摘要: 介紹了預應(yīng)力高剛性液壓冷拔管機的結(jié)構(gòu)、特征,進行了拔管時的力學分析。通過試驗及長期的生產(chǎn)實踐,證明了該冷拔管機技術(shù)可靠。Abstract: 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.
