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.

In a manufacturing method of a thickness-varied metal plate, first, a cut plate is manufactured by cutting a metal plate having a constant plate thickness into a predetermined shape. Next, the thickness-varied metal plate is manufactured by rolling the cut plate using a processing machine including a pair of work rolls. Here, a radius of one of the pair of work rolls is varied in a circumferential direction and an axial direction. Accordingly, the thickness-varied metal plate manufactured by rolling the cut plate using the processing machine has a plate thickness varied in two different directions orthogonal to a plate thickness direction.

A production method for an elongated semi-finished product. A continuously fed wire is rolled by a rotating roller. Along its circumference, the roller has a first segment with a roller profile that rolls a profile into first sections of the wire, and also has a second segment without a roller profile that is rotated contact-free relative to the wire. During the rolling of the profile, the speed of the roller is adjusted in such a way that the speed of the roller profile is the same as the speed of the wire. During the contact-free rotation, the speed of the roller is adjusted in such a way that a length of the wire corresponding to a prescribed length of the second section passes the roller contact-free. A semi-finished product having the first section and having the second section is cut off of the shaped wire.

A stretch-rolling device and a stretch-rolling method for pressure-forming workpieces by rolls. The stretch-rolling device includes a pair of work-rolls with two rolls, which can each be rotated about their roll axes and form a roll gap between them. The rolls implement a plurality of stages in an axial direction, which are set up for stepwise deformation of the workpieces as the workpieces pass through the stages successively. A manipulator with a plurality of gripping devices, which are arranged on a working side of the pair of work-rolls, are set up to grip the workpieces at an assigned stage to guide the workpieces through the roll gap in a feed/retraction direction. A support is arranged to temporarily support the workpieces in cooperation with the manipulator to transfer the workpieces to another gripping device, which is preferably an adjacent gripping device of the next higher stage.
