Embodiment approach

[0039] In order to better demonstrate the implementation process of the NdFeB magnetic powder molding die-casting device, this embodiment now proposes an implementation method of the NdFeB magnetic powder molding die-casting device, including the following steps:

[0040] Step 1: Pour the NdFeB magnetic powder raw material to be processed into the molding cavity 123 through the feeding funnel 1231, and open the hydraulic cylinder 22, and drive the cylinder ejector rod 212 to move through the hydraulic cylinder 22, and at the same time drive the pressure column 211 to approach the through hole 12231;

[0041] Step 2: continue to drive the pressing column 211 to move forward at high speed, and align the pressing block 2111 with the through hole 12231 and further extend into the inner cavity of the working cavity 1223 and the molding cavity 123 to carry out high-speed stamping of the NdFeB magnetic powder raw material;

[0042] Step 3: After the die-casting is completed, shrink t...

Abstract

The invention discloses a neodymium-iron-boron magnetic powder forming die-casting device and further discloses an implementation method of the neodymium-iron-boron magnetic powder forming die-castingdevice; the neodymium-iron-boron magnetic powder forming die-casting device comprises a powder filling forming mechanism and a rotary die-casting mechanism, and the rotary die-casting mechanism is installed on one side of the powder filling forming mechanism; an air cylinder is used for driving a push rod to move forwards and ejecting a formed neodymium-iron-boron magnet out of a through hole, then a pressing block is fixedly arranged at the top end of a pressing column and matched with the through hole, a magnet suction ring is further connected to the outer wall of the pressing column in aglued mode. When the rotary motor is started, the driving wheel and the transmission belt are used for driving the driven wheel to rotate, so that the rotating shaft is in linkage with the rotating rod structure to rotate at a low speed, and the formed neodymium-iron-boron magnet is attracted out of the through hole through the magnet attraction ring. Compared with the mode that the neodymium-iron-boron magnet is ejected out through a push rod, the device can also utilize the magnet attraction principle to attract the neodymium-iron-boron magnet out of the through hole through the magnet attraction ring, and the neodymium-iron-boron magnet can be taken out and collected more conveniently.

Description

technical field [0001] The invention relates to the technical field of NdFeB magnetic processing equipment, in particular to an NdFeB magnetic powder forming die-casting device and an implementation method thereof. Background technique [0002] NdFeB permanent magnet materials are the most concerned rare earth application industry in my country's rare earth industry. With the development of science and technology and technological progress, the demand for high-performance NdFeB permanent magnet materials is becoming more and more extensive. As we all know, in order to improve the coercive force of magnets, methods such as adding a small amount of heavy rare earth elements (such as Dy, Tb, etc.) or refining magnet grains and controlling grain morphology are usually used. In order to achieve the purpose of refining the magnet grains, it is usually used to add a small amount of W, Mo, V, Ti, Ta, Zr, Nb, Co, Cr, Ga and other elements into the magnet composition to inhibit the gr...
