ABSTRACT:
A hybrid press installation employs a plurality of individual presses including a drawing press and transfer presses. These presses, by means of frames, are set up on common installation surfaces. A tool is assigned to each press which includes a head piece, a slide and a press bed and a sliding table. The tools can be exchanged by means of the sliding tables. A transfer device extends through the hydrid press installation, the components of this transfer device being arranged above the sheet metal conveying plane, and gripping the sheet metal parts from above. Intermediate depositing devices are positioned between two working stages. As a result, a reduction of the length of the transfer movement of the sheet metal parts per slide stroke is achieved. In this manner, large-surface and/or thin-walled and therefore unstable sheet metal parts can be transferred.
