[0033] Related technologies In the cold rolling process, temperature control is crucial. The uniformity of temperature distribution will directly affect the strip shape, and the temperature has an important impact on the surface quality of the strip. Therefore, the unit must have temperature regulation functions, such as fine segmented cooling of the rolls and induction heating of the working rolls on the edge of the line. Among them, one is a cooling system arranged between the racks, which has both temperature regulation and belt threading functions, and can effectively control the temperature. The cooling system is divided into an upper spray table and a lower spray table. When threading the belt, the lower spray table is used as a guide plate; during rolling, the upper and lower spray tables spray cooling lubricating oil, and the strip passes through them to achieve the cooling purpose; however, the overall operation is relatively bulky and not convenient and flexible enough. Secondly, another cooling system has only one row of nozzles. For strips of different widths, all nozzles will spray together. When the strip is a narrow strip, the nozzles distributed on both sides of the strip cannot spray the strip, which causes a waste of flow, which not only increases the cost, but also may have an adverse impact on the production environment, and reduces the cooling effect of the strip, thereby affecting the production quality of the strip.

[0034] In view of the problems existing in the above-mentioned related technologies, this embodiment provides a cooling system.

[0035] like Figures 1 to 4 As shown, a cooling system provided by an embodiment of the present invention comprises an upper spraying platform 1, a lower spraying platform 2 and a cooling device 3, wherein the upper spraying platform 1 and the lower spraying platform 2 are respectively installed with the cooling device 3, wherein the cooling device 3 is used to cool the strip located between the upper spraying platform 1 and the lower spraying platform 2, wherein the cooling device 3 comprises a spraying manifold 31 and a hydraulic cylinder 32, wherein the spraying manifold 31 is provided with a plurality of nozzles 34 in sequence along its extension direction, wherein the nozzle 34 is used to spray the cooling medium in the spraying manifold 31 into the middle area between the upper spraying platform 1 and the lower spraying platform 2, wherein hydraulic cylinders 32 are respectively installed at both ends of the spraying manifold 31, wherein the movable ends of the hydraulic cylinders 32 extend into the spraying manifold 31 and are used to reciprocate in the inner cavity of the spraying manifold 31 so as to control the number of the nozzles 34 spraying the cooling medium.

[0036] Specifically, the cooling system is mainly composed of an upper spraying platform 1, a lower spraying platform 2 and a cooling device 3. The upper spraying platform 1 and the lower spraying platform 2 are arranged opposite to each other, and the strip A is transmitted between the two. The cooling device 3 is respectively installed at the ends of the upper spraying platform 1 and the lower spraying platform 2 along the transmission direction of the strip A, and sprays cooling medium for the strip A located between the upper spraying platform 1 and the lower spraying platform 2, thereby cooling the strip A.

[0037] Furthermore, the cooling system is mainly used to cool the strip A between the upper spraying station 1 and the lower spraying station 2. During the production or processing of the strip A, heat may be generated due to various reasons, and the cooling device 3 can cool the strip A to a suitable temperature in time to ensure the performance and quality of the strip A. The spraying manifold 31 is provided with a plurality of nozzles 34 in sequence along its extension direction. The nozzles 34 are used to spray the high-pressure cooling medium in the spraying manifold 31 onto the strip A between the upper spraying station 1 and the lower spraying station 2. Since the upper spraying station 1 and the lower spraying station 2 are respectively provided with the spraying manifold 31, the upper and lower surfaces of the strip A therein can be sprayed at the same time, which greatly improves the spraying efficiency, so that the strip A can be quickly cooled.

[0038] It should be noted that the nozzle 34 can be a fan-shaped nozzle, which can produce a flat and uniform flat jet with good jet density. The diffusion angle can vary within a large range. Its process application varies according to the flow rate, flow rate, jet angle and coverage. By partially cross-spraying the jet beam, uniform coverage of the spray surface can be achieved. The flow rate or flow velocity of the fan-shaped nozzle is proportional to the square root of the fluid pressure, and its flow rate range can be from a few liters per minute at a pressure of 0.05MPa to more than 5L / s at a pressure of 3MPa. The fan-shaped nozzle 34 can achieve uniform jet and flat coverage, and can quickly process large areas. The adjustable diffusion angle also optimizes the operating speed and can ensure the quality of the spray treatment. The dense jet and uniform coverage ensure the consistency of the treatment. Accurate control of the flow rate and flow velocity can achieve specific effects and improve quality stability.

[0039] Specifically, the cooling device 3 is respectively installed at the ends of the upper spraying platform 1 and the lower spraying platform 2 along the running direction of the strip A. By adjusting the spraying manifold 31 to a suitable installation angle, the cooling medium therein can be sprayed onto the strip A through the nozzle 34 in the opposite direction of the running direction of the strip A. This reverse spraying method can more effectively remove the heat on the surface of the strip A and achieve rapid cooling. After the cooling medium is sprayed onto the strip A, it will flow out of the equipment along the middle area, ensuring the continuity and stability of the cooling process. Among them, the cooling process can be divided into a strong spray cooling stage and a turbulent weak cooling stage. In the strong spray cooling stage, the cooling medium is sprayed onto the strip A at a higher pressure and speed to quickly reduce the temperature of the strip A. After that, the cooling medium flows between the upper spraying platform 1 and the lower spraying platform 2 to form a turbulent weak cooling stage. The cooling medium in the turbulent weak cooling stage has a disordered flow, which can cool the strip A more evenly and further improve the cooling effect. Furthermore, since the width of the strip A may be different, in order to ensure the uniformity and efficiency of the cooling effect, it is necessary to adjust the cooling coverage width according to the different widths of the strip A, that is, by controlling the opening and closing of the nozzle 34, adjust the spray range of the cooling medium, so as to adapt to the strip A of different widths. When the width of the strip A is narrow, some nozzles 34 can be closed to reduce the waste of cooling medium and improve the spray cooling efficiency of the remaining nozzles in the open state; when the width of the strip A is wide, more nozzles 34 can be opened to ensure that the entire width of the strip A can be fully cooled and the uniformity of the cooling of the strip A is ensured. Hydraulic cylinders 32 are symmetrically installed at both ends of the injection manifold 31. The hydraulic cylinder 32 includes a hysteresis-strictive displacement sensor, a hydraulic cylinder body 321 and a piston rod 322. The hysteresis-strictive displacement sensor can monitor the position of the piston 323 in real time and provide accurate feedback information for the control system, thereby realizing precise control of the opening and closing of the nozzle 34. The hydraulic cylinder body 321 and the piston rod 322 are responsible for transmitting power to push the piston 323 located in the inner cavity of the injection manifold 31 to move. When the width of the strip A changes, the piston rod 322 drives the piston 323 in the inner cavity of the injection manifold 31 to move under the thrust of the hydraulic cylinder 32, thereby squeezing the cooling medium in the inner cavity toward the middle. Since the nozzle 34 is opened and closed by the pressure of the high-pressure cooling medium in the inner cavity to spray liquid, when the cooling medium is squeezed, the nozzles 34 at both ends that do not contact the cooling medium will close due to the loss of pressure, and only the nozzles 34 near the middle that contact the cooling medium will open due to the pressure and spray the cooling medium, so that the spray width of the injection manifold 31 can be adjusted by the hydraulic cylinder 32. According to the width of the strip A that needs to be cooled, the piston 323 is adjusted to a suitable position by the hydraulic cylinder 32, so that the spray width of the injection manifold 31 matches the width of the strip A.

[0040] In this embodiment, the upper spraying platform 1 and the lower spraying platform 2 are arranged oppositely and the cooling device 3 is installed respectively, and the spraying manifold 31 with multiple nozzles 34 is used to spray and cool the upper and lower surfaces of the strip A at the same time, which greatly improves the spraying efficiency, can quickly cool the strip A, and through the turbulent flow of the cooling medium, the strip A is cooled more evenly, and the cooling effect is further improved. The spraying width of the cooling medium is adjusted according to the different widths of the strip A, that is, the nozzle 34 on the spraying manifold 31 is controlled to open and close according to the width of the strip A by the hydraulic cylinder 32, so as to control the spraying width of the cooling medium, avoid the waste of cooling medium, and ensure that the strips A of different widths can be fully cooled. At the same time, the spraying width is adjusted by the hydraulic cylinder 32, so that the spraying width of the spraying manifold 31 matches the width of the strip A, ensuring the uniformity and efficiency of the cooling effect, and can effectively improve the cooling efficiency of the strip A.

[0041] Alternatively, if Figure 4 As shown, the hydraulic cylinder 32 includes a hydraulic cylinder body 321 and a piston rod 322. One end of the piston rod 322 is arranged in the inner cavity of the hydraulic cylinder body 321, and the other end of the piston rod 322 is arranged in the inner cavity of the injection manifold 31. The other end of the piston rod 322 is provided with a piston 323. The piston 323 is in contact with the inner wall of the inner cavity of the injection manifold 31. The piston rod 322 is used to drive the piston 323 to reciprocate in the inner cavity of the injection manifold 31 along the extension direction of the injection manifold 31. The piston 323 is used to control the number of the nozzles 34 that spray the cooling medium through reciprocating motion in the inner cavity.

[0042] Specifically, the hydraulic cylinder body 321 is the main structure of the hydraulic cylinder 32, providing support and protection for the internal components. Its inner cavity is the space for the piston rod 322 and the piston 323 located therein to move, and has a certain strength and sealing performance to ensure that the working medium such as hydraulic oil can stably transmit pressure therein. One end of the piston rod 322 is arranged in the inner cavity of the hydraulic cylinder body 321, which plays the role of connecting the hydraulic cylinder 32 and the injection manifold 31. The piston rod 322 can perform linear motion in the inner cavity of the hydraulic cylinder body 321, and transmit the power generated by the hydraulic cylinder 32 to the inner cavity of the injection manifold 31. The other end of the hydraulic rod is arranged in the inner cavity of the injection manifold 31, connected to the piston 323, and the movement of the piston rod 322 directly drives the piston 323 to reciprocate in the inner cavity of the injection manifold 31.

[0043] Furthermore, the piston 323 disposed at the other end of the piston rod 322 is located in the inner cavity of the injection manifold 31, and the piston 323 is closely fitted with the inner wall of the inner cavity of the injection manifold 31 to ensure that the flow of the cooling medium can be effectively controlled during the movement, and the cooling medium is blocked through the piston 323. Figure 5As shown, one side of the piston 323 is a cooling medium area B, and the other side is a cooling medium-free area A. The opening and closing nozzle D on the side of the cooling medium area B is opened due to the pressure of the cooling medium and can spray the cooling medium, while the closing nozzle C on the side of the cooling medium-free area A is closed due to the loss of the cooling medium pressure. In addition, there is no cooling medium in this area due to the obstruction of the piston 323, so the cooling medium cannot be sprayed. Therefore, the piston 323 is driven by the piston rod 322 to reciprocate in the inner cavity of the spray manifold 31 along the extension direction of the spray manifold 31, and the nozzles 34 at different positions can be controlled to open and close. When the piston 323 moves to a position close to the middle of the spray manifold 31, some nozzles 34 are blocked by the piston 323, and no cooling medium is sprayed from these nozzles 34, thereby reducing the number of nozzles 34 spraying the cooling medium, that is, reducing the spray width of the cooling medium in the spray manifold 31. On the contrary, when the piston 323 moves to a position away from the center of the injection manifold 31, more nozzles 34 contacting the cooling medium are opened, and the cooling medium can be sprayed out from these nozzles 34, increasing the number of nozzles 34 spraying the cooling medium, that is, increasing the spray width of the cooling cutoff in the injection manifold 31. In this way, the number of nozzles 34 spraying the cooling medium can be accurately controlled according to actual needs to achieve the adjustment of the spray width of the cooling medium sprayed from the injection manifold 31.

[0044] In this optional embodiment, the number of nozzles 34 is controlled by the piston rod 322 driving the piston 323 to reciprocate in the inner cavity of the spray manifold 31, and the spray range and intensity of the coolant can be flexibly adjusted according to strips of different widths and different cooling requirements. For narrower strips, the number of nozzles 34 can be reduced to avoid waste of cooling medium; for strips that require stronger cooling effects, the number of nozzles 34 can be increased to improve cooling efficiency.

[0045] Optionally, the hydraulic cylinder 32 also includes an intermediate isolation ring 324 and a connecting piece 326, wherein the intermediate isolation ring 324 is sleeved on the piston rod 322, and the inner wall of the intermediate isolation ring 324 is in contact with the outer wall of the piston rod 322, and an annular protrusion 325 is provided in the middle of the outer wall of the intermediate isolation ring 324, and the annular protrusion 325 is located between the hydraulic cylinder body 321 and the injection manifold 31, and the hydraulic cylinder body 321, the annular protrusion 325 and the injection manifold 31 are fixedly connected by the connecting piece 326.

[0046] Specifically, Figure 4As shown, an annular protrusion 325 is provided in the middle of the outer wall of the intermediate isolating ring 324. This annular protrusion 325 plays a key role in connection and positioning in the entire device. The intermediate isolating ring 324 is respectively arranged in the inner cavity of the hydraulic cylinder body 321 and the injection manifold 31. It forms an isolation layer between the two components, which helps to maintain the independence and sealing of the hydraulic cylinder 32 and the injection manifold 31. The inner wall fits with the outer wall of the piston rod 322 to ensure the stability and linearity of the piston rod 322 during movement. The fit can also reduce the shaking and deviation of the piston rod 322, improve the working accuracy and reliability of the hydraulic cylinder 32, and better isolate the hydraulic cylinder 32 from the inside of the injection manifold 31.

[0047] Furthermore, the annular protrusion 325 is arranged between the hydraulic cylinder body 321 and the injection manifold 31, and the hydraulic cylinder body 321, the annular protrusion 325 and the injection manifold 31 are fixedly connected together by the connecting piece 326, so that the hydraulic cylinder 32 and the injection manifold 31 can maintain a relatively stable positional relationship during the working process, and prevent displacement or loosening due to vibration or external force. At the same time, the intermediate isolation ring 324 and the annular protrusion 325 made of elastic material can also play a certain sealing role, which can reduce the gap between the hydraulic cylinder 32 and the injection manifold 31, prevent the leakage of coolant or other media, and ensure the normal operation of the cooling system. The connecting piece 326 firmly fixes the hydraulic cylinder body 321, the annular protrusion 325 and the injection manifold 31 together, ensuring the stability and reliability of the entire device during the working process. Through this fixed connection, it can withstand the pressure generated by the hydraulic cylinder 32 and the movement force of the piston rod 322, and prevent separation or damage between components. Moreover, the connector 326 can be a bolt, which is fixedly connected by the through holes of the protruding structures at both ends of the hydraulic cylinder body 321 and the injection manifold 31. The design of the connector 326 should be easy to install and disassemble, so that the hydraulic cylinder 32 and the injection manifold 31 can be maintained and repaired when necessary. A reasonable connector 326 can improve the maintainability of the device and reduce maintenance costs and downtime. The piston rod 322 is inserted into the inner ring of the intermediate isolation ring 324. The inner ring of the intermediate isolation ring 324 provides a guide channel for the piston rod 322 to ensure that the piston rod 322 always remains in the correct position during the movement, which helps to improve the working accuracy and stability of the hydraulic cylinder 32 and reduce the friction and wear between the piston rod 322 and other components. The inner wall of the intermediate isolation ring 324 fits the outer wall of the piston rod 322, which can not only play a sealing role to prevent medium leakage, but also play a certain protective role for the piston rod 322, which can reduce the influence of the external environment on the piston rod 322 and extend the service life of the piston rod 322.

[0048] In this optional embodiment, the device stability is enhanced by the connector 326 and the annular protrusion 325, ensuring that it remains stable when subjected to pressure and impact during operation, and that it is accurately positioned to achieve precise cooling, while also improving the sealing, preventing coolant leakage, reducing resource waste, ensuring work efficiency, and protecting the environment. The movement of the piston rod 322 is optimized by the intermediate isolation ring 324, providing guidance to make the movement smoother and reduce wear, while also playing a protective isolation role, and connected by a detachable connection mechanism for easy maintenance and repair, the connector 326 is easy to disassemble and assemble, and the intermediate isolation ring 324 is also conducive to checking the state of the piston rod 322.

[0050] Specifically, Figure 6As shown, the upper spraying platform 1 includes an upper spraying platform body 11 and a movable baffle mechanism 12. The upper spraying platform body 11 is the main structure of the upper spraying platform 1, providing support for the cooling process and a basis for installing other components. The upper spraying platform body 11 is provided with hollow structures at both ends, and the two hollow structures are respectively located on both sides of the strip. The hollow structure provides space for the installation and movement of the movable baffle mechanism 12. The movable baffle mechanism 12 is composed of a baffle structure 121, a suspension structure and a rotating device 123. The movable baffle mechanisms 12 at the two hollow areas are used to jointly achieve adaptive adjustment of the strip width. The baffle structure 121 is suspended in the two hollow structures of the upper spraying platform body 11 through the suspension structure, and the bottom surface of the baffle structure 121 is fitted with the upper surface of the lower spraying platform 2, so that the two baffle structures 121 and the upper spraying platform 1 and the lower spraying platform 2 form a cooling area together, ensuring that the coolant can act on the strip in the cooling area in a concentrated manner, thereby improving the cooling efficiency. The main function of the baffle structure 121 is to adjust the size of the cooling area according to the width of the strip to prevent the coolant from leaking to the area that does not need cooling. The suspension structure serves to connect the baffle structure 121 and the upper spray table body 11. The baffle structure 121 can be flexibly moved in the hollow structure through the suspension structure to adapt to strips of different widths. The suspension structure should have sufficient strength and stability to ensure that the baffle structure 121 will not fall off or shake during operation. The rotating device 123 is arranged on the upper surface of the upper spray table body 11 and is movably connected to the baffle structure 121. The rotating device 123 can automatically or manually adjust the position of the baffle structure 121 in the hollow structure according to the width of the strip. When the width of the strip changes, the rotating device 123 drives the baffle structure 121 to move in the hollow structure by rotating or moving, thereby changing the size of the cooling area to adapt to the new strip width.

[0051] In this optional embodiment, the cooling area can be adjusted according to the width of the strip through the movable baffle mechanism 12, so that the coolant acts on the strip in a concentrated manner, improving the cooling efficiency, while preventing coolant leakage and reducing costs. At the same time, the rotating device 123 can quickly respond to changes in the strip width to adjust the baffle position, enhance the adaptability to different strip widths, and improve production efficiency and flexibility. In addition, the stability of the equipment is improved through a stable suspension structure and a reasonable layout, and the easy-to-operate rotating device 123 is easy to maintain and adjust, reducing maintenance costs and operating difficulties.

[0052] Optionally, a first through hole is provided at the upper end of the baffle structure 121 , and the suspension structure includes a guide rod 122 . The guide rod 122 is passed through the first through hole and is fixedly connected to the upper spraying platform body 11 .

[0053] Specifically, Figure 6As shown, after the guide rod 122 is passed through the first through hole at the upper end of the movable baffle mechanism 12, it is fixedly connected to the upper spray table body 11 on both sides of the hollow structure. The guide rod 122 plays a guiding and supporting role in the suspension and movement of the movable baffle mechanism 12. The guide rod 122 ensures that the movable baffle mechanism 12 can move in a specific direction in the hollow structure, avoiding the movable baffle mechanism 12 from deflecting or shaking during the process of adjusting the position, thereby improving the movement accuracy of the movable baffle mechanism 12, so that it can accurately adjust the cooling area according to the width of the strip. At the same time, the guide rod 122 provides a stable support for the movable baffle mechanism 12, bearing the weight of the movable baffle mechanism 12 and external forces such as the coolant pressure that may be received during the cooling process. Ensure that the movable baffle mechanism 12 will not deform or fall off during the working process, and ensure the normal operation of the cooling system.

[0054] In this optional embodiment, the guide rod 122 provides precise guidance for the movement of the movable baffle mechanism 12 in the hollow structure, ensuring that the baffle can accurately adjust its position according to the width of the strip, improving the adjustment accuracy of the cooling area and the uniformity and stability of the cooling effect. In addition, the guide rod 122 is fixedly connected to the upper spray table body 11 to provide reliable support for the movable baffle mechanism 12, enhance structural stability, reduce vibration, extend the service life of the equipment and improve the safety of the cooling process.

[0055] Optionally, the rotating device 123 includes a ball screw 1234, a universal joint 1233, a commutator 1232 and a power device 1231, the power device 1231 and the commutator 1232 are respectively fixed in the middle of the upper surface of the upper injection platform body 11, the power device 1231 is connected to the input shaft end of the commutator 1232, the output shaft end of the commutator 1232 is connected to one end of the universal joint 1233, the other end of the universal joint 1233 is connected to one end of the ball screw 1234, the upper end of the baffle structure 121 is provided with a screw nut 1211, the ball screw 1234 is used to be inserted into the screw nut 1211, and the two ends of the ball screw 1234 are respectively mounted on the upper injection platform body 11 on both sides of the hollow structure, and are rotatably connected to the upper injection platform body 11.

[0056] Specifically, Figure 6As shown, the power device 1231 and the commutator 1232 are respectively fixed on the middle part of the upper surface of the upper injection table body 11. The power device 1231 serves as a power source to provide power for the entire rotating device 123. The power device 1231 is connected to the commutator 1232 through a connecting shaft or directly to the input shaft end of the commutator 1232 to transmit the power to the commutator 1232. The commutator 1232 plays a role in changing the direction of the power. The output shaft ends thereof are respectively connected to one end of two universal joints 1233 to transmit the power after the direction conversion to the universal joint 1233. The universal joint 1233 serves as a connecting component and can adapt to the power transmission requirements at different angles to a certain extent. The other ends of the two universal joints 1233 are respectively connected to ball screws 1234, which are key components for adjusting the position of the baffle structure 121. The rotational power transmitted by the universal joint 1233 drives the ball screw 1234 to rotate, and the two baffle structures 121 are respectively driven to move by the rotation of the two ball screws 1234. A screw nut 1211 is provided at the upper end of the baffle structure 121, and the ball screw 1234 is inserted into the screw nut 1211. When the ball screw 1234 rotates, due to the cooperation with the screw nut 1211, the movable baffle mechanism 12 will move linearly along the axial direction of the ball screw 1234. The two ends of the ball screw 1234 are rotatably connected to the upper injection platform body 11 on both sides of the hollow structure respectively. Rotary bearings can be set at corresponding positions on both sides. The two ends of the ball screw 1234 are fixed on the upper injection platform body 11 through the rotary bearings, and the ball screw 1234 can be kept rotatable, while also providing stable support for the movement of the movable baffle mechanism 12.

[0057] Furthermore, the power required by the rotating device 123 is provided by the power device 1231, which may be an electric motor, a hydraulic motor, etc. The performance of the power device 1231 determines the adjustment speed and accuracy of the rotating device 123. According to different strip width adjustment requirements, the power device 1231 with appropriate power and speed can be selected. The main function of the commutator 1232 is to change the direction of the power. In actual installation, due to space limitations or other factors, the output direction of the power device 1231 may be inconsistent with the required direction of the ball screw 1234. The commutator 1232 converts the power of the power device 1231 into a direction suitable for the ball screw 1234 through internal gears or other mechanical structures to ensure effective transmission of power. The universal joint 1233 can transmit power within a certain angle range. In actual work, since the upper injection platform body 11 may be affected by factors such as vibration, thermal expansion and contraction, the relative positions between the power device 1231, the commutator 1232 and the ball screw 1234 may change. The universal joint 1233 can adapt to this change, ensure the stable transmission of power, and avoid power loss or device damage caused by angle changes. The ball screw 1234 converts power into linear motion of the movable baffle mechanism 12 through rotational motion. The ball screw 1234 has the characteristics of high precision and high transmission efficiency, and can realize precise adjustment of the position of the movable baffle mechanism 12. According to different cooling requirements and the range of strip width changes, ball screws 1234 with different pitches and diameters can be selected to meet different adjustment accuracy and speed requirements. The main function of the movable baffle mechanism 12 is to adjust the size of the cooling area according to the width of the strip. By cooperating with the ball screw 1234, the movable baffle mechanism 12 can move flexibly in the hollow structure to achieve precise control of the cooling area. The setting of the screw nut 1211 enables the movable baffle mechanism 12 to cooperate closely with the ball screw 1234 to ensure effective power transmission and accuracy of position adjustment.

[0058] Optionally, the baffle structure 121 includes a fixed baffle 1212, a movable baffle 1213, a swinging baffle 1214, a guide pin 1215 and a pin shaft 1216. The fixed baffle 1212 is provided with a guide groove 12121 at the bottom, and circular through holes 12122 are provided on both sides of the guide groove 12121. The upper end of the movable baffle 1213 is provided with a first rectangular through hole 12131, and the length direction of the first rectangular through hole 12131 is a vertical direction. The upper end of the movable baffle 1213 is arranged in the guide groove 12121, and the guide pin 1215 is penetrated through the circular through hole 12122 and the first rectangular through hole 12131. The lower end of the movable baffle 1213 and the swinging baffle 1214 are rotatably connected by the pin shaft 1216, and the lower surface of the swinging baffle 1214 is in contact with the upper surface of the lower injection platform 2.

[0059] Specifically, Figure 7 As shown, the fixed baffle 1212 serves as the base of the baffle structure 121 to provide support and installation position for other components. A guide groove 12121 is provided at the bottom, and circular through holes 12122 are provided on both sides of the guide groove 12121 for connecting and positioning with the movable baffle 1213. A first rectangular through hole 12131 is provided at the upper end of the movable baffle 1213, and its position matches the circular through hole 12122 on the fixed baffle 1212. The diameter of the circular through hole 12122 matches the width of the first rectangular through hole 12131, so that the guide pin 1215 can smoothly pass through the two to achieve the connection between the fixed baffle 1212 and the movable baffle 1213. The length direction of the first rectangular through hole 12131 is the vertical direction. This design enables the movable baffle 1213 to move vertically within a certain range when subjected to a force in a specific direction, so that the connected movable baffle 1213 can be suspended below the fixed baffle 1212. The upper end of the movable baffle 1213 is set in the guide groove 12121 of the fixed baffle 1212, and is connected to the fixed baffle 1212 through the guide pin 1215, and performs relative movement under the restriction of the guide groove 12121. Among them, the first rectangular through hole 12131 may include a standard rectangle, that is, this is the most common shape, with a significant difference in length and width, and four right angles. The first rectangular through hole 12131 of this shape provides a relatively stable guide for the movable baffle 1213 in the vertical direction, so that the movable baffle 1213 can move up and down more smoothly in the guide groove 12121 of the fixed baffle 1212. It can also include a rectangular rounded rectangle, that is, the first rectangular through hole 12131 with four rounded corners can reduce stress concentration and improve the strength of the movable baffle 1213. When the movable baffle 1213 moves up and down, the rounded corners can reduce the friction between the guide pin 1215 and make the movement smoother.

[0060] Furthermore, the swing baffle 1214 is rotatably connected to the lower end of the movable baffle 1213 via a pin 1216. This connection mode enables the swing baffle 1214 to swing freely within a certain angle range to adapt to the changes in the surface under different working conditions. The lower surface of the swing baffle 1214 fits the upper surface of the lower spraying table 2 to form a relatively closed cooling space to prevent the coolant from leaking to the area that does not need cooling.

[0061] In this optional embodiment, the combination of the fixed baffle 1212, the movable baffle 1213 and the swing baffle 1214 can accurately adjust the cooling area according to the size of the strip. The coolant can act on the strip more effectively, reduce the occurrence of uneven cooling, and improve the cooling quality of the strip. At the same time, the lower surface of the swing baffle 1214 fits with the upper surface of the lower spraying table 2 to form a relatively closed cooling space. Even if the surface is uneven or slightly undulating, the swing baffle 1214 can automatically adjust the angle to keep fitting, prevent coolant leakage, ensure that the cooling medium acts on the strip, and improve the stability of the cooling effect.

[0062] Optionally, the baffle structure 121 further includes an elastic component 1217 , and both ends of the swing baffle 1214 are connected to the movable baffle 1213 via the elastic component 1217 .

[0063] Specifically, Figure 7 As shown, the elastic component 1217 is located between the swing baffle 1214 and the movable baffle 1213, and the two ends of the swing baffle 1214 are connected to the movable baffle 1213 respectively. The elastic component 1217 can be made of a spring or other elastic material. The connection of the elastic component 1217 can enable the swing baffle 1214 to obtain a certain elastic buffer and adjustment space through the elastic component 1217 while working in coordination with the movable baffle 1213. The movable baffle 1213 can move by its own weight to compensate for the installation error in the vertical direction, and the swing baffle 1214 can compensate for the angular error generated when it fits the lower table and the angular error generated by the installation. When the upper table is closed, one end of the swing baffle 1214 first contacts the lower table, so that the swing baffle 1214 can swing at this time. If it cannot swing, it cannot be closed.

[0064] Optionally, the cooling device 3 also includes a clamp 33, which includes a first semicircular clamp 331 and a second semicircular clamp 332, one end of the first semicircular clamp 331 and one end of the second semicircular clamp 332 are rotatably connected, the other end of the first semicircular clamp 331 and the other end of the second semicircular clamp 332 are bolted together, and the first semicircular clamp 331 and the second semicircular clamp 332 are connected to form a circular through hole 12122, the diameter of the circular through hole 12122 matches the diameter of the injection manifold 31, and the circular through hole 12122 is used to penetrate the injection manifold 31.

[0065] Specifically, Figure 8As shown, the clamping plate 33 is composed of two semicircular parts, namely the first semicircular clamping plate 331 and the second semicircular clamping plate 332. The design of the two semicircular clamping plates allows them to be assembled and disassembled around the injection manifold 31, which is convenient for installation and maintenance. One end of the first semicircular clamping plate 331 and one end of the second semicircular clamping plate 332 are connected together by a rotating connection. This connection method allows the two semicircular clamping plates to be relatively rotated to open or close, which is convenient for operation during installation and disassembly. The rotating connection can be achieved by hinges, pins 1216, etc. to ensure the flexibility and stability of the connection. The other end of the first semicircular clamping plate 331 is connected to the other end of the second semicircular clamping plate 332 by bolts. The bolt connection provides a firm fixing method to ensure that the clamping plate 33 can tightly wrap the injection manifold 31 during operation to prevent the clamping plate from loosening or falling off. The number and specifications of the bolts can be selected according to actual needs to ensure the strength and reliability of the connection. When the bolts are loosened, the injection manifold 31 can rotate in the circular through hole 12122 of the clamping plate 33, thereby adjusting the injection angle of the nozzle 34. Thus, the spraying manifolds 31 located at the upper spraying platform 1 and the lower spraying platform 2 spray the strip symmetrically, avoiding the vibration of the strip caused by the asymmetric spraying area. By adjusting the angle of the nozzle 34 and the vertical position of the upper spraying manifold 31, the upper and lower spraying areas can be made nearly symmetrical, thereby reducing the vibration of the strip. This design provides a flexible adjustment method for the strip cooling process, helps to improve the cooling effect and strip quality, and reduces the adverse effects caused by asymmetric spraying.

[0066] Optionally, the clamp 33 also includes a fixing bolt 335 and an adjusting bolt 336, as well as a first side arm 333 extending in sequence along the other end of the first semicircular clamp 331 and a second side arm 334 perpendicular to the first side arm 333, the first side arm 333 is provided with a second rectangular through hole, and the upper spraying platform 1 is provided with a screw hole at one end along the traveling direction of the strip, the fixing bolt 335 passes through the second rectangular through hole and is connected to the screw hole of the upper spraying platform 1, the second side arm 334 is provided with a second through hole, and the inner wall of the second through hole is provided with a thread, and the adjusting bolt 336 is used to pass through the second through hole and abut against the upper surface of the upper spraying platform 1.

[0067] Specifically, the first side arm 333 extending from the other end of the first semicircular clamp 331 is used to connect the clamp 33 with the upper spray platform 1, that is, a second rectangular through hole is provided on the first side arm 333, and a corresponding screw hole is provided on the side of the upper spray platform 1 along the traveling direction of the strip, and the fixing bolt 335 passes through the second rectangular through hole and is connected to the screw hole. The first semicircular clamp 331 is fixedly connected to the upper spray platform 1 by rotating and tightening the fixing bolt 335 with the screw hole in the upper spray platform 1, and the vertical position of the clamp 33 and the spray collection pipe 31 passing through the clamp 33 is adjusted by adjusting the vertical position of the fixing bolt 335 in the rectangular through hole. At the same time, the second side arm 334 is provided with a second through hole with a thread on the inner wall, and the adjusting bolt 336 passes through the second through hole with a thread and contacts the upper surface of the upper injection platform 1. By controlling the adjusting bolt 336 to rotate out of the second through hole and abut against the upper surface of the upper injection platform 1, the vertical position of the clamp is further limited by the rotation distance of the adjusting bolt 336, thereby avoiding the change of the vertical position of the clamp and the injection collection pipe 31 due to the loosening of the fixing bolt 335.
