【考案の詳細な説明】
アルミOFケーブルにおいて、鉛工やアルミ溶
接を行なう場合、ケーブルコアに高温が伝わらな
いように、アルミのコルゲート管の内径を大きく
して、ケーブルコアとの間のすき間を大きくする
必要がある。[Detailed explanation of the idea] When performing lead work or aluminum welding on an aluminum OF cable, the inner diameter of the aluminum corrugated pipe is increased to prevent the high temperature from being transmitted to the cable core, and the gap between it and the cable core is increased. It needs to be bigger.
そのための装置、方法などは、従来からいろい
ろ提案されている（たとえば特公昭47−1511号公
報、実願昭54−144651号明細書など）。しかし、
それぞれに一長一短がある。 Various apparatuses, methods, etc. for this purpose have been proposed in the past (for example, Japanese Patent Publication No. 1511/1983, Specification of Japanese Utility Model Application No. 144651/1983, etc.). but,
Each has its advantages and disadvantages.
本案は、短時間に内径を広げることのできる装
置に関するものである。 The present invention relates to a device that can expand the inner diameter in a short time.
実施例
「第１図」の１０はケーブルコア、１２はコル
ゲート管である。Embodiment 10 in FIG. 1 is a cable core, and 12 is a corrugated pipe.
１４は押広げ金具。 14 is a push-out metal fitting.
全体として円筒形で（第２図）、その内径は、
ケーブルコア１０の外径よりわずかに大きく、ケ
ーブルコア１０にほぼ外接しながら前進後退でき
る。その外面の後端部（図命で右側）は円筒面１
４０をなし、前端部は、テーパ面１４２をなす。
したがつて壁面の断面（中心軸１４４含む）は、
くさび形である。 It is cylindrical as a whole (Fig. 2), and its inner diameter is
It is slightly larger than the outer diameter of the cable core 10, and can move forward and backward while almost circumscribing the cable core 10. The rear end of its outer surface (right side in the design) is the cylindrical surface 1
40, and the front end portion forms a tapered surface 142.
Therefore, the cross section of the wall surface (including the central axis 144) is
It is wedge-shaped.
１６はベースで、これに押広げ金具１４の後端
が固定される。 Reference numeral 16 denotes a base, to which the rear end of the push-out metal fitting 14 is fixed.
１８はアンカー金具。 18 is the anchor fitting.
二つ割りになつており、ボルト締め、コルゲー
ト管１２の波形を利用してその上に固定する。 It is divided into two pieces, and is fixed on top of the corrugated pipe 12 by tightening bolts and using the corrugated shape of the corrugated pipe 12.
２２は押込み手段。 22 is a pushing means.
たとえば４本の油圧シリンダからなり、押広げ
金具１４とアンカー金具１８との間に取付けられ
る。油圧シリンダの代わりに、ターンバツクルな
ども使用できる。 For example, it is composed of four hydraulic cylinders and is installed between the push-out metal fitting 14 and the anchor metal fitting 18. Instead of a hydraulic cylinder, a turnbuckle or the like can also be used.

る。Operation: Set the spreading fitting 14, anchor fitting 18, pushing means 22, etc. as shown in FIG. The four hydraulic cylinders are operated at a constant speed to push out the spreading metal fitting 14.
Move it in the direction of the arrow 24 and forcefully push it into the inside of the corrugated pipe 12. Then, the taper surface 142 expands the valley 122 of the corrugated pipe 12 all at once.
以上のようにして、短時間に、コルゲート管１
２の内径を大きくすることができる。 In the above manner, corrugated pipe 1 can be constructed in a short time.
The inner diameter of 2 can be increased.
