Description

Technical Field

[0001] This utility model relates to the field of rolling equipment technology, specifically a modular rolling mill with a double movable baffle plate, a water seal device, and a modular rolling mill. Background Technology

[0002] To reduce roll wear and extend the steel throughput and overall service life of the rolls, steel rolling mills generally use high-pressure, high-volume forced water cooling to cool the rolls. When high-pressure, high-volume cooling water is sprayed onto the rotating rolls, some of the cooling water will splash up; the cooling water that splashes outside the rolling passage not only affects the cleanliness of the production environment, but also makes the work area slippery, posing a safety hazard of slipping and falling.

[0003] like Figure 1 As shown, the existing water seal device of the modular rolling mill includes a movable baffle plate 7 and a fixed baffle plate 3 arranged vertically. The movable baffle plate 7 is located in front of or behind the roll box 5 and can slide on the slide rail 4 of the fixed baffle plate. When replacing the roll box 5, roll ring, and guide 6, the movable baffle plate 7 needs to be pulled upwards, and after replacement, it should be inserted back into the slide rail 4 to reset. See also Chinese patent document CN222766956U, published on April 18, 2025, entitled "A Novel Modular Finishing Mill Installation Structure".

[0004] like Figure 2 As shown, the existing movable baffle 7 is an integral structure, which has the following problems: First, it is heavy and requires two people to pull it out or to use an overhead crane to lift it out when replacing it, which takes a long time; second, the efficiency of replacing the roller ring and guide is low, which directly shortens the effective production time; third, the movable baffle 7 is pulled out at a high height, which further increases the difficulty of operation.

[0005] Explanation of the name:

[0006] Modular rolling mill: A specialized metal rolling equipment based on a modular design concept. Its core is the design of key functional units such as roll assemblies, transmission systems, control modules, and roll boxes as independent, combinable "modules." Through the flexible combination, rapid replacement, and collaborative operation of different modules, it achieves efficient rolling and forming of various metal materials such as steel and non-ferrous metals. It is an important piece of equipment in modern steel rolling production for improving efficiency, flexibility, and product quality.

[0007] Water seal device: A protective structure used in the rolling mill operation process. Its main function is to effectively block cooling water, emulsions, and other liquids generated in the rolling area, preventing liquids from splashing onto critical components of the rolling mill such as the transmission system and electrical control system, as well as the surrounding working environment, thus ensuring the stable operation of the rolling mill and the safety of operators. Utility Model Content

[0008] To address the problem of inconvenient disassembly and assembly of movable baffles in existing modular rolling mills, this utility model provides a double movable baffle, a water seal device, and a modular rolling mill. The structure of the double movable baffle of the modular rolling mill is optimized to a double movable baffle structure, which improves the operational efficiency and convenience when replacing roller rings and guides, reduces equipment maintenance time, and thus improves the overall efficiency of the production line.

[0009] The technical solution adopted by this utility model embodiment to solve its technical problem is:

[0010] A dual movable baffle for a modular rolling mill includes a small movable baffle and a large movable baffle. The large movable baffle has a large movable plate body and an installation notch. The large movable plate body has a U-shaped structure and includes a left movable plate segment, a lower movable plate segment, and a right movable plate segment connected sequentially from left to right. The left movable plate segment, the lower movable plate segment, and the right movable plate segment surround the installation notch. The small movable baffle can completely close the installation notch. The small movable baffle and the large movable baffle are detachably connected.

[0011] The small movable baffle plate is inserted into the large movable baffle plate; when the small movable baffle plate moves upward relative to the large movable baffle plate, the small movable baffle plate can disengage from the installation notch; when the small movable baffle plate moves downward relative to the large movable baffle plate, the small movable baffle plate can be inserted into the installation notch.

[0012] The large movable baffle also contains two strip pressure plates, both of which are U-shaped structures. The two strip pressure plates are located on the left, lower, and right sides of the installation notch, and are spaced apart. The large movable baffle body is located between the two strip pressure plates, and is stacked and fixed to the two strip pressure plates. A first insertion groove is formed between the two strip pressure plates and the large movable baffle body, and the edge of the small movable baffle can be matched and inserted into the first insertion groove of the large movable baffle body.

[0013] Both the upper ends of the left and right movable plate sections are fixedly connected to external end tubes, which extend in the left and right directions. The outer diameter of the external end tubes is greater than the thickness of the large movable plate body.

[0014] The small movable baffle includes a small movable plate body and a baffle. The baffle is located on the front or rear side of the small movable plate body and is fixed to the left, lower, and right edges of the small movable plate body. The cross-section of the baffle is L-shaped. A second insertion groove is formed between the baffle and the small movable plate body. When the edge of the small movable baffle is properly inserted into the first insertion groove of the large movable baffle, the edge of a strip-shaped pressure plate can be properly inserted into the second insertion groove.

[0015] An inner tube is fixedly connected to the upper end of the small movable plate. The inner tube extends in the left and right direction, and its outer diameter is greater than the thickness of the small movable plate.

[0016] The small movable baffle also includes a handle. When the baffle is located on the front side of the small movable baffle, the handle is fixed to the rear side of the small movable baffle; when the baffle is located on the rear side of the small movable baffle, the handle is fixed to the front side of the small movable baffle.

[0017] The area of ​​the installation notch is 45% to 85% of the area of ​​the large movable baffle, and the weight of the small movable baffle is 75% to 125% of the weight of the large movable baffle.

[0018] A water seal device for a modular rolling mill includes a fixed baffle plate and a double movable baffle plate of the modular rolling mill. The double movable baffle plate and the fixed baffle plate are arranged vertically, with the lower end of the larger movable baffle plate overlapping the upper end of the fixed baffle plate.

[0019] A modular rolling mill includes a slide rail and the aforementioned water seal device. The slide rail is in an upright position and is located on the left and right sides of the double movable baffle of the modular rolling mill. The left and right sides of the large movable baffle are matched and inserted into the slide rail.

[0020] The beneficial effects of this utility model embodiment are:

[0021] 1. Improve the efficiency of high-frequency operation: When changing the roller ring and guide (which requires frequent operation when changing rolling specifications), only a small movable baffle (weighing about 26 kg) needs to be operated, and the extraction height is reduced, which can be easily operated by a single person, effectively avoiding the loss of production efficiency.

[0022] 2. No impact on routine maintenance schedule: The routine maintenance cycle for the roller box is 5-6 months. The time required to lift out the double movable baffles during maintenance is short and will not affect normal production.

[0023] 3. Enhanced adaptability: Compared to traditional single-moving baffles, the dual-moving structure can flexibly match two maintenance needs: "high-frequency light load" (roller changing ring / guide) and "low-frequency heavy load" (roller changing box), significantly improving operational flexibility.

[0041] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the dual movable baffle of the modular rolling mill in this embodiment includes a small movable baffle 1 and a large movable baffle 2. The large movable baffle 2 contains a large movable plate body 21 and an installation notch 22. The large movable plate body 21 has a U-shaped structure and contains a left movable plate segment 211, a lower movable plate segment 212 and a right movable plate segment 213 connected from left to right. The left movable plate segment 211, the lower movable plate segment 212 and the right movable plate segment 213 form the installation notch 22. The small movable baffle 1 can completely close the installation notch 22. The small movable baffle 1 and the large movable baffle 2 are detachably connected.

[0042] There are several ways to achieve a detachable connection between the small movable baffle 1 and the large movable baffle 2. For example, the small movable baffle 1 and the large movable baffle 2 can be inserted together, allowing the small movable baffle 1 to move relative to the large movable baffle 2 in the up-down, left-right, or front-back directions; that is, the insertion and removal directions of the small movable baffle 1 can be up-down, left-right, or front-back directions. Alternatively, the small movable baffle 1 and the large movable baffle 2 can be connected by a hinge, allowing the small movable baffle 1 to rotate left, right, or downward relative to the large movable baffle 2. Or, the small movable baffle 1 and the large movable baffle 2 can be connected by screws or pins, etc.

[0043] Preferred, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the small movable baffle 1 is inserted into the large movable baffle 2; when the small movable baffle 1 moves upward relative to the large movable baffle 2, the small movable baffle 1 can disengage from the installation notch 22, and the disassembly direction of the small movable baffle 1 is from bottom to top; when the small movable baffle 1 moves downward relative to the large movable baffle 2, the small movable baffle 1 can be inserted into the installation notch 22, and the installation direction of the small movable baffle 1 is from top to bottom.

[0044] The large movable baffle 2 also includes two strip pressure plates 23, both of which are U-shaped. The two strip pressure plates 23 are located on the left, lower, and right sides of the installation notch 22, and are spaced apart. The large movable plate body 21 is located between the two strip pressure plates 23. The large movable plate body 21 and the two strip pressure plates 23 are connected and fixed by bolts and nuts. A first insertion groove 24 is formed between the two strip pressure plates 23 and the large movable plate body 21. The first insertion groove 24 is U-shaped. The left, lower, and right edges of the small movable baffle 1 can be matched and inserted into the first insertion groove 24 of the large movable baffle 2.

[0045] The left movable plate segment 211 and the right movable plate segment 213 are symmetrical and mirror images of each other. The upper ends of the left movable plate segment 211 and the upper ends of the right movable plate segment 213 are fixedly connected to the outer end tubes 25. The two outer end tubes 25 are symmetrical and mirror images of each other. The outer end tubes 25 extend in the left and right direction. The outer diameter of the outer end tubes 25 is greater than the thickness of the large movable plate body 21.

[0046] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the small movable baffle 1 includes a small movable plate body 11 and a baffle 12. The baffle 12 is located on the front or rear side of the small movable plate body 11. The baffle 12 is fixed to the left edge, lower edge and right edge of the small movable plate body 11. The cross-section of the baffle 12 is L-shaped. A second insertion groove 13 is formed between the baffle 12 and the small movable plate body 11. When the edge of the small movable baffle 1 is inserted into the first insertion groove 24 of the large movable baffle 2, the edge of a strip pressure plate 23 can be inserted into the second insertion groove 13. The double insertion can ensure sliding stability and water-blocking sealing.

[0047] like Figure 3 As shown, an inner end tube 14 is fixedly connected to the upper end of the small movable plate 11. The inner end tube 14 extends in the left-right direction, and its outer diameter is larger than the thickness of the small movable plate 11. The thickness of the small movable plate 11 is basically the same as the thickness of the large movable plate 21. The small movable plate 11 and the large movable plate 21 can be located in the same vertical plane. The outer diameter of the inner end tube 14 and the outer diameter of the outer end tube 25 can be the same, and the axis of the inner end tube 14 and the axis of the outer end tube 25 can coincide.

[0048] like Figure 7 , Figure 8As shown, the small movable baffle 1 also includes a handle 15. When the baffle 12 is located on the front side of the small movable baffle 11, the handle 15 is fixed to the rear side of the small movable baffle 11; when the baffle 12 is located on the rear side of the small movable baffle 11, the handle 15 is fixed to the front side of the small movable baffle 11.

[0049] like Figure 9 As shown, the area of ​​the installation notch 22 is 45% to 85% of the area of ​​the large movable baffle 2. For example, the area of ​​the installation notch 22 is L1×W1, and the area of ​​the large movable baffle 2 is L2×W2. The weight of the small movable baffle 1 is 75% to 125% of the weight of the large movable baffle 2, and the weight of the small movable baffle 1 can be 20kg to 30kg.

[0050] The following describes a water seal device for a modular rolling mill. The water seal device includes a fixed baffle plate 3 and the aforementioned double movable baffle plate of the modular rolling mill. The double movable baffle plate and the fixed baffle plate 3 of the modular rolling mill are arranged vertically, and the lower end of the large movable plate 21 overlaps with the upper end of the fixed baffle plate 3.

[0051] The following describes a modular rolling mill, which includes a slide rail 4 and the water seal device of the modular rolling mill described above. The slide rail 4 is in an upright state and is located on the left and right sides of the double movable baffle of the modular rolling mill. The left and right sides of the large movable plate 21 are matched and inserted into the slide rail 4.

[0052] The modular rolling mill includes two water seal devices as described above, which are arranged at an interval. The side 12 of the small movable baffle 1 faces the roll box 5, and the handle 15 of the small movable baffle 1 faces away from the roll box 5. For example, the side 12 of the front water seal device is located on the rear side of the small movable plate 11, and the handle 15 is fixed to the front side of the small movable plate 11; the side 12 of the rear water seal device is located on the front side of the small movable plate 11, and the handle 15 is fixed to the rear side of the small movable plate 11.

[0053] The main inventive point of this utility model lies in the improvement of the structure of the movable baffle 7. It can also be understood that the difference between this utility model and the prior art is that the movable baffle 7 of the modular rolling mill is replaced by the double movable baffle of the modular rolling mill. Except for the double movable baffle, the other technical features of the modular rolling mill described in this utility model are the same as those in the prior art.

[0054] The following describes the double movable baffle, water seal device, and working process of the modular rolling mill.

[0055] When the modular rolling mill is in normal working condition, both the small movable baffle 1 and the large movable baffle 2 are in the lower limit position, and both are in the installation state.

[0056] When replacing the roller ring and guide 6: simply pull the small movable baffle 1 upwards, while keeping the large movable baffle 2 in the same position. Figure 4 As shown, after completing the operation and replacing the roller ring and guide 6, insert the small movable baffle 1 back into place to reset.

[0057] When replacing roller box 5: Pull out or lift out the small movable baffle 1 and the large movable baffle 2 as a whole along the slide rail 4, such as... Figure 5 As shown, after the roller box 5 is overhauled, the small movable baffle 1 and the large movable baffle 2 are reset as a whole.

[0058] The traditional single-movable baffle has been optimized into a double-movable baffle structure, comprising a small movable baffle 1 and a large movable baffle 2. Both the small movable baffle 1 and the large movable baffle 2 can be operated independently, which is the core of the efficiency improvement. An independent small movable baffle 1 is designed for high-frequency operations (roller ring / guide replacement), significantly reducing operational difficulty and time consumption, and directly increasing the effective operating time of the production line. The double-movable baffle structure can be used for both roller ring / guide replacement and roller box replacement scenarios, balancing operational convenience and equipment maintenance needs, thus broadening its applicability.

[0059] The above description is merely a specific embodiment of this utility model and should not be construed as limiting the scope of its implementation. Therefore, any substitution of equivalent components or equivalent changes and modifications made within the scope of protection of this utility model should still fall within its coverage. Furthermore, the technical features, technical solutions, and embodiments of this utility model can be freely combined and used.
