When the movable push plate on one side is pushed, the clamped steel pipe in the elastic semicircular clamping block will be pushed to the other side until the other side of the steel pipe is limited on the side wall of the support column. With the limit of the top rod, it is internally limited and fixed, so that the whole steel pipe is kept on a horizontal plane while both ends are in a clamped state. Then, the cutting part effectively cuts it.

[0014] 2. When the cutting part is cutting the steel pipe, a large amount of vibration force will be generated on the steel pipe. After the vibration force is transmitted to the second position of the support frame, it will cause disconnection, and the generated force will not be directly applied to the moving push plate. The moving push plate will be more stable during the pushing movement. After the lower part of the steel pipe is stable, the stability during the erection operation will be better. This effectively prevents the phenomenon of slipping during the cutting operation.

[0015] 3. Compared with the existing steel pipe cutting, this cutting device can cut multiple steel pipes at the same time, which improves the cutting efficiency. The vibration force generated by the cutting will not be directly applied to the lower part of the steel pipe support, so that the lower part can always be kept stable, so that the steel pipe will not be affected by multi-directional vibration, and the stability of steel pipe cutting is improved.

[0024] The movable push plate 18 is mounted on the guide rods 17 on both sides. When the cylinder 20 and the gas rod 19 generate telescopic movement, the movable push plate 18 will be transported forward. In this way, the end of the steel pipe mounted on the support frame 32 will be pushed to one side of the support frame 4 under the action of the push, so that the other end of the steel pipe will be pressed against the support column 3, and then as the push rod 14 is pushed outward, the pushed end of the steel pipe will be clamped, and the angle of the steel pipe can be adjusted after clamping to keep the steel pipe on a stable horizontal plane. At this time, during the cutting operation, slipping during the cutting process will be avoided.

[0025] One end of the steel pipe is clamped firmly by the elastic semicircular clamping block 35, and then as it is pushed forward, the other end is pushed against the side of the support column 1 3, and the inner wall of the delivered steel pipe is supported by the push rod 14 on the side, so as to achieve the role of limited clamping. Then, as the threaded rod 22 is running, the force-dividing top plate 25 is always pushed against the side wall of the moving push plate 18, so that the support frame 2 32 and the moving push plate 18 are kept separated. When the cutting part 7 performs a cutting operation on the steel pipe, a large amount of vibration force will be generated on the steel pipe. After the vibration force is transmitted to the position of the support frame 2 32, it will cause a disconnection, and the generated force will not be directly applied to the moving push plate 18. The moving push plate 18 will be more stable in the pushing movement. After the lower part of the steel pipe is stable, the stability in the erection operation will be better. This effectively prevents the phenomenon of slipping during the cutting operation.

[0026] Detailed usage and function of this embodiment: The steel pipe is mounted in the first semicircular groove 15 and the elastic semicircular clamping block 35. Due to the elastic effect of the elastic semicircular clamping block 35, one side of the steel pipe mounted inside is clamped firmly, and then the cylinder 20 and the gas rod 19 are driven to produce telescopic movement. The gas rod 19 pushes the movable push plate 18 to be transported forward. The movable push plate 18 slides on the guide rod 17. At the same time, the elastic semicircular clamping block 35 will clamp one end of the steel pipe and push it forward, causing the other end of the steel pipe to press against the side wall of the support column 13. At this time, the movement between the cylinder 20 and the gas rod 19 is stopped. During the pushing process, since the left side of the guide rod 23 is fixed on the inverted T-shaped column 24, before pushing, the driver 45 is driven to run, and the driver 45 drives the main skin As the pulley 1 44 rotates, the primary pulley 1 44 drives the other secondary pulleys 1 47 and secondary pulley 2 48 to rotate through the belt 1 49. When the secondary pulley 2 48 rotates, it drives the threaded rod 22 inserted in the middle to rotate. When the threaded rod 22 rotates, it drives the internal threaded cylinder 23 to move on the threaded rod 22. When the internal threaded cylinder 23 moves to the right, the internal threaded cylinder 23 moves to the right with the inverted T-shaped column 24 set on the outside. When the right side of the force-dividing top plate 25 presses against the side wall of the moving push plate 18, the force-dividing top plate 25 will produce a trajectory of sliding to the left, causing the middle limit rod 1 27 to slide along the groove wall of the V-shaped groove 26 and be connected to the lower position of the inclined surface of the V-shaped groove 26. At this time, the bottom of the locking plate 28 is just embedded in When the movable push plate 18 is pushed to the left, the force-dividing top plate 25 is still against the movable push plate 18. At this time, the left side of the guide rod 2 37 will pass through the support frame 1 4. At the same time, the steel pipe erected between the support frame 1 4 and the support frame 2 32 is transported to the left. Since the right side of the steel pipe is clamped in the elastic semicircular clamping block 35, the right side of the steel pipe is in a stationary state. When the steel pipe is moved to the left, the steel pipe will be against the side of the support column 1 3. At this time, the driving motor 1 62 is running, and the motor 1 62 drives the main pulley. The third 63 rotates, the primary pulley three 63 drives the secondary pulley four 64 to rotate through the belt three 65, the secondary pulley four 64 drives the connected sprocket 66 to rotate, the sprocket 66 will drive other connected sprockets 66 to rotate together through the chain 67, at this time, the rotating shaft 11 connected to the sprocket 66 will rotate, after the rotating shaft 11 rotates, the arc-shaped slide groove 12 on the side of the turntable 10 will drive the limiting rod 2 13 inserted inside, after the limiting rod 2 13 moves along the arc-shaped slide groove 12, it will prompt the push rod 14 to push outward, the push rod 14 pushes against the inner wall of the steel pipe pushed over, and supports the inner wall of the left side of the steel pipe firmly, so that the entire steel pipe will be limited, and at the same time, the horizontal state of the steel pipe erection is adjusted to keep the steel pipe balanced.
