Abstract |
AB |
[EN] A process is disclosed for producing a ski edge made of quenched and subsequently tempered steel having a head (2) that comprises the running surface and a flank (4) that projects into the body of the ski. The profiled edge (1) is at first rolled, then quenched and subsequently tempered over its whole cross-section. Afterwards, the flank (4) is partially tempered and provided in a separate operation with punched out openings. In order to obtain with this process a totally straight ski edge, the deviation in Rockwell hardness, seen in the direction of the cross-section and length of the profiled edge is set at less than 2 HRC during quenching and subsequent tempering of the whole profiled edge. The warming-up temperature and duration during partial warming-up of the edge are the same over the whole length of the profiled edge and the profiled edge is subjected to a constant bending strain before being punched.
[FR] L'invention concerne un procédé de fabrication d'une carre de ski en acier d'amélioration qui comprend une tête (2) pourvue d'une surface de portée et un flanc (4) qui s'enfonce dans le corps du ski. La carre profilée (1) est d'abord laminée et améliorée par trempe et revenu sur toute sa section transversale. Ensuite, le flanc (4) est soumis à un revenu partiel et, au cours d'une seconde opération, pourvu d'ouvertures poinçonnées. Afin d'obtenir avec ce procédé une carre de ski parfaitement droite, il est prévu que l'écart de la dureté Rockwell, dans le sens de la section transversale et dans la longueur de la carre profilée, soit fixé à moins de 2° HRC pendant le traitement d'amélioration de la carre profilée complète. La température de réchauffement et le temps de réchauffement pendant le réchauffement partiel de la carre sont les mêmes pour toute la longueur de la carre profilée et la carre profilée est soumise à une déformation de flexion constante avant le poinçonnage. |
