发明名称 Device for bending or curving hollow-section strips
摘要 A device for bending hollow-section strips (12) with clamping and guiding jaws (20, 21). A bending support (1) is provided, which consists of two bending support parts (2, 3) that engage between clamping and guiding jaws (20, 21). Bending support parts (2, 3) are independent of the clamping and guiding jaws (20, 21), which can be adjusted in the bending plane relative to the clamping and guiding jaws (20, 21). One bending support part (2) is mounted on a support (4) and the other bending support part (3) can be shifted, relative to the bending support part (2) that is mounted on the support (4), in a direction (arrow 5) that is perpendicular to the bending plane, whereby a movable bending support part (3) is under the action of a spring (9), which urges it away from the bending support part that is mounted on the support (4). Thus, the bending support (1) is automatically adjusted to an effective width that corresponds to the width of the hollow-section strip (12). For intermediate transport of the hollow-section strip (12), the clamping and guiding jaws (20, 21) need not be moved away from the side walls of the hollow-section strip (12).
