FIELD: press-forging plants. SUBSTANCE: proposed mechanized set includes group of dies mounted on under-press platen at two levels and actuating member made in form of disk. Actuating member is movable and turnable which is necessary for holding the blanks on second level die. Dies of first and second levels and disk are mounted on under-press platen along axis of delivery of blanks. Device for replacement of mechanized set of tools has table, platform, guides for motion of platform, under- press platen and motion mechanism. Mounted on either side of table are beams and at least two eccentric bushes. Beams and under-press platen as well as under-die platen and table are provided with profiles on their engageable surfaces forming detachable joints. Device is provided with two spindles mounted along axis of delivery of blanks; said spindles are mounted in passages of table for longitudinal reciprocating motion and rotary reciprocating motion. L-shaped connecting rods are mounted over contour of working zone on both sides of each spindle. EFFECT: extended field of application; enhanced efficiency. 3 cl, 6 dwg
