Problems solved by technology
[0002] Stainless steel faucet valve bodies are formed by cold processing, such as cold rolling or cold heading, etc. These stainless steel cold processing technologies have disadvantages such as complex processing procedures, low efficiency, easy cracking of the valve body during cold processing and difficult subsequent machining due to work hardening; The two rectangular openings on the surface of the spool shell are generally formed by wire cutting, laser processing, and milling. These processing methods have defects such as low processing efficiency, unstable product quality, low dimensional accuracy, and high cost; the spool shell The thread on the surface is formed by cutting, and its processing efficiency and processing accuracy are low

Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples.
[0019] The invention relates to a processing technology for a valve core shell of a faucet. In order to facilitate processing, the material of the valve core shell is 304B stainless steel, and the valve core shell and the opening, positioning groove, and paddle limit projection on the valve core shell The hex nut and the hexagonal nut are formed by integral hot heading; for processing efficiency and precision, the thread of the spool shell is formed by rolling technology, and the groove and arc-shaped groove of the spool shell are formed by turning.
[0020] Processing technology of the present invention specifically comprises the following steps:
[0021] (1) Cutting: Heat the 304B stainless steel rod with a diameter of 20mm to 500°C for straightening, and cut it into a set l...
