Trefilagem, ou Trefilação, é o processo de fabricação de arame e barras finas de metal. É um processo industrial que acarreta na redução da seção transversal (largura) e respectivo aumento no comprimento do material. Consiste na Tração da peça através de uma matriz chamada fieira ou trefila, com forma de canal convergente.. O processo de trefilação consiste em puxar o metal ...
Los diámetros de los conos son tales, que generan una secuencia de velocidades periféricas equivalentes a una serie definida de reducciones de tamaño. Máquina Trefilador con dados escalonados No es posible lograr una relación precisa entre los diámetros del dado y del bloque que es esencial en este patrón, pero el estirado puede llevarse ...

Un alambre se estira a través de un dado con un ángulo de entrada = 15º. El diámetro inicial es 2.5 mm y el diámetro final es 2 mm. El coeficiente de fricción en la interfase trabajo-dado es 0.07. El metal tiene un coeficiente de resistencia K = 207 MPa y un exponente de endurecimiento por deformación n = 0.20. Determine el esfuerzo de
