Spinned wheels maintain sufficient strength while significantly reducing material thickness, thus lightening the wheel's weight.

[0003] A search revealed a patent with application number 202021114633.2, which discloses an aluminum alloy wheel hub spinning machine, comprising a frame, spindle box, pressure cylinder, mold assembly, cutter holder, roughing cutter, and finishing cutter.

The output shaft of the drive motor 7 passes through the inverted U-shaped bracket 6.

[0029] Specifically, the servo control component includes a servo motor 10 fixed to the lower outer wall of one side of the spinning machine body 1 by bolts, a worm gear 11 fixedly mounted on the output shaft of the servo motor 10, and a worm wheel 12 fixedly mounted on the bidirectional screw 2 and meshing with the worm gear 11.

[0030] Furthermore, linear bearings 9 are fixedly embedded in both adjusting rods 3, and both linear bearings 9 are movably connected to the guide horizontal shaft 4, which can ensure the stability and smoothness of the linear movement of the two adjusting rods 3.

[0031] In this embodiment, the servo motor 10 drives the worm gear 11 to rotate, and the worm wheel 12 meshing with the worm gear 11 controls the rotation of the bidirectional screw 2.

This can better meet the diverse processing needs of different aluminum alloy wheel hubs.

[0032] Example 2, refer to Figure 1 and Figure 4 This embodiment is an optimization based on embodiment 1, specifically:
