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).

A transfer system, particularly for the transfer of workpieces in multi-station presses, includes several transfer modules, each of which has a workpiece holding device carried by at least one lever mechanism. Each lever mechanism transmits the adjusting movement of two mutually independent drives to the workpiece holding device. One of the drives is disposed in a stationary manner and the other drive is moved by the stationarily disposed drive.

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.

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.

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.
摘要:
A press is provided with gripping rails for moving workpieces in work stations. The press is provided with a motor and a shaft moved thereby, on which shaft cams are mounted. Swing levers follow the shape of the cams, and connecting tabs direct the movements of swing levers toward driving movements of the gripping rails. At least two rollers are rotatably mounted on swing levers. The rollers run on the shaft cams. At least one of the two rollers is pressable with zero play against one of cams by a pretensioning device.

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.

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.
