Manufacturing method of stainless steel wash basin drainer

Abstract

A manufacturing method of a stainless steel wash basin drainer comprises the steps as follows: blanking is performed through a conventional stainless steel tube or stainless steel plate; threads are turned on the outer wall of an upper stainless steel connecting pipe and the inner wall of a lower stainless steel connecting pipe respectively; the upper stainless steel connecting pipe can be screwed on the lower stainless steel connecting pipe through the threads; and a bounce cover is punched by a punch press, and polishing treatment and surface electroplating are performed, tubes are detected and packaged for storage. According to the manufacturing method of the stainless steel wash basin drainer, the stainless steel tube or stainless steel plate is formed through hydraulic forming, thread turning, argon arc welding and assembling, and phenomena of trachoma, bubbles and the like, which are caused by a conventional casting method, are effectively avoided; and the surface can be treated easily, the luminance duration and the service life of the stainless steel tube are longer than those of other materials, when the stainless steel wash basin drainer is mounted, a spanner and other tools are not needed, and the operation is convenient and rapid.

Description

technical field [0001] The invention belongs to the technical field of fluid pipeline manufacturing technology, and specifically relates to a manufacturing method of using stainless steel pipes and stainless steel plates to form face pans. Background technique [0002] The washbasin sewer device is used to remove domestic sewage. The existing washbasin sewer is usually made of copper or zinc alloy material through mold casting, because during the casting process of the mold, the temperature around it and the mold temperature inside the mold are uniform. It will affect the molding effect of the product, accompanied by trachoma, air bubbles, oxidation and other phenomena, which will affect the service life of the washbasin drain, especially for zinc alloy drains.

[0002] The washbasin sewer device is used to remove domestic sewage. The existing washbasin sewer is usually made of copper or zinc alloy material through mold casting, because during the casting process of the mold, the temperature around it and the mold temperature inside the mold are uniform. It will affect the molding effect of the product, accompanied by trachoma, air bubbles, oxidation and other phenomena, which will affect the service life of the washbasin drain, especially for zinc alloy drains. Although zinc alloy die casting and processing have many advantages, it is easy to form and easy The processing and hand feel are good, but the oxidation is fast. It is used in the bathroom with a lot of water and ammonia, and its service life is not long. Therefore, in recent years, people have focused on the development of stainless steel washbasins. The manufacturing process still uses molten The stainless steel is poured into the shell mold, the stainless steel is solidified and formed, and then polished and other surface treatments are carried out. The wax model of the basin water matches, and the shell mold can be obtained by dipping the slurry and dewaxing; 2. To make the washbasin water, inject molten stainless steel into the shell mold, and release the mold after the stainless steel is solidified, and the washbasin sewage blank can be obtained , and carry out surface treatment through various processes such as stamping shaping and polishing

The main disadvantages of the stainless steel washbasin are: ①. Because the stainless steel material is hard, it is formed by wax casting, and the casting melting point is high. It is difficult to control the temperature in the mold and the surrounding environment, and it is easy to produce trachoma and air bubbles, resulting in shortened service life of the finished product. ; ②, after water molding, its surface is hard and difficult to polish and electroplating, high processing precision requirements, many processes, high consumables, and high labor intensity for production
