[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A steel structure profile cutting tool includes a tool holder 1 and a blade 2. The tool holder 1 is provided with a mounting and fixing assembly 3 that works with the blade 2. The top right side of the tool holder 1 is provided with a cooling assembly 4 that works with the blade 2.

[0027] The mounting and fixing assembly 3 includes a rotating shaft 301, which is rotatably connected to the bottom of the tool holder 1 via a bearing. The right side of the rotating shaft 301 extends to the right side of the blade 2. A positioning plate 302 is fixedly connected to the surface of the rotating shaft 301. The right side of the positioning plate 302 is tightly fitted to the left side of the blade 2. Multiple positioning pins 303 are fixedly connected around the right side of the positioning plate 302. The right side of the positioning pins 303 extends to the right side of the blade 2. A threaded groove 304 is provided on the right side of the surface of the rotating shaft 301. A locking nut 305 is threadedly connected to the right side of the surface of the rotating shaft 301. The left side of the locking nut 305 is tightly fitted to the right side of the blade 2.

[0028] In this embodiment: by setting up a tool holder 1, a blade 2, a mounting and fixing component 3, and a cooling component 4, the tool holder 1 provides a supporting foundation for the mounting and fixing component 3 and the cooling component 4 during use. The mounting and fixing component 3 can stably install and fix the blade 2, and the disassembly and assembly operations are relatively convenient when replacing the blade 2 later, without the need to remove and install a large number of bolts, which brings convenience to the operator. The cooling component 4 can assist in cooling the blade 2 when cutting steel structure profiles, thereby effectively improving the service life and cutting performance of the blade 2.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the cooling component 4 includes a vortex tube 401, an air inlet connector 402 connected to the right side of the vortex tube 401, a hot air exhaust pipe 403 connected to the rear side of the vortex tube 401, and a cold air exhaust pipe 404 connected to the front side of the vortex tube 401.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a diversion pipe 405 is connected to the front side of the air conditioning pipe 404. Both ends of the diversion pipe 405 are connected to a universal adjusting bellows 406. The other end of the universal adjusting bellows 406 is connected to an air conditioning nozzle 407.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a fixing block 408 is fixedly connected to the left side of the vortex tube 401, and the fixing block 408 is fixedly connected to the tool holder 1 on the side near the tool holder 1.

[0032] In this embodiment: by setting up a vortex tube 401, an air inlet connector 402, a hot air pipe 403, a cold air pipe 404, a splitter pipe 405, a universal adjustable bellows 406, a cold air nozzle 407, and a fixing block 408, during the cutting operation, firstly, the two cold air nozzles 407 are adjusted to a suitable position and spray angle through the two universal adjustable bellows 406, and then compressed air is introduced through the air inlet connector 402 of the vortex tube 401. The compressed air will rotate at high speed inside the vortex tube 401, separating the low-temperature airflow and the high-temperature airflow. The airflow consists of two parts: a high-temperature airflow that is discharged through the hot air exhaust pipe 403 and a low-temperature airflow that enters the diversion pipe 405 through the cold air exhaust pipe 404, and then enters the two universal adjustable bellows 406 through the diversion pipe 405. Finally, the two cold air nozzles 407 spray the low-temperature airflow onto the cutting area of ​​the blade 2, which can quickly remove the cutting heat and thus achieve the effect of auxiliary cooling of the blade 2, effectively improving the service life and cutting performance of the blade 2. The vortex tube 401 can be supported and fixed by the setting of the fixing block 408.

[0033] Specifically, such as Figure 5 As shown, the left side of the blade 2 has a through-hole 5 that works with the rotating shaft 301, and the surface of the rotating shaft 301 contacts the inner wall of the through-hole 5.

[0034] Specifically, such as Figure 5 As shown, the blade 2 has through holes 6 around its left side for use with positioning pins 303, and the surface of positioning pins 303 is in contact with the inner wall of the through holes 6.

[0035] In this embodiment: by providing a through-hole 5, the blade 2 can be fitted onto the surface of the rotating shaft 301; by providing a through hole 6, the positioning pin 303 can pass through the blade 2 and position the blade 2.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, a mounting plate 7 is fixedly connected to the left side of the rotating shaft 301, and multiple first mounting holes 8 are opened around the right side of the mounting plate 7.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, a mounting plate 9 is fixedly connected to the top of the tool holder 1, and a second mounting hole 10 is provided at each of the four corners of the top of the mounting plate 9.

[0038] In this embodiment: by setting the mounting plate 7 and the first mounting hole 8, the rotating shaft 301 can be installed and fixed to the drive shaft of the cutting equipment using bolts; by setting the mounting plate 9 and the second mounting hole 10, the tool holder 1 can be installed and fixed to the support structure of the cutting equipment using bolts.

[0039] Working Principle: In use, firstly, the rotating shaft 301 is installed and fixed to the drive shaft of the cutting equipment using bolts through the mounting plate 7 and the first mounting hole 8. Then, the blade holder 1 is installed and fixed to the support structure of the cutting equipment using bolts through the mounting plate 9 and the second mounting hole 10. Next, the blade 2 is threaded through the through-hole 5 onto the surface of the rotating shaft 301 and moved until it is flush with the positioning plate 302. Simultaneously, multiple positioning pins 303 are inserted into the multiple through holes 6 of the blade 2. The positioning plate 302 and positioning pins 303 provide initial positioning of the blade 2. Then, the locking nut 305 is placed on the rotating shaft 301 and tightened. The locking nut 305 moves under the action of the threads, securing the blade 2. This completes the installation of the blade 2. For later replacement of the blade 2, the operation is reversed for easy disassembly, eliminating the need to remove numerous bolts and providing convenience for operators. Then, the drive shaft of the cutting equipment can drive the rotating shaft 301 to rotate. The rotating shaft 301 will drive the blade 2, which is in the positioning and locking state, to rotate. The rotation of the blade 2 can cut the steel structure profile. During the cutting operation, the two cold air nozzles 407 can be adjusted to the appropriate position and spray angle through the two universal adjustable bellows 406. Then, compressed air is introduced into the air inlet 402 of the vortex tube 401. The compressed air will rotate at high speed in the vortex tube 401 to separate the low temperature airflow and the high temperature airflow. The high temperature airflow will be discharged through the hot air exhaust pipe 403, and the low temperature airflow will enter the diversion pipe 405 from the cold air exhaust pipe 404. Then, it will enter the two universal adjustable bellows 406 through the diversion pipe 405. Finally, the two cold air nozzles 407 will spray the low temperature airflow onto the cutting area of ​​the blade 2, which can quickly remove the cutting heat, thereby achieving the effect of auxiliary cooling of the blade 2, effectively improving the service life and cutting performance of the blade 2.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
