Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to an automatically controlled metal plate and tube cutting device. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to melt, vaporize, ablate or reach the ignition point quickly, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece;

[0003] Considering that during laser cutting, tubes and plates are cut by high-temperature melting of the laser, the existing technology usually uses clamps to clamp the plates and tubes during cutting. If thinner plates are cut, not only may cutting errors occur due to bending of the plates during transportation, but manual adjustment may also be required because the clamping point cannot be cut. At the same time, due to the high temperature of laser cutting, if the workpiece is not cooled, it may cause deformation due to excessive temperature, affecting the yield rate.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 8As shown, the present invention is an automatically controlled metal plate and tube cutting device, comprising a base 1, a bracket 13 is arranged on the top of the base 1, and a laser cutter 132 is slidably connected to the bottom surface of the bracket 13 near the top;

[0034] The top of the base 1 is symmetrically fixedly connected with a first motor 121 and a fixing frame 12. The surface of the fixing frame 12 is provided with a driving hole. A driving shaft 122 is rotatably connected in the driving hole. One end of the driving shaft 122 is fixedly connected to the output shaft of the first motor 121. A traction unit 2 is arranged on the top of the base 1. The traction unit 2 is used to pull the metal plate and the pipe to the laser cutting range. The traction unit 2 includes an adjustment unit 3 and a support unit 4. The adjustment unit 3 is used to clamp and adapt to plates or pipes of different sizes. The support unit 4 is used to support plates or pipes.

[0035] The traction unit 2 also includes four water delivery blocks 21, which are arranged in a rectangular array. The water delivery blocks 21 close to the driving shaft 122 are fixedly connected to the base 1, and the water delivery blocks 21 away from the driving shaft 122 are slidably connected to the base 1. The inner wall of the water delivery block 21 is fixedly connected to a water delivery pipe; one end of the water delivery pipe away from the water delivery block 21 is sealed and rotatably connected to the traction shaft 22, and a cooling hole is opened in the traction shaft 22, and the cooling hole is connected to the water delivery pipe.

[0036] In this embodiment, considering that during laser cutting, the tubes and plates are cut by high-temperature laser melting, the prior art usually uses a clamp to clamp the plates and tubes during cutting. If a thin plate is cut, not only may the plate be bent during transportation, resulting in cutting errors, but also the clamping position may not be able to cut, requiring manual adjustment. At the same time, due to the high temperature of laser cutting, if the workpiece is not cooled, it may be too high in temperature and cause deformation, affecting the yield rate.

[0037] When laser cutting is performed, the first motor 121 is started first, so that the driving shaft 122 transfers the plate or tube to the traction unit 2. When the workpiece contacts the traction unit 2, the workpiece is introduced through the traction shaft 22. When the workpiece contacts all four traction shafts 22, laser cutting can be performed.

[0038] Since the plate is thin and may bend during transportation, if it is cut directly, the size of the finished product may be distorted due to the bending of the plate. The four traction shafts 22 can be set to press the plate after it enters, so that the bent plate can be flattened to avoid affecting the cutting yield due to bending.

[0039] When cutting the pipe, the pipe is wrapped by four traction shafts 22, and the traction shafts 22 are rotated in the same direction, so that the pipe is not only clamped by the traction shafts 22, but also rotates synchronously due to the rotation of the traction shafts 22. At this time, when laser cutting is performed, the laser cutter 132 can cut the pipe without adjusting the focal length and moving;

[0040] During cutting, the coolant is introduced into the cooling hole through the water pipe, so that the coolant and the traction shaft 22 can exchange heat, so that the traction shaft 22 always maintains the same temperature. Since the traction shaft 22 is always in contact with the workpiece, the traction shaft 22 will conduct the temperature of the workpiece during cutting to avoid deformation caused by excessive temperature of the workpiece. After the workpiece is cut and melted, some of the melted metal may adhere to the cut workpieces. After the cut workpiece is pushed in, the workpiece may be reconnected due to contact. The workpiece is cooled by the traction shaft 22, and the molten metal can be quickly solidified after the plate is cut. Since the workpieces on both sides of the cutting are cooled, the cooling efficiency is high, and the melted metal has solidified before the workpiece is pushed in, so the workpiece can be prevented from being reconnected.

[0041] Specifically, the adjustment unit 3 includes two first adjustment rods 32, the inner wall of the first adjustment rod 32 is slidably connected to the second adjustment rod 321, the first adjustment rod 32 and the second adjustment rod 321 are both hinged to the two traction shafts 22 away from the driving shaft 122, and the first adjustment rod 32 and the second adjustment rod 321 are both hinged to the two traction shafts 22 away from the driving shaft 122; the first adjustment rod 32 and the second adjustment rod 321 are both fixedly connected to the third adjustment rod 33 on the side away from the driving shaft 122, the outer wall of the third adjustment rod 33 is slidably connected to the fourth adjustment rod 331, and the fourth adjustment rod 331 is respectively hinged to the two traction shafts 22 close to the driving shaft 122;

[0042] An adjusting slot 17 is provided on the top of the base 1, and a first adjusting shaft 31 is slidably connected in the adjusting slot 17. The width of the adjusting slot 17 is longer than the diameter of the first adjusting shaft 31. A second adjusting shaft 311 is slidably connected to the inner wall of the first adjusting shaft 31. An adjusting block 312 is fixedly connected to the top of the second adjusting shaft 311, and a clamping block 313 is fixedly connected to one end of the adjusting block 312. The surfaces of the second adjusting rod 321 and the third adjusting rod 33 close to the second adjusting rod 321 are both provided with clamping holes, and the clamping block 313 is slidably connected to the clamping hole.

[0043] In this embodiment, when cutting workpieces of different thicknesses and lengths, the position of the first adjustment shaft 31 and the height of the second adjustment shaft 311 can be adjusted by controlling the position of the adjustment block 312, and the clamping block 313 can follow the adjustment position and height. When the position and height of the clamping block 313 change, the second adjustment rod 321 will slide in the first adjustment rod 32, and the third adjustment rod 33 will slide in the fourth adjustment rod 331, thereby adjusting the height of the traction shaft 22 and the spacing between the traction shafts 22.

[0044] Specifically, a limiting tooth 314 is provided on the side of the second adjustment shaft 311 close to the traction shaft 22, and a limiting block 332 is fixedly connected to the surface of the third adjustment rod 33 away from the first adjustment rod 32, and the limiting block 332 is in sliding contact with the limiting tooth 314, and the bottom of the limiting block 332 is slidably connected to the top of the first adjustment shaft 31.

[0045] In this embodiment, after adjusting the height of the traction shaft 22, the limit block 332 can be brought into contact with the limit tooth 314 by pushing the first adjustment shaft 31 inward. Since the limit block 332 is fixed to the top of the first adjustment shaft 31, and the limit block 332 is fixed to the surface of the third adjustment block 312, the limit block 332 is always in contact with the top of the first adjustment shaft 31 when adjusting the height, and the limit block 332 is engaged with the limit tooth 314 after adjusting the height, so that the second adjustment shaft 311 cannot fall, thereby fixing the height of the traction shaft 22. The mechanical engagement fixing method can reduce the energy consumed by using the motor to lift the adjustment shaft for a long time, and at the same time, different heights can be fixed by engaging different limit teeth 314.

[0046] Specifically, the end of the traction shaft 22 close to the driving shaft 122 away from the water delivery block 21 is fixedly connected to the second motor 24, and the second motor 24 can attach static electricity to the surface of the traction shaft 22; the two traction shafts 22 close to the driving shaft 122 are used for grinding plates or pipes; the water delivery block 21 close to the driving shaft 122 and the side of the second motor 24 away from each other are fixedly connected with a debris removal plate 25, and the debris removal plate 25 is in contact with the surface of the traction shaft 22, and the debris removal plate 25 is used to remove and block impurities on the traction shaft 22; the surface of the base 1 is provided with a debris removal port 14.

[0047] In this embodiment, considering that impurities often stick to the surface of the workpiece during storage and transportation, some metal surfaces may have burrs, which may cause the thickness of the workpiece to be unable to be accurately measured during laser cutting;

[0048] Before the workpiece is cut, it will be polished by two traction shafts 22 close to the driving shaft 122 to remove impurities and burrs on the surface of the workpiece, and the second motor 24 will attach static electricity to the surface of the traction shaft 22, so that the impurities after polishing can be adsorbed by static electricity, and the impurities will be transferred to the impurity removal plate 25 through the rotation of the traction shaft 22; when the workpiece is cut, the second motor 24 will be powered off to make the surface of the traction shaft 22 lose static electricity. At this time, the impurities on the surface of the traction shaft 22 cannot be adsorbed. The impurities at this time will fall by gravity and be discharged from the equipment after falling into the impurity discharge port 14; through the above operation, the impurities or burrs on the surface of the workpiece can be prevented from affecting the laser cutting. The impurities and burrs on the surface of the workpiece can be removed by polishing, and the surface of the workpiece can be made smoother, so that the workpiece cutting is smoother and the yield rate of laser cutting is increased.

[0049] Specifically, a support groove 15 is provided at the top of the base 1, and an adjustment plate 45 is slidably connected in the support groove 15. A support plate 48 is fixedly connected to the top of the adjustment plate 45, and a sliding plate 47 is fixedly connected to the bottom of the adjustment plate 45. A support spring 46 is fixedly connected to the bottom of the sliding plate 47, and one end of the support spring 46 away from the sliding plate 47 is fixedly connected to a traction plate 44, and the traction plate 44 contacts the inner bottom surface of the base 1.

[0050] In this embodiment, it is considered that when cutting larger-sized plates and pipes, clamping them only by four traction shafts 22 may cause the middle of the plate to bend due to gravity, which may cause cutting errors during laser cutting due to the bending. At the same time, the pipe may slide due to insufficient force-bearing area, resulting in failure to cut normally.

[0051] By setting the adjusting plate 45, the sliding plate 47 and the supporting plate 48, the plate can be supported when it is bent, and when the size of the workpiece is large, the supporting spring 46 can be compressed by the sliding plate 47, so that the supporting plate 48 can adapt to the size of the workpiece, so that when supporting larger-sized pipes, the supporting area for the pipe fittings can be increased.

[0052] Specifically, a traction groove 16 is provided on the top of the base 1, and a sliding block 41 is slidably connected to the inner wall of the traction groove 16, and the sliding block 41 is hinged to the traction shaft 22. The bottom of the sliding block 41 is fixedly connected to a traction block 42, and one side of the traction block 42 is fixedly connected to an adjusting cylinder 43. The adjusting cylinder 43 and the traction block 42 are both slidably connected to the inner bottom surface of the base 1, and the adjusting cylinder 43 is fixedly connected to the traction plate 44. A supporting airbag is fixedly connected between the traction plate 44 and the sliding block 41, and the supporting airbag is connected to the adjusting cylinder 43.

[0053] In this embodiment, considering that the traction shaft 22 will move horizontally, the spacing will also increase after the traction shaft 22 moves. At this time, the length of the plate suspended in the air is also long, which may cause the plate to bend due to gravity;

[0054] When the traction shaft 22 moves horizontally, the sliding block 41 will drive the traction block 42 to move along, and when the traction block 42 moves, it will drive the adjusting cylinder 43 to move. Since the adjusting cylinder 43 is fixedly connected to the traction plate 44, and the adjusting cylinder 43 is connected to the supporting airbag, when the adjusting cylinder 43 moves, the traction plate 44 will pull the sliding plate 47 to move through the supporting spring 46, and at this time, it will drive the supporting plate 48 to move at the same time. When the traction wheel moves, it will make the supporting plate 48 move synchronously, so that the supporting plate 48 always supports the workpiece to avoid bending of the workpiece due to excessive length and lack of support.

[0055] Specifically, a spline shaft 23 is fixedly connected to one side of the water pipe away from the traction shaft 22 , and the spline shaft 23 is slidably connected to the base 1 .

[0056] In this embodiment, the spline shaft 23 can be set so that the end of the traction shaft 22 away from the adjustment unit 3 can also move synchronously, and the traction shaft 22 is always parallel, avoiding the angle of the traction shaft 22 being offset due to force on one end of the traction shaft 22.

[0057] Specifically, two sets of telescopic frames 131 are slidably connected to the top of the base 1, the telescopic frames 131 are slidably connected to the base 1, the outer walls of the telescopic frames 131 are slidably connected to the bracket 13, and the bottom surface of the bracket 13 on one side close to the water pipe is fixedly connected to a follower plate 133, the follower plate 133 is fixedly connected to the water pipe, and the follower plate 133 is used to keep the bracket 13 between the traction shafts 22.

[0058] In this embodiment, in the prior art, when the size of the workpiece changes, the focal length of the laser cutter 132 needs to be adjusted. By setting the telescopic frame 131 and the follower plate 133, when the spacing and height of the traction shaft 22 change, the follower plate 133 pushes the bracket 13 to change its position, so that the distance between the bracket 13 and the laser cutter 132 and the workpiece is always consistent, reducing the steps of adjusting the laser cutter 132 and increasing the cutting efficiency.

[0059] When using,

[0060] First, when performing laser cutting, start the first motor 121 first, so that the driving shaft 122 transfers the plate or tube to the traction unit 2. When the workpiece contacts the traction unit 2, the workpiece will be introduced through the traction shaft 22. When the workpiece contacts all four traction shafts 22, laser cutting can be performed.

[0061] Secondly, when cutting workpieces of different thicknesses and lengths, the position of the first adjustment shaft 31 and the height of the second adjustment shaft 311 can be adjusted by controlling the position of the adjustment block 312, and the clamping block 313 can follow the adjustment position and height. When the position and height of the clamping block 313 change, the second adjustment rod 321 will slide in the first adjustment rod 32, and the third adjustment rod 33 will slide in the fourth adjustment rod 331, so as to adjust the height of the traction shaft 22 and the spacing between the traction shafts 22.

[0062] After adjusting the height of the traction shaft 22, the limit block 332 can be brought into contact with the limit tooth 314 by pushing the first adjustment shaft 31 inward. Since the limit block 332 is fixed to the top of the first adjustment shaft 31, and the limit block 332 is fixed to the surface of the third adjustment block 312, the limit block 332 is always in contact with the top of the first adjustment shaft 31 when adjusting the height, and the limit block 332 is engaged with the limit tooth 314 after adjusting the height, so that the second adjustment shaft 311 cannot fall, thereby fixing the height of the traction shaft 22. The mechanical engagement fixing method can reduce the energy consumed by using the motor to lift the adjustment shaft for a long time, and at the same time, different heights can be fixed by engaging different limit teeth 314.

[0063] At the same time, by setting the adjusting plate 45, the sliding plate 47 and the supporting plate 48, the plate can be supported when it is bent, and when the size of the workpiece is large, the supporting spring 46 can be compressed by the sliding plate 47, so that the supporting plate 48 can adapt to the size of the workpiece, so that when supporting a larger size of the pipe, the supporting area of ​​the pipe can be increased;

[0064] When the traction shaft 22 moves horizontally, the sliding block 41 will drive the traction block 42 to move along, and when the traction block 42 moves, it will drive the adjusting cylinder 43 to move. Since the adjusting cylinder 43 is fixedly connected to the traction plate 44, and the adjusting cylinder 43 is connected to the supporting airbag, when the adjusting cylinder 43 moves, the traction plate 44 will pull the sliding plate 47 to move through the supporting spring 46, and at this time, it will drive the supporting plate 48 to move at the same time. When the traction wheel moves, it will make the supporting plate 48 move synchronously, so that the supporting plate 48 always supports the workpiece to avoid bending of the workpiece due to excessive length and lack of support.

[0065] Then, before the workpiece is cut, it is ground by two traction shafts 22 close to the driving shaft 122 to remove impurities and burrs on the surface of the workpiece, and the surface of the traction shaft 22 is attached with static electricity by the second motor 24, so that the impurities after grinding are adsorbed by static electricity, and the impurities are transferred to the impurity removal plate 25 through the rotation of the traction shaft 22;

[0066] When the workpiece is cut, the second motor 24 is powered off to make the surface of the traction shaft 22 lose static electricity. At this time, the impurities on the surface of the traction shaft 22 cannot be adsorbed. The impurities at this time will fall by gravity and be discharged from the equipment after falling into the impurity discharge port 14. The above operation can prevent the impurities or burrs on the surface of the workpiece from affecting the laser cutting. The impurities and burrs on the surface of the workpiece can be removed by grinding. At the same time, the surface of the workpiece can be made smoother, making the workpiece cutting smoother and increasing the yield rate of laser cutting.

[0067] Finally, since the plate is thin and may bend during transportation, if it is cut directly, the size of the finished product may be distorted due to the bending of the plate. The four traction shafts 22 can be set to press the plate after it enters, so that the bent plate can be flattened to avoid affecting the cutting yield due to bending.

[0068] When cutting the pipe, the pipe is wrapped by four traction shafts 22, and the traction shafts 22 are rotated in the same direction, so that the pipe is not only clamped by the traction shafts 22, but also rotates synchronously due to the rotation of the traction shafts 22. At this time, when laser cutting is performed, the laser cutter 132 can cut the pipe without adjusting the focal length and moving;

[0069] During cutting, the coolant is introduced into the cooling hole through the water pipe, so that the coolant and the traction shaft 22 can exchange heat, so that the traction shaft 22 always maintains the same temperature. Since the traction shaft 22 is always in contact with the workpiece, the traction shaft 22 will conduct the temperature of the workpiece during cutting to avoid deformation caused by excessive temperature of the workpiece;

[0070] After the workpieces are cut and melted, some of the molten metal may adhere to the cut workpieces. After the cut workpieces are pushed in, the workpieces may be reconnected due to contact. By cooling the workpieces through the traction shaft 22, the molten metal can be quickly solidified after the plate is cut. Since the workpieces on both sides of the cut are cooled, the cooling efficiency is high. The melted metal has solidified before the workpieces are pushed in, which can avoid reconnection of the workpieces.
