چکیده:

In this paper, the stress and load relations in backward rod extrusion of lead have been obtained by the slab method for curved die profile. By the use of a developed computer program, the optimum die profile has been obtained on the basis of minimization of stress and load in die-workpiece contact surface. By using the FEM software, ABAQUS, the optimum die angle for the conical die is also determined. Then, the finite-element and experimental load-displacement curves have been determined. It is illustrated that the extrusion load for optimum curved die is reduced by 11%, compared to that in the optimum conical die.
