Method for producing stainless steel tap

Abstract

The invention provides a method for manufacturing a stainless steel water faucet for solving the process problem that articles with complex structures and thin walls such as a die cavity and the like are hard to be made from stainless steel at domestic, which comprises the following steps: using a finish cast die to manufacture a wax mould same as the blank of a water faucet valve body; after dipping slurry and adhering to sand on the wax mould, forming a sand mould in a through dewaxing in a dewaxing kettle; casting the stainless steel on the sand mould; and when the stainless steel is solidified, desanding the stainless steel through vibration to manufacture the blank of the water faucet valve body, wherein the outer wall of a water passage formed in the blank of the valve body is reserved with an opening; and after the blank of the water faucet valve body is formed, welding a cover plate to form the valve body which is then polished and assembled. The method for manufacturing the stainless steel water faucet has the advantages of simple process, high finished product ratio, economization of stainless steel materials and low cost, solves the process problem that the articles with the complex structures and the thin walls such as the die cavity and the like are hard to be made from stainless steel at domestic, and prevents the problem that the water faucet made from the stainless steel is easy to generate perforation and water leakage so that the finished product ratio is low because of the complex structure and the thin wall of the die cavity of the water faucet.

Description

technical field [0001] The invention relates to the field of faucet manufacturing technology, in particular to a method for making a stainless steel faucet by pouring stainless steel into a sand mold formed after a precision casting mold-wax mold-sand mold process. Background technique [0002] Faucets are not only widely used in daily life, but also in other fields such as laboratories, factory crafts, etc., and with the development of the economy, faucets used in daily life are increasingly required to be cheap, high-quality, Beautiful, so the faucet manufacturing process is also constantly using new materials and new technology. The faucets currently used are generally made of brass, stainless steel and other materials. Among them, brass is easy to stretch and easy to make with common processes, so it is widely used in the faucet manufacturing process. Because pure copper is soft and in order to reduce costs, When making a faucet with brass, zinc and a small amount of le...

Problems solved by technology

[0003] In order to solve the technological problem of using stainless steel to make mold cavities with complex structures and thin walls in China, the present invention provides a method for manufacturing stainless steel faucets. Due to the complexity of the mold cavity of stainless steel faucets, the method of manufacturing stainless steel faucets is firstly processed through fine-tuning. Casting mold-wax mold-sand mold-casting stainless steel to make the outer wall of the water passage, leaving a valve body blank with several openings, then welding the cover plate on the opening and polishing and assembling. The process is simple, the yield is high, and stainless steel is saved. Material, cost reduction
