Claims

[Scope of utility model registration request]

A high-frequency coil that heats the outer periphery of the processed part of the bent pipe, and an air blowing nozzle hole that is provided on the outer periphery of the outer end of the bent pipe so as to surround the pipe outer circumferential surface, and that has an air blowing nozzle hole that opens toward the pipe wall surface on the high-frequency coil side. A high-frequency tube bending machine characterized by having a cooling pipe consisting of a chamber and a water chamber on the opposite side of the air chamber and having a cooling water jet nozzle hole toward the tube wall surface.
