Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of water spraying slag removal, and in particular, to a water spraying slag removal mechanism and method for a laser tube cutting machine. Background Art

[0002] Laser tube cutting machine is a prior art equipment used to cut tubes to a fixed length. It uses a high-energy-density laser beam to heat the corresponding area of the tube, causing the surface of the tube to melt and vaporize, and then cut the tube. When the laser beam contacts the tube, molten residue will appear on the surface of the tube. During the cutting process, these residues will sputter. Therefore, in laser tube cutting machines, a slag removal mechanism is generally adopted to process the sputtered residue to prevent the residue from sputtering at will.

[0003] In the prior art, there are two methods for processing the residue generated during the operation of the laser tube cutting machine: gas slag removal and water slag removal. During the use of the gas slag removal mechanism and the water slag removal mechanism, the gas slag removal mechanism uses airflow to blow the sputtered residue and blow the residue to the corresponding material connection position. When cutting some pipes with more serious residue generated during the cutting process, the water slag removal mechanism is used to spray atomized water flow, so that the residue contacts the atomized water flow and the atomized water flow carries the residue down. Through the above method, the slag removal function in the laser tube cutting process is achieved. During the use of the water slag removal method, because the distance increases and the falling speed of the atomized water flow is slow, it is necessary to make the distance between the output end of the atomized water flow and the cutting area of the pipe closer. When cutting pipes of different diameters, due to the difference in pipe diameters, the distance between the output end of the atomized water flow and the pipe is difficult to adjust, resulting in the problem that the distance between the atomized water flow and the processed pipe is not convenient for effectively removing the residue. Summary of the Invention

[0004] In order to overcome the above-mentioned defects, an embodiment of the present invention provides a water spraying and slag removal mechanism and method for a laser tube cutting machine, which is used to solve the technical problem that during the use of the water spraying and slag removal mechanism on the laser tube cutting machine in the related technology, when laser cutting pipes of different diameters, there is a difference in the distance between the atomized water flow and the pipe.

[0005] The present invention provides a water spraying and slag removal mechanism for a laser tube cutting machine, comprising a plurality of atomizing nozzles and further comprising:

[0006] The mounting bracket is arranged inside the laser tube cutting machine, and a water delivery pipe is movably arranged on both sides of the mounting bracket. The upper and lower sides of the water delivery pipe are respectively provided with a contraction and expansion movable pipe section and a longitudinal movable pipe section. The upper side of the contraction and expansion movable pipe section is connected to a plurality of the atomizing nozzles, and the contraction and expansion movable pipe section is provided with an arc-shaped material receiving trough for receiving residues;

[0007] There are multiple movable plates, each of which is provided with a retractable and expandable movable assembly. The multiple movable plates are respectively fixedly connected to corresponding positions of the two retractable and expandable movable pipe sections, and are used to expand the two retractable and expandable movable assemblies to corresponding circumferential areas to accommodate pipes of different diameters.

[0008] Airflow slag blowing components are provided on both sides of the top of the mounting bracket, and are used to blow the residue after moisture absorption into the arc-shaped material receiving trough;

[0009] A tension connection mechanism is provided between the longitudinally movable pipe section and the bottom of the mounting bracket, and is used to accommodate the longitudinal movement of the longitudinally movable pipe section within the mounting bracket.

[0010] In order to limit the movement of the water delivery pipe, the mounting bracket further includes a C-shaped frame and an arc-shaped protective trough frame. The C-shaped frame is arranged inside the laser tube cutting machine. The middle part of the C-shaped frame is fixedly connected to a sliding trough frame. Both sides of the C-shaped frame are slidably connected to the sliding trough frame with sliding plates. The longitudinal movable pipe section is located in the C-shaped frame. The bottom of the longitudinal movable pipe section passes through the sliding plate. Both sides of the top of the C-shaped frame are fixedly connected to the arc-shaped protective trough frame. The expansion and retraction movable pipe section is located in the arc-shaped protective trough frame. A vertical section is provided on the top of the arc-shaped protective trough frame. The top of the expansion and retraction movable pipe section is fixedly connected to the vertical section.

[0011] In order to drive the expansion and contraction of the movable pipe section, the expansion and contraction movable component further includes a circular frame and a movable seat. The circular frame is arranged in the laser pipe cutting machine. An annular threaded disk is rotatably connected in the circular frame. A driving component is arranged between the annular threaded disk and the circular frame. Multiple movable plates are slidably arranged in the circular frame through the movable seat, and the movable seat is threadedly connected to the annular threaded disk.

[0012] In order to keep the position of the arc-shaped material receiving trough body fixed, the top of the arc-shaped material receiving trough body is fixedly connected to the expanding and retracting movable pipe section, the outer arc surface of the arc-shaped material receiving trough body is set to a narrow groove shape, and the outer wall of the outer arc surface of the arc-shaped material receiving trough body is provided with an abutment groove adapted to the expanding and retracting movable pipe section.

[0013] In order to collect the water flow and residue, further, the bottom of the arc-shaped material receiving trough body is connected to a collection bag, and the bottom of the collection bag is connected to a discharge valve pipe.

[0014] The urn of described outer wall of described outer wall is provided with the water-clearing nozzle that is provided with at least one nozzle and is connected with the water-clearing nozzle of described outer wall to be connected with the water-clearing nozzle.

[0015] In order to blow the atomized water and residue downward after they come into contact, the air flow slag blowing assembly further includes an air injection cylinder and an air supply pipeline. The two vertical sections are fixedly connected to the air injection cylinder, and the bottom end of the air injection cylinder is connected to a curved conveying pipeline. The bottom of the curved conveying pipeline is connected to multiple air blowing pipes of the same size. The multiple air blowing pipes are arranged in a stepped manner at the bottom of the curved conveying pipeline to speed up the speed at which the residue falls into the arc-shaped material receiving trough body, and to prevent the atomized water from contacting the working end of the laser pipe cutting machine. The air supply pipeline is connected between the tops of the two air injection cylinders.

[0016] In order to adapt to the longitudinal movement of the longitudinally movable pipe section in the mounting bracket, the tension connection mechanism further includes a fixed water pipe and a spring damper. The fixed water pipes are connected on both sides of the bottom of the U-shaped frame. A telescopic water pipe is connected between the fixed water pipe and the bottom of the longitudinally movable pipe section. The spring damper is arranged between the sliding plate and the inner bottom wall of the U-shaped frame.

[0017] In order to synchronously add water into the two water delivery pipes, a synchronous water supply component is further provided between the two fixed water pipes.

[0018] A water spraying slag removal method for a laser tube cutting machine comprises the following steps:

[0019] Step 1: Adjusting the position: Before laser cutting the pipe, the driving assembly drives the annular threaded disk to rotate according to the pipe diameter, and adjusts the position of the plurality of movable plates, so that the position of the contraction and expansion movable pipe section changes accordingly, and adjusts the distance between the atomizing nozzle and the pipe;

[0020] Step 2: Water supply: water is delivered to the fixed water pipe through the synchronous water supply component, and then the water enters the delivery water pipe through the telescopic water pipe;

[0021] Step 3: Spraying water to remove slag: During the cutting process, if slag splashing occurs, water is sprayed through the atomizing nozzle to allow the atomized water to fully contact the slag to perform the slag removal operation;

[0022] Step 4: Airflow slag blowing: Gas is injected into the two gas injection cylinders through the air supply pipeline, so that the gas enters the curved conveying pipeline and is finally discharged through the multiple air blowing pipes. The airflow drives the atomized water and the residue to move toward the arc-shaped receiving trough.

[0023] Step 5, discharge the residue: After the residue enters the arc-shaped material receiving trough body, it will flow downward along the inner wall of the arc-shaped material receiving trough body, then flow into the collection bag, and finally be discharged through the discharge valve pipe.

[0024] The beneficial effects of the embodiments of the present invention are:

[0025] 1. In the present invention, during actual use, when the laser tube cutting machine cuts the tube, there will be a problem of residue splashing. In the application process of the present invention, first, when it is necessary to cut tubes of different diameters, the positions of the multiple moving pieces can be adjusted by the expansion and contraction moving assembly, and then the multiple moving pieces begin to adjust the expansion or contraction range of the expansion and contraction moving pipe section, and adjust the spacing between the atomizing nozzle and the tube, so that the atomized water sprayed by the atomizing nozzle can better contact with the splashed residue during the process, and as the expansion and contraction moving pipe section moves, the positions of the multiple atomizing nozzles are adjusted, and the position of the arc-shaped material receiving trough is also adjusted, so that the arc-shaped material receiving trough can be fully moved to the bottom of the tube cutting position, so that the residue caused by the splashing phenomenon when cutting tubes of different diameters can be effectively and thoroughly removed, and the residue is prevented from splashing to different positions inside the laser tube cutting machine.

[0026] 2. In the present invention, during actual use, when the atomized water comes into contact with the residue during the spraying process, the movement speed of the atomized water is slow, and the atomized water may also diffuse inside the laser tube cutting machine. In order to limit the dispersion and discharge of the atomized water, a plurality of air blowing pipes arranged in a stepped manner are used to blow the atomized water toward the arc-shaped material receiving trough body, so that the atomized water mixed with the residue falls into the arc-shaped material receiving trough body as soon as possible, and the air blowing pipe close to the output end of the laser tube cutting machine is also at the bottom between the plurality of air blowing pipes. By blowing gas through the air blowing pipe, the atomized water can be prevented from contacting the working end of the laser tube cutting machine.

[0027] 3. In the present invention, after water and residue enter the arc-shaped material receiving trough body, the residue will adhere to the inner wall of the arc-shaped material receiving trough body. In order to improve the discharge effect of the residue, water is injected into the vertical water outlet pipe and the two wall-cleaning water pipes through the outlet valve pipe. After the water is discharged through the wedge-shaped drain port, it flows along the inner wall of the arc-shaped material receiving trough body and flushes the residue. After the water is discharged in a fan-shaped dispersion through the trapezoidal drain hole, the side wall of the arc-shaped material receiving trough body is cleaned, thereby realizing the cleaning operation of the inner wall of the arc-shaped material receiving trough body.

[0046] Example 1, as Figures 1 to 2 As shown, the present invention discloses a water spraying and slag removal mechanism for a laser tube cutting machine, which is applied to the laser tube cutting machine in the prior art. The laser tube cutting machine in the prior art includes a processing chamber 31 and a power distribution chamber 32. A pipe feeding mechanism 33 is provided on one side of the processing chamber 31, and a pipe jacking mechanism 34 is provided on the other side of the processing chamber 31. The pipe feeding mechanism 33 and the pipe jacking mechanism 34 are both common supporting equipment on the laser tube cutting machine in the prior art, and are used to transport and fix the cut pipes. The working end 35 of the laser tube cutting machine is provided in the processing chamber 31. The processing chamber 31, the power distribution chamber 32, the pipe feeding mechanism 33, the pipe jacking mechanism 34 and the working end 35 of the laser tube cutting machine described above are all existing technical equipment supporting the laser tube cutting machine in the prior art, and are prior art well known to those skilled in the art.

[0047] like Figures 1 to 7As shown, it includes multiple atomizing nozzles 1 and a mounting bracket 2. The mounting bracket 2 is arranged between the processing chamber 31 and the power distribution chamber 32 inside the laser tube cutting machine. A water delivery pipe 3 is movably arranged on both sides of the mounting bracket 2. The upper and lower sides of the water delivery pipe 3 are respectively provided with a retractable and enlarged movable pipe section 4 and a longitudinal movable pipe section 5. The upper side of the retractable and enlarged movable pipe section 4 is connected to multiple atomizing nozzles 1. An arc-shaped material receiving trough 6 for receiving residues is provided on the retractable and enlarged movable pipe section 4. When it is necessary to move multiple atomizing nozzles 1 between the pipe cutting position When the spacing is adjusted, the expansion and contraction movable pipe section 4 can be moved within the range of the arc-shaped protective trough frame 11 to adjust the expansion or contraction area of the expansion and contraction movable pipe section 4. When the expansion and contraction movable pipe section 4 expands or contracts, the position between the multiple atomizing nozzles 1 and the pipe is also adjusted. During the movement of the expansion and contraction movable pipe section 4, the arc-shaped material receiving trough body 6 also adaptively adjusts the corresponding position, so that the position of the arc-shaped material receiving trough body 6 is always located between the multiple atomizing nozzles 1 and the bottom of the multiple blowing pipes 26, effectively collecting moisture and residue.

[0048] like Figures 1 to 7 As shown, the mounting bracket 2 includes a U-shaped frame 8 and an arc-shaped protective groove frame 11. The U-shaped frame 8 is arranged between the processing chamber 31 and the power distribution chamber 32 inside the laser tube cutting machine. The middle part of the U-shaped frame 8 is fixedly connected with a sliding groove frame 9. Both sides of the U-shaped frame 8 are slidably connected with the sliding groove frame 9 by a sliding plate body 10. The longitudinal movable pipe section 5 is located in the U-shaped frame 8. The bottom of the longitudinal movable pipe section 5 passes through the sliding plate body 10. The top two sides of the U-shaped frame 8 are fixedly connected with the arc-shaped protective groove frame 11. The retractable and expandable movable pipe section 4 is located in the arc-shaped protective groove frame 11. 1, a vertical section 12 is provided at the top of the arc-shaped protective trough frame 11, and the top of the expansion and retraction movable pipe section 4 is fixedly connected to the vertical section 12. During the movement of the expansion and retraction movable pipe section 4, the longitudinal movable pipe section 5 moves longitudinally within the U-shaped frame 8, so that the expansion and retraction movable pipe section 4 can be better expanded. During the expansion of the expansion and retraction movable pipe section 4, the expansion and retraction movable pipe section 4 always moves within the inner wall range of the arc-shaped protective trough frame 11, so that the expansion and retraction movable pipe section 4 is fully protected during use, avoiding the problem of collision between the pipe and the expansion and retraction movable pipe section 4.

[0049] like Figures 1 to 3 and Figure 6As shown, the number of movable pieces 7 is set to be multiple, and a contraction and expansion movable assembly is provided between the multiple movable pieces 7. The multiple movable pieces 7 are respectively fixedly connected to the corresponding positions of the two contraction and expansion movable pipe sections 4, and are used to expand the two contraction and expansion movable assemblies to the corresponding circumferential areas to adapt to pipes of different diameters. The contraction and expansion movable assembly includes a circular frame 13 and a movable seat 15. The circular frame 13 is arranged in the laser pipe cutting machine. An annular threaded disk 14 is rotatably connected in the circular frame 13. A driving assembly is provided between the annular threaded disk 14 and the circular frame 13. The multiple movable pieces 7 are all slidably arranged in the circular frame 13 through the moving seat 15. The moving seat 15 is threadedly connected to the annular threaded disk 14. A sliding rod is provided on the moving seat 15. The sliding rod passes through and is slidably connected to the circular frame 13. The driving assembly includes a bevel gear 1 36, a bevel gear 2 37, a rotating shaft 38 and a driving assembly. The driving motor 39 is provided with a bevel gear 1 36 on the side opposite to the moving seat 15, and a bevel gear 2 37 is meshed on the bevel gear 1 36. The top of the circular frame 13 is penetrated by a rotating shaft 38, and the bevel gear 2 37 is fixedly connected to the rotating shaft 38. The circular frame 13 is provided with a driving motor 39, and the output end of the driving motor 39 is fixedly connected to the rotating shaft 38. When it is necessary to make multiple moving pieces 7 move away from or approach each other, the driving motor 39 is started to drive the rotating shaft 38 to rotate, and the annular threaded disk 14 is driven to rotate through the meshing relationship between the bevel gear 1 36 and the bevel gear 2 37, and then the moving seat 15 and the moving piece 7 threadedly connected to the annular threaded disk 14 start to move, and the moving piece 7 is used to drive the expansion and contraction moving pipe section 4 to move to adjust the position of the atomizing nozzle 1 and the arc-shaped material receiving trough 6.

[0050] like Figures 1 to 10 As shown, the top of the arc-shaped material receiving trough body 6 is fixedly connected to the expansion and retracting movable pipe section 4, and the outer arc surface of the arc-shaped material receiving trough body 6 is set to a narrow groove shape, and an abutment groove 16 adapted to the expansion and retracting movable pipe section 4 is opened on the outer wall of the outer arc surface of the arc-shaped material receiving trough body 6, and the arc angle of the arc-shaped material receiving trough body 6 is consistent with the arc angle of the arc-shaped protective trough frame 11. Because only the top of the arc-shaped material receiving trough body 6 is connected to the middle area of the expansion and retracting movable pipe section 4, therefore, when the expansion and retracting movable pipe section 4 is contracted or expanded, the abutment groove 16 opened on the outer arc surface of the arc-shaped material receiving trough body 6 will contact different positions of the expansion and retracting movable pipe section 4, which is convenient for adjusting the position of the arc-shaped material receiving trough body 6, and by setting the outer arc surface of the arc-shaped material receiving trough body 6 to a narrow groove shape, the side of the arc-shaped material receiving trough body 6 close to the outer arc surface is narrower, which is convenient for collecting and discharging collected water and residue;

[0051] The bottom of the arc-shaped material receiving trough body 6 is connected to a collecting bag 17, and the bottom of the collecting bag 17 is connected to a discharge valve pipe 18. As enough water and residue are collected, the water and residue are mixed and flow together to the bottom of the arc-shaped material receiving trough body 6. Eventually, the water and residue will enter the collecting bag 17. An external pipeline can be used to connect to the discharge valve pipe 18, and the control valve on the discharge valve pipe 18 can be opened to discharge the water and residue in a centralized manner. In the present invention, the discharge valve pipe 18 and the water outlet valve pipe 19 used are both provided with control valves for controlling the closure of the pipeline.

[0052] like Figures 1 to 10 As shown, the middle part of the retractable and expandable movable pipe section 4 is connected with a water outlet valve pipe 19, which is located between the lowermost atomizing nozzle 1 and the arc-shaped material receiving trough body 6, wherein both sides of the inner wall of the arc-shaped material receiving trough body 6 are fixedly connected with a wall cleaning water pipe 20, and the wall cleaning water pipe 20 is connected to the water outlet valve pipe 19, and the bottom of the wall cleaning water pipe 20 is equidistantly provided with a plurality of trapezoidal drainage holes 21 on one side of the inner wall of the arc-shaped material receiving trough body 6. After the water is discharged in a fan-shaped manner through the trapezoidal drainage holes 21, the side wall of the arc-shaped material receiving trough body 6 is cleaned, wherein the bottom of the water outlet valve pipe 19 is connected with a vertical water outlet pipe 22, and the vertical water outlet pipe 22 penetrates the arc-shaped material receiving trough body 6, and the bottom of the vertical water outlet pipe 22 is provided with a wedge-shaped drain port 23 on one side of the inner wall of the arc-shaped material receiving trough body 6. After the water is discharged through the wedge-shaped drain port 23, it flows along the inner wall of the arc-shaped material receiving trough body 6 and flushes the residue, because the residue is generally The water in the water delivery pipe 3 is filled into the vertical water outlet pipe 22 and the two wall cleaning water pipes 20 by opening the control valve on the water outlet valve pipe 19. Because the inner arc surface of the arc-shaped material receiving trough 6 is open, it is also necessary to prevent water from splashing out of the arc-shaped material receiving trough 6. During use of the present invention, when water flows in the wall cleaning water pipe 20, it is discharged through a plurality of trapezoidal drainage holes 21. When the water is discharged between the trapezoidal drainage holes 21, it is discharged in a fan-shaped distribution and contacts the inner wall of the arc-shaped material receiving trough 6. By designing the shape of the trapezoidal drainage holes 21, the water discharge area is increased, and it is ensured that the water flows normally from the wall cleaning water pipe 20, so that the water can flush the inner wall of the arc-shaped material receiving trough 6 as far as possible without dead angles.

[0053] The water discharged through the vertical water outlet pipe 22 will directly contact the inner wall of the outer arc surface of the arc-shaped material receiving trough body 6 under the action of the wedge-shaped drain port 23, and the water will flow downward along the inner wall of the arc, so that the water will merge with the water discharged from the wall cleaning water pipe 20 and flow together in the direction of the collection bag 17, completing the flushing and discharge operation of the residue on the inner wall of the arc-shaped material receiving trough body 6.

[0054] like Figures 1 to 3 、 Figure 6 and Figure 7As shown, air flow slag blowing components are provided on both sides of the top of the mounting bracket 2, which are used to blow the residue after adsorbing moisture into the arc-shaped material receiving trough 6. The air flow slag blowing components include an air injection cylinder 24 and an air supply pipe 27. The two vertical sections 12 are fixedly connected to the air injection cylinder 24. The bottom end of the air injection cylinder 24 is connected to a curved conveying pipe 25. The bottom of the curved conveying pipe 25 is connected to multiple air blowing pipes 26 of the same size. The multiple air blowing pipes 26 are arranged in a stepped manner at the bottom of the curved conveying pipe 25, which are used to speed up the speed at which the residue falls into the arc-shaped material receiving trough 6 and prevent the atomized water from contacting the working end 35 of the laser tube cutting machine. The tops of the two air injection cylinders 24 are connected with an air supply pipe 27. During the process of cutting the pipe by the working end 35 of the laser tube cutting machine, the problem of residue sputtering will occur, and the residue will usually be sputtered divergently at the cutting contact point between the laser beam and the pipe. In the process of spraying atomized water using the atomizing nozzle 1, Atomized water is also sprayed toward the sputtering area of the residue. Therefore, the sputtered residue and the atomized water can fully contact each other. After the residue and the atomized water contact, in order to allow the residue and the atomized water to enter the arc-shaped material receiving trough 6 in time, gas is added to the two gas injection cylinders 24 through the air supply pipe 27, so that the gas enters the curved conveying pipe 25 and is finally discharged through multiple blowing pipes 26. The airflow drives the atomized water and the residue to move toward the arc-shaped material receiving trough 6, so that the atomized water and the residue can enter the arc-shaped material receiving trough 6 smoothly. In actual use, the atomized water and the residue still have the problem of random spreading. In order to prevent the atomized water and the residue from affecting the working end 35 of the laser tube cutting machine, the airflow is sprayed by the blowing pipe 26 to limit the moving area of the atomized water and the residue. The multiple blowing pipes 26 are arranged in a stepped manner, which is adapted to the sputtering area of the residue during the cutting process, ensuring that the residue is effectively blown downward.

[0055] like Figure 2 、 Figure 3 、 Figure 6 and Figure 7As shown, a tension connection mechanism is provided between the longitudinal movable pipe section 5 and the bottom of the mounting bracket 2, for adapting to the longitudinal movement of the longitudinal movable pipe section 5 in the mounting bracket 2, the tension connection mechanism includes a fixed water pipe 28 and a spring damper 30, both sides of the bottom of the U-shaped frame 8 are connected with fixed water pipes 28, a telescopic water pipe 29 is connected between the fixed water pipe 28 and the bottom of the longitudinal movable pipe section 5, a spring damper 30 is provided between the sliding plate 10 and the inner bottom wall of the U-shaped frame 8, when the moving piece 7 drives the expansion and contraction movable pipeline to move, the longitudinal movable pipe section 5 will perform adaptive longitudinal movement in the U-shaped frame 8, and in order to keep sufficient tension of the entire water delivery pipe 3 during the movement, when the longitudinal movable pipe section 5 and the sliding plate 10 move together, the spring damper 30 is adaptively extended and retracted to adapt to different positions of the longitudinal movable pipe section 5, and during the movement of the longitudinal movable pipe section 5, the telescopic water pipe 29 will also be extended and retracted, so that the fixed water pipe 28 and the longitudinal movable pipe section 5 are kept in communication;

[0056] A synchronous water supply component is arranged between the two fixed water pipes 28, and the synchronous water supply component includes a water supply pipeline 40. The two fixed water pipes 28 are connected with the water supply pipeline 40. A water delivery pump 41 is arranged in the power distribution chamber 32 of the laser tube cutting machine. The input end of the water delivery pump 41 is connected to the external water source, and the output end of the water delivery pump 41 is connected to the water supply pipeline 40. The water delivery pump 41 is started to deliver the water source to the water supply pipeline 40. The water then passes through the water supply pipeline 40, passes through the fixed water pipe 28, the telescopic water pipe 29 and the water delivery pipe 3 in turn, and the water is discharged through the atomizing nozzle 1 or the water outlet valve pipe 19.

[0057] The working principle of the water spraying and slag removal mechanism of the laser tube cutting machine:

[0058] Before the working end 35 of the laser tube cutting machine performs laser cutting on the tube, the driving motor 39 is first started according to the diameter of the tube to drive the rotating shaft 38 to rotate. The annular threaded disk 14 is driven to rotate through the meshing relationship between the bevel gear 1 36 and the bevel gear 2 37. Then, the movable seat 15 and the movable plate 7 threadedly connected to the annular threaded disk 14 begin to move. The movable plate 7 is used to drive the expansion and contraction movable pipe section 4 to move, and the position of the atomizing nozzle 1 and the arc-shaped material receiving trough 6 is adjusted. During the movement of the expansion and contraction movable pipe section 4, the longitudinal movable pipe section 5 and the sliding plate 10 are longitudinally moved together between the U-shaped frame 8 and the sliding trough frame 9 to adjust the position of the entire water delivery pipe 3. Then, the working end 35 of the laser tube cutting machine performs the cutting operation on the tube.

[0059] During the cutting operation, when the problem of residue splashing occurs, the water delivery pump 41 is started to deliver water to the water supply pipe 40. The water then passes through the water supply pipe 40, passes through the fixed water pipe 28, the telescopic water pipe 29 and the delivery pipe 3 in sequence, and is sprayed out through the atomizing nozzle 1, so that the atomized water is fully in contact with the residue, reducing the phenomenon of random splashing of the residue. Gas is added to the two gas injection cylinders 24 through the air supply pipe 27, so that the gas enters the curved delivery pipe 25 and is finally discharged through the multiple air blowing pipes 26. The air flow drives the atomized water and the residue to move toward the arc-shaped material receiving trough 6;

[0060] After the residue enters the arc-shaped receiving trough body 6, it will flow downward along the inner wall of the arc-shaped receiving trough body 6, then flow into the collecting bag 17, and finally be discharged through the discharge valve pipe 18. When the problem of residue retention occurs in the arc-shaped receiving trough body 6, the water in the water delivery pipe 3 is added to the vertical water outlet pipe 22 and the two wall cleaning water pipes 20 through the water outlet valve pipe 19, and the water will be discharged through multiple trapezoidal drainage holes 21. When the water is discharged between the trapezoidal drainage holes 21, It contacts the inner wall of the arc-shaped material receiving trough body 6 and flushes the inner wall of the arc-shaped material receiving trough body 6. The water discharged through the vertical water outlet pipe 22 will directly contact the inner wall of the outer arc surface of the arc-shaped material receiving trough body 6 under the action of the wedge-shaped drain outlet 23. The water flows downward along the inner wall of the arc, so that the water and the water discharged from the wall cleaning water pipe 20 merge and flow together in the direction of the collection bag 17, completing the flushing and discharge operation of the residue on the inner wall of the arc-shaped material receiving trough body 6.

[0061] In the second embodiment, the present invention is based on a water spraying slag removal mechanism for a laser tube cutting machine, and also proposes a water spraying slag removal method for a laser tube cutting machine, which specifically includes the following steps:

[0062] Step 1: Adjust the position: Before laser cutting the pipe, according to the pipe diameter, the driving assembly drives the annular threaded disk 14 to rotate, and adjust the position of the multiple movable pieces 7, so that the position of the expanding and contracting movable pipe section 4 changes accordingly, and the distance between the atomizing nozzle 1 and the pipe is adjusted;

[0063] Step 2: Water supply: Water is delivered to the fixed water pipe 28 through the synchronous water supply component, and then the water enters the delivery water pipe 3 through the telescopic water pipe 29;

[0064] Step 3: Spraying water to remove slag: During the cutting process, if slag splashing occurs, water is sprayed through the atomizing nozzle 1 to allow the atomized water to fully contact the slag to perform the slag removal operation;

[0065] Step 4: Airflow slag blowing: Gas is injected into the two air injection cylinders 24 through the air supply pipe 27, so that the gas enters the curved conveying pipe 25 and is finally discharged through multiple air blowing pipes 26. The airflow drives the atomized water and the residue to move toward the arc-shaped receiving trough 6.

[0066] Step 5: Discharge the residue: After the residue enters the arc-shaped material receiving trough 6 , it will flow downward along the inner wall of the arc-shaped material receiving trough 6 , then flow into the collection bag 17 , and finally be discharged through the discharge valve pipe 18 .

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
