Pipe bending processing apparatus and pipe bending processing method

摘要

A pipe bending processing apparatus includes a drawing and bending section for pressingly contacting a drawing and bending mold, a clamp mold with one end of a pipe P and performing drawing and bending processing, compression bending section for pressingly contacting a chuck with the other end of the pipe and performing compression bending processing, side bending section for pressingly contacting a wiper, and a side bending mold with the side of the pipe and performing side bending processing. The side bending mold provides a stopper 8 which advances and retracts from a pipe pressingly contact surface and engages with the other end of the pipe.
