Description

Technical Field

[0001] The invention relates to the technical field of heat treatment of castings, and in particular to heat treatment equipment for processing piston rings of air compressors. Background Art

[0002] Positive displacement air compressors directly rely on changing the volume of gas to increase gas pressure. As a type of positive displacement air compressor, the main compression element of the piston air compressor is the piston, which changes the gas volume by reciprocating in the cylinder. Therefore, the sealing between the piston and the inner wall of the cylinder directly affects the working performance of the air compressor, and a bad piston directly affects the sealing of the piston. Now the piston ring of the air compressor needs to be produced by casting in the production process. Casting is a metal forming object obtained by various casting methods, that is, the smelted liquid metal is injected into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling and subsequent processing such as grinding, the object with a certain shape, size and performance is obtained. After the piston ring is cast, the casting needs to be heat treated. During the heat treatment process, quenching is to heat and keep the workpiece warm, and then quickly cool it in a water medium. After quenching, the steel part becomes hard.

[0003] However, during the current heat treatment of castings, the castings are placed in a cooling pool for cooling. This will cause the cooling water around the castings in the cooling pool to heat up rapidly, and the surrounding cooling water cannot contact the workpiece in time for cooling, which reduces the subsequent cooling rate and causes uneven cooling, thereby affecting the material properties of the castings. Therefore, we propose a heat treatment equipment for air compressor piston ring processing to solve this problem. Summary of the invention
