Numerical Simulation Analysis of the Cold Bending Forming Technology Based on DEFORM

Abstract:

In this paper, the accurate numerical simulations using the DEFORM-3D software are carried out in terms of the cold bending pipe technology. Correspondingly, the changes of state variables are gained, such as the stress, the strain, the material deformation speed, the damage severity and so on. Meanwhile, the important technical parameters concerned with the quality of pipe bending formation like the speed of the punch press, the friction coefficient and the friction types are comprehensively analyzed. Thus, it can be realized in practice to control and optimize the quality of the bent pipe production
