Claims

[Scope of utility model registration request]

A device comprising a first forming tool and a second forming tool that is moved along the circumferential direction of the first forming tool, and bending a plurality of pipes at the same time by arranging them between the two forming tools and moving the second forming tool. and the first
and wide grooves arranged on the outer periphery of at least the first forming tool of the second forming tools so that the bottom surface is flat and the two side wall surfaces are in contact with each other on the bottom surface. A pipe bending device characterized in that pipe receiving portions are formed to face each other at substantially the same interval as the total dimension in the arrangement direction of the pipes.
