[0002] Materials that can respond to magnetic fields in some way are called magnetic materials. According to the strength of the magnetism exhibited by the material in the external magnetic field, it can be divided into diamagnetic materials, paramagnetic materials, ferromagnetic materials, antiferromagnetic materials and ferrimagnetic materials. Most materials are diamagnetic or paramagnetic, and they react weakly to external magnetic fields. Ferromagnetic materials and ferrimagnetic materials are strong magnetic materials, and the magnetic materials usually referred to are strong magnetic materials. For magnetic materials, magnetization curves and hysteresis loops are characteristic curves that reflect their basic magnetic properties. Ferromagnetic materials are generally Fe, Co and Ni elements and their alloys, rare earth elements and their alloys, and some Mn compounds.

[0032] like Figure 1-9 As shown, the magnetic material processing device is described in detail:

[0033] A magnetic material processing device comprises a base frame 101, a support frame 102 is fixed in the middle of the base frame 101, a fixed ring 103 is fixed at the upper end of the support frame 102, a rotating ring 201 rotates inside the fixed ring 103, a driving shaft 202 rotates at one end of the inner side of the rotating ring 201, two track frames 203 are symmetrically arranged on the inner wall of the rotating ring 201 about the driving shaft 202, sliding frames 204 are slidably arranged on the two track frames 203, tensioning shafts 205 are rotated on the two sliding frames 204, grinding belts 207 are sleeved on the two tensioning shafts 205 and the driving shaft 202, and tension springs 206 are arranged between the rotating rings 201 at the opposite ends of the two sliding frames 204 and the driving shaft 202 to tension the grinding belt 207, and a transmission ring 208 is arranged at one end of the rotating ring 201.

[0034] The base frame 101 is used to support the entire device. When in use, the magnetic rod to be polished is inserted into the rotating ring 201, and the magnetic rod is pressed against the polishing belt 207 between the two tensioning shafts 205 in the direction of the driving shaft 202; after the magnetic rod to be polished is coaxial with the rotating ring 201, the transmission ring 208 is driven by the first motor installed on the base frame 101, so that the transmission ring 208 drives the rotating ring 201 to rotate in the fixed ring 103, thereby driving the polishing belt 207 to rotate around the magnetic rod, and the outer surface of the magnetic rod is polished through the contact between the polishing belt 207 and the magnetic rod; then the magnetic rod is pushed to move axially, so that the magnetic rod slowly penetrates the rotating ring 201, thereby forming a complete polishing of the outer surface of the magnetic rod. This polishing method only needs to control the magnetic rod to be in a coaxial state with the rotating ring 201 and penetrate the rotating ring 201, so as to complete the overall polishing of the outer surface of the magnetic rod, which is simple to operate and has high polishing efficiency.

[0035] Among them, through two tension springs 206, the sliding frame 204 is pulled on the track frame 203 to move away from the driving shaft 202, thereby forming a tension on the grinding belt 207. When grinding, the magnetic rod is coaxial with the rotating ring 201, and the elastic force of the tension spring 206 will pull the grinding belt 207 between the two tensioning shafts 205 to surround the magnetic rod away from the driving shaft 202, ensuring the contact between the grinding belt 207 and the magnetic rod. At the same time, through the elastic force of the tension spring 206, the device can adapt to magnetic rods of different diameters.

[0036] Further:

[0037] The fixing ring 103 is coaxially fixed with a gear ring 104 at the end away from the transmission ring 208 , and one end of the driving shaft 202 is meshed and transmission-connected with the gear ring 104 .

[0038] When the rotating ring 201 rotates in the fixed ring 103 for grinding, the rotating ring 201 simultaneously drives the driving shaft 202 to rotate, and then the driving shaft 202 and the gear ring 104 move relative to each other, so that the driving shaft 202 rotates around its own axis, and then drives the grinding belt 207 to rotate, so that the grinding belt 207 rotates with the rotating ring 201, and at the same time, moves circumferentially on the two tensioning shafts 205 and the driving shaft 202, and further moves relative to the magnetic rod, thereby improving the grinding efficiency.

[0039] like Figure 3-6 As shown:

[0040] The gear ring 104 has a ring cover 107 extending toward the fixed ring 103 end, and the ring cover 107 is sleeved on the rotating ring 201. The front side of the gear ring 104 and the rear side of the transmission ring 208 are fixed with pressure rings 301, and cover cloths 302 are fixed inside the two pressure rings 301. An elastic ring 303 is provided in the center of the cover cloth 302.

[0041] By setting the ring cover 107, a connection is formed between the rotating ring 201 and the gear ring 104, thereby forming a closed circular tube cavity between the transmission ring 208 and the gear ring 104; at the same time, due to the elastic force of the elastic ring 303, it will be tightened around the magnetic rod, so that the magnetic rod in the grinding state will be partially blocked in the closed circular tube cavity through the two cover cloths 302, thereby preventing the dust generated by the grinding from floating around and affecting the environment.

[0042] like Figure 3 and 7 As shown:

[0043] The end of the rotating ring 201 away from the driving shaft 202 is provided with a leakage hole 209 .

[0044] The support frame 102 is provided with a drawer groove 108 , and a drawer 401 slides in the drawer groove 108 .

[0045] A pull pin 402 is provided on the side of the drawer 401 .

[0046] As the grinding continues, the dust generated by the grinding will gradually increase. Then, by setting the leakage hole 209, the dust in the closed circular tube cavity can be discharged, and by setting the drawer 401, the dust discharged from the leakage hole 209 is collected and collected, and the drawer 401 is pulled out of the drawer groove 108 by the pull pin 402, so that the dust in the drawer 401 is centrally processed.

[0047] like Figure 1-3 , as shown in 8:

[0048] Frames 105 are fixed at both the front and rear ends of the base frame 101. Three through holes 106 are evenly arranged on each frame 105 in the circumferential direction. A sliding rod 504 slides in each through hole 106. Each sliding rod 504 is provided with a limit frame near the axial end of the fixing ring 103. A spring 505 is provided between the limit frame and the frame 105, so that the three limit frames in each frame 105 are pressed against each other at the axis of the fixing ring 103.

[0049] The limiting frame includes a T-shaped frame 501 fixed to one end of a sliding rod 504 , and conveying wheels 502 are rotatably arranged at the three ends of the T-shaped frame 501 , and conveying belts 503 are sleeved on the three conveying wheels 502 .

[0050] The elastic force of the spring 505 can push the T-shaped frame 501 to drive the conveyor belt 503 to move in the axial direction of the fixed ring 103. Then, by setting three T-shaped frames 501 in each frame 105, the magnetic rod penetrating the frame 105 can be pressed against the center of the frame 105, that is, the magnetic rod and the fixed ring 103 are coaxially limited. By the second motor installed on the T-shaped frame 501, one of the conveying wheels 502 is driven to drive the conveyor belt 503 to rotate, thereby forming the conveyance of the magnetic rod, and achieving the purpose of automatically supplying the magnetic rod;

[0051] Moreover, by arranging the two frames 105 at the front and rear ends of the rotating ring 201 respectively, the magnetic rods can be transported alternately, thereby preventing the magnetic rods from being unable to move further and passing through the rotating ring 201 after being separated from the conveyor belt 503 on one side.

[0052] like Figure 1-9 As shown:

[0053] A processing method using the processing device includes:

[0054] S1, insert the magnetic bar to be polished into the rotating ring 201, and press the polishing belt 207 between the two tensioning shafts 205 toward the driving shaft 202;

[0055] S2, after controlling the magnetic rod to be polished to be coaxial with the rotating ring 201, the transmission rotating ring 201 rotates, thereby driving the polishing belt 207 to rotate around the magnetic rod, thereby polishing the outer surface of the magnetic rod;

[0056] S3. Push the magnetic bar axially to move, so as to completely polish the outer surface of the magnetic bar.

[0057] Further:

[0058] A magnetic material is a cylindrical magnetic bar with a smooth outer surface.
