Anti-rust air conditioner bracket machining process

Abstract

The invention discloses an anti-rust air conditioner bracket machining process. The process comprises the following steps of selecting a material; selecting a 304 stainless steel plate as a blank; conducting heat treatment; conducting solution treatment on the selected steel plate, keeping the temperature at 1050 DEG C for 15 min and then conducting quick cooling; conducting hot-rolling forming onthe steel plate to obtain a bracket rough blank and conducting quick cooling after removing an oxide skin; conducting machining; conducting finish machining on the bracket rough blank to obtain a bracket with the complete appearance; preparing an oxide layer; putting the manufactured bracket into an acid solution to be soaked for 30 min or more and finally taking out and washing the bracket; conducting anti-rust surface treatment; conducting spraying or roller coating on the surface of the oxide layer by means of anti-rust paint and spraying polyurethane varnish onto the surface of the anti-rust paint three times. By means of the process, the anti-rust performance of the bracket is effectively improved, and the service life of products is prolonged.

Description

technical field [0001] The invention relates to the field of air-conditioning bracket manufacturing, in particular to a processing technology for anti-corrosion air-conditioning brackets. Background technique [0002] With the rapid development of modern society, scientific and technological progress has brought great convenience to people's lives. For example, in hot summer, air conditioners have become an indispensable part of urban life, but most of the old floors are not designed with special The air conditioner external unit is placed on a platform, so most of the air conditioner external units are installed on the wall by nailing the triangular external unit bracket made of metal. However, after five to eight years of use, these triangular external machine brackets will produce a lot of rust, and the structure will no longer be stable, thus causing potential safety hazards.
