- Abstract
Reasonably determination of the rolling temperature of the cross wedge rolling (CWR) is the key to o btain the qualified surface of the aluminum alloy shaft parts. In this paper, the 6 082 aluminum alloy shaft parts with different section shrinkage rate between 43,75 % and 64 % are taken as examples. The thermal-deformation coupling finite element model (FEM) is established to analyze the effect of the process parameters on the temperature field. The influence law of the temperature field on the surface quality in CWR process is obtained and verified by experiment. The results provide theoretical and experimental basis for temperature selection and surface quality improvement.
