The implementation principle of the embodiment is as follows:

the conveying motor 25 is started, the conveying motor 25 drives the conveying belt 24 to convey the workpiece, and when the workpiece which is subjected to plastic forming is conveyed to a preset position through the conveying belt 24, the conveying motor 25 stops rotating to enable the workpiece to stay at the preset position. Subsequently, the displacement motor 314 is started, the displacement motor 314 rotates to drive the displacement gear 315 to rotate, and since the displacement gear 315 is meshed with the displacement rack 316 fixedly installed on the rack 1, the displacement gear 315 rotates to drive the displacement plate 311 to slide along the displacement slot 313, and at the same time, the displacement wheel 312 rolls in the displacement slot 313 to reduce the friction force between the displacement plate 311 and the rack 1.

When the displacement plate 311 is driven by the displacement motor 314 to move the water smoothly above the workpiece, the displacement motor 314 stops rotating. Then, the lifting motor 41 is started, the lifting gear 42 rotates when the lifting motor 41 rotates, and on one hand, the lifting motor 41 drives the lifting rod 45 meshed with the lifting gear to vertically move up and down; on the other hand, the transmission gear 53 engaged with the transmission gear is driven to rotate, the driving force is transmitted to the transmission gear 53 far away from the material receiving end through the transmission rod 52, and the transmission gear 53 far away from the material receiving end drives the lifting rod 45 engaged with the transmission gear to vertically move up and down. In the process, the limiting roller 44 rolls with the lifting rod 45 to reduce friction force, and the lifting rod 45 is pushed to the lifting gear 42 or the transmission gear 53, so that the two gears are meshed more stably.

The lifting rod 45 vertically moves up and down to drive the adsorption pipe 6 arranged on the lifting rod 45 to vertically move up and down, and the adsorption pipe 6 drives the sliding rod 71 to slide in the sliding ring 72, and the sliding ring 72 can limit the position of the lifting rod 45 through the sliding rod 71 to ensure that the lifting rod is stably meshed with the lifting gear 42 or the transmission gear 53 because the position of the sliding ring 72 is fixed.
