ABSTRACT:
A transfer press for a stepwise deformation of workpieces includes a plurality of stages arranged in a series and an arrangement for intermittently advancing the workpieces from one stage to a successive stage. Some of the stages are work stages for deforming the workpieces by workpiece-deforming tools and at least one of the stages is an empty stage void of tools. There is further provided a workpiece-supporting arrangement situated in the empty stage for supporting a workpiece while the workpiece dwells in the empty stage and a tool-supporting table normally situated in a work stage in a working position adjacent the empty stage and being displaceable for effecting tool replacement thereon. The workpiece-supporting arrangement has a workpiece-supporting element; a securing device for readily releasably mounting the workpiece-supporting element at least indirectly on the table for temporarily positioning the workpiece-supporting element; and a gripping and holding device installed in the empty stage for grasping the workpiece-supporting element, removing the workpiece-supporting element from the table, moving the workpiece-supporting element into a workpiece-supporting working position in the empty stage and holding the workpiece-supporting element in its working position.
