Estudio del proceso de conformado en lámina metálica de un soporte posterior cubierta de cocina Domestica Mediante modelado de elementos finitos

Abstract

In this document, the evaluation of the mechanical forming process of the rear support of the domestic kitchen countertop, manufactured with 1.4 mm thick galvanized sheet, is addressed using the finite element approach. The overall goal is to thoroughly examine this process, focusing on the galvanized sheet selected. Four essential components are structured: first, establish the mechanical properties of the galvanized sheet through bibliographic research and experimentation; second, identify the key parameters that influence the mechanical forming process for the galvanized sheet. For this study, the pressure of the presser plate, the thickness of the material, and the radii of the formed element were considered. Third, formability limits based on the current design of the galvanized sheet element will be determined through finite element simulations, offering a precise view of its behavior under different forming conditions. Finally, the economic viability of the rear support forming process is evaluated using financial indicators to provide a comprehensive analysis of the economic efficiency of the process. This multidimensional approach allows for a complete understanding of the mechanical forming process and its impact both in terms of mechanical properties and economic viability. A process utilization of 68.31 % and a material utilization of 62.68 % are obtained as relevant data.
