Further specify accompanying drawing in conjunction with the embodiments, valve core structure of the present utility model as shown in Figure 1, this spool 1 has the spherical outer surface and of band groove 11 and crosses opening 12, according to using needs, spool 1 outer surface has straight groove or horizontal groove (Fig. 1 is horizontal groove), the turning cylinder of valve body is stretched into the engagement of spool drive valve core rotation and open or valve-off to transmit torsion.Method of the present utility model has the following steps:
A. the utility model adopts in type metal tube to make blank, guarantees the quality of raw material, and at first the metal tube with certain specification is cut into suitable section base 1;
B. use special-purpose punch die 2 towards groove to go out groove 11 at section base (workpiece) 1 outer surface middle part on punch press, groove can divide straight trough or translot according to user's requirement, and straight groove of punching out or horizontal groove adopt corresponding straight groove mould or translot mould;
C. will in packing forging die 3 into, fluted 11 workpiece 1 be pressed into spherical outer surface by forging press;
D. with the workpiece 1 of forging forming through finish turning to the predetermined dimension size;
E. finish turning to the surface of the work of preliminary dimension is carried out polishing and become spendable product.
Particular manufacturing craft of the present utility model is characterized in that being made up of punch die 2 and moulding forging die 3 towards groove, and embodiment is shown in Fig. 2 and Fig. 7 ratio.
Described punch die 2 towards groove is made up of mould bases 21, counterdie 22 and patrix 23, mould bases 21 is fixed in the bottom of punch press, counterdie 22 places on the arcuation groove piece 211 of mould bases 21, the described arcuation groove 211 of an embodiment of the present utility model is the branch body structure with mould bases 21, and nationality pin 213 interfixes.The arcuation of its arcuation groove matches with the counterdie of corresponding size 22.
