Analysis of critical components of a hydraulic folder with fi nite elements Análisis de componentes críticos de una plegadora hidráulica con elementos finitos

Abstract

This project was developed in May 2021, at the Salesian Polytechnic University in CUENCA-ECUADOR, assessment of the critical components of a hydraulic folder to maximum force compression load that materials must tolerate, based on mathematical calculations and static analysis of finite elements using the SolidWorks tool in commercial steels, ASTM A36, SAE 1020 and SAE 1045. Subsequently, the components to be analyzed and the loads they are exposed to are determined, achieving as the optimum width regarding the safety factor for the construction, presenting minor deformations in the parameters of maximum compressive stress, bending, and buckling. Results reveal that the minimum deformation, according to parameters mentioned before, is 0.19 mm for the punch and 0.04 mm for the bending die, generated in SAE 1045 steel. Considering this condition, this material is chosen for the construction of the different elements used and the deformations are verified under the same initial conditions. Lastly, with the results attained, it is demonstrated that the geometry and dimensions of the components will ensure that they will operate efficiently and avoid mechanical failures during the dynamic operation of the equipment.
