Description

Technical Field

[0001] This invention belongs to the field of magnetization technology, and particularly relates to a magnetization device for a radial quadrupole NdFe ring. Background Technology

[0002] Radial quadrupole NdFe ring magnetization equipment is mainly used to produce permanent magnet materials, especially in the manufacture of high-performance NdFeB magnetic rings. NdFeB (neodymium iron boron) is a permanent magnet material widely used in various equipment, such as motors, generators, and sensors. The magnetization equipment ensures the uniformity and strength of the ring magnetic field, thereby producing permanent magnet materials with excellent performance.

[0003] The structure of the magnetizing device for radial quadrupole NdFe rings includes a magnetizing cylinder and a sliding cylinder. The magnetizing device for radial quadrupole NdFe rings mainly utilizes four electromagnetic coils to generate a uniform radial magnetic field. Through current control and temperature regulation, it achieves efficient magnetization of NdFe rings and enhances their magnetic properties.

[0004] In existing technologies, some ring magnetization devices simply place the ring, meaning that the ring body is freely placed during the magnetization process by the action of a magnetic field. This can lead to positional shifts and vibrations, resulting in uneven magnetic field distribution during magnetization and affecting the magnetization effect of the ring body. This instability directly affects the magnetization quality. Therefore, a radial quadrupole NdFe ring magnetization device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a magnetizing device for a radial four-pole NdFe ring, aiming to solve the technical problem in the prior art of not setting a fixing mechanism for the ring body during the magnetization process.

A heat dissipation and dust prevention mechanism 18 is fixedly connected to the top of the fixing mechanism 5. The heat dissipation and dust prevention mechanism 18 is used to ensure that the device can effectively dissipate heat during long-term operation and prevent dust from entering the device, thereby improving the heat dissipation efficiency of the device.

[0037] The fixed mechanism 5 includes a magnetizing worktable 6, the bottom of which is fixedly connected to the top of the base plate 1. The magnetizing worktable 6 is the equipment carrier for the magnetizing cylinder 7. The top of the magnetizing worktable 6 is fixedly connected to the magnetizing cylinder 7, which is the output component of the magnetizing equipment and plays the role of guiding the magnetic field flow and concentrating the magnetic force. The top of the magnetizing cylinder 7 is slidably connected to a sliding cylinder 9. The top of the sliding cylinder 9 is fixedly connected to a ring body 8. The sliding cylinder 9 allows the ring body 8 to slide horizontally within the magnetizing cylinder 7. The interior of the sliding cylinder 9 is fixedly connected to a drive assembly, which is the power source of the fixed mechanism 5. The drive assembly includes a motor 10, the exterior of which is fixedly connected to the interior of the sliding cylinder 9. The motor 10 is used to output power. The output end of the motor 10 is fixedly connected to an output shaft 11, which is used to output the power of the motor 10. The exterior of the output shaft 11 is fixedly connected to the interior of a pinion 12. The top of the sliding cylinder 9 is rotatably connected to a transmission assembly.

[0038] The transmission assembly is used to transmit power to the drive assembly. The transmission assembly includes a pinion 12. The motor drives the pinion 12 to rotate via the output shaft 11. The bottom of the pinion 12 is rotatably connected to the top of the ring body 8. A large gear 13 is rotatably connected to the top of the ring body 8. The pinion 12 and the large gear 13 are meshed together. The rotation of the pinion 12 and the meshing with the large gear 13 drive the rotation of the large gear 13. Multiple sliding grooves 14 are provided inside the large gear 13. Multiple sliding rods 15 are slidably connected to the transmission assembly. The outer surfaces of the sliding rods 15... The sliding rod 15 is dynamically connected inside the sliding groove 14. When the large gear 13 rotates, the sliding rod 15 slides in the sliding groove 14 opened inside the large gear 13.

[0039] Reference Figures 1 to 3 The heat dissipation and dust prevention mechanism 18 includes two side grilles 19. The bottom of the two side grilles 19 is fixedly connected to the top of the magnetization workbench 6. The side grilles 19 and 21 work together to enclose the magnetization part, blowing away dust while the fan 20 dissipates heat, preventing dust from sticking to the ring body 8. Multiple fans 20 are fixedly connected inside the two side grilles 19. The function of the fans 20 is to remove the heat generated by the equipment through airflow, keeping the temperature of the equipment stable during the magnetization process. The top of the magnetization workbench 6 is fixedly connected to two side grilles 21. The two side grilles 21 are fixedly connected to the outside of the fan 20. The two side grilles 21 and the side grille 19 work together to enclose and prevent dust. The top of the side grille 19 is fixedly connected to a breathable dustproof plate 22. The bottom of the breathable dustproof plate 22 is fixedly connected to the top of the side grille 21. The breathable dustproof plate 22 is used to filter dust and impurities that enter the equipment, ensuring the long-term stability and accuracy of the equipment. Multiple heat sinks 23 are fixedly connected to both sides of the magnetized cylinder 7. The heat sinks 23 are usually fixed to both sides of the magnetized cylinder 7 to enhance the heat dissipation effect of the magnetized cylinder 7.

[0040] Working principle: The magnetizing host 2 generates a strong magnetic field, which transmits electrical energy to the pressing device 4 through the connecting line 3. Then, the pressing device 4 drives the ring body 8 to press down, so that the ring body 8 and the sliding cylinder 9 slide into the magnetizing cylinder 7 to prepare for magnetization. Inside the fixing mechanism 5, the motor 10 is the core of the drive component, which outputs power to the output shaft 11 to drive the small gear 12 to rotate. The small gear 12 meshes with the large gear 13, so that the large gear 13 starts to rotate. As the large gear 13 rotates, the multiple sliding grooves 14 inside the large gear 13 drive the sliding rod 15 to slide in the sliding grooves 14. The sliding fixing strip 16 connected to the top of the sliding rod 15 slides in the fixing shell 17 during the sliding process, thereby fixing the ring body 8 and ensuring the stability of the ring body 8 during the magnetization process.

[0041] During equipment operation, the heat dissipation and dust prevention mechanism 18 works synchronously. The fan 20 removes the heat generated by the equipment through airflow, keeping the equipment temperature stable. The side grilles 19 and 21 work together to block the dust when the fan 20 dissipates heat, preventing dust from adhering to the main body 8 of the ring. The breathable dustproof plate 22 filters the dust and impurities that enter the equipment. The heat sinks 23 on both sides of the magnetized cylinder 7 further enhance the heat dissipation effect of the magnetized cylinder 7, ensuring the long-term stable operation of the equipment and completing the magnetization of the radial four-pole NdFe ring.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
