Description

Technical Field

[0001] The present application relates to the technical field of automobile parts processing, and in particular to a surface strengthening device for a dynamic plate of an automobile compressor. Background Art

[0002] The moving plate in the automobile compressor is one of the core components of the scroll compressor. Its working principle is based on the relative meshing movement of the moving plate and the stationary plate. The moving plate is an eccentric gyroscopic translational involute type, interacting with the fixed involute stationary plate. Through this relative movement, the closed volume is continuously changed to achieve the purpose of compressing the gas. This continuous compression process makes the scroll compressor widely used in air conditioning, refrigeration, general gas compression, automobile engine superchargers and vacuum pumps.

[0003] The rotor plate is subjected to repeated stretching, compression and friction during the operation of the compressor, which can lead to thermal fatigue and surface loss. Therefore, the surface strength of the rotor plate is directly related to its wear resistance, thermal fatigue resistance and service life. Especially in high-speed automobile air-conditioning compressors, the surface strength of the rotor plate can effectively reduce vibration, reduce noise, and improve the efficiency and life of the compressor.

[0004] In the prior art, the surface strength of the moving disk is usually improved by surface composite method, such as adding different contents of ceramic strengthening phases through laser cladding technology to prepare medium entropy alloy Ni-Co-Cr composite coating to improve wear resistance, toughness and thermal fatigue resistance. In practical applications, the surface composite strengthening method has the following shortcomings: 1. Due to different phase compositions, there is inevitably a microscopic bonding interface between the composite strengthening layer and the matrix. Under repeated tension, compression and friction, the composite strengthening layer and the matrix will experience microscopic interface tearing and displacement, resulting in the shedding of the composite strengthening layer; 2. It is difficult to achieve microscopic uniform distribution of the strengthening phase, and the inevitable local clusters and segregation will lead to obvious hardness differences in the microstructure. Although the overall surface strength is improved in the short term, the complex and changeable service process will lead to uncontrollable surface strength deterioration due to local differences in the microstructure; 3. The requirements for process and equipment precision are high, the manufacturing cost is high, and the process cycle is long, which limits its application in large-scale production.

[0005] Therefore, how to improve the surface strength of the dynamic plate of automobile compressors while ensuring the micro-uniformity of surface strength, improve process efficiency and reduce process costs remains an important research direction in this field. Summary of the invention
