Исследование силового режима процесса высадки внутреннего фланца из трубной заготовки методом верхней оценки

Abstract

A study of the power mode of the process by draught the inner flange of the upper bound of the tubular workpiece using a mandrel with a sharp edge and the radiused transition. Optimal value of the parameter i that characterizes the position of the deformation zone is 0.7. The effect of friction, flange height and relative radius of curvature at the transition edge mandrel reduced pressure deformation
