Projeto de um sistema integrado de multiplicação de pressão hidráulica

Abstract

The study and application of hydraulics in manufacturing processes has gained a lot of space in recent decades, mainly for its reliability and ease of automating processes. In machining fixture devices applications are mostly the generation of mechanical force for clamping parts during manufacturing. Although there are pressure intensifiers on the market, their placement in fixture devices generates a high increase in costs, mainly due to the placement of more valves to control the operation of the intensifier, making its use unfeasible. In this academic work the project and prototype of a pressure multiplier was developed, with the necessary valves integrated for its installation in a machining fixture device. Through research on the functioning of components available on the market and conditions of use for the intensifier, the basic operating assumptions of the system were identified, as well as the minimum necessary multiplication values. The project was then modeled and detailed using CAD software and finally manufactured and assembled, using resources provided by a metallurgical company. Finally, the prototype was tested using the most used pressures for this market segment, where it was observed that its operation occurred as expected, although pressure losses were identified during the tests of the multiplier, resulting in an inability to achieve the pressure indicated in the design, requiring the readjustment of the project.
