Full Article:

The results of theoretical analysis of metal forming process of hub forging from AZ80 magnesium alloy are presented in this paper. Calculations were made with the application of commercial software based on finite element method. Simulations were conducted for two technologies of forging: on a die hammer and on a hydraulic press. Kinematics of material flow, strains, temperature and fracture criterion according to Cockroft-Latham were analyzed. Forging force in the case of press usage and impact energy in the case of hammer usage were calculated as well. On the basis of the obtained results, the analysis of limiting phenomena, which could appear during the process, was made. These phenomena include: possibility of overlapping presence, not filling of die impression, overheating of material and cracks. On the basis of calculations of forces and energy necessary for forming, required parameters of forging machines were chosen. Theoretical verification of hub part forging technology allowed to state that it is possible to obtain final product of assumed quality. The results of calculations provided the basis for planning of experimental tests in industrial conditions.
