Description

Technical Field

[0001] The utility model relates to the technical field of magnetic ring production, in particular to a magnetic ring hole-making device. Background Art

[0002] It is a commonly used anti-interference component in electronic circuits, effectively suppressing high-frequency noise. It is generally made of ferrite. Magnetic rings have different impedance characteristics at different frequencies. Generally, the impedance is very small at low frequencies, but the impedance of the magnetic ring increases sharply as the signal frequency increases.

[0003] The existing Chinese utility model patent with reference publication number CN206543894U discloses a magnet punching machine with good concentricity, comprising a machine base, a power switch, a first slide rail, a second slide rail, a first slide plate, a second slide plate, a blade, a punching knife, a positioning knife, a small disk operating rod, a large advance and retreat disk base, an advance and retreat disk, an advance and retreat disk operating rod, an advance and retreat push rod, a workpiece chuck, a workpiece, a concentric spindle, a clutch lever, a tension clamp, a motor, a belt pulley, and a belt. The workpiece is mounted on the workpiece chuck and fixed. The positioning knife first positions the magnet. The punching knife is laterally punched by the first slide rail, the first slide plate, the large advance and retreat disk base, the advance and retreat disk, the advance and retreat disk operating rod, and the advance and retreat push rod. The punching knife is further longitudinally moved by the second slide rail, the second slide plate, and the small disk operating rod to punch holes, thereby being suitable for punching magnets with different aperture requirements. Furthermore, a water pipe is provided to spray water on the magnet to prevent sparks from flying during punching, thereby providing a high safety index.

[0004] The debris generated by the existing magnetic ring drilling equipment during use will adhere to the surface of the magnetic ring and the cutter head. After the drilling is completed, the surface of the magnetic ring needs to be cleaned, which is very inconvenient. At the same time, the existing drilling equipment generally fixes the magnetic ring with a clamp, which is cumbersome and inconvenient to operate. Utility Model Content
