Abstract

The invention provides an automobile air conditioner compressor planetary plate. The planetary plate is prepared from an aluminum alloy which comprises the following components in percentage by weight: 8%-9% of Si, 1%-1.5% of Cu, 0.4%-0.7% of Mg, 0.1%-0.3% of C, 0.8%-1.5% of Ni, 0-0.1% of Mn, 0-0.2% of Fe, 0-0.1% of Zn, 0.3%-0.4% of Ti, 0.1%-0.2% of RE and the balance of Al. The invention also provides a production method of the automobile air conditioner compressor planetary plate. The elements in the aluminum alloy for the planetary plate are selected and controlled, a forging technique is further used instead of the casting technique, the pretreatment before forging and after-treatment after forging are optimized, and the technological parameters in each treatment process are optimized, thereby enhancing the strength of the planetary plate and further improving the service performance and service life of the planetary plate.

Description

technical field [0001] The invention relates to the technical field of the automobile industry, in particular to a planetary disk of an automobile air-conditioning compressor and a production method thereof. Background technique [0002] With the continuous improvement of people's living standards, the demand for automobiles is increasing, and the requirements for automobile performance are also getting higher and higher, which leads to the rapid development of the domestic automobile industry and the continuous improvement of the localization of auto parts. [0003] The automobile air-conditioning compressor is the core component of the automobile air-conditioning system. The swash plate compressor is a reciprocating one-way piston structure that distributes five or seven cylinders evenly in the compressor cylinder. When the main shaft rotates, the planetary disk reciprocates in the axial direction, driving the compressor piston to reciprocate, thus completing the suction, ...
