付設した発火ヤスリの製造方法に関する。Detailed Description of the Invention (Field of Industrial Application) This invention relates to a firing file for a lighter, and a firing file having a rotating collar and a mounting shaft integrally attached to both sides of a cylindrical file body. Regarding the manufacturing method.

者を一体化してライタ一本体に軸支する。(Prior Art) In the case of a specific VT type lighter, such as a Zippo type lighter or a disposable lighter, ignition is performed by rotating the ignition file directly with a finger. Such a firing file, which can be rotated directly with the fingers, has a cylindrical file body with disk-shaped rotating collars with a larger diameter than the file body attached to both sides of the file body, and the two are integrated into one lighter body. Pivotally supported.

ラーとを一体化している。In the case of such a firing file known in the United States that can be rotated directly with fingers, the file main body and the rotating collar are generally formed separately, and the two are joined and integrated. It is formed into a shape with pongee holes or four circular parts on both sides, and collars are fitted to the outer periphery of both ends of the file body, or the shaft part or cylindrical protrusion of the rotating collar is fitted into the shaft, hole or recess. The file body and collar are integrated by being forcibly inserted.

。Such a file known in the United States in which the file body and collar are separate is 51! The number of manufacturing steps increases, making it difficult to reduce costs, and the generation of residual materials, making it impossible to use materials without wastage. In particular, when manufacturing a cylindrical file body by cold forging, the punched part of the punching process becomes leftover material, and in the past, this leftover material could not be used effectively, so it was discarded. This is the current situation.

。(Problems to be Solved by the Invention) If the file main body, rotating collar, and mounting shaft are integrally molded from one material, the generation of residual material seen in conventional products can be prevented. It was difficult to make the file surface an accurate linear surface parallel to the central axis, and it was also difficult to accurately align the central axis of the rotating collar and shaft with the central axis of the file part. . Misalignment of the rotation collar or the center axis of the details with respect to the file part makes it impossible to rotate the firing file accurately, causing a problem that it becomes impossible to accurately rub the flint stone.
