The cylindrical linear guide rails 16 are horizontally mounted and arranged perpendicularly to the guide rails 1. The sawing mechanism is horizontally slidably mounted on the two cylindrical linear guide rails 16.

[0021] The sawing mechanism includes a motor base plate 4 slidably mounted on a cylindrical linear guide rail 16, a motor 5 fixedly mounted on the upper end of the motor base plate 4, and a saw blade 14 driven and connected to the motor 5. The motor base plate 4 is horizontally mounted, and a plurality of linear bearings 15 are evenly fixedly mounted on the bottom end of the motor base plate 4. The linear bearings 15 are slidably connected to the cylindrical linear guide rail 16.

[0022] A saw blade protective cover 6 is fixedly installed on the outside of the saw blade 14. The saw blade protective cover 6 is fixedly connected to the base 2. A through hole is provided on the saw blade protective cover 6, and a copper tube passes through the through hole.

[0023] The moving mechanism includes a cylinder 13 horizontally fixedly mounted on the upper end of the base 2, a cylinder connecting block 12 fixedly connected to the telescopic end of the cylinder 13, the cylinder connecting block 12 fixedly connected to the bottom end of the motor base plate 4, and the cylinder 13 being arranged parallel to the cylindrical linear guide rail 16.

[0024] The upper end of the base is fixedly provided with guide nozzle frame 1 7 and guide nozzle frame 2 11. Guide nozzle 1 8 and guide nozzle 2 10 are respectively fixedly and coaxially on guide nozzle frame 1 7 and guide nozzle frame 2 11. Copper tubes are inserted through guide nozzle 1 8 and guide nozzle 2 10. Guide nozzle 1 8 and guide nozzle 2 10 are coaxially arranged with the through hole.

[0026] The specific working process of this utility model:

[0027] The copper pipe cutting device is equipped with copper straight pipe conveying equipment at the front and rear. When this utility model is working, the base 2 located on the guide rail 1 is fixed first. Then, the conveying equipment continuously conveys the copper pipe to the cutting device, so that the copper straight pipe passes through the guide nozzle frame 2 11 and the guide nozzle frame 1 7 in sequence, and the guide nozzle 2 10 and guide nozzle 1 8. After the copper straight pipe passes through the guide nozzle 2 10 and guide nozzle 1 8 in sequence, the copper pipe cutting device is started. At this time, the motor 5 runs at low speed.

[0028] After the copper straight tube reaches the set length, the motor 5 runs at high speed. At the same time, the telescopic end of the cylinder 13 extends, driving the cylinder connecting block 12 to move. The cylinder connecting block 12 drives the motor base 4, which is fixedly connected to it, to move, so that the motor base 4 slides along the cylindrical linear guide rail 16 set on the guide rail bracket 3 under the guidance of the linear bearing 15.

[0029] At the same time, the motor base 4 drives the motor 5 and the saw blade 14 driven by the motor 5 to approach the guide nozzle 8 together. After the cylinder 13 reaches its maximum stroke at the extension end, the saw blade 14 just cuts the copper straight pipe passing through the guide nozzle 8 and the guide nozzle 10.

[0030] After the saw blade 14 cuts the copper straight pipe, the telescopic end of the cylinder 13 retracts, causing the cylinder connecting block 12 and the motor base 4 to slide along the cylindrical linear guide rail 16 set on the guide rail bracket 3 under the guidance of the linear bearing 15. At the same time, the motor base 4 drives the motor 5 and the saw blade 14 to reset together. At this time, the motor 5 resumes low-speed operation, and one cutting action is completed. Then, the above actions are repeated to achieve repeated cutting of the copper straight pipe.
