Production process of single-outlet faucet body

Abstract

The invention relates to a production process of a single-outlet faucet body. The process comprises the following steps that a round copper bar is cut into a plurality of sections by a cutting machine; the plurality of sections of round copper bars are heated through fire spraying lamps, and the flame temperature of the fire spraying lamps is controlled to be 550-650 DEG C until the surfaces of the round copper bars are in dark red state; the general red copper rod is placed into a mold cavity of a forging machine for stamping and forming; after the forged pieces are completely cooled, the stamping forming pieces are placed in a trimming die, and redundant flash edges are cut off; the forged pieces are machined after trimming, heating and cooling is carried out, and the water outlet pipe of the faucet body is subjected to bending and deforming; and finally, polishing, detecting, packaging and warehousing are carried out. According to the production process of a single-outlet faucet body, the forged pieces are placed into a specially-made die to be extruded and formed through a forging machine, the production efficiency is greatly improved, the defects existing in the existing casting process are well solved, the strength is higher than the strength of a casting, the process is easy and convenient to implement, and the processing efficiency is high.

Description

Technical field [0001] The invention relates to the processing technology of a faucet valve body, in particular to a production process of a single-outlet faucet body. Background technique [0002] At present, single-outlet faucets have become more and more widely used. Single-outlet faucets mainly include single-outlet faucet body, valve core, and handle. The single-outlet faucet body is made by gravity casting. The products produced by this process include the following defect: [0003] 1. The mechanical properties of the main body of the single-outlet faucet are not as good as forgings, and many problems such as coarse structure, blisters, segregation, looseness, pores, slag inclusion, etc. may occur; [0004] 2. In the sand casting, single piece, small batch, workers are labor intensive and need to make additional sand cores; [0005] 3. The quality of castings is unstable, there are many procedures, and the influencing factors are complex, which easily cause many defects. Summa...

AI Technical Summary

Problems solved by technology

[0003] 1. The mechanical performance of the main body of the single-outlet faucet is not as good as that of the forging, and it is prone to various problems such as coarse structure, trachoma, segregation, looseness, pores, and slag inclusion;

[0004] 2. In sand casting, single piece and small batch, the labor intensity of workers is high and additional sand cores need to be made;

[0005] 3. The quality of castings is unstable, there are many processes, and the influencing factors are complex, which can easily cause many defects
