Diseño de matrices para conformar herrajes usados en la junta viga – columna de estructuras livianas.

Abstract

To ensure the stability and safety of metal constructions, these fittings must meet precision and strength standards, especially in structural systems such as “Steel Framing”. Although advances have been made in metal forming processes, there are still challenges in the efficient manufacture of high-precision fittings. Dies were designed to form fittings used in beam-column joints in light structures. To this end, a detailed analysis of the forming processes was carried out, and the operations involved in the manufacture of fittings were studied. In addition, a progressive die was designed and simulated using the software involved in order to ensure efficiency and precision in the production of fittings. Within the simulation of the dies, it was necessary to choose between various catalogues to select the components that best fit the forming process that was intended to be achieved. In addition, applicable regulations were considered in each component of the die, trying to guarantee its durability and required standards, in order to have a processing of the parts involved. The cost of each component was evaluated in order to have an economic approach and economic feasibility. The simulations allowed to evaluate the effects of operations such as punching, cutting and bending, optimizing the design of the dies to minimize defects in the manufactured fittings. Additionally, the cost of construction of the dies was analyzed and their economic investment was verified, ensuring their viability and efficiency in the manufacturing process.
