Embodiment Construction

[0014] The present invention will be further described below:

[0015] The present invention comprises the following steps:

[0016] (4) Turning or milling the steel parts into piston ring components;

[0017] (5) spray reinforcement material coating on the piston ring assembly;

[0018] (6) A wear-resistant rubber sealing ring is placed on the piston ring assembly; an automobile engine piston ring is obtained.

[0019] Preferably, the reinforcing material coating in the step (2) is a material layer formed by mixing Ti(C,N)20%-Ni40%-WC10%-CrC10% powders in proportion.

[0020] Further, the wear-resistant rubber sealing ring in the step (3) is made of natural rubber, nitrile rubber, zirconia, acrylic resin, alumina superfine powder, silicon carbide grains, sodium hydroxide, carbon fiber, xylene , polyamide polyethylene glycol, acrylic acid, and acrylic ester are heated and mixed, then cooled and solidified.

[0021] Preferably, the material for making the wear-resistant rub...

Abstract

The invention discloses an automobile engine piston ring manufacturing process. A steel part is made into a piston ring component by turning or milling; the piston ring component is coated with a reinforcing material coating by spray coating; an abrasion-resistant rubber seal ring sleeves the piston ring component to obtain an automobile engine piston ring. Compared with the prior art, by spray coating of the piston ring component with the reinforcing material coating, high abrasion resistance of the piston ring component is realized. In addition, the seal ring made of a high-abrasion-resistance high-temperature-resistant material sleeves the piston ring component to further improve air tightness of the piston ring component, low friction is realized, air tightness of the piston ring component can be improved, engine power is guaranteed, and a popularization and application value is achieved.

Description

technical field [0001] The invention relates to a manufacturing technology of automobile parts, in particular to a manufacturing process of a piston ring of an automobile engine. Background technique [0002] Piston rings are widely used in various power machinery, such as steam engines, diesel engines, gasoline engines, compressors, hydraulic machines, etc., and are widely used in automobiles, trains, ships, yachts, etc. Generally, the piston ring is installed in the ring groove of the piston, and it forms a chamber with the piston, cylinder liner, cylinder head and other components to do work. In the prior art, most of the piston rings are made of metal, while the cylinder block of the engine is made of metal, and the friction between the metal and the metal is relatively large, which reduces the service life of the engine piston rings and reduces the engine piston The airtightness of the cylinder reduces the engine power, so there is room for improvement.
