Title (EN) DUST COLLECTION COVER ATTACHABLE TO CUTTER
(FR) COUVERCLE DE COLLECTE DE POUSSIERES FIXABLE A UN DISPOSITIF DE COUPE
Abstract:
(EN) A dust collection cover (1) capable of efficiently collecting cutting chips and residues generated as a result of cutting a workpiece (3). A cutter (2) includes a motor and a rotary blade (4) driven by the motor, and the dust collection cover (1) is attached to the cover for covering a part of the blade (4). The cover (1) is formed with a dust discharge port (12) through which cutting chips and residues are discharged. The cover (1) has a guide arrangement (24, 25, 27, 33, 34) for directing the cutting chips and residues toward an interior of the cover body. The arrangement provides a blowing-out air (27) blowing to the workpiece (3), or a rod-like member (33) removing the cutting chips and residues.
(FR) L'invention concerne un couvercle (2) de collecte de poussières capable de collecter efficacement les copeaux et les résidus de coupe générés du fait de la coupe d'une pièce à usiner (3). Un dispositif de coupe (2) comprend un moteur ainsi qu'une lame rotative (4) entraînée par le moteur et le couvercle (1) de collecte de poussière est fixé au couvercle destiné à couvrir une partie de la lame (4). Le couvercle (1) comprend un orifice (12) de décharge des poussières par lequel les copeaux et les résidus de coupe sont déchargés. Le couvercle (1) présente un système de guide (24, 25, 27, 33, 34) destiné à diriger les copeaux et les résidus de coupe vers une partie intérieure du corps du couvercle. Le système produit de l'air de soufflage extérieur (27) soufflant sur la pièce à usiner (3) ou un élément en forme de tige (33) retirant les copeaux et les résidus de coupe.
