A Case study for near net Shape – Flashless forging for full yoke (Sleeve Yoke OMNI)
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 4
Abstract
Forging is a metal forming process commonly used in industry. Forging process is strongly affected by the process parameters. In a progressive press forging process, an initial block of metal (billet) is compressed between two dies halves in each stage to produce a complex part. The shape of the initial billet is crucial in achieving the desired characteristics in the final forged part. The metallurgical property as well as the geometry of the final product are strongly dependent on the shape of initial work piece as well as on the perform shapes at each of the subsequent forming stages. The major issue, which restricts imparting large deformation to the billet are the tensile stress, which later results in cracking. Bulge is also undesirable from near net shape manufacturing point of view, as it will require secondary processing like trimming Traditionally, an experienced designer uses his or her expertise and design data handbooks for optimizing the initial billet shape. Design of the optimum preform for near net shape forging is a crucial step in the design of many forging products In this study, the same is arrived at using profile map, which is generated using the results of FE simulations of varying geometrical and processing parameters.It is shown that preform map offers a powerful tool for near net shape forging
