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： Press driving modules are provided to permit a standardized press design. The presses of a press line are equipped with always identical press driving modules, and the pressing force of the presses is varied only by the adaptation of the number of press driving modules. The press driving modules each contain two driving devices, respectively, that interact parallel or in series and have different characteristic curves. In particular, they have different maximal traveling speeds and different maximal forces. They can also have a different design with respect to their positioning capability and path resolution. This concept permits not only a standardization of presses of different performance classes within a press line but, beyond that, the largely free definition of characteristic path-time curves of the slides, and thereby finally also a freer design of workpieces, particularly of vehicle body parts.

摘要： A hydraulic drawing system for a press is provided for controlling a blank holder. The blank holder can be moved by at least one hydraulic cylinder-piston unit which has at least one pressure chamber. By way of a connection line, the pressure chamber is connected directly with a control block provided for controlling the movements of the at least one cylinder-piston unit. At least one storage element for storing pressure for the at least one cylinder-piston unit is connected by way of a connection line with the control block and, by way of another connection line at least one valve device is connected with the control block. The connection lines extend in each case at least approximately completely within the respective components.

摘要： A multistation press has several slides which can be moved up and down and which are equipped with tools for forming workpieces. The press a transport arrangement for transporting the workpieces within and/or between the stations. At least one cross traverse for holding the workpieces, in its resting condition, is aligned at least approximately perpendicularly with respect to the transport direction of the workpieces. The cross traverse is held at its two ends in each case a lever arrangement and can be oriented in the space. A length compensating device is arranged on at least one of the two ends of the cross traverse to change the overall length of the cross traverse between its two ends. The length compensating device has an exterior tube element, which is mounted at one end of the cross traverse on the one lever arrangement, and an interior element which is displaceably arranged inside the exterior tube element and which is mounted at the other end of the cross traverse on the other lever arrangement.
