Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe production, in particular to a steel pipe forming device. Background Art

[0002] Steel pipe refers to a steel material with a hollow section whose length is much greater than its diameter or circumference. It is usually made by rolling a steel strip into a tube shape after passing through a steel pipe forming device, and then welding the steel strips together to form a steel pipe, and then trimming, cooling and cutting.

[0003] For example, a steel pipe forming device with the authorization announcement number "CN213763480U" can correct the steel pipe through a correction mechanism to prevent the problem of uneven surface during the steel pipe forming process, thereby improving the production quality of the steel pipe. However, when the steel pipe forming device processes the steel pipe through the correction mechanism, the two correction rollers rotate in the same direction when correcting the steel pipe, because the same gear drives the two correction rollers to rotate, so the two correction rollers rotate in the same direction, which causes the steel pipe to be subjected to reverse thrust and unable to pass through the correction mechanism, which reduces the working efficiency of the steel pipe forming device. At the same time, the position of the nozzle of the steel pipe forming device is fixed. When the size of the steel pipe is small, the nozzle is far away and cannot spray cooling water onto the surface of the steel pipe, which reduces the working quality of the steel pipe forming device.
