摘　　要：对棒材无模拉伸力能参数进行了试验研究，分析了棒材无模拉伸力能参数的影响因素及影响规律．结果表明：冷热源间距、断面收缩率、变形温度、拉伸速度、冷热源移动速度以及碳素钢材料的含碳量对无模拉伸力能参数都有不同程度的影响．In this paper,drawing force during rod dieless drawing is studied by experiment. The influence factor and influence law on dieless drawing are analyzed. According to the experimental results,it is found that the width between cooling and heating apparatus, moving speed of cooling-heating apparatus,deformation temperature,ratio of sectional reduction,drawing speed and the material,s carbon content have different influence on dieless drawing force.
