Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe sizing machines, in particular to a steel pipe sizing machine. Background Art

[0002] The sizing machine can make the outer diameter of the steel pipe reach the national standard. After being reheated in a stepping furnace and then sizing and rolling, a higher precision outer dimension is obtained. The hole type of the sizing roller can be adjusted individually or both rollers can be adjusted at the same time. It is the main tool for sizing. It is supported and rotated by the bearing in the sizing roller box, and ensures the correct position of the sizing roller in the frame.

[0003] For example, the Chinese patent with publication number CN217570177U proposes a seamless steel pipe sizing machine which is easy to maintain. The component drives the transmission shaft and the active bevel gear to rotate synchronously through a servo motor. The active bevel gear meshes with the first bevel gear and the second bevel gear, so that the first bevel gear drives the first threaded rod and the first threaded barrel to rotate relative to each other, and the second bevel gear drives the second threaded rod and the second threaded barrel to rotate relative to each other, and generates thread forces in opposite directions, and cooperates with the sliding of the limit barrel on the limit rod to push the connecting plate to move in the movable mouth, and the connecting plate drives the fixed plate to move synchronously to both sides of the sizing machine, so that the fixed block and the fixed groove are separated, which is convenient for disassembly of the sizing machine and maintenance, avoiding the traditional bolt fixing method, which is time-consuming and labor-intensive to disassemble and assemble. However, in this scheme, the steel pipe is not limited in the process of approaching the sizing machine, which is easy to cause the steel pipe to deviate during movement and affect the processing efficiency of the steel pipe. For this reason, we propose a steel pipe sizing machine. Utility Model Content
