  • Patent number: 5566814
    Abstract: A press, multistation press or similar forming machine, avoids space problems when a sheet bar loader is used in the inserting area of the press as a result of the movements of the transport rails in three axes. The length which is the result of the length of the transfer movement of the transport rails and the required length of the guiding devices on these rails is included in the length of the press-side guides on which the areas of the transport rails which are away from the driving area for the transfer movement are disposed in the direction of the transfer movement.

  • Patent number: 5551275
    Abstract: A multiple stand press or similar press facility for the forming of sheet metal parts has a bedplate, several press stands, and a press slide 7 which can be moved up and down by the press drive via drive gear boxes and connection rods. Tools in progressive stations follow a drawing station. In order to be able to reduce the size of the press facility, the press slide extends along at least two stand areas, and the introduction of force takes place via the connecting rods into the press slide in the stand areas.

  • Patent number: 5473927
    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.

  • Patent number: 5388952
    Abstract: An arrangement for transferring sheet metal parts in a press installation, in which the sheet metal parts must be rotated with respect to their position in the next working stage. In addition, a collision between the sheet metal part and the tool during the transfer movement is avoided. During the transfer movement, the sheet metal parts are held on one traverse respectively which, on the end side, is disposed in bearing devices to be rotatable about an axis of rotation, and can be rotatably acted upon by a servomotor, a pressure cylinder or similar adjusting devices, such as a cam, and movement transmission devices.

  • Patent number: 5385040
    Abstract: A transfer device in a press line has traverses which are situated transversely with respect to the workpiece passage and can be adjusted in the horizontal and vertical direction, and which support sheet metal parts placed on them. The traverses are fastened on toothed belts are movable in guide strips on deflecting rollers by servomotors.

  • Patent number: 5383348
    Abstract: In a press, an individual press, a multistage press, a multistand press and similar forming facilities, transfer devices are provided for the transport of sheet metal parts in the machining stages. These transfer devices have guide strips which can be lifted and lowered in vertical guides on the press stands via adjusting devices. In each guide strip, toothed belts are arranged which are guided on deflecting rollers. The moving drive in the horizontal direction takes place from a motor-transmission device. As a result, a reduction of the mass of the movable structural members of the transfer device is achieved while the construction of the transfer device is modular.

  • 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.
