Abstract
In this paper, based on elastic-plastic hydrodynamic lubrication theory and metal-forming mechanism, a model of hydrodynamic lubrication during cold extrusion is established. The frictional boundary condition during rigid-plastic finite element simulation of cold extrusion is dealt with using the proposed model. In addition, the distribution of strain in the billet during cold extrusion is analyzed by FEM. The numerical result is discussed and compared with the experimental result.
