Analysis of Cold Preforming Process for Hollow Fasteners with Thin Flange

Abstract:

This paper aims to study and detect the imperfects of the hollow fasteners with thin flange during cold forging process. In this study, the finite element analysis (FEA) based on 3-D DEFORM^TM software to investigate the plastic deformation behavior of the hollow fasteners with thin flange. The simulation results showed that there is a folding phenomenon, which is occurring in the forming process. As a result, it revealed that with using FEA, the imperfects of forming hollow fasteners with the thin flange can be correctly predicted. From that, the occurrence of defects can be effectively prevented in the actual fabricating process. Future work will include an investigation into the optimization of the mold geometric parameters during cold pre-forming process for hollow fasteners with thin flange by comparing the simulative and experimental results.
