Ротаційна витяжка осесиметричних деталей складної форми

Abstract

In the work are performed studies of metal blanks plasticity sheet depending on the mechanical properties of the workpiece material and load history, defined are geometric shape details and roller trajectory and conversions. To assess the value of ductility resource deformation criterion are used, which is based on the hypothesis of tensor nature of the accumulation of damage. The process of rotary drawing parts of complex shape is made by two stages.
