Embodiment Construction

[0016] 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.

[0017] The invention relates to a processing technology for a faucet valve stem. In order to facilitate cold heading processing, the material of the faucet valve stem is 304HC3 stainless steel, the valve stem body, the external spline of the connecting part, and the convex groove and plugging used for thread processing inside. The inner groove of the valve stem and the forks on both sides are formed by a one-time cold heading process; for the sake of processing accuracy, the inner thread of the connecting part is formed by tapping technology, and the outer groove of the valve stem body is formed by one-time turning. There are 2 deep grooves in the outer groove of the stem body, and the distance between the deep grooves is 3-4mm.

Abstract

The invention discloses a faucet valve rod machining process. According to the faucet valve rod machining process, a valve rod body, an external spline of a connecting part, a protruding groove formedin the connecting part and used for thread machining, an inner groove of a blocking part and shifting forks on the two sides of the blocking part are formed through an integral one-time cold headingprocess; and inner threads of the connecting part are formed through a tapping process, and an outer groove of the valve rod body is formed through one-time turning. The whole cold heading machining process is simple, the production efficiency is high, the finished product ratio is high, the machining precision is high, the production cost is low, and a produced valve rod is good in sealing performance and stability, light and convenient to operate and durable.

Description

technical field [0001] The invention relates to a processing technology for a faucet valve stem. Background technique [0002] The processing technology of the finished faucet valve stem blank on the market generally includes the steps of feeding and cutting, first shaping, positioning, stretching, extrusion, second extrusion, second stretching, second shaping, etc. The structure of the mold used is complicated, and the processing technology is also complicated, resulting in low production efficiency, low yield, low processing precision and high processing cost. Contents of the invention [0003] The purpose of the present invention is to provide a forming process for the faucet valve stem with simple processing procedures, high production efficiency, high yield, high processing precision and low production cost. The valve stem produced has good sealing performance and stability, and is easy to operate and durable. [0004] In order to achieve the above object, the prese...
