Three-Dimensional Bending of Profiles with Stress Superposition
Source abstract
Abstract
The paper shows a new method for three-dimensional bending especially of profiles. The bending process only works in one plane according to the machine geometry. To leave the two-dimensional bending plane, the profile cross-section is turned by an overlaid torsional moment. By this process very long symmetrical and asymmetrical profiles can be bent three-dimensionally without surface damage and the unwanted torsion of asymmetrical profiles can be prevented by means of a similar compensation moment. The paper focuses on the bending method which is realized in the new experimental setup. The device consists of a hybrid machine design of hydraulic and electrical drives, both numerically controlled. The new device realizes a new roll-bending method that uses 6 transportation rolls and also a roll-based bending head. The bending moment is applied in the profile by a transverse force driven by the bending head and a servohydraulic cylinder. The turning of the cross-section during the process is realized by a special machine design, making it possible to turn the guiding rolls and the bending rolls of the machine synchronistically.
