The transfer mechanism 9 is used to transport the steel pipe on the receiving rack 8 to the space between the left fixed block 16 and the left movable block 17 and between the right fixed block and the right movable block.

[0075] The left clamping drive component 18 is connected to the left movable block 17 and is used to drive the left movable block 17 to move toward the left fixed block 16 so that the left fixed block 16 and the left movable block 17 clamp the steel pipe;

[0076] The right clamping drive component is connected to the right movable block and is used to drive the right movable block to move toward the right fixed block so that the right fixed block and the right movable block clamp the steel pipe; specifically, when the steel pipe is cut, the left clamping drive component 18 drives the left movable block 17 to move to release the steel pipe, and the right clamping drive component drives the right movable block to move to release the steel pipe; further specifically, the left clamping drive component 18 and the right clamping drive component are both connected to the main frame, and the left clamping drive component 18 and the right clamping drive component are both hydraulic cylinders.

[0077] like Figure 1 , 2 As shown, the cutting mechanism 7 may include a lifting seat 19, a lifting drive mechanism, a cutting motor 20, and a saw blade 21;

[0083] One end of the first rotating arm 23 and one end of the second rotating arm 24 are respectively rotatably connected to the main frame;

[0084] The material support plate 22 is provided with a first groove 25 for supporting the steel pipe on the receiving frame 8 and a second groove 26 for supporting the steel pipe cut in the main clamping mechanism 6. The material support plate 22 is hinged to the other end of the first rotating arm 23 and the other end of the second rotating arm 24 respectively. The first rotating arm 23 and the second rotating arm 24 are parallel and have the same length.

[0085] The transfer drive assembly is connected to the first rotating arm 23 and is used to drive the first rotating arm 23 to rotate, thereby driving the material support plate 22 to move, so as to lift and transport the steel pipe on the receiving rack 8 to the main clamping mechanism 6, and to lift and transport the cut steel pipe in the main clamping mechanism 6 to the conveying mechanism 10. Specifically, the transfer drive assembly can be a stepper motor. During the movement of the material support plate 22, it will lift the steel pipe on the receiving rack 8 through the first groove 25 and lift the cut steel pipe in the main clamping mechanism 6 through the second groove 26. As the material support plate 22 continues to move, the steel pipe in the first groove 25 will be transported to the main clamping mechanism 6, and the steel pipe in the second groove 26 will be transported to the conveying mechanism 10. In this embodiment, the middle cutting and transferring device 5 is provided with two transferring mechanisms 9.

[0103] like Figure 1 , 2 As shown, at least one auxiliary transfer device 35 is also provided between adjacent cutting and transfer devices 5. The auxiliary transfer device 35 includes an auxiliary frame and an auxiliary clamping mechanism. The auxiliary clamping mechanism is connected to the auxiliary frame and is used to clamp and release the steel pipe synchronously with the main clamping mechanism 6. The receiving frame 8, the transfer mechanism 9, the conveying mechanism 10, and the unloading mechanism 11 are also connected to the auxiliary frame. Specifically, the receiving frame 8 on the auxiliary frame is used to receive and support the steel pipe together with the receiving frame 8 on the main frame. The transfer mechanism 9 on the auxiliary frame is used to move synchronously with the transfer mechanism 9 on the main frame to transport the steel pipe. The conveying mechanism 10 on the auxiliary frame is used to transport the steel pipe to the unloading mechanism 11 together with the conveying mechanism 10 on the main frame. The unloading mechanism 11 on the auxiliary frame is used to transfer and transport the steel pipe to the second transfer device 4 synchronously with the unloading mechanism 11 on the main frame. More specifically, the auxiliary clamping mechanism includes a clamping cylinder, a first clamping block, and a second clamping block. The first clamping block is fixedly connected to the auxiliary frame, and the second clamping block is connected to the clamping cylinder. The clamping cylinder is connected to the auxiliary frame and is used to drive the second clamping block to move to clamp the steel pipe onto the first clamping block.

[0105] The auxiliary frame in the auxiliary transfer device 35 and part of the main frame in the cutting transfer device 5 are slidably connected to the guide rail component along the length of the steel pipe.

[0106] A travel motor is connected to both the main frame and the auxiliary frame, which are slidably connected to the guide rail component. A travel gear is connected to each travel motor and meshes with the rack. Specifically, when the travel motor drives the travel gear to rotate, the travel gear engages with the rack, thereby moving the auxiliary frame and part of the main frame along the length of the steel pipe into position. This allows adjustment of the positions of the auxiliary transfer device 35 and part of the cutting transfer device 5. In this embodiment, the main frame of the front cutting transfer device 5 is fixedly mounted on the ground, while the main frames of the rear and middle cutting transfer devices 5 are slidably connected to the guide rail component.

[0107] In summary, after the feeding conveying device 1 moves the steel pipe into position, the first transferring device 3 lifts the steel pipe moved into position on the feeding conveying device 1 and transports it to the receiving rack 8. At this time, the receiving racks 8 on each main frame support the steel pipe. Then, the transfer mechanisms 9 on each main frame operate synchronously to transport the steel pipe on the receiving rack 8 to the main clamping mechanism 6. Then, the main clamping mechanisms 6 on each main frame clamp the steel pipe. Then, the cutting mechanisms 7 on each main frame cut the clamped steel pipe. Then, the main clamping mechanisms 6 release the steel pipe. At this time, the transfer mechanisms 9 on each main frame operate synchronously again to transport the cut steel pipe in the main clamping mechanism 6 to the conveying mechanism 10, and at the same time, transport the next steel pipe that has been conveyed to the receiving rack 8 to the main clamping mechanism 6. The conveying mechanisms 10 on each main frame operate synchronously to transport the steel pipe to the unloading mechanism 11. The unloading mechanisms 11 on each main frame then synchronously transfer the steel pipe to the second transferring device 4. The second transferring device 4 then lifts the steel pipe and transports it to the discharge conveying device 2, which then transports it to subsequent processing steps. This process automates the loading, cutting, and unloading of steel pipes, significantly improving the automation and efficiency of steel pipe cutting while reducing labor intensity and costs.
