Description

Technical Field

[0001] The invention relates to the technical field of manganese-zinc ferrite core production, in particular to a powder adding device for a vertical press. Background Art

[0002] With the rapid replacement of electronic products at home and abroad, the standards and requirements for electronic devices and electronic transformers are getting higher and higher. The design of power transformers is developing towards high efficiency, light weight and miniaturization. Manganese-zinc ferrite core is a core used for high-definition flat-screen TVs and power transformers.

[0003] In the manufacturing process, ferrite core is one of the core materials for producing transformers. In integrated boards, devices with small leakage flux, small leakage inductance, low noise and low heat generation have always been the preferred direction. Existing magnetic cores often use a cylindrical structure with a central column, which has the characteristics of low loss.

[0004] In the production process of manganese-zinc soft magnetic ferrite, it is necessary to first form and press the green sheet, specifically by installing a mold on a vertical press, filling the mold with powder, and forming the powder into a green sheet with a certain strength.

[0005] In the original powder adding device, powders of different particle sizes are clearly layered in four directions, with fine particles in the middle of the barrel, coarse particles at the edge of the barrel, fine particles in the lower part, and coarse particles in the upper part. A stainless steel pipe with an inner diameter of 70mm is used for connection. The layered particles flow directly into the feeding box through the stainless steel pipe, resulting in a vertical press with a two-piece mold. The formed blanks have large differences in inspection parameters such as weight, size, and density, resulting in defective blanks. This method is not only time-consuming and labor-intensive, but also wastes manpower and has an important impact on product quality. For this reason, a powder adding device for a vertical press is designed. Summary of the invention
