  • Patent number: 5001921
    Abstract: A transfer device permits different moving sequences of holding devices for the sheet metal parts which are to be moved through the metal-forming machine. The holding devices are fastened to carriages. The carriages are cam-guided, in which case a first carriage carries out a transfer movement from a working stage to an idle stage while taking along a sheet metal part. The return movement is interrupted in an intermediate position during the deforming operation of the sheet metal parts. A second Carriage carries out a transfer movement from the idle stage to a working stage and a return movement which is temporarily interrupted in an intermediate stage. The vertically extending motional parts of curves are used for the picking-up and depositing of sheet metal parts in working stages; the extended lowering movement is used for the depositing of the holding devices on sliding tables which can be moved into the press.

  • Patent number: 4680954
    Abstract: For avoiding collisions between the grippers (5) adapted to be moved out of the idling stage area and the grippers (4) disposed fixedly at interchangeable gripper rail partial sections (1) and work tool parts, the grippers (5) which are adapted to be moved out of the idling stage area, are raised into an upright position. The grippers (5) and the rotary adjusting drive (10) for the uprighting are adapted to be moved out of the idling stage area on a carriage (18-gripper mounting support) by way of an adjusting means (13) at the exchangeable gripper rail partial section.

  • Patent number: 4641515
    Abstract: An intermediate storage in a press in which intermediate storages are to be provided within the area of idling stages thereof. The intermediate storages include storage templates matched to the shape of the bottom side of the workpieces which are adapted to be liftable in the vertical direction by way of lifting means. The lifting means may thereby act on the storage templates in the sense of a lifting movement, for example, by way of intermediate members displaceable by a motor-driven spindle, which act on the storage templates in the sense of a lifting movement by way of counter-abutment surfaces disposed at the ends of the storage templates.
