ABSTRACT:
This device is especially suited for gripping heavy and cumbersome pieces of sheet metal without human force and transporting them from a stacking device to a bending press for further processing. By means of rotatable clamping of gripping jaws mounted on a vertically movable jaw carriage, a laterally movable first horizontal carriage, a longitudinally movable second horizontal carriage and a swivel or turning device, any piece of sheet metal can be directly rotated or turned about a horizontal gripping jaw axis or can be rotated in the plane of the sheet and then regripped, or can be subjected to both actions. The piece of sheet metal normally held by two pairs of jaws is further supported below the jaw axis by multi-component sheet metal support devices carried on two independently movable sheet metal support carriages. This makes it possible to position each edge of the metal sheet or panel in the operating region of a suitable tool, such as a bending die for upward and downward bending operations and to hold the sheet metal sheet in position during the working operation.
