Title (EN) ROTARY TOOL AND JOINING METHOD
(FR) OUTIL ROTATIF ET PROCÉDÉ D'ASSEMBLAGE
(JA) 回転ツール及び接合方法
Abstract:
(EN) The present invention addresses the problem of providing a rotary tool (1) and a joining method which are capable of reducing the size of a recess groove in the surface of a metal member (20) and decreasing the surface roughness of a joint surface. This rotary tool (1) for friction stirring provided with a base end-side pin (3) and a tip-side pin (4) is characterized in that: the taper angle of the base end-side pin (3) is greater than the taper angle of the tip-side pin (4); and a stair-like stepped part (10) is formed on the outer peripheral surface of the base end-side pin (3). The friction stirring is performed while pressing the surfaces of the metal members (20, 20) by means of the base end-side pin (3).
(FR) L'invention concerne un outil rotatif (1) et un procédé d'assemblage permettant de réduire la taille d'une rainure d'embrèvement dans la surface d'un élément métallique (20), et de diminuer la rugosité de surface d'une surface de joint. Cet outil rotatif (1) de brassage par friction, qui est équipé d'une broche côté extrémité de base (3) et d'une broche côté pointe (4), se caractérise en ce que: l'angle de conicité de la broche côté extrémité de base (3) est supérieur à l'angle de conicité de la broche côté pointe (4); et une pièce à gradins de type escalier (10) est formée sur la surface périphérique externe de la broche côté extrémité de base (3). Le brassage par friction est accompli en même temps qu'une pression est appliquée sur les surfaces des éléments métalliques (20, 20) au moyen de la broche côté extrémité de base (3).
(JA) 金属部材（２０）の表面の凹溝を小さくすることができるとともに、接合表面粗さを小さくすることができる回転ツール（１）及び接合方法を提供することを課題とする。基端側ピン（３）と、先端側ピン（４）とを備える摩擦攪拌用の回転ツール（１）であって、基端側ピン（３）のテーパー角度は、先端側ピン（４）のテーパー角度よりも大きくなっており、基端側ピン（３）の外周面には階段状の段差部（１０）が形成されていることを特徴とする。基端側ピン（３）で金属部材同士（２０，２０）の表面を押えながら摩擦攪拌を行う。
