摘要： Die Erfindung betrifft ein Verfahren zum Herstellen von Hohlprofilen mit über ihre Länge unterschiedlichen Querschnitten. Die Hohlprofile werden aus einem ebenen einteiligen Blechzuschnitt (5, 6, 7) im Gesenk geformt, wobei durch ausgerundete oder abgerundete Längsschnittkanten (8a, 8b, 9a, 9b) in den Übergangsbereichen (8, 9) für Materialüberschuß oder Materialmangel gesorgt wird, so daß es beim Umformen nicht zu Materialausdünnungen oder Materialverdickungen in den Übergangsbereichen (8, 9) kommt.
摘要翻译：本发明涉及一种用于制造中空型材沿其长度不同的横截面的方法。所述中空部分是一个平坦的单件式金属板坯料（，6,5 7）形成在所述模具中，其中，由半径或圆滑的纵截面边缘（8A，8B，9A，9B）在过渡区域（8,9）被设置用于多余的材料或材料的缺陷，没有材料变薄或材料的增厚在过渡区域（8,9）中的形成过程。

摘要： The invention relates to a bending device for thin-walled metal pipes (R), comprising a straight pipe guiding device (1), and a contiguous core template (2) that can be swiveled with respect to the pipe guiding device (1) and that comprises a clamp bar (3). The bending device is further provided with a mandrel with a mandrel tip (4) that is flexible in the zone of the core template (2), and a mandrel shank (5) contiguous to and firmly linked with said mandrel tip (4), said mandrel shank being axially fixed in the pipe guiding device (1). The aim of the invention is to provide a bending device that allows to completely support the inside of the metal pipe (R) to be bent in the respective area of bending during the bending process. To this end, the flexible mandrel tip (4) that consists of a radially incompressible solid elastomer cylinder extends only across the initial section of the bending arc where the process of bending takes place. In order to pull the metal pipe (R) to be bent over said mandrel tip (4), it is clamped over a short length by means of a spherical grip holder (7) that can be inserted in the metal pipe (R) in the zone of the core template (2). Said grip holder (7) is free to move in the swivel zone of the core template (2) with respect to the mandrel tip (4) and is connected to a tensioning device (6) that is configured as a return element.

摘要： The invention relates to a bending block for a bending device and to a bending method for tubes, especially tubes that have a large diameter-wall strength ratio and are to be bent with a small radius, e.g. in the order of the diameter of the tube. To this end, a bending block (5, 6) is used, a packet (6) of spring elastic metal sheet plates (6a, 6b) being affixed to the rigid head (5) of said block. In order to improve the flexibility of the bending block (5, 6) while preserving good support properties, all plates (6a), with the exception of the outer plates, have window-like recesses (6c).
