from detonation caused by mixture of gas inside the bottle and gas inside the furnace in the process of brazing, so that scrapping of the bottle body and times of fault shutdown of a brazier are reduced and the percent of pass of product production and production efficiency are improved.

Description

technical field

[0001] The invention belongs to the technical field of processing small gas cylinders, and in particular relates to a manufacturing method of a 30-ounce disposable gas cylinder. Background technique

[0002] 30-ounce disposable gas cylinders are widely used abroad, and the most basic requirement for a production line is about 100,000 per month. The welding process of disposable gas cylinders in the prior art is completed in a continuous reducing protective atmosphere brazing furnace, such as figure 1 As shown, the specific operation method is as follows: place the assembled bottle body on the high temperature resistant mesh belt chain in the bottle feeding area, and place anti-rolling pads on the mesh belt chain, and hang the brazed part on the bottle body Oxygen-free copper wire required for brazing. The bottle body on the high-temperature-resistant mesh belt chain slowly enters the tunnel furnace body along with the driving wheel of the mesh belt chain, a...
