Description

Technical Field

[0001] The utility model relates to the technical field of magnetic materials, in particular to a radiation magnetization device for a neodymium iron boron magnetic ring. Background Art

[0002] NdFeB magnetic rings are composed of neodymium, iron, and boron. When subjected to a magnetic field, the magnetization curve of NdFeB magnetic rings exhibits a distinct saturation magnetization, or hysteresis loop. This property is determined by two parameters: the residual magnetization and the coercive force. The magnetization curve exhibits extremely weak thermal history effects, meaning its magnetic properties do not change due to thermal loads. Furthermore, the magnetization curve is stable and retains its original shape after being milled into a ring. NdFeB magnetic rings have a very high saturation magnetization, reaching 1400-1500 mT. This allows them to store large amounts of energy in a small volume, resulting in a very high energy density.

[0003] Currently, this type of magnetizing device is limited in the outer diameter range of magnetic rings that can be processed, generally within 10 to 100 mm. This limits its application in magnetizing larger magnetic rings. During the magnetization process, if the magnetic field is unstable or the magnetization is uneven, it may have a negative impact on the magnetized material, such as affecting the material's stability or causing poor magnetization.

[0004] Therefore, we propose a radiation magnetization device for NdFeB magnetic ring to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a radiation magnetization device for a NdFeB magnetic ring to solve the problem of unstable or uneven magnetic field mentioned in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a radiation magnetization device for a NdFeB magnetic ring, comprising a chassis and a workbench, wherein the bottom of the workbench is fixedly connected to the upper surface of the chassis, the front of the chassis is fixedly connected to a control box, a control button is provided above the control box, and a magnetization mechanism is provided inside the workbench;

[0007] The magnetizing mechanism includes a magnetizing unit and a protection unit;

[0009] The protection unit includes a motor and a protection plate. The motor is arranged in the middle above the front of the workbench, and the protection plate is connected to the output end of the motor through a transfer bar.

[0010] Preferably, universal wheels are fixedly connected to the bottom of the chassis. By installing universal wheels, the entire radiation magnetization device can be more easily moved. When the working position needs to be changed or the equipment needs to be maintained, the device can be easily pushed, thereby improving the flexibility and convenience of the device.

[0011] Preferably, a magnetizing coil is disposed within the outer magnetizing ring, with the coil core at its center. This core is provided with an inner ring magnetizer and several outer ring magnetizers radiating outward from the coil core, thereby improving magnetization efficiency and uniformity. The inner and outer ring magnetizers facilitate the concentration and diffusion of the magnetic field, enabling the outer magnetizing ring to generate a stronger and more evenly distributed magnetic field, thereby enhancing the magnetization effect.

[0012] Preferably, there are four support rods, which are fixedly connected to the support plate to ensure the stability and firmness of the support plate. The cylinder and other components installed on the support plate can have sufficient supporting force when working, preventing equipment damage or working errors caused by unstable support.

[0013] Preferably, the width of the protective plate is equal to the width of the workbench. The design of the protective plate being equal to the width of the workbench can ensure that the workbench and the items thereon are completely shielded and protected during the magnetization process.

[0014] Preferably, the placement platform is arranged in the middle of the magnetized outer ring. Setting the placement platform in the middle of the magnetized outer ring can ensure that the NdFeB magnetic ring to be magnetized is located in the center of the magnetized outer ring.

[0015] Preferably, the pressing block corresponds to the placing table up and down. The design of the pressing block corresponding to the placing table up and down can ensure that during the magnetization process, the pressing block can accurately act on the NdFeB magnetic ring to be magnetized, fix the position of the magnetic ring, and prevent it from moving or flipping during the magnetization process, thereby ensuring the accuracy and stability of the magnetization.

[0027] The magnetizing mechanism includes a magnetizing unit;

[0028] The magnetizing unit includes a fixed block 101, a magnetizing outer ring 5, a placement table 6, cylinder one 601, cylinder two 602, an electrical box 9, a generator set 10, wire one 11, wire two 12, a support rod 13, a support plate 14, cylinder three 15, a connecting block 16 and a pressing block 17. The two ends of the fixed block 101 are fixedly connected to the left and right sides of the inside of the chassis 1, and cylinder one 601 and cylinder two 602 are fixedly connected to the upper surface of the fixed block 101. The fixed block 101 is used to fix cylinder one 601 and cylinder two 602 to ensure that they stably push the magnetizing outer ring 5. The output terminals of cylinder 1 (601) and cylinder 2 (602) are connected to the lower ends of the magnetizing outer ring (5). Inside the magnetizing outer ring (5) is a magnetizing coil, centered at the coil pole core. This core is equipped with an inner ring magnetizer, along with several outer ring magnetizers radiating outward from the coil pole core. The internal magnetizing coil and its associated magnetizers are key components of the magnetization process, generating a magnetic field that magnetizes the NdFeB magnetic ring. The bottom of the placement table (6) is fixedly connected to the middle of the upper surface of the chassis (1). The placement table (6) is positioned in the middle of the magnetizing outer ring (5), ensuring the magnetizer maintains its optimal position during the magnetization process. The front of the electrical box (9) is fixedly connected to the back of the chassis (1). A generator set (10) is located inside the chassis (1). Wires (11) and (12) are connected to the generator set (10). Wires (11) and (12) are connected to the positive and negative poles of the magnetizing outer ring (5), respectively, providing electrical energy and ensuring the power supply required for the magnetization process. The bottom of support rod 13 is fixedly connected to the upper surface of workbench 4, and the top of support rod 13 is connected to the lower surface of support plate 14. There are four support rods 13, and support rods 13 are fixedly connected to the four sides of support plate 14. Cylinder 3 15 is located in the middle below support plate 14. The output end of cylinder 3 15 is connected to connecting block 16, which is used to control the up and down movement of pressing block 17 to ensure that the magnetic ring is stably pressed during the magnetization process.

[0029] Based on the first embodiment, the magnetization mechanism further includes a protective unit, which includes a motor 8 and a protective plate 7. The motor 8 is located in the center of the upper front of the workbench 4. The protective plate 7 is connected to the output end of the motor 8 via a connecting strip. The width of the protective plate 7 is equal to the width of the workbench 4.

Its width is equal to the width of the workbench, ensuring a good shielding effect.

[0030] Working Principle: Place the NdFeB magnet ring to be magnetized on the placement table 6, ensuring it is centered within the magnetized outer ring 5. Using the control buttons on the control box 2, activate the generator set 10 and cylinders 1 (601) and 2 (602). Adjust the position of the magnetized outer ring 5. After confirming the correct position of the magnetized outer ring 5, activate the generator set 10. The magnetizing coil within the magnetized outer ring 5 generates a magnetic field, which magnetizes the ring through the inner and outer magnetizers. The magnetic field generated by the magnetized outer ring 5 magnetizes the ring. During the magnetization process, the motor 8 rotates the protective plate 7, shielding the workbench 4 and ensuring user safety. After magnetization is complete, the motor 8 drives the protective plate 7 to continue rotating, revealing the workbench 4. The user then operates cylinder 3 (15) using the control buttons to lift the push-button 17, simultaneously controlling cylinders 1 (601) and 2 (602) to lower the magnetized outer ring 5 and remove the magnetized ring.
