Resumen
El objetivo principal de este trabajo es estudiar la configuración geométrica optimizada para llevar a cabo el embutido mecánico de placas. Para ello, se ha realizado un análisis comparativo de algunas configuraciones geométricas y cinemáticas adecuadas del material situado en la zona de deformación. En concreto, se han elegido varios modelos de zona rígida triangular, para cada uno de ellos se ha calculado la energía global implicada en el proceso y se ha realizado una estimación de sus diferentes componentes. El cálculo de la energía se ha realizado aplicando el Teorema de la Cota Superior en condiciones de deformación plana y fricción parcial. Además, se ha establecido el rango de utilización de las configuraciones seleccionadas.
To study the optimised geometrical configuration to carry out mechanical drawing of plates is the main objective of this paper. To accomplish this objective, a comparative analysis of some suitable geometrical and kinematic configurations of the material located in the deformation zone has been made. Concretely, several triangular rigid zone models have been chosen, for each one, the overall energy involved in the process have been calculated and an estimation of its different components has been made. The calculation of the energy has been achieved applying the Upper Bound Theorem under plane strain and partial friction conditions. In addition, the range of use for the selected configurations has been established.
