ABSTRACT:
A press which has a short ram stroke in which the ram is movable in a single plane in a working direction and return direction, particularly for high speed cutting presses, comprises, a press frame with a ram carried by the press frame which is supported by springs which are rigidly connected to the ram and to the press frame and hold the ram resiliently for movement in the working and return direction but rigidly in all other planes. The springs advantageously comprise at least two spring elements which are arranged substantially perpendicular to the direction of the ram stroke and may advantageously comprise sets of bar springs arranged on each of two sides of the ram and connected from the ram to the frame; leaf springs having lateral extensions which are arranged one above the other and connected between the ram and the frame or springs arranged in a network or pattern in the form of spiral spring assemblies or spring packs which permit the displacement of the ram in the working and return stroke but hold it rigidly in other planes.
