为了实现轴类零件的轻量化,提出了一种不同材料层合轴楔横轧成形的新方法。42CrMo和Q235两种钢分别被用作层合轴的外层和内层,并对层合轴进行了楔横轧成形。利用有限元软件ANSYS/LS-DYNA对楔横轧不同材料层合轴成形过程进行了模拟分析,得出了42CrMo/Q235钢层合轴轧制过程中楔入段与展宽段的应变分布。结果表明:径向应变是影响层合轴轧制的主要因素;在楔入段时,界面对楔横轧层合轴的成形影响较小;展宽段的横向应变、径向应变、轴向应变的变化都很大,展宽段是层合轴界面结合的主要阶段。
In order to reduce the weight of shaft parts, a new method of cross-wedge cross-rolling forming with different materials was proposed. 42CrMo and Q235 two kinds of steel were used as the outer layer and the inner layer of the laminated shaft, and the wedge cross-rolled laminated shaft forming. The finite element software ANSYS / LS-DYNA was used to simulate the cross-shaft forming process of cross-rolled cross-wedges. The strain distributions of the wedging and broadening sections of 42CrMo / Q235 steel were obtained. The results show that the radial strain is the main factor that affects the rolling of the laminated shaft. In the wedging step, the influence of the interface on the forming of the wedge cross-laminated laminated shaft is small. The transverse strain, radial strain and axial strain The changes are large, widening section is the main phase of the laminated shaft interface.
