Background technique
The water nozzle of tradition water tap adopts brass low-pressure die casting or gravity casting to form conventionally, and the water nozzle cavity of the part of paddling is wherein generally to be formed by core, because intensity and the rigidity of core are inadequate, so be difficult to adopt die casting or extrusion casint to be produced.Adopt the shortcoming of brass casting water nozzle to be: 1, copper metallic material price is high, causes water nozzle cost high; 2, the heavy metal element such as general leaded in brass, brass water nozzle easily causes environmental pollution in the bright and clean process of machining.
At present, water nozzle also has the iron and steel of employing or stainless steel material to make.Adopt the deficiency of the water nozzle of ferrous materials making to be easily to produce corrosion, affect working life and aesthetics.Although the water nozzle rust resistance that adopts stainless steel material to make is higher, the high difficult processing of the hardness of stainless steel material, processing cost is high.
Therefore, the water nozzle that adopts aluminum alloy to make progressively starts to come into one's own, but owing to adopting the aluminium alloy castings of low-pressure die casting or gravity casting easily to produce the defects such as shrinkage cavity, pore, make the whole production up-to-standard rate of low-pressure die casting or gravity casting aluminum alloy water nozzle that adopts not high.
Summary of the invention
Technical problem solved by the invention is the deficiency for above-mentioned existence, and provide, a kind of production up-to-standard rate is high, cost of production is lower, and in production process, can not cause the manufacture method of the aluminum alloy water nozzle of environmental pollution.
The technical solution adopted in the present invention is: a kind of manufacture method of aluminum alloy water nozzle, is characterized in that concrete steps are as follows:
1. first by aluminium alloy stock, by gravity casting or low-pressure casting method, cast out the aluminium alloy prefabricated component containing core, core is completely enclosed within the inside of aluminium alloy prefabricated component, forms a closed core cavity;
2. by aluminium alloy stock, by semisolid extrusion casting method, cast out again the aluminum alloy water nozzle main body wrapping in aluminium alloy prefabricated component periphery;
3. then by machining mode, the water intake of aluminum alloy water nozzle, water outlet are processed, then will after the core fragmentation of aluminium alloy prefabricated component inside, take out, form the cavity of paddling of aluminum alloy water nozzle inside;
4. again through following process, make aluminum alloy water nozzle.
Described step 1. in the component of cast aluminium alloy prefabricated component aluminium alloy stock used and the quality percentage composition of each component be: 3%～7%Si, 0.1%～0.7%Mg, 0.1%～0.3%Ti, all the other are Al; Described step 2. in the component of cast aluminium alloy water nozzle main body aluminium alloy stock used and the quality percentage composition of each component be: 5%～9%Si, 0.3%～0.9%Mg, 0.1%～0.3%Ti, 1%～4%Cu, all the other are Al; The described step 2. temperature of middle semisolid extrusion casint is controlled at 650～700 ℃, and pressure is controlled at 48～80MPa.
The invention has the beneficial effects as follows: 1, the present invention adopts aluminium alloy stock to manufacture water nozzle, compares with adopting brass casting water nozzle, can reduce production costs, and manufacture process can not cause environmental pollution; 2, the present invention first casts out the aluminium alloy prefabricated component containing core by gravity casting or low-pressure casting method, by semisolid extrusion casting method, cast out the aluminum alloy water nozzle main body wrapping in aluminium alloy prefabricated component periphery again, overcome and adopted the aluminium alloy castings of low-pressure die casting or gravity casting easily to produce the defects such as shrinkage cavity, pore completely, thus quality of product and the production up-to-standard rate of raising aluminum alloy water nozzle; 3, in the present invention, aluminum alloy water nozzle main body adopts rational aluminium alloy stock formula, and form by the casting of semisolid extrusion casting method, make the appearance quality of aluminum alloy water nozzle main body good, dense internal organization and mechanical property high, wear resistance, anti-leakage performance are good, avoid producing the defects such as shrinkage cavity, pore, thereby can improve quality of product and the production up-to-standard rate of aluminum alloy water nozzle; 4, the present invention adopts core is completely enclosed within to aluminium alloy prefabricated component inside, when by semisolid extrusion casting method cast aluminium alloy water nozzle main body, can not be subject to intensity and the inadequate impact of rigidity of core, be conducive to ensure the quality of aluminum alloy water nozzle main body, thereby improve the production up-to-standard rate of aluminum alloy water nozzle.
