ABSTRACT:
An apparatus for axially adjusting a bottom work roll of a plug mill to align the grooves of the top and bottom rolls. The apparatus includes a bottom roll chock having a pair of laterally extending members, each carrying a transverse, tapered wing shaped end portion. A pair of spaced apart adjustment assemblies are mounted on the plug mill housing adjacent the lower roll chock. A pair of tapered wedges is carried by each of the adjustment assemblies. The wedges are adapted to slideably engage and move the tapered wing shaped portions of the lower roll chock. A segmented tie bar having a manually rotatable turnbuckle is rigidly attached to lever arms carried by the adjustment assemblies. Rotation of the turnbuckle, which carries conventional left hand and right hand threads, causes identical outward or inward movement of the tie bar segments and lever arms which, in turn, causes like rotative movement of a gear train positioned within the adjustment assemblies resulting in opposite sliding movement of the pairs of tapered wedges. The movement of the tapered wedges against the tapered wing shaped portions of the roll chock causes selective inward or outward movement of the roll chock and axial movement of the bottom work roll.
