Experimental Investigations and Analysis of Springback Based on Multi-Angle Panel Draw-Bending
A real time strain measuring device has been designed in allusion to multi-angle influence on springback in shaped parts. The strain has been studied at the shaping of part with different bend angles’ numbers. The multi-angle draw-bending forming and springback mechanism have been observed by metallurgical structure searching.
