Diseño validado mediante software de una máquina para la elaboración de cuerdas a partir de botellas PET

Abstract

The objective of this technical project was to design and validate through software a semi- automatic machine for the elaboration of ropes from pet plastic bottles, through the conceptual design and functional structure to determine the needs and requirements of the prototype, in addition to the weighting method to quantitatively demonstrate the best alternative of the design presented in the document. The axis was designed, and the safety coefficient was obtained in addition to the fatigue analysis using SolidWorks with the consideration of infinite life, also SAP2000 was used for the resistance analysis of the support structure using the AISC 360 Standard following technical parameters that require a job titration, also doing a modal and frequency analysis determining the ability to withstand dynamic loads with minimal deformation. The design and simulation of the blade was carried out using SolidWorks and a comparison was made between AISI 1020 cold-rolled and AISI 4340 annealed steels to determine the one that provides the best conditions at the time of cutting the bottle. It was shown that the different design, simulation, and strength analysis computer programs are necessary and useful tools that not only allow a clear idea of the final product, but also significantly reduce design, execution, testing and change times that could be made. present. A complete analysis of the blade with stainless steel is recommended, which can determine its influence on the homogeneity and the production of lint in the rope, and by carrying out an analysis of the thermal treatments of the ropes obtained, it is possible to have a broad panorama of the applications for the product of this technical work.
