Abstract
本发明提供了一种超大口径螺旋焊管成型器，包括副4#外控辊和副7#外控辊，所述副4#外控辊设于4#外控辊和5#外控辊之间，所述副7#外控辊设于3‑4点钟方向，所述副4#外控辊和副7#外控辊分别连接有向心度调节装置一和向心度调节装置二，所述向心度调节装置一用于调节副4#外控辊的位置对钢管9点钟方向上下5°范围内进行支撑，所述向心度调节装置二用于调整副7#外控辊对钢管的向心度。本发明可以对超大口径钢管进行有效支撑，满足向心度要求，解决管径变大时钢管涨套趋势使得钢管向成型器外控辊之间的各个缝隙不断充盈和扩散的技术问题，使得成型钢管几何尺寸控制更加精确，减少了不合格产品的产生，增强成型器工艺能力。
