Device for producing metal sheets or hollow chamber plates from extruded profiles

An apparatus for producing flat metal sheets (19) or hollow chamber plates (20), comprising:

• an extruder (1) for producing an extruded profile (7) with a longitudinal opening;
• a separating device (6) for cutting the extruded profile (7) to length corresponding to a length of the flat metal sheets (19) or the hollow chamber plates (20) to be produced;
• a bending unit (4) for widening the longitudinal opening and creating a-U-shaped configurations of the extruded profile (7);
• a first expansion unit (3) for expanding a first of the U-shaped configurations into the flat metal sheets (19) or the hollow chamber plates (20);
• a first stacking unit (5) arranged downstream of the first expansion unit (3);
• a second expansion unit (3) for expanding a second of the U-shaped configurations of the extruded profile (7) into the flat metal sheets (19) or the hollow chamber plates (20);
• a second stacking unit (5) arranged downstream of the second expansion unit (3);
• and
• a robot for transferring the first of the U-shaped configurations from the bending unit (4) to the first expansion unit (3) and for transferring the second of the U-shaped configurations from the bending unit (4) to the second expansion unit (3),
• wherein the extruded profile (7) emerges from the extruder (1) in a direction of extrusion,
• wherein the first expansion unit (3) and the second expansion unit (3) are arranged parallel to the direction of extrusion on opposite sides of the bending unit (4) such that an axis perpendicular to the direction of extrusion extends through at least a portion of the bending unit (4), the first expansion unit (3) and the second expansion unit (3).
