试论偏心成型立辊

DISCUSSION ON ECCENTRIC VERTICAL FORMATION ROLL

通过分析现有非偏心成型立辊孔型存在的各种弊端， 提出了偏心成型立辊孔型这一新概念。详细介绍了偏心成型立辊的结构特点、作用、偏心位置与偏心距的确定以及实验结果等。偏心成型立辊不仅可以增大管坯的变形量， 减少轧辊的磨损， 延长成型辊的使用寿命， 而且还便于调整，

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.
