Process for generating faucet quick-opening valve body

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0027] see Figure 1 to Figure 6 , a production process of a faucet quick-opening valve body, comprising the following steps:

[0028] S1. Blanking: straighten and heat 304 stainless steel, and cut it into a set length;

[0029] S2, the first shaping: the first shaping process is performed on the cut blank to make the blank appearance neat and free of burrs and burrs;

[0030] S3. Positioning: After the shaped blank is turned over, an annular hole is punched at one end of the blank for positioning;

[0031] S4. The first stretch: the positioned blank is stretched according to the product size requirements, and the other end of the blank is arranged into a hexagonal shape;

[0032] S5. Positive extrusion: After turning the stretched blank, the hexagonal head of the blank is extruded according to the size requirements, and at the same time, the hexagonal upper part of the blank is extruded to form a bulge, and the annular bulge is formed. The length meets the requirements of the product size;

[0033] S6, punching: punching the extruded blank, punching out the two positioning grooves of the ceramic static piece;

[0034] S7, punching the positioning block: continue to punch the blank with the punched positioning groove, process and punch out the symmetrical bump for the valve stem switch water outlet;

[0035] S8. Punching through holes: continue punching and processing the blanks of the punched positioning bumps, and punch out through holes of the required size of the valve stem;

[0036] S9. Reshaping: Reshaping the blank after punching through the hole, and reshaping the corners of the blank. After finishing, the finished blank that meets the blank size of the valve core body is obtained.

[0037] Further, the positioning is performed by clamping in a cold heading die and extruding with a punch.

[0038] Further, in the step S1, the heating temperature is greater than 500 degrees.

[0039] The outer surface of the previous blank has two sections, namely hexagonal and cylindrical with the same size from top to bottom, because the two-section cold heading technology is simple, but it brings great difficulties to the subsequent machining;

[0040] If the two water outlets of the valve body are milled first, because the wall of the valve body is too thick, it will not only consume tools but also time-consuming when milling the grooves. Machining and deburring. Increased processing costs. The waste of cold pier material is serious.

[0041] The above-mentioned embodiments only represent the embodiments of the present invention, and the descriptions thereof are specific and detailed, but should not be construed as limiting the scope of the patent of the present invention. It should be pointed out that for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
