Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe straightening, and more specifically, to a seamless pipe straightening mechanism. Background Art

[0002] A steel pipe made of a whole piece of metal with no seams on the surface is called a seamless steel pipe. According to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, jacking pipes, etc. According to the cross-sectional shape, seamless steel pipes are divided into round and special-shaped pipes. Special-shaped pipes have a variety of complex shapes such as square, oval, triangle, hexagon, melon seed, star, and winged pipes. The maximum diameter is 650mm and the minimum diameter is 0.3mm. According to different uses, there are thick-walled pipes and thin-walled pipes. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation. At present, when straightening steel pipes, some steel pipes are twisted to a large extent. During straightening, the twisted parts of the steel pipes will collide with the edge of the straightening device, thereby damaging the surface of the steel pipe and easily affecting the stability of the straightening of the steel pipe.
