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, not the die hole. Clean up residual powder

Abstract

The invention discloses a production device for pressing and solidifying NdFeB magnets containing heavy rare earths, which includes a pressing table and a pressing device. The pressing device is installed on one side of the upper end of the pressing table. When the upper end of the plate moves, the connecting frame installed at both ends of the feeding bin slides in the inner cavity of the chute, and the moving of the connecting frame drives the magnet to move laterally. When the magnet moves to the lower end of the vibrating device, the rotor in the electrified state can rotate at this time , the rotor rotates to drive the disc installed at the eccentric position to rotate, the disc rotates to vibrate the vibrating device, and the vibration transmission enables the material in the inner cavity of the membrane hole to be flattened naturally under vibration, so that the pressure on the die head is averaged, thus Improve the bonding quality of materials.

Description

technical field [0001] The invention relates to the technical field of NdFeB magnet production equipment, in particular to a production device for pressing and solidifying NdFeB magnets containing heavy rare earths. 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 magnet is greater than that of the samarium cobalt magnet, and it was 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 smelting method, which was able to 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. Nd...
