本考案は、例えば冷延鋼板のめつきラインや焼な1しラ

ラッシュバット溶接した後の溶接部ばり取りと超音波探
傷とを行なうばり取りと検査装置の改良に関する。[Detailed description of the invention] This invention is used in steel strip processing lines such as plating lines and annealing lines for cold-rolled steel sheets, for example, to remove burrs from welded areas after flash butt welding for joining steel strips. This invention relates to improvements in deburring and inspection equipment that performs ultrasonic flaw detection.
従来、冷延鋼板のめつきラインや焼な!しライン等の銅
帯処理ラインにあ・いては、第1図に示すように、前後
鋼帯の接合端を切断機Eで整斉して溶接機Aでフラッシ
ュバット溶接して接合した後、その溶接部をばり取り装
置Cに送りばり取りを行なう。Traditionally, cold-rolled steel plate plating lines and baking lines were used. In a copper strip processing line such as a steel strip line, as shown in Fig. 1, the joint ends of the front and rear steel strips are aligned with a cutting machine E, and are joined by flash butt welding with a welding machine A. The welded portion is sent to a deburring device C for deburring.
そして、さらに超音波探傷装置りにおいて溶接部の超音
波探傷を行ない溶接の良否を判断していた。Further, the welded portion is subjected to ultrasonic flaw detection using an ultrasonic flaw detection device to judge whether the weld is good or bad.
なか、溶接不良と判断された場合は、再び切断機E1で
後退した既溶接部を切断除去して上記の接合及び検査を
繰返すのである。If it is determined that the welding is defective, the welded part that has retreated is cut and removed again by the cutting machine E1, and the above-mentioned joining and inspection are repeated.
上記のごとく、従来の方法は溶接した後のはり取りと溶
接部検査を2工程で別個に行なうため長時間を要し、鋼
帯の処理ライン操業に影響するため、鋼帯アキュムレー
タ装置を大きくする等して時間的補償を行なっていた。As mentioned above, in the conventional method, deburring after welding and weld inspection are performed separately in two steps, which takes a long time and affects the operation of the steel strip processing line, so the steel strip accumulator device must be made larger. etc., to compensate for time.
本考案は、かかる欠点を除去するため、溶接後のぼり取
り装置と超音波探傷装置を共動的に作動するように構成
し、ばり取りと欠陥検査を1工程で行える装置を提案す
るものである。In order to eliminate such drawbacks, the present invention proposes a device in which a deburring device after welding and an ultrasonic flaw detection device are configured to work together, and can perform deburring and defect inspection in one process. .

行移動する斜角超音波探傷装置を並設したことを要旨と
する。That is, the present invention uses a device that uses ultrasonic flaw detection to inspect flash butt welds where copper strips are joined, and includes a clamp and a cutting tool for holding down the vicinity of the welded portion of the steel strip. The gist is that a deburring device that reciprocates and an oblique ultrasonic flaw detection device in which a probe moves in parallel with a delay with respect to the cutting tool of the deburring device are installed side by side.
以下、本考案の実施例を図面について説明する。Embodiments of the present invention will be described below with reference to the drawings.
ぼり取り装置Cは、第2図および第3図に示すように、
鋼帯Bの接合溶接部の前後近傍を上下より押え込み、か
つバイトラ案内するためのクランプ3と溶接部上に位置
し、機台上に固定されたシリンダ4のピストンロッド2
の先端に取す付けたバイト1からなり、シリンダ4の作
動により溶接線に沿って往復動する。As shown in FIGS. 2 and 3, the scraping device C is
A clamp 3 for holding down the front and rear vicinity of the joining weld of the steel strip B from above and below and guiding the bit roller, and a piston rod 2 of a cylinder 4 located above the weld and fixed on the machine base.
It consists of a cutting tool 1 attached to the tip of a cylinder 4, which reciprocates along the welding line by the operation of a cylinder 4.
又、斜角超音波探傷装置りは上記シリンダ4に並設シた
シリンダ7のピストンロッド6の先端に取り付けられる
。Further, an oblique ultrasonic flaw detector is attached to the tip of the piston rod 6 of the cylinder 7 which is arranged parallel to the cylinder 4.
本考案は斜角超音波探傷装置を用いるが、この装置は発
受振器と被検査物との間に液体を充填する必要がある。The present invention uses an oblique ultrasonic flaw detection device, but this device requires liquid to be filled between the oscillator and the object to be inspected.
ところがその探傷触子を高速摺動させる場合は接触媒体
液層が追従しがたいため空気層が介在しやすいので、か
かる欠点のない回転式探触子を用いる。However, when the flaw detection probe is slid at high speed, it is difficult for the contact medium liquid layer to follow the probe, and an air layer is likely to be present. Therefore, a rotary probe that does not have this drawback is used.
この回転式探触子5はゴム製タイヤの中に、その中心支
軸に吊支固定された振動子を設け、かつ水、油等の液体
を充填してなり、第3図に示すようにタイヤの接触点よ
り銅帯の溶接部へ超音波(板波)を発信し、かつ受信す
るのである。The rotary probe 5 has a vibrator suspended and fixed on the central shaft in a rubber tire, and is filled with liquid such as water or oil, as shown in FIG. Ultrasonic waves (plate waves) are transmitted and received from the contact point of the tire to the welded part of the copper strip.
そして、シリンダ7の作動によりタイヤは自転により回
転しながら移動するが、この際内部に吊支された発受振
器は鋼帯に近接した位置にあって回転しないのである。When the cylinder 7 operates, the tire rotates and moves, but at this time, the oscillator and receiver suspended inside the tire are located close to the steel strip and do not rotate.
上記ぼり取り装置Cのバイトと超音波探傷装置りの探触
子は平行して往復動できるようにするが、この際探触子
5はバイト1に対し一定の間隔を保ちながら遅れて移動
するよう構成する必要がある。The cutting tool of the deburring device C and the probe of the ultrasonic flaw detector are allowed to reciprocate in parallel, but at this time, the probe 5 moves behind the tooling tool 1 while maintaining a constant distance. You need to configure it like this.
そのため、第2図の実施例では、ばり取り装置Cのバイ
ト1と斜角超音波探傷装置りの探触子5の設置位置は互
いにずらして両者間に一定の間隔をもたせて、シリンダ
4及び7を同時に作動し探触子5が遅れて移動するよう
に設けた。Therefore, in the embodiment shown in FIG. 2, the installation positions of the cutting tool 1 of the deburring device C and the probe 5 of the oblique ultrasonic flaw detector are shifted from each other to maintain a constant distance between them. 7 are operated at the same time, and the probe 5 is moved with a delay.
したがって、ぼり取り装置Cのバイトに対し斜角超音波
探傷装置りの探触子が遅れて平行移動するなら他の手段
によることもできる。Therefore, if the probe of the oblique ultrasonic flaw detector moves parallel to the cutting tool of the deburring device C with a delay, other means may be used.

触子5により溶接部の欠陥検査を同時に行なうのである
。When the welded part of the joined steel strip reaches the deburring device C of the present invention, after stopping the movement of the steel strip, the steel strip is held down with the clamp 3 and clamped from above and below, and the cylinders 4 and 7 are operated simultaneously. While deburring is carried out using the cutting tool 1 of the deburring device C, defects in the welded portion are simultaneously inspected using the probe 5 of the oblique ultrasonic flaw detector, which moves in parallel after a delay.
なか、溶接部に欠陥を発見した際は、その溶接部を切断
機Eの位置1でもどして、溶接部を切除した後、再び溶
接及び検査を繰り返すのである。When a defect is found in a welded part, the welded part is returned to position 1 of the cutter E, the welded part is cut out, and the welding and inspection are repeated again.

処理ラインの作業性を著しく向上できる。As mentioned above, the present invention performs welding deburring and welding defect inspection using oblique ultrasonic flaw detection in one process, so there is no need for extra time for inspection as in the conventional method. The time required for this process can be shortened, and the workability of the copper strip processing line can be significantly improved.
