摘要: Aiming at the concavity defects in cross-wedge rolling (CWR) process, one new method named as twice closed–open joint CWR was presented to improve use ratio of material axle parts. The included three stages: first closed rolling, second and last open rolling. To investigate flow this 3D finite element model (FEM) established. process pump spindle part simulated using established FEM. formation, law metal materials end were studied. In addition, experiments carried out. results simulation agreed with tests well. proved that can decrease extent ratio.
