パンチ装置
Document Type and Number:
Japanese Patent JPH06320
Kind Code:
B2
Abstract:
A punch apparatus for punching hole patterns in thin sheet material. The apparatus includes a housing having a liquid-cooled cavity (46) therein; a coil (58) mounted in the liquid-cooled cavity; a driver disk (48) made of a highly conductive material mounted in the liquid-cooled cavity, the driver disk mounted adjacent to the coil; a driver button (49) located outside of the liquid-cooled cavity but in communication with the driver disk; and a punch element (32) for perforating thin sheet material aligned with the driver button. Finally, the apparatus includes an electrical source for energizing the coil with a pulse of electrical energy for generating flux linking the driver disk and the coil to repel the driver disk from the coil, thereby translating the driver button and the punch element, causing the punch element to perforate a thin sheet of material.
