    三輥液壓定心裝置在穿孔機上的應(yīng)用

    Application of Hydraulically-driven Three-roll Centering System of Pipe Piercing Mill

    • 摘要: 介紹了穿孔機三輥液壓定心裝置的結(jié)構(gòu)及工作原理。該裝置以特制的雙行程液壓缸為動力,在無縫鋼管穿軋生產(chǎn)過程實現(xiàn)抱桿、抱管和打開3個動作,保證了鋼管穿軋過程軸向拋管的配合要求。生產(chǎn)實踐表明,該裝置完全能夠滿足無縫鋼管穿孔工藝要求,可在相關(guān)機組上推廣應(yīng)用。

       

      Abstract: Described are the structure features and work principle of the hydraulically driven 3-roll centering system(steadier)of the piercing mill.The system,powered by a specially designed dual-stroke hydraulic cylinder,is capable of the three major movements,i.e.,roll-closing to the bar,roll-closing to the shell and roll-opening,so as to ensure the proper axial delivery of the shell during the pipe piercing process.The actual operation result shows the said system is able to fully meet the piercing process requirements of seamless steel tubes,being worthy to be used on similar mills.
