Abstract(s)
Uma prensa hidráulica é uma máquina com um circuito hidráulico caracterizado pela elevada força de compressão. É passível de transmitir esforços múltiplos, servido para esmagar, deformar ou elevar componentes pesados. O princípio da funcionamento da prensa hidráulica é baseado no princípio de Pascal que foi empregue pela industria para produzir máquinas capazes de utilizarem a pressão de um fluido para tarefas de compressão, utilizando o fluido como meio de transmissão de energia num sistema fechado para esmagar, endireitar, etc. A pressão é imposta pela máquina graças a um cilindro hidráulico que exerce esta força no sistema e provoca os movimentos do cilindro.
Projetar uma máquina de pressão hidráulica de cilindro de gás (13kg), objetivo deste trabalho, foi bastante interessante, para garantir uma boa abordagem, importantes aspetos foram considerados. Primeiro, fez-se uma revisão bibliográfica das diferentes prensas existentes, evidenciando seu modo de funcionamento, além de estudar a estrutura dos cilindros de gás e suas diferentes características. No projeto do sistema hidráulico e seus componentes foi utilizado o software de automação industrial da Festo. Também foi utilizado
o software SolidWorks para fazer o estudo de resistência dos materiais empregues e assim projetar a máquina de pressão,além disso, foi verificado a viabilidade económica do a máquina projetada; realizando um estudo financeiro para confirmar que a máquina benéfica para as indústrias de botijões de gás. Finalmente apresentaram-se conclusões deste estudo, apresentando propostas a desenvolver no futuro.
A hydraulic press is a machine with a hydraulic circuit, characterized by their very powerful compression force. It makes it possible to transmit a multiplied effort, serving to crush, deform an object or lift a heavy part, The hydraulic press is based on the principle of Pascal, then is mainly adopted in the industrial sector in order to ensure the execution of large pressure tasks and compression, their function is to use the pressure exerted on the fluids contained in its closed system to crush, straighten, etc. The pressure is made at the level of the plate (plateau) of the machine thanks to a hydraulic trigger which exerts this force on the system and causes the cylinder movements. The subject of designing a gas cylinder hydraulic pressure machine (13kg) is interesting and to ensure a good approach, important points must be followed. At first, making a bibliographical study of the different presses by giving their operating mode and their specifications, as well as to talking about the structure of the gas cylinders and their different characteristics, also going to the core of project is to design the hydraulic system components, then using the software of industrial automation FESTO to develop it, for this subject also it is necessary to make a study of materials resistance, then a very known software in the mechanical field it is the SOLIDWORKS to design the pressure machine, in addition it is essential to check whether this project is profitable by carrying out a financial study to find out the cost of this project and to confirm that it is beneficial to the gas canister industries, finally it must conclude this study by putting proposals to develop this machine in future.
