  • the part to be bent can be gripped on one of its flat sides by forces acting on one side of the flat side in a pulling manner at several longitudinally consecutive points, after which the holding unit can in turn be pivoted relative to a pivotable carrier unit about a first pivot axis parallel to the longitudinal direction, with the pivotable carrier unit pivotable relative to a pivotable support base about a second pivot axis parallel to the first pivot axis, and wherein the pivotable support base is movable in a direction transverse to the second pivot axis by a support base moving unit.
  • WO 97/32677 A1 shows a device for bending a metal sheet, comprising a frame, a stationary lower beam with a lower clamp, a movable upper beam with an upper clamp, the clamps each having a clamping surface for clamping a metal sheet in a working position, a lower bending beam and a Upper bending beam for bending a clamped metal sheet upwards or downwards, the bending beams being mounted on both sides in a carrier plate so that they can rotate about a corresponding axis, the carrier plates being movably mounted in the frame in such a way that the lower or upper bending beam is in can be moved to a working position in which its axis lies essentially in the plane of the clamping surface of the lower or upper clamp.

  • the flexures are attached to the jaws by spatial mechanisms, preferably ball joint couplings, and positioned longitudinally by mechanically or hydraulically actuated displacement devices.
  • the suction cups of the placement unit are directly connected to the movement control, for example a parallelogram mechanism, of the processing tools, so that only a corresponding drive has to be provided via the sections of the processing machine.
  • the suction cups can be mounted in a row on a frame. It is also possible to provide two rows of suction cups.
  • the plane of the suction cups forms an acute angle with the horizontal plane of the feed table, in particular an angle between 70 and 85 degrees.

  • the placement unit is positioned transversely to the processing tool or tools laterally within the associated cheek for a feed movement of the flat component in In the direction of the processing edge of the flat component, a loading movement can be accomplished via a rail that is pivotably connected to the upper part, thereby enabling the flat component to be lifted off a loading table.

  • the placement unit can be moved transversely to the processing tool or tools, that is to say parallel to the processing edges of the processing tool or tools, and is connected to this cheek within the associated cheek. This enables the feed movement of a flat component in the direction of the processing edge of the flat component, which enables the device to be loaded forwards in front of the machine directly after a processed flat component has been ejected.
  • the loading or transfer table is arranged in a parallel plane and higher than the plane defined by the feed table, so that the transfer of the flat component is possible without an additional pivoting movement of the placement unit.
  • a free space is provided between the transfer table and the feed table as a parking space for the placement unit, so that the processing machine can carry out the clamping movement of the cheeks required for the folding movement of a flat component without this placement unit spatially impeding such a movement.
  • both placement units are used in combination, so that one person feeds flat components to the machine and these alone after the processing is complete turned over or cannot be removed from the machine.
  • the two placement units have in common that they feed the flat component from the outside into the interior without having to open the clamping jaws very far, which takes a certain amount of time with the processing machines.
