Abstract
The invention discloses a method for producing an internal combustion engine piston, which belongs to the technical field of machinery manufacture. The method comprises the following steps: 1)preparing an internal combustion engine piston material; 2)performing modification treatment before casting the internal combustion engine piston; 3)casting the internal combustion engine piston; 4)performing fine treatment on the internal combustion engine piston; and 5)performing artificial aging treatment on the internal combustion engine piston. According to the invention, the method solves the problem that during the working process of the internal combustion engine piston, the cooperation of the internal combustion engine piston and a piston cylinder can be influenced by high thermal expansion coefficient of the piston. The method has the advantages of simple method, low cost and easy processing.
Description
Technical field
The invention belongs to machinery manufacturing technology field, more particularly, relate to a kind of Internal combusting piston processing and heat-treating methods.
Background technology
Oil engine is a kind of by the interior heat engine that can be converted into mechanical energy, and in the course of the work, after liquid or geseous fuel and air mixed, the high pressure combustion chamber burning outburst directly inputting cylinder interior produces power.Indoor at high-pressure combustion, piston becomes the main force transferring part in energy conversion process.Because the temperature of high-pressure combustion indoor, pressure are high, higher requirement are proposed to piston manufacture, not only will have good mechanical property, and can High Temperature High Pressure be born, and require that its thermal expansivity is lower, to avoid affecting and the coordinating of piston cylinder.
Summary of the invention
For existing internal combustion engine in the course of the work, thermal expansivity because of piston is high and affect the problem coordinated with piston cylinder, the invention provides a kind of manufacture method of internal combustion engine, carry out reasonable disposition by combustion motor piston material composition and carry out corresponding thermal treatment, its thermal expansivity is reduced, reduce piston distortion at high temperature, thus reach reduction high temperature to the object of the impact that piston coordinates with piston cylinder.
For solving the problem, the present invention adopts following technical scheme.
A manufacture method for internal combustion engine, comprises the following steps:
(1) preparation of internal combustion engine material:
The mass percent of internal combustion engine material component is: Si:11.0-13.0%, Mg:0.4-1.0%, Cu:1.0-2.0%, Mn:0.3-0.9%, and all the other are Al;
(2) Metamorphism treatment before internal combustion engine cast:
Alterant containing sodium is joined in the liquid alloy of internal combustion engine, Metamorphism treatment is carried out to it;
(3) casting of internal combustion engine:
Utilize permanent mold casting to complete the casting of combustion motor piston;
(4) precision work of internal combustion engine;
(5) the artificial aging process of internal combustion engine:
Internal combustion engine is heated to 950-980 DEG C, furnace cooling after the insulation sufficiently long time.
Preferably, in described step (1), the mass percent of internal combustion engine material component is: Si:12.0%, Mg:0.8 %, Cu:1.6%, Mn:0.6%, and all the other are Al.
Preferably, in described step (5), internal combustion engine is heated to 960 DEG C.
Compared to prior art, beneficial effect of the present invention is:
(1) the present invention carries out reasonable disposition by combustion motor piston material composition, and its thermal expansivity is reduced, and reduces piston distortion at high temperature.
(2) the inventive method is simple, and cost is low, handling ease.
