Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core production, and particularly relates to a blanking machine for magnetic cores. Background Art

[0002] A magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures, which is widely used in fields such as motors, generators, sensors, and mechanical equipment due to its excellent magnetic properties. To exert its best performance, it is necessary to sinter the green blank into a mature blank through a sintering process to enhance the mechanical strength and wear resistance of the material, and at the same time improve its magnetic properties. During the sintering process, by controlling the sintering atmosphere, oxides on the surface and inside of the material can be effectively removed, and the oxygen content can be reduced, which helps to improve the antioxidant performance and stability of the magnet. However, during the sintering process of the magnetic core, the grains of the green blank will grow with the change of temperature. If the blank discharging distance is too close, the formed mature blanks are likely to adhere to each other. Summary of the Utility Model
