Diseño y construcción de una rectificadora -afiladora con control automático de cuchillas planas

Abstract

Based on the bibliographic research, it was determined that in Ecuador, the sharpening machines are entirely manual, which is why this research proposes improving this methodology by adapting bibliographic and career concepts to carry out an optimal design and correct automation. The 3D design used SolidWorks software, for the simulation of efforts and calculate forces, tolerances, and safety factors; the ANSYS software and specialized software complemented it. In addition, ANSYS was used for verify the mesh quality and Convergence analysis, and complementary software was to verify convergence and welds. For the correct selection of materials and processes, the VDI 2221 standard was used, which made it possible to balance different proposed solutions and select the one that best suits our technical and economic needs. The work highlights the knowledge of Machine Elements Design for the design of the power screws used, as well as the selection of materials such as Bearings, the pinion and Catalina of the transmission, and the chain necessary to use, among other elements. A mechanical method was used for process to provide automatic movement with the actuation of limit switches that would allow the mobile reel to move from side to side. Finally, functional tests were carried out in which correct operation of the equipment was evidenced by carrying out tests with blades of different sizes, emphasizing the 3 mm blades, thus obtaining a conclusion that for these blades, two passes will be required to complete their sharpening and that two additional passes will be required for every 5 mm increase in blade thickness.
