| Sumario: | An approach for the evaluation of the mechanical performance of the bar and roller system of a steel bar bending machine is presented. It can be applied for design or retrofit purposes, with emphasis on the improvement of existent systems. The approach is illustrated for the case of a machine that has continuously lost its functionality due to fracture, surface fatigue, high power consumption and shape dimensions outside of specifications. The elastoplastic behavior of the bar is analyzed to determine the power consumption during the bending process. Moreover, the definition of the main design factors that govern the failure mechanisms in these components is carried out. A system of constraining equations is obtained, which is solved for a target function for the production capacity. Lastly, the enhanced redesign of the machine with new functional characteristics is presented |
