    Rediseño de prensa oleo hidráulica y sistema de control para conformado de tubo para la empresa metalmecánica Casimiros en la ciudad de Puyo

    This technical project explains, in an orderly and systematic sequence, the redesign of an oil-hydraulic press for forming galvanized tubes 1 inch in diameter and 2 millimeters thick. The shaping of this material initially depends on the skill and strength of the worker; however, it seeks to improve the process by controlling the limit switch, in addition to eliminating the operation of force through the use of a hydraulic cylinder. In the present, the determination of parameters was carried out by establishing ranges: pressures, end-of-stroke adjustments and piston advance speed. Necessary elements and devices were calculated through bibliographic research, in addition to the calculation of: loads and dimensions. Consecutively, components were selected for the three systems: structural, oil-hydraulic and control; mechanisms which are based both on the established parameters and on the calculations made. The validity of the project was also determined through performance tests that provide an error of less than 1 percent and a forming time of 10 seconds per piece. At the end of the project, an oil-hydraulic press with a control system capable of performing 340 shapes per hour, with end-of-run control and drive by electric panel, was delivered to the ¨Casimiros¨ metalworking company.
