Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and more specifically, to a laser cutting device and cutting process for steel plate processing with high auxiliary anti-deviation capability. Background Technology

[0002] Steel plate laser cutting equipment mainly uses fiber lasers, relying on high energy density laser beams to melt steel plates, and auxiliary gas to blow away slag. The CNC system completes complex contour cutting.

[0003] Chinese Patent Publication No. CN113042908A discloses a laser cutting device for steel plates with a guiding mechanism and its usage method. The device includes a cutting body, a cutting electric cylinder installed on the upper side of the inner wall of the cutting body, a laser cutting head installed on the slider of the cutting electric cylinder, movable moving plates installed on opposite side walls of the cutting body, an electric push rod installed inside the moving plate, a connecting seat installed on the telescopic shaft of the electric push rod, multiple rotating shafts installed inside the connecting seat, and guide wheels for guiding the steel plate installed on the multiple rotating shafts.

[0004] The above-mentioned technical solutions are easy to assemble and install, convenient to fix and transport, have good guiding and correction effects, and are highly versatile. Although the motion actuators of existing laser cutters can provide basic positioning accuracy, under high-speed or long-stroke conditions, the lack of a dedicated anti-deviation auxiliary device in existing equipment can cause deviations in the kerf position when the laser cutter cuts the steel plate. In severe cases, this can lead to scrapping of the plate, affecting the cutting quality and yield of the steel plate. Moreover, during storage, transportation, and pretreatment, the surface of the steel plate is often covered with oxide scale, iron filings, oil stains, or dust. If these are not removed before cutting, the laser beam will scatter or absorb energy fluctuations when penetrating these foreign objects, resulting in quality defects such as slag buildup at the cut, accelerated oxidation, or incomplete cutting. Although some existing solutions have added independent air-blowing nozzle cleaning devices, additional control lines and power transmission paths are required, which not only makes the equipment structure more complex and increases manufacturing costs, but also increases the daily power consumption and maintenance workload.

[0012] Preferably, a limiting block is fixedly installed on the inner side of the support frame, and a connecting horizontal plate that slidably connects to the side of the steel plate body is slidably connected inside the two support frames. The connecting horizontal plate is located below the limiting block.

[0016] A laser cutting process for steel plate processing with high-assistance anti-deviation features the following steps:

[0017] S1: First, according to the length to be cut, place the steel plate body on the surface of the cutting device and slowly push the steel plate body. When the position sensor detects the edge position of the steel plate body, the position sensor transmits the signal to the controller. The controller receives and processes the signal, and the controller controls the buzzer to work and emit a buzzing sound to stop pushing the steel plate body.

[0018] S2: The telescopic device extends and moves the lifting plate and laser cutter toward the steel plate body. The movement of the lifting plate moves the two side plates one downwards. The movement of the two side plates one moves the two rotating wheels downwards. When the two rotating wheels contact the surface of the two outer movable frames, the downward movement of the lifting plate also moves the two side plates two. The movement of the two side plates two respectively moves the two flexible brush discs and grinding discs downwards to contact the surface of the steel plate body.

[0019] S3: During the operation of the laser cutter, the lifting plate moves, causing the two side plates to move, which in turn causes the two rolling wheels to roll inside the roller grooves. The two rotating wheels roll on the top surfaces of the two movable frames. The two spline rods rotate in opposite directions, causing the two flexible brush discs to rotate in opposite directions. The flexible brush discs rotate in opposite directions to clean the debris at the cutting position on the surface of the steel plate. The motor rotates, causing the spline cylinder to rotate, which in turn causes the spline rod to rotate, causing the grinding disc to rotate at high speed. The rotating grinding disc grinds the cutting position on the steel plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1) When using this high-auxiliary anti-deviation laser cutting equipment for steel plate processing, during the movement of the laser cutter, the lifting plate moves along with the two side plates, causing the two rolling wheels to roll inside the roller grooves and the two rotating wheels to roll on the top surfaces of the two movable frames. This ensures stable cutting of the steel plate by the laser cutter, prevents positional deviation during cutting of the steel plate, and improves the cutting quality and yield of the steel plate.

[0022] 2) When using this high-auxiliary anti-deviation laser cutting equipment for steel plate processing, during the laser cutter's movement to cut the steel plate body, the lifting plate moves, causing the two side plates to move, making gear one rotate on the surface of the gear plate. The rotation of gear one causes gear two to rotate. Gear one and gear two rotate at the bottom of side plate two through shaft one and shaft two. The rotation of gear one and gear two causes spline cylinder one to rotate, and the rotation of spline cylinder one causes spline rod one to rotate. At this time, the two spline rods one rotate in opposite directions, causing the two flexible brush disks to rotate in opposite directions. The flexible brush disks rotate in opposite directions to clean the debris at the cutting position on the surface of the steel plate body. When the laser cutter cuts the steel plate body, it prevents debris from scattering or absorbing energy fluctuations, which may cause slag on the cut, accelerated oxidation, or incomplete cutting, thus ensuring the cutting quality of the steel plate body by the laser cutter.

[0023] 3) When using this high-assistance anti-deviation laser cutting equipment for steel plate processing, the motor rotates while the laser cutter is cutting the steel plate body. This rotation causes the spline cylinder to rotate, which in turn causes the grinding disc to rotate at high speed. The grinding disc grinds the cutting position of the steel plate body, which not only improves the processing efficiency of the steel plate body, but also improves the cutting quality of the kerf position of the steel plate body.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1 - Figure 14A laser cutting device for steel plate processing with high auxiliary anti-deviation includes a cutting device 1 and a steel plate body 2 placed on its surface. The cutting device 1 is a laser cutting device, and the steel plate body 2 is a conventional steel plate body 2 in the prior art. Two support frames 3 are symmetrically fixedly installed on the surface of the cutting device 1. The inner walls of the two support frames 3 are jointly fixedly installed with a fixing frame 4. The interior of the two fixing frames 4 is slidably connected with matching sliding plates 5. The surface of each sliding plate 5 is provided with roller grooves 6. Two rolling wheels 14 roll inside the roller grooves 6, ensuring stable cutting of the steel plate body 2 by the laser cutter 11. Moreover, the rolling wheels 14 inside the roller grooves 6 are connected to the gear 1. 7. When the toothed plate 7 rotates on its surface, the rolling wheel 14 can limit the sliding plate 5 inside the roller groove 6 to prevent the toothed plate 7 from disengaging from the gear 17. The toothed plates 7 are fixedly installed on the inner surfaces of the two sliding plates 5, and the wedge blocks 8 are fixedly installed on the bottom surface of the toothed plates 7. The function of the wedge blocks 8 is that when the movable frame 9 is reset under the action of the spring 30, the movable frame 9 squeezes the wedge blocks 8, causing the sliding plate 5 to retract into the fixed frame 4, thereby realizing that the toothed plate 7 follows the sliding plate 5 into the fixed frame 4 (the elastic force of the spring 30 is greater than that of the spring 27). The movable frame 9 is set on the outside of the fixed frame 4, and a lifting plate 10 that can move vertically up and down is set above the steel plate body 2. A laser cutter 11 for cutting the steel plate body 2 is fixedly installed on the bottom surface of the plate 10. The laser cutter 11 is a conventional laser cutter 11 in the prior art. Two side plates 12 are fixedly installed on the symmetrical surfaces of the lifting plate 10, and two side plates 13 are fixedly installed on the symmetrical side surfaces of the lifting plate 10. Rolling wheels 14 corresponding to and matching the positions of the roller grooves 6 are rotatably connected to the bottom surfaces of the two side plates 12. A rotating shaft 15 and a rotating shaft 16 are rotatably connected to the bottom surface of one of the side plates 13. Gear 17 and gear 18 are fixedly installed on the bottom surfaces of the rotating shaft 15 and the rotating shaft 16, respectively. Gear 17 and gear 18 mesh with each other. Gear 17 and gear 2 are positioned and meshed with each other. A flexible brush disc 19 for cleaning impurities on the surface of the steel plate body 2 is provided below gear 17 and gear 2. The flexible brush disc 19 is used to clean the surface of the steel plate body 2. During the movement of the laser cutter 11, the lifting plate 10 moves and moves the two side plates 12, so that the two rolling wheels 14 roll inside the roller groove 6 and the two rotating wheels 25 roll on the top surface of the two movable frames 9. This ensures the stable cutting of the steel plate body 2 by the laser cutter 11, prevents positional deviation when the laser cutter 11 cuts the steel plate body 2, and improves the cutting quality and yield of the steel plate body 2.During the cutting process of the steel plate body 2 by the laser cutter 11, the lifting plate 10 moves, causing the two side plates 13 to move, which in turn causes gear 17 to rotate on the surface of the toothed plate 7. The rotation of gear 17 causes gear 18 to rotate. Gear 17 and gear 18 rotate at the bottom of side plate 13 via rotating shaft 15 and rotating shaft 16. The rotation of gear 17 and gear 18 causes spline cylinder 20 to rotate, which in turn causes spline rod 21 to rotate. At this time, the two spline rods 21 rotate towards each other, causing the two flexible brush disks 19 to rotate towards each other. The flexible brush disks 19 rotate towards each other to clean the debris at the cutting position on the surface of the steel plate body 2. When the laser cutter 11 cuts the steel plate body 2, it prevents debris from scattering or absorbing energy fluctuations, which could cause slag buildup, accelerated oxidation, or incomplete cutting, thus ensuring the cutting quality of the steel plate body 2 by the laser cutter 11.

[0041] Please see Figure 12 - Figure 14 Gear 2 18 is smaller than gear 17. The flexible brush disk 19 is curved. Splined cylinders 20 are fixedly installed on the bottom surfaces of both gear 17 and gear 2 18. Splined rods 21 are splinedly connected inside both splined cylinders 20. Springs 22 are elastically connected between splined rods 21 and splined cylinders 20. Springs 22 are used for the reset movement of splined rods 21. One end of springs 22 is fixedly connected to splined rods 21, and the other end of springs 22 is fixedly connected to splined cylinders 20. The design of splined rods 21 and splined cylinders 20 allows splined rods 21 to slide inside splined cylinders 20, and also allows the rotation of splined cylinders 20 to rotate splined rods 21.

[0042] Please see Figure 12 - Figure 14 Both flexible brush discs 19 are provided with ball bearings 23 on the bottom surface of their middle section. The ball bearings 23 reduce the friction between the bottom surface of the flexible brush disc 19 and the surface of the steel plate body 2, ensuring that the flexible brush disc 19 works smoothly. Both side plates 12 are slidably connected with through-type lifting rods 24. Both lifting rods 24 are provided with rollers 25 on their bottom surfaces. The rollers 25 correspond to the position of the movable frame 9, and the rollers 25 roll on the top surface of the movable frame 9.

[0043] Please see Figure 5 - Figure 11 Both lifting rods 24 are fitted with springs 26 for resetting their movement. Springs 26 are used to reset the lifting rods 24. Springs 3 and 27 are elastically connected between the slide plate 5 and the fixed frame 4. Springs 3 and 27 cause the slide plate 5 to slide out from inside the fixed frame 4. One end of springs 3 and 27 is fixedly connected to the slide plate 5, and the other end of springs 3 and 27 is fixedly connected to the fixed frame 4.

[0044] Please see Figure 5 - Figure 9 Each support frame 3 has a groove 28 on its surface. A matching slide 29 is slidably connected inside the groove 28. The slide 29 is fixedly connected to the end surface of the movable frame 9. A spring 30 is elastically connected between the slide 29 and the groove 28. One end of the spring 30 is fixedly connected to the slide 29, and the other end of the spring 30 is fixedly connected to the groove 28. The elastic force of the spring 30 is less than that of the spring 26.

[0045] Please see Figure 5 - Figure 9 A limiting block 31 is fixedly installed on the inner side of the support frame 3. A connecting horizontal plate 32, which slidably connects to the side of the steel plate body 2, is slidably connected to the interior of both support frames 3. The surface of the connecting horizontal plate 32 is flush with the surface of the steel plate body 2. The function of the connecting horizontal plate 32 is to align with the side of the steel plate body 2 before the laser cutter 11 starts cutting from the side, ensuring that the connecting horizontal plate 32 is flush with the surface of the steel plate body 2. This prevents a height difference at the edge of the steel plate body 2, which would affect the subsequent grinding of the steel plate body 2 by the grinding disc 51. The connecting horizontal plate 32 is located below the limiting block 31. The cutting device 1... The surface of the lifting plate 10 is symmetrically fixedly mounted with uprights 33. The top surfaces of the two uprights 33 are jointly fixedly mounted with support frames 34. The bottom surface of the support frames 34 is mounted with an upper cross frame 35. The upper cross frame 35 is slidably connected with a matching slider 36. The bottom surface of the upper cross frame 35 is provided with a bottom groove 37 that communicates with it. The bottom groove 37 is slidably connected with a matching movable seat 38. The movable seat 38 is fixedly connected to the slider 36. The bottom surface of the movable seat 38 is fixedly mounted with a telescopic device 39. The telescopic device 39 is a conventional electrically controlled push rod in the prior art. The telescopic end of the telescopic device 39 is fixedly connected to the surface of the lifting plate 10.

[0046] Please see Figure 1 - Figure 4 The upper horizontal frame 35 is internally rotatably connected to a lead screw 40, which is threadedly connected to a slider 36. A motor 41 is fixedly mounted on the surface of one of the upright frames 33. The motor 41 is a conventional forward and reverse motor in the prior art. The output end of the motor 41 is fixedly connected to the lead screw 40. A ruler frame 42 is fixedly mounted on the inner side of both upright frames 33. The ruler frame 42 is a conventional ruler frame in the prior art, and the zero point of the ruler frame 42 corresponds to the position of the laser cutter 11. A transverse groove 43 is opened on the inner side of the ruler frame 42. A matching horizontal block 44 is slidably connected inside the transverse groove 43. A position sensor 45 for detecting the cutting length of the steel plate body 2 is fixedly mounted on the surface of the horizontal block 44. The position sensor 45 is a conventional position sensor in the prior art.

[0047] Please see Figure 1Another stand 33 has a controller 46 and a buzzer 47 fixedly mounted on its surface. The buzzer 47 is a conventional buzzer 47 in the prior art. The buzzer 47 is used for warning. The buzzer 47 is electrically connected to the controller 46. The controller 46 is a conventional programmable control device in the prior art. The controller 46 is electrically connected to the position sensor 45, the motor 41, and the telescopic device 39. The electrical appliances controlled by the controller 46 are in the prior art and will not be described in detail here.

[0048] Please see Figure 10 - Figure 14 Another side plate 13 has a splined cylinder 48 rotatably connected to its bottom surface. A splined rod 49 is splined inside the splined cylinder 48. A spring 50 is elastically connected between the splined rod 49 and the splined cylinder 48. A grinding disc 51 for grinding the cut surface is fixedly installed on the bottom surface of the splined rod 49. A motor 52 is fixedly installed on the surface of the other side plate 13. The motor 52 is the existing motor 52, and the motor 52 provides power for the rotation of the grinding disc 51. The output end of the motor 52 is fixedly connected to the splined cylinder 48. During the process of the laser cutter 11 cutting the steel plate body 2, the motor 52 rotates, causing the splined cylinder 48 to rotate, which in turn causes the splined rod 49 to rotate, causing the grinding disc 51 to rotate at high speed. The rotating grinding disc 51 grinds the cut position of the steel plate body 2, which not only improves the processing efficiency of the steel plate body 2, but also improves the cutting quality of the cut position of the steel plate body 2.

[0049] The steps for using this invention are as follows: When using this laser cutting equipment for steel plate processing with high auxiliary anti-deviation capability, firstly, adjust the position sensor 45 according to the length to be cut from the steel plate body 2, ensuring that the distance from the position sensor 45 to the zero point of the ruler frame 42 is the same as the length to be cut from the steel plate body 2. Then, place the steel plate body 2 on the surface of the cutting device 1 and slowly push it. When the position sensor 45 detects the edge position of the steel plate body 2, it transmits a signal to the controller 46. The controller 46 receives and processes the signal, and controls the buzzer 47 to emit a buzzing sound, stopping the pushing of the steel plate body 2. Then, according to the width specifications of the steel plate body 2, adjust the mating crossplates 32 on both sides of the steel plate body 2. Pushing in that direction, once the edges of the two connecting horizontal plates 32 are aligned with the side surfaces of the steel plate body 2, the pushing of the connecting horizontal plates 32 is stopped, and laser cutting of the steel plate body 2 begins. The controller 46 is operated; it first controls the motor 41 to rotate counterclockwise. The rotation of the motor 41 causes the lead screw 40 to rotate, which in turn causes the slider 36 to move towards the inner wall of the upper horizontal frame 35. The movement of the slider 36 moves the telescopic device 39, the lifting plate 10, and the laser cutter 11. When the slider 36 contacts the inner wall of the upper horizontal frame 35, the operation of the motor 41 is stopped. The telescopic device 39 extends, moving the lifting plate 10 and the laser cutter 11 towards the steel plate body 2. The movement of the lifting plate 10 moves the two side plates 12 downwards. As the two rotating wheels 25 move downwards, when they contact the surfaces of the two outer movable frames 9, the telescopic device 39 continues to extend. At this point, the two rotating wheels 25 press down on the two outer movable frames 9 (the elastic force of spring 26 is greater than that of spring 4 30). The two movable frames 9 move downwards simultaneously, carrying the slide 29 downwards within the slide groove 28, pressing down on spring 4 30. When the bottom surface of the movable frame 9 contacts the surface of the steel plate body 2, the two sliding plates 5, under the action of spring 3 27, respectively exit from inside the fixed frame 4. The movement of the two sliding plates 5 carries the roller groove 6, toothed plate 7, and wedge block 8. When the inner side of the bottom of the sliding plate 5 abuts against the inner side of the movable frame 9, the movement of the sliding plate 5 is complete. At this point, the telescopic device 39 continues to extend, and the two rotating wheels 25 are subjected to... The movable frame 9, which contacts the surface of the steel plate body 2, is pressed. The two rotating wheels 25 move upwards, causing the lifting rod 24 to move upwards and compress the second spring 26. At this time, the bottom surfaces of the two movable frames 9 are fixed to the steel plate body 2. The lifting plate 10 moves downwards, also causing the two side plates 13 to move. The two side plates 13 move downwards, respectively causing the two flexible brush discs 19 and the grinding disc 51 to contact the surface of the steel plate body 2. As the telescopic device 39 continues to extend, the two flexible brush discs 19 are pressed by the surface of the steel plate body 2, causing the spline rod 21 to move into the spline cylinder 20 and compress the first spring 22. The grinding disc 51 is pressed by the surface of the steel plate body 2, causing the spline rod 49 to move into the spline cylinder 48 and compress the fifth spring 50. As the telescopic device 39 continues to extend...The lifting plate 10 moves downwards, causing the two rolling wheels 14 to fall into the two roller grooves 6. At this time, the gear 17 moves downwards with the side plate 13 and meshes with the toothed plate 7. The bottom surface of the gear 17 contacts the surface of the wedge block 8. After the gear 17 meshes with the toothed plate 7, the telescopic device 39 stops working. Then the motor 41 starts working again and rotates clockwise. The rotation of the motor 41 causes the lead screw 40 to rotate, which in turn causes the slider 36 to move inside the upper cross frame 35, causing the telescopic device 39 to move laterally. The lateral movement of the telescopic device 39 causes the laser cutter 11 to move and cut the steel plate body 2. During the movement of the laser cutter 11, the lifting plate 10 moves, causing the two side plates 12 to move, so that the two rolling wheels 14 roll inside the roller grooves 6 and the two rotating wheels 25 roll on the top surfaces of the two movable frames 9. This ensures the stable cutting of the steel plate body 2 by the laser cutter 11, prevents positional deviation of the laser cutter 11 when cutting the steel plate body 2, and improves the cutting quality and yield of the steel plate body 2. ,

[0050] During the cutting process of the steel plate body 2 by the laser cutter 11, the lifting plate 10 moves, causing the two side plates 13 to move, which makes the gear 17 rotate on the surface of the toothed plate 7. The rotation of the gear 17 causes the gear 18 to rotate. The gear 17 and gear 18 rotate at the bottom of the side plate 13 through the rotating shaft 15 and rotating shaft 16. The rotation of the gear 17 and gear 18 causes the spline cylinder 20 to rotate, and the rotation of the spline cylinder 20 causes the spline rod 21 to rotate. At this time, the two spline rods 21 rotate towards each other, causing the two flexible brush disks 19 to rotate towards each other. The flexible brush disks 19 rotate towards each other to clean the debris at the cutting position on the surface of the steel plate body 2. When the laser cutter 11 cuts the steel plate body 2, it prevents the debris from scattering or absorbing energy fluctuations, which may cause slag on the cut, aggravate oxidation, or incomplete cutting, thus ensuring the cutting quality of the steel plate body 2 by the laser cutter 11.

[0051] During the process of laser cutter 11 cutting steel plate body 2, motor 52 rotates, causing spline cylinder 48 to rotate, which in turn causes spline rod 49 to rotate, causing grinding disc 51 to rotate at high speed. The rotating grinding disc 51 grinds the cutting position of steel plate body 2, which not only improves the processing efficiency of steel plate body 2, but also improves the cutting quality of the cutting seam of steel plate body 2.
