PROBLEM TO BE SOLVED: To provide a method of manufacturing a squid-fishing hook, which enables the continuous and efficient execution of work for molding parts from a coil wire rod to a squid hook having acute parts at both ends, respectively.SOLUTION: A cut material of a predetermined size is formed from a coil wire rod A, and a squid hook semi-molding is formed by heading-molding an acute part in a step-by-step manner at one end of the cut material by a header 3. Subsequently, component rolling is applied to the other end of the squid hook semi-molding by a rolling machine 4 in a post-process to form the acute part and form a squid hook having the acute parts at both ends.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】コイル線材から両端部に尖鋭部をもつイカ針までの成形作業を連続的にかつ効率よく行うことが出来るイカ釣針の製造方法の提供。【解決手段】コイル線材Aから所定寸法の切断素材を形成すると共にヘッダー3により切断素材の一端部に段階的に尖鋭部を圧造成形してイカ針半成形品を形成し、その後、後工程でイカ針半成形品の他端部に転造盤4で転造加工を施し尖鋭部を形成して、両端部に尖鋭部をもつイカ針を形成するようにした。【選択図】図1
