[0033] Figure 1 For a schematic structural diagram of the slag removal device in an embodiment.

[0034] In the present embodiment, as shown in Figure 1 The slag removal device is used for removing the slag on the surface of the workpiece during the combined piercing process of the laser-flame combined cutting machine. The slag removal device comprises an air inlet pipeline 10, a pressure regulating unit 20, a shunt slag removal pipeline 30, a cutting head mounting part 40, a pipeline mounting part 50, and a supporting part 60. The workpiece can be a workpiece plate or the like.

[0035] The pressure regulating unit 20 is arranged on the air inlet pipeline 10. One end of the air inlet pipeline 10 is connected to an external air source. The opposite end of the air inlet pipeline 10 is connected to one end of the pressure regulating unit 20. The opposite end of the pressure regulating unit 20 is connected to the air inlet end of the shunt slag removal pipeline 30. The air outlet end of the shunt slag removal pipeline 30 is located outside the cutting head.

[0036] The air inlet pipeline 10 can be a pipeline arranged between the external air source and the pressure regulating unit 20, which can receive the gas output by the external air source and transmit the gas to the pressure regulating unit 20. The pressure regulating unit 20 can be a functional unit arranged between the air inlet pipeline 10 and the shunt slag removal pipeline 30, which can receive the gas input via the air inlet pipeline 10, adjust the pressure of the gas, and output the gas with adjusted pressure to the shunt slag removal pipeline 30. The shunt slag removal pipeline 30 can be a pipeline connected to the pressure regulating unit 20 and close to the cutting head, which can receive the gas output via the pressure regulating unit 20 and output the gas towards the cutting head for slag removal. Optionally, the air inlet pipeline 10 can be a hollow circular tube. The shunt slag removal pipeline 30 can be a hollow circular tube with a shunt structure.

[0037] The cutting head mounting part 40 is connected to the air outlet end of the shunt slag removal pipeline 30 and the laser, which can drive the air outlet end of the shunt slag removal pipeline 30 to move with the laser. The pipeline mounting part 50 is connected to the cutting head mounting part 40. The supporting part 60 is connected to the pipeline mounting part 50 and the air outlet end of the shunt slag removal pipeline 30.

[0038] The cutting head mounting part 40 can be a functional part connected to the cutting head and the pipeline mounting part 50, which can drive the pipeline mounting part 50 to move synchronously with the cutting head. The pipeline mounting part 50 can be a functional component connected to the cutting head mounting part 40 and the shunt slag removal pipeline 30, which can provide support and bearing for the shunt slag removal pipeline 30. The supporting part 60 can be a functional part connected to the shunt slag removal pipeline 30, which can limit the shunt slag removal pipeline 30. Optionally, the cutting head mounting part 40 can be a cutting head mounting plate, a mounting block, or a mounting bracket, etc. The pipeline mounting part 50 can be a pipeline mounting seat or a mounting block, etc. The supporting part 60 can be a supporting rod, a supporting strip, or a supporting bracket, etc.

[0039] The diversion and slag removal pipe 30 includes a diversion sub-pipe 310 and a slag removal sub-pipe 320. One end of the diversion sub-pipe 310 is connected to the opposite end of the pressure regulating unit 20, and the opposite end of the diversion sub-pipe 310 is connected to one end of the slag removal sub-pipe 320. The opposite end of the slag removal pipe 320 is located outside the cutting nozzle of the cutting head.

[0040] The diversion sub-pipe 310 can be connected to the pressure regulating unit 20 and the slag removal sub-pipe 320, and can receive the pressure-adjusted gas output from the pressure regulating unit 20 and divert the gas to the slag removal sub-pipe 320. The slag removal sub-pipe 320 can be connected to the diversion sub-pipe 310 and close to the cutting head, and can receive the gas output from the diversion sub-pipe 310 and output the gas toward the cutting head for slag removal.

[0041] The slag removal pipe 320 has a corner air outlet section on the side near the cutting nozzle of the cutting head, and the output end of the corner air outlet section is aligned at a preset angle directly below the cutting nozzle of the cutting head. Optionally, the output end of the corner air outlet section is made of metal. The slag removal pipe 320 can be a hollow copper round pipe.

[0042] The corner air outlet section can be a functional structure located at the bottom of the slag removal sub-pipe 320 along the height direction of the cutting head, capable of blowing air at a preset angle directly below the cutting nozzle of the cutting head to blow the molten slag located directly below the cutting head away from the surface of the processed part. Optionally, the corner air outlet section can be a hollow copper round tube with a certain corner.

[0043] During the composite processing, laser and flame simultaneously act on the perforated residue on the surface of the processed part, and heat it by moving along each motion axis according to the set slag removal trajectory, so that the slag is in a high-temperature molten state. An external gas source enters the gas inlet pipe 10 through one end of the gas inlet pipe 10, and then enters the pressure regulating unit 20 through the opposite end of the gas inlet pipe 10. Under the action of the pressure regulating unit 20, the pressure of the inflowing gas is regulated. The pressure-regulated gas then enters the inlet end of the diversion slag removal pipe 30 through one end of the pressure regulating unit 20, and then is released towards the cutting head through the outlet end of the diversion slag removal pipe 30. That is, the gas blown out through the outlet end of the diversion slag removal pipe 30 is aimed at a certain position directly below the cutting nozzle, so that the molten slag located directly below the cutting nozzle of the cutting head is blown away from the surface of the processed part during slag removal.

[0044] like Figure 2 As shown, the support component 60 includes a first limiting member 610, a second limiting member 620, and a connecting member 630. The first limiting member 610 is provided with a first inner arc surface, the second limiting member 620 is provided with a second inner arc surface, and the connecting member 630 can limit the air outlet end of the diversion and slag removal pipe 30 between the first inner arc surface and the second inner arc surface.

[0045] The first limiting member 610 can be arranged on one side of the support member 60 close to the cutting head mounting member 40, and can be a functional member capable of adhering to one side of the outer surface of the slag removal sub-pipe 320 and being positionally constrained. The second limiting member 620 can be arranged on one side of the support member 60 away from the cutting head mounting member 40, and can be a functional member capable of adhering to the outer surface of the opposite side of the slag removal sub-pipe 320 and being positionally constrained. The connecting member 630 can be a connecting structure connected to the first limiting member 610 and the second limiting member 620, and can be a fixing member capable of closely adhering the first limiting member 610 and the second limiting member 620 to the outer surface of the slag removal sub-pipe 320. Alternatively, the first limiting member 610 and the second limiting member 620 can each be a limiting block or a limiting seat with an inner arc surface. The connecting member 630 can be a connecting structure including a bolt and a nut.

[0046] When the gas outlet ends of the plurality of shunt slag removal pipes 30 are spaced apart on the outside of the cutting head, and when the gas outlet ends of the two shunt slag removal pipes 30 are arranged opposite to each other on the outside of the cutting head, the number of shunt slag removal pipes 30 can be increased by spacing apart the outside of the cutting head, so that the gas blown from different directions on the outside of the cutting head can be directed to the exact position below the cutting nozzle of the cutting head, effectively increasing the total amount of gas blown to the exact position below the cutting nozzle of the cutting head per unit time, and further improving the slag removal efficiency while improving the uniformity of slag removal during the composite piercing process.

[0047] During the composite machining process, the laser and the flame act on the piercing slag on the surface of the machined part at the same time, and the slag is heated by moving along the set slag removal trajectory by each movement axis, so that the molten slag is in a high-temperature molten state. The high-pressure gas blown out of the gas outlet end of the shunt slag removal pipe 30 is directed to the surface of the machined part below the cutting nozzle of the cutting head, so that the molten slag below the cutting nozzle of the cutting head is blown away from the surface of the machined part during slag removal. When the height of the cutting head changes, the shunt slag removal pipe 30 is connected to the cutting head mounting member 40 under the cooperation of the cutting head mounting member 40 (such as a cutting head mounting plate), the pipe mounting member 50 (such as a pipe mounting seat), and the support member 60 (such as a support rod), so that the shunt slag removal pipe 30 can move synchronously with the cutting head to maintain the relative positional relationship between the two, and the high-pressure gas blown out of the gas outlet end of the shunt slag removal pipe 30 is directed to the surface of the machined part below the cutting nozzle of the cutting head, so that the molten slag in a molten state is separated from the surface of the machined part and finally blown away from the surface of the machined part.

[0048] During the composite piercing process, as shown in FIG. 6, the laser and the flame act on the piercing slag on the surface of the machined part at the same time, and the slag is heated by moving along the set slag removal trajectory by each movement axis, so that the molten slag is in a high-temperature molten state. The high-pressure gas blown out of the gas outlet end of the shunt slag removal pipe 30 is directed to the surface of the machined part below the cutting nozzle of the cutting head, so that the molten slag below the cutting nozzle of the cutting head is blown away from the surface of the machined part during slag removal. Figure 3As shown, the slag removal trajectory is generally an equidistant spiral, and point O is both the starting point and the ending point of the spiral slag removal trajectory, and is also the piercing point, the starting radius R1 of the spiral slag removal trajectory is in the range of 1-10mm, and is generally slightly smaller than the size of the piercing hole, the thicker the processed part, the larger the piercing hole, and the larger the starting radius R1 of the spiral slag removal trajectory; the range radius R2 of the spiral slag removal trajectory is generally 0.1T-0.2T (T is the thickness of the processed part), and can be adjusted according to the actual slag removal effect, and the range radius R2 of the spiral slag removal trajectory is too small, the slag removal effect is poor, and too large increases the slag removal time; the rotation radius R3 of the spiral slag removal trajectory is generally half of R2, so that the cutting head returns to the starting point O of the spiral slag removal trajectory; the spacing D of the spiral slag removal trajectory is in the range of 2-5mm, and can be adjusted according to the actual slag removal effect, and the spacing D of the spiral slag removal trajectory is too large, the slag removal effect is poor, and too small, the heat is too concentrated, and the surface of the processed part is easy to ablate.

[0049] The application also provides a processing equipment, which comprises the slag removal device and the laser in the above-mentioned embodiments, and the laser is connected to the slag removal device, and the processing equipment can be a laser-flame composite cutting machine.

[0051] The slag removal device and the processing equipment provided in the above-mentioned embodiments can realize that the molten slag near the cutting head in the composite piercing process is blown away from the surface of the processed part under the action of the external gas source, effectively improve the problem that a lot of time is spent in the slag removal process when the artificial slag removal method is used, so as to improve the slag removal effect in the composite piercing process, also ensure the efficiency of the slag removal process, meet the slag removal demand of the laser in the laser processing process, further meet the higher requirements of the laser processing process, and have important economic value and popularization and practice value.
