Title (EN) VALVE GUIDE REAMER
(FR) ÉLARGISSEUR DE GUIDE DE SOUPAPES
(PT) ALARGADOR DE GUIA DE VÁLVULAS
Abstract: front page image
(EN)The present invention relates to a valve guide reamer, used in the field of mechanics, and more specifically to a valve guide reamer with a helical geometry that is used in the finish machining of poppet valve guides in motor vehicles to form the guide hole, which is concentric with the valve seat ring. The reamer is formed by a cylindrical body provided with an internal central hole (FC) and internal radial holes (FR) for cooling and conveying the chips out of the admission/exhaust duct (D), the reamer having two regions: a cutting region (1) and a guide region (2), both having helical geometries and being separated by a small channel (3), wherein, at the end, the cutting region (1) has a right-hand helical cutting geometry and the guide region (2) has a left-hand helical geometry.
(FR)La présente invention concerne un élargisseur de guide de soupapes, appartenant au domaine mécanique, et notamment un élargisseur de guide de soupapes de géométrie hélicoïdale trouvant une application dans l'usinage de finition de guides de soupapes de culasses de moteurs automobiles pour produire le trou du guide, concentrique par rapport à l’anneau siège de soupape. L’élargisseur est formé par un corps cylindrique doté intérieurement de trous central (FC) et radiaux (FR) pour le refroidissement et l’acheminement des résidus fragmentaires vers l’extérieur du conduit d'admission/échappement (D), comportant deux zones, l’une de coupure (1) et l’autre de guidage (2), qui présentent toutes deux des géométries hélicoïdales, séparées par un petit canal (3). En extrémité, la zone de coupure (1) présente une géométrie de coupure hélicoïdale droite et la zone de guidage (2) présente une géométrie hélicoïdale gauche.
(PT)Trata-se a presente invenção de um alargador de guia de válvulas, pertencente à área mecânica, mais particularmente trata-se de um alargador de guia de válvulas com geometria helicoidal aplicado na usinagem de acabamento de guias de válvula de cabeçotes de motores automotivos para gerar o furo da guia, concêntrico com o anel sede de válvula. O alargador é formado por um corpo cilíndrico, dotado internamente de furos central (FC) e radiais (FR) para refrigeração e condução dos cavacos para fora do duto de admissão/escape (D), o qual compreende duas regiões, uma de corte (1) e outra de guia (2), ambas com geometrias helicoidais, separadas por um pequeno canal (3), onde na extremidade, a região de corte (1) é dotada de uma geometria de corte helicoidal direita e a região de guia (2) é dotada de uma geometria helicoidal esquerda.
