Roteiro de dimensionamento de uma unidade hidráulica para funcionamento de uma prensa em trabalhos de forjamento

Abstract

This work presented a methodological script for the design of hydraulic systems for presses. Using as a practical example the requirements of an 80-ton press. Therefore, the stages of design in machines and the operation of all the parts that make up a hydraulic unit are studied. These parts are divided into four parts: Primary conversion system, distribution and control system, transmission system and energy application systems. The cylinder, the hydraulic pump, the electric motor, the directional valves, check valves, flow and pressure regulators, the filters present in the suction, pressure and return line, pipes for the three lines, as well as hoses, finally the reservoir and manifold block, will be dimensioned. As a result, the roadmap validates the methodology through a practical example, demonstrating that the sequence of calculations leads to a coherent and functional design, capable of achieving the strength and performance requirements.
