Abstract

The invention discloses a method for preventing the closure deformation of a magnetic core during the sintering process, comprising the following steps: S1: Pressing and forming the raw material of the magnetic core with the first arc-shaped hoop frame and the second arc-shaped hoop frame respectively, so that the magnetic core The raw materials are respectively combined with the first arc-shaped hoop frame and the second arc-shaped hoop frame to form the first semicircular magnet blank and the second semicircular magnet blank; S3: then the first semicircular mold and the second semicircular mold Insert the two ends of the two ends into the sliding joint seats on both sides of the top of the horizontal plate respectively; S4: the first L-shaped connecting plate and the second L-shaped connecting plate provided in the middle of the inner side of the first semicircular mold and the second semicircular mold They are respectively approached and fixedly connected by screws, so that the two ends of the first semicircular mold and the second semicircular mold are tightly inserted into the sliding joint seat; the present invention is simple and convenient to operate, preventing the first semicircular magnet blank and The second semicircular magnet blank is deformed during the sintering process, which is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of magnetic cores, and in particular relates to a method for preventing the deformation of the mouth of the magnetic core during the sintering process. Background technique [0002] The soft ferrite core blank is usually pressed and formed by a fully automatic powder forming press. At present, during the sintering process of the magnetic core blank in the kiln, the positioning of the blank is not firm, and its surface is not fastened, which leads to the easy deformation of the sintered magnetic core. Therefore, we propose a method to prevent the sintering of the magnetic core A method for closing and deforming during the process to solve the problems mentioned in the above-mentioned background technology. Contents of the invention [0003] The purpose of the present invention is to provide a method for preventing the deformation of the mouthpiece during the sintering process of the magnetic core, so as to...
