Description

Technical Field

[0001] The utility model relates to the technical field of preparation of oxidation-resistant NdFeB magnetic rings, in particular to a preparation device of oxidation-resistant NdFeB magnetic rings. Background Art

[0002] NdFeB magnetic ring is a commonly used magnetic material that can be used in a variety of modern electronic devices. Due to the high density of the pressed green body of NdFeB powder, the contact between particles is mechanical contact with low bonding strength. In order to further increase the density, improve the contact properties between powders, and increase the strength, so that the magnet has the microstructural characteristics of high permanent magnetic properties, the pressed green body needs to be heated to a temperature below the melting point of the powder basic phase, heat treated for a period of time, and then processed again by high-temperature quenching, tempering and other technical means.

[0003] After a series of treatments, the magnetic ring needs to be treated with antioxidant treatment. However, the iron element in the raw material of the magnetic ring will oxidize during the processing to form rust attached to the outside of the magnetic ring, and the magnetic ring cannot be treated with antioxidant treatment well. Secondly, when the magnetic ring is pickled, the pickling liquid cannot flow, and the treatment effect on the rust on the surface of the magnetic ring is poor and the treatment time is long. Finally, after the pickled magnetic ring is taken out of the pickling tank, the pickling liquid will adhere to the outer surface of the magnetic ring, and the drainage is slow. Therefore, in view of the above problems, an antioxidant NdFeB magnetic ring preparation device is proposed. Utility Model Content

[0025] A fixing frame 17 is fixedly connected to the outside of the pickling tank 1, a horizontally arranged fixing rod 18 is fixedly connected inside the fixing frame 17, an air supply tube 19 is fixedly connected to the top of the fixing rod 18, and a fan 20 is fixedly connected inside the air supply tube 19; the rotating shaft 5 and the pickling tank 1 are rotatably connected; the water pump 14 is fixed at the bottom end of the pickling tank 1; the water outlet nozzle 16 and the pickling tank 1 are fixedly connected, and the water outlet nozzle 16 is located at the upper center of the side of the pickling tank 1.

[0026] Working process: The device is arranged in a ventilated environment, and the electrical equipment of the device is powered by an external power supply. There is a certain amount of pickling liquid in the pickling tank 1. Before the anti-oxidation treatment of the magnetic ring, the rust on the surface of the magnetic ring needs to be removed. The magnetic ring is placed in the pickling tank 1 through the handling device, and the motor 3, the water pump 14 and the fan 20 are started. The motor 3 on the outside of the bracket 2 drives the rotating shaft 5 to rotate through the coupling 4. There are blades 6 on the outside of the rotating shaft 5. Under the action of the motor 3, the blades 6 rotate to irradiate the acid in the pickling tank 1. The washing liquid forms a stirring effect, and the stirred pickling liquid flows rapidly in the pickling tank 1 to flush and pickle the magnetic ring. There is a water outlet pipe 7 at the bottom of the pickling tank 1, and a valve 8 is fixed in the middle of the water outlet pipe 7. There is a filter tank 9 at the bottom of the water outlet pipe 7. A plugging cover 10 is threadedly connected to one end of the filter tank 9. A sealing ring 11 is on the outside of the plugging cover 10. When the plugging cover 10 and the filter tank 9 are connected, the sealing ring 11 seals the connection to prevent leakage of the pickling liquid. There is also a threaded connection inside the filter tank 9. The filter screen 12 is connected to the pickling liquid, and the filter screen 12 can filter the pickling liquid to remove impurities and rust blocks contained in the pickling liquid. The filtered pickling liquid enters the water pump 14 through the connecting pipe 13. After the water pump 14 is pressurized, the pickling liquid reaches the water outlet nozzle 16 from the return pipe 15, and then sprays out and enters the pickling tank 1. The sprayed pickling liquid has a flushing effect on the magnetic ring, which can impact the rust and accelerate the shedding of the rust. When the magnetic ring is processed in the pickling tank 1, the handling device removes the magnetic ring in the pickling liquid from the pickling tank 1. The magnetic ring is moved out of the pickling pool 1 and stays at a distance above the pickling pool 1 for draining. There is also a fixing frame 17 on the outside of the pickling pool 1, and a fixing rod 18 is horizontally placed in the fixing frame 17. The air supply tube 19 is fixed above the fixing rod 18 through its own fixing device, and the fan 20 is fixed inside the air supply tube 19. When the magnetic ring is draining, the fan 20 runs at a high speed to make the air flow quickly in the air supply tube 19. The flowing air can dry the magnetic ring, thereby reducing the time of the entire pickling process and reducing the production cost.
