Abstract

Se proporciona un método de formación de una porción de inicio de fractura de una varilla de conexión para formar porciones de inicio de fractura de una varilla de conexión en posiciones opuestas en una superficie periférica interna de un extremo grande de la varilla de conexión 1 hecha de metal, que incluye un primer paso de formación de una porción de ranura 11 en una posición correspondiente a la porción de inicio de fractura usando una primera punta de inserto con un extremo de punta grande R y un segundo paso de formación de la porción de inicio de fractura la cual se ha convertido en una ranura en forma de V 12 por maquinación de una porción inferior R de la porción de ranura más pequeña usando una segunda punta de inserto que tiene un extremo de punta R más pequeño que la primera punta de inserto.
