Abstract: A combined machine for punching and laser cutting of a flat sheet metal includes a fixed base, a fixed punching head, a laser cutting head and a manipulator for the movement of the sheet metal on a Cartesian plane. The laser cutting head is carried by a variable-aperture compass structure, which is mobile along a linear guide.

Abstract: A manipulator at low inertia for laser cutting machines of flat sheet metals is described, which comprises a longitudinal movement axis X and a transversal movement axis Y perpendicular to said longitudinal axis and parallel to the plane of the sheet metal, and a supporting equipment (15) for a laser cutting head (14) which is displaceable along said axes. The supporting equipment (15) comprises two sliding blocks (5, 6) driven by respective independent actuators (7, 8) to move along the axis Y at a variable mutual distance, and rods (9, 10) for the articulated connection of said sliding blocks (5, 6) to said laser cutting head (14).

Abstract: A combined machine is described, for punching and laser cutting of a flat sheet metal. The machine comprises a fixed base (1), a fixed punching head (7), a laser cutting head (10) and a manipulator (4) for the movement of the sheet metal (6) on a Cartesian plane (XY). The laser cutting head (10) is carried by a variable-aperture compass structure (9), which is mobile along a linear guide (8).

Abstract: A press brake for metal sheets is described, comprising a tool for bending the metal sheet; the tool comprising a die and pressure means opposite to said die and adapted to press the metal sheet against the die to determine the bending of the metal sheet. The pressure means comprise a plurality of first segments aligned along the bending direction of the metal sheet and adapted to press said metal sheet against the die. The press brake comprises control means adapted to change the longitudinal dimension of the pressure means; the control means are adapted to individually drive each first segment for its longitudinal sliding along the bending direction of the metal sheet, so that the longitudinal dimension of the pressure means corresponds to the longitudinal dimension of the fold to be carried out on the metal sheet.

Abstract: A manipulator of a metal sheet (4) is disclosed, comprising pickup means (8) for picking up the metal sheet, which pickup means (8) is connected to a rack (3) associable with a first pinion (1) and an operating head (9). The manipulator comprises at least a second pinion (2) and the first (1) and the second (2) pinions are arranged along the movement path of the metal sheet (4); at least one between the first (1) and the second (2) pinions are each time engaged with said rack (3) to move the rack from one part to the other of the operating head (9) (FIG. 2).
