预应力高刚性液压冷拔管机的设计

Design of Prestressed High-rigidity Hydraulically-operated Cold-drawing Pipe Mill

介绍了预应力高刚性液压冷拔管机的结构、特征，进行了拔管时的力学分析。通过试验及长期的生产实践，证明了该冷拔管机技术可靠。

Described here are the structure and features of the prestrssed, high - rigidity, hydraulically - operated cold - drawing pipe mill as well as the mechanical analysis of the mill during pipe drawing operation. Relevant experiments and long - term operation practice of the mill have shown the technologically reliability of the mill.
