Production device for pressing, curing and linking neodymium-iron-boron magnet containing heavy rare earth

Abstract

The invention discloses a production device for pressing, curing and linking a neodymium-iron-boron magnet containing heavy rare earth. The device comprises a pressing table and a pressing device, thepressing device is mounted on one side of the upper end of the pressing table; when the air cylinder pushes the feeding bin to move at the upper end of the bottom film plate, connecting frames installed at the two ends of the feeding bin slide in inner cavities of the sliding grooves. The connecting frames move to drive the magnet to transversely move; when the magnet moves to the lower end of the vibration device; at the moment, the rotor in the power-on state can rotate, the rotor rotates to drive the disc installed at the eccentric position to rotate, the disc rotates to enable the vibration device to vibrate, vibration transmission enables the materials in the inner cavity of the film hole to be naturally laid flat under vibration, and therefore the die head is pressed downwards to bestressed evenly, and the bonding quality of the materials is improved.

Description

technical field [0001] The invention relates to the technical field of NdFeB magnet production equipment, in particular to a NdFeB magnet containing heavy rare earth pressing and solidifying linkage production device. Background technique [0002] Neodymium magnets, also known as NdFeB magnets, are tetragonal crystals formed of neodymium, iron, and boron. In 1982, Masato Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product of this kind of magnet is greater than that of samarium cobalt magnet, and it is the material with the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metals successfully developed the powder metallurgy method, and General Motors successfully developed the spin spray melting method, which can prepare NdFeB magnets. This kind of magnet is the second most magnetic permanent magnet after the absolute zero holmium magnet, and it is also the most commonly used rare earth magnet. NdFeB ...

Problems solved by technology

[0003] However, when the current NdFeB magnet is pressed and solidified, the powdery material needs to be fed into the mold first, and then solidified by pressing down the hydraulic cylinder. The powdery material in the mold cannot be automatically flattened in the mold. , it is easy to cause uneven force when the die head is pressed down and solidified, which affects the quality of the material when it is pressed and solidified, and after the material is solidified, the ejector device can only eject the material, but not the mold hole.
