ABSTRACT:Straightening technology as a finishing technology, occupies an important position in the history of industrial development. With the straightening theory continues to mature, straightening precision and efficiency has been greatly improved. Straightening machine used is called straightening machine, including pressure straightening machine, parallel roller straightening machine, oblique roll straightening machines, rotary trans curved straightening machine, tensile and bending straightener. Currently these types of straightening machine design and manufacturing are more mature in many industries has been widely used, especially in a straight swap accuracy and efficiency requirements are very high in iron and steel industry, straightening machine updates and more rapid development, Straightening theory in promoting the improvement and advancement has played a very big role.

　　　Rotating hub oblique roll straightening machine for straight tone wood, its simple structure, convenient operation, high precision straightening. This paper studies the small-diameter steel straightening machine design, the use of straightening theoretical empirical formula based on the design isometric hyperbolic roll and straightening designed under the guidance of theory straightening machine structure calculation is relatively simple, mature technology and high, especially for small-diameter construction site bar straightening.
