Simulação da matriz de estampagem profunda de um recipiente industrial utilizando aço EEP 19

Abstract

The forming process increases captivity in the production of metallic components when compared to other manufacturing processes, due to the high rate of production, small loss of material and low rate of rework. The vast majority of industries using the deep drawing process is based on the experience of professionals working in the preparation of equipment and those responsible for the manufacture of tools. Therefore, the trial and error method to obtain the finished product requires rework os the tool, impacting the component productivity. Given this, this work aimed to design the conformal matrix and simulate the deep drawing addressed using CAE Abaqus software, using as a concept a triple nonlinear analysis (geometry, contact and material). Through tension test by extensometer, the mechanical properties of the deep drawing material (EEP 19), and so, coming to it true plastic flow curve. Based on the design requirements and the definition of the preprocessing parameters, the process was simulated and later analyzed in different parts regions, in order to evaluate the material behavior during the whole forming process, having Von Mises stress and Maximum Principal stress to check for the possibility of fails (sic).
