Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of roll processing technology, and more specifically, to an auxiliary tooling for water quenching of rolls. Background Technology
[0002] In the field of metal rolling, rolls are the core components for realizing continuous plastic deformation of metals. Their performance and quality are directly related to the precision, surface quality and production efficiency of rolled products. As steel rolling technology moves towards larger scale, higher speed and higher precision, extremely stringent requirements are placed on the quality and performance of rolls.
[0003] During operation, rolling mill rolls must withstand enormous rolling forces, frictional forces, and alternating thermal stresses, resulting in extremely harsh service conditions. To meet these complex working conditions, rolling mill roll materials are mostly selected from chilled cast iron, cast steel, forged steel, alloy steel, and even ductile iron and cemented carbide. Heat treatment processes, especially quenching, are key means to improve the overall performance of rolling mill rolls. Through quenching, the microstructure of the rolling mill rolls can be optimized, enhancing its hardness, wear resistance, strength, and toughness, ensuring stable operation in high-intensity rolling processes and extending its service life.
[0004] Traditional water quenching operations for rolling mill rolls face numerous challenges. On the one hand, the rolls are large and heavy, making it difficult to achieve precise positioning and stable support during quenching. If the rolls shift or sway in the quenching liquid, it will cause uneven cooling, resulting in local hardness differences, which will seriously affect the quality of the rolls and increase the scrap rate. On the other hand, the rolls need to be heated evenly during quenching. Traditional methods cannot ensure that all parts of the rolls are in full and uniform contact with the quenching liquid. At the same time, the rolls are prone to internal stress due to thermal expansion and contraction during quenching. If not handled properly, this can lead to defects such as roll deformation and cracking, which will greatly reduce the performance and reliability of the rolls.
[0005] Furthermore, with the booming development of the steel rolling industry, higher requirements have been placed on the production efficiency of rolls. Traditional quenching processes are cumbersome and inefficient, making it difficult to meet the needs of large-scale, high-efficiency production. Moreover, different types and sizes of rolls have different quenching processes, requiring a flexible and adjustable auxiliary tooling to adapt to the diverse quenching needs of rolls. Against this backdrop, it is urgent to develop an auxiliary tooling that can stably support and accurately position rolls, and achieve uniform quenching and efficient operation. The roll water quenching auxiliary tooling has emerged to address this need. Its components work together to solve the problems in traditional quenching processes, providing strong support for improving the quenching quality and production efficiency of rolls. Utility Model Content
[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide an auxiliary tooling for water quenching of rolls, which solves the many challenges faced by traditional water quenching operations of rolls in the prior art. On the one hand, rolls are large in size and have considerable weight, making it difficult to achieve precise positioning and stable support during the quenching process. If the rolls are offset or shake in the quenching liquid, it will cause uneven quenching and cooling, resulting in local hardness differences, which seriously affects the quality of the rolls.
[0007] According to one aspect, at least one embodiment of this disclosure provides an auxiliary tooling for water quenching of rolling mill rolls, comprising:
[0008] A placement platform, wherein a supporting frame is provided on the upper surface of the placement platform;
[0009] A roll support assembly, wherein the roll support assembly is disposed on the mounting platform;
[0010] A support drive assembly is disposed on the support frame;
[0011] The roll support assembly includes a V-shaped plate, which is disposed on the support frame. The V-shaped plate has a positioning groove. An inner support frame is disposed between the V-shaped plate and the mounting platform. The inner support frame is evenly distributed at the four corners of the V-shaped plate. There are two V-shaped plates, and a spacer cavity is formed between the two V-shaped plates.
[0012] As a further technical solution, the side wall of the support frame is provided with a deep plate, and the end of the deep plate is provided with a mounting frame. The mounting frame is located on the side wall of the mounting platform, and the mounting frame is welded and fixed to the deep plate.
[0013] As a further technical solution, the support drive assembly includes a pin connecting buckle, a flipping frame connected to the pin connecting buckle, a connecting frame at the end of the flipping frame, a wheel sleeve at the end of the connecting frame, and a support wheel inside the wheel sleeve.
[0014] As a further technical solution, the flipping frame has an insertion hole, and an insertion shaft is provided inside the insertion hole. The lower end of the insertion shaft is inserted into the interior of the support frame.
[0015] As a further technical solution, the V-shaped plate is provided with a positioning port, and there are two support wheels located on both sides of the V-shaped plate. The flipping frame flips into the interior of the positioning port.
[0016] As a further technical solution, the opposite side walls of the support frame are provided with lifting hooks, and the lower end of the lifting hook is provided with a clearance frame, which is inclined.
[0017] As a further technical solution, the opposite side walls of the mounting platform are provided with lifting rings, and the number of lifting rings is several, with multiple lifting rings evenly arranged on the side walls of the mounting platform.
[0018] As a further technical solution, the structure of the deep plate is the same as that of the V-shaped plate, but the height of the deep plate is lower than that of the V-shaped plate.
[0019] The beneficial effects of the embodiments disclosed herein are as follows:
[0020] 1. In this disclosure, the auxiliary tooling can accurately position the roll through the V-shaped plate and positioning groove of the roll support assembly. At the same time, the spacer cavity formed by the two V-shaped plates can stably support the roll. In conjunction with the support wheel of the support drive assembly, it can effectively prevent the roll from shifting position or shaking during the quenching process. This allows all parts of the roll to be evenly contacted with the quenching liquid when the roll is immersed in water quenching, avoiding local hardness differences caused by uneven cooling. It can effectively reduce defects such as roll deformation and cracking caused by improper quenching process, greatly improve the uniformity of the roll's microstructure, thereby enhancing the roll's hardness, wear resistance, strength and toughness, and significantly improving the overall quality and performance reliability of the roll.
[0021] 2. In this disclosure, the support drive assembly of the tooling can be flexibly adjusted in position by driving the support wheels through the flipping frame, which can adapt to the quenching requirements of different types and sizes of rolls. In actual production, operators do not need to frequently change the tooling structure. They can quickly complete the positioning and support adjustment of different rolls with simple operations, which greatly shortens the tooling debugging time. At the same time, the support wheels can drive the rolls to rotate under external power, which accelerates the heat exchange efficiency between the roll surface and the quenching liquid during the quenching process and shortens the quenching time. In addition, the design of the tooling's lifting ring and lifting hook, together with the lifting equipment, realizes the rapid lifting and transfer of the tooling and the rolls, effectively improving the overall production efficiency of roll quenching and meeting the large-scale and high-efficiency production needs of the steel rolling industry.

[0034] like Figures 1-4 As shown, it illustrates an auxiliary tooling for water quenching of rolling mill rolls according to this disclosure, comprising:
[0035] The placement platform 1 has a supporting frame 2 installed on its upper surface;
[0036] Roll support assembly 3 is mounted on mounting platform 1;
[0037] Support drive assembly 4 is mounted on support frame 2;
[0038] The roll support assembly 3 includes a V-shaped plate 3-1, which is set on the support frame 2. The V-shaped plate 3-1 has a positioning groove 3-2. A support inner frame 3-3 is set between the V-shaped plate 3-1 and the mounting platform 1. The support inner frame 3-3 is evenly distributed at the four corners of the V-shaped plate 3-1. There are two V-shaped plates 3-1, and a spacer cavity 3-4 is formed between the two V-shaped plates 3-1.
[0039] The support drive assembly 4 includes a pin connecting buckle 4-1, a flipping frame 4-2 connected to the pin connecting buckle 4-1, a connecting frame 4-3 at the end of the flipping frame 4-2, a wheel sleeve 4-4 at the end of the connecting frame 4-3, and a support wheel 4-5 inside the wheel sleeve 4-4.
[0040] In some examples, the mounting platform 1 is the basic load-bearing component of the entire auxiliary tooling, providing an installation platform for other components such as the support frame 2 and the roll support assembly 3, ensuring the stability of the tooling during use. The frame structure of the support frame 2 is made of high-strength steel and processed through cutting and welding. Deep plates 3-5 are welded to the side walls of the support frame 2, and mounting frames 3-6 are welded to the ends of the deep plates 3-5. The mounting frames 3-6 are welded to the side walls of the mounting platform 1, forming a stable triangular support structure to enhance the stability of the support frame 2. Steel plates of appropriate thickness are selected and formed into V-shaped structures through stamping or machining. Positioning grooves 3-2 are opened on the surface of the V-shaped plates, the shape and size of which are adapted to the outer contour of the roll. Inner support frames 3-3 are welded at the four corners of the V-shaped plates. The inner support frames 3-3 are made of square steel pipes, and during welding, it is ensured that the inner support frames 3-3 are evenly distributed and perpendicular to the surface of the V-shaped plates. Two V-shaped plates are made and installed on the support frame 2, so that the two V-shaped plates... A spacer cavity 3-4 is formed between the V-shaped plates. The width of the spacer cavity 3-4 is adjusted according to the length of the roll. The V-shaped plate is used to support and position the roll. Its V-shaped structure can fit tightly against the outer surface of the roll. The positioning groove 3-2 further restricts the movement of the roll, ensuring that the roll maintains a stable position during quenching and preventing the roll from shifting or rolling, thus ensuring the uniformity of the quenching effect. The inner support frame 3-3 enhances the load-bearing capacity and stability of the V-shaped plate, enabling it to withstand the weight of the roll and various forces during the quenching process. The deep plate 3-5 is processed according to the manufacturing process of the V-shaped plate, so that its structure is the same as that of the V-shaped plate, but the height of the deep plate 3-5 is controlled to be lower than that of the V-shaped plate. The height of the forming plate is determined by installing the processed deep plate 3-5 at the corresponding position on the side wall of the support frame 2 and fixing it by welding or other methods. The pin connecting buckle 4-1 is made using machining equipment. Its structure includes a buckle body and a pin hole. The pin connecting buckle 4-1 is installed at the designated position of the support frame 2 and fixed by bolts or welding to ensure a firm connection. The pin connecting buckle 4-1 serves as a connecting component of the flipping frame 4-2 and is used to achieve the hinge between the flipping frame 4-2 and the support frame 2, so that the flipping frame 4-2 can be flexibly flipped around the pin, thereby facilitating the adjustment of the position of the support wheel 4-5 to adapt to rolls of different sizes and shapes.
[0041] Fabricate and process the tilting frame 4-2. A through hole 4-6 is made on the tilting frame 4-2, the size of which matches the through shaft 4-7. A pin is installed at one end of the tilting frame 4-2, and the pin is hinged to the pin connecting buckle 4-1. A connecting frame 4-3 is welded to the end of the tilting frame 4-2. The tilting frame 4-2 is a key transmission component supporting the drive assembly 4. Its tilting action drives the connecting frame 4-3 and the support wheel 4-5 to move. The connecting frame 4-3 is fabricated according to design requirements. One end is welded and fixed to the end of the tilting frame 4-2, and the other end is used to install the wheel sleeve 4-4. The connecting frame 4-3 connects the tilting frame 4-2 and the wheel sleeve 4-4, transmitting the tilting action of the tilting frame 4-2 to the wheel sleeve 4-4 and the support wheel 4-5. It also provides mounting support for the wheel sleeve 4-4 and the support wheel 4-5, ensuring that the support wheel 4-5 can... The support wheel 4-5 is stably in contact with the roll surface, providing support and drive for the roll. The sleeve 4-4 is machined to match its internal dimensions, ensuring the support wheel 4-5 can rotate freely within it. The support wheel 4-5 is then installed inside the sleeve 4-4, which is then mounted at the end of the connecting frame 4-3. A secure connection is ensured using bolts or other fixing methods. The support wheel 4-5 directly contacts the roll surface, providing auxiliary support during quenching, sharing the roll's weight, and preventing deformation due to its own weight. Simultaneously, external power drives the support wheel 4-5 to rotate, which in turn drives the roll, ensuring uniform heating during quenching and improving quenching quality. The sleeve 4-4 protects and supports the support wheel 4-5, ensuring its rotational flexibility and stability.
[0042] like Figures 1-4 As shown, in this embodiment, a deep plate 3-5 is provided on the side wall of the support frame 2, and a mounting frame 3-6 is provided at the end of the deep plate 3-5. The mounting frame 3-6 is provided on the side wall of the mounting platform 1, and the mounting frame 3-6 is welded and fixed to the deep plate 3-5.
[0043] In some examples, the deep plate 3-5 assists in supporting the support frame 2 to enhance the overall structural strength. Without affecting the placement and support of the rolls, it provides additional support force for the support frame 2, improving the stability of the tooling when bearing the rolls. Especially during operations such as water quenching, it can effectively disperse stress and prevent the support frame 2 from deforming.
[0044] The support frame 2 serves as the main support structure of the tooling, used to install the roll support assembly 3 and the support drive assembly 4, providing them with stable support points. The deep plate 3-5 and the mounting frame 3-6 on the side wall further enhance the stability of the support frame 2, ensuring that it will not shake or tilt when carrying the roll and performing quenching operations.
[0045] For example, such as Figure 3As shown, the flipping frame 4-2 has an insertion hole 4-6, and an insertion shaft 4-7 is provided inside the insertion hole 4-6. The lower end of the insertion shaft 4-7 is inserted into the interior of the support frame 2.
[0046] In some examples, when the rolls need to be supported or driven, the flipping frame 4-2 is flipped so that the support wheel 4-5 contacts the roll surface; when not in use, the flipping frame 4-2 can be flipped back to its original position to avoid interference with other operations. The insertion hole 4-6 cooperates with the insertion shaft 4-7 to limit the flipping angle of the flipping frame 4-2 and ensure the stability and accuracy of the flipping process.
[0047] For example, such as Figure 1 As shown, the V-shaped plate 3-1 is provided with a positioning port 5, and there are two support wheels 4-5. The two support wheels 4-5 are located on both sides of the V-shaped plate 3-1, and the flipping frame 4-2 flips into the interior of the positioning port 5.
[0048] In some examples, the positioning port 5 is used to position the roll after it has been placed, and a portion of the roll can be embedded into the positioning port 5 to fix it in place.
[0049] For example, such as Figure 1 As shown, lifting hooks 6 are provided on the opposite side walls of the support frame 2, and a relief frame 7 is provided at the lower end of the lifting hooks 6. The relief frame 7 is inclined.
[0050] In some examples, lifting hooks 6 are installed on the opposite side walls of the support frame 2, and inclined clearance frames 7 are welded to the lower end of the hooks. At the same time, mounting holes are reserved on the support frame 2 for installing components such as the through shafts 4-7 of the support drive assembly 4. The lifting hooks 6 and clearance frames 7 work together with the lifting equipment to provide clearance space for lifting tools such as wire ropes during the lifting process, preventing interference with other parts of the tooling during the lifting process and ensuring the smooth progress of the lifting operation.
[0051] For example, such as Figure 1 As shown, the opposite side walls of the mounting platform 1 are provided with lifting rings 8, and there are several lifting rings 8, which are evenly arranged on the side walls of the mounting platform 1.
[0052] In some examples, the lifting ring 8 is used in conjunction with lifting equipment to enable the overall movement and positioning of the tooling, facilitating the transportation of the tooling and rolls to working areas such as the quenching water tank.
[0053] For example, such as Figure 1 As shown, the structure of the deep plate 3-5 is the same as that of the V-shaped plate 3-1, but the height of the deep plate 3-5 is lower than that of the V-shaped plate 3-1.
[0054] When in use, the mounting platform 1 serves as the basic load-bearing component of the entire tooling, providing a stable installation platform for other components. Its horizontal and robust structure ensures the stability of the tooling during use, preventing the rolls from shaking or shifting during the quenching process due to an unstable foundation. The support frame 2 is installed on the mounting platform 1, and the triangular support structure formed by the deep plate 3-5 and the mounting frame 3-6 further enhances the overall stability and load-bearing capacity.
[0055] The V-shaped plates in the roll support assembly 3 play a crucial positioning role. The spacer cavity 3-4 formed by the two V-shaped plates is used to place the roll. The V-shaped structure of the V-shaped plates fits tightly against the outer surface of the roll. At the same time, the positioning groove 3-2 is adapted to the shape of the two ends of the roll, restricting the movement of the roll from multiple directions, so that the roll always maintains a fixed position during the quenching process, ensuring the accuracy and consistency of quenching. The inner support frame 3-3 is evenly distributed at the four corners of the V-shaped plates, enhancing the load-bearing strength of the V-shaped plates, enabling them to withstand the weight of the roll and various external forces during the quenching process.
[0056] The support drive assembly 4 is the core component for achieving stable support and rotation of the roll. The pin connecting buckle 4-1 hinges the tilting frame 4-2 to the support stand 2, allowing the tilting frame 4-2 to tilt flexibly. When support is needed for the roll, the operator tilts the tilting frame 4-2, so that the support wheel 4-5 at the end of the connecting frame 4-3 contacts the roll surface. The through shaft 4-7 engages with the through hole 4-6 on the tilting frame 4-2, limiting the tilting angle of the tilting frame 4-2 and ensuring that the support wheel 4-5 accurately reaches the predetermined position and contacts the roll with appropriate pressure. After the support wheel 4-5 contacts the roll surface, it shares the weight of the roll, preventing the roll from deforming due to its own weight. On the other hand, it drives the support wheel 4-5 to rotate through an external power source (such as a motor). Due to the friction between the support wheel 4-5 and the roll surface, the roll rotates synchronously. During the water quenching process, the rotation of the roll ensures that all parts of it contact the quenching medium evenly, avoiding local overheating or overcooling and ensuring the uniformity and stability of the quenching quality.
[0057] The lifting ring 8 on the side wall of the mounting platform 1 and the lifting hook 6 on the support frame 2, together with the lifting equipment (such as cranes, overhead cranes, etc.), enable the overall movement of the tooling and the roll. After the tooling is assembled, it can be lifted to the position of the roll to be quenched through the lifting ring 8. After the roll is placed on the V-shaped plate and the support drive assembly 4 is adjusted, the tooling together with the roll is lifted to the top of the quenching water tank using the lifting hook 6. The clearance frame 7, which is inclined at the lower end of the lifting hook 6, provides clearance space for lifting tools such as wire ropes during the lifting process, preventing interference between the lifting tools and other parts of the tooling, and ensuring the safety and smooth progress of the lifting process. In this way, the tooling can move flexibly between different working areas to meet the process requirements of the roll quenching process. Through the coordinated work of the above components, the roll quenching auxiliary tooling achieves precise control of the entire process of the roll from positioning, support, drive to lifting and movement, effectively ensuring the smooth implementation of the roll quenching process and the improvement of quenching quality.
