FIELD: plastic working of metals, possibly manufacture of double-curvature articles in creep mode.
SUBSTANCE: apparatus includes shaping chamber with working organs forming single-row modules; hydraulic drives; units for providing differential degree of said drives; normalizing devices. The last include screw gages with step motors mounted in single-row modules of working organs. Communication circuits of hydraulic drive include phase mains of power hydraulic cylinders, phase mains of return hydraulic cylinders and mains for communicating four-phase systems with pressure and drainage source. Constant-pressure main lines and phase main lines are mutually communicated through hydraulic distributors and other aggregates of hydraulic systems.
EFFECT: enhanced reliability of controlling, simplified program control, enlarged assortment of shaped products.
