Universal rolling machine

Abstract

The present invention relates to a universal rolling machine wherein a pair of left and right vertical rolls, which are positioned on axial centers that intersect axial centers of a pair of upper and lower horizontal rolls, are mounted coaxially within vertical roll chocks, and the vertical roll chocks are each arranged within a housing in a freely slidable manner along a direction of rolling of a material to be rolled. Assemblies each comprising a circular cylindrical nut and a screw are arranged on either side of the vertical roll chocks along the direction of rolling in spaces between the housing and the vertical roll chocks, as a movement mechanism for the vertical roll chocks. The provision of this configuration enables the use of conventional vertical roll chocks, ensures sufficient mechanical strength with respect to the reactive forces applied to the vertical rolls during the rolling, enables a reduction in costs, and also enables a significant shortening of the time required for replacing the rolls.
