Vorrichtung zum Lochen von blattförmigen Materialien

摘要

A sheet machining apparatus (10) has a die (20) for placing a sheet (16) to be machined thereon, the die (20) being mounted on a lower die base (12) for movement in the direction indicated by the arrow B and having a machining pattern (18) for the sheet (16), a plurality of punches (22) mounted on an upper punch base (14) for machining the sheet (16) in coaction with the die (20) in a predetermined number of machining cycles according to the machining pattern (18), and a feed mechanism (24) for horizontally moving the die (20) to align a machining position on the sheet (16) with the punches (20) each time the sheet is machined by the die (20) and the punches (22). The sheet machining apparatus (10) is relatively simple in structure and can machine various sheets with high accuracy.
