Claims

[Scope of utility model registration request]

a rotatable bend roll whose other end of the pipe to be processed can be fixed by a clamp member and which has an arcuate portion according to the bending radius;
a pressure die disposed close to the bend roll and holding the other end of the pipe to be processed;
A pipe bending device comprising: a clamper that grips the other end of the pipe to be processed; and a boost cylinder connected to the clamper that pushes the other end of the pipe toward the bending side.
