Options of crimping in a container and matrices of a special profile of axysymmetric hollow billets made of C60 steel

Mathematical models were created using the finite element method and research was carried out on options for hot, semi-hot cold crimping in a container matrix of special profile axisymmetric hollow blanks made high-carbon steel with variable wall thickness along height. A plastic model metal is used. Before hot crimping, part workpiece heated at height to be deformed. The shape dimensions initial blank determined by calculation, which ensured required product. use deforming surface ring protrusions it possible obtain product one pass considered due reduction influence frictional forces during molding. rate deformation maintain mode crimping. dependence axial force tool movement punch distribution specific contacting surfaces established. pressing leads an increase accuracy product, decrease energy consumption consumption. final stress-strained state metal, are determined. Based intensity, evaluation working structure out, yield point after predicted. On basis simulation data, design general appearance die equipment developed.
