Process Parameter Optimization on Pneumatic Bulging for Abnormity Thin-Wall Pot
To enhance the forming quality of pneumatic bulging for abnormity thin-wall pot and reduce such forming defects as severe wall thickness reduction and fold breaks. Based on numerical simulation, this article analyzes the impact of the friction factor, die radius of curvature, pot wall thickness and load pressure on the wall thickness reduction rate, maximum stress and axial contraction. The experiment result is consistent with the numerical simulation. The research results have greater practical value to process optimization and process control.
