    Repotenciación del sistema de refrigeración del horno de inducción utilizado para el proceso de fundición en los laboratorios de la FICM
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-08) Campaña Salas, José Javier; Guaita Morales, Jhoel Andrés; Paredes Salinas, Juan Gilberto
    In the laboratories of the faculty there is a broken induction furnace, which needs improvements in its cooling system to be operational and contribute in the area of manufacturing processes. In this research, the cooling system of the induction furnace for low-capacity aluminum smelting was upgraded to ensure efficiency and improve the durability of the equipment in order to ensure an efficient smelting process. The parameters evaluated included volumetric flow, temperature and water pressure, even though the furnace had a minimum capacity for aluminum alloys and operated at 7 kW power with specific voltages. Calculations were detailed: chiller selection, circulation pump specifications, water storage tank size, including infrastructure needs for furnace portability and water recirculation system, plans and a comprehensive budgeting scheme were developed as part of this integrated approach. As a result there was the improvement of the cooling system through water recirculation, eliminating direct waste in the drains and improving the casting processes in the laboratories of FICM, this initiative takes into account that the induction furnace significantly exceeds the heat production time compared to the times of a gas burner that takes 240 minutes, while the induction furnace 5 minutes, reaching thermal loads of 139348.62 J with a volumetric flow of 2,735 L/min.

    This Technical Titling Project focuses on the design, construction and operation testing of an attritor-type ball mill for obtaining powders and alloys from metal chips, acquiring information about the process of powder metallurgy, data and characteristics of the material and using, selection weights of alternatives, criteria such as design and calculation corresponding to the most relevant parts of the milling. As a basis is the analysis of the grinding parameters with the attritor mill should be recorded, such as the turning speed, contamination of the powders due to the material, temperature control and grinding time. Continuing with the selection and weighting of the operating systems in the machine being valued according to weighting criteria such as reliability, maintainability, assembly and price of each of the alternatives to subsequently be calculated valued with its reliability factor. Finally, we proceed to the construction and assemble of parts and elements of the machine being these built and others acquired. One of the most relevant the frequency inverter because it regulates the turning speed and prevents the engine from suffering damage in case of jams and then goes through the operating tests, obtaining the expected results in the mechanical grinding.

    Diseño y construcción de un molde de inyección de carcasas de protectores auditivos de la empresa Halley Corporación
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2018) Mejía Bonilla, Marco Fernando; Carrillo Rosero, Carlos Mauricio
    Injection molding is going through for a technological transformation with trends such as: intelligent machines that are solutions that can be optimized themselves, the automation can now control virtually any industrial process, the sensor that can detect a wide range of magnitudes and the additive manufacturing that allows small productions of pieces, the elaboration of pieces of high complexity at low costs, the construction of molds, among others. The national competition has forced the company Halley Corporation to supplement its safety kit with hearing protectors, the importance of this project is that a plastic injection mold was built, contributing to the exploitation of the industry. In the present work the piece was designed in a specialized software, injection mold components were designed, feed, ejection and refrigeration systems were designed using only written bibliographies, in addition the mold components were machined with calculations based on the tools of the company. The final product obtained ratifies that the design was correct , there were no disadvantages when trying the mold and to make the assembly with the rest of the elements that make up the safety kit.

    Diseño y construcción de un molde de inyección del arco almohadillado, de protectores auditivos para la empresa Halley Corporación”
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2017) Casañas Bonifaz, David Ignacio; Carrillo Rosero, Carlos Mauricio
    The object of the present work is satisfy the necessity of the company Halley Corporation, with the end of do the arc pad in series in the same time with certain dimensions, for this reason the author of the work have requirements of the company for elaborate the mold, like the material that will be used for the building, and the plastic that will be used for inject the object that need the company. For this reason, the project was started with the modeling of the arc pad in a specialized software, after that we got the nucleus and cavity of the object to inject. Then with the help of the software we analyze the demoulding angles and the dimensions that need the arc pad. For other part, the calculations were obtained in based of requirements of the company like the material that will be injected, in this case the material is ABS, and the material that will used for the building of the mold Among the calculations that were obtained are the feeding, refrigeration and expulsion systems for asegurate the correct operation of the mold. For finish the project we realized machining of the arc pad with a CNC milling machine, also it was built the different elements that make up the mold. The tests of the construction of the mold were realized with the help of an injecting machine, in this moment we look that the selection of the systems were correct, because the mold had an adequate efficiency in the injection process.

    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2015-07) Punina Banda, Segundo Javier; Hidalgo Velasteguí, Andrés Sebastián
    El presente trabajo de investigación se cumplió conforme a los requerimientos del Centro de Investigación y Desarrollo de la Fuerza Aérea Ecuatoriana, gracias a las diversas simulaciones ensayadas se determinaron para el compartimiento central del UAV una aplicación de 15 m/s, velocidad de aire que da un caudal suficiente para refrigerar por aire forzado a los elementos electrónicos como el Transmisor RF y Amplificador, manteniendo por debajo de 38°C, protegiendo a estos dispositivos que no cometan errores en el procesamiento de datos. De la misma forma con una velocidad de aire a partir de la velocidad crucero 28 m/s aplicado a las entradas de aire para la refrigeración del Motor Meggitt, es eficiente la disipación de calor, evitando que se transmita hacia los mamparos de aluminio y el fuselaje, manteniendo la temperatura del Mamparo Soporte y el Fuselaje por debajo de los 28°C, garantizado la integridad de los sensores sensibles que se encuentran dentro del compartimiento secundario, de igual forma los cilindros del Motor Meggitt se encuentran a 75°C, temperatura que es menor a lo especificado por el fabricante, impidiendo que la temperatura ascienda hasta niveles peligrosos que comprometan a este elemento importante del UAV-Gavilán. Para la elaboración del proyecto se realizó el diseño de un sistema de respaldo en tierra para la disipación de calor en el chequeo de pre-vuelo del vehículo aéreo no tripulado UAV – Gavilán, el sistema está diseñado en una bancada móvil para su fácil maniobrabilidad el equipo opera de forma automática y manual con la finalidad de mejorar la refrigeración del UAV-Gavilán en el chequeo de pre-vuelo, antes que efectúe las misiones designadas.
