A new method for feasibility study and determination of the loading curves in the rotary draw-bending process
Source abstract
Abstract
A new computational methodology has been developed that enables to rapidly obtain feasible, close to optimal displacement curves for the control of some of the key tools, namely the booster and the pressure die. Considering the main geometrical data (thickness, external diameter, bending radius and bending angle) and the strain distribution in a draw-bending process, the algorithm generates the right correlation between the booster and the pressure die velocity curves. The development of the proposed method has been carried out with an explicit FEM commercial code and has been verified comparing the numerical output and the experimental results. In this paper, the effects of the variation of booster and pressure die displacement curves will be also highlighted.
