Obtaining the necessary data to proceed with the selection of materials, these being previously investigated and generating again a selection matrix which allows us to compare their different characteristics, costs and also determine the material to be used. Subsequently, the manufacturing process begins where the different materials will be subjected to their respective processes starting with cutting, followed by turning the axes and screws, drilling, welding and threading, as the design requires and specifies; likewise with starting the assembly of the prototype and the performance of tests with their respective correction. The prototype work area consists of a table with space for wiring with dimensions of 0.50*0.90m where on its surface it has the central axis of operation, the circular base attached to the central axis which will receive the empty glasses and by its rotation, it will stop in the filling, capping, threading areas and its respective exit to a conveyor belt which will take the full glasses to the next station. As an auxiliary structure, it has supports around the base which support worm screws that move the capping and threading systems. In addition to the above, the creation of detailed documentation is required to complement and support the behavior of the prototype materials, construction plans, selection matrices and prototype description.Ítem Diseñó y puesta en práctica de procedimiento de instalación y revisión periódica de puntos de anclaje fijos para el trabajo en alturas, bajo la resolución 4272 del 2021 emitida por el Ministerio de trabajo(Universidad Distrital Francisco José de Caldas) Cortes Ortiz , Miguel Ángel; González Colmenares , MauricioThis manual provides a detailed and complete guide for the correct installation of fixed anchor points, designed to provide a safe and reliable work environment at heights.

In many of these spaces, the equipment suffers damage or breakdowns, and in the worst cases, they are stored away and replaced. As a result, the opportunity arises to recover one of these machines. This project aims to carry out the restoration and overhaul maintenance on one of these pieces of equipment (Infersan Revolver Lathe), with the goal of putting it back into operation. To achieve this, a preliminary analysis of the asset and its components will be conducted at the beginning of the process. At the end, a detailed record will be kept, documenting both the result obtained and the restoration and manufacturing of missing or damaged parts, as well as the assembly phase of each component. The outcome will be the optimal functioning of the Revolver Lathe, making it suitable for the production of mechanical parts through the application of semi-automatic processes. Additionally, it will become an extra machine available to both students and other staff at the university who have access to these tools.Ítem Caracterización y clasificación del hierro gris producido por la empresa Industrias Murillo SAS bajo la norma ASTM A48Marin Henao, Wendy Natalia; Torres Corredor, Samuel; Muñoz Bello, Nicolas GabrielIn Colombia almost all sectors of the industry go through the same problem, the poor implementation of technology in the production and control processes, which makes the national industry not very competent at the time of supplying the demand of the national and international market. This is why companies such as Industrias Murillo Rodríguez SAS need to technify their processes and classify their products and services according to national and international standards. In the realization of this project, the characterization of the gray iron cast iron produced in the above mentioned company was carried out under the ASTM A48 standard, additionally the microstructure of the material was analyzed under the ASTM A247 standard, its hardness following the ASTM E18 standard and its chemical composition by means of the chill method governed by the ASTM A357 standard.Ítem Apoyo en la organización y sistematización del plan de mantenimiento para las maquinas en el área de producción de la empresa Proquinal S.A.S.Guerrero Rivera, Erick Jusseph; Alvarado Moreno, AlexanderThe maintenance plan with lubrication routes developed in this The internship modality was carried out in a general way, based on the study of failures, strategies, planning for the organization of maintenance, as well as such as the design of formats and construction of these. where they intervene professionals, technicians who contribute their knowledge, according to their training, to be able to carry out this project.

Initial calculations were performed to define parameters such as the thickness of the rings for the location of the joint, the working pressure and the projected diameter of the tank; some theoretical stresses present in the tank were calculated. Then, the two welded joints were modeled using the SolidWorks CAD software, made in order to have a conformity and non-conformity according to the international API 650 standard. These models were exported to the ANSYS software in its Workbench section. In the first stage of the simulation, the transient thermal process was executed, a stage in which the welding was replicated in its SMAW method and where the thermal behavior of the joints was obtained in an interval of 120 seconds. The second stage of the simulation consisted of the structural section, where conditions such as hydrostatic pressure, the force of the tank weight, among others, were considered. With this, deformation and stress results were obtained, influenced by the previous thermal development in the model. With the results of the simulation, several detail nodes were set at certain distances from the weld bead, at these points the thermal behavior was obtained and, based on the CCT diagram of the material, the cooling rates of each point were determined. Once the velocities were obtained, the phases present in the material and their respective percentage at each point in both the rejection and acceptance joints were calculated. In the structural part, points in the porosities of both joints were also determined, and the stresses and strains present in these nodes were analyzed. Finally, the thermal and structural results in the nodes of both joints were compared to evaluate which of the two models presents a better performance and efficiency under the conditions established for the storage tank. Once the development was completed, the respective analysis was carried out, in which it was emphasized that the value of the stresses and strains is influenced by the amount of porosities and their diameter, as well as the possible problems that this may mean over time for the possible application in reality.Ítem Diseño y análisis para la construcción de una bancada de una maquina de precisiónBernal Amortegui, Miguel Angel; Castro Pasives, Sebastian; Guasca Gonzalez, Andrés GuillermoThe project focused on designing a machine bench for a precision machine with the objective of improving precision at microscale.

During the development of this project, the feasibility for the survival of methanogenic organisms in the biomass, which can produce methane gas by means of an anaerobic digestion process, was found. As a biodigestion system it is recommended to use a Batch type system, this is presented as the best option, due to the frequency of biomass generation, which is generated once a month, in a period of 2 to 3 days, it is also presented as a system in which dry organic matter can be added, giving the possibility of having a greater control of the acidic environment that can be produced inside the container. For this type of biomass, an approximate production of 160 𝑁𝑚3 of biogas is calculated in an estimated time of 100 days, with a calculated methane content of 120 𝑁𝑚3. By improving the pigmentation process of the skins, there is an internal rate of return of 100% of the investment.Ítem Análisis del comportamiento a flexotracción de adoquines elaborados a partir de plástico reciclado; con combinación de polietileno de alta densidad (HLPE), polietileno de baja densidad (LDPE) y polipropileno (PP)Giraldo Toro, Alfonso; Hurtado Cortés, Luini Leonardo; Nieves Pimiento, Nayive; 0000-0002-1675-9471; Hurtado Cortés, Luini Leonardo [0000-0002-1675-9471]The project is carried out the analysis of the flexural shrinkage behavior of pavers made from recycled plastic; with combination of high density polyethylene (HLPE), low density polyethylene (LDPE) and polypropylene (PP)
