Wall Thickness Uniformity in ISF of Hydraulic Support: System Design, Finite Element Analysis and Experimental Verification

Uniform wall thickness plays an essential role in avoiding forming failure incremental sheet forming. However, it is challenging to promote the uniform distribution of single-pass high angle and complex three-dimensional thin-walled parts using flexible dieless technology. In this article, based on hydraulic support single-point technology, finite element software used simulate analyze influence different pressure critical truncated pyramid parts. The results show that can effectively improve uniformity angle. addition, a increment experiment system designed, corresponding obtained. experimental are consistent with simulation results. Therefore, article provides guidance for manufacturing angles
