Title (EN) REMOVABLE CUTTING BLADES FOR A HELICAL CUTTERHEAD
(FR) LAMES COUPANTES AMOVIBLES POUR UNE TETE DE COUPE HELICOÏDALE
Abstract:
(EN) A removable cutterhead insert (18) for use in a helical cutterhead (10) for an industrial woodworking machine, the helical cutterhead (10) including a generally cylindrical portion (16), a plurality of circumferential, spaced grooves (17) extending into the cutterhead body from the periphery of the cylindrical portion (16) and adapted to receive the removable cutterhead inserts (18), and fasteners for removably securing the cutterhead inserts in the grooves (17); the cutterhead insert (18) includes a mild steel insert body (22) and two blade units (24); the insert body (22) having raised portions having triangular pockets formed therein so as to have two inwardly-facing flat portions, a hole to receive the fasteners for removably securing the cutterhead insert in the grooves between the inwardly-facing flat portions and two bolt holes to secure the two blade units to the insert body; and the blade units are triangular with cut-off corners (36) each including a blade edge (38) and configured so as not to occlude the countersunk hole and to have the blade edges disposed to align with the blade edges of other blade units.
(FR) L'invention concerne un élément d'insertion amovible (18) pour une tête de coupe hélicoïdale (10) destinée au travail industriel du bois. La tête de coupe (10) comprend une portion sensiblement cylindrique (16), une pluralité de rainures circonférentielles espacées (17), s'étendant dans le corps de la tête de coupe depuis la périphérie de la portion cylindrique (16) et permettant de loger des éléments d'insertion amovibles (18) et des dispositifs de fixation pour immobiliser d'une manière amovible les éléments d'insertion dans des rainures (17). L'élément d'insertion (18) a un corps d'insertion en acier doux (22) et deux unités de lame (24). Le corps d'insertion (22) a des portions surélevées ayant des poches triangulaires formées de manière à avoir deux portions plates tournées vers l'intérieur, un trou pour recevoir des dispositifs de fixation pour immobiliser de manière amovible l'élément d'insertion dans les rainures, entre les portions plates tournées vers l'intérieur et deux trous à vis, pour immobiliser les deux unités de lame sur le corps d'insertion. Les unités de lame sont triangulaires avec des coins coupés (36) et chacune de ces unités a un bord de lame (38) et est réalisée de manière à ne pas fermer le trou bordé et à avoir ses bords de lame alignés avec les bords de lame des autres unités de lame d'autres corps d'insertion.
