Abstract
One aspect of the present disclosure is a manufacturing device for a bent pipe by which the bent pipe is obtained by bending a double pipe. The manufacturing device for a bent pipe includes an inner core metal, an intermediate core metal, a bending mold, and a controller. The controller executes a first bending process, a second bending process, and a re-bending process. In the first bending process, a first pipe and a second pipe are bend in a first direction in a first area. In the second bending process, the first pipe and the second pipe are bent in a second direction in a second area. The second area has more distance from a coupling portion than the first area does. In the re-bending process, the second pipe is bent in the same direction as the second direction in the second area.
