Description

Technical Field

[0001] This invention relates to the field of neodymium iron boron magnetic material processing technology, and in particular to a laser cutting machine for neodymium iron boron magnetic materials. Background Technology

[0002] Neodymium iron boron (NdFeB) permanent magnets are composite strong magnetic field permanent magnets composed of metallic neodymium and metallic cobalt. They function as energy storage materials in the form of ferrite, generating electromagnetic fields and outputting energy through charging and discharging. These materials possess excellent properties such as high energy product, high coercivity, and high remanence, making them widely used in electronics, machinery, and medical fields. This enables the miniaturization, weight reduction, and thinning of instruments, electroacoustic motors, magnetic separation and magnetization equipment, and medical devices. The advantages of NdFeB magnets are their high cost-effectiveness and good mechanical properties. However, their disadvantages include a low Curie temperature, poor temperature characteristics, and susceptibility to pulverization and corrosion. These issues must be addressed by adjusting their chemical composition and employing surface treatment methods to meet the requirements of practical applications.

[0003] Shortcomings of existing technology: Existing technology usually uses laser cutting to cut neodymium iron boron magnetic materials. However, existing devices produce debris that flies everywhere during the cutting process. The debris may also be magnetic and easily adhere to surrounding devices, affecting their normal use. In addition, due to the special properties of neodymium iron boron materials, the high temperature generated during laser cutting may cause edge deformation, melting, and other problems. These problems not only affect the appearance of the product but may also reduce its performance. Summary of the Invention

[0004] The problem that this invention aims to solve is that existing laser cutting devices produce debris that flies everywhere when cutting neodymium iron boron magnetic materials, and the high temperature generated during laser cutting may cause edge deformation and melting.

[0005] To solve the above-mentioned technical problems, the present invention provides a laser cutting machine for neodymium iron boron magnetic materials, including a cutting table and a cutting groove opened at the middle of its top. A device frame is provided on one side of the top of the cutting table. A protective component for preventing debris from splashing is fixedly connected to the inner cavity of the cutting groove. A linear guide rail is provided on the upper part of the inner wall of the device frame. A laser cutting device is movably connected to the linear guide rail. A spraying component for cooling and deslag removal is provided on the lower part of the outer surface of the laser cutting device. The protective assembly includes a splash guard fixedly connected to the inner cavity of the cutting groove. A mesh plate is fixedly connected to the middle of the inner cavity of the splash guard. Clamping assemblies for fixing neodymium iron boron magnetic materials are provided on both sides of the inner cavity of the splash guard. A drainage pipe is fixedly connected to one end of the inner cavity of the splash guard.

[0006] Preferably, the clamping assembly includes clamping plates movably connected to both sides of the top of the mesh plate. A limiting plate is fixedly connected to the top of the clamping plate. A connecting hole is provided on one side of the top of the limiting plate. An adjusting screw is threaded into the inner cavity of the connecting hole. A fastening block is fixedly connected to the bottom end of the adjusting screw.

[0007] Preferably, cylinders are fixedly installed at both ends of the splash shield, and the output end of the cylinder passes through the splash shield and is fixedly connected to the middle of one end of the clamping plate.

[0008] Preferably, the bottom end of the drainage pipe is inclined, the end of the drainage pipe away from the splash guard passes through the cutting table, and the drainage pipe is connected to the cutting groove.

[0009] Preferably, the spraying assembly includes a fixing plate sleeved on one side of the outer surface of the laser cutting equipment, with connecting rings fixedly connected to both sides of the bottom end of the fixing plate, a nozzle fixedly connected to the inner cavity of the connecting ring, and a flexible hose fixedly connected to the input end of the nozzle.

[0010] Preferably, the two nozzles are located on the left and right sides of the laser cutting equipment, respectively. The nozzles are set at an angle, and the end of the hose away from the nozzle passes through the equipment frame and is connected to the output end of an external water source device.

[0011] Preferably, a rack and a slider are fixedly connected to the top two sides of the cutting table, a groove is provided at one end of the equipment frame, a gear is provided in the inner cavity of the groove, and sliding grooves are provided on both sides of the bottom end of the equipment frame.

[0012] Preferably, one of the grooves is connected to the groove, the position of the gear corresponds to the position of the rack, the outer surface of the gear meshes with the top of the rack, and the other groove is slidably connected to the slider.

[0013] Preferably, a drive device is fixedly installed on the upper part of one end of the equipment frame, and a motor is fixedly installed on the lower part of the other end of the equipment frame. The output end of the drive device is fixedly connected to a linear guide rail, and the output end of the motor is fixedly connected to a gear.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention protects the debris generated during the cutting process by incorporating protective components. After the neodymium iron boron magnetic material is fixed on the mesh plate, it is cut by a laser cutting device. During the cutting process, a splash guard prevents the debris from splashing everywhere and avoids the possible magnetic debris from adhering to the surrounding equipment, which would affect the normal use of the equipment. At the same time, water is continuously sprayed onto the cutting area through nozzles to wash away the debris. The washed-away debris flows through the mesh plate into the inner cavity of the cutting groove. The wastewater stored in the inner cavity of the cutting groove is discharged centrally through a drainage pipe. Meanwhile, the splash guards around the perimeter prevent wastewater from splashing everywhere and causing environmental pollution.

[0015] 2. This invention utilizes a spraying assembly for cooling. During the laser cutting process, the nozzle is connected to an external water source via a hose, and water is sprayed onto the cutting area. Because the nozzle is angled, its output is always aligned with the cutting area of ​​the laser cutting equipment. This water spraying cools the cutting area of ​​the NdFeB magnetic material, preventing deformation or melting of the cutting edges caused by the high temperatures generated during cutting, thus ensuring the integrity of the NdFeB magnetic material's appearance after cutting.

[0016] 3. This invention uses a clamping assembly to fix neodymium iron boron magnetic materials. Before cutting, the cylinder is activated, which pushes two clamping plates towards the center. The clamping plates on both sides clamp and fix the neodymium iron boron magnetic materials to the top of the mesh plate. After fixing, the adjusting screw connected in the threaded connection in the limiting plate is rotated, so that the fastening block is fixed to the top of the neodymium iron boron magnetic materials. The fastening block increases the firmness and stability of the neodymium iron boron magnetic materials, avoiding vibrations during the cutting process that could cause the neodymium iron boron magnetic materials to shift in position, thus effectively improving the cutting effect of the device.

[0024] This invention provides a laser cutting machine for neodymium iron boron magnetic materials, such as... Figure 1 - Figure 6 As shown, it includes a cutting table 1 and a cutting groove 2 opened at the middle of its top. A device frame 3 is provided on one side of the top of the cutting table 1. A protective component 4 for preventing debris from splashing is fixedly connected to the inner cavity of the cutting groove 2. A linear guide rail 5 is provided on the upper part of the inner wall of the device frame 3. A laser cutting device 6 is movably connected to the linear guide rail 5. A spraying component 7 for cooling and deslag removal is provided on the lower part of the outer surface of the laser cutting device 6.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, the protective component 4 includes a splash guard 41 fixedly connected to the inner cavity of the cutting groove 2. A mesh plate 42 is fixedly connected to the middle of the inner cavity of the splash guard 41. Clamping components 43 for fixing neodymium iron boron magnetic materials are provided on both sides of the inner cavity of the splash guard 41. The neodymium iron boron magnetic material to be cut is fixed on the mesh plate 42 by the clamping components 43. The splash guard 41 prevents the debris generated during the cutting process from splashing everywhere, which may cause magnetic debris to be adsorbed on the surrounding device and affect the normal use of the device. At the same time, it can also prevent the sewage from the spray component 7 from splashing everywhere during use. A drain pipe 44 is fixedly connected to one end of the inner cavity of the splash guard 41.

[0026] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the clamping assembly 43 includes clamping plates 431 movably connected to both sides of the top of the mesh plate 42. A limiting plate 432 is fixedly connected to the top of the clamping plate 431. A connecting hole 433 is provided on one side of the top of the limiting plate 432. An adjusting screw 434 is threadedly connected to the inner cavity of the connecting hole 433. A fastening block 435 is fixedly connected to the bottom end of the adjusting screw 434.

[0027] Furthermore, such as Figure 2 and Figure 5 As shown, cylinders 45 are fixedly installed at both ends of the splash guard 41. The output end of the cylinder 45 passes through the splash guard 41 and is fixedly connected to the middle of one end of the clamping plate 431. When fixing the NdFeB magnetic material to be cut, it is first placed on the top of the mesh plate 42. The cylinder 45 is started, and the extended end of the cylinder 45 pushes the clamping plates 431 on both sides to move towards the middle. The clamping plates 431 on both sides clamp and fix the NdFeB magnetic material. Then, the adjusting screw 434 in the inner cavity of the connecting hole 433 is rotated, so that the fastening block 435 moves downward to reinforce the top of the NdFeB magnetic material and avoid the vibration generated during the cutting process, which may cause the NdFeB magnetic material to shift in position and affect the cutting effect.

[0028] Furthermore, such as Figure 3 and Figure 5 As shown, the bottom end of the drainage pipe 44 is inclined. The end of the drainage pipe 44 away from the splash shield 41 passes through the cutting table 1. The drainage pipe 44 is connected to the cutting groove 2. During the cutting process, the device will spray water through the spray component 7 to reduce the temperature generated during cutting. At the same time, it can wash away the debris generated during the cutting of the neodymium iron boron magnetic material. The wastewater generated by the spraying flows into the inner cavity of the cutting groove 2 through the mesh plate 42. The wastewater stored in the inner cavity of the cutting groove 2 is discharged and treated centrally through the drainage pipe 44. The inclined design of the bottom end of the drainage pipe 44 effectively improves the drainage efficiency.

[0029] Furthermore, such as Figure 1 and Figure 5 As shown, the spraying assembly 7 includes a fixing plate 71 sleeved on one side of the outer surface of the laser cutting equipment 6. Both sides of the bottom end of the fixing plate 71 are fixedly connected to connecting rings 72. The inner cavity of the connecting rings 72 is fixedly connected to a nozzle 73. The input end of the nozzle 73 is fixedly connected to a hose 74.

[0030] Furthermore, such as Figure 5 As shown, two nozzles 73 are located on the left and right sides of the laser cutting equipment 6, respectively. The nozzles 73 are set at an angle. The end of the hose 74 away from the nozzles 73 passes through the equipment frame 3 and is connected to the output end of the external water source equipment. During the use of the laser cutting equipment 6, the two angled nozzles 73 ensure that their output ends are always aligned with the cutting area of ​​the laser cutting equipment 6. Water is sprayed onto the cutting area through the nozzles 73 to cool down the cutting area of ​​the neodymium iron boron magnetic material, so as to avoid deformation or melting of the cutting edge caused by the high temperature generated during cutting. The spraying component 7 ensures the integrity of the appearance of the neodymium iron boron magnetic material after cutting.

[0031] Furthermore, such as Figure 5 and Figure 6 As shown, a rack 8 and a slider 9 are fixedly connected to the top two sides of the cutting table 1, respectively. A groove is provided at one end of the equipment frame 3, and a gear 10 is provided in the inner cavity of the groove. Slide grooves 11 are provided on both sides of the bottom end of the equipment frame 3.

[0032] Furthermore, such as Figure 5 and Figure 6 As shown, one of the slide grooves 11 is connected to the groove, the position of the gear 10 corresponds to the position of the rack 8, the outer surface of the gear 10 is meshed with the top of the rack 8, and the other slide groove 11 is slidably connected to the slider 9. During the cutting process, the rotation of the gear 10 drives the equipment frame 3 to move back and forth on the top of the cutting table 1. During the movement of the equipment frame 3, the two slide grooves 11 at the bottom slide on the top surfaces of the rack 8 and the slider 9 respectively, which effectively increases the stability of the equipment frame 3 during the movement.

[0033] Furthermore, such as Figure 5 and Figure 6 As shown, a drive device 12 is fixedly installed on the upper part of one end of the equipment frame 3, and a motor 13 is fixedly installed on the lower part of the other end of the equipment frame 3. The output end of the drive device 12 is fixedly connected to the linear guide rail 5, and the output end of the motor 13 is fixedly connected to the gear 10. The motor 13 drives the gear 10 to rotate, and the drive device 12 drives the linear guide rail 5 to move, thereby driving the laser cutting equipment 6 to move left and right on the linear guide rail 5.

[0034] The working principle of this invention is as follows: First, connect the hose 74 in the spray assembly 7 to the output end of the external water source equipment. Then, place the NdFeB magnetic material to be cut on the mesh plate 42. Next, start the cylinder 45. The extension end of the cylinder 45 pushes the clamping plates 431 on both sides to move continuously towards the middle, clamping and fixing the NdFeB magnetic material on the mesh plate 42. After fixing, rotate the adjusting screw 434 threaded in the limiting plate 432 to fix the fastening block 435 on the top of the NdFeB magnetic material. The top of the neodymium iron boron magnetic material is reinforced by fastening block 435. After fixing, drive device 12 and motor 13 are started. Drive device 12 drives linear guide rail 5, causing laser cutting device 6 to move left and right on linear guide rail 5. Motor 13 drives gear 10 to rotate. Through the rotation of gear 10 at the top of rack 8, the equipment frame 3 moves back and forth at the top of cutting table 1. During the movement of equipment frame 3, the two sliding grooves 11 at the bottom slide on the top surfaces of rack 8 and slider 9 respectively, effectively increasing the efficiency of cutting. To ensure the stability of the equipment frame 3 during movement and to guarantee that the laser cutting equipment 6 can move according to cutting requirements, the laser cutting equipment 6 emits a cutting laser to cut the neodymium iron boron magnetic material fixed on the mesh plate 42. During the cutting process, the splash guard 41 prevents debris generated during the cutting process from splashing everywhere, which could cause magnetic debris to adhere to the surrounding equipment and affect its normal use. The nozzle 73 continuously sprays water onto the cutting area to cool down the cutting area of ​​the neodymium iron boron magnetic material, preventing the high temperature generated during cutting from causing deformation or melting of the cutting edge. At the same time, it can also wash away the debris generated during cutting. The washed debris and wastewater flow into the inner cavity of the cutting groove 2 through the mesh plate 42. Since the inner cavity of the cutting groove 2 is connected to the drainage pipe 44, the debris and wastewater flowing into the inner cavity of the cutting groove 2 are centrally discharged through the drainage pipe 44. At the same time, during the spraying process of the nozzle 73, the splash guard 41 prevents wastewater from the spraying component 7 from splashing everywhere.
