  • Patent number: 11695124
    Abstract: A method and a device for producing bipolar plates for fuel cells. A bipolar plate is formed by joining an anode plate to a cathode plate, wherein the anode plate and the cathode plate are formed by forming a substrate plate. In order to provide a cost-effective and automated method, it is proposed that a plate already provided with a reactive coating or catalyst coating, which is transported, automatically driven, via a transport device from the forming device to the joining device, is used as substrate plate.
    Type: Grant

  • Patent number: 11123787
    Abstract: A transport device for the transport of workpieces in a workpiece transport direction in a press, which has a carrier rail, which is mounted, via a lifting carriage and a rocker rotatably mounted on the lifting carriage, on a vertically running upright of the press. In order to enable a flexible workpiece transport, it is provided that, on the carrier rail, workpiece grippers are mounted on at least two transport carriages, which each have their own drive mechanism in order to move the transport carriages with the workpiece grippers along the carrier rail independently of each other.

  • Patent number: 10369621
    Abstract: In a forming system in particular for metallic workpieces (31, 32) with several forming stations (21-23) a transport device (1) is provided with one or more rails (13) on which carriages (141, 142) can be moved. In a conventional mode of operation of the rails, it is provided that two carriages (141, 142) on the same rail (13) are moved by a varying distance relative to each other during the transport of a respective workpiece (31, 32) from one forming station (21-23) to another forming station (21-23), namely in particular are driven towards each other or away from each other with their distance relative to each other being increased or decreased. New production sequences can thereby be provided.

  • Patent number: 7234912
    Abstract: The invention relates to a device for the transport of work pieces with at least one transport device (T1, T2) which can be installed on a frame (14) of a processing device (P) and which has a transport bar (15) which is kept moveable in X- and Y-direction. To increase the rigidity of the device, it is suggested that the transport bar (15) be kept moveable with at least two parallelogram servo drives (PL1, PL2).
