摘　　要：目前,液压支架的立柱千斤顶缸筒大多采用热轧管加工方式,来料一般为钢管毛坯,需要经过多道工序,加工周期长,严重影响加工效率。本文通过液压支架千斤顶的受力分析和计算,结合冷拔钢管的力学性能,判断各规格的千斤顶缸筒使用冷拔钢管替代热轧管的可行性。At present,most of the column jack cylinder tubes of hydraulic supports are processed by hot-rolled pipes,and incoming materials are generally steel pipe blanks,which need to go through multiple procedures,and the processing cycle is long,which seriously affects the processing efficiency.Based on the force analysis and calculation of the hydraulic support jack,combined with the mechanical properties of cold-drawn steel pipes,this paper judged the feasibility of using cold-drawn steel pipes instead of hot-rolled pipes for jack cylinder tubes of various specifications.
