Abstract (en)

[origin: EP3593983A1] The fluid dynamic plant for the controlled drive of the ram of a press comprises: a pushing piston (20) housed sliding in a sliding seating (30) of a press and that divides it into a stem-side chamber (30A) and a thrust-side chamber (30B); a first pump (1) of a pressurized fluid which is driven and/or controlled by a first servomotor (11) functionally connected therewith; an accumulator group (6) of pressurized fluid which is fluid-dynamically connected alternatively to the first pump (1) or to the sliding seating (30); a distributor group (3) for alternate fluid-dynamic connection of the first pump (1) to said sliding seating (30) or of the first pump (1) to the accumulator group (6), a power generator group (34) being interposed between the latter and the sliding seating.
