Description
【発明の詳細な説明】 本発明はフレキシブル管製造に関するものである。[Detailed description of the invention] FIELD OF THE INVENTION This invention relates to flexible tube manufacturing.
従来フレキシブル管は、金属管を金型に入れ、金属管内
部よりの圧力（液圧又はゴムバルジ等）により、金属管
に数ケ所から数１０ケ所金属管外壁より膨出させた後に
、金型な金属管長手方向にたたんで製造した。Conventionally, flexible tubes are made by putting a metal tube into a mold and using pressure from inside the metal tube (hydraulic pressure, rubber bulge, etc.) to bulge out from the outer wall of the metal tube at several to several dozen places. Manufactured by folding a metal tube in the longitudinal direction.
本発明は金属管内に芯棒を入れ、上下金型により金属管
外壁を数ケ所から数１０ケ所金属管外径より小さく絞り
、金属管外壁に凹部な設けた後？こ金型を金属管長手方
向にたたんで作る、フレキシブル管の製造方法である。In the present invention, a core rod is placed in a metal tube, the outer wall of the metal tube is squeezed at several places to several tens of places smaller than the outer diameter of the metal tube using upper and lower molds, and a recess is formed in the outer wall of the metal tube. This is a method for manufacturing flexible pipes in which a metal mold is folded in the longitudinal direction of the metal pipe.
本発明はこのような方法で製造する為、長い金属管のど
の部分にもきわめて容易に、フレキシブル管の凹凸を作
ることが出来る。Since the present invention is manufactured by such a method, irregularities of the flexible tube can be created extremely easily in any part of the long metal tube.
また金属管内に芯棒な入れない製造方法と、金属管内径
と同径の芯棒な入れ、金属管外径と同じ内径の金型で、
外壁を保持して製造する方法も考えられる。In addition, we use a manufacturing method that does not include a core rod inside the metal tube, a core rod that has the same diameter as the inner diameter of the metal tube, and a mold that has an inner diameter that is the same as the outer diameter of the metal tube.
A method of manufacturing by holding the outer wall is also considered.

ｌは金属管、２は芯棒、３は上金型、４は下金型。FIG. 1 is a vertical cross-sectional front view of the metal tube of the present invention with a core inserted and the mold separated. Figure 2 shows 1. with the mold aligned vertically. Vertical section front view. FIG. 3 is a vertical cross-sectional front view of the mold when it is folded in the horizontal direction. 1 is a metal tube, 2 is a core rod, 3 is an upper mold, and 4 is a lower mold.
