Description

Technical Field

[0001] The utility model relates to the technical field of welded pipe processing, in particular to a stainless steel welded pipe weld leveling device. Background Art

[0002] Welded steel pipe, also known as welded pipe, is made by welding steel plates or strips that have been coiled and formed. It is typically made in lengths of 6 meters. Welded steel pipe offers a simple production process, high efficiency, a wide variety of specifications, and minimal equipment investment, but is generally weaker than seamless steel pipe.

[0003] Existing welded pipes often use leveling rollers to level the welds after welding during production and processing. Since the leveling rollers need to be set at the top, bottom and both sides of the welded pipe, it is necessary to adjust the leveling rollers in different positions one by one when leveling different welded pipes, which is inconvenient to operate. In addition, errors may occur when adjusting the leveling rollers in different directions and positions, which can easily lead to correction errors in the welded pipe. Utility Model Content

[0006] Preferably, one side of the bidirectional screw rod is fixedly connected to an adjusting disk, and the adjusting disk is designed as an anti-slip structure.

[0007] Preferably, the distance between the two first straightening wheels is equal to the distance between the two second straightening wheels.
