Description

technical field

[0001] The invention relates to the field of faucet production, in particular to a faucet manufacturing process for swelling or stretching with water or oil. Background technique

[0002] At present, the main body of the traditional faucet is mainly made of precision casting or welded stainless steel. The manufacturing cost of the main body is high, the surface treatment process is complicated, and it cannot be directly thrown into a mirror surface. There are few styles and low output; the scrap rate is high and the product density is low. Contents of the invention

[0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a faucet manufacturing process that is expanded or stretched with water or oil.

[0004] The above object of the present invention is achieved through the following technical solutions: a faucet manufacturing process that expands or stretches with water or oil, is characterized in that it ...

Examples

Embodiment Construction

[0015] Below in conjunction with embodiment the present invention is further described in detail.

[0016] As shown in Figure 1, a faucet manufacturing process for swelling or stretching with water or oil is characterized in that it includes the following steps:

[0017] A faucet manufacturing process for swelling or stretching with water or oil, characterized in that it includes the following steps:

[0018] (1) Selection of pipe material: use 304 stainless steel pipe, 316 stainless steel pipe or copper pipe;

[0019] (2) Stretching prototype: use a hydraulic stretching machine, put the pipe into the stretching machine mold, stretch it for 18-22 seconds with a pressure of 220-270 tons, and stretch out the semi-finished product of the special-shaped tube. A 15cm-long special-shaped tube weighs 250 grams and requires 320 grams of stainless steel;

[0020] (3) Expansion molding: heat the stretched 1Scm long semi-finished product body with a weight of 250 grams and put it into ...
