Description
Technical field
The present invention relates to tap manufacturing technology field, be specifically related to a kind of manufacturer of aluminium alloy water nozzleMethod.
Background technology
The water nozzle of tradition tap adopts brass low pressure casting or gravitational casting to form conventionally, relating to whereinThe water nozzle cavity of water section is generally to be formed by core, because intensity and the rigidity of core are inadequate, so difficultProduce to adopt die casting or extrusion casint. Adopt the shortcoming of brass casting water nozzle to be: 1, copper metal materialMaterial price is high, causes water nozzle cost high; 2, the heavy metal element such as general leaded in brass, brass water nozzleIn the bright and clean process of machined, easily cause environmental pollution.
At present, water nozzle also has the iron and steel of employing or stainless steel material to make. The water nozzle that adopts ferrous materials to makeWeak point be easily to produce corrosion, affect service life and aesthetics. The stainless steel material system of employingAlthough the water nozzle rust resistance of doing is higher, high being difficult for of the hardness of stainless steel material processes, and processing cost is high.
Therefore, the water nozzle that adopts aluminium alloy to make progressively starts to come into one's own, but owing to adopting low pressure castingOr the aluminium alloy castings of gravitational casting easily produces the defect such as shrinkage cavity, pore, make entirety adopt low die castingMake or the production qualification rate of gravitational casting aluminium alloy water nozzle not high.
Summary of the invention
Technical problem solved by the invention is the deficiency for above-mentioned existence, and provides a kind of production qualifiedRate is high, production cost is lower, and in production process, can not cause the manufacture of the aluminium alloy water nozzle of environmental pollutionMethod.
