Sintering device and sintering method for MnZn ferrite high-permeability ring blank

Abstract

The invention is applicable to the technical field of ferrite magnetic rings, and provides a sintering device and a sintering method of a MnZn ferrite high-permeability ring blank. The sintering device comprises a sintering assembly and a transmission assembly. The sintering assembly comprises a sintering kiln, a supporting part, a storage box and a telescopic hos; the sintering kiln is fixedly connected to the top of the supporting part; the storage box is fixed to the outer wall of the supporting part; the telescopic hose is fixed to the bottom of the storage box and communicates with the interior of the storage box; and zirconium oxide powder is contained in the storage box. A zirconium pressing plate can be driven to the lowest position through a hydraulic cylinder, then the telescopichose is aligned to the zirconium pressing plate, zirconium oxide powder in the storage box can be guided into the zirconium pressing plate through the telescopic hose, a cushion layer is formed on the zirconium pressing plate in a laid mode, the magnetic ring is placed on the cushion layer, the cushion layer is used for replacing an original cushion body, and the increase of the sintering cost ofthe magnetic ring caused by the disposable use of the pad body is avoided to further reduce the unnecessary economic cost loss.

Description

technical field [0001] The invention belongs to the technical field of ferrite magnetic rings, and in particular relates to a sintering device and a sintering method for a MnZn ferrite high magnetic permeability ring blank. Background technique [0002] Ferrite magnetic rings mainly include nickel-zinc ferrite magnetic rings and manganese-zinc ferrite magnetic rings. These two types of magnetic rings have strict distinctions for different frequencies. The nickel-zinc ferrite magnetic ring is suitable for suppressing electromagnetic interference in the high-frequency band; the manganese-zinc ferrite magnetic ring is suitable for suppressing electromagnetic interference in the low-frequency band. smaller. According to different requirements, different processes can be selected to manufacture magnetic rings. The magnetic ring has different impedance characteristics at different frequencies. Generally, the impedance is very small at low frequencies. When the signal frequency i...

Problems solved by technology

[0004] The invention provides a sintering device and a sintering method for a MnZn ferrite high magnetic permeability ring blank, aiming at solving the problem of using a magnetic ring with a slightly thinner compact thickness of a special high-conductivity powder material as the bottom of the stack firing in the conventional method currently used in the industry. Gasket, and the gasket will be scrapped after a single use, thus indirectly causing the problem of increasing the cost of magnetic ring sintering
