Abstract: A method for operating a hydraulically operated hand-held device is provided. The hand-held device includes a hydraulic pump, a moving part, a fixed part and a return valve with an associated valve seat. The moving part can be displaced into a working position by a build-up of hydraulic pressure produced by filling a hydraulic chamber with hydraulic medium from a storage chamber using the hydraulic pump. The moving part can be automatically moved back from the working position into an end position by opening the return valve, if a predetermined working pressure is reached. The hydraulic pressure acting upon the return valve for triggering a movement of the moving part into the end position is increased independently of reaching the predefined working pressure.

A balance piston is arranged in the piston in addition to an overpressure valve. Up until a switch-off pressure is reached, i.e. throughout the pressing process, the balance piston closes a connection opening and a return flow channel.

Abstract: 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.
