Abstract:
The invention relates to a method for compensating deviations in a deforming operation between two beams of a press, comprising of arranging one or more compensating element at a suitably chosen location in the press, detecting the deviations and moving the compensating element(s) relative to the beams by (electro) mechanical means during the deforming operation such that the detected deviations are compensated. The compensating elements can be moved here to an over-compensating position prior to the deforming operation and pressed out of their over-compensating position during the operation by the load on the beam, wherein each compensating element exerts an adjustable resistance force on surrounding parts of the press. The compensating elements each can be pressed stepwise to a position compensating the detected deviations during the deforming operation. Piezoelectric actuators can be used to exert the resistance force and/or to move the compensating elements.
