Projeto e análise estrutural de uma prensa de parafuso

Abstract

In an automobile assembly line it is usual to use screw presses to join mechanical assemblies in which the components are fixed to each other through interference. In order to produce this kind of ajust, the parts are slowly force one against the other by a intense force aplied by the mechanical press. Therefore, it is necessary that the project of a mechanical press be capable of foresee with some precision the stress field during the press process. On this scenario this work intend to, trough analitical methods from techinical literature and also trough the finite element method enviroment of Inventor, perform the project and sctructural analysis of a screw press. In the beginning, some concepts about project methodology and the finite element method will be presented. After this stage, the methodology development wil be done in first place with the dimensioning of the critical components and just after that it will folow a strutural analysis of the entire press trough the finite element method. In the end, after some considerations about the results and the individual safety factors, will be added to this work all the technical drawings such as exploded view, assemblie drawing and parts drawing.
