The device includes a plurality of punches (b1-b6) and dies (B min ) of different shapes, and a moving assembly, for supporting a holder frame (2), which moves a workpiece along both X- and Y-axes on a working table (1). A control unit (4) is provided for inputting punching positions on the workpiece as well as the shape(s) of the holes (c) to be punched, as well as for controlling operation of the moving assembly and punching units (B1-B6) in response to inputted data, and for moving the punching positions of the workpiece below the desired punching units (B1-B6) to perform punching operations. The punching units (B1-B6) each comprises a substantially &sqsup& -shaped supporting member (6) in which a piston (7) is provided for moving a punch upwardly and downwardly. The punch (b1-b6) is provided in one arm of the &sqsup& - shaped support member (6), with a corresponding die (b min ) in a lower portion of the support member (6).</p> |
