[0103] and a spring 206, with two ends of the spring 206 fixedly connected to the special-shaped stopper 205 and the V-shaped plate 201 respectively.

[0104] The specific working process of the present invention is as follows:

[0105] I. Loading

[0106] The initial state of the device is that the two upper connecting rods 302 are in a horizontal state. At this time, the V-plate unit 2 is docked with the loading pipeline, and the blank can be directly transported to the V-shaped plate 201 through the loading pipeline. During the transportation of the blank, it collides with the inclined surface of the special-shaped stopper 205. At this time, the special-shaped stopper 205 rotates around the stepped shaft for the stopper, enabling the blank to move forward smoothly. After the blank completely passes through, the special-shaped stopper 205 is reset under the action of the spring 206. Press the loading switch on the console 505, and the cylinder rod of the cylinder 314 contracts, driving the rear upper shaft 307 to rotate through the cylinder connecting plate 318. The rear upper shaft 307 then drives the two upper connecting rods 302 to rotate. Through the action of the double parallelogram mechanism, the V-plate unit 2 at one end rises in a curve. When the cylinder plate 316 touches the up-travel switch 504, the cylinder rod of the cylinder 314 stops contracting. At this time, the blank is located at the designated position of the spinning machine.

[0107] II. Unloading

[0108] After spin forming, the spin-formed product is conveyed onto the V-shaped plate 201. During the conveying process, the spin-formed product collides with the special-shaped stopper 205. The special-shaped stopper 205 cannot rotate due to the obstruction of the V-shaped plate 201. Therefore, the spin-formed product can be moved to the fixed position of the V-plate unit 2. After reaching the fixed position, press the blanking switch of the control console 505, and the rod of the cylinder 314 extends, causing the V-plate unit 2 to descend in a curve. When the lower connecting rod 303 touches the down-stroke switch 502, the rod of the cylinder 314 stops extending. At this time, the upper connecting rod 302 is in a horizontal state. At the same time, the motor 411 rotates counterclockwise. Through the transmission of the coupling 410, the first flipping stepped shaft 402, and the first flipping gear 405, one gear threaded bushing 306 rotates clockwise. Through the transmission of the first belt pulley 407, the first synchronous belt 409, the second belt pulley 408, the second flipping stepped shaft 404, and the second flipping gear 406, the other gear threaded bushing 306 rotates clockwise synchronously. Both ends of the two gear threaded bushings 306 have left-handed threads on the left end and right-handed threads on the right end. The left sections 304 of the two lower connecting rods 303 are all left-handed threads, and the rest are right-handed threads. Therefore, when the gear threaded bushing 306 rotates clockwise, the lower connecting rod 303 in the parallelogram mechanism shortens synchronously, causing the V-shaped plate 201 to flip. While the motor 411 rotates, the first flipping stepped shaft 402 drives the worm gear 420 to rotate counterclockwise. The worm gear 420 and the worm 419 are left-handed, so the worm 419 rotates counterclockwise. Through the transmission of the fourth belt pulley 416, the second synchronous belt 417, the third belt pulley 415, and the friction shaft 413, the friction wheel 414 rotates counterclockwise. The friction wheel 414 contacts the spin-formed product through the long hole 202 of the flipping V-shaped plate 201, thereby rolling it out of the V-shaped plate 201 and falling onto the blanking production line for conveyance. At this time, the motor 411 rotates in reverse to reset the V-shaped plate 201 to the initial position. The number of turns of the forward and reverse rotations of the motor 411 is the same and is a fixed value, which is controlled by the encoder and the PLC. After the V-shaped plate 201 is reset to the initial position, the blanking process ends.
