- Rare earth magnets are permanent magnets made from rare earth elements, and neodymium magnets, samarium cobalt magnets, praseodymium magnets and the like have been put into practical use.
- the surface of a rare earth magnet is coated with a plating depending on its use, and in order to use the coated rare earth magnet again as a magnet raw material, it is necessary to remove the plating as a pretreatment. At this time, it is important that the plating does not remain on the magnet surface and that only the plating is peeled off without reducing the weight of the magnet itself.

- the magnet fixing device 22 includes a magnet 221 as a fixing portion for fixing the magnet 1 so that a plurality of plating-coated rare earth magnets 1 can be fixed on the same circumference. Since the plating-coated rare earth magnet 1 is mainly composed of iron, the magnet 1 can be fixed by the magnetic force of the magnet 241. In addition to the magnet, any method may be used for fixing the plating-coated rare earth magnet 1 as long as it does not cover the surface facing the abrasive projection port 21 such as fixing by a suction cup or suction by suction of air. I do not care.
- the apparatus used for the plating peeling process is not a magnet fixing apparatus rotating type, but an abrasive projection apparatus rotating type in which the plating coated rare earth magnet 1 is fixed and the abrasive projecting apparatus is rotated by a motor as shown in FIG.
- the plating peeling apparatus 2 may be used.
- the abrasive can be uniformly projected onto the surfaces (1) to (6), the abrasive can be projected onto each surface without excess or deficiency. Thereby, without reducing the weight of the magnets to be recovered, the plating can be peeled off in a short time and reused for magnet production.
- the plating stripping apparatus 2 will be described with reference to FIG.
- the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
- the abrasive is projected by using two abrasive projection ports of the abrasive projection device 21.
- the position of the abrasive projection port was set at a slight distance so that the abrasive was projected onto the entire plating-coated rare earth magnet 1.
- the two abrasive projection ports are directed in the same direction, but the directions of the respective abrasive projection ports may be different. In this case, it is necessary to project the abrasive at different timings so that the airflows from the abrasive projection device 21 do not interfere with each other.
- the apparatus used for the plating stripping process is not a magnet fixing apparatus rotating type, but the plating-coated rare earth magnet 1 is fixed as shown in FIG. 10 and the abrasive projection apparatus is rotated by a motor.
- An abrasive projection apparatus rotating type plating peeling apparatus 2 may be used.
- plating stripping treatment was performed, and the stripping completion time and stripping state were observed.
- the plating stripping apparatus strips the plating under the same conditions as in Example 1 except that two abrasive projection ports of the abrasive projection apparatus 21 are used to simultaneously project the abrasive. Processed. The position of the abrasive projection port was set so that the direction in which the two abrasive projection ports faced was another direction (vertical). [Comparative Example 2]
- the plated coated rare earth magnet 1 passes between the two surfaces having the largest area among the six surfaces of the magnet, and the long side among the four sides of the two surfaces.
- the abrasive projection port is set so that the abrasive projection direction is perpendicular to the rotation axis, and the other conditions are the same as in the first embodiment.
- the plating peeling process was performed.
- Example 1 and 2 first, the surface (1) and (2) of the plating-coated rare earth magnet 1 were peeled using the magnet fixing device 22, and the plating peeling of the surfaces (1) and (2) was completed. This was confirmed by observation of the magnet appearance. Next, peeling of the surfaces (3) and (4) of the plating-coated rare earth magnet 1 was performed, and it was confirmed by observation of the magnet appearance that plating peeling of the surfaces (3) and (4) was completed. Next, peeling treatment of the surfaces (5) and (6) of the plated coated rare earth magnet 1 is performed, and it is confirmed by observing the appearance of the magnet that the plating peeling of the surfaces (5) and (6) is completed, and the plating peeling treatment is completed. did.
- Example 1 the time for projecting the abrasive per one piece of the plating-coated rare earth magnet 1 was 28.3 seconds in total, and when the appearance was observed, the plating was completely peeled off.
- the shape of the magnet body was the same as before plating peeling, and no chipping or the like was observed.
- Example 2 the time for projecting the abrasive per one piece of the plating-coated rare earth magnet 1 was 14.9 seconds in total, and when the appearance was observed, the plating was completely peeled off.
- the shape of the magnet body was the same as before plating peeling, and no chipping or the like was observed. In this way, by increasing the number of projection openings and peeling the plating one surface at a time, it is possible to shorten the time for the plating peeling process.
- Comparative Example 1 when the magnet fixing device 22 is used, it is possible to project the abrasive onto the surface (3) or (4) simultaneously with the surface (1) or (2).
- the airflow of the abrasive projections interferes with each other and the plating cannot be peeled off well, making it difficult to completely peel off the plating. Therefore, even if projection of the abrasive was continued for 30 seconds or more, the plating was not completely peeled off, and the plating peeling process was terminated halfway. The plating remained at the end of the magnet. Moreover, the hollow was seen in the part from which plating was peeled, and it was confirmed that the magnet main body was shaved with the projection material and the weight reduced.
