The paper presents a comparative numerical analysis of the tool wear in wire drawing process without and with backpull. The study was performed for the copper wire drawing cone by drawing die made of sintered carbide diameter of 3 mm mesh. A constant figure of 30% relative deformation ratio and the angle of pull of 9º was initially assumed. An axially symmetric numerical model of drawing process was...
W pracy przeprowadzono numeryczne modelowanie procesu ciągnienia drutu okrągłego z uwzględnieniem zużycia ciągadeł w zależności od ich kształtu. Do badań teoretycznych procesu ciągnienia zastosowano program komputerowy Forge2008Ž, który oparty jest na metodzie elementów skończonych i pozwala na termomechaniczną symulację procesów walcowania w trójosiowym stanie odkształcenia. Model zużycia stosowany...
