摘要： PURPOSE:To smoothen preprocessing for O press forming and regular welding that follow U forming and to improve the quality of a steel tube by specifying a tool used for U press bending in manufacturing UOE steel tubes. CONSTITUTION:A tool 1 used for U press forming is so made so that the range of angle theta on the bottom 1a is 100-150 deg., and the radius of U-shaped steel plate sprung back after U press has a radius of curvature R that becomes the bending radius nearly corresponding to succeeding O press, and the radius of curvature on both sides 1b, 1b of the tool 1 that continue from the bottom 1a is made to a radius R1 which is smaller than the radius of curvature R of the bottom 1a by at least 30%.
摘要翻译：目的：为了平滑U型成形的预处理和U形成后的定期焊接，并通过在制造UOE钢管中指定用于U压弯的工具来提高钢管的质量。构成：用于U形冲压成形的工具1被制成使得底部1a上的角度θ的范围为100-150度，并且U型钢板的半径在U压制具有曲率半径之后弹回 R成为几乎对应于随后的O压机的弯曲半径，并且从底部1a继续的工具1的两侧1b，1b的曲率半径被制成半径R1，其小于半径R的半径R1 底部1a至少30％。

摘要： PURPOSE:To perform continuous tack welding at a high speed with good efficiency, by constituting an upper clamping body of a pair of light and left opening/closing type clamps which are separated at the center and opening successively the same when a welding head moves to approach the clamps. CONSTITUTION:A pipe P which is loaded in a machine frame 1 is so seamed that an open seam part P1 is positioned right above. A bolster 4 moves upward to lift the pipe P with a lower clamping body, thereby sandwiching the pipe between the same and an upper clamping body 6. When a welding head 13 moves to approach the position of the body 6, right and left opening/closing clamps 7, 8 open successively at the gap G that permits the movement and passage of the head 13 to permit continuous tack welding. The pipe P subjected to the tack welding is unloaded on conveyance rolls as the bolster 4 descends, and is discharged to the outside of the frame 1.
摘要翻译：目的：为了高效率地进行高速连续定位焊，通过构成一对光和左打开/闭合型夹具的上夹持体，它们在焊接头移动到中心时分开并相继开启接近夹子构成：装载在机架1中的管P如此被缝合，使开缝部P1位于正上方。枕头4向上移动以用下夹持体提升管P，从而将管夹在相同的上夹具6之间。当焊头13移动到接近主体6的位置时，右开和/ 关闭夹具7,8在间隙G处依次打开，允许头部13的移动和通过以允许连续定位焊接。经过定位焊接的管P随着垫板4的下降而在输送辊上卸载，并被排出到框架1的外部。
