Claims (3)
- 鉄筋の端部を塑性変形容易な温度に加熱し、その加熱によって形成した加熱領域側の鉄筋端面を、形成すべき拡径部の外側端面を成形するための成形面であって半径方向外方への材料の流れを助成するための隆起部を備えた成形面を有する型の前記成形面に押し付けると共に加熱領域に鉄筋軸線方向の圧縮力を作用させ、外径が増大するように塑性変形させて拡径部を形成することを特徴とする定着部付鉄筋の製造方法。
- 前記型に更に、形成すべき拡径部の外周面を規制する外周面用の成形面を設けておき、前記鉄筋の端部を外径が増大するように塑性変形させて拡径部を形成した際に同時に該拡径部の外周面を前記外周面用の成形面で成形することを特徴とする請求項1記載の定着部付鉄筋の製造方法。
- 前記鉄筋端部に拡径部を形成した後、その拡径部を型押し成形して、拡径部の内側端面の周縁部に係止突起を形成することを特徴とする請求項1又は2記載の定着部付鉄筋の製造方法。
