The first lever arm is connected at a first end thereof or between the first and a second end to the first drive unit, and at the second end thereof to the second drive unit. The second lever arm is rotatably connected at a first end thereof to the second drive unit, and is movably connected with a second end thereof to the crossbar. In addition, at least one energy-storing element is provided for each movement arm, which energy-storing element is formed and arranged in such a way that its force or a force component thereof points in the acceleration direction of the crossbar with or without. In an embodiment c1, a second fastening region is provided on the fastening unit, and the energy-storing element is connected directly or indirectly with a first end thereof to the second fastening region, and is fastened on a second end thereof at a specified region of the movement arm. In an additional or alternative embodiment c2, the energy-storing element is fastened with a first end to the first lever arm and with a second end thereof to the second lever arm.

The invention relates to a device for transporting workpieces in three axes within a transfer press which has a plurality of tool stages, wherein the device has two mutually opposite transport bars formed in one piece which are movable in the three axes and which remain in the transfer press during an automatic or partially automatic tool change, and an adapter rail per transport bar, wherein each adapter rail is releasably fastened to the associated transport bar. Also provided is at least one tooling per adapter rail, wherein each tooling is directly releasably fastened to the associated adapter rail. Alternatively, at least one tooling rail is provided to which the tooling is indirectly releasably fastened. Here, only adapter rail with tooling or adapter rail with tooling rail and tooling are moved out of the transfer press during the automatic or partially automatic tool change.

A system of a separable frame for presses and press frames (1), the respective press frame (1) comprising uprights (2) and a head piece as an upper cross connection (3) and a press table as a lower cross connection (4), which as structural units form a closed frame that absorbs static and dynamic forces for any required functions of a press such as the drive of a ram used for forming with tools. The uprights (2) are attachable laterally or longitudinally to the cross connections (3, 4) by non-positive or non-positive and positive joining geometries (5) and releasable connector (5.1). The proposed press frames (1) have a reduced vertical deflection (v2) compared to press frames joined by tie rod bracing (6).
