Abstract (en)
The method and the system for controlling a cylinder actuator (115) of a ram of a press comprises: a motor group (101) that actuates a pumping group (102); a ram that is hydraulically connected by a hydraulic system with the motor group (101) and/or pumping group (102) and that is movably actuated between a first stroke of approach to a piece to be worked, a second working stroke of the piece to be worked, and a third return stroke from a worked piece; an accumulator (105) being connected with a chamber (113) on the rod side of the cylinder actuator (115), a pressure reducer (108) to control the pressure inside the accumulator (105), in which the motor group (101) connected with the pumping group (102) controls the approach stroke and/or the working stroke and/or the return stroke.
