Abstract

The invention discloses a powder screening device for magnet processing. The device comprises a base, wherein a bottom plate is supported in the base through first springs, a vibration motor is mounted in the middle of the lower end of the bottom plate, a screening base is arranged at the upper end of the bottom plate through supporting seats on the two sides, a screen is arranged at the bottom ofthe screening base, and a material distributing disc extending into the screening base is connected between supporting columns; and the bottom of a mounting base is movably connected with a driving rotating shaft driven by a servo motor through a connecting mechanism, the bottom of the driving rotating shaft is connected with a brush disc extending into the material distributing disc, the right side of the mounting base is further connected with a feeding box, and a crushing mechanism driven by the servo motor is further arranged in the feeding box. According to the screening device, under the rotating condition of the brush disc, neodymium iron boron powder is tiled, and the screening speed of the neodymium iron boron powder through material leaking holes is improved; and the screening efficiency of the neodymium iron boron powder is improved by two times of screening.

Description

technical field [0001] The invention relates to the technical field of magnet processing, in particular to a powder sieving device for magnet processing. Background technique [0002] NdFeB magnets can be divided into bonded NdFeB magnets and sintered NdFeB magnets. Bonding is actually injection molding, while sintering is vacuumized and formed by high temperature heating. NdFeB magnets have the most Strong magnetic permanent magnets, NdFeB permanent magnets need to screen the powder during processing to obtain magnets with good performance. [0003] The screening process of NdFeB powder is simple and cannot be screened multiple times. The screening effect of the powder sieving device is not good, and the falling speed of NdFeB powder in the screening process is slow, which further reduces the screening efficiency. For this reason, we have introduced a powder sieving device for magnet processing. Contents of the invention [0004] The object of the present invention is t...
