Method for remanufacturing waste outdoor unit support

Abstract

The invention discloses a method for remanufacturing a waste outdoor unit support. The method comprises the steps that recovery processing is carried out, specifically, the waste outdoor unit support is recycled and screened so as to remove impurities in the waste outdoor unit support; then the screened waste outdoor unit support is sheared through a shearing machine, and the sheared outdoor unit support is crushed through a crusher; grinding is carried out, specifically, surface treatment is carried out in a surface stripping machine so as to obtain a refined iron material; the iron material is molten down and remade, specifically, the recycled refined iron material is placed in a smelting furnace to be molten down, and a blank obtained after being molten down is remanufactured through a punching machine so as to form a support blank; heat treatment is carried out, specifically, the support blank is subjected to annealing treatment, the temperature is kept at 650-720 DEG C, the duration is 15 minutes, air cooling is carried out to reach the room temperature, and then the support blank is machined to obtain a finished blank; and rust-proof surface treatment is carried out, specifically, spray coating or roller coating is carried out on the surface of the support with rust-resistant paint. The method has the advantages that the rust-proof performance of the support can be effectively improved, and the service life of a product can be prolonged.

Description

technical field [0001] The invention relates to the field of air conditioner support manufacturing, in particular to a method for remanufacturing a waste external machine support. 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. Therefore, a large number of external machine brackets will be recycled after a certain number of years...

[0002] With the rapid development of modern society, 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 the 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 safety hazards

Therefore, a large number of external machine brackets will be recycled after a certain number of years of actual use, resulting in a large amount of scrap steel and damaging the environment
