  • Patent number: 7484922
    Abstract: The invention relates to an articulated arm transport device which is especially provided for the automation of large component transfer presses. Said articulated arm transport device is characterized by a kinematics and design that do not require any additional clearance between the press rams and pillars and that permit an introduction or extraction of workpieces even with a small clearance between the upper and lower tool. The articulated arm transport device is mounted above the workpiece transport plane on the press stands. The articulated arm part linked with the cross-member is shorter than the articulated arm part and makes a pivoting movement substantially above the common pivot. A lifting and/or pivoting movement can be carried out by means of controlled lift drives that are functionally linked with transmission means.

  • Patent number: 7040853
    Abstract: A transfer system provided, in particular, for multi-stage presses for large components is distinguished by a favorable design with a low moving mass and allows large transporting steps. By the regulation of 2 stationary drives both in the direction of rotation in relation to one another and in the rotational speed, it is possible to realize all desired traveling curves in one plane. A straightforward construction makes possible a cost-effective, modular solution for a highly dynamic transfer system.

  • Patent number: 6968725
    Abstract: The invention proposes a transporting apparatus for transporting single or double workpieces through processing stations of presses, in which apparatus up to 9 degrees of freedom are integrated in the transporting system. Necessary changes in position for, for example, feeding into dies can take place directly by way of the transporting apparatus. It is possible to dispense with intermediate set-down locations or orienting stations.

  • Patent number: 6715981
    Abstract: A transport system provided in particular for large-component transfer presses is distinguished by a design with a low width and, nevertheless, permits large transport steps. By controlling two drives in the direction of rotation in relation to each other, all desired travel curves in one plane can be realized. As a result of the simple construction, a cost-effective solution is achieved for a highly dynamic transport system.

  • Patent number: 6510786
    Abstract: The invention relates to a hydromechanical drive system for at least one press ram of a cutting and/or forming press, at least one drive cylinder being connected to a following kinematic chain. This kinematic chain is designed in such a way that a complete ram stroke, i.e. a downward motion and an upward motion, is effected during a single piston stroke in only one direction. In addition, the proposed drive system has mechanical controlled synchronization.

  • Patent number: 5584205
    Abstract: A transport system for transporting workpieces through machining stations of a press device. The transport system includes at least one independent transport device dedicated to each machining station, the transport device being effective for receiving and transporting a workpiece in at least one of a 2-axial and a 3-axial transport motion. The transport system includes a longitudinal transport device for effecting a horizontal longitudinal motion of the workpiece in a transport direction of the workpiece and having a horizontally extending extension arm for transporting the workpiece between machining stations. The extension arm includes guides, and a transport slide for transporting the workpiece in the transport direction. The transport slide is disposed on the guides for being longitudinally movable thereon and has coupling device thereon for coupling one of a suction beam and a gripper arrangement to the extension arm for effecting a reception of the workpiece by the longitudinal transport device.
