摘要： 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.

摘要： 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.

摘要： 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.

摘要： A transfer press provided with a transfer device, having transfer units provided with cross members (37) for which the length is shorter than the width of a tool. The transfer units (29 to 32) are arranged completely between the processing stations or stages, are mounted on the crown or head piece, and are not provided with elements extending beside the tools or between supports of adjacent processing or press stations. Thus, the full width spanned by the press supports can be used for the tools. In addition, tools can be used which are provided with guides, effective between the upper tool and the lower tool, particularly in the side region. The work pieces are handled solely by means of the openings, freed by the tools and pointing counter to the transporting device, wherein no element of the transfer device extends past the side limits of the tool. The cross members (37) are preferably not supported at the ends (38, 39) by their transfer units (29 to 32), but at the locations (57, 58) at a distance thereto, thus permitting a higher operating speed.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
