Problems solved by technology

[0003] However, the faucets in the prior art are generally formed by chrome-plated copper-steel composite structure. Because the copper is resistant to neutral water corrosion but not wear-resistant, and the galvanic battery reaction is prone to occur between copper and steel, there is no water faucet for domestic use. However, when used in medium and heavy industrial water control equipment, problems such as tube explosion, deformation, and blockage are prone to occur.

Embodiment 1

[0029] A high-wear-resistant flow-guiding faucet main body, which consists of a faucet main body 1 with a conical forging streamline concentrating toward the inner hole obtained through square-to-circle hot extrusion and swaging, and a faucet main body 1 that is arranged in the inner hole and shrinks with the faucet inner hole A diversion ring 3 with an acute-angle contour line at the mouth end, and a faucet valve 2 are also provided in the middle of the faucet main body 1 .

[0030] A method for manufacturing a high wear-resistant diversion nozzle body, comprising the following steps:

[0031] 1) Pre-preparation

[0032] ①Choose aluminum bronze copper billet as raw material;

[0033] ② Select forging equipment equipped with hydraulic generating device, rotary push device and air cooling device; select vacuum resistance furnace as initial forging heating equipment;

[0034] ③ Use four forged hammerheads 7 and matching hydraulic output device 8 as final forging and clamping t...

Embodiment 2

[0048] The whole is the same as Example 1, the difference is:

[0049] 2) forging

[0050]②The forging hammer head 7 linked with the rotary push device is pushed by the hydraulic generating device, and the copper billet is extruded into a forging billet with a nearly square cross section at a feed rate of about 5% for each deformation and a final deformation ratio of 45%;

[0051] ③Propel the forged billet with a nearly square cross-section at a speed of 0.25mm / s into the inner hole of the main body 4 of the ceramic tooling along the rotation axis on the basis of the joint rotation of the rotary push device and the forging hammer head 7;

[0052] ④ Install an air-cooling device at the outlet of the inner hole of the main body 4 of the ceramic tooling, and blow out nitrogen at a pressure of 3 bar for cooling;

[0053] ⑥Cool the forged copper billets within 10 minutes after forging at -75°C for 1.5 hours of ice-cooling treatment; then use 300°C for a time of (22d) min / mm based ...

Abstract

The invention relates to a high-wear-resisting flow guide type water nozzle body and a manufacturing method thereof. A water nozzle comprises the water nozzle body and a flow guide ring. The water nozzle body is obtained through square-to-circle hot extrusion rotary forging, and is inclined towards a forging flow line in an inner hole in a concentrated manner, the flow guide ring is arranged in the inner hole, and an acute angle is formed between the water nozzle inner hole and the flow guide ring in a manner of facing the shrinkage opening end contour line. The manufacturing method comprises the steps of precipitation-hardening stainless steel square-to-round hot extrusion rotary forging forming, stabilizing treatment, flow guide structure welding and stabilizing treatment, machining and conventional refining and the like. The strength is high, self wear resistance is achieved, the water nozzle body can be suitable for irregular high-pressure pulse muddy water flushing, and the flow guide function is achieved.

Description

technical field [0001] The invention relates to the field of water control equipment, in particular to a main body of a high wear-resistant diversion type faucet and a manufacturing method thereof. Background technique [0002] The faucet is a device for opening and closing the water medium and controlling the outlet water flow and water temperature. It is used to control the size of the water flow switch and has the effect of saving water. The replacement speed of faucet is very fast, from old-fashioned cast iron technology to electroplating knob type, and to stainless steel single temperature and single control faucet, stainless steel dual temperature and double control faucet, semi-automatic faucet, etc. [0003] However, the faucets in the prior art are generally formed by chrome-plated copper-steel composite structure. Because the copper is resistant to neutral water corrosion but not wear-resistant, and the galvanic battery reaction is prone to occur between copper and...
