【考案の詳細な説明】
本考案は、1個の固定電極の前後に隣接して設けられた
両移動電極のいずれか一方の移動電極と該固定電極とが
1組として任意に溶接機として選択使用できる銅帯連続
処理ラインにおけるフラッシュバッド・ダブル溶接機の
構造に関する。[Detailed Description of the Invention] In the present invention, one of the two movable electrodes provided adjacent to the front and rear of one fixed electrode and the fixed electrode are arbitrarily selected as a pair in a welding machine. This article relates to the structure of a flashpad double welding machine that can be used in a continuous copper strip processing line.
従来、帯鋼すなわち銅帯を連続製造ラインにおいて製造
するとき、その長軸方向の寸法を増大延長するために、
フラッシュバット溶接機が使用されている。Conventionally, when steel strips, that is, copper strips, are manufactured on a continuous production line, in order to increase and extend the longitudinal dimension of the steel strips,
A flash butt welder is used.
フラッシュバット溶接機は、この場合被溶接材料(鋼帯
等)をクランプ(把持)した固定電極ならびに移動電極
がちょうど固定鋼帯と移動鋼帯とが溶接位置で突合せで
きる位置で対向し溶接できるように、各1個づつの固定
電極と移動電極とが対向して1組となっている。In this case, the flash butt welding machine uses a fixed electrode that clamps (grips) the material to be welded (steel strip, etc.) and a movable electrode that face each other at a position where the fixed steel strip and movable steel strip can butt against each other at the welding position so that welding can be performed. A pair of fixed electrodes and a moving electrode are arranged facing each other.
これら固定電極は固定台上に固定され、また、移動電極
はフラッシュおよびアップセットできるように、移動台
と共に固定電極に接近離間できる。The fixed electrodes are fixed on a fixed platform, and the moving electrodes can be moved toward and away from the fixed electrodes with the moving platform for flushing and upset.
移動台は慣用の流体シリンダに連結されている。The carriage is connected to a conventional fluid cylinder.
このように従来の1個の固定極と1個の移動極とで1組
の溶接機を構威している銅帯連続処理フラッシュバット
溶接機では、高出力の電流により短時間で溶接できる長
所がその特色として認められ、その使用は広く常用され
ていた。In this way, the conventional flash butt welding machine for continuous processing of copper strips, which consists of one set of welding machines with one fixed pole and one moving pole, has the advantage of being able to weld in a short time with high output current. was recognized as its characteristic, and its use was widely used.
しかし、この従来のフラッシュバット溶接機は1組の対
向電極の対向面内面が火花の付着と強圧による変形のた
めに劣化し、溶接不良を発生することが多かった。However, in this conventional flash butt welding machine, the inner surfaces of opposing surfaces of a pair of opposing electrodes deteriorate due to adhesion of sparks and deformation due to strong pressure, often resulting in defective welding.
このため両電極とも同時に取替える必要があり、たとい
固定電極が使用できても移動電極が不良となれば同時機
に両電極を共に取替える必要があり、この電極取替には
長時間を必要とするため鋼帯製造ラインの稼動時間は、
このため大きく減少され鋼帯製造上の大きなマイナズ要
素となっていた。For this reason, both electrodes must be replaced at the same time, and even if the fixed electrode can be used, if the movable electrode becomes defective, both electrodes must be replaced at the same time, and this electrode replacement takes a long time. Therefore, the operating time of the steel strip production line is
For this reason, the amount was greatly reduced and became a major negative factor in the production of steel strips.
本考案者は、これら従来の欠点のあるプラッシュバット
溶接機の改善のため種々研究の結果、本考案のフラッシ
ュバット・ダブル溶接機を見出し、上記の欠点の改善に
成功した。As a result of various studies aimed at improving these conventional plush butt welding machines with drawbacks, the present inventor discovered the flash butt double welding machine of the present invention, and succeeded in improving the above drawbacks.
本考案においては、固定電極の両側に移動電極を設けて
、いままで使用していた固定・移動の両電極の対向電極
が前述のように火花付着やアップセット時の強圧で電極
面が荒れて使用不能状態になったとしても、固定電極の
その時まで使用していなかった反対側の電極面と、この
反対側の固定電極と対向する新移動電極とで1組のフラ
ッシュバット溶接機を構威し、はとんどあらたに手を加
えることなく位置を移すのみで使用可能としたものであ
る。In this invention, movable electrodes are provided on both sides of the fixed electrode, and as mentioned above, the opposing electrodes of both the fixed and movable electrodes used in the past have roughened electrode surfaces due to spark adhesion and strong pressure during upset. Even if it becomes unusable, one set of flash butt welding machine can be constructed using the opposite side of the fixed electrode that had not been used until then and a new movable electrode facing the fixed electrode on the opposite side. However, it can be used simply by relocating it without making any additional changes.
本考案の実施の一態様を図の銅帯連続処理ラインにおけ

したがって、各移動台車9を固定電極6の固定台11の
方向へ接近せしめることができる。Therefore, each movable cart 9 can be made to approach the fixed base 11 of the fixed electrode 6.
このようにして、鋼帯7の端面は互いに突き合わされる
ことができる。In this way, the end faces of the steel strips 7 can be butted against each other.
本考案によれば、当初は移動電極5と固定電極6とを使

すなわち、予備の移動電極5aのクランプ機構8゜を開
放状態に保持し、鋼帯が搬送ライン上を自由に通過でき

多数回の溶接によって両電極の電極端面51および61
が消耗・荒廃した場合には、いままで使用していた移動
電極5の使用状態を解除し、予備の移動電極5aを前述
と同様に使用する。The electrode end surfaces 51 and 61 of both electrodes are welded many times.
When the movable electrode 5 is worn out or deteriorated, the previously used movable electrode 5 is released from use, and the spare movable electrode 5a is used in the same manner as described above.
このときの対向電極面はまだ新しい状態であるので、い
ままでと同様の溶接を十分に行うことが可能である。Since the counter electrode surface at this time is still in a new state, it is possible to sufficiently perform the same welding as before.
このようにして、本考案によれば銅帯製造工程の中断な
