Rehabilitación de la prensa hidráulica para su implementación como máquina de prensado, conformado y montaje en el taller de máquinas herramientas de la Facultad de Mecánica

Abstract

The objective of this curricular integration project is to rehabilitate the hydraulic press in the machine tool workshop of the mechanics faculty since the equipment has not been used for some years. Later to implement the pressing, shaping and assembly processes, this due to its versatility of the equipment, since usually the hydraulic press was built to carry out a specific job. The identification of the main causes of damage was carried out with quality tools such as the Ishikawa and Pareto diagram, allowing the causes of damage to be classified graphically. A technical coding was carried out considering the location, area, and system. The current technical status of the hydraulic press was determined with 25.67% and identifying the type of maintenance service required as a general repair. Corrective maintenance was performed repairing the hydraulic cylinder, hydraulic pump, pipes, accessories, and frame. Topcoat and primer were applied to minimize corrosion; The safety signs and personal protective equipment that they must use for the workshop practices were installed. Preventive maintenance was implemented to extend the useful life and not have unplanned stoppages. The hydraulic press was validated by ANSYS applying two types of meshes for the convergence of values, which are the Jacobian Ratio and Skewness; giving a safety factor of 2.58 and 2.54 respectively. The force of 42 Ton was determined for the bearing-shaft assembly process; This being the one with the highest demand for the hydraulic press. It was concluded that an operation manual, security, and maintenance are very important for the use of the hydraulic press to minimize a general repair.
