造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a fish hook, particularly a fish hook mainly intended for cutlassfish.

ものである。(Prior Art) A fishhook as shown in FIG. 4 exists as an example of a conventional fishhook for hairtail fish. This is a lead weight (2) with the base end of the hook body (1) made of lead.
), and a threading ring (3) etc. are also integrally attached to this weight (2) in an appropriate direction. The conventional general manufacturing method for fishing hooks having such a structure is to form the hook body (1) and other parts, excluding the weight (2), into one piece by bending them using a single narrow rod-shaped steel rod. The proximal end of the lead is placed in a mold and molten lead is poured into the outer periphery of the mold.

鋳型を多数備えないかぎり作業の停滞をまねき工程の円
滑な進捗が妨げられる傾向があり非効率的となる。(Problems to be Solved by the Invention) According to this manufacturing method, it is necessary to maintain the required posture of the fishing hook in the sea, so the positions of the hook body (1), threading ring (3), etc. must be adjusted. Taking this into consideration, as shown in FIG. 4, a single small diameter rod made of steel must be bent in a complicated manner, making it extremely troublesome to form. Furthermore, the inclusion of casting in the manufacturing process is inefficient, as unless a large number of molds are provided, the work tends to stagnate and the smooth progress of the process is hindered.

本発明は斯る点を改良し、製造が簡便で能率化を図るこ

である。(Means for Solving the Problems) In order to achieve the object of the present invention, the necessary attachment members for the weight (2), such as the hook body (1) or the threading ring (3), are separated into appropriate separate bodies. A fastening hole (41 (4
)' is formed separately, and a hook body (1) or a threading ring (3
), etc., and then press the outer surface of the weight (2) to crush the fixing hole (41 (41') and press its inner wall against the outer surface of the attached member, thereby attaching each attached member. It is characterized by being fixed in place so that it cannot be removed.

除去できるようにしたものである。(Function) In the present invention, the manufacturing process of the weight and the manufacturing process of attachment members such as the hook body and the threading ring are separated, and the parts formed in each manufacturing process are integrated in the assembly process to complete the process. This makes it possible to eliminate the manufacturing process of casting the weight, which was conventionally included, from the assembly process.

。(Example) FIGS. 1 to 3 show examples of the present invention. FIGS. 1 and 2 are cross-sectional views showing the manufacturing process, and FIG. 3 is a perspective view of the finished product. First, a small diameter rod made of steel has a U-shaped threading R (3), a hook part (5) at the lower end (see Figure s), and a folded part (6) at the top end. The folding piece (the hook body (1), which is also made of a narrow rod-shaped body made of steel and bent in the opposite direction of the hook part (5) with a sharp tip), is formed separately as a single unit. The front and rear surfaces are circular, the side surfaces are spindle-shaped, and there are fixing holes f/ at 90° apart on the peripheral edges facing toward the center.
11 (41') A lead weight (2) is formed separately, and the threading ring (3) is inserted from the open end side, and the hook body (1) is inserted from the folded part (6) side of the top end. It is inserted into the fixing holes f41 f41' of the weight (2) in the direction of the arrow in Figure 1, and then pressed in the front and rear directions of the weight (2), that is, in the direction of the arrow in Figure 2. Attachment hole (41
(41' is crushed and its inner wall is the threading ring (3) and the hook body (
1) is pressed into contact with the side surface and is fixed in an unremovable manner.

（効　果） 本発明は上述した構成を有するため以下の如き効果を得

来のように一本の素材を複雑に折曲する必要がなくなり
製造が簡便化する。(Effects) Since the present invention has the above-described configuration, it obtains the following effects. First, since the threading ring and the hook body are formed separately, there is no need to bend a single piece of material in a complicated manner as in the past, which simplifies manufacturing.

特に糸通し環と鉤体の角度を変化させたい場合等には従
来の方法では折曲機の構成を変化させる必要があるが本
発明ではこのような場合に影響がない。次に従来は組立
工程中に錘の鋳込による製造工程が含まれていたためこ

発明では錘の鋳込による製造工程が除かれたため組立工
程が円滑化する。本発明は以上のように釣針の製造が極
めて効率化できる著効を有するものである。In particular, when it is desired to change the angle between the threading ring and the hook body, the conventional method requires changing the configuration of the bending machine, but the present invention has no effect on such cases. Next, in the past, the manufacturing process by casting weights was included in the assembly process, which had the disadvantage of slowing down the entire flow, but in the present invention, the manufacturing process by casting weights was removed, so the assembly process is facilitated. As described above, the present invention has the remarkable effect of making the production of fishhooks extremely efficient.
