PARRA-MONTERO, Claudia Ibeth; SIMEON-MONET, Rolando Esteban  e  PINO-TARRAGO, Julio Cesar. Optimal design of linear aluminum alloy extrusion diez. Ingeniería Mecánica [online]. 2021, vol.24, n.1, pp.63-69.  Epub 07-Jun-2021. ISSN 1815-5944.

The rapid wear of the aluminum extrusion dies, given the intense working conditions, means that the profiles obtained do not guarantee the admissible tolerances for all the necessary production. Hence, the aim of this research is to optimize the design of linear dies for the extrusion of aluminum alloy profiles, based on the geometry and dimensions required to be obtained, with a view to increasing the useful life of these costly tools. To this end, the calculation process is automated and variables such as: material, extrusion capacity according to the existing machines and exit channels are incorporated. These variables are used to determine the required pressure, die thicknesses and entry angles. All these elements are linked in a single-objective optimization model developed in MATLAB, where, from the possible solutions obtained, the variant to be designed is chosen according to the criteria desired by the designer and is automatically linked to the modelling with a professional CAD package, which allows the 3D design of each component of the die to be obtained, so that the required dimensional requirements are met, focused on increasing the durability of the tool.
