| Abstract: | At present, there was a lack of complete mathematical model in process of stretch-bend straightening. According to the calculation models of the neutral layer offset and the elongation of the strip in the process of stretch-bend straightening, the calculating methods of the tension, straightening force and elongation were given. Through calculations and industrial tests, the effects of the straightening procedure on the residual elongation were analyzed, and the accuracy of the models was verified. |
