Possibility of making details with smooth wall after burring because of correction of punch’s shape was shown

Abstract

The analysis of burring of hollow perform obtained by drawing of blanks made of low-carbon steel was carried out by finite element method. The influence of cylindrical, conical and spherical punches on the load modes of burring and work of deformation was determined. The final geometry of detail, mode of deformation, strengthening and ratio of metal plasticity resource after deformation were determined. Possibility of making details with smooth wall after burring because of correction of punch’s shape was shown. By results of calculation the manufacturing method of hollow products from low-carbon steel is developed. The manufacturing method consists of operations of a drawing, punching for burring and burring.
