本発明はホースの外側又は中間層内に、金属製
又は合成樹脂製或いは両者の組合せから成るコイ
ルが巻装一体化されたコイル補強ホースの成形装
置に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a coil-reinforced hose in which a coil made of metal, synthetic resin, or a combination of both is wound and integrated on the outside or in the intermediate layer of the hose. Related to molding equipment.
（従来の技術）
今日、ホースは従来のゴム製ホースに対し軽量
で柔軟な合成樹脂製ホースの開発が種々行なわ
れ、特に軽量且つ柔軟なホースはコイル体の巻装
によつて薄肉を補強するようにしている。(Prior art) Today, various types of lightweight and flexible synthetic resin hoses have been developed in contrast to conventional rubber hoses.In particular, lightweight and flexible hoses are made by reinforcing thin walls by wrapping a coil body. That's what I do.
このコイル補強ホースの製造は、一般的にホー
ス（チユーブ）を押出し成形し、硬化したホース
の外周面に補強線材をコイル成形機によつて巻き
付けていくものでホースはコイルの巻き付け時の
張力によつて変形しないようにある程度の肉厚を
必要とされていた。 To manufacture this coil-reinforced hose, generally, a hose (tube) is extruded and a reinforcing wire is wrapped around the outer circumferential surface of the hardened hose using a coil-forming machine. A certain amount of wall thickness was required to prevent it from twisting and deforming.
しかも、上記した方法にあつては補強線材をホ
ースの外周に巻き付けていくため出来上つたコイ
ル補強ホースは補強線材の巻き方向に捩れ、流体
や気体を通した場合ホースが捩れ、作業しにくい
といつた不具合を有する。 Moreover, in the above method, since the reinforcing wire is wound around the outer circumference of the hose, the resulting coil-reinforced hose is twisted in the winding direction of the reinforcing wire, and when fluid or gas is passed through the hose, the hose becomes twisted and difficult to work with. It has some defects.

（コイル成形機）に送り込むためホース製造のラ
インが長くなり、装置の設置スペースも広くなる
等の不具合を有する。 In addition, since the reinforcing wire is directly wound around the hose, the hose is extruded from the extruder and then passed through a water tank to cool and harden, and the hose shape is fixed before it can be used with the coil winding device (coil winding device). Therefore, when forming a hose and continuously wrapping it with reinforcing wire, the hose (tube) extruded from the extrusion molding machine is passed through a cooling device such as a water tank to harden it and form it. After the hose is stabilized, it is sent to a coil winding device (coil forming machine), so the hose manufacturing line becomes long and the installation space for the device becomes large.

ブの外周面を圧着一体化することを特徴とする。(Means for Solving the Problems) The technical means of the present invention for solving the above problems is a tube extrusion molding machine in which an air blowing device is connected to piping so that air is blown into the extruded tube. The tips of the dies and mandrels arranged concentrically are expanded into a tapered shape with a predetermined distance from each other, and a wire-wrapping tube is formed on the outside of the die with a tapered tube that similarly expands at the tip. A rotating body is attached to be rotatable around the die, and a wire drum is attached to the outside of the cylindrical portion of the wire-wrapping tube, and the rotating body has a tapered outer peripheral surface of the wire-wrapping tube. The comb-shaped scraping claws that come into contact with the wire rod are integrally connected, and the wire is extruded from between the die and the mandrel onto the inner surface of a helical coil whose rotation is stopped and which is sequentially paid out from the maximum diameter part of the tapered tube in the wire winding tube. The outer peripheral surface of the tube in a molten state is crimped and integrated.

外径は、該テーパ筒の根本最小径部に巻き付けら
れた線材が解放された時、スプリングバツク（反
発）で拡開して巻き径が大きくなるが、その拡開
する径よりも大きい外径とする。 The outer diameter of the maximum diameter portion of the tapered tube in the above wire-wrapped tube is such that when the wire wound around the root minimum diameter portion of the tapered tube is released, it expands due to springback (repulsion) and the winding diameter increases. However, the outer diameter is larger than the expanding diameter.

材巻付筒のテーパ筒の根本部に巻回される。(Function) According to the above means, when the external force is removed, the reinforcing wire wound around the smallest diameter part of the tapered tube in the wire-wrapped tube expands due to spring back, but the diameter of the tapered tube is smaller than the expanded diameter. Since the outer diameter of the maximum diameter part of the tapered tube is large, the reinforcing wire is wrapped around the maximum diameter part of the tapered tube and its rotation is stopped.Therefore, the reinforcing wire pulled out from the drum installed on the rotating body is connected to the tapered tube of the wire-wrapped tube. It is wrapped around the root part of.

ーパ筒の最大径部側へ移動させて廻り、テーパ筒
及びダイスよりコイル状の補強線材が外れて軸方
向に送り出される。 Therefore, the rotating body rotates to pull out the reinforcing wire stored in the drum and wind it around the base of the tapered tube of the wire winding tube, and at the same time the scraping claw rotates to pull the reinforcing wire toward the maximum diameter side of the tapered tube. As the reinforcing wire is moved and rotated, the coiled reinforcing wire is detached from the tapered tube and die and sent out in the axial direction.

めチユーブはコイル内面に圧着一体化し、コイル
を巻装したホースが成形される。 At this time, the reinforcing wire of the coiled coil that is sent out tries to rotate in the circumferential direction by the ratio of the minimum diameter part and the maximum diameter part of the tapered tube, but the wire-wrapped tube rotates in the opposite direction to the rotating direction of the rotating body. Because of this, the coiled reinforcement wire is sent out in the axial direction without rotating in the circumferential direction, and moves in the axial direction riding on the outer periphery of the tube that is extruded from between the die and the mandrel. Since air is fed into this tube and it bulges out to have a circular cross section, the tube is crimped and integrated with the inner surface of the coil, and a hose with the coil wound thereon is formed.
