(KO) 급유식 펀치
Abstract:
(EN) The present invention relates to a punch for making holes in a thin sheet material made of metal and the like, the punch having excellent durability since lubricating oil can be supplied to the outer surface of the end portion of the punch. The punch comprises: a body comprising a punching part positioned at one side thereof in the longitudinal direction and a supporting part positioned at the other side thereof in the longitudinal direction; a lubricating oil passage formed to penetrate the inside of the body in the longitudinal direction, and having one or more outlets on the outer surface of the punching part; and a lubricating oil supply control means for opening and closing the outlets of the lubricating oil passage.
(FR) La présente invention se rapporte à un poinçon pour la formation de trous dans un matériau sous forme de feuille mince constitué de métal et similaire, le poinçon ayant une excellente durabilité étant donné que de l'huile lubrifiante peut être apportée à la surface externe de la partie d'extrémité du poinçon. Le poinçon comprend : un corps sur un côté duquel se trouve une partie de poinçonnage dans la direction longitudinale et une partie de support située de l'autre côté dans la direction longitudinale; un passage d'huile lubrifiante formé pour pénétrer à l'intérieur du corps dans le sens longitudinal et ayant une ou plusieurs sorties sur la surface externe de la partie de poinçonnage; et un moyen de commande d'alimentation en huile lubrifiante pour l'ouverture et la fermeture des sorties du passage d'huile lubrifiante.
(KO) 본 발명은 금속 등으로 이루어지는 얇은 판재에 구멍을 형성하기 위한 펀치에 관한 것으로서, 펀치 단부의 외면에 윤활유를 공급해줄 수 있어 우수한 내구성을 갖는다. 상기 펀치는, 길이방향의 일측에 위치한 펀칭부와 길이방향의 타측에 위치한 지지부로 이루어지는 몸체; 상기 몸체의 내부를 길이방향으로 관통하여 형성되며, 펀칭부의 외면 상에서 1개 이상의 출구를 가지는 윤활유통로; 및 상기 윤활유통로의 출구를 개폐하는 윤활유공급조절수단;을 포함하여 구성되는 것을 특징으로 한다.
