Abstract

The invention discloses a preparation technology of an anti-interference soft magnetic ferrite magnetic core, and belongs to the field of soft magnetic ferrite magnetic core preparation. According to the scheme, a grinding driving mechanism drives a rotating disc and a grinding roller to fully grind the edge of the soft magnetic ferrite magnetic core, the grinding effect is enhanced, and the anti-interference soft magnetic ferrite magnetic core is obtained. The scrap blowing and guiding mechanism drives an extrusion plate to reciprocate by means of the attraction force between a magnet ring and a magnet block and the interaction of the elastic effect of a telescopic spring and rotating centrifugal force, cold air of the stainless steel ice blocks is intermittently extruded to be sprayed out, scraps on the inner side are blown to move towards the outer side, collection of the scraps is facilitated, and the cooling effect is achieved by means of the cold air; and the rotating disc rotates to blow chippings and cold air to fall into the collecting frame, the chippings carry heat, a temperature change attraction mechanism enables a deformation memory spring to deform to extend or contract by means of cold and hot changes, movable hanging barrels are pushed to collide and rub with one another, static electricity is generated, adsorption to the chippings is enhanced, the chippings are collected and cleaned more sufficiently, and the chipping cleaning effect is enhanced.

Description

technical field [0001] The invention relates to the field of preparation of soft ferrite cores, in particular to a preparation process of an anti-interference soft ferrite core. Background technique [0002] The ferrite core is made of non-metallic magnetic material with dense and homogeneous ceramic structure. It has low coercivity, also known as soft ferrite. Compared with other types of magnetic materials, the advantage of ferrite is that it The conductivity is very high, and it has the advantages of high resistance and low eddy current loss in a wide frequency range. [0003] At present, ferrite cores are susceptible to interference during use, which leads to poor use. Therefore, it is necessary to prepare ferrite cores with excellent anti-interference performance, and during the preparation process, it is necessary to treat the sintered soft magnet Oxygen cores are polished, but the debris is easy to splash during the grinding process, and it is not easy to clean. Co...
