Abstract:
A method is provided having the following steps: a) providing a drive-out device which has a drive-out punch that is actuated via a hydraulic cylinder; b) positioning the drive-out device between two adjacent wheel discs of the rotor such that a longitudinal axis of the drive-out punch is flush with the receiving groove of the blade to be driven out; c) adjusting a maximum pressure which can be applied to the hydraulic cylinder; d) extending the drive-out punch such that the drive-out punch presses against the blade root of the blade to be driven out with increasing pressure; e) reducing the pressure as soon as the pressure has reached the maximum pressure; and f) cyclically repeating the steps d) and e) until the blade has been removed from the receiving groove. A drive-out device is further provided.

Claim (Index 9):
A drive-out device for carrying out a method as claimed in  claim 1 , with an electrohydraulic pump, which is connected to an oil tank, a hydraulic cylinder, which is connected to the electrohydraulic pump by way of a switchable valve, a driving-out ram, which is operatively connected to a piston rod of the hydraulic cylinder in such a way that hydraulic cylinder is moved by the piston rod in a direction of a longitudinal axis as soon as the hydraulic cylinder is subjected to a pressure by the electrohydraulic pump, and a pump controller, which is designed in such a way that the pump controller switches the switchable valve to reduce the pressure as soon as the pressure has reached a preset maximum pressure, and in such a way that pump controller switches the switchable valve to increase the pressure as soon as the pressure has reached a preset minimum pressure, (p min ), or as soon as a predetermined time period has elapsed.
