Problems solved by technology
[0003] When the steel pipe is installed and used, it is sometimes necessary to bend the steel pipe. However, due to the high cost of special bending equipment, it is not purchased in normal use. When there is a lack of special bending equipment for manual bending, the bending effect is not good. very ideal

The invention relates to the technical field of steel tube processing equipment, in particular to a manual bending device for a steel tube. According to the manual bending device, the lower end of a base plate is connected with four supporting blocks distributed in a matrix mode, an L-shaped supporting plate and a flamethrower are connected to the upper end surface of the base plate, the upper endof the flamethrower is lower than the upper end surface of the L-shaped supporting plate, a limiting plate is arranged above the L-shaped supporting plate, and bolts are movably connected into two strip-shaped holes formed in the limiting plate in an inserted mode. The manual bending device has the advantages that the structure is simple, the manufacturing cost is low, when the steel tube is bent, one end of the steel tube is fixed, so that the phenomena that in the bending process, the position of the steel tube is deflected, the size deviation is caused, and the use of the steel tube is influenced can be avoided, the steel tube is heated firstly, and the labor is saved when the steel tube is bent; and the device is simple in structure and low in operation difficulty, a limiting device is arranged, and the manual bending device is suitable for steel tubes with different bent angles by utilizing the rotation of an arc-shaped plate on a center shaft.
Description
technical field [0001] The invention relates to the technical field of steel pipe processing equipment, in particular to a steel pipe manual bending device. Background technique [0002] A steel pipe is a steel material with a hollow section whose length is much greater than its diameter or circumference. Steel pipes can be used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers. Steel pipe is also a kind of economical steel, which is used to manufacture building structure grids, pillars and mechanical supports, which can reduce weight and save metal by 20-40%, and can realize factory-like mechanized construction. The use of steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of the protective layer, saving investment and maintenance costs. [0003] When the steel pipe is installed and used, it is sometimes necessary to bend the steel pipe. Howev...
