Abstract

　プラグ１は、第１円柱部２０と、テーパ部３０と、第２円柱部４０とを備える。第１円柱部２０は外径Ｄ１を有する。第２円柱部４０は、外径Ｄ１よりも大きい外径Ｄ２を有する。テーパ部３０は、第１円柱部２０と第２円柱部４０との間に形成される。テーパ部３０は、第１円柱部２０から第２円柱部４０に向かって徐々に大きくなる外径を有するテーパ表面３１と、軸方向長さＬとを有する。プラグ１の外径Ｄ１及びＤ２と、軸方向長さＬとはさらに、式（１）～（４）を満たす。そのため、本発明による冷間引抜プラグは、冷間引抜加工後の金属管の外面の引張残留応力を低減できる。 　０．２５≦ρ≦２．００　（１） 　０．０６≦Ｌ／Ｄ２≦０．８　（２） 　Ｌ／Ｄ２≦０．３×ρ＋０．５７５　（３） 　Ｌ／Ｄ２≧０．１×ρ　（４） 　ここで、ρ＝（Ｄ２－Ｄ１）／Ｄ１×１００である。
