Diseño y Construcción de un Banco de Pruebas para el Estudio del Proceso de Deformación Incremental en Chapas de Aluminio AA 1200 H14.

Abstract

This work describes the study of the incremental deformation in aluminum sheets AA 1200 H14 for which the necessary tools were designed and built, and with this to be able to implement a new process of forming in metal sheets to the mechanical forming laboratory of the FIM. On the other hand, it seeks to transfer innovative concepts that help to improve the conventional processes for sheet deformation currently available in the country's productive sector. In order to carry out this work, the variables of the process and its parameters of importance were determined, the possible ways of deformation in metal sheets were studied, with this the simulation and experimentation of the process was defined. Several experimental tests were carried out on 1 mm thick aluminum sheets using tools of different diameter, the behavior of the loads required for this process was obtained by varying the diameters and angular speeds of the tools, surface finishes, and flat deformation was determined in This process. It was found that the surface finish and the formability improve as the tool diameter increases to a certain limit, and the rotation of the tool decreases the load required in the process.
