METHOD FOR THE OPERATION OF A MOTOR-DRIVEN HAND-HELD PRESSING APPARATUS, AND HAND-HELD PRESSING APPARATUS

摘要

The present invention relates to a method of operating a motor-driven portable pressing apparatus (1). In the above method, one or more pressing jaws 6 are moved to a closed pressing position until a predetermined pressing force is reached or a given amount of time has elapsed, where the pressing jaws are moved, for example, to the return of the plunger 5 It is automatically released by movement. The release operation may be cut off from the intermediate position before reaching the start position to start the next pressing process. In order to interrupt the release operation, a determination of movement and / or time and / or pressure determined during the pressing process and associated with the intermediate position is detected or automatically released at each intermediate position based on the measurement during the next pressing process And stored. The present invention also relates to a method for the sensor to confirm whether or not the pressing force has been reached. A motor-driven portable pressing device including a pressure sensor for sensing the pressure of the hydraulic medium in the hydraulic cylinder is also described.
