本文应用能量法研究了钣料的极限旋薄角。由材料16AM和20鋼的实验数据证明理论分析与实验结果的吻合程度是满意的。 实验研究了滾轮圆角半径,润滑条件以及滚轮与心模之间的间隙对旋薄过程的影响。 在本文写作过程中得到了教学组刘渭贤,林兆荣,陈毓勋诸位老师的热忱帮助和指正,实验过程中得到范森和黄振康两位师付的大力支持,在此谨表谢意。 In this paper, the energy law was used to study the limit thinning angle of sheet metal. The experimental data of materials 16AM and 20 show that the agreement between theoretical analysis and experimental results is satisfactory. Experimental study of the wheel radius, lubrication conditions and the wheel and the gap between the heart mode on the thinning process. In the process of this writing, I got the help and correctness of the teachers from Weisen Wei, Lin Zhaorong and Chen Yuxun in the teaching team. Both of them were greatly supported by Fansen and Huang Zhenkang during the experiment.
