接する方法などがある。The UOEO tube method is widely used in the production of large diameter steel pipes. In the UOEO pipe method, it goes through the well-known steps of E-pressing the material, U-pressing, O-pressing, tack welding, main welding, and pipe expansion. Tack welding is for aligning the seam part and performing temporary welding before the actual welding, and as a method for doing so, in order to prevent the OF shown in Fig. 1 and the gap GA shown in Fig. 2, There is a method of inserting the raw pipe into the cage roll and welding the full length plate with a welding machine fixed on the exit side of the cage roll while aligning the 7-mum part, or tightening the entire length of the raw pipe with a press or a band ramp. There is a method of tack welding intermittently using multiple welding machines arranged along the length of the tube axis.

の点で問題がある。However, with either method, it is difficult to eliminate seam gaps and especially offsets, and adjustments may have to be made after the fact. Furthermore, even if the offset amount is reduced within the specified range, welding defects may occur during actual welding. Furthermore, between 0 breath forming and actual welding, temporary 1ζ
Since a welding process is added, there are problems in terms of efficiency and installation (Mt space).
本発明は、前記従来の問題点を解決し、正確に仮付が可

がある。In the 0 press, both end surfaces of the O tube are in a state where they are butted at the exact position, but when the O tube is carried out from the 0 press,
Offset and gear up occur at the butt part. Therefore, the focus of the present invention is that if the tack attachment is performed in an O-press which is originally used for accurate butting, accurate tack attachment can be performed without offset or gaps.
以下本発明を第13図〜第10図に示す具体例によって
説明する。The present invention will be explained below using specific examples shown in FIGS. 13 to 10.

U管P′搬入のための位置決めとしている。That is, a pedestal 12 is fixed to the closing stand 8, and a boom 13 having a downward U-shaped cross section, for example, extends from the pedestal 12 into the O-pipe P. ] 4 is attached to the closing stand 8 fL ft , U O of the pipe P ′
A lower support roll 15 for carrying into the press is a side roll attached in the same way.
The support body 16 is pivotally attached to the stand 8 with a vertical pivot 17, and is rotated around the pivot 17 by the operation of a cylinder or the like (not shown) depending on the shape of the U-tube P'. 'This is positioning for transport.

出器28が一体的に設けられている。On the other hand, a long welding cart 18 rides on the boom 13 via running wheels 19 and positioning/running wheels 20. On the welding cart 18, a plurality of welding machines 21, 21, 21, 21, etc., six in the illustrated example, are arranged at equal intervals in the longitudinal direction. The details of each welding machine 21 are as shown in FIG.
Welding the dolly 1 to the fitting part 22a at the bottom of the support 22
The output screw shaft 23a of the lifting motor 23 fixed to the welding machine 2
1 is a fitting block 23a that can be raised and lowered 024
It is a guide cylinder for Further, a horizontal movement motor 25 is fixed to the support 22, and its output screw shaft 25a is connected to the support 22.
2, and this output screw IJ 25
A support block 26 is screwed to a, and as a result,
The support block 26 is moved horizontally by the rotation of the horizontal movement motor 25. A welding torch 27 is attached to the support block 26.
, its accessory equipment, and a seam portion (butt portion) detector 28 are integrally provided.

水平位置を定める構成とさ扛ている。In this way, the cauterizing machine 21 moves up and down depending on the diameter of the target O-pipe P to maintain the optimum distance from the seam, and the seam detector 28 detects the seam of the O-pipe P, and the welding torch It is said that the structure determines the horizontal position of 27.

、その先端が架台12の片持ちのみでは不安定である。On the other hand, in order to temporarily weld the entire length of the O-pipe P, welding cart 1
8 is horizontally movable and is attached to the boom 13. As a means for this purpose, a forward-reverse feed screw shaft 31 connected to an output shaft of a horizontal movement motor 30 fixed to the boom 13 is screwed onto a bracket 29 suspended downward from the welding cart 18. The length of this screw shaft 3 is determined by the arrangement pitch (in the axial direction) of the welding machine 21. Further, since the length of the boom 13 varies depending on the length of the zero pipe P, it is unstable if the tip of the boom 13 is only a cantilever of the pedestal 12.
そこで、ブーム13の先端部に、回転自在の支持足32

。Therefore, a rotatable support leg 32 is attached to the tip of the boom 13.
and an operating cylinder 33 for operating this. The cylinder rod of the operation cylinder 33 is connected to the support leg 3
It is connected to a lever 34 that is integrated with the support shaft of No. 2.

仮伺工程を詳ることなく、本溶接工程へ送る。In the production system configured in this manner, the boom 13, welding cart 18, and each welding machine 21 are placed on standby in advance in the zero press, as shown in FIG. Next, the U-pipe P' is carried into the zero press through the closing stand 8, and O-forming begins. When the process starts, the horizontal movement motor 30 is started, and each welding machine 21 is moved along the seam portion by the pitch to attach the full length plate. After completing this tacking and O-pressing, open the upper and lower dies 6.7 and take out the O-tube.
The product is sent to the main welding process without knowing the preliminary inspection process in detail.
ところで、もし溶接機1台で全長を仮イ」溶接しようと
すれば、溶接機にO管より長い長尺のネジ軸を直接螺合
して送るようにすればよい。By the way, if you want to temporarily weld the entire length with one welding machine, you can directly thread a long screw shaft that is longer than the O-tube into the welding machine and feed it.
この場合、溶接機に車輪を設け、溶接台車を不要とする
。しかし、1台の溶接機で行う場合、溶接時間が長くな
るので、能率性の点で不イ′すである。なお、全長板伺
でなく、断続仮付も勿論可能である。In this case, the welding machine is provided with wheels, eliminating the need for a welding cart. However, if one welding machine is used, the welding time will be long, which is disadvantageous in terms of efficiency. In addition, it is of course possible to use intermittent temporary attachment instead of full-length planking.
仮付溶接法としては、電子ビーム、レーダー、プラズマ
、TIG、MIG′4シーム部に対する上向き溶接が可
能な任意の@接法が適用できる。As the tack welding method, electron beam, radar, plasma, TIG, MIG'4 Any @ welding method capable of upward welding to the seam portion can be applied.
また溶接電源、駆動部の動力源およびイナートガス等は
Oプレスの外部に設けておくのがよい。Further, it is preferable to provide a welding power source, a power source for the driving section, an inert gas, etc. outside the O-press.

とができ、設備スペースの低減にも効果がある0As mentioned above, since the present invention performs tack welding in an O-press, it is possible to reliably perform tack welding in a regular manner without offsets and gaps. Since the 0 pipe after tacking can be directly used for main welding, it is possible to eliminate the setup time for carrying it into and out of the tacking process, which is a separate process as in conventional methods, all at once.
