Description

Technical Field

[0001] The present application relates to the technical field of straightening machines, and particularly to a section steel straightening machine. Background Art

[0002] In the field of wind power equipment manufacturing, section steel, as a key structural material, its shape and dimensional accuracy directly affect the overall performance, stability and safety of wind power equipment. Key components such as wind turbine towers and blade support structures use a large amount of section steel materials, and these components often need to go through complex prefabrication and processing processes during manufacturing, among which the straightening link of section steel is particularly crucial.

[0003] Traditional section steel straightening methods mostly rely on manual operation or simple mechanical devices, which have problems such as low straightening efficiency, poor accuracy, and high labor intensity. Especially for the large-sized and high-requirement section steel required in the wind power field, traditional straightening methods often fail to meet production requirements. In addition, due to the differences in cross-sectional shape, size and material of different types of section steel, the requirements for straightening machines are also different, further increasing the difficulty and cost of straightening.

[0005] To achieve the above object, the present application provides the following technical solution: A section steel straightening machine includes a chassis, and two gantry frames are fixedly connected to the upper surface of the chassis. Two fixed shaft seats are installed at the inner bottom ends of the two gantry frames, and a fixed roller is rotatably connected between every two adjacent fixed shaft seats;

The additional calibration component (including a fixed plate, a cylinder, a transport seat and transport rollers) added at the middle end of the chassis provides additional support points for the profiled steel, effectively preventing the deformation problem of the profiled steel caused by being suspended in the middle during the movement process.

[0012] Furthermore, a plurality of stand feet are fixedly installed at the bottom of the chassis.

[0015] Through the above solution, through the setting of the threaded rod, the purpose of moving the moving shaft seat up and down can be achieved.

[0016] Furthermore, a turntable is fixedly connected to the top end of each threaded rod.

[0018] Furthermore, each adjusting plate is hinged to the gantry close to it, both ends of each adjusting shaft are rotatably connected to the adjusting plate close to it, and each clamping roller is fixedly connected to the adjusting shaft close to it.

[0019] Through the above solution, through the hinge connection between the adjusting plate and the gantry, the purpose of adjusting the spacing between the two clamping rollers can be achieved.

[0020] Furthermore, a limiting plate is fixedly connected to each side of the two gantries away from each other, and a limiting hole is formed on the outer surface of each limiting plate.

[0021] Through the above solution, through the setting of the limiting hole, an external bolt can be threadedly connected, and one end of it abuts against the adjusting plate, achieving the purpose of limiting the adjusting plate.

[0022] Further, a set of connection holes are provided on the upper surface of the fixed plate.

[0024] Further, the cylinder is fixedly inlaid with the fixed plate, the bottom end of the transport seat is fixedly connected to the output end of the cylinder, and the transport roller is rotatably connected to the inner side wall of the transport seat.

[0025] Through the above solution, the provision of the cylinder enables the height of the transport roller to be adjusted, thereby facilitating the support of the profiled steel.

[0026] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

Through the arrangement of the threaded rod 11, the purpose of moving the moving shaft seat 6 up and down can be achieved. A turntable 12 is fixedly connected to the top end of each threaded rod 11. Through the arrangement of the turntable 12, it is convenient for the user to rotate the threaded rod 11 to adjust the height of the moving roller 7.

[0037] A group of first correction components 8 are installed on one side of the two gantries 2 away from each other;

[0038] Please refer to Figure 1 , Figure 2 and Figure 3, each first correction component 8 of each group includes four adjusting plates 801, two adjusting shafts 802 and two clamping rollers 803. Each adjusting plate 801 is hinged to the gantry 2 close to it. Both ends of each adjusting shaft 802 are rotatably connected to the adjusting plate 801 close to it. Each clamping roller 803 is fixedly connected to the adjusting shaft 802 close to it. By the hinge connection between the adjusting plate 801 and the gantry 2, the purpose of adjusting the distance between the two clamping rollers 803 can be achieved. On the mutually remote surfaces of the two gantries 2, limiting plates 13 are fixedly connected. Limiting holes 14 are formed on the outer surface of each limiting plate 13. Through the arrangement of the limiting holes 14, an external bolt can be threadedly connected, and one end of it abuts against the adjusting plate 801, achieving the purpose of limiting the adjusting plate 801. A set of connection holes 15 are formed on the upper surface of the fixing plate 901. Through the arrangement of the connection holes 15, it is convenient for the user to connect with the chassis 1.

[0039] A second correction component 9 is provided at the middle end of the chassis 1.

[0040] Please refer to Figure 1 , Figure 2 and Figure 4 , the second correction component 9 includes a fixing plate 901, a cylinder 902, a transport seat 903 and transport rollers 904. The cylinder 902 is fixedly embedded with the fixing plate 901. The bottom end of the transport seat 903 is fixedly connected to the output end of the cylinder 902. The transport rollers 904 are rotatably connected to the inner side wall of the transport seat 903. Through the arrangement of the cylinder 902, the height of the transport rollers 904 can be adjusted, thereby facilitating the support of the profiled steel.

[0041] In a profiled steel straightening machine in this embodiment, by designing two pairs of adjustable straightening components including fixed rollers 4, movable rollers 7 and clamping rollers 803, the equipment realizes multi-point support and precise straightening of profiled steel. This design effectively prevents the deformation of profiled steel caused by the lack of support points during the straightening process, significantly improves the precision and effect of straightening, and ensures that the straightening profiled steel can meet the high-standard requirements of wind power equipment manufacturing. The movable rollers 7 and the clamping rollers 803 are both designed as adjustable structures. Among them, the height of the movable rollers 7 can be adjusted by a screw handwheel or a cylinder 902, while the distance between the clamping rollers 803 is adjusted by the hinge connection between the adjusting plate 801 and the gantry 2, enabling the equipment to easily meet the straightening requirements of profiled steel with different sizes and shapes, greatly enhancing the adaptability and flexibility of the equipment. The additional second correction component 9 provided at the middle end of the chassis 1 includes a fixing plate 901, a cylinder 902, a transport seat 903 and transport rollers 904, providing additional support points for the profiled steel and effectively preventing the deformation problem of the profiled steel caused by being suspended in the middle during the movement.

[0042] The working principle of the above embodiments is as follows: First, the profiled steel is placed between the fixed roller 4 and the moving roller 7 on the chassis 1. By rotating the turntable 12 at the top of the gantry 2, the threaded rod 11 drives the moving shaft seat 6 to slide up and down along the guide rail 5, thereby adjusting the height of the moving roller 7 to adapt to profiled steel of different thicknesses. This step ensures that the profiled steel can be stably supported when initially entering the calibration area. Subsequently, the profiled steel continues to move forward and enters the area of the first correction assembly 8. Four adjusting plates 801 are hinged around the gantry 2. By adjusting the angles of the adjusting plates 801, the distance between the two clamping rollers 803 can be adjusted to clamp and slightly correct the lateral bending of the profiled steel. During this process, the adjusting plates 801 are limited by the limit holes 14 and external bolts on the limit plate 13 to ensure the accuracy and stability of the adjustment. During the continuous movement of the profiled steel, the second correction assembly 9 in the middle of the chassis 1 starts to function. The cylinder 902 drives the transport seat 903 to move up and down, thereby adjusting the height of the transport roller 904 to adapt to the support requirements of the profiled steel at different positions. The transport roller 904 not only supports the profiled steel but also helps it pass through the entire calibration process smoothly, preventing deformation caused by suspension in the middle. Finally, through the precise calibration of the two pairs of correction assemblies, the bending, torsion and other deformations of the profiled steel are effectively improved, reaching the required shape and dimensional accuracy. The entire calibration process has a high degree of automation and is easy to operate, meeting the high standards for the calibration of profiled steel in the wind power field.
