Machining process of back plate for refrigerator compressor

Abstract

The invention discloses a machining process of a back plate for a refrigerator compressor. The process comprises steps as follows: a plate material for machining of the back plate for the refrigerator compressor is purchased, the purchased plate material is treated in a shape of rectangle, punching and chamfering treatment is performed, and scribing operation is performed; punching and tongue cutting are performed on the plate material along a scribing mark, and then edge folding is performed; edge pressing operation is performed on the plate material, and platen bending is performed; second bending operation and deburring are performed on the plate material, and the formed back plate is obtained and can be put in storage and delivered out of a factory after being checked qualified according to an unqualified product control program. Compared with existing machining processes, the machining process of the back plate for the refrigerator compressor has the advantages that the machining procedures are simple, operation is easy, the production and machining efficiency is high and the machining cost is low. By means of three checking procedures, the quality of the machined back plate for the refrigerator compressor and the qualification rate of the delivered back plates for the refrigerator compressors are strictly guaranteed, and the process is worth popularization.

Description

technical field [0001] The invention relates to the technical field of processing refrigerator spare parts, in particular to a processing technology of a back plate for a refrigerator compressor. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. The volume of household refrigerators is usually 20-500 liters. In 1910, the world's first household refrigerator with compression refrigeration came out in the United States; in 1925, Lido Company of Sweden developed a household absorption refrigerator; in 1927, General Electric Company of the United States developed a fully enclosed refrigerator; The air-cooled continuous diffusion absorption refrigerator was put on the market; the new refr...
