- the invention is therefore an object of the invention to provide for a press of the type mentioned with upwardly movable table or plunger, a transfer device for the gradual displacement of workpieces and adapt, with the most economical and effective processing of the workpieces is possible.
- the press defined at the outset is characterized in that the transfer device can be moved or formed to move the workpieces with the table or plunger and can be actuated during the downward movement of the table in the direction of a displacement of workpieces.
- a further advantageous embodiment of the invention can provide that the transfer device with its drive relative to the table is adjustable so that the area of the tool located on the table for a change from the side is accessible. Thus, a tool change despite the attachment of the transfer device to the table is easily possible.
- a favorable embodiment may provide that the adjustable transfer device is mounted with its drive on a rail guide approximately horizontally movable and adjustable in particular in its extension direction. If the transfer device is moved out of the range of use with the gripper rail (s) in its direction of extent, the tool area of the press becomes easily accessible from the side.
- a further or additional embodiment can provide that the transfer device with its drive is adjustable transversely or at right angles to its extension upwards or downwards or to the side for releasing the area for the tool change.
- the transfer device with its drive is adjustable transversely or at right angles to its extension upwards or downwards or to the side for releasing the area for the tool change.
- the gripper rail or can Gripper rails of the transfer device and the movable holder releasably and be stored on a shelf or console on the press.
- the gripper rails do not need to be adjusted when changing tools or repairs, but it is sufficient to move their drive, which is easier and also requires less space.
- the gripper rails having transfer device may be mitbewegbar with the table or plunger or it may be provided an additional stand for which this device can join the table movements via suitable coupling means, whereby the table receives a lower weight.

- Fig. 7 is a side view of the press according to the invention, wherein the transfer device for moving the workpieces with the gripper rails are in their position of use in the region of the table and the lower tool.
- a designated as a whole with 1 press is used to form m several steps their final shape obtaining workpieces 2, which are transported by means of a generally designated 3 transfer device stepwise to individual deformation points of the press 1, as for example from DE 10th 2004 023 525 B4 is known in principle.
- the transfer device 3 for stepwise shifting has m the embodiments two in the feed direction according to the arrow PF1 in Figure 4 in the feed direction for the feed and in the opposite direction for a return movement back and forth movable gripper parts 4 for detecting the workpieces 2 having gripper rails on, the m known manner for detecting the workpieces and moving m feed direction and then back to initial position are adjustable, with a lift-off movement of the workpieces takes place from the respective deformation point.
- the press 1 has a table 6 provided for upward and downward movement, which is designed as a ram or stator plate and is provided for receiving a shuttle table 7 with at least one part of the respective tool, in the exemplary embodiment of the lower tool.
- a table 6 provided for upward and downward movement, which is designed as a ram or stator plate and is provided for receiving a shuttle table 7 with at least one part of the respective tool, in the exemplary embodiment of the lower tool.
- To transmit the pressing force of this table 6 is movable from bottom to top against a fixed counterpart 8.
- the transfer device 3 arranged to move the workpieces 2 with the movable up and down table 6 and the shuttle table 7 with lower tool mitbewegbar or is formed and during the downward movement of the table 6 away from the counterpart 8 in the sense of a displacement of workpieces 2 m whose feed direction can be actuated.
- the time m the table is moved from the upper pressing position to a lower position for operating the transfer device 3 and the further movement of the workpieces 2 can be exploited.
- the transfer device 3 is slidably guided on vertical supports 9 and coupled via driver 10 with the table 6 or detachable, so that the table 6 has a lower load to carry, but still the transfer device 3 the Can join table movement to transport in the lowered position, the workpieces 2 or to be able to transport further.
- Workpieces 2 can be made during the further lowering of the table 6, so that during the subsequent upward movement of the table 6 and the lower tool, the gripper rails 5 are again movable away from the workpieces 2 in the m Fig. 5 position shown.
- the press 1 can thus work 3 m shorter cycle times with the transfer device movable with the table 6 than if the device 3 is not taken along by the table 6.
- the transfer device 3 for the workpiece transfer with its drive relative to the table 6 is adjustable such that the area of the tool located on the table 6, for example, for a change of this tool or accessible from the side for repair.
- the transfer device 3 - detached from the gripper rails 5 are moved on rail guides 11 out of the press area.
- the adjustable transfer device 3 is mounted with its drive on the rail guide 11 approximately horizontally movable and adjustable in the direction of extension or feed direction of the workpieces.
- the area on the side of the press 1 where the tools are located becomes free for replacement or repair.
- FIG. 2 shows how the transfer device 3-without the gripper rails 5 detached from it-is moved away from the table 6 so that the position shown in FIG. 6 can be moved.
- the press 1 for deforming workpieces 2 m in several steps has a transfer device 3 with gripper rails
- the table 6 supporting the one or more lower tools of the press 1 is movable up and down to generate the pressing force, and the transfer device 3 is connected to this table
