一、前言近年来在国内的一些杂志上先后发表了不少有关管(棒)材矫直机辊型曲线的分析文章。这些文章均力图用简捷明瞭的方法求解全接触辊型曲线,借以改善矫直效果。到目前为止,全接触辊型的求解方法已不下好几种。这些方法大多从垂直辊轴的截面投影上去观察管(棒)材与轧辊的相切关系,进而求出该截面处满足相切条件的轧辊半径。此时若以截面位置为参量,则可沿轧辊长度方向求出一系列的轧辊半径值,由这些半径值所确定的辊型曲线即为全接触辊型。作者把这一类 First, the foreword In recent years, some domestic magazines have published a lot of tube (rod) material leveler roller curve analysis article. Each of these articles seeks to provide a straightforward and straightforward solution to the full contact roller profile to improve the straightening effect. So far, the full contact roller type solution has been better than several. Most of these methods observe the relationship between the tube (rod) material and the roll from the projection of the cross section of the vertical roller shaft, and then find the radius of the roll satisfying the tangent condition at the cross section. In this case, if the cross-sectional position is used as a parameter, a series of roll radius values ​​along the length of the roll can be obtained. The roll profile determined by these radius values ​​is the full contact roll type. The author of this category
