Manufacturing method of aluminum gas storage tank for subway vehicle brake system

Abstract

The invention discloses a manufacturing method of an aluminum gas storage tank for a subway vehicle brake system. The method comprises the following steps: step 1, weighing of aluminum alloy raw materials; step 2, melting of an alloy; step 3, aluminum alloy refining; step 4, forming of a casting mold; step 5, welding and molding; step 6, molding. In the step 1, silicon, copper, magnesium, titanium, chromium, manganese, a refining agent and aluminum raw materials are weighed in proportion; in the step 2, a melting boiler is selected, and the pure aluminum ingot raw material weighed in the step1 are fed into the melting boiler; a tank body is formed in a casting mold mode, so that the problem that the firmness of an integral gas storage tank is influenced due to the fact that a traditionalgas storage tank is manufactured in a welding mode and the welding surface is large is solved; and according to the aluminum alloy material of the gas storage tank, raw materials such as titanium, chromium, manganese, refining agents and the like are added, so that the tensile strength and the ductility of the finished gas storage tank are improved, and the gas storage tank can bear static load and impact load.

Description

technical field [0001] The invention relates to the technical field of manufacturing an air storage tank, in particular to a method for manufacturing an aluminum air storage tank used in the braking system of a subway vehicle. Background technique [0002] The subway is a fast, large-capacity, and electric traction rail transit built in the city; the train runs on a fully enclosed line, and the lines located in the central urban area are basically located in underground tunnels, and the lines outside the central urban area are generally located in viaducts Or on the ground, the subway is a proprietary, high-density, high-capacity urban rail transit system covering all kinds of underground and above-ground road rights in urban areas; the braking system of subway vehicles is often performed pneumatically, so that the gas storage tank is a subway The main components on the system, the air storage tanks used in the braking system of traditional subway vehicles are mostly aluminu...

Problems solved by technology

[0002] The subway is a fast, large-capacity, and electric traction rail transit built in the city; the train runs on a fully enclosed line, and the lines located in the central urban area are basically located in underground tunnels, and the lines outside the central urban area are generally located in viaducts Or on the ground, the subway is a proprietary, high-density, high-capacity urban rail transit system covering all kinds of underground and above-ground road rights in urban areas; the braking system of subway vehicles is often performed pneumatically, so that the gas storage tank is a subway The main components on the system, the air storage tanks used in the braking system of traditional subway vehicles are mostly aluminum alloys, which makes the finished product bearing strength and corrosion resistance relatively average; the traditional aluminum air storage tanks are made of steel plates after cutting , rolled, welded cylinder body, and two calendered heads are welded; the welding surface of the traditional gas storage tank is relatively large, which affects the firmness of the overall gas storage tank; therefore, a kind of brake for subway vehicles is designed. The method of making the system's aluminum gas storage tank is very meaningful
