Problems solved by technology

[0003] When an existing thermal spraying device for the production of engine piston rings is used, an electric arc is generated between two welding wire-like metal materials, and the heat generated by the arc causes the metal welding wire to gradually melt, and the molten part is sprayed to the surface by the compressed air flow. However, the spraying material in the above method must be conductive welding wire, so only metal can be used instead of ceramics, which reduces the anti-scratch performance of the coating and the friction and wear performance of the piston ring.

Abstract

The embodiment of the invention provides a thermal spraying device for engine piston ring production, and belongs to the technical field of machine manufacturing. The thermal spraying device for engine piston ring production is characterized in that a spray head is arranged in a working cabin; a control cabinet, a powder feeder, a gas cylinder and a heat exchanger are all arranged on one side of a shell; an air compressor is mounted in an equipment cabin; a main supporting mechanism is mounted in the working cabin and used for controlling the position of a piston ring; an auxiliary supporting mechanism is mounted in the working cabin; and the auxiliary supporting mechanism is used for replacing the main supporting mechanism.According to the thermal spraying device for engine piston ring production, provided by the embodiment of the invention, metal powder and ceramic powder can be melted, accelerated and sprayed to a base body material to form a coating, various materials can be sprayed, and the scratch resistance of the coating and the frictional wear performance of the piston ring are obviously improved.

Description

technical field [0001] The present application relates to the technical field of mechanical manufacturing, in particular to a thermal spraying device for production of engine piston rings. Background technique [0002] Piston rings are key components in internal combustion engines. Piston rings are in direct contact with high-temperature and high-pressure gas. Abrasion causes scratches or even seizure, and carbon deposits caused by incomplete combustion and abrasive debris formed during friction and wear will also aggravate the abrasive wear between the piston ring and the cylinder liner. Therefore, the coating on the surface of the piston ring The requirements for wear resistance are getting higher and higher, and the thermal spraying technology has flexible process and large coating thickness, which was once considered to be the best choice for future high-load internal combustion engines. [0003] When an existing thermal spraying device for the production of engine pist...
