RESUMO

The principal goal of this work is to develop a simulation method to predict the stress of steel cold extrusion in conical converging dies. To achieve this goal, the experiments were performed in a laboratory scale and a real scale. Through comparison of results from both scales, a correlation factors were defined. The experiments in the laboratory scale were performed using a universal testing machine and for the experiments in the real scale it was used a hydraulic cold forging press. It was also studied different methods to predict the extrusion stress to identify which of them would give a better approach to the readings from laboratory scale and real scale experiments
