Roll-forming or bending machine

Abstract

A roll-forming or bending machine (1) is provided for forming an angled or rounded and simultaneously tapered hollow body or similar workpiece from a material blank. The roll-forming or bending machine (1) has at least one tapered roll (2) and at least one counter element, between which a forming pressure can be applied to the material blank. The one counter element has an elastic surface and is constructed as a bending table (3) for supporting the material blanks, so that the one or more rolls (2) apply the forming pressure on the material blank on the bending table (3). The bending table (3) is guided so that it can move in the longitudinal direction and can rotate about a rotational axis (5), and the one or more rolls can move perpendicular to the longitudinal direction, allowing a change in the relative position of the roll (2) and rotational axis (5) of the bending table (3) caused by a rotational movement of the bending table (3) to be compensated. Because the roll-forming or bending machine can eliminate the need for a roll with separately supported roll sections and because the roll necessary for forming the material blank can have a relatively small roll minimum diameter, rounded and simultaneously tapered workpieces can also be shaped or bent with a relatively small radius.
