Intensive Shear Deformation in Billets During Forging with Specially Formed Anvils

Classification of forging schemes which involve intensive shear deformation in the billet have been proposed. An investigation of the stress-strain state in the billet during forging by anvils with slant has been done. The influence of such parameters as relative billet feed, anvil stroke, and anvil slant angle on billet strain state during the forging process has been determined. Recommendations of forging regimes in the form of such parameters as billet feed, anvil stroke, anvil slant angle, and billet rotation sequence have been made. The feasibility of forging a 41Cr4 steel billet with slanted anvils as a round shaft was confirmed experimentally, and the advantages of this new scheme over traditional flat anvil forging have been identified.
