この発明は、鋼管の両端部に発生する曲りを矯正するた
めの装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an apparatus for correcting bends occurring at both ends of a steel pipe.
例えば、鍛接鋼管は、加熱炉で所定温度に加熱された帯
鋼を、成形ロール、鍛接ロールおよび絞りロールに順次
連続的に通し、成形ロールによって管状に成形し、鍛接
ロールによってその両エッジヲ鍛接し、絞りロールによ

断される。このようにして所定寸法に切断された鍛接鋼
管は、ローラコンベアによって冷却台に向けて移送され
、冷却台において冷却された後、次工程に送られる。For example, forge welded steel pipes are produced by passing a steel strip heated to a predetermined temperature in a heating furnace through a forming roll, a forge welding roll, and a drawing roll in sequence, forming it into a tubular shape with the forming roll, and then forge welding both edges of the steel with a forge welding roll. After the outer diameter is reduced by a squeezing roll, the material is cut into a predetermined size by a hot cutting machine. The forge-welded steel pipes thus cut into predetermined dimensions are transported by a roller conveyor to a cooling stand, where they are cooled and then sent to the next process.
ところで、熱間切断機により所定寸法に切断された高温
の鋼管は、ローラコンベア上音移送される間に冷却され
るが、このとき、管端部が管中央部に較べて速く冷却さ
れるため、管端部ｖｃ曲りが生じやすい。By the way, a high-temperature steel pipe cut to a predetermined size by a hot cutting machine is cooled while being transferred over a roller conveyor, but at this time, the ends of the pipe are cooled faster than the center of the pipe. , tube end VC is likely to be bent.

際に、管端が潰れたり、スパイラル状の疵が発生する等
の問題力・あった。Such bending at the end of the tube becomes more pronounced as the diameter of the tube becomes smaller, causing trouble during the transfer process until it is transferred to the subsequent straightening machine. There were problems such as the edges being crushed and spiral scratches occurring.

It is a sectional view taken along the line AA in the figure. As shown in the drawings, the apparatus 1 for straightening the bends in the ends of a steel pipe according to the present invention straightens the bends of a steel pipe 14 from above the ribs at both ends of the pipe 14, which moves at a constant speed in a direction perpendicular to the pipe axis while being cooled by a cooling stand clasp. An endless belt 2 that moves while being wound around sprockets 3, 4.5, which is arranged so as to press down, and a steel pipe 14 below the endless belt 2.
and a guide table 6 arranged so as to sandwich both ends of the guide table 6.

る。Since the device of this invention is not constructed as described above,
Both ends of the steel pipe 14, which moves at a constant speed while rotating on the cooling table, are pinched by the belt 2 and the guide table 6, which move in synchronization with the speed. Therefore, the bending that occurs at both ends of the steel pipe 14 is corrected by this squeezing force.
