The paper’s authors researched the defects correction for RSt 34-2 (1.0034) steel wire, obtained as result of its overheating at 1140...1160 °C. Instead re-heat treatment method, proposed five cold drawing, annealing and combination schedules, which ensure increase in strength to DIN EN ISO 6892-1-2020 requirements. experiments were performed on 4 mm diameter wire with increased grain size (up ...

The cup drawing is a basic deep drawing process. Thus, understanding the mechanics ofthe cup drawing process helps in determining the general parameters that affect the deep drawingprocess. There are mainly two methods of analysis; experimental and analytical/numerical.Experimental analysis can be useful in analyzing the process to determine the process parameters thatproduce a defect free prod...
