Diseño y construcción de un troquel de corte y perforado de platina metálica de espesor 1/8 de pulg. para la empresa ingeniería del acero y matricería en la ciudad de Ambato provincia de Tungurahua

Abstract

The main objective of this project is to develop a methodology for the design and construction of dies that perform cutting and punching operations. It also allows the reader to understand how the optimization criterion works, creating a model using the Finite Elements method that facilitates the cutting process and perforated for a metal plate that has 1/8 inch of thick. For which a series of mechanical Traction and Bending tests were carried out, using the ASTM E8-16a and ASTM E290-14 standards respectively, to determine the properties of AISI SAE D3 steel commercially known as BOHLER K 100, steel selected for construction of the die To carry out the optimization of the punching process, series of simulations were carried out using a Finite Element software to determine the geometry of the punches that produces the least possible cutting effort when these operations are carried out. The results obtained through the simulations carried out by alternating the geometry of the punches allowed to determine values of the shear stress produced, from which the lowest value obtained was selected, which represents a reduction of 62% in relation to the effort obtained when the operation was simulated whit any specific geometry of the drilling punch.
