A press with crossheads interconnected by vertical pillars, at least one of said crossheads moving relative to the stationary crosshead which carries a sliding table with the lower die, the upper die being secured to the movable crosshead above. The stationary crosshead accommodates a rod and the drive of a pulling device connected with an auxiliary crosshead below, said auxiliary crosshead having vertical spindles with stops which interact with the adjacent movable crosshead at the beginning of radial compression of the tubular billet.

Press for pressing pipe fittings

The pipe bending machine of the present invention is adapted for mandrelless pipe bending with the simultaneous compressing of the pipe being bent to avoid thinning of the walls thereof. The invention can be used to best advantage when applied to bending large-diameter (1000 mm and over) steel pipes. The machine features the bending mechanism and the longitudinal travelling mechanism so interconnected by means of the members and disks that a braking moment is applied to the bending mechanism and, consequently, pipe upsetting occurs.
