摘要：

为解决旋轧工艺在大进给比下材料隆起和堆积的问题，提出了一种采用行星布置的辊柱旋轧加工工艺。首先,根据辊柱在空间的运动轨迹及管坯为半无限体的假设，建立了辊柱旋轧过程中辊柱与管坯的接触方程；依据坐标转换原则，得到辊柱与管坯接触区在动坐标系各坐标面下的投影面积；利用钢球压入空间半无限体时成形区的平均压力与变形区单位接触压力近似相等的假设，建立了辊柱旋轧数学模型。其次，基于ABAQUS/Explicit平台建立了辊柱旋轧三维数值模型，改变进给比f、减薄量tp和送进角β，进行多工艺参数数值模拟。结果表明：旋轧力三向分力的理论计算结果与有限元模拟数据具有较高的吻合度，提出的辊柱旋轧三维数值模型计算方法可以为旋轧工艺与设备设计提供参考。

In order to solve the problem of material swelling and accumulation under a large feeding ratio in the spinning process, a roller spinning manufacturing process with a planetary arrangement was proposed. First, according to the trajectory of roller in the space and the assumption that the tube blank was a semi-infinite body, the contact equation between roller and tube blank during the roller spinning process was established, according to the principle of coordinate conversion, the projected area of the contact area between roller and tube blank under each coordinate plane of dynamic coordinate system was obtained, and the mathematical model of roller spinning was established by the assumption that the average pressure in the forming zone was approximately equal to the unit contact pressure in the deformation zone when the steel ball was pressed into the semi-infinite body of space. Secondly, based on the ABAQUS/Explicit platform, a three-dimensional numerical model of roller spinning was established, and the numerical simulation of multiple process parameters was carried out by changing feeding ratio f, thinning amount tp and feeding angle β. The results show that the theoretical calculation results for the three-dimensional components of spinning force are in good agreement with the finite element simulation data, and the proposed calculation method of the three-dimensional numerical model for the roller spinning provides a reference for design of spinning process and equipment.
