[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 5 As shown, the purpose of this embodiment is to provide a rolling mill for rebar production, including a cooling pipe 101. One end of the cooling pipe 101 is fixedly connected to a connecting frame 102, and the other end of the connecting frame 102 is fixedly connected to a limiting ring 103. A scraper 104 is fixedly connected to the limiting ring 103 near the surface of the cooling pipe 101. A cooling unit is connected to the upper surface of the cooling pipe 101. A cooling box 105 is fixedly connected to the end of the cooling pipe 101 near the limiting ring 103. An air-cooling component is connected to the upper surface of the cooling box 105, and a water-cooling component is connected to the lower surface of the cooling box 105.

[0023] In this embodiment, during rolling, the rebar enters along the cooling pipe 101. After entering the cooling pipe 101, it is cooled by the air-cooling assembly. At the same time, during the conveying process, the scraper 104 on the limiting ring 103 cleans the iron oxide scale on its surface. When the rebar enters the cooling box 105, it is water-cooled and generates steam. The generated steam enters the air-cooling assembly along the gas delivery pipe 201. The turbine 204 compresses the steam to generate a strong airflow, which cools the rebar in the cooling pipe 101, thus achieving a cooling cycle.

[0024] In this embodiment, as Figure 1 - Figure 5 As shown, the air-cooled assembly includes an air supply pipe 201, with the other end of the air supply pipe 201 connected to a fan shroud 202. The lower surface of the fan shroud 202 is connected to a fixed cylinder 203. A turbine 204 is fixedly connected to the bottom surface of the fixed cylinder 203. A connecting pipe 205 is connected to the lower surface of the fixed cylinder 203. The other end of the connecting pipe 205 is connected to a wind box 206.

[0025] In this embodiment, the gas pipe 201 can collect the generated water vapor into the inside of the fan cover 202, and then form a higher air pressure through the expansion of the gas, converting heat energy into wind energy. The wind energy drives the turbine 204 to rotate, thereby cooling the threaded steel inside the cooling pipe 101.

[0026] In this embodiment, as Figure 1 - Figure 5As shown, the water cooling assembly includes a water supply pipe 301, one end of which is connected to the cooling box 105, and the other end is connected to a water pump 302. The input end of the water pump 302 is fixedly connected to a water tank 303.

[0027] In this embodiment, the water-cooled component achieves cooling through heat exchange with a cooling medium. During the cooling process, the cooling medium comes into contact with the rebar and is vaporized. The generated water vapor is collected by the air-cooled component for primary cooling. One end of the water pipe 301 is connected to a cooling box 105 for storing the cooling medium, and the other end is connected to a water pump 302 for pumping the medium.

[0028] In this embodiment, as Figure 1 - Figure 5 As shown, a guide plate 401 is connected to the water tank 303 near the water pump 302. The guide plate 401 is inclined and a filter plate 402 is fixedly connected to its upper surface. The filter plate 402 is inclined and fixedly connected to the cooling box 105.

[0029] In this embodiment, the guide plate 401 connected to the water tank 303 near the water pump 302 is used to feed the cooled medium. The filter plate 402 fixedly connected to the upper surface of the guide plate 401 can filter the iron oxide scale scraped by the scraper and prevent it from entering the water tank 303 along the guide plate 401.

[0030] In this embodiment, as Figure 1 - Figure 5 As shown, a baffle 501 is fixedly connected to the bottom surface of the cooling box 105. The baffle 501 is arc-shaped and has a through hole 502 at its constricted position.

[0031] In this embodiment, the baffle 501 fixedly connected to the bottom surface of the cooling box 105 is used to block the cooling medium. In addition, the baffle 501 is set to be arc-shaped and the through hole 502 at the constriction point can discharge the medium to rinse the filter plate 402.

[0032] In this embodiment, as Figure 1 - Figure 5 As shown, a support plate 601 is fixedly connected to the lower surface of the water tank 303. A workbench 602 and a servo motor 603 are fixedly connected to the upper surface of the support plate 601. An output gear 604 is fixedly connected to the output end of the servo motor 603. A transmission gear 605 meshes with the tooth root of the output gear 604. Rollers 606 are fixedly connected to the movable ends of both the output gear 604 and the transmission gear 605. Threaded grooves 607 are provided on the outer surface of the rollers 606.

[0033] In this embodiment, during rolling, the servo motor 603 drives the output gear 604 to rotate, which in turn drives the transmission gear 605 meshing with it to rotate. The rotation of the gear drives the corresponding roller 606 to rotate. When the roller 606 rotates, it realizes the rolling of the threaded steel. In some cases, the threaded groove 607 provided on the outer surface of the roller 606 can be adjusted according to the size of the threaded steel.

[0034] In summary, the working principle of this utility model is as follows:

[0035] During rolling, the rebar enters through cooling pipe 101. Upon entering, it is cooled by the air-cooling assembly. Simultaneously, during transport, the scraper 104 on the limiting ring 103 cleans the iron oxide scale from the rebar's surface. When the rebar enters the cooling box 105, it undergoes water cooling, generating steam. This steam travels along the gas supply pipe 201 into the air-cooling assembly. The turbine 204 compresses the steam, creating a strong airflow that cools the rebar inside the cooling pipe 101, achieving a cooling cycle. The gas supply pipe 201 collects the generated water vapor inside the fan shroud 202. The gas then expands to create higher pressure, converting heat energy into wind energy. This wind energy drives the turbine 204 to rotate, cooling the rebar inside the cooling pipe 101. The water-cooling assembly achieves cooling through heat exchange with a cooling medium. During cooling, the cooling medium comes into contact with the rebar and vaporizes. The generated water vapor is collected by the air-cooling assembly for primary cooling. The water supply pipe 3... A cooling box 105 connected at one end is used to store the cooling medium, and a water pump 302 connected at the other end can draw the medium. A guide plate 401 connected to the water tank 303 near the water pump 302 is used to discharge the cooled medium. A filter plate 402 fixedly connected to the upper surface of the guide plate 401 can filter the iron oxide scale scraped by the scraper and prevent it from entering the water tank 303 along the guide plate 401. A baffle 501 fixedly connected to the bottom surface of the cooling box 105 is used to block the cooling medium. In addition, the baffle 501 is set to be arc-shaped and has a through hole 502 at the constriction point to discharge the medium and rinse the filter plate 402. During rolling, the servo motor 603 drives the output gear 604 to rotate, and drives the transmission gear 605 meshing with it to rotate. The rotation of the gear drives the corresponding roller 606 to rotate. The roller 606 realizes the rolling of the threaded steel when rotating. In some cases, the threaded groove 607 provided on the outer surface of the roller 606 can be adjusted according to the size of the threaded steel.
