An Investigation for the Performance of the Design of Hot Forging Die and Workpiece

Hot forging is a metalworking process in which metals are plastically deformed above their recrystallization temperature, allowing the material to retain its shape as it cools. In today's industry, performance of tools used during hot has always been subject interest. Although known that, tool life affects 10% design costs total budget, 80% production determined stages. For this reason, minimizing mechanical stress and changing die design, so optimize reduce cost, have attractive. study, finite volume analysis was performed on 31CrV3 steel using multi-stage forming closed Simufact Forming v16 software. 56NiCrMoV7 work X153CrMoV12 template blade raw material. article, 3 state variables, effective plastic strain, equivalent temperature were evaluated for two different designs processes such pre-forming, final forging, cutting. The results compared cost single dual dies. both designs, initial billet 1100-1200 ºC 100-110 ºC. Finally, comparative analyzes three variable parameters terms properties cost. main focus calculating based available subroutines incorporation designs. According obtained from simulation manufacturability product proven, effect changes workpiece investigated, revealed by evaluating profit rate.
