Sažetak
The paper presents experimental results of investigations of hydromechanical bulge forming of copper axisymmetric components whose relative wall thickness was s0/D = 0,045. The deformation ratio of material in the paper was defined as relative upsetting ratio Dl/l0 (where Dl – the punch displacement, l0 – initial length of tube). The investigations produced a liquid pressure and a force profile in hydromechanical bulge forming of copper axisymmetric components with different relative ratios Dl/l0 = 0,054 ÷ 0,109. The research aimed to determine the impact of upsetting ratio on mechanical properties for hydromechanically bulged axisymmetric components. The tensile strength Rm increased and the percentage reduction of area Z decreased as the upsetting ratio Dl/l0 increased.
