Abstract
The invention discloses a manufacturing process of a piston ring. The piston ring which is machined by the process is an inclined lap type piston ring and comprises the following manufacturing steps of forging, rough turning, solution treatment, semi-finish turning, aging treatment, two end face grinding, opening and lap line ripping, opening and lap milling, lap clamping and finishing, fine turning, end face groove line ripping, end face groove flushing, clamping work, laser strengthening treatment, laser strengthening, gold machining and laser strengthening. The manufacturing process of the piston ring has the advantages that the processing is easy, the cost is low, and the mass production is easy; the problems that after the piston ring is worn, the opening gap is increased, and the sealing property is reduced are solved, the service life of the piston ring is prolonged, and the sealing property of the piston ring is improved.
Description
Technical field
The present invention relates to a kind of manufacture craft of piston ring, belong to the accessory technical field of all kinds of engines.
Background technology
Piston ring is parts crucial in the equipment such as internal combustion engine, air compressor machine, directly determines the important quality such as power, the discharge characteristic of internal combustion engine, air compressor machine.The piston ring that engine uses at present, owing to there being an opened gap in end, in use all exists after the wearing and tearing of piston ring body, and opened gap increases causes the sealing of cylinder to decline, and affects the power performance of engine and the problem of economic performance.Thus, someone has proposed a kind of two ends place by piston ring body and has made oblique lap mouth, increases the scheme of the sealing property of cylinder with this.But the piston ring difficulty of processing of this structure is large, cost of manufacture is high, can not mass production.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: proposed one and be easy to suitability for industrialized production, the manufacture craft of the piston ring that cost of manufacture is low.
Technical solution of the present invention is achieved in that a kind of manufacture craft of piston ring, with the piston ring of this processes be oblique lap mouth formula piston ring, comprise following making step: forging → rough turn → solution treatment → half finish turning → Ageing Treatment → grinding both ends of the surface → scratch mouthful and take mouthful line → milling opening and take mouthful → pincers are repaiied and taken mouth → finish turning → stroke end face line of rabbet joint → wash end face groove → pincers worker → laser reinforcing processing → thermal finalization → metalworking → final inspection.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The manufacture craft of piston ring of the present invention, has handling ease, with low cost, is easy to the advantage of mass production, has solved after piston ring scuffing, and opened gap increases, and the problem that sealing property declines has improved service life and the sealing property of piston ring.
Detailed description of the invention
The manufacture craft of a kind of piston ring of the present invention, with the piston ring of this processes be oblique lap mouth formula piston ring, comprise following making step: blank forging, rough turn cylindrical, solution treatment, half fine turning outer circle, Ageing Treatment, grinding both ends of the surface, scratch mouthful and take a mouthful line, milling opening and take mouthful, pincers repair and take mouth, finish turning, stroke end face line of rabbet joint, wash end face groove, pincers worker, laser reinforcing processing, thermal finalization, metalworking, final inspection.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (1)
