Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thin-walled steel pipe shaping, in particular to a thin-walled steel pipe shaping tool. Background Art
[0002] Thin-walled steel pipe refers to a steel pipe with a ratio of outer diameter to wall thickness greater than 20. During processing or transportation, thin-walled steel pipes may be dented after being hit due to their small wall thickness, and a shaping tool is needed to repair surface defects.
[0003] The Chinese patent with the announcement number CN219745887U discloses a thin-walled steel pipe shaping tool, which includes a base, a support seat is fixedly installed at one end of the base, a clamping member for clamping the steel pipe is rotatably installed on one side of the support seat, a slide groove is provided on the top of the base away from the support seat, a transverse screw is rotatably installed in the slide groove, a second driving member for driving the transverse screw to rotate is installed on the base, a moving seat is threadedly connected on the transverse screw, a vertical screw is rotatably installed inside the moving seat, a lifting seat is threadedly connected on the vertical screw, and a shaping rod is fixedly connected on the side of the lifting seat close to the support seat. This application can realize the shaping of thin-walled steel pipes of different specifications through the cooperation of the first driving member, the second driving member, the moving seat, the lifting seat and the shaping rod, and has stronger adaptability.
[0004] With regard to the above-mentioned related technologies, in the prior art, the staff first uses a clamping piece to clamp the thin-walled steel pipe, and then uses the cooperation of a transverse screw and a movable seat to drive the shaping column to move, so as to extrude the thin-walled steel pipe and achieve the effect of shaping the thin-walled steel pipe. However, the clamping piece clamps one end of the thin-walled steel pipe, and the other end is in a vacant state. The shaping rod moves inside the thin-walled steel pipe and fits the inner wall of the thin-walled steel pipe. Since the thin-walled steel pipe has a certain length, the defect at the vacant end of the thin-walled steel pipe is subjected to the squeezing force, and there is an avoidance phenomenon. The longer the length of the thin-walled steel pipe, the more obvious the avoidance phenomenon is, resulting in the inability to repair the defects of the thin-walled steel pipe normally. Therefore, the shaping tooling of the prior art is only suitable for the shaping of thin-walled steel pipes with a shorter length, which reduces the applicability of the thin-walled steel pipe shaping tooling.
