Claims

[Scope of Claim for Utility Model Registration] While clamping the pipe to be processed and rotating a rolling head that rotatably supports multiple round dies,
In a thread rolling machine for pipe materials, in which a pipe to be processed is placed in a rolling head and each round die is pressed against the outer circumference of the pipe to form a thread, each round die of the rolling head has a thread with a lead angle of zero. provided on the outer periphery, each round die is pivotally supported by the rolling head at an angle with respect to the pipe to be processed by the lead angle of the thread to be rolled; A thread rolling machine for pipe material, characterized in that the round dies are arranged sequentially shifted in the axial direction of the pipe to be processed by a fraction of the number of round dies.
