| titleOfInvention | Method for pressing a workpiece with a predetermined pressing force |
| abstract | The invention relates to a method for pressing a workpiece (4) with a predetermined pressing force by means of a forming tool (3) which is coupled to an electric motor (2) via a transmission, in particular a screw transmission (6), wherein the screw transmission (6) converts a rotational movement of a drive shaft (8) of the electric motor (2) into a translational movement of the forming tool (3). The method comprises the following method steps: -accelerating the electric machine (2) in the screwing direction to a predetermined maximum rotational speed; -running the electric motor (2) at a maximum rotational speed until the drive shaft (8) of the electric motor (2) has completed a predetermined number of revolutions; -reducing the rotational speed of the electric machine (2) to a predetermined reduced rotational speed; -operating the electric motor (2) at a reduced rotational speed until a rise in the pressing force exceeding a predetermined threshold value is detected by a measuring unit (12) connected downstream of the electric motor (2); -shaping the workpiece (4) while continuously detecting the pressing force by means of the measuring unit (12) until a predetermined pressing force is reached. |
