Specific Embodiments

[0023] The technical solutions of the present invention will be described clearly and completely hereinafter with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0025] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Refer to Figure 1 、 Figure 2 and Figure 3, A section steel straightening device provided by the present utility model, which includes a straightening machine body 1 and straightening rollers 2 arranged on the straightening machine body 1. There are multiple straightening rollers 2 and they are distributed in two rows on the straightening machine body; the upper and lower two rows of straightening rollers 2 cooperate to straighten the section steel.

[0027] Reference Figure 1 、 Figure 2 And Figure 3 , It also includes a cleaning component for cleaning the oxidation slag on the outer edge surface of the straightening roller 2. The cleaning component includes a slag scraping member 3 and a purging member 7. A slag scraping member 3 is arranged on one side of each straightening roller 2. The slag scraping member 3 includes a cleaning brush 31 pressed on the outer edge surface of the straightening roller 2, a fixing frame 32 arranged on the straightening machine body 1, and an adjusting rod 33 with its top detachably connected to the fixing frame 32. The cleaning brush 31 is installed at the bottom end of the adjusting rod 33; the number of cleaning brushes 31 is at least one. When one cleaning brush 31 is provided, the lower end surface of the cleaning brush 31 matches the arc of the straightening roller 2 and the outer diameter of the cleaning brush 31 along the axial direction of the straightening roller 2 is the same as the axial length of the straightening roller 2. When the cleaning brush 31 sweeps the outer edge surface of the straightening roller 2, it can be attached to the outer edge surface of the straightening roller 2, increasing the contact area with the straightening roller 2. When the straightening roller 2 rotates, there is a sliding friction between the cleaning brush 31 and the straightening roller 2, so as to remove the oxidation slag on the outer edge surface of the straightening roller 2 at one time. Among them, the number of cleaning brushes 31 can be selected according to the actual working requirements. In this example, the number of cleaning brushes 31 is two. The two cleaning brushes 31 are arranged along the axial direction of the straightening roller and are staggered. The sum of the outer diameters of the two cleaning brushes 31 along the axial direction of the straightening roller 2 is the same as the axial length of the straightening roller 2. With the cooperation of the two cleaning brushes 2, the oxidation slag on the outer edge surface of the straightening roller 2 can also be completely removed.

[0028] Reference Figure 1 、 Figure 2 And Figure 3 , An adjusting screw rod 4 is arranged at the top of the adjusting rod 33 and slides through the fixing frame 32. At least two locking nuts 5 are arranged on the adjusting screw rod 4. The at least two locking nuts 5 are respectively located on the upper and lower sides of the fixing frame 32 to fix the adjusting rod 33 on the fixing frame 32. When the cleaning brush 31 works for a long time, the bristles of the cleaning brush 31 are worn and cannot fit well on the outer edge surface of the straightening roller 2. At this time, the height of the adjusting rod 33 can be adjusted through the cooperation of the adjusting screw rod 4 and the fastening nut 5, so that the brush head of the cleaning brush 31 can better fit on the outer edge surface of the straightening roller 2, ensuring the normal operation of the slag scraping member 3, making full use of the cleaning brush 31, reducing the replacement times of the cleaning brush 31, and saving costs.

[0029] A compression spring 6 for pressing against the cleaning brush 31 is sleeved on the adjusting rod 33. When the locking nut 5 on the adjusting screw rod 4 becomes loose after the slag scraping member 3 has been working for a long time and cannot lock the adjusting rod 33, it is easy to cause the adjusting rod 33 to drive the cleaning brush 31 to move up and down. At this time, a downward pressure is applied to the cleaning brush 31 through the restoring force of the compression spring 6, so that the cleaning brush 31 can better press on the outer edge surface of the straightening roller 2, further improving the cleaning quality of the straightening roller 2 and avoiding the problem of oxidized slag being pressed into the surface of the section steel. The adjusting rod 33 is inclined, and the inclination direction of the adjusting rod 33 is consistent with the rotation direction of the straightening roller 2. Through the inclined setting, the cleaning brush 31 can better remove the oxidized slag on the outer edge surface of the straightening roller 2; when the straightening roller 2 rotates, there is an interaction force between it and the cleaning brush 31. By setting the adjusting rod inclined, the adjusting rod is not easy to deform.

[0030] Reference Figure 1 , Figure 2 and Figure 3 , the purging member 7 is used to purge the remaining oxidized slag to ensure the cleanliness of the outer edge surface of the straightening roller 2 and further prevent the oxidized slag from being pressed into the surface of the section steel. The purging member 7 includes a blowing pipeline 71 arranged on the straightening machine body 1 and a jet branch pipe 72 communicated with the blowing pipeline 71 for purging the oxidized slag on the outer edge surface of the straightening roller 2. The air outlet of the jet branch pipe 72 faces the straightening roller 2. A cleaning spray pipe 73 for purging the oxidized slag on the surface of the section steel is also arranged on the blowing pipeline 71. The purging member 7 with this structure is simple in structure and convenient to process and manufacture.

[0031] In summary, when straightening the section steel through this section steel straightening device, the cleaning brush 31 covers and presses on the outer edge surface of the straightening roller 2 with a large contact area. When cleaning the oxidized slag, the cleaning brush 31 and the straightening roller 2 are in sliding friction, and the oxidized slag can be well removed from the straightening roller 2, improving the oxidized slag removal effect; in addition, the slag scraping member 3 and the purging member 7 cooperate to further clean and remove the oxidized slag on the outer edge surface of the straightening roller 2, thus avoiding the problem of oxidized slag being pressed into the surface of the section steel.
