Abstract:
The present disclosure provides a method for molding a pipe body that can inexpensively mold a pipe body having a tapered portion radially outwardly projecting relative to a large-diameter portion. The method for molding a pipe body comprises: molding of a tubular body by bending an unfolded stock so as to wrap a core metal; and removal of the core metal from inside the tubular body. The core metal comprises a first core metal piece for molding a projecting portion of the tapered portion. During the molding of the tubular body, the first core metal piece at least partly abuts on an inner surface of the projecting portion of the tapered portion, and does not abut on an area of the inner surface of the large-diameter portion located in an opposite side of a central axis of the large-diameter portion from the projecting portion.

Claim (Index 1):
A method for molding a pipe body including a large-diameter portion and a tapered portion continuously extending from the large-diameter portion, the tapered portion being tapered from a side in a vicinity of the large-diameter portion toward an opposite side away from the large-diameter portion, the tapered portion including a projecting portion located at a portion of an outer circumference of the tapered portion, the projecting portion outwardly projecting in a radial direction of the large-diameter portion relative to an outer circumference of the large-diameter portion, the method comprising:\n forming of an unfolded stock by drawing a plate stock into a cylindrical body that is opened along a line parallel to a central axis of the cylindrical body; disposition of a core metal on a surface of the unfolded stock that corresponds to an inner surface of the pipe body; molding of a tubular body including the large-diameter portion and the tapered portion by bending the unfolded stock so as to wrap the core metal; and removal of the core metal from inside the tubular body, wherein the core metal comprises a first core metal piece for molding the projecting portion of the tapered portion, and wherein, during the molding of the tubular body, the first core metal piece at least partly abuts on an inner surface of the projecting portion of the tapered portion, and does not abut on an area of the inner surface of the large-diameter portion located in an opposite side of a central axis of the large-diameter portion from the projecting portion of the tapered portion.
