摘要:

 建立了TB6钛合金筒形件旋压成形工艺模型,运用有限元软件对不同工艺参数下工件的变形过程进行了模拟,分析了工件在旋压过程中的受力和变形特性,并研究了减薄率(30%~45%)、变形温度(900~1050 ℃)、主轴转速(3~6 r·s-1)和旋轮进给率(1.0~2.5 mm·s-1)等工艺参数对旋压过程中等效应力、等效应变的影响规律。结果表明:变形温度和主轴转速对工件成形质量的影响较小,旋轮进给率和减薄率对成形质量的影响较大。随着旋轮进给率的增大,外径圆度精度呈V形分布;随着减薄率的增大,工件的最大等效应力和等效应变均随之增大。综合优选出的最佳的旋压工艺参数组合为:减薄率为30%、变形温度为1000 ℃、主轴转速为4 r·s-1、旋轮进给率为2 mm·s-1。

The spinning process model of TB6 titanium alloy cylindrical parts was established, and the deformation process of workpiece under different process parameters was simulated by finite element software. Then, the force and deformation characteristics of workpiece during the spinning process were analyzed, and the influence laws of process parameters such as thinning rate (30%-45%), deformation temperature (900-1050 ℃), spindle speed (3-6 r·s-1) and wheel feeding rate (1.0-2.5 mm·s-1) on equivalent stress and equivalent strain during the spinning process were studied. The results show that the deformation temperature and the spindle speed have little influence on the forming quality of workpiece, while the wheel feeding rate and the thinning rate have significant influence on the forming quality. With the increasing of the wheel feeding rate, the roundness accuracy of outer diameter shows V-shaped distribution, and with the increasing of the thinning rate, the maximum equivalent stress and the equivalent strain of workpiece increase accordingly. Thus, the optimal combination of spinning process parameters obtained by comprehensive optimization is the thinning rate of 30%, the deformation temperature of 1000 ℃, the spindle speed of 4 r·s-1, and the wheel feeding rate of 2 mm·s-1.
