A motor (not shown in the attached figure) is connected to the bottom of the frame 1. The power output end of the motor is connected to the driving pulley. A belt drive is connected to the driving pulley and the driven pulley. A turntable 9 is connected to the top of the main shaft 2. The mold 3 is connected to the turntable 9.
[0024] The left and right thrust devices are the left forming thrust cylinder 10 and the right forming thrust cylinder 11, respectively. The power output ends of the left forming thrust cylinder 10 and the right forming thrust cylinder 11 are both connected to a base. The left forming roller 4 and the right forming roller 5 are rotatably connected to the left forming thrust cylinder 10 and the right forming thrust cylinder 11, respectively.
[0025] The vertical thrust device is an upper forming thrust cylinder 12. A column 13 is connected to the frame 1, and a crossbeam 7 is connected to the top of the column 13. The power output end of the upper forming thrust cylinder 12 is connected to a lifting plate 14. A guide rod 15 is connected between the crossbeam 7 and the frame 1. The lifting plate 14 is slidably engaged with the guide rod 15 through a guide sleeve.
[0026] The bottom of the lifting plate 14 is connected to a rotating seat 16, and the top of the support plate 17 is connected to a rotating shaft 18. The rotating shaft 18 is rotatably connected to the rotating seat 16, and the upper forming roller 6 is rotatably connected to the bottom of the support plate 17.
[0027] The bottom end of the support plate 17 is connected to three bearing seats 19.

[0029] Example 2: This example is a further improvement on Example 1.

Specifically: The mold 3 includes a lower mold 302 and an upper mold 301. The lower mold 302 is connected to the turntable 9. The top of the lower mold 302 is provided with a groove, and the upper mold 301 is engaged with the groove.

[0031] The specific working principle of this utility model is as follows: The aluminum wheel blank is placed on mold 3. The motor drives the main shaft 2 to rotate, which in turn drives the mold and the aluminum wheel blank to rotate. First, the upper forming thrust cylinder 12 drives the upper forming roller 6 to move downwards and extrude the mounting surface and spokes of the wheel hub 23. Then, the left forming thrust cylinder 10 and the right forming thrust cylinder 11 drive the left forming roller 4 and the right forming roller 5 to jointly extrude the aluminum wheel blank, resulting in a product with the same curve as the finished product. After the spinning process is completed, the upper forming thrust cylinder 12, the left forming thrust cylinder 10, and the right forming thrust cylinder 11 retract, the lifting cylinder extends, and the aluminum alloy wheel hub 23 separates from the lower mold 302, making it easy for operators to remove it.
