When cutting steel pipes, two steel pipes to be cut are placed on the arc groove on the bottom plate, and the cutting disc and the arc plate are moved downward by a hydraulic cylinder. The arc plate will tightly press the steel pipe in the arc groove under the action of a spring, and then the cutting disc will contact the steel pipe. The cutting disc is rotated at high speed by a motor to cut the steel pipe, and the position of the cutting disc is controlled by pushing the cross bar forward and backward, so that the two steel pipes can be flexibly cut, and the purpose of cutting two steel pipes at the same time is effectively achieved.

[0053] When it is necessary to clamp the steel pipe, the transmission frame telescopic rod 74 is shortened to drive the transmission frame support block 75 to move. When the transmission frame support block 75 moves and drives the transmission frame movable block 76 to move synchronously, the transmission frame movable clamping block 77 moves in the direction of the transmission frame fixed clamping block 73 to clamp the steel pipe. The fixed frame telescopic rod 84 is shortened to drive the fixed frame support block 85 to move. When the fixed frame support block 85 moves and drives the fixed frame movable block 86 to move synchronously, the fixed frame movable clamping block 87 moves in the direction of the fixed frame fixed clamping block 83 to clamp the steel pipe. After the transmission fixing mechanism 7 and the movable fixing mechanism 8 fix the steel pipe, the transmission fixing mechanism 7 and the movable fixing mechanism 8 can be synchronously driven when the steel pipe moves. The fixed mechanism 8 moves, and the transmission frame connecting block 72 of the transmission fixing mechanism 7 is fixedly connected to the cutting mobile platform.

During the movement of the steel pipe, the connecting telescopic rod 92 extends, and the cutting mechanism 4 cuts the steel pipe during the movement. When the steel pipe is cut and separated, the connecting spring 96 extends. After the connecting spring 96 extends, the distance between the fixed connection block 94 and the movable connection block 93 increases.

The movable fixing mechanism 8 transports the cut steel pipe to other mechanisms through the conveying mechanism 5, and then connects the telescopic rod 92 shortens and drives the fixed connection block 94 and the movable connection block 93 to move synchronously. When the movable connection block 93 moves, it can synchronously drive the cutting movable table 3 to move. After the cutting movable table 3 stops moving, the movable connection block 93 cannot continue to move. The connecting telescopic rod 92 continues to shorten and drives the fixed connection block 94 and the spring connection block 95 to move, thereby shortening the distance between the fixed connection block 94 and the movable connection block 93 and compressing the connecting spring 96.

[0065] After the steel pipe cutting is completed, the transmission fixing mechanism 7 moves in the direction away from the movable fixing mechanism 8, so that the lifting sleeve 101 and the second pulley 1010 move in the direction close to the connecting slider 1011, thereby loosening the cleaning connecting rope 108. After the cleaning connecting rope 108 is relaxed, the lifting spring 102 and the telescopic spring 106 extend to drive the lifting rod 103 to rise and make the cleaning module 107 extend to clean the burrs on the cut of the steel pipe. Since the elastic coefficient of the lifting spring 102 is greater than the elastic coefficient of the telescopic spring 106, the cleaning module 107 will extend from the inside of the telescopic sleeve 105 after the lifting rod 103 rises, and the connecting slider 1011 is retracted when the distance between the transmission fixing mechanism 7 and the movable fixing mechanism 8 is shortened. To the inside of the transmission frame body 71 and the fixed frame body 81, and move the lifting sleeve 101 and the second pulley 1010 in the direction away from the connecting slider 1011 to tighten the cleaning connecting rope 108.
