摘要
根据凸筋拉缩变形的力学条件,研究了工艺因素对凸筋拉缩的影响规律。采用多元非线性曲线拟合的方法,建立了凸筋拉缩的数学模型,可用于凸筋拉缩量的预测及管坯规格的选择。
In this paper, stress conditions of rib reduction are presented and the influence of the process conditions on rib reduction is investigated. By means of multiple non-linear curve fitting method, was established the mathematic model of rib reduction, which can be applied to production of rib reduction and size selection of cold-drawing materials.
