Estimating the term…
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. It is conversely possible for the compensating elements each to be pressed stepwise to a position compensating the detected deviations during the deforming operation. It is possible to use (piezoelectric) actuators to exert the resistance force and/or to move the compensating elements. The invention further relates to a device with which this compensation method can be performed.
Method for compensating deviations in a deforming operation between two beams of a press, comprising of:
A device for compensating deviations in a deforming operation between two beams of a press, the device comprising at least one compensating element arranged at a suitably chosen location in the press, a detector for detecting the deviations during the deforming operation, an electromechanical mover for moving the at least one compensating element relative to the beams during the deforming operation, and a controller connected to the detection means for controlling the moving means.
