Diseño y construcción de un molde para compactación de pulvimetalurgia para elaboración de probetas cilíndricas

Abstract

The present project is about the design and construction of a mold for compaction of powder metallurgy, for which were taken into account two fundamental parameters, that the specimens obtained in the mold are easy to extract so the mold is dismantleable and how to obtain the best compaction of metallic powders. Therefore, for the mold design and the verification of the strength of the materials, was used a software, in which were obtained tensions, deformations, displacements and safety factors. Two alternatives were proposed taking into account the mentioned parameters, a mold was made for longitudinal compaction and another one for transverse compaction by blows. For the punches, was also performed a mathematical analysis, as well as calculations to determine quantities of metallic powder required to obtain tensile test specimens and their respective compaction forces for the three materials tested, aluminum, bronze and steel. In the compaction of metallic powders, was used the compression machine for concrete, in which were obtained three longitudinal compaction probes and three transverse compaction probes and thus obtaining the best mold design.
