Problems solved by technology

At present, the existing aluminum alloy swash plate is generally made of A390 hypereutectic aluminum-silicon alloy material. Although its room temperature strength and room temperature hardness meet the application requirements, its high temperature strength and high temperature hardness are poor, resulting in a low service life of the swash plate.
[0005] At present, the production process of the swash plate is mainly gravity casting, which has the following disadvantages: the structure density is low, which makes the swash plate easy to wear during work, the overall strength is not high, and it is easy to deform; The internal quality of the disc is poor, prone to breakage, jamming, etc., which wil

Abstract

The invention discloses a swash plate of an automobile air-condition compressor. The swash plate is prepared from an aluminium alloy comprising the following components in percentage by weight: 13-15% of Si, 4-5% of Cu, 0.2-0.3% of Mg, 0.8-1.5% of Ni, 0-0.1% of Mn, 0-0.5% of Fe, 0-0.1% of Zn, 0-0.2% of Ti, 0.1-0.3% of C, 0.1-0.3% of RE and the balance of Al. The invention further provides a production method of the swash plate of the automobile air-condition compressor. According to the production method provided by the invention, the high-temperature strength and the high-temperature hardness of the swash plate are improved, the cutting properties and the plasticity are improved, and low-cost production is realized by choosing and controlling elements in the aluminium alloy for the swash plate, and then replacing casting by forging, optimizing the pre-treatment and the post-treatment of the forging, and optimizing process parameters during the various treatment processes.
