Description

Technical Field

[0001] The invention belongs to the technical field of stainless steel production equipment, in particular to a novel lubrication and cooling device for cold-rolled stainless steel production. Background Art

[0002] In the cold-rolled stainless steel production process, the lubrication and cooling device is the core equipment to ensure the surface quality of the plate and extend the life of the roller. Traditional cooling systems mostly use fixed dampers to adjust the hot air flow, and cooperate with linear cooling pipes and basic liquid cooling cycles to achieve cooling. The cooling path design is usually a single flow direction, relying on manual monitoring or simple temperature control valves to achieve flow regulation. The coolant circulation is mostly driven by a conventional pump body, and the heat dissipation structure generally uses flat heat sinks. When dealing with complex working conditions, such devices often have problems such as delayed temperature response and insufficient cooling uniformity. Especially when dealing with high-temperature hot air generated by high-intensity continuous rolling, it is easy for the cooling capacity to not match the heat load.

[0003] Traditional lubrication cooling devices have significant defects: first, the fixed air volume adjustment mechanism cannot dynamically adjust the air intake according to the hot air temperature, resulting in insufficient cooling capacity under high temperature conditions or energy waste at low temperatures; second, the contact area of ​​the linear cooling pipe is limited, the heat exchange efficiency is low, and there is a lack of path adaptive extension mechanism, making it difficult to cope with sudden temperature rise; third, the rigid connection of the mechanical adjustment components is prone to wear due to frequent movement, affecting the sealing and adjustment accuracy, and the heat dissipation efficiency of the coolant circulation system is limited by the static heat dissipation structure, and rapid thermal balance cannot be achieved. In addition, the pipe joints are prone to leakage due to thermal stress deformation, further restricting the stability of the system. These defects together make it difficult for traditional devices to meet the needs of modern cold-rolled stainless steel efficient production in terms of cooling efficiency, temperature control accuracy and equipment durability. Therefore, they need to be improved and optimized. Summary of the invention

[0004] In order to solve the problem raised in the above background technology that traditional lubrication and cooling devices have significant defects in cooling efficiency, temperature control accuracy and equipment durability, and are difficult to meet the needs of modern cold-rolled stainless steel efficient production, the present invention provides a new type of lubrication and cooling device for cold-rolled stainless steel production.

[0005] To achieve the above object, the present invention provides the following technical solution: a new type of lubrication and cooling device for cold-rolled stainless steel production, comprising an outer box, an inner box is fixedly installed inside the outer box, three groups of heat dissipation fins are fixedly installed on the outer wall of the outer box, a first adjustment mechanism is arranged on the outer wall of the outer box, and a second adjustment mechanism is arranged inside the inner box;

[0006] The first adjustment mechanism includes a rectangular box fixedly installed on the outer wall of one side of the outer box. An air suction pipe is fixedly installed on one side of the rectangular box. A regulating plate is hingedly installed on the inner wall of the bottom of the rectangular box. The regulating plate is inclined, and the bottom of the regulating plate is elastically connected to the inner wall of the rectangular box through two spring telescopic rod assemblies II. Two sets of adjusting components are arranged inside the rectangular box. The two sets of adjusting components are symmetrically distributed along the horizontal axis. An airbag is arranged in the middle of the two sets of adjusting components. The adjusting component includes two funnel-shaped baffles fixedly installed on the inner wall of the rectangular box. T-shaped columns are slidably installed on the inner walls of the two funnel-shaped baffles. The T-shaped columns and the funnel-shaped baffles are elastically connected through two spring telescopic rod assemblies I.

[0007] Preferably, the T-shaped column in the lower adjusting component is bent at a right angle and contacts the top of the regulating plate. The funnel-shaped baffle and the T-shaped column in the lower adjusting component are both of a double-layer design with a hollow middle.

[0008] Preferably, the tops of the two funnel-shaped baffles in the upper adjusting component are respectively folded 90 degrees towards the inner wall of the corresponding rectangular box, so that the tops of the two spring telescopic rod assemblies I are connected to the folded T-shaped columns.

[0009] Preferably, two branch pipes extend from the bottom of the air suction pipe and are both fixedly connected to the rectangular box. The upper branch pipe is above the airbag, and the lower branch pipe is below the airbag.

[0010] Preferably, an air pump is fixedly installed on the side of the outer box away from the heat dissipation fins. A water inlet pipe is fixedly installed at the water suction end of the air pump. The other end of the water inlet pipe extends into the inner box. A water outlet pipe is fixedly installed at the water outlet end of the air pump. The other end of the water outlet pipe extends into the outer box.

[0011] Preferably, the second adjustment mechanism includes three U-shaped pipes I and a U-shaped pipe II. An air inlet pipe, an air outlet pipe, and the U-shaped pipe II form a corrugated pipe. One end of the air inlet pipe extends outside the outer box and is fixedly connected to the rectangular box. One end of the air outlet pipe extends outside the outer box.

[0012] Preferably, connection frames are fixedly installed on the tops of the three U-shaped pipes II. An L-shaped rod is fixedly installed on the top of the connection frame. The L-shaped rod extends outside the outer box and is slidably connected to the outer box. The other end of the L-shaped rod is fixedly connected to the corresponding T-shaped column.

[0013] Preferably, the three U-shaped pipes I are above the three U-shaped pipes II and the U-shaped pipes I and the U-shaped pipes II are spaced apart. The corresponding U-shaped pipe II is fixedly connected to the air inlet pipe, and the corresponding U-shaped pipe I is fixedly connected to the air outlet pipe. Bellows are installed at both ends of the three U-shaped pipes II. Several bellows are respectively fixedly connected to the corresponding U-shaped pipe I and the air inlet pipe.

[0014] Preferably, hollow tubes are respectively and slidably installed on the inner walls of one ends of the three U-shaped tubes II that coincide with the vertical direction of the U-shaped tube I, and a plurality of the hollow tubes are respectively fixedly connected to the corresponding U-shaped tube I.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] Based on the principle of thermal expansion and contraction of the airbag, the present invention intelligently responds to the change of hot air temperature. When the hot air temperature rises, the airbag expands and pushes the T-shaped column in the adjustment component to move, thereby adjusting the amount of hot air entering the inner box to achieve adaptive temperature control. The U-shaped tube II in the second adjustment mechanism can also automatically adjust its height according to the change of hot air temperature, extending or shortening the cooling path of the hot air, thereby enhancing the cooling effect. The adaptive adjustment mechanism ensures that the device can maintain the best cooling effect under different working conditions.

[0018] By adopting the design of a corrugated pipe, the present invention greatly increases the flow path and cooling area of the hot air, improves the cooling efficiency. Through the efficient operation of the air pump, the rapid circulation of the coolant is realized, further enhancing the cooling effect. The heat dissipation fins on the outer box effectively enhance the heat dissipation effect of the coolant, ensuring that the temperature of the coolant can be rapidly reduced during the circulation process. Through the design of efficient cooling and rapid circulation, the device can more effectively absorb and remove the heat in the hot air, ensuring the temperature control during the cold rolling stainless steel production process.

[0019] Through the elastic connection design of the spring telescopic rod assembly, the present invention enables components such as the adjustment plate and the T-shaped column to maintain stability during movement, reducing the possibility of wear and failure. The design of the corrugated pipe not only ensures the flexible connection between the U-shaped tube I and the U-shaped tube II, but also prevents the leakage of the coolant during the movement of the pipeline.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 to 11 shown, the present invention provides a new type of lubricating and cooling device for cold-rolled stainless steel production, including an outer box 1, an inner box 2 is fixedly installed inside the outer box 1, three groups of heat dissipation fins 101 are fixedly installed on the outer wall of the outer box 1, a first adjustment mechanism is arranged on the outer wall of the outer box 1, and a second adjustment mechanism is arranged inside the inner box 2;

[0034] The first adjustment mechanism includes a rectangular box 3 fixedly installed on one outer wall of the outer box 1. An air suction pipe 31 is fixedly installed on one side of the rectangular box 3. A regulating plate 5 is hingedly installed on the bottom inner wall of the rectangular box 3. The regulating plate 5 is inclined, and the bottom of the regulating plate 5 is elastically connected to the inner wall of the rectangular box 3 through two spring telescopic rod assemblies II 501. There are two sets of adjustment components inside the rectangular box 3. The two sets of adjustment components are symmetrically distributed along the horizontal axis. An airbag 4 is arranged in the middle of the two sets of adjustment components. The adjustment component includes two funnel-shaped baffles 301 fixedly installed on the inner wall of the rectangular box 3. T-shaped columns 3011 are slidably installed on the inner walls of the two funnel-shaped baffles 301. The T-shaped columns 3011 and the funnel-shaped baffles 301 are elastically connected through two spring telescopic rod assemblies I 3012. The bottom of the air suction pipe 31 extends out two branch pipes which are both fixedly connected to the rectangular box 3. The upper branch pipe is above the airbag 4, and the lower branch pipe is below the airbag 4. Among them, the T-shaped column 3011 in the lower adjustment component is bent by 90 degrees and contacts the top of the regulating plate 5. The funnel-shaped baffle 301 and the T-shaped column 3011 in the lower adjustment component are both of a double-layer design with a hollow middle. The tops of the two funnel-shaped baffles 301 in the upper adjustment component are respectively folded by 90 degrees towards the corresponding inner wall of the rectangular box 3, so that the tops of the two spring telescopic rod assemblies I 3012 are connected to the folded T-shaped columns 3011.

[0035] Based on the principle of thermal expansion and contraction of the airbag 4, it intelligently responds to the change of hot air temperature. When the hot air temperature rises, the airbag 4 expands, pushing the T-shaped columns 3011 in the upper and lower two sets of adjustment components to move correspondingly. The lower T-shaped column 3011 contacts and presses the regulating plate 5, changing the gap size between the regulating plate 5 and the branch pipe of the air suction pipe 31, so as to intelligently adjust the amount of hot air entering the inner box 2 and realize adaptive temperature control. The precise design of the funnel-shaped baffle 301 and the T-shaped column 3011 not only ensures the smooth flow of hot air, but also realizes the smooth movement of the T-shaped column 3011 when the airbag 4 expands through the elastic connection of the spring telescopic rod assembly I 3012. The double-layer design with a hollow middle enables the hot air to pass through smoothly while maintaining the strength and stability of the structure. The three groups of heat dissipation fins 101 on the outer box 1 effectively enhance the heat dissipation effect of the coolant, ensuring that the coolant can quickly reduce the temperature during the circulation process.

[0036] As Figure 1 and Figure 11 shown, an air pump 7 is fixedly installed on one side of the outer box 1 away from the heat dissipation fins 101. A water inlet pipe 701 is fixedly installed at the water suction end of the air pump 7. The other end of the water inlet pipe 701 extends into the inner box 2. A water outlet pipe 702 is fixedly installed at the water outlet end of the air pump 7. The other end of the water outlet pipe 702 extends into the outer box 1.

[0037] By starting the air pump 7, the water inlet pipe 701 extracts the coolant with a higher temperature in the inner box 2, while the water outlet pipe 702 sends the cooled coolant back into the outer box 1, realizing the rapid circulation of the coolant, effectively improving the cooling efficiency. The air pump 7 is equipped with a temperature sensor, which can automatically adjust the working state of the air pump 7 according to the temperature of the coolant. When the coolant temperature is too high, the air pump 7 accelerates its operation to increase the coolant circulation speed, thereby reducing the temperature more quickly. Through the efficient operation of the air pump 7 and combined with the heat dissipation effect of the heat dissipation fins 101, the performance of the entire cooling system is jointly improved, enabling the coolant to be continuously cooled during the circulation process, thus more effectively absorbing and taking away the heat in the hot air, ensuring the temperature control during the cold-rolled stainless steel production process.

[0038] As Figure 3 , Figures 8 to 10 shown, the second adjustment mechanism includes three U-shaped pipes I 6 and U-shaped pipes II 63, a corrugated pipe composed of an air inlet pipe 61, an air outlet pipe 62 and the U-shaped pipe II 63. One end of the air inlet pipe 61 extends outside the outer box 1 and is fixedly connected to the rectangular box 3. One end of the air outlet pipe 62 extends outside the outer box 1. Connecting frames 64 are fixedly installed at the tops of the three U-shaped pipes II 63. An L-shaped rod 65 is fixedly installed at the top of the connecting frame 64. The L-shaped rod 65 extends outside the outer box 1 and is slidably connected to the outer box 1. The other end of the L-shaped rod 65 is fixedly connected to the corresponding T-shaped column 3011. The three U-shaped pipes I 6 are located above the three U-shaped pipes II 63 and the U-shaped pipes I 6 and the U-shaped pipes II 63 are distributed at intervals. The corresponding U-shaped pipes II 63 are fixedly connected to the air inlet pipe 61, and the corresponding U-shaped pipes I 6 are fixedly connected to the air outlet pipe 62. Bellows 602 are respectively installed at both ends of the three U-shaped pipes II 63. A plurality of bellows 602 are respectively fixedly connected to the corresponding U-shaped pipes I 6 and the air inlet pipe 61. Hollow tubes 601 are respectively slidably installed on the inner walls of the ends of the three U-shaped pipes II 63 that coincide with the U-shaped pipes I 6 in the vertical direction. A plurality of hollow tubes 601 are respectively fixedly connected to the corresponding U-shaped pipes I 6. A plurality of U-shaped grooves 201 are respectively formed on the inner walls of both sides of the outer box 1. A plurality of rolling balls 202 are respectively rotatably installed on the inner walls of the plurality of U-shaped grooves 201. The plurality of rolling balls 202 on both sides are all slidably connected to the connecting frame 64.

[0039] By adopting a wavy pipeline design composed of three U-shaped pipes 6 and the second U-shaped pipe 63, the circulation path of hot air and the cooling area are greatly increased, thereby improving the cooling efficiency. Through the reasonable layout of the air inlet pipe 61 and the air outlet pipe 62, it is ensured that hot air can smoothly enter and exit the device, further enhancing the cooling effect. Through the fixed connection of the L-shaped rod 65 and the T-shaped column 3011, and the fixed installation of the connecting frame 64 and the second U-shaped pipe 63, the device can automatically adjust the height of the second U-shaped pipe 63 according to the change of hot air temperature. When the hot air temperature rises, the T-shaped column 3011 will push the L-shaped rod 65 and the connecting frame 64 upward, thereby driving the second U-shaped pipe 63 upward, extending the cooling path of hot air and enhancing the cooling effect. The design of the corrugated pipe 602 not only ensures the flexible connection between the first U-shaped pipe 6 and the second U-shaped pipe 63, but also prevents the leakage of coolant during the movement of the pipeline. The fixed connection of the hollow pipe 601 and the first U-shaped pipe 6, and the rotational installation of the rolling ball 202 in the U-shaped groove 201 reduce the friction between the connecting frame 64 and the inner wall of the outer box 1, making the connecting frame 64 move more smoothly during movement, reducing friction and wear, and extending the service life of the device.

[0040] The working principle and usage process of the present invention:

[0041] First, fixedly connect the air suction pipe 31 to the air outlet of the air extraction mechanism, so that hot air enters the device through the air suction pipe 31. In the initial state, the adjusting plate 5 is inclined under the support of the spring telescopic rod assembly two 501, so that hot air enters the air inlet pipe 61 through the gap formed between the adjusting plate 5 and the air inlet pipe 61 at the top, and then enters the wavy pipeline formed by the first U-shaped pipe 6 and the second U-shaped pipe 63. Since the inside of the outer box 1 and the inside of the inner box 2 are filled with coolant, the hot air is cooled when flowing inside and then discharged through the air outlet pipe 62. At the same time, since the temperature is the highest near the air inlet pipe 61 and the lowest near the air outlet pipe 62, by starting the air pump 7, the coolant at the high-temperature part is pumped through the water inlet pipe 701 and discharged through the water outlet pipe 702, so that the coolant inside the outer box 1 and the inner box 2 circulates, and then the coolant is cooled by the heat dissipation fins 101 outside the outer box 1;

[0042] When the temperature of the hot air becomes higher and higher, the airbag 4 expands when heated. Under the guidance of the funnel-shaped baffles 301 on the upper and lower sides, it extends in the upper and lower directions, thereby pushing the corresponding T-shaped columns 3011. The lower T-shaped column 3011 moves downward and contacts the adjusting plate 5. During the downward movement, it presses down the adjusting plate 5, making the gap formed by the adjusting plate 5 and the air inlet pipe 61 larger, allowing the hot air to enter for cooling faster. The upper T-shaped column 3011 moves upward, driving the L-shaped rod 65 and the connecting frame 64 to move. The connecting frame 64 drives the U-shaped pipe two 63 to move. The upward movement of the U-shaped pipe two 63 exposes the hollow pipe 601, making the pipeline for the hot air to flow longer, thereby extending the cooling time and enhancing the cooling effect. While the U-shaped pipe two 63 moves upward, the corrugated pipe 602 is stretched to prevent the coolant from entering the U-shaped pipe one 6, the hollow pipe 601, and the U-shaped pipe two 63.
