Problems solved by technology
[0002] At present, wall-mounted faucets for hot and cold water are widely used in bathing places such as bathtubs and showers. S-shaped joints are used as the main connection accessories of faucets. Under the environment, bearing the weight of the entire faucet, after a long period of thermal expansion and contraction, corrosion and material oxidation, the service life of the S-shaped joint will be shortened, thereby affecting the life of the overall faucet
[0003] In the prior art, S-shaped joints are usually produced by melting and casting process. The casting method is complicated and cumbersome, consumes a lot of energy, and is limited to defects in process technology. The finished S-shaped joints produced are prone to defects such as protrusions and cracks, and the product strength and durability Corrosion is also poor, which reduces the performance and yield of the product, resulting in the quality of the S-shaped joint cannot be guaranteed
In addition, the processing technology of the existing S-shaped joint casting method is difficult, resulting in relatively high production costs

Embodiment Construction
[0022] see Figure 1 to Figure 4 As shown, a kind of manufacturing process method of S-shaped joint provided by the present invention, this process method comprises the following steps:
[0023] Step 1, preparing a solid bar stock 1 made of metal;
[0024] Step 2, heat-treating the solid bar 1;
[0025] Step 3, sending the heated solid bar 1 into the equipment for cold heading or hot forging processing to form a T-shaped hollow tube 2;
[0026] Step 4, stamping the T-shaped hollow tube 2 to form an S-shaped joint blank 3;
[0027] Step 5: Machining or rolling threads at both ends of the S-shaped joint blank 3 to make an S-shaped joint finished product 4. The diameter of the front end of the prepared S-shaped joint is larger than that of the rear end, the front end is the water outlet port, and the rear end is the inlet water connection.
[0028] The heating temperature in the above step 2 is 500°C-1000°C. By heating to a specific temperature, it can ensure that the solid b...

The invention discloses a manufacturing technique of an S-shaped connector. The manufacturing technique includes the steps of 1, preparing a solid rod of metal material; 2, heating the solid rod; 3, feeding the heated solid rod into a device for cold heading or hot forging, thus forming a T-shaped hollow tube; 4, stamping the T-shaped hollow tube to form an S-shaped connector blank. The solid rod is formed by cold heading or hot forging; the solid rod is highly plastic during forming, special sectional shapes can be formed economically, a product has high strength and mechanical performance, service life of the product is prolonged, yield is increased, utilization rate of materials is up to 80% to 90%, the steps are simplified, production cost is lowered, product quality is improved, and economic benefit is improved.
Description
technical field [0001] The invention relates to a production technology of a faucet connector, in particular to a method for manufacturing an S-shaped joint suitable for a wall-mounted faucet. Background technique [0002] At present, wall-mounted faucets for hot and cold water are widely used in bathing places such as bathtubs and showers. S-shaped joints are used as the main connection accessories of faucets. Under the weight of the entire faucet, after a long period of thermal expansion and contraction, corrosion and material oxidation, the service life of the S-shaped joint will be shortened, thereby affecting the life of the overall faucet.
