螺旋焊管成型輥的分析
Analysis of Forming Roll for Spiral Weld Pipe
-
摘要: 為了消除螺旋焊管成型過程中壓痕等缺陷,提高焊管質(zhì)量,延長成型輥壽命,分析了螺旋焊管在成型過程中,三輥與管壁不發(fā)生相互滑動(dòng)的情況下,即在純滾動(dòng)的理想工作狀態(tài)下,三輥工況的共性和特性與輥面形狀;探討最接近理想狀況的輥面形狀,并就目前生產(chǎn)中存在的問題提出解決方案。Abstract: The analysis focuses on the common and respective working conditions and the profile of the three forming rolls during the forming process of the spiral weld pipe and under the precondition that there is no relative slipping between the said three rolls and the pipe surface, and the rolls are turning in a theoretical state. The analysis is aimed at finding out the best roll profile so as to reduce the rolling-caused quality defects of the pipe like roll mark, improve pipe quality and increase service life of the roll. In addition, proposals are put forward for current problems concerning the operation.
