Abstract: A press is provided with gripping rails for moving workpieces in work stations. The press is provided with a motor and a shaft moved thereby, on which shaft cams are mounted. Swing levers follow the shape of the cams, and connecting tabs direct the movements of swing levers toward driving movements of the gripping rails. At least two rollers are rotatably mounted on swing levers. The rollers run on the shaft cams. At least one of the two rollers is pressable with zero play against one of cams by a pretensioning device.

Abstract: An arrangement is used for transferring workpieces through a succession of machining stations of a press, a simulator or similar machining or tool-setting machine. Two parallel transport rails are spaced at a distance from one another and can be moved by motors horizontally in their longitudinal direction, vertically up and down and optionally horizontally toward one another. The motors are arranged on one traverse respectively, the transport rail being hinged to the traverse. Between the transport rails and the motors arranged on the traverse, a compensating guide is provided for the horizontal movement of the transport rails. The compensating guide has at least two struts and a double-armed lug with three hinge points, each of the struts being mounted on the traverse side in a hinged manner at one point respectively.

Abstract: A transfer device in a simulator or a press has two transport rails which extend in the press passage direction and which can be moved in two or three axes. One or several carrier rails are detachably mounted on each transport rail. For a tool change, the carrier rails can be deposited on depositing supports of the sliding table. Between the transport rails and the carrier rails, locking and fastening devices are provided which permit a coupling-uncoupling operation which is caused by the movements of the carrier rails in the axes.

Abstract: In order to reduce the transfer times of sheet metal parts in a press installation, the fastening point of the devices holding the sheet metal parts can be adjusted on a running carriage, which can be driven horizontally in a running rail, in the direction of the travel movement by an adjusting device.
