Diseño y construcción de una prensa y molde para compactar polvo metálico para el laboratorio de materiales de la Carrera de Ingeniería Mecánica

Abstract

This project aims to develop a methodology for the design and construction of hydraulic presses with powder metallurgy applications, and also allows people interested in the subject to determine the most significant design theories for this case. For this, the manufacturing process of the metal powder compacting elements was carried out, according to ASTM B 925-03, which allows the preparation and production of specimens for P / M powder metallurgical tests, and for each mechanical element of the hydraulic press, considering the design theories learned in the course of the career, put into practice in this thesis topic. For the manufacture of powder metallurgical specimens, a series of samples were made and their geometry was evaluated to determine their validity by means of a 6 ”/ 150 mm insize brand king foot calibrator that provides a minimum percentage of error as established by ASTM B 925 -03. After having performed the analysis of the dimensions of specimens obtained, it was evidenced that the dimensions of these tests were maintained within the tolerance range established by ASTM B 925-03. With this, it was possible to verify the optimal operation of the machine and that our project met the objectives established for the different test specimens.
