摘要： The disclosure relates to an apparatus for compensating for such deformations as occur in operation in first and second clamping surfaces (52, 53) intended for a toll (9) in a press (1), the clamping surfaces being reciprocally moveable towards and away from one another in order to move a first and second part of the tool (9) towards and away from one another, and the first and second tool parts have a first and second abutment surface (54, 55, respectively) for abutment against the first and second clamping surface (52, 53, respectively) and the deformations cause uneven pressure in at least on contact region (56) between the tool (9) and the clamping surfaces (52, 53). According to the present invention, there is disposed, in at least one contact region (56) between a clamping surface (52) and an abutment surface (54), a power unit which, on activation, is operative to press, away from the clamping surface (52) located in the contact region (56) at least a part of the abutment surface (54) of the tool (9) located there.
摘要翻译：本公开涉及一种用于补偿在用于在压力机（1）中的收费（9）的第一和第二夹紧表面（52,53）中发生的这种变形的装置，所述夹紧表面可朝向和远离彼此之间以便将工具（9）的第一和第二部分彼此移动并远离彼此移动，并且第一和第二工具部分具有第一和第二邻接表面（分别为54,55），用于抵靠第一和第二夹紧表面（52,53），并且变形在至少在工具（9）和夹紧表面（52,53）之间的接触区域（56）上引起不均匀的压力。根据本发明，在夹紧表面（52）和邻接表面（54）之间的至少一个接触区域（56）中设置一个动力单元，该动力单元在启动时可操作地压迫位于所述接触区域（56）中的位于所述工具（9）的邻接表面（54）的至少一部分的夹紧表面（52）。

摘要： A hydraulic press for deep drawing has mutually reciprocating clamping rings (6, 13) for fixedly clamping a sheet metal blank (5) with a predetermined force. The clamping rings (6, 13) are operated each by their cylinder (9, 14). The press has a tool (4) for forming the sheet blank (5), and a power unit (10, 11, 16) for generating a relative movement between, on the one hand, the clamping rings (6, 13) and, on the other hand, the tool (4). During the forming phase, the working volumes of the cylinders (9, 14) are interconnected to a common volume to which there is further connected a pressure maintenance device with a pressure sensor (22), a regulator valve (23) and a pump (28). The piston areas of the cylinders (9, 14) are suitably equal.
摘要翻译：用于深拉的液压机具有用于以预定的力固定地夹紧金属板坯（5）的相互往复的夹紧环（6,13）。夹紧环（6,13）由其气缸（9,14）各自操作。压力机具有用于形成板坯（5）的工具（4）和用于在夹紧环（6,13）之间产生相对运动的动力单元（10,11,16）另一方面，工具（4）。在成形阶段期间，气缸（9,14）的工作容积互相连接到公共容积，在该容积中，进一步连接有压力维持装置，压力传感器（22），调节阀（23）和泵 28）。气缸（9,14）的活塞面积适当相等。
