Air conditioner external unit shell manufacturing and machining technology

Abstract

The invention relates to an air conditioner external unit shell manufacturing and machining technology. According to the technology, a workbench, a middle bending device, an upper end bending device and a left end bending device are included, wherein the middle bending device is mounted in the middle of the upper end of the workbench, the upper end bending device is arranged above the middle bending device, and the left end bending device is mounted on the left side of the middle bending device. According to the air conditioner external unit shell manufacturing and machining technology, the problems that when an air conditioner external unit shell is manually made, a to-be-bent sheet metal part is fixed firstly, and then is bend, in a bending process of the sheet metal part, a bending position is inaccurate, the sheet metal part and the bending device relatively slide, the quality of a bent shell is prone to being caused disqualified, and during manufacturing of existing air conditioner external unit shell manufacturing equipment, only one bending position on the sheet metal part can be bent each time, and manufacturing efficiency of the air conditioner external unit shell is reduced due to a tedious bending manufacturing process of the air conditioner external unit shell.

Description

technical field [0001] The invention relates to the technical field of air conditioner manufacturing, in particular to a manufacturing process for an air conditioner outer unit shell. Background technique [0002] The main functions of the external unit of the air conditioner are as follows: First, the air takes away the superheated part of the high-temperature air-conditioning refrigerant gas sent by the compressor, making it dry and saturated steam. The second is to carry out liquefaction under the condition of constant saturation temperature. The third is that when the air temperature is lower than the condensation temperature, the liquefied refrigerant is further cooled to the same temperature as the surrounding air to play a cooling role. The external unit of the air conditioner is hung outdoors for many years. It is exposed to the sun, rain, wind and dust, and is easily rusted and blocked by dust, which seriously affects the normal service life of the air conditioner....

AI Technical Summary

Problems solved by technology

[0004] (1) When bending the air-conditioning external unit casing by manual cooperation with machinery, the sheet metal parts to be bent are usually fixed manually first, and after the sheet metal parts are fixed, the sheet metal parts are manually or mechanically fixed. During the bending process of sheet metal parts, due to the unreliable manual fixation, it is easy to make the positioning of the bending position inaccurate and the relative sliding occurs between the sheet metal part and the bending device during bending, so that after bending The quality of the air conditioner external unit shell is unqualified;

[0005] (2) When the existing air-conditioner external unit casing manufacturing equipment is used to manufacture and process the air-conditioner external unit, it usually first clamps and fixes the sheet metal parts to be bent through the fixing mechanism. After the sheet metal parts are clamped and fixed, the air-conditioner The manufacturing equipment of the outer machine shell bends the sheet metal parts. When the existing air conditioner outer machine shell manufacturing equipment bends the sheet metal parts, it can only bend one bending position on the sheet metal part at a time, so that The bending process of the outer unit shell of the air conditioner is cumbersome, which reduces the production efficiency of the outer unit shell of the air conditioner
