Computer Simulation and Study of the New Forging Technology of Billets in a Step-Wedge Dies

Abstract:

The paper presents the results of a computer simulation of the drawing process in the step-wedge dies of two configurations: with wedge-shaped protrusions in the first and second sections of the top and bottom dies, and with a wedge-shaped protrusion in the first and second sections of the top die and wedge-shaped cavity in the first and second sections of the bottom die. A comparative analysis of the stress-strain state and energy-power parameters is carried out. Based on the analysis conclusions about the feasibility of choosing a specific configuration of step-wedge dies depending on the set aim were made.
