Then, the bolt 6 is passed through the socket 5 and tightened, so that the auxiliary ring 4 is fixed on the outside of the annular edge 2. A pre-connection mechanism is installed at the bottom of the inner platform 7. The auxiliary ring 4 has an upward force to support the final forming process during the downward movement of the spinning to prevent the occurrence of long and short sides. Through the action of the auxiliary ring 4, the occurrence of long and short sides is eliminated during the downward spinning process. By adding the auxiliary ring 4, the occurrence of long and short sides is solved, and a basis is provided for reducing the wear of the cutting tools in the subsequent machining and improving the machining efficiency, thereby solving the problems encountered in the actual production of spinning.

During the downward pressing of the rotary mold 1, the center column 8 will be inserted into the hole at the center position of the wheel hub, and the fixed column 9 will be inserted into one of the small holes. After the two blocks 11 are squeezed by force, they will slide into the inside of the cavity 10. When the two blocks 11 are offset from the inner side of the wheel hub, they will pop outward under the influence of the elastic force of the spring 12, so that the fixed column 9 will not be easily detached from the wheel hub.
