FIELD: process engineering.
SUBSTANCE: proposed device comprises bed with thrust rail, wedge arranged between said bed and thrust rail and mechanism of wedge lengthwise displacement drive composed of screw and nut. Stand stiffness is increased and transfer time is decreased by making skew ledge at wedge end with bore for screw of ledge drive, said screw being equipped with two washers with antifriction shims arranged on both sides of said skew ledge of the wedge and locking washers, bush, ledge and nut. Said screw has spline end to fit spline sleeve or reducer thereon while screw drive nut is cylindrical. Bed has two blind mutually perpendicular bores to receive cylindrical nut and wedge drive screw. Plate with inclined surface for ledge and seat for thrust rail is arranged between wedge and thrust rail. Bed has lubing bores, wedge being provided with lubing grooves communicated by bores while two grease cups are arranged at the bed.
EFFECT: higher quality of tubes and efficiency of rolling mill.
