Description

Technical Field

[0001] The invention belongs to the field of optical fiber laser cutting equipment, and in particular relates to an optical fiber laser cutting machine for pipes. Background Art

[0002] Fiber laser is a new type of fiber laser developed internationally. It outputs a high-energy-density laser beam and focuses it on the surface of the workpiece, causing the area on the workpiece irradiated by the ultra-fine focal spot to melt and vaporize instantly. Automatic cutting is achieved by moving the spot irradiation position through a CNC mechanical system. When fiber laser cuts pipes, due to the cylindrical shape of the pipe, a large amount of dust and waste residue is often generated in the pipe during the cutting process. In addition, due to the high-heat characteristics of fiber laser cutting, dust, waste residue and other dirt are usually knocked off by the high-temperature laser beam. If it is not cleaned in time and the high heat dissipates, the dust and waste residue will solidify and agglomerate in the pipe. At that time, it will be extremely difficult to clean it up. However, if it is not cleaned up, it will cause problems in the subsequent use of the pipe. Therefore, it is of great significance to design a fiber laser cutting machine that can clean dust and waste residue in time during the pipe cutting process. Summary of the invention

[0035] Furthermore, support columns 11 are provided at the four corners of the bottom end surface of the frame 10 , and a pump 26 is provided below the frame 10 .

[0036] Working principle: The operator inserts the hollow tube to be laser cut through the center of the fixed ring frame 21, inserts one end of the tube into the center of the rotating cylinder 20 and pushes it inward. During the pushing process, the hollow part of the tube will wrap the multi-stage telescopic rod 39 and the cleaning base 40, and will drive the end face of the tube to contact the outer end face of the connecting tube barrel 38, thereby pushing the connecting tube barrel 38 to move inward, thereby pushing the telescopic pressure plate 28 at one end of the connecting tube barrel 38. The multi-stage telescopic rod 39 moves inward, thereby squeezing the hydraulic oil in the telescopic pressure cylinder 27 at the bottom of the telescopic pressure plate 28, so that a part of the hydraulic oil at the bottom of the telescopic pressure cylinder 27 enters the bottom of the pushing pipe 32 through the pushing pipe air inlet 33, thereby pushing the pushing plate 35 in the pushing pipe 32 to move outward, thereby pushing the pushing rod 36 at one end of the pushing plate 35 to move outward, so that the outer end surface of the pushing rod 36 will contact the bottom of the multi-stage telescopic rod 39 moving inward, thereby hitting the bottom of the multi-stage telescopic rod 39, thereby pushing the multi-stage telescopic rod 39 toward the inner hole of the pipe, thereby pushing the cleaning base 40 at one end of the multi-stage telescopic rod 39 and the rotating ball 23 to move into the pipe.

[0037] The movement of the telescopic pressure cylinder 27 drives a part of the hydraulic oil to move toward the air inlet 33 of the pushing pipe, and the other part will enter the connecting pipe 31, and then enter the rotating bin 45 through the connecting pipe 31, thereby pushing the rotating push plate 47 in the rotating bin 45 to move outward, thereby pushing the third drive motor 48 arranged at one end of the rotating push plate 47 to move outward, thereby pushing the rotating wheel 49 at one end of the third drive motor 48 to move outward, so that the outer cylindrical surface of the rotating wheel 49 contacts the outer side of the pipe extending into the rotating air cylinder 20.

[0038] When the telescopic pressure cylinder 27 moves to the limit, the two fixed ring frames 21 start to work, thereby driving the ring frame air inlet 22 to start intake of air. The gas entering the fixed ring frame 21 will enter the bottom of the clamping pipe 55 through the clamping pipe air inlet 56, thereby pushing the clamping push rod 60 in the clamping pipe 55 to move outward, thereby pushing the flexible clamping plate 58 at the other end of the clamping push rod 60 to move outward, thereby pushing the flexible contact protrusion 59 set at one end of the flexible clamping plate 58 to move outward, so that the flexible contact protrusion 59 first contacts the surface of the pipe, and then the inner wall surface of the flexible clamping plate 58 contacts the surface of the pipe, and is fixed through the combined contact of point and surface, so that the wall pipe slips and rotates.

[0039] At this time, the cutting head 43 is preheated, and the magnetic block 44 is started during the preheating process of the cutting head 43. At this time, the movable slide 14 will also move the magnetic block 44 to the side close to the cleaning base 40 until suction is generated between the magnetic block 44 and the driving magnet 61, so that in the subsequent movement process, the magnetic block 44 can drive the driving magnet 61 to move, thereby pulling the rotating ball 23 at one end of the driving magnet 61 to move.

[0040] When the magnetic block 44 is linked with the driving magnet 61, the cutting head 43 starts to perform laser cutting. During the cutting process, the first driving motor 16 is started, and the output end of the first driving motor 16 drives the first gear 17 to rotate, thereby driving the second gear 18 meshing therewith to rotate, thereby driving the meshing wheel 54 with the second gear 18 at one end to rotate, so that the meshing wheel 54 rotates in the arc groove 25, thereby driving the sliding box 19 outside the meshing wheel 54 to move in a circle on the arch track 15, thereby driving the cutting head 43 under the sliding box 19 to move in a circle, so that the equipment can perform multi-angle laser cutting.

[0041] During the laser cutting process, since the magnetic block 44 is linked with the driving magnet 61, the driving magnet 61 will also move when the second driving motor 41 moves, thereby driving the brush table 52 and the rotating ball 23 provided with the driving magnet 61 to move. Therefore, during the laser cutting process, the second driving motor 41 arranged in the cleaning base 40 will also be started, and the output end of the second driving motor 41 drives the inner rotating rod 53 to rotate, thereby driving the inner cleaning plate 50 outside the inner rotating rod 53 to rotate. Since the inner cleaning plate 50 can contact the inner wall surface of the rotating ball 23, it will drive the rotating ball 23 to rotate, thereby driving the rotating ball 2 The brush table 52 on the outer circumferential surface rotates, thereby driving the rotating bristles 24 on the outer end surface of the brush table 52 to rotate, so that the outer circumferential surface of the rotating bristles 24 can contact the inner wall surface of the pipe. During the start-up process of the second driving motor 41, the connecting hose 42 arranged on the cleaning base 40 also generates suction force, thereby driving the dust suction slot 51 on the outer side of the rotating ball 23 to generate an inward suction force, so that the smoke and dust and other impurities generated during the laser cutting process can be adsorbed and cleaned in cooperation with the rotating bristles 24. In addition, due to the inner cleaning plate 50, the dust suction slot 51 can be cleaned during the adsorption process, thereby avoiding clogging of the dust suction slot 51.

[0042] If one side of the tube has been cut and needs to be changed, since the rotating wheel 49 has been in contact with the outer side of the tube when it is placed, the fixed ring frame 21 can release a certain clamping force and drive the third drive motor 48 to start. The output end of the third drive motor 48 drives the rotating wheel 49 to rotate, thereby driving the outer cylindrical surface of the tube in contact with the rotating wheel 49 to rotate, thereby moving the outer cylindrical surface of the tube.

[0043] When the pipe processing is completed, the magnetic block 44 will drive the driving magnet 61 and the cleaning base 40 fixed with the driving magnet 61 to move to the end face of the rotating air cylinder 20 for return. The magnetic block 44 stops moving, and the fixed ring frame 21 releases the clamping, so that the telescopic pressure plate 28 returns to its position outward under the action of the first spring 29, so that the hydraulic oil inside the telescopic pressure cylinder 27 is recovered, so that the push plate 35 returns to its position under the action of the bottom pushing pipe 32, so that the rotating push plate 47 returns to its position under the action of the third spring 46 at the bottom.
