Abstract
A stretch rolling method and a stretch rolling unit can roll out any gripping ends and uses the narrowest possible installation space. In the stretch rolling method, a workpiece is successively fed to at least two passes of a stretch rolling unit of a gripping device, wherein the vvorkpiece is rotated by 180° about an axis of rotation lying perpendicular to the main direction of extent of the workpiece between the first pass of the two passes and the second pass of the two passes.
Claims14
A stretch rolling method in which a workpiece (50) is successively passed to at least two passes (21, 22, 23, 24) of a stretch rolling unit (10) by means of a gripping device (30), wherein the workpiece (50) is rotated by 180°, about an axis of rotation (42) that lies perpendicular to the main expanse direction (54) of the workpiece (50), between the first pass (21, 22, 23) of the two passes (21, 22, 23, 24) and the second pass (22, 23, 24) of the two passes (21, 22, 23, 24), and wherein the gripping device (30) is displaced horizontally in the direction of the stretching roll (10) as well as vertically to the height of the second pass (22, 23, 23) before the second pass (22, 23, 24).
A stretch rolling method in which a workpiece (50) is successively passed to at least two passes (21, 22, 23, 24) of a stretch rolling unit (10) by means of a gripping device (30), wherein the gripping device (30) has two grippers (32) and the grippers (32) are changed between the two passes (21, 22, 23, 24), wherein the gripping device (30) is moved horizontally in the direction of the stretching roll (10) as well as vertically to the level of the second pass (22, 23, 24) before the second pass (22, 23, 24).
A stretch rolling unit (10) comprising two stretching rolls (20) that can be driven in opposite directions, having at least two passes (21, 22, 23, 24) and at least one gripping device (30), which can grip a workpiece (50) at a gripping end (52) and can be brought into at least a first loading position (61) and a first unloading position (62) for the first pass (21, 22, 23) and into a second loading position (61) for the second pass (22, 23, 24), wherein the gripping device (30) can be brought into a start-of-rotation position (63) and into an end-of-rotation position (64), and wherein the stretch rolling unit (10) comprises a rotation device (40) that can bring the workpiece (50) from the start-of-rotation position (63) into the end-of-rotation position (64), by rotating it by 180° about an axis of rotation (42) that lies perpendicular to the main expanse direction (54) of the workpiece (50), wherein the gripping device (30) can be moved horizontally in the direction of the stretching roll (20) as well as vertically to the level of the second pass (22, 23, 24) for the second pass (22, 23, 24).
A stretch rolling unit (10) comprising two stretching rolls (20) that can be driven in opposite directions, having at least two passes (21, 22, 23, 24) and at least one gripping device (30), which can grip a workpiece (50) at a gripping end (52) and can be brought into at least a first loading position (61) and a first unloading position (62) for the first pass (21, 22, 23) and into a second loading position (61) for the second pass (22, 23, 24), wherein the gripping device (30) has at least two grippers (32) having gripping geometries that are different from one another, wherein the gripping device (30) for the first pass (22, 23, 24) can be moved horizontally in the direction of the stretching roll (10) and also vertically to the level of the second pass (22, 23, 24) for the second pass (22, 23, 24).
