Full-automatic pressure-free magnetic powder forming machine and manufacturing method of magnetic powder forming blank

Abstract

The invention relates to a device and a method of a full-automatic pressure-free magnetic powder blank manufacturing machine. An full-automatic pressure-free magnetic powder forming machine comprises a one-mold multiple-output magnetic powder forming blank which is used for sintering anisotropic magnetic powder into magnet and a manufacturing system device, which does not need to bring the mold into a furnace for sintering, of a magnet sintering body, the manufacturing system device comprises a side wall mold, a powder distribution device which is used for a powder distribution procedure supplying magnetic powder to a powder distribution material box, a pneumatic beating device which is used for filling the side wall mold with the magnetic powder in the powder distribution material box, and a powder throwing forming device used for enabling the closed side wall mold filled with the magnetic powder to freely fall to form a magnetic powder blank forming body, an orientation mechanism which is used for taking the closed side wall mold filled with the magnetic powder blank forming body as magnetic field and a rotary disassembling device which is used for disassembling the side wall mold in rotary mode to take out the magnetic powder forming blank, and the side wall mold comprises a side plate, an end plate, a bottom plate, a partition plate, a magnetic pole and a cover plate and is divided into two or more spaces. According to the full-automatic pressure-free magnetic powder forming machine, the problem that in the prior art, the mold and the magnetic powder in the mold are sintered together is solved.

Description

technical field [0001] The invention relates to the technical field of magnetically anisotropic rare earth sintered magnets, in particular to a fully automatic non-pressure magnetic powder molding machine and a method for manufacturing magnetic powder molding blanks. Background technique [0002] In the existing thin-plate-shaped rare earth sintered magnet method, the sintered magnet needs to connect the mold with the magnetic powder in the mold and sinter the mold together, which has the following disadvantages: (1) a large number of molds are required, because the mold must be precision-made, so the mold production cost is high . (2) In order to use the mold to repeatedly enter the sintering furnace for sintering, it is necessary to increase the wall thickness of the mold, the partition and other parts, and the material cost increases; (3) At the same time, the occupied volume of the mold increases, so that the powder filling device, powder magnetic field orientation devic...
