Abstract (en)
A machine for punching sheet metal comprises means (3, 4, 5, 7) for feeding a sheet metal strip (1) to means (8, 9) for punching the strip (1) of sheet metal. Said means for punching the strip (1) comprise a plurality of punching presses each comprising a plurality of elementary individual punching tools (20, 21) that can be operated individually. Each of said punching presses has a supporting structure (16) shaped like a swan's neck with an intermediate channel (100) through which there passes the sheet metal strip (1); the punching presses (8, 9) are arranged in sequence along the longitudinal direction of the strip (1) so as to extend in part on one side and in part on the other side of the strip (1), and they are independently mobile along a transversal direction of the strip (1), so as to allow the complete extraction of the strip (1) from the respective channels (100) and the complete extraction of each swan's neck structure from the space extending between two adjacent swan's necks, and along the longitudinal direction of the strip (1) so as to allow the interchangeability of the individual punching presses (8, 9) within said sequence, so as to be able to position the respective elementary punching tools (20, 21) according to an arrangement pre-established in the plan of operations. <IMAGE>
