Description

Technical Field

[0001] This utility model belongs to the technical field of finishing mills, specifically relating to a disassembly and assembly tooling. Background Technology

[0002] The CVC (Current Controlled Variable Valve) in the finishing mill of a hot rolling mill consists of multiple curved roll blocks used to adjust and control the cross-sectional profile and shape of the strip. Each CVC unit in a mill stand weighs approximately 20 tons, with the weight of a single operating side curved roll block and a single drive side curved roll block weighing approximately 5.5 tons and 4.34 tons respectively. The multiple curved roll blocks are individually secured to the mill stand with screws. When the overall accuracy of the CVC in a mill stand decreases or oil leakage occurs at the back end of a single curved roll block, the curved roll block must be disassembled for repair.

[0003] In existing technologies, due to the heavy weight of individual curved roller blocks, they need to be hoisted by overhead cranes after disassembly. However, since there are cable trays and safety platforms above the hoisting location of the curved roller blocks, it is unavoidable to use a risky operation method of slanted pulling and lifting, which poses a high safety hazard. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned deficiencies in the existing technology by providing a disassembly and assembly tooling. The disassembly and assembly tooling effectively solves the safety hazards of hoisting during the disassembly and assembly of the bending roll blocks of the finishing mill and improves the maintenance efficiency.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A disassembly and assembly fixture for disassembling and assembling bent roll blocks of a finishing mill includes a fixture trolley and a disassembly and assembly mechanism mounted on the fixture trolley. The disassembly and assembly mechanism includes a guide rail and an adjusting wedge. The adjusting wedge includes a slider base and an upper sliding wedge. The slider base slides within the guide rail, and its upper surface is a first inclined surface. The upper sliding wedge is mounted on the slider base, and its lower surface is a second inclined surface adapted to the upper surface of the slider base. The upper sliding wedge is also connected to the slider base via an adjusting stud. Rotation of the adjusting stud can drive the upper sliding wedge to move linearly along the first inclined surface, thereby adjusting the height of the upper sliding wedge. The fixture trolley moves to align the disassembly and assembly mechanism with the bent roll block. The upper sliding wedge connects to the disassembled bent roll block. The slider base moves along the guide rail toward a direction away from the finishing mill, thereby transporting the bent roll block onto the fixture trolley.

[0008] Preferably, the guide rails are provided with two rails and two sets of adjusting wedges. The two guide rails are arranged in parallel and spaced apart.

[0015] This utility model also provides a disassembly and assembly fixture for disassembling and assembling bent roll blocks of a finishing mill. It includes a fixture trolley, a first disassembly and assembly mechanism, and a second disassembly and assembly mechanism. The finishing mill has a first bent roll block and a second bent roll block spaced a first distance apart. The first disassembly and assembly mechanism and the second disassembly and assembly mechanism are spaced a first distance apart. Both the first disassembly and assembly mechanism and the second disassembly and assembly mechanism include a guide rail and an adjusting wedge. The adjusting wedge includes a slider base and an upper sliding wedge. The slider base is slidably disposed within the guide rail, and the upper surface of the slider base is a first inclined surface. The upper sliding wedge is mounted on the slider base. The lower surface of the upper sliding wedge is a second inclined surface adapted to the upper surface of the slider base. The upper sliding wedge is also connected to the slider base via an adjusting stud.

The adjusting wedge includes a slider base and an upper sliding wedge. The slider base slides within the guide rail, and its upper surface is a first inclined surface. The upper sliding wedge is mounted on the slider base, and its lower surface is a second inclined surface adapted to the upper surface of the slider base.

[0030] Example 1

[0031] like Figure 1-5As shown, this embodiment discloses a disassembly and assembly fixture for disassembling and assembling the bending roll block 200 of a finishing mill. The disassembly and assembly fixture includes a fixture trolley 100 and a disassembly and assembly mechanism disposed on the fixture trolley 100. The disassembly and assembly mechanism includes a guide rail and an adjusting wedge 400. The adjusting wedge 400 includes a slider base 410 and an upper sliding wedge 420. The slider base 410 is slidably disposed within the guide rail 300, and the upper surface of the slider base 410 is a first inclined surface. The upper sliding wedge 420 is mounted on the slider base 410, and the lower surface of the upper sliding wedge 420 is a second inclined surface adapted to the upper surface of the slider base 410, that is, the lower surface of the upper sliding wedge 420 and the upper surface of the slider base 410 have the same inclination angle. The upper sliding wedge 420 is also connected to the slider base 410 via an adjusting stud 430. The rotation of the adjusting stud 430 can drive the upper sliding wedge 420 to move linearly along the first inclined plane, thereby adjusting the height of the upper sliding wedge 420. The tooling trolley 100 moves so that the disassembly and assembly mechanism is aligned with the bending roll block 200. The upper sliding wedge 420 is connected to the disassembled bending roll block 200. The slider base 410 moves along the guide rail 300 in a direction away from the finishing mill, thereby transporting the bending roll block 200 onto the tooling trolley 100.

[0032] Specifically, such as Figure 4 As shown, the slider base 410 has an L-shaped structure, including a horizontally arranged first horizontal portion and a vertically arranged first vertical portion. The upper sliding wedge 420 also has an L-shaped structure, including a horizontally arranged second horizontal portion and a vertically arranged second vertical portion. In this embodiment, the guide rail 300 is arranged along the width direction of the tooling carriage 100, and the first horizontal portion of the slider base 410 slides within the guide rail 300, that is, the first horizontal portion of the slider base 410 is arranged along the width direction of the tooling carriage 100, and the upper surface of the first horizontal portion is the first inclined surface, and its inclination direction is upward from the side near the bending roller block 200 toward the side away from the bending roller block 200 (the thickness of the side near the bending roller block 200 is less than the thickness of the side away from the bending roller block 200). The second horizontal portion of the upper sliding wedge 420 overlaps the first horizontal portion, and the lower surface of the second horizontal portion is the second inclined surface. The inclination direction of the second inclined surface is upward from the side closer to the bending roller block 200 toward the side farther from the bending roller block 200 (the thickness of the side closer to the bending roller block 200 is greater than the thickness of the side farther from the bending roller block 200). Furthermore, the inclination angle of the second inclined surface and the first inclined surface are the same, so that the second inclined surface is adapted to the first inclined surface.

[0033] Furthermore, the first vertical portion of the slider base 410 has a through hole (without threads), and the second vertical portion has a threaded hole. The adjusting stud 430 is a double-ended stud. One end of the double-ended stud passes through the through hole on the first vertical portion and is fixed by a nut, while the other end is threadedly connected to the threaded hole on the second vertical portion. By simply turning the nut to rotate the adjusting stud 430, the upper sliding wedge 420 can move linearly along the length of the first horizontal portion of the slider base 410, thereby fine-tuning the height of the upper sliding wedge 420 to ensure that the upper sliding wedge 420 can be precisely aligned with the bottom of the curved roller block 200.

[0034] like Figure 4 As shown, in this embodiment, the upper surface of the upper sliding wedge 420 is a horizontal plane. When the upper sliding wedge 420 is connected to the bending roller block 200, the bending roller block 200 overlaps on the upper surface of the upper sliding wedge 420, and the upper surface of the upper sliding wedge 420 supports the bending roller block 200.

[0035] like Figure 1 , 2 As shown, specifically, there are two guide rails 300 and two sets of adjusting wedges 400. The two guide rails 300 are arranged in parallel and spaced apart, and the distance between the two guide rails 300 is the same as the width of the bending roller block 200. The two sets of adjusting wedges 400 are respectively arranged in the two guide rails 300, and the two sets of adjusting wedges 400 are respectively used to align and connect with the two sides of the bending roller block 200 in the width direction.

[0036] like Figure 3 , 5 As shown, the disassembly and assembly mechanism further includes a connecting plate 500, which is located between the adjusting wedge 400 and the bending roller block 200. The connecting plate 500 has a first bolt hole 510 and a second bolt hole 520. The second vertical part of the upper sliding wedge 420 also has a third bolt hole 421, and the bending roller block 200 also has bolt holes for connection with the connecting plate 500. First, the third bolt hole 421 of the upper sliding wedge 420 is aligned with the second bolt hole 520 of the connecting plate 500, and then the upper sliding wedge 420 and the connecting plate 500 are fixed together with bolts. Then, the height of the upper sliding wedge 420 and the connecting plate is finely adjusted by rotating the adjusting stud 430, so that the first bolt hole 510 of the connecting plate 500 is aligned with the bolt hole on the bending roller block 200. Then, the connecting plate 500 and the bending roller block 200 are connected as a whole with bolts, so that the upper surface of the upper sliding wedge 420 contacts the bottom of the bending roller block 200.

[0037] Specifically, the disassembly and assembly mechanism also includes a tensioning assembly. A first pull ring 530 is located at the center of the side of the connecting plate 500 away from the bending roll block 200, and a second pull ring 540 is located on the tooling trolley 100. The second pull ring 540 is located between two guide rails and is equidistant from both rails, meaning it is positioned precisely in the middle of the two guide rails. After the bending roll block 200 is fixedly connected to the connecting plate 500, all mounting screws on the bending roll block 200 can be removed, allowing it to separate from the mill stand 920. The two ends of the tensioning assembly are connected to the first pull ring 530 and the second pull ring 540, respectively, to pull the bending roll block 200 to the middle position in the width direction on the tooling trolley 100. The tensioning assembly uses a manual hoist.

[0038] like Figure 3 As shown, the side of the guide rail 300 is provided with a plurality of first through holes 310 at intervals, and the slider base 410 is provided with a second through hole 411. When the bending roller block 200 moves along the guide rail 300 to the middle position in the width direction on the tooling trolley 100, the second through hole 411 is aligned with one of the first through holes 310, and then the cotter pin 600 is inserted into the first through hole 310 and the second through hole 411 to fix the slider base 410.

[0039] The working process of the disassembly and assembly tooling in this embodiment is as follows:

[0040] When disassembling the curved roller block 200, the tooling trolley 100 first moves along the track 930 (its own length direction), from... Figure 1 Position moved to Figure 2 The position is such that the two guide rails 300 are aligned with the two sides of the bending roller block 200 in the width direction;

[0041] Then, align the third bolt hole 421 of the upper sliding wedge 420 with the second bolt hole 520 of the connecting plate 500, and then fix the upper sliding wedge 420 and the connecting plate 500 together with bolts.

[0042] Then, by rotating the adjusting stud 430, the height of the upper sliding wedge 420 and the connecting plate 500 is finely adjusted so that the first bolt hole 510 of the connecting plate 500 is aligned with the bolt hole on the bending roller block 200. Then, the connecting plate 500 and the bending roller block 200 are connected as one unit by bolts, so that the upper surface of the upper sliding wedge 420 contacts the bottom of the bending roller block 200.

[0043] Remove all mounting screws from the bent roll block 200 to separate it from the mill stand 920;

[0044] The two ends of the tension assembly are connected to the first pull ring 530 and the second pull ring 540 respectively. The tension assembly is activated to pull the bending roller block 200 to the middle position in the width direction on the tooling trolley 100.

[0045] Finally, the tooling trolley 100 moves in the opposite direction along track 930 (its own length direction), from... Figure 2 Position moved to Figure 1 The position is determined so that the bent roller block 200 is transported to the maintenance area.

[0046] It is worth noting that when installing the bending roller block 200, simply reverse the above steps.

[0047] In this embodiment, the disassembly and assembly fixture aligns the fixture trolley 100, equipped with a disassembly and assembly mechanism, with the bending roll block 200 of the finishing mill. The bending roll block 200 is then transported onto the fixture trolley 100 and then to the maintenance area. This avoids the use of a high-risk hoisting method for the bending roll block 200, thus improving the safety of disassembly and assembly, saving time, and increasing maintenance efficiency. The slider base 410 and the upper sliding wedge 420 are connected by a first inclined plane and a second inclined plane. The height of the upper sliding wedge 420 can be finely adjusted by adjusting the stud 430, ensuring precise alignment of the connecting plate 500 with the bending roll block 200 and improving the accuracy of disassembly and assembly. Both the slider base 410 and the fixture trolley 100 use a rail-type transportation method, effectively ensuring the stability and safety of the bending roll block 200 during transportation.

[0048] Example 2

[0049] like Figure 6-7 As shown, this embodiment discloses another disassembly and assembly fixture for disassembling and assembling the bent roll blocks of a finishing mill, including a fixture trolley 100, a first disassembly and assembly mechanism 700, and a second disassembly and assembly mechanism 800. The first disassembly and assembly mechanism 700 and the second disassembly and assembly mechanism 800 are exactly the same as the disassembly and assembly mechanism in Embodiment 1.

[0050] Specifically, the finishing mill has a first bent roll block 900 and a second bent roll block 910 spaced apart by a first distance, and both the first bent roll block 900 and the second bent roll block 910 are mounted on the mill stand 920. Furthermore, the first disassembly / assembly mechanism 700 and the second disassembly / assembly mechanism 800 are also spaced apart by the first distance.

[0051] Both the first disassembly / assembly mechanism 700 and the second disassembly / assembly mechanism 800 include a guide rail 300 and an adjusting wedge 400. The adjusting wedge 400 includes a slider base 410 and an upper sliding wedge 420. The slider base 410 is slidably disposed within the guide rail 300, and its upper surface is a first inclined surface. The upper sliding wedge 420 is mounted on the slider base 410, and its lower surface is a second inclined surface that matches the upper surface of the slider base 410. The upper sliding wedge 420 is also connected to the slider base 410 via an adjusting stud 430. The adjusting stud 430 rotates... The upper sliding wedge 420 can be driven to move linearly along the first inclined plane, thereby adjusting the height of the upper sliding wedge 420. The tooling trolley 100 moves so that the first disassembly and assembly mechanism 700 is aligned with the first bending roll block 900, the second disassembly and assembly mechanism 800 is aligned with the second bending roll block 910, the upper sliding wedge 420 is connected to the disassembled first bending roll block 900 and second bending roll block 910, and the slider base 410 moves along the guide rail 300 toward the direction away from the finishing mill, thereby transporting the first bending roll block 900 and the second bending roll block 910 onto the tooling trolley 100.

[0052] The working process of the disassembly and assembly tooling in this embodiment is as follows:

[0053] When disassembling the curved roller block, the tooling trolley 100 first moves along the track 930 (its own length direction), from... Figure 6 Position moved to Figure 7 The positions are such that the first disassembly and assembly mechanism 700 is aligned with the first bending roller block 900, and the second disassembly and assembly mechanism 800 is aligned with the second bending roller block 910.

[0054] Then, the first bending roller block 900 and the second bending roller block 910 are transported to the tooling trolley 100 respectively using the same steps as in Example 1;

[0055] Finally, the tooling trolley 100 moves in the opposite direction along track 930 (its own length direction), from... Figure 7 Position moved to Figure 6 The position is determined so that the first curved roller block 900 and the second curved roller block 910 are transported to the maintenance area.

[0056] It is worth noting that when installing the first bending roller block 900 and the second bending roller block 910, the above steps can be reversed.

[0057] Of course, if there are three or more bent roll blocks on the mill stand 920, it is only necessary to set the same number of disassembly and assembly mechanisms on the tooling trolley 100, and ensure that each disassembly and assembly mechanism can be aligned with each bent roll block respectively.

[0058] In this embodiment, the disassembly and assembly fixture aligns the fixture trolley 100, equipped with a disassembly and assembly mechanism, with the bending roll block of the finishing mill, and transports the bending roll block onto the fixture trolley 100. The fixture trolley 100 then transports the block to the maintenance area, thus avoiding the use of a high-risk hoisting method for the bending roll block, thereby improving the safety of disassembly and assembly, saving time, and increasing maintenance efficiency. Specifically, the slider base 410 and the upper sliding wedge 420 are connected by a first inclined plane and a second inclined plane. The height of the upper sliding wedge 420 can be finely adjusted by adjusting the stud 430, ensuring that the connecting plate 500 can be precisely aligned with the bending roll block, improving the accuracy of the bending roll block disassembly and assembly. Both the slider base 410 and the fixture trolley 100 adopt a rail-type transportation method, which effectively ensures the stability and safety of the bending roll block transportation.

[0059] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.

10. A disassembly and assembly tooling for disassembling and assembling bent roll blocks of a finishing mill, characterized in that, The mill includes a tooling trolley (100), a first disassembly / assembly mechanism (700), and a second disassembly / assembly mechanism (800). The finishing mill has a first bending roll block (900) and a second bending roll block (920) spaced apart by a first distance. The first disassembly / assembly mechanism (700) and the second disassembly / assembly mechanism (800) are spaced apart by a first distance. Both the first disassembly / assembly mechanism (700) and the second disassembly / assembly mechanism (800) include a guide rail (300) and an adjusting wedge (400). The adjusting wedge (400) includes a slider base (410) and an upper sliding wedge (420). The slider base (410) is slidably disposed within the guide rail (300), and the upper surface of the slider base (410) is a first inclined surface. The upper sliding wedge (420) is mounted on the slider base (410), and the lower surface of the upper sliding wedge (420) is perpendicular to the slider base. The upper surface of (410) is adapted to the second inclined surface. The upper sliding wedge (420) is also connected to the slider base (410) through the adjusting stud (430). The rotation of the adjusting stud (430) can drive the upper sliding wedge (420) to move linearly along the first inclined surface, thereby adjusting the height of the upper sliding wedge (420). The tooling trolley (100) moves so that the first disassembly mechanism (700) is aligned with the first bending roll block (900), and the second disassembly mechanism (800) is aligned with the second bending roll block (920). The upper sliding wedge (420) is connected to the disassembled first bending roll block (900) and second bending roll block (920). The slider base (410) moves along the guide rail (300) toward the direction away from the finishing mill, thereby transporting the first bending roll block (900) and the second bending roll block (920) onto the tooling trolley (100).
