[0002] Angle steel, commonly known as angle iron, is a long steel strip with two sides perpendicular to each other. There are equal-leg angle steel and unequal-leg angle steel. The two sides of equal-leg angle steel are equal in width. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connectors between components. It is widely used in various building structures and engineering structures. Hot-rolled angle steel is prone to bending, tipping and deformation after cooling on the cooling bed, which makes it impossible for the angle steel to pass the cold shearing smoothly.

[0025] Specifically, through the output of the first motor 11, the main gear 12 on the left is driven to rotate, and this rotational motion is transmitted between the two main bevel gears 13 and the sub-bevel gear 14, so that the main gears 12 on both sides rotate at the same time, which ensures that the sub-gears 7 on the left and right sides will also rotate. At the same time, the fixed plate 10 is connected to the sub-gear 7 through the movable frame 8, so that while the sub-gear 7 rotates, a driving force can be applied to the fixed plate 10 through the movable frame 8, so that the position of the connecting shaft 18 and the second straightening roller 19 can be adjusted, and then the distance between the first straightening roller 17 and the second straightening roller 19 can be adjusted. By adjusting the distance between the first straightening roller 17 and the second straightening roller 19, it is easy to adapt to angle steels of different sizes without complicated mechanical adjustments or replacement of components of different specifications. This not only improves the efficiency of the device, but also greatly expands its scope of application.

[0026] Reference Figure 1 and Figure 4The guide assembly includes a guide rail 2, the outer wall of the guide rail 2 is fixedly connected to the inside of the support platform 1, the inside of the support platform 1 is rotatably connected to a guide wheel 3, and the inside of the support platform 1 is rotatably connected to a conveying roller 4; the outer wall of the support platform 1 is fixedly connected to a support plate 20, and the inside of the support plate 20 is fixedly connected to a brush 21; the outer wall of the support plate 20 is fixedly connected to a third motor 22, and the output end of the third motor 22 is fixedly connected to a worm 23; the inside of the support plate 20 is rotatably connected to a connecting rod 24, and the outer wall of the connecting rod 24 is fixedly connected to a worm gear 25, and the worm 23 is meshed with the worm gear 25; the outer wall of the connecting rod 24 is fixedly connected to a mounting seat 26, and the inside of the mounting seat 26 is fixedly connected to a fan 27; the outer wall of the support platform 1 is fixedly connected to a conveyor belt 28;

[0027] Specifically, the angle steel is placed on the guide rail 2 and cleaned by the brush 21 on the support plate 20. At the same time, the third motor 22 drives the worm 23 to rotate, and the worm 23 engages with the worm wheel 25, so that the worm wheel 25 starts to rotate. The connecting rod 24 is driven by the worm wheel 25 and starts to rotate, thereby adjusting the blowing direction of the fan 27. This allows the blowing direction of the fan 27 to be adjusted as needed to ensure sufficient cooling of the angle steel. At the same time, the conveyor belt 28 is responsible for transporting the debris generated when cleaning the surface of the angle steel to the designated position for cleaning. This process ensures the smooth progress of the entire straightening process and improves the practicability of the device, which not only improves production efficiency, but also ensures product quality, making the entire production process smoother and more efficient.

[0028] Working principle: When different angle steels need to be straightened, the output end of the first motor 11 drives the left main gear 12 to rotate, and then the two main bevel gears 13 and the auxiliary bevel gear 14 mesh with each other, so that the main gears 12 on both sides can rotate at the same time, thereby driving the auxiliary gears 7 on both sides to rotate, and then the fixed plate 10 and the auxiliary gear 7 are connected by the movable frame 8, so that the auxiliary gear 7 can push the fixed plate 10 through the movable frame 8 while rotating, and then the position of the connecting shaft 18 and the second straightening roller 19 can be adjusted, so that the distance between the first straightening roller 17 and the second straightening roller 19 can be adjusted, so as to adapt to different angle steels, thereby achieving straightening of different sizes. The effect of straightening the angle steels together improves the efficiency of the device and expands the scope of application of the device. When the surface of the angle steel needs to be cooled and cleaned, the angle steel is placed on the guide rail 2 so that it can be cleaned by the brush 21 when passing through the support plate 20. At the same time, the third motor 22 drives the worm 23 to rotate, and the worm 23 and the worm wheel 25 are meshed with each other, so that the worm wheel 25 can rotate together, thereby driving the connecting rod 24 to start rotating to adjust the blowing direction of the fan 27. The conveyor belt 28 can then transport and clean the fallen debris, thereby achieving the effect of cooling and cleaning the impurities and debris on the surface of the angle steel, improving the practicability of the device and ensuring the smooth progress of the straightening process.
