Device for magnetic field radiation

Abstract

The invention discloses a device for magnetic field radiation, which comprises a lower crossbeam of a multi-pole orientation and radiation orientation multifunctional magnetic field press. A lower punch is fixed on the lower crossbeam; the structure of fixing the lower punch on the lower crossbeam is formed by enabling the lower crossbeam and the lower punch to be plugged by a plugging device; theplugging device comprises a plugging part and a plugging section; the bottom of the plugging part is bonded to the top wall of the lower crossbeam by a bonding agent; the plugging part comprises a plate-shaped main body and a pair of plugging plates; the top wall of the plate-shaped main body is provided with a connecting port; and the plate-shaped main body can be cuboid-shaped or cube-shaped. The defects that the mounting mode of combining the structure of fixing the lower punch on the lower crossbeam with other positioning pieces by using bolts in the prior art is not simple and tedious, the making process of the multi-pole orientation and radiation orientation multifunctional magnetic field press is not facilitated, the bolt is easily damaged by corrosion of the external environment and is hard to maintain can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of magnetic field radiation, in particular to a device for magnetic field radiation. Background technique [0002] Neodymium magnet (Neodymium magnet), also known as NdFeB magnet (NdFeB magnet), is a tetragonal crystal formed by neodymium, iron, and boron (Nd2Fe14B). In 1982, Masato Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product (BHmax) of this magnet is greater than that of the samarium cobalt magnet, and it was the material with the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metals successfully developed the powder metallurgy process, and General Motors successfully developed the melt-spinning process, which was able to prepare NdFeB magnets. This kind of magnet is the second most magnetic permanent magnet after the absolute zero holmium magnet, and it is also the most commonly used rare earth magnet. NdFeB magnets are ...
