る。 However, according to this method, if the welding line A0 is different, for example, the welding line A0 is A1 or A2
When a deviation occurs, in other words, as shown in Figure 3b, a coil with a plate width corresponding to the circumferential length of the ERW pipe to be manufactured is bent into a circle and the joint surfaces are continuously electrically welded. When welding, the joint surface may shift in the A1 or A2 direction. Joint surface is A 0
If it deviates from the point, the welding quality of the joint surface will deteriorate.At the same time, there are bead cutters 8 and 8' immediately behind the squeeze stand that remove beads E and E' that occur during welding, but these cutters cannot cut the beads and the product cannot be used. value decreases. Therefore, if this joint surface tries to deviate from the A 0 point, the joint surface can be maintained at the A 0 point by rotating the bottom roll 4 in the α 1 or α 2 direction, and high quality ERW pipes can be manufactured. I can do it. That is, the present invention provides a squeeze stand for ERW tube manufacturing equipment in which an ERW tube is supported by side rolls that can be moved left and right, and a top roll and a bottom roll that can be raised and lowered. This is a weld line correction device in a squeeze stand of electric resistance welded pipe manufacturing equipment, in which a swing lever is provided through the swing lever, and the bottom roll is moved in a direction perpendicular to the weld line by the swing lever.
以下本発明第２図、第３図に示す実施例装置に
より詳細に説明する。 The present invention will be explained in detail below using an embodiment of the apparatus shown in FIGS. 2 and 3.

造としている。 The side rolls 2, 2' are held by side roll chocks 5, 5', and are moved back and forth by a drive device built into a stand 6 on the rear surface. It supports the screw shafts 7, 7' and can move forward or backward depending on the diameter of the manufacturing tube. The top rolls 3, 3' are also constructed to be able to be raised and lowered by a drive device (not shown).

る。 The bottom roll 4 is rotatably fitted into a bearing box 11 through a shaft 10 having a metal 9 attached to its inner diameter. A part of the outer shape of the bearing box 11 is circular, and it comes in contact with the circular part of the bearing box guide 12 attached to the stand 6, so that it can rotate and move up and down. Also, there is a square hole 1 at the bottom of the bearing box.
5' and is fitted into the vertical shaft 13. A turning lever 14 is fitted into a square shaft part 15 of the vertical shaft 13, and is supported in the radial direction by bearings and metals 16 and 17.
This upper wedge 18 is supported by a screw female thread 20 installed in the lower wedge 19,
It can be raised and lowered by rotating a sprocket wheel 23 through a key 22 which is screwed onto a screw shaft 21. The screw shaft 21 is made of metal 2.
4. It is supported by a stand 6 through a bearing 25.
