Processing Technology of Engine Metal Piston Ring

Abstract

The invention relates to the technical field of processing metal piston rings, and discloses a processing technology for metal piston rings of an engine, comprising the following steps: manufacturing an inlay groove on the outside of the gas ring of the engine piston ring, snapping and installing a piston ring assembly inside the piston ring assembly, the piston ring A wear-resistant rubber sealing ring needs to be installed on the outside of the component, and finally the outside of the installed sealing ring is sprayed with a coating of reinforcement material. The processing technology of the metal piston ring of the engine uses high-carbon steel as the raw material, which can be better installed inside the inlay groove. Compared with the traditional metal piston ring, the piston ring can better interact with the inner wall of the piston. It fits well and maintains a good sealing effect, which improves the flexibility of the piston ring's up and down movement. At the same time, the piston ring assembly can be cleaned after grinding. The metal ring after cleaning in metal cleaning agent can avoid oil pollution Rust occurs after long-term immersion, resulting in a decrease in service life.

Description

technical field [0001] The invention relates to the technical field of metal piston ring processing, in particular to the processing technology of engine metal piston rings. Background technique [0002] Piston rings are metal rings used to embed in piston grooves. Piston rings are divided into two types: compression rings and oil rings. The compression ring is used to seal the combustible mixture in the combustion chamber; the oil ring is used to scrape excess oil from the cylinder. The piston ring is a metal elastic ring with a large outward expansion deformation, which is assembled into the corresponding annular groove of the section. The reciprocating and rotating piston rings rely on the pressure difference of gas or liquid to form a seal between the outer circular surface of the ring and the cylinder and one side of the ring and the ring groove. [0003] However, when the engine piston in the traditional situation moves up and down, the internal piston ring will grad...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides the processing technology of the metal piston ring of the engine, which has the advantages of reducing the processing cost and improving the use effect of the piston ring, and solves the problem of the internal piston ring when the engine piston moves up and down in the traditional situation. It will gradually become unfit with the movement of the piston, resulting in a decline in the use of the engine. At the same time, the general engine piston ring processing process is complicated, resulting in an increase in processing costs, which is not conducive to ensuring the mass processing efficiency of piston rings.
