Problems solved by technology

At present, the existing aluminum alloy swashplates are generally made of A390 hypereutectic aluminum-silicon alloy material, which has poor high-temperature strength and high-temperature hardness; at present, the production process of swashplates is mainly gravity casting, and the cast product has a low structure density. As a result, the product is not wear-resistant, the overall strength is not high, and it is easy to deform, etc.; in addition, the casting process is prone to shrinkage, cold insulation, etc., resulting in internal stress in the product, easy fracture and seizure, and low dimensional processing accuracy.

Abstract

The invention discloses an automobile air-conditioning compressor swash plate. The automobile air-conditioning compressor swash plate is prepared from the following component aluminum alloys in percentage by weight: 10%-12% of silicon, 3%-4% of copper, 0.2%-0.3% of magnesium, 0.6%-1.2% of nickel, 0-0.2% of manganese, 0.2%-0.4% of molybdenum, 0-0.4% of iron, 0-0.1% of zinc, 0.2%-0.6% of chromium, 0-0.2% of titanium, 0.1%-0.2% of carbon, 0.2%-0.4% of rhenium, and the balance of aluminum. A production method of the automobile air-conditioning compressor swash plate comprises the steps that step one, preheating is carried out; step two, gold melting is carried out; step three, deterioration is carried out; step four, heat treatment is carried out; step five, rough machining is carried out; step six, cryogenic nitrogen treatment is carried out; and step seven, finish machining is carried out. According to the Automobile air-conditioning compressor swash plate and the production method thereof, the tissue density of products can be enhanced, the abrasive resistance and strength of the products are improved, transformation of the products is avoided, internal stress of the products is eliminated, the life is prolonged, and the actual use requirement is met.

Description

technical field [0001] The invention relates to a swash plate of an automobile air-conditioning compressor and a production method thereof, belonging to the technical field of automobile parts. Background technique [0002] Automobile air-conditioning compressor is the heart of the automobile air-conditioning refrigeration system, which plays the role of compressing and transporting refrigerant vapor; compressors are divided into two types: non-variable displacement and variable displacement. Among them, the displacement of the fixed-displacement compressor increases proportionally with the increase of the engine speed. It cannot automatically change the power output according to the cooling demand, and has a relatively large impact on the engine fuel consumption. Its control is generally By collecting the temperature signal of the air outlet of the evaporator, when the temperature reaches the set temperature, the electromagnetic clutch of the compressor is released, and the...
