Description

Technical Field

[0001] This utility model relates to the field of hot rolling cooling technology, specifically a cooling device for hot rolled wire. Background Technology

[0002] In the production process of hot-rolled wire rod, it needs to be rolled in multiple stages. For example, after rough rolling, the billet needs to be cooled to 1000-1300℃ before further rolling. Therefore, precise cooling and temperature control of the wire rod are required in the diameter change range of rolling.

[0003] Common cooling equipment cools hot-rolled wire rods by spraying water, carrying away heat through the water flow. However, this method typically only involves the upper surface of the hot-rolled wire rod in contact with the water, easily leading to uneven temperature distribution in localized areas and affecting the rolling effect. Current solutions involve increasing the number of cooling nozzles to surround the hot-rolled wire rod. However, the arrangement of these nozzles is usually fixed, making it impossible to adjust their position according to the water spray pattern. This results in some water flows interfering with each other, reducing the cooling effect. Therefore, this paper was developed to address these issues through in-depth research.

[0017] 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.

[0018] Please see Figure 1-3 This utility model provides an implementation scheme: At present, the way to deal with uneven cooling of hot-rolled steel is to increase the number of cooling nozzles 8 so that the cooling nozzles 8 surround the hot-rolled wire. However, the arrangement of the cooling nozzles 8 is usually a fixed structure, and the position cannot be adjusted according to the water flow spray fan of the cooling nozzles 8, which leads to mutual interference of some water flows and a reduction in cooling effect.

[0019] To address the aforementioned issues, this application discloses a cooling device for hot-rolled wire rod, comprising a support frame 1. The support frame 1 is a rectangular frame structure that provides a stable support platform for the entire device. A pass seat 2 is installed on the top of the support frame 1. The pass seat 2 is separately connected to the support frame 1 to facilitate the assembly, disassembly, and maintenance of the device. A partially annular adjustment track 3 is provided on the pass seat 2 to precisely guide the movement path of the adjustment seat 4. Several adjustment seats 4 are installed on the adjustment track 3 for mounting nozzles 8 and enabling them to move flexibly along the track to adjust their positions.

[0020] A circulating cooling device is provided on the pass seat 2. The circulating cooling device includes a water supply pipe 5, which is installed on one side of the pass seat 2 to introduce cooling water into the system. A diverter seat 6 is provided on the pass seat 2 to receive the cooling water from the water supply pipe 5 and distribute it. Several diverter pipes 7 extend from the diverter seat 6 to deliver the distributed cooling water to each nozzle 8. A nozzle 8 is provided on the adjusting seat 4. The nozzle 8 faces the axis of the pass seat 2 to ensure that the cooling water can be accurately sprayed onto the surface of the hot-rolled wire for cooling. The nozzle 8 is connected to the diverter pipes 7 and receives the water flow delivered by the diverter pipes 7.

[0021] An adjusting gear ring 9 is provided on the adjusting track 3 as a fixed reference ring for adjusting the movement. An adjusting gear 12 is provided on the adjusting seat 4 and meshes with the adjusting gear ring 9. When the adjusting gear 12 rotates, the meshing action of the gear and the gear ring drives the entire adjusting seat 4 to slide circumferentially along the adjusting track 3, thereby changing the installation position of the nozzle 8. An output shaft 13 is axially connected to the adjusting gear 12. The output shaft 13 is movably mounted in the adjusting seat 4 and is used to transmit rotational power. An adjusting component 14 is movably mounted on the adjusting seat 4 and connected to the output shaft 13. By operating the adjusting component 14, the output shaft 13 and the adjusting gear 12 can be driven to rotate, thereby achieving precise control of the position of the nozzle 8.

[0022] As a preferred embodiment, at least two pairs of fixing holes are provided on both sides of the bottom of the base 2. Two pairs of tie bolts are installed in the two pairs of fixing holes to connect with the support frame 1. A through hole is opened in the center of the base 2. The tie bolts of a hot-rolled wire cooling device pass through the fixing holes to firmly fix the base 2 to the support frame 1, ensuring the overall stable and reliable operation of the device. At the same time, the central through hole provides a smooth passage for the hot-rolled wire.

[0023] As a preferred embodiment, furthermore, several pairs of connecting joints 10 are arranged side by side on both sides of the distribution seat 6. The connecting joints 10 are connected to the ends of the distribution pipes 7, and a main connector 11 is provided at the tail end of the distribution seat 6 to connect to the water supply pipe 5. The parallel arrangement of the connecting joints 10 in a cooling device for hot-rolled wire facilitates the quick connection and disassembly of the distribution pipes 7, simplifying pipeline maintenance. The main connector 11 enables efficient connection between the distribution seat 6 and the water supply pipe 5.

[0024] As a preferred option, the cross-section of the adjusting track 3 is T-shaped, and one side of the adjusting seat 4 is partially embedded in the adjusting track 3. This T-shaped track cross-section and the partially embedded adjusting seat 4 provide stable support and precise guidance for the adjusting seat 4, effectively preventing it from shaking or derailing during movement, and ensuring smooth and precise adjustment of the nozzle 8 position.

[0025] As a preferred embodiment, the adjustment assembly 14 further includes an adjustment knob 141, which is movably mounted on the adjustment seat 4. An adjustment worm gear 142 is connected to the bottom of the adjustment knob 141. An adjustment worm wheel 143 is coaxially arranged on one side of the adjustment gear 12. The adjustment worm wheel 143 meshes with the adjustment worm gear 142. When the adjustment knob 141 is rotated, the adjustment worm gear 142 rotates, and the adjustment worm gear 142 drives the meshing adjustment worm wheel 143 to rotate, which in turn drives the coaxial adjustment gear 12 to rotate. This worm gear transmission method provides deceleration and force amplification and self-locking functions, enabling the operator to make fine adjustments to the position of the nozzle 8 and ensure that the position is stable and does not deviate after adjustment.

[0026] Workflow Summary: A cooling device for hot-rolled wire rod continuously passes through the through hole in the center of the seat 2. Cooling water enters through the water supply pipe 5 and the main connector 11 of the distribution seat 6, and is distributed to each distribution pipe 7 through the connecting connector 10. Finally, it is sprayed onto the wire rod by the nozzles 8. The operator rotates the adjustment knob 141 on the specific adjustment seat 4 as needed. The knob drives the adjustment worm 142 to rotate, which in turn drives the adjustment worm wheel 143 to rotate. The adjustment worm wheel 143 is coaxial with the adjustment gear 12, thus driving the adjustment gear 12 to rotate. The rotating adjustment gear 12 meshes with the adjustment gear ring 9 fixed on the adjustment track 3, driving the entire adjustment seat 4 to slide circumferentially along the T-shaped section of the adjustment track 3. The adjustment seat 4 drives the nozzles 8 on it to move, thereby independently and precisely adjusting the circumferential position of each nozzle 8 relative to the wire rod. With slight radial changes, the water jet fan of each nozzle 8 is optimized, avoiding mutual interference of water flow, and achieving a uniform, efficient and customizable cooling effect. The self-locking characteristics of the worm wheel and worm ensure that the adjusted position is stable and reliable.
