NUMERICAL MODELING OF A HYBRID ASYMMETRIC ROLLING AND BENDING PROCESS

Conference Paper


Abstract


  • Aerospace and automobile industries demand bend sheets with different radii of curvature and in some cases, even the sheets of continuously varying radius of curvature are also required by them. Forming of such parts require a flexible manufacturing process to closely control the radius of the curvature being formed. This work proposes a hybrid forming process that combines asymmetric rolling with incremental bending to form bend sheets with improved mechanical properties. In the proposed hybrid process, thin metal sheets are asymmetrically cold rolled and then bend by a punch placed after the rolling mill, in the direction of sheet flow. The work presents the numerical simulation of the hybrid process and explores the relation between the hammering amplitude and its frequency on the radius of curvature. Besides, the significance of different parameters on the bend sheet being formed is also investigated using analysis of variance (ANOVA). The results show that the velocity ratio and hammering amplitude are the paramount factors in the proposed hybrid process, and these parameters greatly influence the radius of the bend. Simulation results also indicate that the radius of bend can be augmented by decreasing velocity ratio, hammering frequency, and effective amplitude.
