摘要
通过绕弯试验和应变分析，研究了绕弯工艺的主要参数侧压Ｐ和相对弯曲半径Ｒ／Ｈ对曲率弹复ΔＲ的影响．得到了Ｐ和Ｒ／Ｈ对ΔＲ的影响规律及对毛坯变形区切向应变分布与变化的影响，为模具设计及修正以及工艺参数的调整提供了科学依据．
The effect of major parameters such as side pressure P, and relative bending radius R/H on curvature springback ΔR is studied, the law of interaction between P, R/H, ΔR and distribution and changing of tangential strain in deformation area is obtained, and thus, a scientific base is provided for design and modification of die and selection of technological parameters.
