Abstract

See full text

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.
