Description

[0002] Magnetic materials are materials that can respond to magnetic fields in a certain way. According to the strength of the magnetism exhibited by a material in an external magnetic field, they can be divided into diamagnetic materials, paramagnetic materials, ferromagnetic materials, antiferromagnetic materials, and ferrimagnetic materials.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] The following is in conjunction with the appendix Figure 1 Detailed description of a magnetic material manufacturing process, which includes the following steps:

[0032] Step 1: Sinter and grind the raw materials to prepare anisotropic and isotropic products;

[0033] Step 2: Perform wet pressing magnetic field forming and drying powdering treatment on the anisotropic products, and then perform dry pressing magnetic field forming treatment on the dried powdering materials;

[0034] Step 3: Drying, granulation, and dry pressing are performed on the isotropic products;

[0035] Step 4: Perform secondary sintering on the materials from Steps 2 and 3, and add the sintered materials into the cleaning and grinding device to complete the cleaning and grinding process.

[0036] Step 5: Magnetize the cleaned and polished material to complete the production of magnetic materials.

[0037] The following is in conjunction with the appendix Figure 2 , 4 -8 and 10 provide detailed descriptions. The cleaning device includes a cleaning barrel 101, a supporting frame plate 102, multiple sliding plates 103, multiple threaded cavities 104, multiple sliding rods 105, multiple sets of multiple hollow magnets 106, and multiple cleaning round plates 107. The supporting frame plate 102 is slidably connected inside the cleaning barrel 101. The multiple sliding plates 103 are evenly slidably connected to the supporting frame plate 102 through multiple grooves. The multiple threaded cavities 104 are respectively fixedly connected to the multiple sliding plates 103 by welding. The multiple sliding rods 105 are respectively fixedly connected to the multiple threaded cavities 104 by threads. The multiple sets of multiple hollow magnets 106 are respectively slidably connected to the multiple sliding rods 105. The multiple cleaning round plates 107 are all slidably connected inside the cleaning barrel 101. The multiple sets of multiple hollow magnets 106 are respectively placed at intervals and in contact with the multiple cleaning round plates 107.

[0038] Furthermore, the inner wall of the cleaning barrel 101 is provided with a polishing layer, which can be used to polish the outer surfaces of multiple sets of hollow magnets 106. The cleaning barrel 101 is used to clean and polish multiple sets of hollow magnets 106 after processing. The supporting frame plate 102 serves as a load-bearing and connecting element. The supporting frame plate 102 is provided with multiple sliding grooves, which provide sliding space for multiple sliding plates 103, thus limiting the sliding of the multiple sliding plates 103. This ensures that the multiple sliding plates 103 can only slide along the directions of the multiple sliding grooves on the supporting frame plate 102. The multiple sliding plates 103 can support multiple... The threaded cavity 104 provides a fixed space, and multiple threaded cavities 104 can provide a fixed space for multiple sliding rods 105. Depending on the diameter of the hollow portion of the multiple sets of hollow magnets 106, different sliding rods 105 and multiple grinding discs 107 are used. A grinding layer is provided on the outer surface of each sliding rod 105, which allows for grinding of the inner circular surfaces of the multiple sets of hollow magnets 106. The multiple sliding rods 105 provide a connection space for the multiple sets of hollow magnets 106, allowing the hollow portions of the multiple sets of hollow magnets 106 to slide smoothly connected to the multiple sliding rods 105. Figure 5 , 6As shown in section 10, multiple sets of hollow magnets 106 are placed alternately with multiple polishing discs 107. Both the upper and lower surfaces of the polishing discs 107 are provided with polishing layers. The multiple polishing discs 107 contact the upper and lower surfaces of the multiple sets of hollow magnets 106. The multiple polishing discs 107 can be used to clean and polish the upper and lower surfaces of the multiple sets of hollow magnets 106. The multiple polishing discs 107 slide with the polishing barrel 101 via keys and keyways, achieving a limiting effect on the multiple polishing discs 107 and ensuring that the multiple polishing discs 107 and the polishing barrel 101 are relatively fixed and will not rotate. When the multiple sets of hollow magnets 106 and the multiple polishing discs 107 are respectively connected to the multiple sliding rods 105 and the polishing barrel 101, the bearing... When the support frame 102 rotates, the multiple sets of hollow magnets 106 will contact the polishing layer on the inner wall of the polishing barrel 101 and rotate, thus completing the polishing of the outer surface of the multiple sets of hollow magnets 106. When the multiple sets of hollow magnets 106 rotate, the multiple sliding rods 105 can be used to polish the inner diameter surface of the multiple sets of hollow magnets 106. When the multiple sets of hollow magnets 106 rotate, they will contact the multiple polishing discs 107, and the multiple polishing discs 107 can be used to polish the upper and lower surfaces of the multiple sets of hollow magnets 106, thereby completing the all-round cleaning and polishing of the multiple sets of hollow magnets 106, ensuring that the surface of the multiple sets of hollow magnets 106 is smooth and clean.

[0039] The following is in conjunction with the appendix Figure 2 , 4 -7 and 9 provide detailed descriptions. The cleaning device also includes multiple transverse lead screws 201 and multiple bevel gears I202. The multiple transverse lead screws 201 are uniformly rotatably connected to the support frame plate 102 through round holes. Multiple sliding plates 103 are respectively connected to the multiple transverse lead screws 201 through threaded transmission. The multiple bevel gears I202 are respectively fixedly connected to the inner ends of the multiple transverse lead screws 201 by welding.

[0040] Furthermore, the rotation of multiple transverse lead screws 201 can drive multiple sliding plates 103 to slide on the support frame plate 102, thereby changing the position of multiple sliding plates 103 and ultimately changing the position of multiple sets of hollow magnets 106, ensuring that multiple sets of hollow magnets 106 are in contact with the inner wall of the cleaning barrel 101. At this time, when the rotation of the support frame plate 102 drives the multiple sets of hollow magnets 106 to rotate, the cleaning barrel 101 can be used to polish the outer surface of the multiple sets of hollow magnets 106.

[0041] According to the instruction manual Figure 2 , 4Sections -7 and 9 provide detailed descriptions. The grinding device further includes an adapter 301, a connecting rod 302, a bevel gear II 303, and a clamping bolt 304. The adapter 301 is fixedly connected to the support frame plate 102 by welding. The connecting rod 302 is rotatably connected to the adapter 301 through a round hole. The bevel gear II 303 is fixedly connected to the bottom of the connecting rod 302 by welding. Multiple bevel gears I 202 are meshed and connected to the bevel gear II 303. The clamping bolt 304 is threadedly connected to the adapter 301. The connecting rod 302 is in contact with the clamping bolt 304.

[0042] Furthermore, the adapter 301 provides space for the linkage 302 to rotate, and the linkage 302 can drive the bevel gear II 303 to rotate. When the bevel gear II 303 rotates, it will simultaneously drive multiple bevel gears I202 to rotate, thereby simultaneously adjusting the positions of multiple sets of hollow magnets 106. This ensures that multiple sets of hollow magnets 106 can simultaneously contact the inner wall of the cleaning barrel 101. The clamping bolts 304 can be used to fix the linkage 302, preventing the linkage 302 from rotating during the cleaning and polishing of multiple sets of hollow magnets 106, thus changing the positions of multiple sets of hollow magnets 106. In this way, multiple sets of hollow magnets 106 will not be able to be polished by the inner wall of the cleaning barrel 101.

[0043] According to the instruction manual Figure 2 and 4 -8 Detailed description: The cleaning device further includes a bottom support circular plate 401 and multiple limiting sliding columns 402. The bottom support circular plate 401 is rotatably connected to the cleaning barrel 101 through a circular hole. The multiple limiting sliding columns 402 are all fixedly connected to the bottom support circular plate 401 by welding. The supporting frame plate 102 and the multiple limiting sliding columns 402 are slidably connected through multiple circular holes.

[0044] Furthermore, the bottom support plate 401 can provide a fixed space for multiple limiting slide columns 402. When the bottom support plate 401 rotates, the multiple limiting slide columns 402 will drive the supporting frame plate 102 to rotate, thereby driving multiple sets of hollow magnets 106 to rotate, ensuring that multiple sets of hollow magnets 106 can be cleaned and polished evenly.

[0045] According to the instruction manual Figure 2 and 4 -8 Detailed description: The cleaning device also includes a telescopic rod 501 and a linkage frame 502. The telescopic rod 501 is fixedly connected to the bottom support circular plate 401 through a flange plate, and the linkage frame 502 is fixedly connected to the telescopic rod 501 through a flange plate. The support frame plate 102 and the linkage frame 502 are fixedly connected by welding.

[0046] Furthermore, when the telescopic rod 501 extends or retracts, it will drive the support frame plate 102 to rise or fall through the linkage frame 502, thereby changing the height of the support frame plate 102. When multiple sets of hollow magnets 106 are placed on multiple sliding rods 105, the height of the support frame plate 102 can be adjusted using the telescopic rod 501 so that the telescopic rod 501 is at its highest point. This makes it convenient to place multiple sets of hollow magnets 106 on multiple sliding rods 105.

[0047] According to the instruction manual Figure 2-8 In detail, the cleaning device also includes a central shaft 601, multiple horizontal fixing plates 602 and a liquid storage tank 603. The central shaft 601 is fixedly connected to the bottom support circular plate 401 by welding. The multiple horizontal fixing plates 602 are uniformly fixedly connected to the cleaning tank 101 by welding. The liquid storage tank 603 is fixedly connected to the multiple horizontal fixing plates 602 by welding.

[0048] Furthermore, the central shaft 601 can drive the bottom support plate 401 to rotate, while multiple horizontal fixing plates 602 can provide a fixed space for the liquid storage tank 603. The liquid storage tank 603 stores cleaning fluid, which will enter the cleaning tank 101. The cleaning fluid in the liquid storage tank 603 can be used to soak multiple sets of hollow magnets 106, thus completing the cleaning process of multiple sets of hollow magnets 106. A drain pipe with a valve is provided at the bottom of the liquid storage tank 603 to facilitate the discharge of the cleaning fluid in the liquid storage tank 603.

[0049] According to the instruction manual Figure 2 and 3 In detail, the cleaning device further includes a fixed support cavity 701 and multiple support legs 702. The fixed support cavity 701 is fixedly connected to the liquid storage tank 603 by welding, and the multiple support legs 702 are evenly fixedly connected to the bottom of the fixed support cavity 701 by welding.

[0050] Furthermore, the fixed support cavity 701 can be used to fix the liquid storage tank 603, and multiple support legs 702 can be used to fix the fixed support cavity 701, so that the device can be placed stably on the ground to complete the cleaning and polishing of multiple sets of hollow magnets 106.

[0051] According to the instruction manual Figure 2 and 3 In detail, the cleaning device also includes a geared motor 801, which is fixedly connected to the liquid storage tank 603 via a flange plate, and the central shaft 601 is fixedly connected to the output shaft of the geared motor 801 by welding.

[0052] Furthermore, after starting the geared motor 801, the central shaft 601 will rotate, and the rotating central shaft 601 will drive the bottom support plate 401 to rotate.

[0053] According to the instruction manual Figure 2 and 4 In detail, the cleaning device also includes a shielding cover 901 and multiple height limiting screws 902. The shielding cover 901 is fixedly connected to the cleaning barrel 101 by threads, and the multiple height limiting screws 902 are all connected to the shielding cover 901 by threads. The cleaning circular plate 107 located above is in contact with the multiple height limiting screws 902.

[0054] Furthermore, the cover 901 can be used to cover and seal the opening above the grinding barrel 101, while multiple height limiting screws 902 can be used to limit the grinding disc 107 located above, preventing multiple sets of hollow magnets 106 and multiple grinding discs 107 from moving up and down inside the grinding barrel 101.
