Claims

[Claims for Utility Model Registration] 1 Consists of a press table 1 that is movable within the main shaft of the press, and the press table 1
At the top there is a guide bar 5 for lateral guidance of the lower tool, which is movable in the direction of movement of the press table 1.
at least two freeform forging presses having
In the changing device for lower tools of Tsusha plate 10, 11,
12, 13 tightening stepped portions 10a, 11a, 1
2a and 13a, these pressure plates are guided in the tool changing direction transversely to the moving direction of the press table 1 like the tools, and are movable simultaneously with the tools. Also, the pressure plates 10, 11, 12, 13, which are arranged in each case on both sides of the tool on the press table 1, are pressed by means of fixed clamping devices 16-19. By moving downward, the stepped portions 10a, 11a are tightened.
, 12a, 13a. 2 Adjacent lower tools each have one common tightening stepped part 11 with a T-shaped cross section.
Pressure plate 11 having a, 12a
, 12 are attached, and the pressure plates 11, 12 are attached to the corresponding stepped portions 4a, 12 of the tool via these tightening stepped portions 11a, 12a.
8a, 9a and an outer pressure plate 10, for moving the tool together with the pressure plates 11, 12 in the exchange direction.
1 each acts to press the sides of 13
Either two displacement devices 6, 7 or, if there is a tension-resistant connection between the pressure plate and the tool, one displacement device with a tensioning effect is provided. Scope of claims for utility model registration No. 1
Replacement device as described in section. 3. On both sides of the press table 1 there are devices 16 to 19 for guiding and tightening the pressure plate.
Lock block 1 fixed for support of
4, 15 are arranged. 4. The tightening devices 16 to 19 consist of horizontally brakeable locking pins 17 with wedge-shaped heads 17a, which are movable vertically with lateral locking pins provided on the pressure plate 12. 4. The changing device according to claim 3, which is insertable into the recess 12b and is adapted to generate a downward clamping force. 5. One double-acting displacement cylinder 16 in each case, in which the locking pin 17 is guided into the lateral legs of the U-shaped locking blocks 14, 15 and is machined into the lower locking block of the locking pin via a crosspiece 18. The changing device according to claim 4, which is connected to the piston rod 19 of the utility model. 6 Locking blocks 14, 15 are designed as lateral guides for the movable press table 1, and tightening devices 20,
21. The switching device according to claim 3 of the utility model registration claim.
