Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core powder processing, in particular to a powder forming device for an anti-interference type chip inductor magnetic core. Background Art

[0002] Magnetic core: Magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has the characteristics of low loss. Nickel-zinc ferrite has extremely high resistivity and low magnetic permeability of less than a few hundred. Ferrite cores are used in coils and transformers of various electronic devices.

[0003] When producing inductor cores, the raw material particles need to be ground. The existing grinding machine has a relatively simple structure, which is not convenient for fine division of labor between coarse grinding and fine grinding, which easily causes the quality of the finished powder to be substandard and affects subsequent processing; and the existing grinding equipment adopts an intermittent feeding design, and multiple processing requires batch feeding, which is less practical.

[0012] Preferably, arc-shaped baffles are fixed on both sides of the lower end surface of the cover plate, and the baffles are located outside the upper end of the turntable, and the baffles correspond to the discharge openings. The baffles cover the discharge openings on both sides to prevent the granular materials from directly entering the fine grinding area.

The fine grinding block pushes the granular material to move toward the turntable to complete the fine grinding operation, and the composite standard powder passes through the screen and falls into the storage box for storage.
