Description

Technical Field

[0001] The utility model relates to the technical field of rectangular steel pipe straightening, in particular to a rectangular steel pipe straightening machine. Background Art

[0002] Rectangular steel pipe is a steel pipe with a rectangular cross-section, usually made of hot-rolled or cold-rolled steel plates. Rectangular steel pipe is widely used in the fields of construction, machinery, bridges, etc. It can be used for supporting structures, building frames, conveying liquids or gases, etc. Since steel has good strength and durability, rectangular steel pipe can withstand large loads and pressures, and plays an important role in some engineering projects. During transportation or use, rectangular steel pipes may bend or partially deformed. In order to make the rectangular steel pipes work properly, they need to be straightened with a rectangular steel pipe straightener.

[0003] However, the rectangular steel pipe straightening machine currently used is not convenient for quickly adjusting the spacing between the rollers and the pressure rollers, which limits the straightening of rectangular steel pipes of different sizes. In addition, the surface of the rectangular steel pipe needs to be manually cleaned before straightening to avoid the appearance of indentations caused by impurities attached to the surface. However, manual cleaning is not only inefficient, but also increases the workload of workers, which is inconvenient. Utility Model Content

[0004] The utility model aims to provide a rectangular steel pipe straightening machine which is easy to adjust, suitable for rectangular steel pipes of different sizes and capable of automatic cleaning.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A rectangular steel pipe straightening machine comprises a frame, wherein five rollers and four pressure rollers are respectively installed inside the frame, the ends of the five rollers are connected by a pulley group A, and the ends of the four pressure rollers are connected by a pulley group B, and both sides of the upper surface of the frame are provided with a lifting mechanism capable of adjusting the height of the four pressure rollers, and the outer surface of the frame is provided with a driving mechanism capable of simultaneously driving the rollers and the pressure rollers located on one side to rotate in the opposite direction. A fixed plate is installed on the outer surface of the frame, and two slide bars are slidably installed on the upper surface of the fixed plate, and a bottom brush plate is installed on the top of the two slide bars, and two side brush plates are installed on the outer side of the bottom brush plate through a transverse adjustment mechanism, and the transverse adjustment mechanism can simultaneously drive the two side brush plates to move in the opposite direction. A top brush plate is commonly arranged on the outer side of the two side brush plates, and a longitudinal adjustment mechanism capable of adjusting the height of the top brush plate is arranged inside the side brush plates. A reciprocating mechanism capable of driving the slide bar to reciprocate is arranged on the upper surface of the fixed plate.

[0007] It can be seen that through the setting of the lifting mechanism, the height of the pressure roller can be conveniently adjusted, so that it can be suitable for rectangular steel pipes of different sizes. Through the setting of the bottom brush plate, the two side brush plates and the top brush plate, under the drive of the reciprocating motion mechanism, the four surfaces of the rectangular steel pipe can be cleaned, thereby avoiding the appearance of indentations caused by impurities attached to the surface and avoiding the inconvenience of manual cleaning. In addition, through the setting of the lateral adjustment mechanism and the longitudinal adjustment mechanism, the spacing between the two side brush plates and the height of the top brush plate can be adjusted respectively, so that rectangular steel pipes of different sizes can be cleaned, and it has a wide applicability.

[0008] Furthermore, the lifting mechanism includes four mounting grooves opened on the surface of the frame, and sliders are slidably installed inside the four mounting grooves, and the two ends of the pressure roller are rotatably connected to the sliders on both sides respectively, the upper surfaces of the four sliders are connected to guide rods A, and the ends of the four guide rods A are commonly installed with connecting plates A, and a hydraulic cylinder A is installed on the upper surface of the frame, and the end of the telescopic end of the hydraulic cylinder A is connected to the connecting plate A.

[0009] When the height of the pressure roller needs to be adjusted, the hydraulic cylinder A can be started, and the telescopic end of the hydraulic cylinder A drives the connecting plate A to rise and fall, and then the pressure roller can be driven to rise and fall through the connecting action of the guide rod A to achieve the purpose of adjusting its height.

[0010] Furthermore, the driving mechanism includes a motor A installed on the outer surface of the frame, the end of the output shaft of motor A is connected to a connecting shaft A, a bump is installed on the outer surface of the frame, the bottom of the bump is rotatably connected to a connecting shaft B, the ends of the rollers and the pressure rollers away from the pulley group A and the pulley group B are both installed with bevel gears A, the outer surfaces of the connecting shafts A and B are both installed with bevel gears B, and the bevel gears B are meshed with the bevel gears A, and the connecting shafts A and B are connected by a telescopic rod.

[0011] When the rectangular steel pipe is to be straightened, the motor A can be started, and the motor A drives the connecting shaft A to rotate, and drives the connecting shaft B to rotate through the connecting action of the telescopic rod, thereby driving the two bevel gears B to rotate at the same time. Due to the meshing relationship between the bevel gear B and the bevel gear A, the supporting roller and the pressure roller are driven to rotate in the opposite direction at the same time, so as to achieve the purpose of straightening the rectangular steel pipe. Moreover, due to the telescopicity of the telescopic rod, when the height of the pressure roller is adjusted, the driving action on the supporting roller and the pressure roller can still be guaranteed.

[0017] By starting motor B to drive the reciprocating screw to rotate, the connecting plate B can be driven to reciprocate. Through the connecting action of connecting plate B, the bottom brush plate, two side brush plates and top brush plate can be driven to reciprocate simultaneously to clean the four surfaces of the rectangular steel pipe.

[0018] Furthermore, five guide rods B are arranged on both sides of the frame, one end of the five guide rods B is installed with a guide wheel, and the other end of the five guide rods B is commonly installed with a connecting plate C. A hydraulic cylinder B is installed on the outer surface of the frame, and the end of the telescopic end of the hydraulic cylinder B is connected to the connecting plate C.

[0019] By setting the guide wheel, the two sides of the rectangular steel pipe can be limited to avoid the deviation of the rectangular steel pipe during the straightening process, which affects the straightening effect. When the hydraulic cylinder B is started, the guide wheel can be driven to move forward and backward, so rectangular steel pipes of different sizes can be limited.
