棒管材矫直机辊形曲面的设计研究

The design and study of roller curvature for the tube or bar straightener

二辊矫直机矫直棒、管材时,要求棒、管材与矫直辊呈全线接触,原有的辊形曲线方程计算方法繁而复杂,给出了一种管、棒材和矫直辊在全线接触情况下,二辊矫直机的凸辊辊形曲面的计算公式,结果符合矫直精度要求,计算简单方便,为二辊矫直机矫直辊设计提供了一种新方法。

The straightener roll should be contacted with the tube or bar in line ,when the two roll straightrner working. The originally calculation method of roll-shaped curve equation was extremely complex,so it presents a new method of bulgy roll-shape curvature in the condition of the tube or bar contacted with roller in line. By comparison,this calculation method is simple and easy,the more important aspect is that this method is guarantee the quality of product,accord with the required of accuracy. This method points out a new way in straightener roller design.
