ものである。[Detailed Description of the Invention] When welding an unwelded tube body formed by a welding ring using a high-frequency induced current or the like, a seam that guides the V convergence point of the edge portion to the center of the welding roll is related to the welding device. It is something.
電縫管製造装置において、帯鋼をフォーミングにて成形
し、溶接ロールに至る間に帯鋼の偏肉。In the electric resistance welded pipe manufacturing equipment, the steel strip is formed by forming, and the thickness of the steel strip becomes uneven during the process of forming the steel strip to the welding roll.

しばしばあった。Side bending, uneven tightening of forming rolls, and other factors can cause a twisting phenomenon in the material called sealing. As a result, the V convergence point of the edge part deviates from the proper approach position and deviates from the center of the welding roll, causing defects in the butt shape, changes in the amount of offset, etc., and making it impossible to obtain a healthy quality of the welded part such as poor welding strength. There were often none.

2a。In order to solve this problem, conventionally, as shown in FIG.
The seam guide fin 12 is inserted and guided within the V convergence angle a of 1, and the seam guide 12 is guided. A method has been proposed in which the V convergence point 14 of the edge portion is guided to the center of the welding roll 15.15 by one roll 13. However, Figure 2 (a)
From (b), the seam guide fins 12 and the support rolls 13 are connected to the shaft 1 installed perpendicularly to the tube axis.

。Because it is pivoted to 13a, soumga 1 dofin 12
The support roll 13 can only be moved vertically and perpendicularly to the tube axis, and as a result, the torsion of the material can be adjusted.
This was mainly done by moving the seam guide fin in a direction perpendicular to the tube axis. Reference numerals 16 and 17 are a horizontal adjustment device and a vertical adjustment device of the seam guide device.

ことが可能である。Next, the operation of the seam guide device according to the above invention will be explained. The adjustment device 48 moves and adjusts the sliding plate 44 left and right, and the adjustment device 45 moves the holding plate 40 to the left and right.
slide in the vertical direction to pre-swage and center the seam guide device. Next, the fine adjustment device 36 expands and contracts the support rolls 32, 33, 33' to press the unwelded tube body 11 in a direction perpendicular to the tube axis to accurately center it. At this time, the unwelded tube body 11 is held in a predetermined shape by the support rolls 32 including the seam guide fins 31, but when a twisting phenomenon called rolling occurs in the raw steel strip, the convergence point of the edge part It will deviate from the proper entry position and deviate from the center of the welding roll, resulting in defective products such as poor butt shape. Therefore, in order to correct the twist, the unwelded tube body 11 is transferred to the support roll 32 including the seam guide fins 31 while maintaining the predetermined shape, and then transferred to the head 3 by the rotation device 41.
5 and rotates around the tube axis in the opposite direction to the twisting direction. In this case support roles 32, 33, 33
In the unwelded pipe body 11 surrounded by It is possible to guide the V convergence point to the center of the welding roll while maintaining the predetermined shape without causing damage or the like.

れる。In addition, for expanding and contracting the support roll when changing rolls due to size changes and roll polishing, if a scroll chuck, for example, is used as the head, expansion and contraction can always be performed around the tube axis, making it easy to adjust the centering. But what about the wear and tear on the support rolls? - Slight changes in the roll diameter can be adjusted using the vertical fine adjustment device attached to the roll holder.

などにおいて極めて有効である。As described above, if the seam guide device according to the present invention is used, when guiding the V-convergent part of the unwelded pipe body to the center of the welding roll, it is possible to avoid problems such as poor opening of the seam with respect to the pipe axis and pressing only one edge. It is possible to prevent edge damage or deformation of the tube before it enters the welding roll, and is extremely effective in reducing machine stoppages for these adjustments, improving workability, and improving quality.
