Qualitative Physical Modeling and Experimental Study on Forging Method with Horizontal V-Shaped Anvil
Heavy axial forgings made by conventional methods have obvious fibrous tissue in the axial direction, leading to the anisotropy of mechanical properties. The forging method with horizontal V-shaped anvils (HVA) is introduced to control fibrous tissue flow direction, to improve the anisotropy of mechanical properties of axial forgings. The forging method is superior to the common flat anvils (FA) forging method in inner stress states, metal tissue, overall properties and geometrical shapes of forgings. Qualitative physical simulation and pilot production for the HVA forging method are conducted, verifying the fact that the HVA forging method is an effective process to control the mechanical properties of axial forgings. The HVA forging method may reduce the anisotropy of the mechanical properties of axial forgings and increase their uniformity by 5~50%.
