Dimensionamento de uma unidade de potência hidraulica para uma bancada de conformação mecânica

Abstract

The equipment used in industry, in particular the hydraulic units, allow the execution of processes that require the application of great efforts allied to a relatively small work area. In order for these equipment’s to work correctly it is essential to have them correctly sized. The present paper deals to scale a hydraulic power unit for carrying out mechanical forming processes such as bending and stamping, whose main problem is the high cost of the machine components. This project was undertaken in order to obtain a hydraulic system ideal for a given situation and save when choosing the pieces. To achieve these expectations methodological procedures were adopted which include the analysis of the appropriate theoretical basis; knowledge of equations necessary for the development of the sizing of the actuators, pump, pipes and the tank; cargo loss analysis in the valves and in the main pressure line, determination of shear force besides the definition of the ideal components through the available manufacturers catalogs. From this study it was possible to determine the best way to scale a hydraulic power unit for the above processes, and ensure economy and system performance.
