摘　　要：矫直辊与管材是一对共轭曲面 ,矫直辊表面就是与圆环面密切接触的包络面 ,本文利用点在曲面上投影的原理 ,研究了管材在矫直辊之间为圆环面时 。The surface of the straightening roller and that of the pipe are conjugate.It is an enveloping surface that osculates with the donut.Based on the projection principle of points onto a curved surface,a manual method of drawing the straightening roller surface,if the pipe is in the shape of a donut between the straightening rollers,is introduced.
