Abstract

The invention provides a thermal spraying method for an engine piston ring, and belongs to the technical field of piston rings. The thermal spraying method for the engine piston ring comprises the following steps that S1, the two sides of the middle of a piston ring are clamped, clamping equipment is used for clamping the two sides of the middle, right opposite to a piston ring notch, of the piston ring to fix the piston ring; S2, preheating is conducted, specifically, the piston ring is preheated through preheating equipment to ensure that the piston ring is heated to a proper temperature; and S3, first thermal spraying is conducted, specifically, the outer surface, except for a clamped part, of the piston ring is sprayed with a high-strength wear-resistant composite coating with a certain thickness through spraying equipment. The two sides of the middle of the piston ring and the two sides of the notch end of the piston ring are sequentially clamped through the clamping equipment, the step of manually assisting in replacing the clamped part of the piston ring is omitted, the spraying time and the labor intensity of people are reduced, meanwhile, the spraying precision and quality can be improved, rapid thermal spraying is facilitated, the strength and abrasion resistance of the piston ring are improved, and the quality of an engine is improved.

Description

technical field [0001] The present application relates to the field of piston rings, in particular to a thermal spraying method for engine 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 can be used to seal the combustible gas mixture in the combustion chamber; the oil ring is used to scrape off the excess oil on the cylinder. The current thermal spraying method for engine piston rings has low thermal spraying efficiency, and it is necessary to manually replace the clamping position many times during the spraying process. Spraying the surface of the piston ring not only increases the spraying time and labor intensity of people, but also reduces the spraying accuracy and spraying quality after changing the clamping position many times, which is not conducive to the rapid progress of thermal spraying. [0003] How to invent a...
