Abstract (en)
The invention is a press (1; 101; 201; 301; 401; 501; 601) for processing a component (C), comprising a ram (2) suited to be subjected to a movement in a substantially longitudinal direction (X) against the component (C) in order to perform the processing cycle, the press (1; 101; 201; 301; 401; 501; 601) comprising a supply unit (20) suited to be connected to an electricity supply network (E) for the conversion of electrical energy into mechanical energy and a kinematic mechanism (5) associated with the ram (2) and suited to transmit the movement to the ram (2). Said press (1; 101; 201; 301; 401; 501; 601) comprises a hydraulic circuit (30; 230; 430) provided with a hydraulic motor (31) and supply means (32; 232; 432) suited to supply a hydraulic fluid for the hydraulic motor (31), said supply means (32; 232; 432) being operated by the supply unit (20) and the outlet (14) of the hydraulic motor (31) being connected to the kinematic mechanism (5).
