摘要: 针对目前拉弯矫直过程缺少完整的数学求解模型的问题,根据矫直带材在拉弯过程中,中性层偏移量及延伸率的计算模型,给出了拉弯矫直张力、矫直力和延伸率的计算方法。通过计算与工业试验,分析了拉弯矫直机矫直规程对残余延伸率的影响,并验证了计算模型的精确性。

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.

Key words: stretch-bend straightening, tension, elongation, calculation model, industrial test
