When a bolt material with a circular head rotates between both rolling dies, a thread rolling device that forms a thread on the outer periphery of the shaft of the bolt material by rolling or corrects the thread, The fixed rolling die side is normally elastically abutted on the outer periphery of the head of the bolt material via an elastic member, and the inspection lever that swings due to the eccentricity of the head relative to the center of the shaft of the bolt material can be swung. And a sensor that detects the amount of eccentricity with respect to the shaft center of the head by swinging the inspection lever, and discriminates between good and defective products based on the detection results of this sensor, and defective products Is excluded separately from good products There is that the thread rolling apparatus comprising a defective elimination means for (a range of utility model registration claims).

そして、前記従来技術は、ねじ転造装置で一次転造されたねじ素材が、後工程で熱処理、メッキ等を施した際にねじ山に打痕等の凹凸傷が発生したのを、再度ねじ転造装置に通して、二次転造することによりねじ山を修正加工するようにしている。   In the prior art, when the screw material that was primarily rolled by the screw rolling device was subjected to heat treatment, plating, etc. in a subsequent process, unevenness such as a dent was generated on the screw thread. The thread is corrected by secondary rolling through a rolling device.

The fixed pressing member 5 is formed of an elastic synthetic resin (elastic resin 5A) such as urethane, polystyrene, or polypropylene, and both of them are elastically pressed against the roller rolling die 2 with the screw material 4 therebetween. Hold between. Further, since the screw material 4 has already been formed with a thread and a thread valley by primary rolling, the fixed pressing member 5 is deformed so as to enter the thread valley by being elastically pressed.

次に、前記ねじ補修装置1Aによるねじ補修作用を説明する。
ねじ転造やメッキ等の後処理の際に打痕(凹凸傷)等が生じたねじ素材4をシュート15に入れ、ローラ転造ダイス2の外周面へ落下供給し、最下位のねじ素材4をプッシャ16でローラ転造ダイス2の外周面と固定押さえ部材5との間へ押し入れていくと、ローラ転造ダイス2の回転によりねじ素材4を導入し、固定押さえ部材5の弾圧によって、ねじ素材4のねじ山はローラ転造ダイス2のねじ谷に噛合していき、ねじ素材4のねじ谷を埋めるように固定押さえ部材5が弾性変形する。
