  • Patent number: 5690026
    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.

  • 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: 5363684
    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.

  • Patent number: 5363683
    Abstract: A transfer press or similar forming machine is provided with a transfer device having holding devices for the gripping and transport of sheet metal parts. During the transfer movement of the sheet metal parts from one machining stage to the next, the sheet metal parts are deposited intermediately on an intermediate depositing device. The intermediate depositing device takes over a partial path of the transfer so that the movement of the holding devices is less than half the distance between the machining stages.

  • Patent number: 5048318
    Abstract: An intermediate depositing station between machining stages of a metal forming machine, having templates for supporting a sheet metal part from below which are adjustable in height, distance and oblique position relative to another sheet metal part. The intermediate depositing station has a mounting plate that is displaceable in a first horizontal direction with respect to a foundation. A first adjusting device is coupled to the mounting plate and is operable to displace the mounting plate horizontally. A carriage plate is coupled to the mounting plate and is displaceable in a second horizontal direction that is transverse to the first horizontal direction. A second adjusting device is coupled to the carriage plate and is operable to displace the carriage plate horizontally. A console is coupled vertically on the carriage plate. A third adjusting device is coupled to the console and is operable to lift and lower the console.

  • Patent number: 4932235
    Abstract: To facilitate a mounting of end areas of gripper rails having exchangeable parts, in a transfer press during a set up change, elements for coupling and uncoupling the exchangeable gripper rail parts are integrated into a constructional unit. This constructional unit includes separatable housing components in which an adjusting device is arranged in one of the housing components which has a slidable clamp bolt. The clamp bolt can be clamped behind a clamping surface in the other housing component. Guided along with the clamp bolt are centering bolts for aligning of the gripper rail parts with respect to one another and a guide bolt for the moving of a carriage located outside the constructional unit.

  • Patent number: 4924692
    Abstract: In a transfer press, the gripper rails consist of gripper rail parts located at the press and exchangeable gripper rail parts. In operation, the gripper rail parts must be rigidly connected with one another. For this purpose, a coupling element utilizing a rotary tightening device is inserted in one gripper rail part and has a tension rod which can be braced with T-shaped head behind a coupling surface of a gripper rail part located at the side of the press. Flange facings are machined into front faces of the gripper rail parts. These flange facings have flat surfaces which extend parallel to the direction of the lifting and lowering movement of gripper rail parts and the direction of the opening and closing positioning movement of a sliding table carrying exchangeable gripper rail part. The gripper rail parts are separated along the flat end surfaces of the flange facings and do not require longitudinal displacement to provide a separation gap.

  • Patent number: 4790960
    Abstract: A process for the stripping of cesium ions from an aqueous solution in which a precipitation agent is added to the aqueous solution and the resulting precipitate, containing the CS.sup.+ ions is stripped from the solution. Sodium or lithium tetraphenylborates, carrying electron-attracting substituents on the phenyl rings are employed as precipitation agent.

  • Patent number: 4170857
    Abstract: A facade construction made of plate-like construction elements having ground edge faces at which the elements are joined with one another without mortar. The plate-like construction elements have interior cavities, the cavities of superimposed construction elements forming through-going air passages connected toward the outside at least in the top and bottom portions of the facade. The ground edge faces form horizontal bearing-surfaces and vertical abutting-surfaces relative to adjoining construction elements. Between these horizontal bearing-surfaces and/or vertical abutting-surfaces of adjoining construction elements locking elements or elements for connection with the means securing the facade to a wall are arranged.
