Claims

[Scope of utility model registration request]

After the tip of the tube is fixed in a bending die with a clamp die, the tube is bent by rotating the bending die and restraining the rear part of the tube with a pressure die so that it can slide in the axial direction but cannot move laterally. 1. An apparatus for bending a pipe, characterized in that an auxiliary mold for closely pressing the bent portion of the pipe is disposed adjacent to the pressure mold.
