摘要: 兩軋輥在軋制區的軋制力不對稱性是偏心軸類零件兩輥楔橫軋軋制成形的一個顯著特征.利用有限元法計算了偏心軸類零件楔橫軋成形中軋制區軋制力差,并對其影響因素進行了較為系統全面的分析,闡明了影響因素對軋制力差的影響機理,最后還綜合分析了各影響因素對軋制力差的影響程度.Abstract: In the rolling procedure of eccentric shafts by cross wedge rolling, the non-symmetry of rolling force in rolling zone is a significant characteristic. The force difference in rolling zone of eccentric shafts during cross wedge rolling was calculated by finite element method and its influencing factors were systematically analyzed. The mechanism of influencing factors on the force difference was clarified. Finally the influence degree of each influencing factor was evaluated.
