Abstract

Cette invention concerne un procédé et un appareil permettant l'application automatique d'une couche uniforme de fumage sur la surface des chemises en fer utilisées pour la fabrication de monoblocs destinés aux moteurs à combustion interne. L'appareil susmentionné est composé des éléments suivants: une cabine fermée qui contient au moins deux plateaux conçus pour disposer les chemises en fer; un robot automatisé équipé d'un brûleur qui produit une flamme d'acétylène; une cheminée permettant l'évacuation des fumées produites par la flamme en dehors de la cabine; une porte automatique permettant l'accès régulé des plateaux dans la cabine; et un bras mécanique conçu pour permettre le retrait des chemises en fer posées sur les plateaux sans endommager la superficie fumée.
