Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ferrite core processing, in particular to a ferrite core chamfering device. Background Art
[0002] Ferrite cores are mostly formed by dry pressing with a mold. During the dry pressing process, burrs and mold steps are prone to appear at the corners of the core. If the burrs or mold steps of the core are not processed, the coil is likely to be damaged during the subsequent coil winding process, reducing the yield of the product, and may also cut the staff, causing safety hazards.
[0003] The existing ferrite core chamfering device can only chamfer one side of the ferrite core. After the chamfering of one side is completed, the other side needs to be chamfered again, which greatly affects the chamfering operation of the device on the ferrite core. At the same time, the device is not convenient for fixing ferrite cores of different sizes, which makes the ferrite core easy to shake during the chamfering operation, thereby reducing the chamfering efficiency of the device.
