The machine for cracking a connecting rod comprises an electro press with an electric motor (400) for actuating an expandable element. The electro press comprises a first actuator part (410) and a second actuator part (430) arranged so that when the first actuator part is driven by the electric motor (400) from a first position to a second position,
(a) the first actuator part (410) is first driven by the electric motor (400) from said first position ( Fig. 12A ) to an intermediate position ( Fig. 12B ), without displacing the second actuator part (430), and
(b) subsequently the first actuator part (410) is further driven by the electric motor (400) from said intermediate position ( Fig. 12B ) to said second position ( Fig. 12C ), displacing the second actuator part from a non-expanding position to an expanding position. |
