The technology is that the Al alloy raw material matched in terms of the above mentioned proportion is smelted in a thermal insulation furnace, refined, gas cleaned-up and modificated with dust refinery agent and the solution temperature is monitored by a dogmatic thermometer via a thermal coupler, then an alloy iron cast cylindrical jacket is put on the position of its mold to pour the solution onto the mold cavity to be casted with low pressure casting so as to integrate the jacket with the solution finally it is finished by the process center.
Description
One, technical field
The present invention relates to Aluminum Alloy Cylinder Barrel and manufacturing process thereof that a kind of petrol engine is used.
Two, background technology
Existing petrol engine Aluminum Alloy Cylinder Barrel adopts aluminium alloy ADC12 (trade mark) material to carry out high-pressure casting and forms.This manufacturing process used device cost height, the cylinder body interior tissue of output is not fine and close, and pore is more, poor air-tightness, foundry goods need all carry out " infiltration is handled " subsequent handling, promptly need add leak stopping glue pore is stopped up, and wastes bigger.And this foundry goods can not be heat-treated, the as cast condition bad mechanical property, and generally at 150-180MPa, hardness is low, machinability, wear no resistance, the product processing difficulties, roughness is poor, thereby has influenced the serviceability of engine.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and a kind of tensile strength height, wear resistance is good, hardness is high Aluminum Alloy Cylinder Barrel and manufacturing process thereof are provided.
Purpose of the present invention realizes by following technical solution: a kind of wear-resistant aluminum alloy cylinder body, the Chemical Composition of described cylinder body is calculated by weight, and it constitutes: 7.6-8.3% silicon, 2.5-3.5% copper, 0.3-0.5% magnesium, 0.2-0.4% manganese, surplus are aluminium.The Chemical Composition of described cylinder body is calculated by weight, and its foreign matter content is not more than: 0.5% iron, 0.3% zinc, 0.2% lead, 0.2% chromium, 0.1% tin, 0.1% nickel, 0.1% titanium.
The manufacturing process of above-mentioned wear-resistant aluminum alloy cylinder body is: will prepare complete raw material of aluminum alloy according to the above ratio and directly carry out melting in holding furnace, use the injection refining agent that aluminium alloy solution is directly carried out refining degasification, the rotten processing by the refining getter again, and adopt digital display temperature meter directly the temperature of aluminium alloy solution to be monitored simultaneously by thermopair, the quality of aluminium alloy solution is guaranteed; Then the cast alloy iron cylinder sleeve is put on the cylinder body mould location, again this alloy liquid is poured in the cylinder body mold cavity, adopt the air injection machine of full-automatic servo-control system directly to carry out low-pressure casting, cast alloy iron cylinder sleeve and alloy liquid be connected as a single entity, after Cutter Body Processing with Machining Center form.
Above-mentioned manufacturing process can also for: the cylinder body work in-process that above-mentioned low-pressure casting is made are put into quenching furnance and are carried out solution treatment, after aging oven 3-6 hour, take out then, after Cutter Body Processing with Machining Center form.
After adopting the present invention, because the inside Chemical Composition of this cylinder body and variation, the improvement of manufacturing process make its dense internal organization, resistance to air loss is good, and 80% foundry goods no longer need carry out " infiltration is handled ", and its casting formability, processibility are all good, wear resistance is good, and cost is lower; Its tensile strength sigma
bCan be up to 280-310MPa, unit elongation δ
5Reach 2-3%, Brinell hardness reaches 110-130HBS.
Four, embodiment
The aluminum alloy materials of wear-resistant aluminum alloy cylinder body of the present invention (trade mark is AC4B-RM) Chemical Composition is calculated by weight, and it constitutes: 7.6-8.3% silicon (Si), 2.5-3.5% copper (Cu), 0.3-0.5% magnesium (Mg), 0.2-0.4% manganese (Mn), surplus are aluminium (Al).
The Chemical Composition of described cylinder body is calculated by weight, and its foreign matter content is not more than: 0.5% iron (Fe), 0.3% zinc (Zn), 0.2% lead (Pb), 0.2% chromium (Cr), 0.1% tin (Sn), 0.1% nickel (Ni), 0.1% titanium (Ti).
The manufacturing process of above-mentioned wear-resistant aluminum alloy cylinder body is: will prepare complete raw material of aluminum alloy according to the above ratio and directly carry out melting in holding furnace, use injection refining agent (is good with imported product) that aluminium alloy solution is directly carried out refining degasification, the rotten processing by the refining getter again, and adopt digital display temperature meter (1.5 grades) directly the temperature of aluminium alloy solution to be monitored simultaneously by thermopair, the quality of aluminium alloy solution is guaranteed; Then cast alloy iron cylinder sleeve (wear-resisting) is put on the cylinder body mould location, again this alloy liquid is poured in the cylinder body mold cavity, adopt the air injection machine (Japan Isuzu Motors of full-automatic servo-control system, 0.15--0.45MPa about) directly carry out low-pressure casting, cast alloy iron cylinder sleeve (wear-resisting) and alloy liquid are connected as a single entity, after Cutter Body Processing with Machining Center form.Thereby melting, castingprocesses are effectively controlled on production unit and technology.
For tensile strength, unit elongation, hardness and the thermotolerance that significantly improves this cylinder body, improve its machinability, the cylinder body work in-process that above-mentioned low-pressure casting can also be made are put into quenching furnance and are carried out solution treatment, after aging oven 3-6 hour, take out then, after Cutter Body Processing with Machining Center form.That is to say that this cylinder body die casting can make the compound Mg that is formed by raw material of aluminum alloy by thermal treatment
2Si, Al
3Mg
2, CuAl
2Strengthened by thermal treatment, thus the mechanical property of raising Aluminum Alloy Cylinder Barrel.The mechanical property situation of this Aluminum Alloy Cylinder Barrel under different states is as shown in table 1:
