Abstract

The invention relates to a faucet and a manufacturing process thereof, which are used for solving a series of problems such as high faucet cost, high possibility of rusting of cast iron and non-durable plastic parts in the prior art. The faucet comprises a main body made of cast aluminium alloy; and the cast aluminium alloy comprises the following elements in percentage by mass: 0.8 to 1.8 percent of iron, 9.7 to 10.7 percent of silicon, 2 to 3 percent of copper, 0.7 to 1.7 percent of manganese, 0.1 to 1 percent of magnesium, 0.1 to 0.3 percent of titanium and aluminium in balancing amount. The main body is formed by casting the aluminium alloy, so that the faucet has the advantages of easiness for processing, low cost, corrosion resistance, no rust, strong recoverability and the like; and the element ratio of the aluminium alloy can play the optimal mechanical properties such as yield strength and the like.

Description

Water tap and manufacturing process thereof

Technical field

The present invention relates to a kind of water tap.

Background technology

The tap main body material gold that appears at present on the market is goods such as copper alloy, cast iron, plastics, and its shortcoming mainly is presented as: copper alloy cost height, cast iron easily get rusty, and plastic component is not durable etc.

Summary of the invention

The invention is intended to provide a kind of water tap, to solve water tap cost height of the prior art, cast iron easily gets rusty, plastic component a series of problems that are not durable.

Water tap in this programme, it is characterized in that: comprise the main body that aluminium diecast alloy is made, each element quality proportioning is in the described aluminium diecast alloy: 0.8% ~ 1.8% iron, 9.7% ~ 10.7% silicon, 2% ~ 3% copper, 0.7 ~ 1.7% manganese, 0.1% ~ 1% magnesium, 0.1% ~ 0.3% titanium and the aluminium of surplus.

Material of main part adopts the aluminium alloy compression casting moulding, has the processing of being easy to, and cost is lower, and is corrosion-resistant, non-corrosive, and advantage such as recovery property is strong, described aluminium alloy element proportioning can be brought into play the mechanical properties such as yield strength of the best.

Following table can illustrate the various advantages of aluminium diecast alloy main body:

?	The copper alloy main body	Cast iron body	Plastic body	The aluminium diecast alloy main body
					Weight	Heavier	Slightly heavy	Lighter	Moderate
Processing characteristics	Be easy to processing	Be difficult for processing	Be easy to processing	Be easy to processing
					Cost	High	Moderate	Low	Moderate
Preservative property	Moderate	Low	Low	High
					Recovery property	High	Low	Low	High
Durability	Durable	Be not durable	Be not durable	Durable
					Aesthetic measure	Moderate	Bad	Bad	Good

Further, each element quality proportioning is in the described aluminium diecast alloy: 1.3% iron, 10.2% silicon, 2.5% copper, 1.2% manganese, 0.5% magnesium, 0.2% titanium and the aluminium of surplus.

The present invention also provides the manufacturing process of above-mentioned water tap, to solve the low problem of water tap intensity of the prior art.

The manufacturing process of the water tap in this programme, it is characterized in that comprising following step in sequence: aluminium alloy preparation, aluminium alloy compression casting are tap main body, tap main body mechanical workout, tap main body surface treatment, tap main body pressure testing and detection, tap main body assembling, and each element quality proportioning is in the described aluminium alloy: 1.3% iron, 10.2% silicon, 2.5% copper, 1.2% manganese, 0.5% magnesium, 0.2% titanium and the aluminium of surplus.

It is good that the water tap that the above-mentioned technology of process is made has density, the intensity advantages of higher.

Embodiment

Water tap among the embodiment one includes main part, and it is made for aluminium diecast alloy.

Above-mentioned water tap is made by following steps: the allotment aluminium alloy solution, wherein each element mass percent is: 0.8% iron, 9.7% silicon, 2% copper, 0.7 manganese, 0.1% magnesium, 0.1% titanium and the aluminium of surplus, the aluminium of surplus is about 86.6%, and other has the impurity of trace.

The main body mould is installed on the high speed pressure die-casting machine, configure the die casting parameter, use the fixedly casting pressure of 750Kg/c ㎡, keep the mould temperature to be higher than 250 ℃, the molten aluminium alloy temperature is 720 ℃, and liquation injects mould, this foundry goods weave construction densification through high pressure, have higher intensity, again this foundry goods is taken out to carry out mechanical workout.Remaining steps in sequence is to the body surfaces processing, to main body pressure testing and detection, main body and other accessories is assembled together.

In another embodiment, only be that with embodiment one difference each element mass percent is in the aluminium alloy solution: 1.8% iron, 10.7% silicon, 3% copper, 1.7% manganese, 1% magnesium, 0.3% titanium and the aluminium of surplus.

In another embodiment, only be that with embodiment one difference each element mass percent is in the aluminium alloy solution: 1.3% iron, 10.2% silicon, 2.5% copper, 1.2% manganese, 0.5% magnesium, 0.2% titanium and the aluminium of surplus.

Above-described only is embodiments of the invention, and general knowledge such as known concrete structure and characteristic are not done too much description at this in the scheme.Should be understood that; for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not influence effect of the invention process and practical applicability.
