Title (EN) BROACHING TOOL
(FR) OUTIL DE BROCHAGE
(JA) ブローチ工具
Abstract:
(EN) An aspect of a broaching tool of the present invention is provided with a plurality of processing blade parts aligned along a central axis extending in the vertical direction. Each of the processing blade parts has a plurality of teeth sections protruding outward in a radial direction. The plurality of teeth sections are arranged in parallel along the peripheral direction for each processing blade part, and are each arranged in parallel along the teeth section and the axial direction of different processing blade parts. Each of the teeth sections has a rake face that faces the lower side thereof, and a flank face provided over the entire periphery of the circumferential direction side surface of the teeth sections and having a relief angle of greater than 0°. The plurality of processing blade parts are separate members from each other.
(FR) Selon un aspect, la présente invention concerne un outil de brochage pourvu d'une pluralité de parties de lame de traitement alignées le long d'un axe central s'étendant dans la direction verticale. Chacune des parties de lame de traitement présente une pluralité de sections de dents faisant saillie vers l'extérieur dans une direction radiale. Les plusieurs sections de dents sont agencées en parallèle le long de la direction périphérique pour chaque partie de lame de traitement, et sont chacune agencées en parallèle le long de la section de dents et de la direction axiale de différentes parties de lame de traitement. Chacune des sections de dents a une face de dépouille qui fait face à leur côté inférieur, et une face de flanc disposée sur toute la périphérie de la surface latérale de direction circonférentielle des sections de dents et ayant un angle de dépouille supérieur à 0°. Les plusieurs parties de lame de traitement sont des éléments séparés les uns des autres.
(JA) 本発明のブローチ工具の一つの態様は、上下方向に延びる中心軸に沿って並ぶ複数の加工刃部を備える。加工刃部のそれぞれは、径方向外側に突出する複数の歯部を有する。複数の歯部は、加工刃部ごとに周方向に沿って並んで配置され、かつ、それぞれ他の加工刃部の歯部と軸方向に沿って並んで配置される。歯部のそれぞれは、下側に面するすくい面と、歯部の周方向側面に全周に亘って設けられ、逃げ角が0°より大きい逃げ面と、を有する。複数の加工刃部は、互いに別部材である。
