At the same time, after the rotating shaft 5051 is inserted into the metal pipe, the guide sleeve 5072 is pushed to rotate each side arm 5055, which is convenient for cutting metal pipes of different diameters, and multiple cutting blades are cut at the same time to improve the cutting speed. The inner side of the mouth frame 401 is provided with a mounting plate 402 at equal angles, and two clamping rods 404 are symmetrically installed on one side of the mounting plate 402 close to the metal pipe. When the metal pipe is installed, the position where the metal pipe needs to be cut needs to be adjusted between the two clamping rods 404 to avoid damage to the clamping rod 404 by the cutting knife during the cutting process. At the same time, when the pipe is cut, both sides of the cutting position can be clamped to improve the cutting stability.

[0041] Working principle: When working, firstly, the metal pipe to be cut is set inside the die frame 401, so that the position to be cut is moved between the two clamping rods 404, and then each clamping cylinder 405 is turned on to make each mounting plate 402 approach each other synchronously, so that each clamping rod 404 outside the metal pipe clamps and fixes the metal pipe, and makes the central axis of the metal pipe coincide with the central axis of the die frame 401, so as to center the metal pipe and facilitate cutting, and then the supporting cylinder 3 is turned on to make each supporting plate 2 move upward to support the metal pipe and improve cutting stability;

[0042] Then, the driving motor 504 is turned on to rotate the screw rod 503, which is threadedly connected to the mounting frame 501, thereby driving the mounting frame 501 to move along the sliding frame 502 toward the side of the die frame 401, so that the rotating shaft 5051 is inserted into the metal pipe until the end block 5053 moves to the required cutting position, and then the pushing cylinder 5077 is turned on to push the moving plate 5075 to move toward the side of the die frame 401, thereby pushing the guide sleeve 5072 to move along the guide strip 5071 toward the side of the end block 5053. The push block 50510 is pushed to move along the cross slot 5059 toward the side away from the end block 5053 through the connecting rod 5073, and then the side arm 5055 is pushed to rotate upward through the longitudinal push rod 5057 until the cutting blade on the cutting tool 5056 contacts the inner wall of the metal pipe. In this process, the connecting rod 5073 pushes the movable pipe 5067 to move outward along the fixed pipe 5066, so that the end of the movable pipe 5067 is close to the cutting inner wall of the metal pipe, which is convenient for cutting waste gas treatment of metal pipes with different diameters;

[0043] During the cutting process, the suction fan 50610 is turned on, and the suction fan 50610 is connected to the connecting sleeve 5068 through the connecting pipe 5069, and the connecting sleeve 5068 is connected to the connecting hole 5062, thereby driving the outside air to enter the circulation chamber 5061 through the movable pipe 5067 and the fixed pipe 5066 and flow toward the end of the circulation chamber 5061 away from the end block 5053, and the metal debris and dust in the exhaust gas are filtered through the filter plate 5065, so as to facilitate the treatment of the exhaust gas. After the cutting is completed, the mounting frame 501 is moved back and the fixed plate 5063 is pulled out, so that the filter plate 5065 pushes the filtered metal debris and dust to be discharged from the end of the circulation chamber 5061, so as to facilitate the discharge of the filtered material.
