[0053] The staff places all the pipes to be cut onto the pipe supply device 2, then starts the pipe supply device 2, outputting one pipe to the temporary storage rack 3. Then, the pushing mechanism 31 is activated to push the pipe on the temporary storage rack 3 towards the baffle, so that one end of the pipe abuts against the temporary storage rack 3. Then, the two sets of gripping devices 4 are activated and operate synchronously to grab the pipe from the temporary storage rack 3 and place the pipe between the two sets of cutting mechanisms 5. The moving slide of the cutting mechanism is activated so that each disc-shaped cutting blade 57 is in contact with the outside of the pipe. Each cutting rotation motor 54 is activated to drive the disc-shaped cutting blade 57 to rotate at high speed. Then, the telescopic unit 55 is activated so that the disc-shaped cutting blade 57 penetrates the side wall of the pipe. The cutting rotation motor 54 is activated so that the disc-shaped cutting blade 57 moves in a reciprocating arc-shaped circular motion with a point on the pipe axis as the center, through the arc-shaped rack 52, thereby cutting the pipe.

The gripper slide 41 drives the gripper mechanism 47 to move towards the pipe until the gripper mechanism 47 is directly above the pipe. The gripper lifting unit is activated, driving the gripper mechanism 47 to move down, and then the gripper mechanism 47 grips the pipe. After the gripper mechanism 47 grips the pipe, the pipe is moved between the two sets of cutting mechanisms 5 through the gripper slide 41 and the gripper lifting unit. The support plate 45 is dragged from below the pipe by the support plate sliding unit 43 and the support plate rotating unit 44.

[0071] Two gripping devices 4 are provided; a translation unit 49 is fixedly installed on the mounting frame 1. The translation unit 49 has two output ends, and a gripper slide mounting frame 48 is fixedly installed on each output end; each gripper slide 41 is fixedly installed on the corresponding gripper slide mounting frame 48; the lateral movement of the gripping device 4 is realized through the translation unit 49, and the feed is realized when cutting the pipe by cooperating with the gripping device 4.

[0072] Working principle: The operator places the pipe to be cut onto the pipe supply device 2, which then sequentially transports the pipes one by one to the temporary storage rack 3. After the pipe supply device 2 transports a pipe to the temporary storage rack 3, the push cylinder 311 is activated, pushing the pipe toward the baffle via the push plate 312, so that the end of the pipe abuts against the baffle (ensuring that after the gripping device 4 grips the pipe and places one end between the two sets of cutting mechanisms 5, the distance between the cutting mechanism 5 and the end of the pipe is a certain length, and the pipes are all of equal length from the factory). Subsequently, the gripper slide 41 is activated, driving the gripper mechanism 47 to move directly above the pipe. At the same time, the support plate sliding drive motor 432 and the support plate rotation drive motor 442 are activated, driving the support plate 45 to move downward and rotate toward the side, preventing the gripper mechanism 47 from being affected when gripping the pipe.

[0073] Start the temporary storage rack drive motor 35, which drives the temporary storage rack 3 to move upward; start the gripper lifting motor 463, which drives the gripper mechanism 47 to move downward. When the sensor on the limit block 474 contacts the pipe, the bidirectional telescopic cylinder 471 starts, which drives the two gripper execution plates 473 to move inward at the same time to clamp the pipe. The gripper lifting motor 463 starts again, which drives the gripper mechanism 47 to move upward. At the same time, the support plate rotation drive motor 442 drives the support plate 45 to rotate, so that the support plate 45 rotates to be directly below the pipe. Then the support plate sliding drive motor 432 starts, which drives the support plate 45 to move upward until the proximity switch is triggered. The support plate 45 stops moving upward, and at this time the support plate 45 supports the pipe from below, and the upper surface of the support plate 45 contacts the pipe.

[0074] The pipe is gripped between the two sets of cutting mechanisms 5 by means of the gripper lifting motor 463, the support plate sliding drive motor 432, and the gripper slide 41. The lifting frame 51 is activated to make the rotation center of the two sets of cutting mechanisms 5 as close as possible to the axis of the pipe (since the radius of the disc-shaped cutting blade 57 is much larger than the wall thickness of the pipe, the center of the two sets of cutting mechanisms 5 does not need to coincide with the axis of the pipe). Then the receiving slide moves the receiving execution group into the pipe and activates the inner support plate drive cylinder 64 to make the receiving execution plate 67 open outward, so that the receiving execution plate 67 supports the pipe from the inner wall of the pipe.

[0075] Depending on the required cutting length, the clamping mechanism 7 at the rear end releases the pipe (at this time, the pipe is supported by the clamping mechanism 7 at the front end and the receiving support device 6), and moves a certain distance backward through the translation unit 49, and the clamping mechanism 7 clamps the pipe again; the clamping mechanism 7 at the front end releases the pipe, and the clamping mechanism 7 at the rear end and the receiving execution group move forward synchronously a certain distance, and then the clamping mechanism 7 at the front end clamps the pipe again, and the cutting mechanism 5 is started to cut the pipe. After the cutting is completed, it moves to the discharge conveyor belt through the receiving support device 6, and the discharge conveyor belt transports the cut pipe away.
