Diseño e implementación de un sistema de control para una prensa hidráulica basado en PLC LOGO y HMI.

Abstract

This project collects information generated in the process of construction of a PLC controlled oil hydraulic press by means of LOGO and HMI, in this way, through applied research, the materials and characteristics suitable for its execution were determined, as the first stage of the procedure. It was decided the type of press and the function to be carried out, to then determine the oil-hydraulic accessories, work capacity and the operation of an oil-hydraulic circuit, on the other hand, the PLC LOGO and HMI controller was also determined together with the devices inlet and outlet available for the type of function to be performed in conjunction with the electrical and oleohydraulic system. As a next step, the mechanical, oleohydraulic, electrical connection circuit was designed for the control of the press and the programming of the PLC LOGO, then functional tests were carried out simulating the systems in specialized design platforms in each of the areas that make up the project to rule out possible failures and errors to the point of being approved to give way to the construction process. The construction began with the machining of the parts that make up the mechanical set of the press, construction of the structure where the press works, adaptation of the parts that make up the oleohydraulic system to make way for the assembly process and continue with the construction and installation of the electrical system in conjunction with the programming of the PLC LOGO, as a final procedure was the adaptation of materials and assembly to provide the practical tests of the systems as a whole.
