Abstract (en)

[origin: EP2093024A1] The electro-hydraulic pistol device (100) comprises: a first electric micro-motor (1 ), for setting in right-wise or left-wise rotation a threaded rod (2), respectively for engaging or disengaging the rod (2) from a rivet (3); a hydraulic system (4) in which a fluid (F) pushes a cursor (40), associated to the rod (2) for impressing thereon an axial translation which causes plastic deformation of a predetermined portion of the rivet (3), such as to block the rivet (3) to a corresponding wall (P); a second electric micro-motor (5), for commanding a piston (50) destined to compress the fluid (F). An electrical circuit (6) is associated to the above organs, which electrical circuit (6) is managed by a control unit (60), to which are connected: a first micro-switch (61) activated by the rod (2) for activation of the first micro-motor (1) in a right-wise direction; a second micro-switch (62), destined to be activated by a trigger (63) after deactivation of the first micro-switch (61), for activating the second micro-motor (5), first in a direction, for compressing the fluid (F), and then in another direction, for reducing the pressure of the fluid (F), as well as for activating, in phase relation, the first micro-motor (1) in a left-wise rotation; supply means (7) for the circuit (6) and the micro-motors (1, 5). The left-wise rotation of the first micro-motor (1) and the rod (2) proceeds as long as the trigger (63) is kept pressed.
