  • Patent number: 10160023
    Abstract: The drawing press according to the invention includes a support structure for supporting a metal sheet holder which is part of a tool and supported on the press frame via the support structure. The metal sheet holder is assigned a plunger with a die tool, whereas the plunger is moved by means of a plunger drive which includes a blocking position. The blocking position is obtained, for example, by a drive which, in the blocking position does not transmit any movement of the drive output to the driving servomotor. This can be achieved, for example, by an eccentric drive in the stretched position thereof. For performing the actual drawing stroke, the stamping tool is vertically movably supported. A carriage is raised or lowered by the press table by means of a table drive. As table drive, preferably a servomotor with a non-linear drive, such as an eccentric drive is used.

  • Publication number: 20080168910
    Abstract: An arrangement and a method for the programming of presses is described. The programming is performed interactively by an input of points on a display screen, wherein the points determine the movement strategy x? (?). For calculating the resulting plunger-time curve or plunger-guide angle-curve, preferably a Fourier analysis or, respectively Fourier transformation and back transformation of the curve determined by the input values is performed. In this way, a smooth and well executed kinematics plunger movement is obtained.

  • Patent number: 7287950
    Abstract: In a transfer arrangement and method for transferring a workpiece between first and second spaced locations along a guide rail with a carriage movably supported on the guide rail, a transfer arm is pivotally supported on the carriage and carries at its free end a workpiece holder which is accelerated by the carriage with the arm essentially stretched out in the movement direction out of, and decelerated into, the end positions, and, in an intermediate position, the carriage movement is slowed down or even reversed while the workpiece holder is moved along by a pivot movement of the arm.

  • Patent number: 6382400
    Abstract: A transport and position system, particularly for the workpiece transfer, has a lever mechanism between its driving motors and its output to carry out a step-up. The lever mechanism takes over the guiding as well as the driving of the carrier device which therefore forms the output of the lever mechanism. As a result of the step-up, high accelerations and decelerations can be achieved at the carrier device. Thereby, the mass inertia of linear guides for the bearing of levers and mass inertias of drives moved along play a substantially reduced role. While a high positioning precision can be achieved.

  • Patent number: 6374995
    Abstract: A positioning system (31, 32, 33, 34 35, 36), particularly for transporting and positioning workpieces, has a drive and force generating transmission device (47) by means of which a carrier device (41) can be moved and positioned. At least one force generating device (70) is connected to the drive and force transmission device (47), which force generating device (70) feeds into the drive and transmission system of the drive and force transmission device (47), an additional force used for compensating the weight of the drive and force transmission device and its moved parts and possibly of a workpiece, to the extent that this force manifests itself at the drives of the drive and force transmission device (47).

  • Patent number: 6374994
    Abstract: A transfer system, particularly for the transfer of workpieces in multi-station presses (1), consists of several transfer modules (14 to 19), which each have a workpiece holding device (28) which is carried by at least one lever mechanism (23). Each lever mechanism transmits the adjusting movement of two mutually independent drives (39, 44) to the workpiece holding device (28). One of the drives (39, 44) is disposed in a stationary manner, and the other is moved by the drive disposed in a stationary manner. This basic principle opens up many design possibilities.

  • Patent number: 6126582
    Abstract: A multistation press has a transfer device with cross traverses. The transfer device is set up for an automatic tooling change by providing that the cross traverses or the tooling held thereon are to be deposited on passive tooling receiving devices on sliding tables. This deposition takes place without the aid of transfer units in that a control device activates a height adjusting device independently of the other driving devices for the workpiece transfer such that the cross traverses are lowered to the passive tooling receiving devices.

  • Patent number: 6073551
    Abstract: A press has a transfer direction along which workpieces are transferred through machining stations by gripper rails. Two carriages are provided per gripper rail which can be moved transversely to the transfer direction toward and away from one another. Two parallel control arms are rotatably disposed on one carriage which, on the other end, are rotatably disposed on a support part. On the other carriage, a link is rotatably disposed which, on the other end, is applied at half length to a parallel control arm. The support part can be lifted vertically by the movement of the carriages.

  • Patent number: 5802967
    Abstract: An arrangement is used for transferring workpieces through a succession of machining stations of a press, a simulator or similar machining system or tool setting system. This arrangement has two spaced transport rails which are arranged parallel to one another and which can be moved by motors horizontally in a longitudinal direction thereof, vertically up and down and horizontally toward one another. Each individual transport rail is pivotally connected for a horizontal movement in each case by way of a coupling rod. Traverses are operatively connected by way of at least one of the coupling rods with one respective transport rail. The traverses can be moved by an additional transverse drive which is synchronously driven by the driving motors arranged in a closing box of the press for the horizontal movement of the transport rails toward one another.

  • Patent number: 5779025
    Abstract: An apparatus for three-dimensionally driving gripper rails in a multiple-pedestal press has raisable and lowerable guides for moving the gripper rails in a clamping and releasing direction in cross slide supports. The cross slide supports are movable in the clamping and releasing direction. The motion of the gripper rails in the clamping and releasing direction is brought about by a servomotor, which is secured at the level of the cross slide supports and which cooperates, with shaft portions extending from both sides thereof and embodied as spindles, with clasp nuts on the cross slide supports. In addition to the advantage of the direct drive for the clamping and releasing motion of the gripper rails, the region required by the tools in the working stages is utilized for accommodating the servomotors.
