[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] To solve the technical problem of how a cutting machine cuts metal pipes, please refer to Figures 1 - 3 , the following technical solutions are provided in this embodiment:

[0023] A cutting machine for metal pipes that is convenient for cleaning debris, including a machine body 1. The machine body 1 is divided into an upper and a lower collection chamber 14 and a cutting chamber 13. A cylinder 131 is installed in the cutting chamber 13. The output end of the cylinder 131 is connected to a dust suction box 132. The lower end of the dust suction box 132 is installed with a second motor 1322 through a fixed frame 1321. The output end of the second motor 1322 is fixedly connected to a cutting head 1323.

[0024] The lower end of the machine body 1 is welded with a bottom plate 11. Fixed plates 12 are symmetrically arranged at the front and rear ends of the machine body 1. A pipe sleeve 121 is movably installed on the fixed plates 12. One end of the pipe sleeve 121 is fixedly connected to a toothed ring 1211. A rotating shaft 122 is movably installed between the fixed plates 12. A gear 1221 meshing with the toothed ring 1211 is provided on the rotating shaft 122. One end of the rotating shaft 122 is fixedly connected to a first motor 1222.

[0025] Among them, both ends of the dust suction box 132 are slidably connected to the inner wall of the cutting chamber 13. Through holes for inserting metal pipes are opened at the front and rear ends of the cutting chamber 13, and an observation port is opened at the side end of the cutting chamber 13.

[0026] Specifically, both ends of the metal pipe are clamped with the pipe sleeve 121, and the part to be cut is aligned with the cutting head 1323. Then, the second motor 1322 is started. The second motor 1322 drives the cutting head 1323 to rotate. Then, the cylinder 131 is started. The cylinder 131 drives the cutting head 1323 to descend through the dust suction box 132 until the cutting head 1323 is inserted into the metal pipe. Then, the first motor 1222 is started. The first motor 1222 drives the gear 1221 to rotate through the rotating shaft 122. The gear 1221 drives the toothed ring 1211 meshing with it to rotate. The toothed ring 1211 drives the pipe sleeve 121 fixedly connected to it to rotate. The pipe sleeve 121 drives the metal pipe clamped with it to rotate, so that the cutting head 1323 can cut along the pipe wall of the metal pipe until the metal pipe is cut off.

[0027] To solve the technical problem of how the cutting machine collects debris, please refer to Figure 2, this embodiment provides the following technical solutions:

[0028] An air pump 16 is installed on the outer wall of the machine body 1. One end of the air pump 16 is hermetically connected to the dust suction box 132 through a dust suction pipe 15. The other end of the air pump 16 is hermetically connected to a dust outlet pipe 17. A dust suction nozzle 1324 is installed at the lower end of the dust suction box 132. The dust suction nozzle 1324 is located on the left and right sides of the cutting head 1323.

[0029] An air outlet 141 is opened at the top of the collection chamber 14. A first filter screen 142 and a second filter screen 143 are installed up and down in the collection chamber 14. The end of the dust outlet pipe 17 is arranged at the lower end of the second filter screen 143. A drawer 144 is slidably connected to the bottom of the collection chamber 14.

[0030] Among them, the drawer 144 is provided to facilitate the regular cleaning of the collected debris.

[0031] Specifically, when the cutting head 1323 performs cutting, debris will splash around it. The debris is sucked into the dust suction box 132 by the dust suction nozzle 1324, then enters the dust suction pipe 15 from the dust suction box 132, and finally is introduced into the collection chamber 14 through the dust outlet pipe 17. Since the end of the dust outlet pipe 17 is located at the lower end of the second filter screen 143, the debris in the air will directly fall into the drawer 144, while the air passes through the first filter screen 142 and the second filter screen 143 and is discharged from the air outlet 141. Through the filtration of the first filter screen 142 and the second filter screen 143, the dust particles in the air can be effectively removed, preventing the secondary raising of dust.

[0032] Working principle: For this metal pipe cutting machine that is convenient for cleaning debris, when in use, first fix the metal pipe so that its two ends are engaged with the pipe sleeve 121, and align the part to be cut with the cutting head 1323. Then start the second motor 1322 to drive the cutting head 1323 to rotate. Next, start the cylinder 131, and the cylinder 131 drives the cutting head 1323 to move downward until the cutting head 1323 is inserted into the metal pipe. Then start the first motor 1222. The first motor 1222 drives the gear 1221 to rotate through the rotating shaft 122. The gear 1221 then drives the toothed ring 1211 meshing with it to rotate. The toothed ring 1211 then drives the pipe sleeve 121 fixedly connected to it to rotate. The pipe sleeve 121 drives the metal pipe engaged with it to rotate, so that the cutting head 1323 can cut along the wall of the metal pipe until the cutting is completed. The debris generated during cutting will be adsorbed by the dust suction nozzle 1324 and introduced into the collection chamber 14. The debris falls into the drawer 144, while the air passes through the filtration of the first filter screen 142 and the second filter screen 143, effectively removing the dust particles mixed inside, preventing the dust from filling the production workshop, and improving the working environment.
