Diseño y construcción de máquina rotativa de corte longitudinal de planchas de acero galvanizado de 1 mm de espesor en la empresa Carrocerías “IBIMCO S.A.”

Abstract

For the execution of the project the shear cutting process was investigated by means of an unconventional system which allows longitudinal cuts of dimensions larger than those established for a standard metal plate, from which different design alternatives were determined. Of these, the circular blade cutting system was selected as the main mechanism, which consists of a combined transmission of chains, catars, pulleys and belts, as well as a power reducer and a three-phase electric engine. The parameters specific to parts and components were designed taking into account the actual conditions on which the machine will work in addition to safety factors recommended by entities such as ASTM-HANDBOOK. Once the design and construction were carried out, the functional tests were carried out where it was verified that with the implementation of the machine clean cuts can be made with minimum tolerances, reducing the 40% of time during the cutting process in relation to the conventional process used in the company.
