Problems solved by technology

The material utilization rate of the above-mentioned processing technology is low, and the loss is large; the required molds are many, the scrap rate is high, and the processing cost is high; the inner diameter of the shell is poor (caused by the drawing stress and the wall thickness is thinned); the compressor is noisy (due to the stretched wall Thickness); products with the same inner diameter and different lengths only need to open different blanking dies and drawing dies; the bottom cover of the shell is integrated with the outer shell, and cannot be disassembled during the compressor test, which cannot meet customer assembly needs

Embodiment 1

[0013] The air-conditioning compressor shell processing technology of the present invention adopts the following process steps:

[0014] 1. Coiled plate is slitting, coiled and welded into high-frequency welded steel pipe; the inner diameter of the steel pipe is Φ121.56mm, the length of the steel pipe is 6m, and the wall thickness of the steel pipe is 2.9mm.

[0015] 2. Cut into the required high-frequency welded steel pipe, length: 100mm-300mm, deburring.

[0016] 3. Cleaning: Clean the steel pipe (heating and degreasing with degreasing agent), the purpose of cleaning is to remove oily impurities.

[0017] 4. Pickling: pickling the steel pipe (if you choose pickling board, do not pickling), the pickling medium uses hydrochloric acid aqueous solution with a concentration of not less than 15% (acidity 31 degrees), soaking for 15 minutes to oxidize the surface of the steel pipe The skin is all washed off.

[0018] 4. Expansion of the inner diameter of the casing: expand the ca...

Embodiment 2

[0026] The coil is slitting, rolled and welded into high-frequency welded steel pipe; the inner diameter of the steel pipe is Φ100.91mm, the length of the steel pipe is 6m, and the wall thickness of the steel pipe is 2.6mm. The air-conditioning compressor housing (cylinder) made by the production and processing technology in Embodiment 1 can meet the assembly requirements of users, has high material utilization rate, can increase the yield of finished products, and has small material loss; the inner diameter of the product has high precision and good roundness , and can reduce compressor noise.

Embodiment 3

[0028] The present invention adopts coiled plate slitting (pickling plate is selected instead of pickling), coiled and welded into a high-frequency welded steel pipe, the inner diameter of the steel pipe is Φ111.85mm, the length of the steel pipe is 6m, and the wall thickness of the steel pipe is 3.2mm. The air-conditioning compressor casing (cylinder) made by the production and processing techniques in Embodiments 1 and 2 can also meet the user's assembly requirements (the bottom cover is not welded).

Abstract

The present invention relates to process of forming casing for air conditioner compressor, and belongs to the field of machining technology. The process includes the steps of longitudinal shearing coiled plate, winding and welding to form high frequency welded steel pipe, cutting to required length, cleaning, pickling, expanding inner diameter, chamfering, shaping, making bottom cover, boxing and inspection. The present invention makes air conditioner compressor casing with high frequency steel pipe, and has high material utilizing rate, high product precision, capacity of lowering noise of the compressor and other advantages.

Description

technical field [0001] The invention relates to a molding process of an air-conditioning compressor shell (cylinder body), which belongs to the technical field of mechanical processing. Background technique [0002] The air conditioner compressor shell is mainly used to install the parts of the air conditioner compressor in the shell, and forms a closed cavity to store the compressor medium and lubricating fluid, etc., and is convenient for testing and transportation. In the prior art, deep drawing, cold drawing, and turning processes are usually used for processing air conditioner compressor shells, and the deep drawing process is the most common. The processing steps of the deep drawing process are as follows: the material selection is ST13, ST14 (pickling board). First cut the pickled flat plate into a square plate, then blank it into a round piece, and then go through one drawing, two drawing, shaping, third drawing, shaping, four drawing, shaping, trimming, chamfering,...
