§2—3递减反弯矫直 1.矫直原理为了克服普通压力矫直机的效率低,质量差的缺点,适应大量连续生产的需要,必须设法研制高速连续工作的矫直机。人们从实践中受到启发:金属轧材在明显的塑性弯曲情况下,卸载后各处的弹复能力几乎是相同的。因此不管轧材各处的原始曲率如何不一致,在较大弯
§2-3 Decreasing Recoil Straightening 1. Straightening Principles In order to overcome the shortcomings of low efficiency and poor quality of ordinary pressure straightening machines and to meet the needs of a large number of continuous production, it is necessary to try to develop a straightening machine which can work continuously at high speed. People are inspired by the practice: the metal rolling material in the obvious plastic bending case, after unloading the resilience everywhere is almost the same. So no matter how the original curvature of the rolling material is inconsistent, in the larger bend
