Influences of Key Forging Parameters on Cold Orbital Forging of Thin Parts with High Circular Ribs

Abstract

AbstractIn this paper, a cold orbital forging process is proposed to manufacture thin parts with high circular ribs. First, a FE model was established for the numerical process analysis. Then a verification experiment was performed to verify the validity of the FE model developed above. By using the FE simulation method, the influences of several forging parameters on the cold orbital forging of thin parts with high circular ribs were investigated. The results show that effective strain can be obviously improved by increasing feed velocity of cavity die, but has less change with different friction factors. Synchronism of metal flowing between the inner rib and the outer rib can be improved by decreasing feed velocity of cavity die and friction factor. Moreover, the circumferential metal flowing degree can be slightly reduced by increasing feed velocity of cavity die and friction factor.KeywordsCold orbital forgingThin part with high circular ribsMetal flowing analysis
