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.

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).

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.

Abstract: An orienting station provided particularly for press systems has a receiving device which is carried by a rod-type transmission. This rod-type transmission is supported on drive units of a driving device. The drive units are disposed in a stationary manner. The rods of the rod-type transmission are rigid and their lengths cannot be changed.

Abstract: A transfer system, particularly for a press facility, has a guiding device on which workpiece holding devices are longitudinally displaceably disposed which belong to two different groups. The longitudinal displacement takes place by way of a driving device which is carried at least partially by the guiding device.

Abstract: An energy absorber having an essentially air-tight covering which surrounds a filling material and is provided with at least one feed line. In order to improve the absorption characteristics, the feed line is connected to a vacuum source and the energy absorber is coupled with a valve device as well as with a pre-crash sensor system.

Abstract: 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.

Abstract: A transfer press has sliding tables each assigned to one or several press stations and which, for the mold change, can be moved preferably laterally out of the transfer press. The sliding tables (or the molds disposed thereon) have receiving devices for the tooling which includes at least workpiece-specific holding devices of a transfer system which is used for transporting parts from press station to press station. For moving the sliding tables out of the transfer press, the receiving devices are positioned in separate depositing areas preferably provided laterally next to the molds. When the receiving devices are changed from their operative position taken up in the transfer system into the deposited position, the holding devices are swivelled by the receiving device which has a swivellable construction itself or a separate transfer device.

Abstract: In a large-part transfer press, several forming stations are arranged below a common slide in order to minimize cost. The bedplate construction has two longitudinal or basic supports. On each support, one bedplate per forming station is transversely placed and fastened as required. Driving of the slide takes place by two mutually independent head pieces which, depending on the number of stations, are arranged side-by-side at a distance. Each of the head pieces spans only one forming station.

Abstract: A press arrangement has a sliding tables which carry molds and are provided in the press stations. Holding systems on the sliding tables or on the molds are used for receiving holders which are arranged on the intermediate station arranged between the press stations. The holders carry templates for the intermediate deposition of workpieces. In addition, the holders have receiving devices for receiving workpiece-specific parts of the transfer system, particularly suction frames. During the mold exchange, the intermediate depositing station is operated such that it receives the suction frames by way of the associated holders. Thereafter, the holders are deposited on the holding systems.

Abstract: A transfer device for press systems has cross traverses with at least one suction unit swivellably held thereon. The suction unit has an electric drive for coordinating the swivel movement with the transfer curve (horizontal and vertical movement) to be travelled. As may be required, two or more suction units can be independently swivellable on a cross traverse. A retrofitting and retooling of existing cross traverses can be carried out by the replacement of non-swivellable suction units used so far by swivellable suction units. Other changes on the mechanical structure of the transfer device are not required.

Abstract: A transfer device 41 provided particularly for multistation presses 1 has a holding device 46, 47 which is carried by several rods 53, 54, 55; 83, 84, 85 and which can be swivelled in space and positioned by means of the rods 53, 54, 55; 83, 84, 85. The rods 53, 54, 55; 83, 84, 85 are preferably connected with linear driving devices 61, 62, 63; 86, 87, 88 which therefore jointly act upon the holding device 46, 47. In the case of an embodiment having six degrees of positioning freedom, three of the rods 53, 54, 55; 83, 84, 85 are applied to a first hinge point 49 of the holding device 46, 47. By means of their other ends, these rods 83, 84, 85 define a triangle. Of the remaining three rods 53, 54, 55, two 53, 54 are applied to another hinge point 56 and a third 55 is applied to a hinge point 57 situated away therefrom which again defines a triangle together with the other two hinge points 49, 56. In addition to the simple workpiece transfer, such a transfer device 41 permits complicated positioning tasks.

Abstract: A multistation press has a three-axis transfer provided with transport rails onto which carrier rails are placed. The carrier rails carry grippers for the workpieces. During the tool change, the carrier rails are deposited on corresponding receiving devices of the sliding table. The transport rail is at first moved to deposit a first carrier rail connected therewith on the receiving device. Then the transport rail is separated from the carrier rail and is moved to bring a second carrier rail still connected therewith to the receiving device. The receiving device receives the second carrier rail in the immediate vicinity of the first carrier rail, whereby two carrier rails overlap and are spaced closely side-by-side. The receiving device is then laterally swivelled away. The carrier rails are deposited on the receiving device without the aid of driving devices operating between the transport rail and the carrier rail.

Abstract: A transfer device is provided particularly for multistation presses and is arranged between two working stations. The transfer device has a suction bridge which extends transversely with respect to a transfer direction and which is guided on its ends by two control arm gearings synchronously along a predetermined transfer curve. The control arm gearings are formed by control arms or rods which are connected on the end side with the cross traverse and which, on their respective end situated away from the cross traverse 46, are held in preferably vertically aligned linear axles, in which case the control arms, in respective pairs, enclose the same angle with one another. By the targeted controlling of the linear axles, almost arbitrary transfer curves can be travelled within the scope of the range of the transfer device. All linear axles are directly supported on a stationary frame whereby a high stiffness and precision is achieved even at high accelerations.

Abstract: A press with several press stations is provided for serially machining larger sheet metal parts. A transfer unit transports workpieces through the press stations which are arranged behind one another in the machining sequence. The transfer unit has a first section constructed as a three-axis transfer and a second section constructed as a cross-traverse transfer. The three-axis transfer has a pair of mutually parallel gripper rails with gripper devices which, by way of a lateral feeding movement of the gripper rails can be engaged with and disengaged from the workpieces. The cross-traverse transfer has a pair of mutually parallel transport rails which are connected with one another by cross-traverses provided with gripper devices for the workpieces. The cross-traverse transfer has parking positions between individual press stations in which the cross-traverses remain during the operation of the press stations.

Abstract: In the case of transfer presses and similar metal-forming machines, transfer devices must be provided for the transport of the sheet metal parts through the metal-forming stages. The lifting and lowering movement should be freely programmable, yet, a drive for the lifting and lowering movement is to be permitted which is free from play. This is achieved by the use of servo motors or similar motors with a hollow-shaft rotor and high-resolution position generators for the direct application on the transfer device, in which case the hollow-shaft rotor of each of the servo motors is provided with a spindle nut which, interacts with a spindle which is fastened on the transfer device in a non-rotatable manner.

Abstract: A transfer press or similar press installation is provided with a press frame including press supports, a press bed, and headpieces, these press parts being rigidly connected with one another by turnbuckles. The press installation includes slides and a transfer device, which are movable by driving devices. Longitudinal traverses are provided which extend along the length of at least the working stages. The press supports are arranged in front of and behind the working stages, and the longitudinal traverses are placed on these press supports. The longitudinal traverses are provided with guides which interact with guides mounted on the slides for the bearing of the slides which move up and down. As a result, a stable and cost-effective construction of the press installation is achieved while supports in the central working areas are omitted.

Abstract: A multistand press or similar press facility for the forming of sheet metal parts, is provided with bedplate, press stand and several press slides driven by the press drive for tool top parts interacting with tool bottom parts. Gearings for deflecting the rotating movement of the motor drive into the upward and downward movement of the press slides are arranged between press stands which each form a pair of stands, and are disposed opposite one another, and above the introduction of force into the press slides. Two gearings are provided for the respective pair of stands of two press slides. This make it possible to drive the press slides assigned to a pair of press stands from one press stand area.
