The bottom end of the turbine 20 is meshed with a turbine rack 19. Since the tooth profiles of the front and rear turbines 20 are consistent and distributed on the front and rear sides of the worm 18, the rotation directions of the two turbines 20 are opposite, and the worm 18 rotates clockwise. The rotation will be transmitted to the turbine rack and gear 19 through the two turbines 20, causing the front and rear turbine rack and gear 19 to move inward together. A sliding block is welded to the bottom end of the turbine rack and gear 19. The center position of the sliding plate 6 is interference-fitted with a rectangular groove along the front-to-back direction.

[0038] As a preferred solution, further, a threaded hole 5 is opened at the bottom end of the sliding plate 6 along the left and right directions, and the second screw 17 moves clockwise through the threaded hole 5 to drive the left and right sliding plates 6 to move inward at the same time.
[0039] A rolling method for a seamless pipe short-process rolling device, the method comprising:
[0040] S1. Place the pipes in the grippers 21 on the left and right sides respectively, and the grippers 21 tighten the pipes on both sides;
[0041] S2, start the second reduction motor 16, at this time the sliding plate 6 drives the pipes on the left and right sides to move toward each other until the pipes on the left and right sides are close to each other;
[0042] S3, start the first reduction motor 4, and then the pipe press 8 reciprocates to roll the pipe into shape.
[0043] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.
[0044] When the pipe needs to be rolled and spliced, first insert the wire to be rolled and spliced into the inner side of the clamping hands 21 of the inner cavity of the left and right sliding plates 6, then turn on the external power supply to make the third reduction motor 14 rotate clockwise, and the third reduction motor 14 drives the worm 18 to rotate clockwise, and the clockwise rotation of the worm 18 drives the front and rear turbines 20 to rotate. Since the tooth profiles of the front and rear turbines 20 are consistent and distributed on the front and rear sides of the worm 18, the rotation directions of the two turbines 20 are opposite. The clockwise rotation of the worm 18 will be transmitted to the turbine rack 19 through the two turbines 20, so that the front and rear turbine racks 19 move inward together. The two turbine racks 19 move inward together, and the clamping hands 21 with rubber strips will clamp the pipe through the slider. At this time, the second reduction motor is started. 16. The second reduction motor 16 drives the second lead screw 17 to move clockwise. The clockwise movement of the second lead screw 17 drives the left and right sliding plates 6 to move inward at the same time through the action of the thread, and finally the pipes on the left and right sides are tightly fitted together. At this time, the first reduction motor 4 is connected to the external power supply. At this time, the first reduction motor 4 rotates clockwise, and the first reduction motor 4 drives the first lead screw 10 to move clockwise. The clockwise movement of the first lead screw 10 drives the left and right sliding blocks 11 to move inward at the same time through the action of the thread. The left and right sliding blocks 11 move inward at the same time and push the movable plate 13 downward through the push rod 12. Finally, the reciprocating motion of the pipe presser 8 is realized to roll the pipe. The rolling effect is good, the qualified rate is high, the structure is simple and reasonable, the applicability is strong, and it is beneficial to promote and use.
