Abstract

The design of die block for drawing with differential radial backup was developed. The magnitude of backup changes proportionally to load of drawing. The analysis of drawing with differential radial backup of hollow workpieces made of low-carbon steel carried out by finite element method. The influence of backup’s magnitude on load modes of drawing and work of deformation were determined. The final geometry of detail, mode of deformation, strengthening and ratio of metal plasticity resource after deformation were determined. The values of reduction of radial tensile stresses at the flange of the workpiece and axial tensile stresses in the wall of the detail were obtained. This achievement provides increasing the height of the final detail in one step.
