Abstract
Un método para fabricar un clip de riel flexible que comprende doblar una barra hecha de metal, que tiene un valor de dureza que cae dentro de un rango de valores de dureza conocido, en una forma predeterminada y luego someter la barra doblada a un proceso de endurecimiento en frío con el fin de inducir en la barra doblada una cantidad predeterminada de endurecimiento permanente, caracterizado porque el proceso de endurecimiento en frío comprende: aplicar una primera carga a parte de la barra doblada con el fin de provocar una primera cantidad de desvío de esa parte de la barra doblada, cuya primera carga es una carga predeterminada que tiene un valor igual a o mayor que el requerido para alcanzar el punto de flexión de metal que tenga el valor más alto de dureza en dicho rango de valores de dureza; medir la primera cantidad de desvío de dicha parte de la barra doblada que se logra al aplicar la primera carga predeterminada; determinar, con base en la cantidad de desvío medida, ya sea (i) una segunda carga que, cuando se aplica a dicha parte de la barra doblada, provocará que la barra doblada adquiera la cantidad predeterminada de endurecimiento permanente, o (ii) una segunda cantidad de desvío de dicha parte de la barra doblada requerida con el fin de producir en la barra doblada la cantidad predeterminada de endurecimiento permanente; y aplicar la segunda carga determinada a dicha parte de la barra doblada o desviar dicha parte de la barra doblada mediante la segunda cantidad de desvío determinada.A method for manufacturing a flexible rail clip comprising bending a bar made of metal, which has a hardness value that falls within a range of known hardness values, in a predetermined manner and then subjecting the bent bar to a process of cold hardening in order to induce a predetermined amount of permanent hardening on the bent bar, characterized in that the cold hardening process comprises: applying a first load to part of the bent bar in order to cause a first amount of deflection of that part of the bent bar, whose first load is a predetermined load that has a value equal to or greater than that required to reach the metal bending point having the highest hardness value in said range of hardness values; measuring the first amount of deflection of said part of the bent bar that is achieved by applying the first predetermined load; Determining, based on the amount of deviation measured, either (i) a second load which, when applied to said part of the bent bar, will cause the bent bar to acquire the predetermined amount of permanent hardening, or (ii) a second amount of deflection of said part of the bent bar required in order to produce in the bent bar the predetermined amount of permanent hardening; and applying the second determined load to said part of the bent bar or diverting said part of the bent bar by means of the second amount of deflection determined.
