十辊快开式矫直机辊缝自动调整系统的研究

Research on roller gap automatic adjustment system of ten roll quick open straightener

随着用户对钢管直线度的要求不断提高,六辊快开式矫直机的矫直精度已不能满足要求。中国重型机械研究院股份公司在六辊快开矫直机的基础上开发了十辊快开式矫直机,提升了热处理线钢管的矫直精度。十辊矫直机有五个上滑动梁,辊缝调整过程相对于六辊矫直机更加复杂,根据不同的调整参数需要不同的调整方案,本文根据矫直机的机械结构建立了单个矫直辊辊缝调整系统,并在此基础上建立主机上辊辊缝调整系统。

With the continuous improvement of user's requirements for the straightness of steel pipe,the straightening accuracy of the six roller quick open straightener can’t meet the requirements.China National Heavy Machinery Research Institute has developed a ten roll quick open straightener based on six roll quick open straightener,which improves the straightening accuracy of steel pipes in heat treatment line.Ten roll straightener has five upper sliding beams,and the adjustment process of roller gap is more complex than that of six roll straightener.Adjustment schemes is different with different adjustment parameters.In this paper,according to the mechanical structure of straightening machine,a single straightening roller gap adjustment system is established,and on this basis,the upper roller gap adjustment system of main machine is established.
