Abstract

The present invention relates to a forge rolling device (1) for the bending forge rolling of a component (2), in particular of a component blank, having a first forging roll (10) with a first axis of rotation (R), and a second forging roll with a second axis of rotation, wherein each of the forging rolls (10) has, on its surface (11), a forge rolling contour (12) that runs at least partially around its axis of rotation (R), said forge rolling contours (12) corresponding to one another, in order to form a component (2) passed between the forging rolls (10) in a passage direction (D). This forming can be bending with or without cross-sectional change. In this case, the forge rolling contours (12) are configured so as to bend the component (2), passed between the forging rolls (10), in at least one direction transversely to the passage direction (D) of the component (2), at least by means of one subregion (13) of the forge rolling contours (12). The present invention also relates to a method for the bending forge rolling of a component (2) and to a component (2) produced with the method according to the invention.
