Abstract:The straightening roll is tools of cross-roll straightening machine used for tube straightening and roll profile of it is special curved surface, the design of roll profile decides the performance of straightening. The working principle of steel tube cross-roll straightening machine and the theoretical requirement of roll profile were introduced. Selected the object for study and built the coordinate system, based on the analysis of geometry character for spatial contacting curve between roll profile and standard tube, the character of roll curved profile was described through equations of spatial contacting curve, roll curved profile and roll profile generating curve deduced by a set of mathematical routes. The theoretical verification of different algorithms was realized by unifying of spatial contacting curve equations deduced by this method with the equations deduced by conjugate surface theory. The data of roll profile generating curve for one straightening machine size was calculated by the deduced equations, then the data processing method and the effect were introduced. The method above was applied to roll profile design for 3 straightening machines in a new plant project, the site testing showed that the roll profile contacted with the standard tube fully under the basic condition and the tubes were straightened well in production.
