Abstract

Procedimiento para la producción de un componente de acero con zonas de distinta dureza o ductilidad, en el que o bien a partir de una pletina, la chapa de acero se conforma en frío en una herramienta obteniendo un componente (1) y el componente (1) conformado se calienta a continuación a una temperatura por encima de la temperatura de austenización y, para su temple, se coloca en una segunda herramienta (2) que consta de dos mitades y se templa por enfriamiento brusco en la segunda herramienta (2) o se calienta una pletina a una temperatura por encima de la temperatura de austenización y, a continuación, para la conformación y temple por enfriamiento brusco, se coloca en una herramienta de conformación (2) con dos mitades de herramienta y ahí se conforma y se templa por enfriamiento brusco, caracterizado por que o bien en el temple por enfriamiento brusco, en las zonas en las que se quiere mantener una dureza menor o una mayor ductilidad, se aplica energía en estas zonas con al menos una bobina de inducción (9, 10) de tal forma que se produce un temple por enfriamiento brusco reducido o nulo, de modo que la refrigeración se lleva a cabo a una velocidad por debajo de la velocidad crítica de temple o bien se mantiene la temperatura en esta zona al nivel más elevado que se desee hasta el desmoldeo o el componente (1) templado, tras desmoldearlo, se coloca sobre o en otro molde en o sobre el que se actúa sobre el componente (1) inductivamente de tal forma que el temple existente se elimina parcial o completamente.
