Example Embodiment
[0028] Example 1
[0029] (1) Choose WASPALOY rod-shaped raw materials, carry out blanking, and then upset the raw materials to make the length and thickness suitable;
[0030] (2) Punching the upsetting raw material to make the center open;
[0031] (3) Carry out the horse frame reaming of the punched raw material to make the hole size suitable, the raw material volume is reasonably distributed, and the rectangular cross-section ring blank is obtained;
[0032] (4) Use a mold with a trapezoidal cross-section to drive in from the lower part of the ring blank to make the side wall of the ring blank tilt outward and become a bell shape;
[0033] (5) Use the method of tire mold blank to process the ring blank, set molds on the inner and outer sides of the ring blank, and then roll, make the shape of the ring blank close to the shape of the final forging, so as to facilitate the smooth progress of subsequent rolling;
[0034] (6) Use as attached Figure 5 The rolling mill shown with a speci...
