DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 As shown, the utility model provides a technical solution: a pipe cutting device, including a cutting table 1, two sets of rotatable screw rods 2 are installed on the top of the cutting table 1, the screw rods 2 are driven by an external first motor 3, and a horizontally movable fixing frame 4 is installed between the screw rods 2 by threaded cooperation, and a fixing bolt 5 for fixing the pipe is installed on the fixing frame 4. The first motor 3 can drive the pipe to move. Every time a section is cut, the pipe moves forward a section, which is convenient for continuous cutting.

[0023] like Figure 1-2As shown, a support platform 16 is disposed on the top of the cutting table 1, and the support platform 16 can serve to assist in supporting the pipe.

[0024] like Figure 3-4 As shown, an annular tool holder 6 is fixedly provided on one side of the cutting table 1, and a rotatable ring gear 7 is installed on the inner wall of the annular tool holder 6. A tool seat 8 is slidably installed on the annular tool holder 6, and a second motor 9 is arranged on the tool seat 8. A gear 10 is installed on the output end of the second motor 9, and the gear 10 meshes with the teeth on the inner side of the ring gear 7.

[0025] like Figure 3 As shown, a retractable cylinder 11 is arranged in the knife seat 8, a third motor 12 is installed at the free end of the cylinder 11, and a blade 13 is installed at the output end of the third motor 12.

[0026] like Figure 2 As shown, a shielding cover 14 and a cleaning brush 15 are respectively provided on the hood of the third motor 12 . The shielding cover 14 is located above the blade 13 , and the cleaning brush 15 is located below the blade 13 .

[0027] like Figure 2 As shown, a collecting box 17 is arranged below the annular tool holder 6 .

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field.

[0029] When in use, first place the pipe to be cut (labeled a in the figure) on the cutting table 1, then fix it by the fixing frame 4, turn on the first motor 3, drive the screw 2 to rotate, and then drive the pipe to start moving, and stop when it moves to the appropriate position.

[0030] Then, the cylinder 11 is turned on to drive the blade 13 to move to the target cutting position, and then the second motor 9 and the third motor 12 are turned on respectively. The second motor 9 drives the gear 10 to rotate, and then drives the ring gear 7 to rotate, thereby driving the knife seat 8 to slide freely on the annular knife holder 6, and the third motor 12 drives the blade 13 to rotate to cut the pipe. The blade 13 cuts around the pipe once to completely cut the pipe.

[0031] The waste chips generated during the cutting process are shielded by a shielding cover 14 to prevent the waste chips from splashing and accidentally injuring workers.
