Therefore, in recent years, some companies have begun to use laser cutting technology with high processing accuracy to improve door and window processing equipment.

[0003] In laser processing equipment, auxiliary gas plays an important role, including enhancing cutting effect, removing slag, cooling, protecting optical components, preventing oxidation and improving cutting quality. A laser generally contains two nozzles, one passes through the inside of the laser and follows the laser, and the other is used to cool the processing object outside.

The inlet pipe 14 transports the auxiliary gas used for cooling to the interior of the cooling part 24, and an inlet joint 22 is fixedly connected to the outer wall of the launch part 25, and the inlet joint 22 is connected to the inlet pipe 13. The auxiliary gas transported at the inlet joint 22 enters into the interior of the launch part 25, and is emitted together with the laser through the straightening channel 31. The gas blown out can be used to protect the internal focusing lens from being affected by debris.

[0023] The outer walls of the inlet pipe 13 and the cooling pipe 14 are both provided with a solenoid valve 11. By setting the solenoid valve 11, the connection and blockage of the cooling pipe 13 and the inlet pipe 14 can be adjusted. The bottom of the solenoid valve 11 is fixedly connected with a fixing part 4, and the fixing part 4 is fixedly connected to the top of the support frame 3. The fixing part 4 is used to fix the cooling pipe 13 and the inlet pipe 14 to prevent them from being entangled together or folded and overlapped by the traction of the moving mechanism, thereby obstructing the airway and interfering with the air supply. The outer wall of the inlet pipe 13 is provided with a detection meter 12. The detection meter 12 is used to detect the air supply situation inside the cooling pipe 13 in real time. Since the detection meter 12 is in the working area, it is convenient for the operators at the processing site to understand the auxiliary gas delivery situation in time. A vertical plate 15 is provided on one side of the fixing part 4, and the vertical plate 15 is fixedly connected to the top of the support frame 3. Two pipe clamps 16 are fixedly connected to the bottom of the inner wall of the vertical plate 15, and the two pipe clamps 16 are respectively sleeved to the outside of the inlet pipe 13 and the cooling pipe 14. The pipe clamp 16 is used to guide and fix the cooling pipe 13 and the inlet pipe 14 .

[0024] A fixing ring 37 is fixedly connected to the interior of the cooling portion 24, and evenly distributed shielding holes 40 are provided on the outer wall of the fixing ring 37. A closing disk 39 is fixedly connected to the bottom of the fixing ring 37. The closing disk 39 seals the internal space of the cooling portion 24. Evenly distributed cooling holes 29 are provided on the bottom of the closing disk 39. A rotating ring 34 is sleeved and rotatably connected to the outside of the fixing ring 37. A gear ring 35 is fixedly connected to the top of the rotating ring 34. Evenly distributed cooling holes 36 are provided on the outer wall of the rotating ring 34, and the cooling holes 36 correspond to the shielding holes 40. 37 blocks 36, so that the auxiliary gas entering from 14 cannot enter. Evenly distributed connecting holes 30 are provided at the bottom of the rotating ring 34, and 30 corresponds to 29. The auxiliary gas entering from 14 is discharged from here. A micro motor 32 is fixedly connected to the outer wall of the focusing portion 21, and a gear 33 is fixedly connected to the output end of the micro motor 32 through a shaft, and the gear 33 and the gear The gear ring 35 is meshed with each other. When the micro motor 32 is started, the driving gear 33 rotates. Through the meshing relationship between the two, the corresponding driving gear ring 35 rotates, and the gear ring 35 then drives the rotating ring 34 to rotate on the fixed ring 37, and accordingly the connecting hole 30 and the cooling hole 36 rotate, and their positions change, thereby changing the matching relationship between them and the cooling hole 29 and the shielding hole 40, that is, the connecting hole 30 no longer exposes the cooling hole 29, so that the airway is blocked, and the shielding hole 40 corresponds to the cooling hole 36, so that the airway is connected, and the auxiliary gas at the inlet pipe 14 enters the interior of the launch part 25 through the cooling part 24, and replaces the cooling pipe 13 to perform auxiliary work. The bottom of the cooling part 24 is fixedly connected with a plurality of connecting pipes 28, and the other end of the connecting pipe 28 is fixedly connected with a nozzle 27, and the nozzle 27 is fixedly connected to the outer wall of the launch part 25 through a rotating shaft. Through this design, the direction and position of the nozzle 27 can be adjusted to change the cooling position.

[0025] The auxiliary gas is respectively input into the interior of the cooling tube 13 and the inlet tube 14 through the external gas supply system, and enters into the interior of the launcher 25 and the cooling section 24 through the inlet joint 22 and the cooling joint 23 respectively. The auxiliary gas used to enter the interior of the launcher 25 follows the laser and mixes from the straightening channel 31 inside the launcher 25, and is ejected through the launch head 26, while the gas entering the interior of the cooling section 24 hovers therein. Under normal circumstances, the rotating ring 34 blocks the shielding hole 40, and the cooling hole 29 is exposed to the interior of the connecting hole 30. Therefore, the auxiliary gas inside the cooling section 24 enters into the interior of the connecting tube 28 from the cooling hole 29, and is ejected through the nozzle 27 to cool the cut area. If a fault occurs, the solenoid valve 11 at the cooling tube 13 closes automatically. At this time, the micro motor 32 is energized and executes a predetermined program to drive the gear 33 to rotate. The gear 33 The gear ring 35 and the rotating ring 34 are driven to rotate synchronously. At this time, affected by the rotation of the rotating ring 34, the hole alignment under normal circumstances changes, the connecting hole 30 gradually covers the cooling hole 29, and the bottom of the rotating ring 34 blocks it, thereby closing the cooling hole 29, and the cooling hole 36 gradually overlaps with the blocking hole 40, and gradually forms a through hole. At this time, the auxiliary gas enters the interior of the launch part 25 from the blocking hole 40, thereby ensuring that the interior of the launch part 25 continues to maintain a state of auxiliary gas, protecting the internal focusing lens and improving the cutting effect. By setting the cooling part 24, the auxiliary gas entering from the cooling pipe 13 hovers in the interior of the cooling part 24, and enters the interior of the nozzle 27 through the connecting pipe 28. Through this design, multiple nozzles 27 can be set to receive the auxiliary gas from the cooling part 24, so that the airflow blown out can cover a larger area and can cool a larger area.

[0026] The outer walls of the inlet pipe 13 and the cooling pipe 14 are jointly covered with a restraining sleeve 17. The restraining sleeve 17 can enhance the protective performance of the cooling pipe 13 and the inlet pipe 14 and play a protective role.

[0027] The diameter of the connecting hole 30 is greater than the diameter of the cooling hole 29 . With this design, the connecting hole 30 is easier to connect with the cooling hole 29 .

[0028] A plurality of pressure relief holes 38 are provided on the outer wall of the closing disk 39. When the connecting hole 30 no longer exposes the cooling hole 29, the inlet pipe 14 is still continuously delivering auxiliary gas to the interior of the cooling portion 24. Through this design, when the connecting hole 30 rotates, the pressure relief holes 38 will be exposed, and the auxiliary gas will be depressurized to the outside of the cooling portion 24 through the pressure relief holes 38, thereby preventing the internal pressure of the cooling portion 24 from rising rapidly and damaging the structure.

[0029] Working principle: Before using, the user first checks whether the device is damaged. After confirming that the device is not damaged, the user places the door and window materials to be cut on the cutting platform 1 in advance, and then adjusts the fixing mechanism 2 to clamp and fix it. After confirming that the fixation is completed, the user starts the device through the controller, and adjusts the position of the laser 10 through the cooperation of the first moving mechanism 5, the second moving mechanism 7 and the third moving mechanism 9, and then cuts and punches the door and window materials clamped and fixed by the fixing mechanism 2; The auxiliary gas delivery process is that the auxiliary gas is respectively input into the interior of the cooling pipe 13 and the inlet pipe 14 through the external gas supply system, and enters into the interior of the launcher 25 and the cooling part 24 through the inlet joint 22 and the cooling joint 23 respectively, wherein the auxiliary gas used to enter the interior of the launcher 25 follows the laser to mix from the straightening channel 31 inside the launcher 25, and is ejected through the launch head 26, while the gas entering the interior of the cooling part 24 hovers therein. At this time, under normal circumstances, the rotating ring 34 blocks the shielding hole 40, and the cooling hole 29 is exposed to the interior of the connecting hole 30, so the auxiliary gas inside the cooling part 24 enters into the interior of the connecting pipe 28 from the cooling hole 29, and is then ejected through the nozzle 27 to perform cutting on the area to be cut. Cooling is performed. If a fault occurs, the solenoid valve 11 at the cooling pipe 13 closes automatically. At this time, the micromotor 32 is energized and executes a predetermined program to drive the gear 33 to rotate. The gear 33 drives the gear ring 35 and the rotating ring 34 to rotate synchronously. At this time, affected by the rotation of the rotating ring 34, the hole alignment under normal circumstances changes, the connecting hole 30 gradually covers the cooling hole 29, and the bottom of the rotating ring 34 blocks it, thereby closing the cooling hole 29, and the cooling hole 36 gradually overlaps with the blocking hole 40, and gradually forms a penetration. At this time, the auxiliary gas enters the interior of the launch part 25 from the blocking hole 40, thereby ensuring that the interior of the launch part 25 continues to be in a state of auxiliary gas, protecting the internal focusing lens and improving the cutting effect.
