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.

Apparatus for supporting workpieces in a multistage press

For the exchange of tools in a press, the tools, including their associated gripper rail sections, are moved out of the press on a sliding table having a gripper rail support. To ensure that the gripper rails do not block access to the tool, the gripper rail support is adjustable in height. This permits lowering of the gripper rails sections to the extent that access to the tool is unimpeded.
