Abstract

Procedimiento de corte en dientes de sierra por cizallamiento del alma de perfiles que consiste en hacer avanzar paso a paso el perfil entre dos útiles de cizallamiento fijados a los platos de una prensa, estando caracterizado este procedimiento por el hecho de que los útiles de cizallamiento incluyen una zona de cizallamiento que se extiende en la longitud de un paso de los dientes y en la cual cada arista de cizallamiento de un útil es sensiblemente paralela a la arista correspondiente del otro útil, y una zona de transición, que precede a la zona de cizallamiento en el sentido del avance del perfil, y en la cual las aristas de cizallamiento correspondientes van divergiendo con objeto de que el cizallamiento sea completo en la proximidad de la zona de cizallamiento y sea nulo por el lado de la entrada, estando regulada la carrera de la prensa al mínimo necesario para obtener el cizallamiento en la zona de cizallamiento.
