阅读说明：本技术 一种ef92.5磁条坯件的排坯方法 (Blank arranging method for EF92.5 magnetic strip blank ) 是由 郑娇 于 2019-08-12 设计创作，主要内容包括：本发明公开了一种EF92.5磁条坯件的排坯方法,将EF92.5磁条坯件竖放并行紧密排列,在排好的坯件上撒上氧化锆粉,横放若干列坯件,横放的若干列坯件之间留有空隙,然后在横放的若干列坯件上面再竖放若干列坯件,竖放的若干列坯件之间留有空隙。该方法使坯件在烧结过程中收缩一致,烧结后的产品尺寸一致性好,无裂纹和断裂,对烧结后的弯曲和变形有明显改善。(The invention discloses a blank arranging method of EF92.5 magnetic strip blanks, which comprises the steps of vertically arranging the EF92.5 magnetic strip blanks in parallel and tightly arranging, scattering zirconium oxide powder on the arranged blanks, horizontally arranging a plurality of rows of blanks, leaving gaps among the horizontally arranged blanks, then vertically arranging a plurality of rows of blanks on the horizontally arranged blanks, and leaving gaps among the vertically arranged blanks. The method ensures that the blanks shrink consistently in the sintering process, the sintered products have good size consistency and no cracks or fractures, and the bending and deformation after sintering are obviously improved.)

1. A blank arranging method for EF92.5 magnetic strip blanks is characterized in that zirconium oxide powder is scattered on the arranged blanks, a plurality of rows of blanks are horizontally arranged, gaps are reserved among the horizontally arranged blanks, then a plurality of rows of blanks are vertically arranged on the horizontally arranged blanks, and gaps are reserved among the vertically arranged blanks.

2. A bank method of EF92.5 magnetic stripe blanks according to claim 1, wherein the blanks laid horizontally are in two rows, the blanks laid vertically on the top are in four rows, and the blanks laid horizontally and the blanks laid vertically form a 'well' shape.

Technical Field

The invention relates to the technical field of manganese-zinc ferrite magnetic core production, in particular to a blank arrangement method of an EF92.5 magnetic stripe blank.

Background

The EF92.5 magnetic strip is a ferrite applied to various electromagnetic cookers and the like, is green, energy-saving, low-carbon and environment-friendly, and has large international and domestic market demand.

The EF92.5 magnetic strip has high difficulty in the production process of products, mainly has high requirements on flatness and shape and position, has strict requirements on deformation and bending of finished products, and is an important factor influencing the quality of the products.

In the existing mass production process of the EF92.5 magnetic stripe, the blanks are vertically arranged side by side and sintered in a single-firing mode, and because the blanks are too long, the blanks are provided with four small pins, the blanks are easy to bend and deform, the qualification rate of the products is reduced, and the quality of the products is influenced.

Disclosure of Invention

The invention aims to solve the problems and provides a blank arranging method of an EF92.5 magnetic stripe blank, so that the shrinkage of the blank is consistent in the sintering process, and the bending and deformation of a sintered product are reduced.

The purpose of the invention is realized by the following technical scheme:

a method for arranging EF92.5 magnetic stripe blanks comprises the steps of vertically arranging the EF92.5 magnetic stripe blanks in parallel and closely arranged, scattering zirconium oxide powder on the arranged blanks, horizontally arranging a plurality of rows of blanks, leaving gaps among the horizontally arranged blanks, vertically arranging a plurality of rows of blanks on the horizontally arranged blanks, and leaving gaps among the vertically arranged blanks.

Preferably, the horizontal blanks are in two rows, the uppermost vertical blank is in four rows, and the horizontal blanks and the vertical blanks form a 'well' shape.

The invention has the following beneficial effects:

the blank arranging method of the EF92.5 magnetic stripe blank provided by the invention ensures that the blanks shrink consistently in the sintering process, the size consistency of the sintered product is good, no crack or fracture exists, and the bending and deformation after sintering are obviously improved.
