Technical Field
[0001] This utility model relates to the field of rolling mill technology, and in particular to a rolling device for high carbon steel materials. Background Technology
[0002] High-carbon steel is a metallic material with high strength and hardness, widely used in spring steel, tool steel, and high-speed moving parts. Existing high-precision rolling equipment mostly adopts a multi-roll mill structure, using a multi-layer support roll system to achieve precise control of strip thickness and tension, suitable for cold rolling of high-carbon steel materials.
[0003] In actual production, the width of high-carbon steel strip varies, and continuous rolling is often required for different specifications. The traditional integral conical intermediate roll structure has a fixed axial taper and the range of action is not adjustable, making it impossible to quickly adapt to strips of different widths. When it is necessary to change the conical action area, it is usually only possible to replace the entire intermediate roll, which is inefficient.
[0004] Therefore, a rolling device for high-carbon steel is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a rolling device for high-carbon steel materials to solve the above-mentioned problems. In actual production, the width of high-carbon steel strip varies, and continuous rolling is often required for different specifications. The traditional integral conical intermediate roll structure has a fixed axial taper and the range of action is not adjustable, which cannot quickly adapt to strips of different widths. When it is necessary to change the conical action area, the only way to achieve this is to replace the entire intermediate roll, which is inefficient.
[0006] This utility model achieves the above-mentioned objectives through the following technical solution: a rolling device for high-carbon steel materials, comprising: a rolling mill, wherein multiple drive rolls are rotatably mounted inside the rolling mill; an adjusting rolling mechanism for quickly adjusting the intermediate rolls, the adjusting rolling mechanism being disposed outside the drive rolls; wherein the adjusting rolling mechanism includes a protruding ring disposed on the surface of the drive rolls, an adjusting component disposed outside the protruding ring, and a fixing component for limiting the adjusting component disposed on the surface of the drive rolls; the adjusting rolling mechanism can quickly adjust the position of the protruding ring of the intermediate rolls through the adjusting component, and can flexibly adjust the convexity action area of the intermediate rolls according to the width of high-carbon steel strips of different specifications, avoiding the inconvenience of replacing the entire traditional integral conical intermediate roll, so that the effective pressing range of the drive rolls can be adapted to strips of different widths, improving the adaptability and efficiency in the rolling process.
[0007] Preferably, the adjustment assembly includes multiple connecting cone rings fixedly installed on both sides of the protruding ring. The shapes of the multiple connecting cone rings on the same side gradually decrease. The multiple connecting cone rings on both sides are connected to the protruding ring. The adjustment assembly can flexibly adjust the effective crown range of the intermediate roll according to the actual rolling needs. The dimensions of the multiple connecting cone rings decrease sequentially, and the installation order can be selectively configured. By replacing or reassembling the connecting cone rings and the protruding ring, rapid adjustment can be achieved, which significantly improves the production changeover efficiency.
[0008] Preferably, the protruding ring includes a first protrusion and a second protrusion. Two retaining plates are fixedly installed on one side of each of the first and second protrusions. A retaining groove is provided on the other side of each of the first and second protrusions. Both the retaining groove and the retaining plate are arc-shaped. The surface and interior of the connecting cone ring have the same structure as the protruding ring. In actual installation, the two retaining plates on one side of the protruding ring are slidably inserted into the retaining groove on the side of the adjacent connecting cone ring to complete the quick docking between the structures, which facilitates disassembly.

When the connecting block is fully inserted into the limiting groove, its T-shaped lateral edge is stuck by the inner wall of the limiting groove, thereby preventing the connecting block from sliding out in the opposite direction and ensuring a stable and reliable connection between the first protrusion and the second protrusion.
[0011] Preferably, the fixing component includes two clamping discs disposed on the surface of the drive roll. The two clamping discs are respectively located on both sides of the protruding ring and the plurality of connecting cone rings.

[0025] 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.
[0026] In practical implementation: such as Figure 1-4 As shown, a rolling apparatus for high-carbon steel includes: a rolling mill 1, with multiple drive rolls 2 rotatably mounted inside the rolling mill 1; and an adjusting rolling mechanism 3 for quickly adjusting the intermediate roll, which is located outside the drive rolls 2. The adjusting rolling mechanism 3 includes a protruding ring 31 disposed on the surface of the drive rolls 2, an adjusting component 32 disposed outside the protruding ring 31, and a fixing component 33 for limiting the adjusting component 32 disposed on the surface of the drive rolls 2. The protruding ring 31 and the adjusting component 32 form an intermediate roll. The adjusting rolling mechanism 3 can quickly adjust the position of the protruding ring 31 of the intermediate roll through the adjusting component 32. The convexity area of the intermediate roll can be flexibly adjusted according to the width of high-carbon steel strip of different specifications, avoiding the inconvenience of replacing the entire traditional integral conical intermediate roll. This allows the effective pressing range of the drive rolls 2 to adapt to strips of different widths, improving the adaptability and efficiency during the rolling process.
[0027] A rolling mill 1 typically includes basic components such as a frame body, transmission system, work roll group, intermediate roll device, tension control system, thickness detection system, and cooling and lubrication system. An adjusting rolling mechanism 3 is set on the surface of the drive roll 2 of the rolling mill 1. It consists of a protruding ring 31, an adjusting component 32, and a fixing component 33, which together form a modular and adjustable intermediate roll structure. The adjusting component 32 and its related connecting structure are set in the outer circle area of the drive roll 2, which does not affect the rotation accuracy of the roll body, the pressing stroke, and the lubrication system channel. At the same time, the fixing component 33 can provide sufficient axial limit to ensure stable operation of the structure and does not affect the original tension control of the rolling mill 1.
[0028] like Figure 3 , Figure 4 and Figure 5As shown, the adjustment assembly 32 includes multiple connecting cone rings 321 fixedly installed on both sides of the protruding ring 31. The shapes of the multiple connecting cone rings 321 on the same side gradually decrease. The multiple connecting cone rings 321 on both sides are connected to the protruding ring 31. The adjustment assembly 32 adopts a modular conical structure formed by combining multiple connecting cone rings 321 with the protruding ring 31. The effective crown range of the intermediate roll can be flexibly adjusted according to the actual rolling needs. The dimensions of the multiple connecting cone rings 321 decrease sequentially, and the installation order can be selectively configured. By replacing or reassembling the connecting cone rings 321 and the protruding ring 31, rapid adjustment can be achieved, significantly improving production changeover efficiency. The protruding ring 31 includes a first protrusion 311 and a second protrusion 312. Two clamping plates 322 are fixedly installed on one side of the first protrusion 311 and the second protrusion 312. On the other side of both protrusion 311 and protrusion 312, there is a slot 323. The slot 323 and the slot plate 322 are both arc-shaped. The surface and interior of the connecting cone ring 321 are the same as the structure of the protruding ring 31. The protruding ring 31 includes a first protrusion 311 and a second protrusion 312, which are symmetrically arranged and respectively cover and install on the outer circular surface of the drive roller 2 from the top and bottom directions. The structure of the connecting cone ring 321 is corresponding to that of the protruding ring 31. Its surface structure is the same as that of the adjacent first protrusion 311 and second protrusion 312. It is also provided with a slot plate 322 and a slot 323. In the actual installation process, by sliding and inserting the two slot plates 322 on one side of the protruding ring 31 with the slot 323 on the side of the adjacent connecting cone ring 321, the quick docking between the structures can be completed, which is convenient for disassembly.
[0029] Two connecting blocks 326 are fixedly installed at the bottom of the first protrusion 311, and two entry grooves 324 are formed on the surface of the second protrusion 312. The first protrusion 311 and the second protrusion 312 are quickly connected and assembled through the connecting blocks 326 and the entry grooves 324, which facilitates the quick connection of the protruding ring 31. The second protrusion 312 has a limiting groove 325 inside, which is connected to the entry groove 324. The entry groove 324 and the limiting groove 325 are set in an L shape, and the connecting block 326 is set in a T shape. During the assembly process, the connecting block 326 is first inserted into the entry groove 324 in the vertical direction, and then slides along the direction of the limiting groove 325, and finally embedded into the inside of the limiting groove 325 to form a structural lock. When the connecting block 326 is fully inserted into the limiting groove 325, its T-shaped lateral edge is stuck by the inner wall of the limiting groove 325, thereby preventing the connecting block 326 from sliding out in the opposite direction and ensuring that the connection between the first protrusion 311 and the second protrusion 312 is stable and reliable.
[0030] like Figure 2 , Figure 3 and Figure 5As shown, the fixing component 33 includes two clamping discs 331 disposed on the surface of the drive roll 2. The two clamping discs 331 are respectively located on both sides of the protruding ring 31 and the multiple connecting conical rings 321. The two clamping discs 331 act on both ends of the intermediate roll structure component, including the protruding ring 31 and the multiple connecting conical rings 321, to form axial limiting, which can ensure the stable use of the intermediate roll. A threaded tube 332 is fixedly installed on one side of the clamping disc 331. The outer sides of the two threaded tubes 332 are threadedly connected to the same limiting ring 333. The clamping disc 331 is composed of a detachable two semi-circular ring structure. The two semi-circular ring structures are joined together by the threaded tubes 332 to form a closed state, and are quickly locked by the same limiting ring 333, ensuring that the clamping disc 331 is installed firmly and fixing the intermediate roll.
[0031] A rolling method for high carbon steel materials
[0032] A1. The adjusting rolling mechanism 3 can quickly adjust the position of the protruding ring 31 of the intermediate roll through the adjusting component 32. The convexity action area of the intermediate roll can be flexibly adjusted according to the width of high carbon steel strip of different specifications, avoiding the inconvenience of replacing the entire traditional integral conical intermediate roll. This allows the effective pressing range of the drive roll 2 to be adapted to strips of different widths, improving the adaptability and efficiency in the rolling process.
[0033] A2. The clamping disc 331 is composed of a detachable two-half-ring structure. The two half-ring structures are joined together by the threaded tube 332 to form a closed state, and are quickly locked by the same limiting ring 333 to ensure that the clamping disc 331 is installed firmly and to fix the intermediate roller.
[0034] In use, this invention allows for rapid assembly and connection of structures by sliding the two retaining plates 322 on one side of the protruding ring 31 into the retaining grooves 323 on the side of the adjacent connecting cone ring 321. This modular combination of the intermediate roller structure facilitates subsequent disassembly and maintenance. Multiple connecting cone rings 321 combined with the protruding ring 31 form a modular conical structure. The outer diameter of each connecting cone ring 321 decreases sequentially. The installation sequence can be selectively configured according to different strip widths and crown requirements. By replacing or recombining the connecting cone rings 321, the effective crown of the intermediate roller can be flexibly adjusted. The range significantly improves the efficiency and adaptability of production switching. During assembly, the first protrusion 311 is first inserted vertically into the entry groove 324 on the surface of the second protrusion 312 via the connecting block 326 at its lower part. Then, it slides along the direction of the L-shaped limiting groove 325 and finally embeds into the inside of the limiting groove 325. The T-shaped structure design of the connecting block 326 allows its lateral edge to be effectively locked by the inner wall of the limiting groove 325, forming a reliable structural lock to prevent the connecting block 326 from slipping off in the opposite direction during operation, ensuring a stable and reliable connection between the first protrusion 311 and the second protrusion 312.
[0035] In addition, the fixing disc 331 is composed of a detachable two-half-ring structure. The two half-rings are joined together by the threaded tube 332 to form a complete circular structure, and are tightened and locked by the same limiting ring 333. This structure is not only easy to install and accurately positioned, but also ensures that the fixing disc 331 is firmly installed on the surface of the drive roll 2, and forms effective axial compression and limiting on the protruding ring 31 and the connecting cone ring 321, further improving the stability and reliability of the entire intermediate roll module structure.
[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
