電力ケーブル（CVケーブル）のコアの溶接点直下を保護
するには、構造的に弱く、又溶接直下のステンレス管内
面の溶接ビード部が酸化されるという問題点があった。[Problems to be solved by the invention] However, in the conventional cable protection guide having a structure in which only one iron plate is provided with a curvature, the weight just below the welding point of the core of the power cable (CV cable), which has a bend and bend, is protected. However, there is a problem in that the weld bead portion on the inner surface of the stainless steel pipe immediately below the weld is oxidized due to its structural weakness.

An object of the present invention is to provide a cable manufacturing apparatus having a cable core protection guide, which has a function of completely protecting the power cable core immediately below the welding point and further preventing oxidation of the weld bead portion on the inner surface of the stainless pipe.

The hollow space is filled with an inert gas, and the inert gas is injected from the injection hole provided at the tip of the guide to prevent oxidation of the inner surface of the welded stainless steel pipe. The structure that had only the function of [2] has the function of preventing the oxidation of another welding point.

造装置によって達成される。That is, the above object of the present invention is to provide a cable manufacturing apparatus having a stainless steel welding device for rolling and welding a stainless steel strip on the outer circumference of a cable core, and a cable core protection guide installed below the welding point. The cable core protection guide has a bag-shaped structure having a curvature, and a supply port for supplying an inert gas from the outside through the bag-shaped void and a jet for injecting the inert gas toward the welding point of the stainless steel. This is achieved by an apparatus for manufacturing a cable characterized by forming holes.
本考案のケーブルコア保護ガイドが曲率を有する袋状

より構成されたものにして強度を高めると共に、後述の
袋状の空間に不活性ガスを通すための空隙を設けるため

くても不活性ガスを通す空間があればよい。尚袋状の構
造を作るためには一枚の材料を用いて形成させてもよい
し、二枚の鉄板の縁部を溶接させて形成させてもよい。The bag-like structure in which the cable core protection guide of the present invention has a curvature means that the cable core protection guide is made of a single iron plate having a conventional curvature, but is made up of a substantially double iron plate. This is to increase the strength and to provide a space for passing an inert gas in the bag-shaped space described later.The curvature should be close to the curvature of the stainless steel pipe, and the bag-shaped volume should be particularly limited. It is sufficient if there is a space through which an inert gas can pass, even if it is not a prepared gas. In order to form the bag-like structure, it may be formed by using one material, or may be formed by welding the edges of two iron plates.
本考案において、外部より該袋状の空隙の中を通して
不活性ガスを供給する供給口と、該不活性ガスを溶接点
に向って噴射する噴射孔は、袋状のケーブル保護ガイド
に直接供給口と噴射孔を有して不活性ガスを袋状空間を
通すことだけに限らず、不活性ガス供給管を供給口から
噴射孔に到る迄敷設してもよい。In the present invention, the supply port for supplying the inert gas from the outside through the bag-shaped void and the injection hole for injecting the inert gas toward the welding point are directly connected to the bag-shaped cable protection guide. The injection hole is not limited to pass the inert gas through the bag-shaped space, and an inert gas supply pipe may be laid from the supply port to the injection hole.
上記によって、ケーブルコア保護ガイドは機械的構造
強度は袋状構造によって充分に保たれ、又溶接の熱対策
も充分になり、更に不活性ガスを溶接点に噴射すること
により溶接点の酸化防止対策が出来更に溶接点下のケー
ブルコアに対する熱防止対策にもなる。Due to the above, the cable core protection guide has sufficient mechanical strength by the bag-shaped structure, sufficient heat countermeasures for welding, and measures to prevent oxidation at the welding point by injecting an inert gas at the welding point. In addition, it can also be used as a heat protection measure for the cable core below the welding point.
本考案において不活性ガスの噴射する噴射孔は溶接点
直下にあるだけに限らず、その他の点よりステンレス管
の溶接点に噴射しても同様な効果を得ることが出来る。In the present invention, the injection hole for injecting the inert gas is not limited to just under the welding point, but similar effects can be obtained by injecting into the welding point of the stainless pipe from other points.
