Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant sheet production, in particular to a deburring device for permanent magnet production. Background Art

[0002] Permanent magnets are materials that can continuously generate magnetic fields. They are widely used in industries such as motors and aviation. Common ones include ferrite oxide, barium ferrite, and neodymium iron boron. According to the specific type of permanent magnet material, the corresponding raw materials are prepared, such as iron oxide, barium carbonate, neodymium, iron, etc. Permanent magnet materials are usually prepared using powder metallurgy. After the raw material powders are mixed, they are pressed into shape and then sintered at high temperatures. During the sintering process, the powder particles combine into blocks to form a material with a certain degree of magnetism. The sintered material needs to be magnetized to obtain a lasting magnetism. This is usually done by treating it in a strong magnetic field so that the microstructure of the material is oriented and arranged, thereby forming permanent magnetism.

[0003] Since burrs will appear at the corners of the blank after the pressing and sintering processes, the traditional grinding method requires manual identification of the burr position, and then the side to be polished is turned towards the grinding wheel for grinding. This grinding method has low molding efficiency and certain risks. Therefore, we propose a new deburring device for permanent magnet production. Utility Model Content
