摘　　要：分析了钢管辊拔的特征，推导出辊拔时辊拔力的解析式。该解析解与实验结果较为吻合。以积分中值定理与水平力平衡条件确定了辊模压力。可供钢管辊拔计算时参考。Based on analysis of the characteristics of steel pipe roller die drawing process,the analytical equation for the drawing force during roller die drawing operation is derived.The analytical solution obtained via the equation was in close compliance with relevant experiment result.The roller die pressure is set up with the integral mid-value law and the horizontal force balancing condition.The data is referenceable to calculation concerning steel pipe roller die drawing process.
