METHOD AND DEVICE FOR CONTROLLING AND ADJUSTING FORCES ON SERVO-ELECTRIC PRESSES

The invention relates to a method for controlling and adjusting forces on servo-electric presses comprising servoelectric tappet drives and/or die cushion drives and to a device for carrying out said method. The invention relates, in particular, to the use of the guiding wave functions for producing the part- and process-specific desired torque values and for producing the torque correction values based on various influence variables, together with temperature compensation of the torque factor in order to form the desired current value for the servo motors, for the translation-dependent torque calculation and/or a guiding wave-controlled functional unit for the acceleration-dependent first torque correction value and/or a guiding wave-controlled functional unit for the friction-dependent second torque correction value. In the devices, at least one current regulator, connected to a servo amplifier, receives the desired value of the control device which consists of a guiding wave-controlled desired value control device, guiding wave-controlled functional units and/or a functional unit for the temperature compensation of the torque factor and, according to control performance, a force control loop having a force or torque sensor.
