Abstract

The backward extrusion process for the vacuum cup inner cylinder of AZ31 magnesium alloy was simulated by DEFORM-3D finite element software.The effects of the temperature and the extrusion speed on the equivalent stress and extrusion force were analyzed.The results show that the maximum equivalent stress was mainly concentrated around the punch round.With temperature increasing,the maximum extrusion force decreases.The greater the extrussion speed,the larger the maximum extrusion force.
