Description

The processing method on cylinder sleeve of automobile engine surface
Technical field
The present invention relates to cylinder sleeve of engine manufacturing technology field, especially a kind for the treatment of side for cylinder sleeve of automobile engine Method.
Background technology
The abbreviation of cylinder sleeve i.e. cylinder sleeve of engine, it is set in the cylinder barrel of cylinder body, and combustion is collectively constituted with piston and cylinder cap Burn room.Its quality condition has been largely fixed the overhaul life of engine.The working environment of engineering truck is severe, Many dust on building site, the working speed amplitude of variation of engine is big, easily causes the serious wear of cylinder sleeve, and the life-span is shorter.To solve Above mentioned problem, improves the wearability of cylinder sleeve, and method general at present is that the cylinder liner blank of casting is laggard by roughing Row improves the hardness of inner surface of cylinder liner using quenching process such as high frequency, laser, salt baths, is then finished, by cylinder sleeve Inner surface reduces its surface roughness by means such as honing, polishings.But these technological means are mainly raising inner surface of cylinder liner Hardness, improve hardness and, but by improve hardness improve wearability amplitude be limited.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of cylinder sleeve of automobile engine that can extend cylinder sleeve service life The processing method on surface.
The technical proposal for solving the technical problem of the invention is：The treatment side on this cylinder sleeve of automobile engine surface Method, cylinder sleeve of automobile engine is made up of the raw material of following weight portion：C is that 2.6 parts~3.2, Si is 1.6~2.2 parts, and Cu is 0.6 Part~1.2 parts, Mn is 0.4 part~0.8 part, and Cr is 0.5 part~1.0 parts, and Ni is 0.6 part~1.2 parts；
Comprise the following steps：
A, the cylinder sleeve to completing endoporus finishing processing carry out high-frequency quenching, and the frequency of high-frequency quenching is 200KHz~250KHz, firmly It is 40HRC~45HRC to spend, and the thickness of hardened layer is 1.0 millimeters~2.5 millimeters；
B, the endoporus to the cylinder sleeve of completion high-frequency quenching carry out Honing process；
C, the cylinder sleeve to completing inner bore honing processing carry out vulcanizing treatment, and the curing temperature of vulcanizing treatment is 165 DEG C -185 DEG C, is protected The warm time is 2 hours, and sulfuric horizon thickness is 0.001 millimeter~0.005 millimeter.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：Due to this automobile hair Motivation cylinder sleeve is made up of the alloy wear-resisting cast iron containing C, Si, Cu, Mn, Cr, Ni, and to its cylinder sleeve bore high-frequency quenching, inner bore honing Cylinder sleeve afterwards carries out vulcanization anti-attrition treatment again, and the Combined Processing layer that a kind of wear-resistant and anti-attrition is combined, hair are formed in cylinder sleeve bore The running-in period of motivation can shorten 1/2, more than 3 times of extension cylinder sleeve service life.
