Simulation and Investigation of Three Roll Bending Process using FEM Method and ABAQUS Software

Cylindrical as well as conical cross-section structural parts are widely used in industrial applications worldwide. Such parts are produced from metal tube using many manufacturing methods. ۳-roller conical bending process is one such process. In this process first the metal tube in specified blank shapes are given static bending in the rollers. Then the rollers are driven using motors for bending of the tubes under dynamic condition. During bending reaction forces will be there on the rollers. Forces acting on the rollers during the process are transmitted to the machine frame at the roller supports. In the paper an analytical model is developed for the prediction of force during the stage of dynamic bending. The model consists of various parameters like material parameters and geometrical parameters. Effects of various material and geometrical parameters are studied in the present paper. The present work can give in sighting the process and can be helpful to the designers as well as to the researchers working in the area of metal forming.
