Abstract

The invention provides a method for producing a ferrite core. The method comprises the following steps: a proportioning: weighing 52 to 54 parts by weight of iron oxide, 32 to 36 parts by weight of manganous-manganic oxide, 9 to 10 parts by weight of zinc oxide, 6 to 9 parts by weight of nickel oxide, 3 to 4 parts by weight of manganese dioxide, 2 to 6 parts by weight of lithium oxide, 10 to 14 parts by weight of carbon fiber, 2 to 4 parts by weight of coupling agent, 1 to 3 parts by weight of flexibilizer and 1 to 3 parts by weight ofanti-shrinking agent to acquire a mixture; b molding: carrying out compression molding treatment on the mixture through a press to obtain a blank; c sintering: sintering the blank through a sintering furnace to obtain a sintered part; d typesetting: typesetting the sintered part; e grinding: grinding the sintered part through an automatic grinding, cleaning and drying all-in-one machine to obtain a finished product ; f sorting: carrying out size sorting treatment on the finished product through an automatic sorting machine; g inspecting the finished product: inspecting the appearance and the electromagnetic performance of the sorted finished product;h packaging: packaging the qualified finished product; and i warehousing: warehousing and storing the packaged finished product.

Description

technical field [0001] The invention belongs to the technical field of magnetic cores, and relates to a production method and a device for a ferrite magnetic core. Background technique [0002] Ferrite core is a high-frequency magnetic material (the principle is the same as silicon steel sheet, but it is used in high-frequency environment), mainly for high-frequency transformers (such as switching power supplies, line output transformers, etc.), high-frequency magnetic rings ( Anti-interference), etc., increase the magnetic permeability, improve the quality factor of the inductance, and use it in the transformer. [0003] There is no complete production method in the prior art, so it is necessary to design a production method and device for a ferrite core. Contents of the invention [0004] The first purpose of the present invention is to propose a production method of a ferrite core, which is characterized by convenient production, in view of the above-mentioned problems...
