AI Technical Summary
During the processing of straight seam welded pipes, the positions of the openings on both sides of the pipe do not correspond, resulting in a large amount of misalignment, which affects subsequent processing.
A misalignment correction device for straight seam welded pipe forming is adopted. The position of the correction plate is controlled by the rotation of the bidirectional lead screw driven by the first motor, and the vertical movement of the correction plate is adjusted by the cylinder. In conjunction with the rotation of the seam pressure roller driven by the second motor, pressure is applied to the welded pipe to achieve the alignment of the open edge of the welded pipe.
It effectively reduces the misalignment of the welded pipe opening, ensuring that both sides of the welded pipe are aligned, which facilitates subsequent processing.
