Abstract
The cold drawn 42CrMo steel is taken as an example in this paper, based on the MARC three-dimensional elastoplastic finite element software, the stress-strain distribution in the deformation zone, metal flow and deformation law, friction coefficient, the relationship between die angle of drawing die and drawing deformation force during the drawing deformation of cold drawn 42CrMo section steel are calculated and analyzed. The process parameters are optimized by analysis and experiments.
