Abstract

The invention discloses a strong magnetic powder forming device and method. The strong magnetic powder forming device comprises a frame body, a cylinder, a lower mold, an upper mold, a first mountingframe, a first driving device, a second mounting frame, a storage hopper, a second driving device, a third driving device, a feeding hopper, a stirring mechanism and a feeding mechanism. The device isreasonable in design and easy to operate, the cylinder pushes the lower mold to move upwards to be flush with the lower end surface of the lower mold, the feeding mechanism is driven by the third driving device to feed magnetic powder into the lower mold so as to reduce the labor intensity, the control is performed through an external controller, and powder filling is quantified to improve accurate control over the powder filling amount, and the stirring device stirs the powder to avoid bonding and scrape off the powder attached to the inner wall of the storage hopper.

Description

technical field [0001] The invention relates to the field of strong magnetic production, in particular to a strong magnetic powder molding device and method. Background technique [0002] At present, two types of sintered earth alloy magnets, samarium-cobalt-based magnets and rare-earth-iron-boron-based magnets, are widely used in various fields. Among them, the rare-earth-iron-boron-based magnet (hereinafter referred to as "R-T-(M)-B-based magnet", R is a rare-earth element containing Y, and T is iron or a transition metal substituted for iron and a part of iron element, M is an additive element, and B is boron) is a magnet with the highest magnetic energy product among various magnets, and its price is relatively cheap, so it is actively used in various electronic devices. As the transition metal contained in T, for example, cobalt can be used. In addition, boron may be partially replaced by C (carbon). [0003] In order to produce the rare earth magnet, a compact (pres...
