Description

Technical Field

[0002] Steel pipes can be used in a variety of environments because of their hard texture, non-corrosion, high temperature resistance and high pressure resistance. When processing steel pipes into target pipe fittings, they generally need to be cut. At present, most of them are cut manually using electric saws or other cutting tools. When using manual cutting, the labor intensity of the cutters is very high, resulting in low cutting efficiency. In addition, manual cutting is difficult to ensure the cutting quality, which easily leads to the scrapping of steel pipes and increases the processing cost of pipe fittings.

[0039] The movable push plate 18 is mounted on the guide rod 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 2 32 will be pushed to the side of the support frame 4 under the action of the push, prompting the other end of the steel pipe to 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.

[0040] One end of the steel pipe is clamped firmly by the elastic semicircular clamping block 35. Then, as it is pushed forward, the other end is pushed against the side of the support column 1 3. The inner wall of the conveyed steel pipe is supported by the push rod 14 on the side, achieving the function of limited clamping. Then, as the threaded rod 22 is running, the force-dividing push plate 25 is always allowed to push against the side wall of the movable push plate 18, so that the support frame 2 32 and the movable push plate 18 remain separated. When the cutting part 7 is cutting the steel pipe, the steel pipe will generate a large amount of vibration force. After the vibration force is transmitted to the position of the support frame 2 32, it will cause it to break. The generated force will not be directly applied to the movable push plate 18. The movable push plate 18 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 slipping during the cutting operation.

[0041] Detailed usage and effects of this embodiment:

[0042] The steel pipe is erected in the first semicircular groove 15 and the elastic semicircular clamping block 35. Due to the elastic action of the elastic semicircular clamping block 35, one side of the steel pipe erected inside is clamped firmly. Then, the cylinder 20 and the gas rod 19 are driven to generate a telescopic movement. The gas rod 19 pushes the mobile push plate 18 to be transported forward. The mobile 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 2 37 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 leather 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 externally sleeved inverted T-shaped column 24. When the right side of the force-dividing top plate 25 presses against the side wall of the movable push plate 18, the force-dividing top plate 25 will produce a trajectory of sliding to the left, prompting 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 push plate 18 is pushed to the left, the force-dividing top plate 25 is still against the 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 carried to the left. Among them, 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 drive motor 1 62 is running, and the motor 1 62 drives the main pulley. As the third pulley 63 rotates, the primary pulley 3 63 drives the secondary pulley 4 64 to rotate via the belt 3 65, and the secondary pulley 4 64 drives the connected sprocket 66 to rotate, and the sprocket 66 drives the other connected sprockets 66 to rotate together via 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 internally inserted limiting rod 2 13. 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 pushed steel pipe to support the inner wall of the left side of the steel pipe firmly. In this way, the entire steel pipe will be limited, and at the same time, the horizontal state of the steel pipe installation can be adjusted to keep the steel pipe balanced.

[0043] The cutting motor provided inside the driving support column 3 drives the main pulley 2 70 connected to one side when the cutting motor is running. After the main pulley 2 70 rotates, it will drive the main pulley 2 70 provided on the other side to rotate through the belt 2 69. The connecting block 68 connected to the upper part of the belt 2 69 will carry the movable support plate 51 connected to the upper part, and the slider 71 at the bottom of the movable support plate 51 will slide to one side in the track 50. During the sliding process, the driving motor 2 55 is operated, and the motor 2 55 drives the guide rod 3 6 to rotate. After the guide rod 3 6 rotates, the vortex rod 54 provided on the upper part will rotate along with it, and the vortex rod 54 drives the meshing turbine 53 below to rotate. The turbine 53 will drive the saw blade 56 connected to the side, and the saw blade 56 will cut the steel pipe installed below from one side to the other side. In this way, multiple steel pipes can be cut at the same time, thereby increasing the cutting efficiency.

[0044] During the cutting process, the water pump inside the water tank 58 is turned on to extract the water inside the water tank 58 and transport it to the sprinkler head 61 through the conduit 60. The sprinkler head 61 will always spray the saw blade 56 to facilitate the saw blade 56 to perform cutting operations.

[0045] The above specific embodiments will allow those skilled in the art to easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific embodiments. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to implement different technical solutions.
