Abstract
The invention discloses an automobile air-conditioning compressor piston production method which adopts alloy steel materials. The method is characterized by including that the alloy steel materials are formed in a die through cold heading and cold pressing, formed pistons are subjected to finish machining to reach the standard size through a machining center, and surfaces of the pistons are subjected to carburizing treatment. The alloy steel materials are composed of, according to 100 weight parts, 0.30 to 0.50 part of carbon, 0.45 to 0.90 part of manganese, 0.05 to 0.40 part of silicon, 0.70 to 1.50 parts of aluminum nitride, 0.30 to 0.50 part of nitrogen boronate and the balance iron. The automobile air-conditioning compressor piston is obtained by means of cold heading and cold pressing of the alloy steel materials, application of the cold heading technique in production of automobile air-conditioning compressor pistons is guaranteed, industrial production is realized, internal cracks and sand holes are avoided through metallographic test and X-ray test, the product percent of pass reaches 99.9%, production cost is greatly lowered, and precision and quality of products are guaranteed.
