Abstract

The invention belongs to the field of rare earth permanent magnet production and relates to a reciprocating type blank pressing device for rare earth permanent magnet production. The device comprises a first support frame, a pushing assembly, a pressing assembly, a vibration assembly and the like; the pushing assembly is arranged on the first support frame; the pressing assembly is arranged on the pushing assembly; and the vibration assembly is arranged on a second support frame. Through cooperation of an extrusion frame and devices on the extrusion frame, the extrusion frame can extrude a rare earth raw material in a limiting frame and enable the rare earth raw material to be molded; and due to the fact that the limiting frame is rectangular, a pressed rare earth permanent magnet blank is square, and the effect that the rare earth raw material can be automatically pressed into the square rare earth permanent magnet blank is achieved.

Description

technical field [0001] The invention relates to the field of rare earth permanent magnet production, in particular to a reciprocating blank pressing device for rare earth permanent magnet production. Background technique [0002] Permanent magnet motors have a series of advantages such as energy saving, environmental protection, and stable operation. The materials of permanent magnet motors are rare earth permanent magnet materials. Permanent magnets processed from rare earth materials have become the first choice for permanent magnet motor materials due to their stable and superior performance. Rare earth permanent magnets The material is an alloy composed of samarium, neodymium mixed rare earth metals and transition metals, which is pressed and sintered by powder metallurgy and magnetized by a magnetic field. The permanent magnet technology is widely used, which depends on the material and technology. improvement. [0003] Rare earth permanent magnets are made of rare ear...
