Description

technical field [0001] The invention relates to a permanent magnet forming and magnetizing device, in particular to a magnet forming magnetic field monitoring and magnetizing device which can directly measure and monitor the forming magnetic field. Background technique [0002] From the perspective of the development history of permanent magnet materials, the carbon steel used at the end of the 19th century had a magnetic energy product (BH)max (a physical quantity that measures the magnetic energy density of a permanent magnet) less than 1MGOe (mega-high), while the mass-produced Nd-Fe abroad -B permanent magnet material, the magnetic energy product has reached more than 50MGOe. Over the past century, the remanence Br of the material has increased very little, and the increase in energy product is due to the increase in coercive force Hc. The improvement of coercivity is mainly due to the understanding of its nature and the discovery of high magnetocrystalline anisotropy c...

Problems solved by technology

These are the main permanent magnet materials on the market, and some are eliminated due to the original production process or cost, which cannot be widely used, such as Cu-Ni-Fe (copper-nickel-iron), Fe-Co-Mo (iron-cobalt-molybdenum) , Fe-Co-V (iron cobalt vanadium), MnBi (manganese bismuth)

[0009] Artificial permanent magnets need to be magnetized during their molding process, so that the magnets are magnetic, and the size of the magnetized magnetic field will directly affect the quality of magnetization. In the prior art, considering the shielding effect of the equipment and the magnetic flux leakage factors, It is impossible to monitor the magnetizing magnetic field effectively and intuitively, which affects the magnetizing efficiency
