A kind of air conditioner bellows and its manufacturing method

Abstract

The invention relates to the field of air conditioner pipelines, in particular to an air conditioner bellows and a manufacturing method thereof. The air conditioner bellows comprises a bellows body, wherein the bellows body comprises a bellows section and polished rod sections; corrugated protrusions are arranged on the outer side of the bellows section and raised from the outer wall of the bellows section, wave crests of the corrugated protrusions are higher than the outer wall of the polished rod sections, and the diameters of circles on which wave troughs of the corrugated protrusions are positioned are the same as the diameters of the polished rod sections; the bellows section and the polished rod sections on the bellows body are manufactured into the bellows body in an integrated manner. According to the air conditioner bellows disclosed by the invention, defects that corrugations in a traditional bellows are concave inwards and the production technology of the traditional bellows is complex are overcome, and the air conditioner bellows provided by the invention is high in production efficiency and good in flow guiding effect. Besides the invention further provides the manufacturing method of the bellows, the manufacturing method comprises three steps of discharging and straightening, annealing and spreading, so that processing procedures are reduced, and the annealing time is shortened.

Description

technical field [0001] The invention relates to the field of air-conditioning pipelines, in particular to an air-conditioning corrugated pipe and a manufacturing method thereof. technical background [0002] Air conditioners generally need to be composed of an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are installed indoors and outdoors respectively, and are connected by pipelines and wires in the middle. The connecting pipeline is generally a pipeline of metal material. During the connection process, due to the needs of the installation location and the installation environment, especially in the occasions that need to pass through the wall, it is often necessary to bend the metal pipeline. It is difficult to bend the metal pipeline with the outer wall as a polished rod, and the deformation after bending is relatively large. It is large and affects the liquid flow in the pipe after installation. In order to ensure that the metal pipe is easy to b...
