Therefore, the telescopic length and telescopic time of the two second electric telescopic rods 209 are the same, ensuring that the clamping center of the two positioning clamping strips 207 and the central area of ​​the forming mold 202 are at the same point, thereby ensuring that the central area of ​​the metal sheet when fixed is at the same point as the central area of ​​the forming mold 202 and the rubber suction cup 403.

[0025] Furthermore, the pressure-applying mechanism 3 includes a second slide groove 301 disposed at the bottom edge of the spinning base 1 , and a movable bracket 302 is slidably disposed on the inner wall of the second slide groove 301 .

[0026] A connecting frame 303 is rotatably provided at the top of the movable bracket 302, and a pressure module 304 is rotatably provided at one end of the connecting frame 303. The connecting frame 303 can rotate on the movable bracket 302, and the pressure module 304 can rotate on the connecting frame 303, so that when the pressure is applied to the plate, the position can be adjusted according to the shape of the forming mold 202 to contact the plate, so that the plate is more closely fitted to the forming mold 202, thereby improving the spinning quality;
