The specific embodiment
To combine accompanying drawing and specific embodiment to specify the present invention below, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as to qualification of the present invention.
Embodiment 1:
Referring to shown in Figure 1, this cylinder sleeve pouring procedure mainly comprises following flow process:
Step 101: adopt the first raw material spun casting overcoat.
The pulpous state raw material of preprepared electro-smelting is put into the mould of rotation; Utilize the method for centrifugal forming tubulose or hollow tubular article, raw material is wherein rotated, at this moment around single shaft at a high speed; The material of putting into is promptly forced by centrifugal force and is distributed in the nearly wall of mould; In rotation, slaking can take place through aspects such as heating in the raw material of putting into, and forms the annulus stratiform of casting.
In present embodiment technology, the raw material that the casting overcoat adopts can but be not limited to steel No. 45, experiment showed, and adopt No. 45 steel can guarantee that its overcoat has high-intensity rigidity.
Step 102: adopt the composite material of first raw material and second raw material, at the inwall spun casting transition zone of steel sleeve.
After its external sleeve casting finishes; Insert in the mould of rotation at the raw material that is smelted into pulpous state, the material that in this step, uses is the composite material of overcoat, interior cover, adopts the spun casting shown in step 101; Make these composite materials cast in the inwall of overcoat, form transition zone.
In addition, this transition zone adopts overcoat, interior cover composite material to process, and can make full use of useless cover, with the material of " smear metal " waste material in process as transition zone; Accomplish the very recycling of waste material, the material practical efficiency reaches more than 95%, has greatly reduced production cost; Shorten the processing technology time; Yield rate is high, has improved the quality of cylinder sleeve, and percent defective is dropped to minimum point.
In present embodiment technology, the raw material that the casting overcoat adopts can but be not limited to high ferrochrome, experiment showed, and adopt high ferrochrome can guarantee that cylinder sleeve has highly corrosion resistant, meet the present embodiment parts be applied to consumable accessory technical conditions requirements such as slush pump.
Wherein high ferrochrome can but be not limited to constitute by following component:
C：3.0-3.5；Si：0.5-0.8；
Mn：0.6-1.0；S：＜0.05；
P：＜0.05；Cr：18-20。
It is following to experiment showed, that the bimetallic material that adopts No. 45 steel and above component carries out the mechanical performance of the cylinder sleeve that casting successively obtains:
Impact flexibility: 5-8J/C m
2, (test result under the as cast condition);
Bending strength: 400-600N/m
2(test result under the as cast condition);
Hardness: HRC:50-56; (as cast condition test result);
38-40: (softening back test result);
62-68: (quenching test result).
Step 103: adopt the inwall of second raw material, cover in the spun casting at transition zone.
After transition zone casting finished, the material of cover in the mould of rotation, injecting (in the present embodiment can but be not limited to high ferrochrome) adopted the spun casting shown in step 101, makes these composite materials cast in the inwall of transition zone, overlaps in forming.
Step 104: modified to said cylinder sleeve integrally annealed.
Cylinder sleeve integral body to the back of casting is made up of interior cover, transition zone, overcoat is annealed modified: change material-structure, improve intensity.Concrete annealing process can but be not limited to adopt existing annealing process.
Step 105: cylinder sleeve integral body is carried out Quenching Treatment.
Cylinder sleeve integral body to annealing modified is carried out Quenching Treatment; Cover hardness and intensity in improving: steel part is heated to austenitizing temperature and keeps certain hour; Then to cool off greater than critical cooling rate; To obtain non-diffusion-type transition tissue, like the Technology for Heating Processing of martensite, bainite and austenite etc.
Therefore owing to adopt two kinds of materials without material successively to cast in the present embodiment, overcoat, interior cover are linked to be together through the transition zone casting, have solved the problem that overcoat is press-offed easily in the cylinder sleeve,
And between two kinds of material casting, adopt the centrifugally cast mode of composite material; Constitute transition zone, this transition zone is the mixing of overcoat, interior cover material, so itself and interior cover, overcoat have compatibility preferably; Can fine and interior cover, overcoat bonds together, and guarantees the compatibility of overcoat, interior cover.
In addition, can also be after step 104 in present embodiment technology, comprise before the step 105
Step 201: the interior circle of cover in the cylindrical of car overcoat, car.
Wherein, can adopt first roughing, the accurately machined mode in back at the interior bowlder of car overcoat.
With respect to carrying out finished product machine tool processing after the step 105, increase this step in step 104, between 105 and can obtain performance, product that profile is better.
Embodiment 2
Therefore the cylinder sleeve that adopts said method to obtain is made up of jacket layer, transition zone, interior jacket layer, and structure wherein is following:
Transition zone casts in the inwall of jacket layer, and interior jacket layer casts in the inwall of transition zone.Wherein, the material of jacket layer in the material of jacket layer is different from, the material of transition zone is the mixing of cylinder sleeve layer material and said interior jacket material.
In the present embodiment, the raw material that the casting overcoat adopts can but be not limited to steel No. 45, experiment showed, and adopt No. 45 steel can guarantee that its overcoat has high-intensity rigidity.
In the present embodiment, the raw material that the casting overcoat adopts can but be not limited to high ferrochrome, experiment showed, and adopt high ferrochrome can guarantee that cylinder sleeve has highly corrosion resistant, meet the present embodiment parts be applied to consumable accessory technical conditions requirements such as slush pump.
Wherein high ferrochrome can but be not limited to constitute by following component:
C：3.0-3.5；Si：0.5-0.8；
Mn：0.6-1.0；S：＜0.05；
P：＜0.05；Cr：18-20。
It is following to experiment showed, that the bimetallic material that adopts No. 45 steel and above component carries out the mechanical performance of the cylinder sleeve that casting successively obtains:
Impact flexibility: 5-8J/C m
2, (test result under the as cast condition);
Bending strength: 400-600N/m
2(test result under the as cast condition);
Hardness: HRC:50-56; (as cast condition test result);
38-40: (softening back test result);
62-68: (quenching test result).
Therefore, since the overcoat that forms without material casting in the present embodiment, interior cover the two be linked to be together through the transition zone casting, solved the problem that overcoat is press-offed easily in the cylinder sleeve,
And between two kinds of material casting, adopt the centrifugally cast mode of composite material; Constitute transition zone, this transition zone is the mixing of overcoat, interior cover material, so itself and interior cover, overcoat have compatibility preferably; Can fine and interior cover, overcoat bonds together, and guarantees the compatibility of overcoat, interior cover.
More than the technical scheme that the embodiment of the invention provided has been carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the embodiment of the invention are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
