A n a -p r ü c h e 1. Vorrichtung zum Ausgleich eines auf einen Stössel einer hydraulischen Presse wirkenden Momentes unter Verwendung zweier den Stössel in seiner unteren Lage abstützenden Anschlagglieder, dadurch g e k e n n z e i c h n e t daß die Anschlagglieder (13','141) auf einer im Pressengestell (" i 1 ) seit - cr, ge"*'iilirt("ii #"1 - livoneinander derart angebracht sind, daß beim Aufsetzen des Stössels (31) allein auf den Anachlaggliedern dessen .%,hrung frei von einem Moment ist und daß die Traverse von dem Stösoel mindestens während des Zurücklegens eines zur Bearbeitung eines Werkstückes (38) dienenden Weges entgegen der Wirkung einer insbesondere in ihrem Iluborgan (44) wirkenden Gegenkraft zu verschieben ist. 2. Vorrichtung nach Anspruch 1, dadurch g e k e n n z e i c hn e t , daß das Huborgan der Traverse (42) ein hydraulischer Arbeitszylinder (44) ist, der mit einer Druckmittelquelle (311) und mit einem Druckregelventil (46) verbunden ist 3. Vorrichtung nach Anspruch 1 oder 2, dadurch g e k e n n -z e i c h n e t , daß bei einem mit mindestens zwei voneinander unabhängigen Ziehkissen (23',23") ausgerüsteten Presse die Traverse (42) zwischen einem Stützorgan (231, 2311) und einem Arbeiteorgan (221, 2211) eines Ziehkissens angeordnet ist. 4. Vorrichtung nach Anspruch 3, dadurch g e k e n n z e i c hn e t , daß das Arbeitsorgan für das Ziehkissen (231, 2311) ein hydraulischer Arbeitszylinder (221, 2219 ist, der mit einem Überdruckventil (50) und über ein Rückschlagventil (48, 49) mit einem Vorratsbehälter (32f) verbunden ist. 5. Vorrichtung nach Anspruch 4, dadurch g e k e n n -z e i c h n e t , daß der Arbeitszylinder (221, 221f) des Ziehkissens (23', 2311) mit einem Steuergerät (51, 53) verbunden ist, mit welchem er mit dem Vorratsbehälter ( 321) nach Belieben zu verbinden und nach Belieben davon zu trennen ist. 6. Vorrichtung nach einem der vorhergehenden Ansprüche, dadurch g e k e n n z e i c h n e t , daß die Traverse (42) an ihren Enden je einen nach unten ragenden und im Pressenständer (211) geführten Führungssehaft (25'. 261) aufweist, in dessen Bereich oben auf der Traverse die Stellspindeln (131, 141) aufzusetzen sind. 7. Vorrichtung nach einem der vorhergehenden Ansprüche, dadurch g e k e n n z e i c h n e t , daß das Anschlagglied als Stellspindel (138.149 ausgebildet ist, die mit für ihre axiale Verschiebung ausreichendem axialem Spiel in einer am Pressengestell (11) fest angebrachten und einen Formachluas mit der Stellspindel ausschliessenden Führungsbüchse (111, 121) längs verschiebbar gelagert ist und auf der eine Stellmutter (151, 161) aufgeschraubt ist, die sich auf seiten des Stössels (31) auf dermührungsbüchse mindestens in dessen unterer Lage abstützt. A n a p r ü che 1. A device for balancing a force acting on a plunger of a hydraulic press torque using two the ram in its lower position supporting stop members, characterized g e k ennzeichnet that the stop members (13 ',' 141) to one in the press frame (" i 1) since - cr, ge" * 'iilirt ("ii #" 1 - are attached to each other in such a way that when the ram (31) is placed on the anchoring elements only, its.% rotation is free of a moment and in that the traverse of the Stösoel is to be moved at least during the return setting a serving for the machining of a workpiece (38) path against the action of a force acting in particular in its Iluborgan (44) counter-force. 2. device according to claim 1, characterized g e k ennzeic hn et that the lifting member of the cross member (42) is a hydraulic working cylinder (44), which is connected to a pressure medium source (311) and with a pressure regulating valve (46) 3. apparatus according to claim 1 or 2, characterized g e k hen -zeichnet that at one with at least two independent drawing cushion (23 ', 23 ") equipped press is the cross-member (42) disposed between a support member (231, 2311) and a Working member (221, 2211) of a die cushion . 4. Apparatus according to claim 3, characterized g e k ennzeic hn et that the operating member for the die cushion (231, 2311), a hydraulic working cylinder (221, is 2219 with a pressure relief valve (50) and via a check valve (48, 49 is) connected to a reservoir (32f). 5. device according to claim 4, characterized g e k hen -zei seframe that the working cylinder (221, 221f) of the die cushion (23 ', 2311) having a control device (51, 53) 6. device according to one of the preceding claims, characterized g e is connected, with which it is to separate the reservoir (321) at will and to connect at will thereof. k ennzeichnet that the cross member (42) at each of its ends a projecting and downwardly in the press stand (211) guided Führungssehaft (25 ', 261) has in the region of the top of the cross member, the adjusting spindles (131, 141) are set up. 7. device according to one of the preceding claims, characterized g e k ennzeich net, that the stop member as Stellsp indel (138.149 is designed, which is longitudinally displaceable with sufficient axial play for its axial displacement in a guide bushing (111, 121) which is fixedly attached to the press frame (11) and which excludes a form axis with the adjusting spindle, and on which an adjusting nut (151, 161 ) is screwed on, which is supported on the side of the plunger (31) on the dermührungsbüchse at least in its lower position.
