Description

[technical field] [0001] The invention relates to a rare earth permanent magnet material processing equipment, in particular to a rare earth permanent magnet material near net shape processing equipment. [Background technique] [0002] Rare earth permanent magnet material is an important basic functional material. Its main function is to provide stable magnetic flux without consuming energy. It is one of the important means of saving energy. widely used. Rare earth permanent magnet materials are manufactured by powder metallurgy process. High-intensity magnetic field orientation is required when magnetic material powder particles are compacted. Due to the parallel magnetic flux of the two poles of the orientation magnetic field and the anisotropy of magnetic powder materials, during the process of orientation compaction, the magnetic powder particles The magnetic powder will be rearranged along the magnetic force line, and the pressed shape and pressed size that are compati...

Problems solved by technology

In the traditional process, it can only be oriented and pressed to make a larger square or cylindrical shape, and then it is sintered and then subjected to secondary cutting processing. Due to the high hardness and brittle texture of the powder sintered block, it is difficult to process and the processing efficiency is very low. In addition, Due to the high inherent value of rare earth products, the loss of cutting tools and leftover materials during processing also accounts for a large proportion of the cost, so the production cost has always been high. In order to solve the above-mentioned problems of processing efficiency and processing cost, different styles of The mold is subjected to orientation pressing processing in order to obtain a raw material close to the shape and size of the finished product. Due to the change of the mold shape and pressing size, the distribution of the orientation magnetic field will be affected, which will affect the orientation of the magnetic powder particles and seriously affect the final performance of the sintered product. Only low-grade magnetic raw materials can be produced, and it is very difficult to produce high-grade magnetic raw materials in this way
