Claims (5)

原鋼管の両端をチャックして回転させながら出側を引くことにより軸線方向に移動させ、中間のロール装置によりテーパー状に絞り加工を行うテーパ鋼管の製造方法において、工程中の特定時間に入側の原鋼管に圧縮力を作用させることにより、原鋼管よりも肉厚の部分を持つテーパー鋼管を得ることを特徴とするテーパー鋼管の製造方法。 In the manufacturing method of tapered steel pipes, which are moved in the axial direction by pulling the outlet side while chucking and rotating both ends of the raw steel pipe, and drawing into a taper shape by an intermediate roll device, the inlet side is entered at a specific time during the process. A taper steel pipe having a thicker portion than the raw steel pipe is obtained by applying a compressive force to the original steel pipe. 原鋼管の出側と入側をそれぞれ台車に搭載されたチャック機構によりチャックさせ、入側端部をチャックした台車の移動速度を制御することにより入側の原鋼管に圧縮力を作用させる請求項１記載のテーパー鋼管の製造方法。 Claims in which the outlet side and the inlet side of the raw steel pipe are each chucked by a chuck mechanism mounted on the carriage, and a compression force is applied to the incoming raw steel pipe by controlling the moving speed of the carriage with the inlet end chucked. A method for producing a tapered steel pipe according to 1. 入側端部をチャックした台車の移動速度を該台車の追従移動速度よりも速くすることにより、原鋼管をロール装置に向かって押し込むようにして圧縮力を作用させることを特徴とする請求項２記載のテーパー鋼管の製造方法。3. The compressive force is applied by pushing the raw steel pipe toward the roll device by making the moving speed of the carriage chucked on the inlet side end faster than the following moving speed of the carriage. The manufacturing method of the taper steel pipe of description. 入側端部をチャックした台車の移動速度を原鋼管に作用する張力に基づいて制御することを特徴とする請求項２又は３記載のテーパー鋼管の製造方法。4. The method of manufacturing a tapered steel pipe according to claim 2, wherein the moving speed of the carriage chucked at the inlet end is controlled based on a tension acting on the raw steel pipe. ロール装置の入側に設けた加熱装置により原鋼管の加工部分を加熱することを特徴とする請求項１〜４の何れか１項に記載のテーパー鋼管の製造方法。The method for manufacturing a tapered steel pipe according to any one of claims 1 to 4, wherein a processed portion of the original steel pipe is heated by a heating device provided on the entry side of the roll device.
