Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel pipe rod processing, in particular to steel pipe rod straightening equipment. Background Art
[0002] Steel pipe rods have hollow sections, and their length is much greater than the diameter or circumference of steel. According to the cross-sectional shape, they are divided into round, square, rectangular and special-shaped steel pipes; according to the material, they are divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; according to the use, they are divided into steel pipes for pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, they are divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot rolling and cold rolling (drawing), and welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes. Steel pipes are not only used to transport fluids and powdered solids, exchange heat energy, and manufacture mechanical parts and containers, but they are also an economical steel material. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight, save 20% to 40% of metal, and realize factory-based mechanized construction. Using steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of protective coating, saving investment and maintenance costs.

The utility model solves the problem of difficult treatment of bulges and depressions of steel pipe rods in the prior art.
[0004] However, when the steel pipe straightening equipment is used to straighten the steel pipes, the internal support blocks cannot automatically follow the flattening device, so workers need to use means to push the internal support blocks to complete the straightening of the steel pipes. Moreover, since the hardness and strength of steel after cooling are higher than those in the hot state, the plasticity of steel is greatly reduced, making the straightening process very difficult. After straightening, the straightening accuracy of the steel pipe cannot be accurately measured. Utility Model Content
