    試論偏心成型立輥

    DISCUSSION ON ECCENTRIC VERTICAL FORMATION ROLL

    • 摘要: 通過(guò)分析現(xiàn)有非偏心成型立輥孔型存在的各種弊端,提出了偏心成型立輥孔型這一新概念。詳細(xì)介紹了偏心成型立輥的結(jié)構(gòu)特點(diǎn)、作用、偏心位置與偏心距的確定以及實(shí)驗(yàn)結(jié)果等。偏心成型立輥不僅可以增大管坯的變形量,減少軋輥的磨損,延長(zhǎng)成型輥的使用壽命,而且還便于調(diào)整,能夠提高焊管的質(zhì)量

       

      Abstract: Based on analysis of weakpoints of the traditional non-eccentric vertical formation roll groove,the new concept of eccentric vertical formation roll groove is put forward. Detailed in the paper are such aspects of the eccentric vertical formation roll as structural characterisitics, funtion, eccentric position and setting of eccentricity as well as results of relevant experiments. The eccentric vertical formation roll can not only increase deformation amount of the tube, reduce roll wear, prolong the service life, but also provide easy adjustment and better quality of welded pipes.
