摘　　要：冷拔无缝钢管的壁厚偏差是评定其质量优劣的重要指标,而管坯中心孔的加工是减少壁厚偏差的重要保证.为了解决硬质材料管坯上难于打中心孔的问题,提出一种基于电弧式中心孔机的设计方法.介绍了该机的组成和原理.实际生产表明,该机减小了穿孔毛管壁厚偏差,提高了毛管的质量.Pipe thickness deviation of cold-drawn seamless steel pipe is an important index to evaluate the quality of pipe. Processing a tube center hole is an important guarantee for the reduction of pipe thickness deviation. In order to solve the problem of centering the hard material tube, this paper presents an arc hole center based on machine design method. The paper introduces the characteristics of the machine components and principle. The actual production shows that the machine reduces the pierced shell pipe thickness deviation, and improves the quality of the capillary.
