Description

Technical Field

[0001] This utility model belongs to the field of steel coil processing technology, specifically an integrated equipment for uncoiling and straightening hot-rolled small steel coils. Background Technology

[0002] Hot-rolled steel coils are produced for easy storage and transportation, or for various processing (such as processing into steel plates, strips, etc.). They are made by heating steel billets to a high temperature, rolling them to the required thickness and width, and then hot-pressing the steel into coils. Uncoils are specialized equipment for leveling metal sheets. They are mainly used to unwind coiled materials such as steel coils and guide the material head into the subsequent processing line. The uncoiler drum typically applies a certain pressure to the steel coil to generate sufficient friction so that the drum can rotate the coil without slipping, and to prevent the coil from uncoiling or undergoing irregular deformation, which could affect subsequent straightening. However, applying too much pressure can easily deform or damage the sheet metal, while applying too little pressure will result in insufficient friction, making it difficult for the drum to rotate the coil, causing it to slip and the coil to unravel. Hot-rolled steel coils are subject to temperature variations, and the physical properties of the sheet metal differ at different temperatures, requiring different pressures. The lower the temperature, the greater the hardness and deformation resistance of the sheet metal, and the greater the pressure that the drum needs to apply to the coil. Existing uncoilers lack dynamic pressure leveling designs for hot-rolled coils, resulting in a high scrap rate. Utility Model Content

[0003] The purpose of this utility model is to provide an integrated uncoiling and straightening device for hot-rolled small steel coils, so as to solve at least one aspect of the problems and defects mentioned in the background art.

Several upper straightening rollers are arranged on the side of the upper support base near the lower support base, and several lower straightening rollers are arranged on the side of the lower support base near the upper support base. The upper and lower straightening rollers are arranged in an alternating pattern.

[0010] Furthermore, the clamping arm adjustment module includes a support base, a clamping roller, a movable plate, and a support plate. The support plate is fixedly installed on the support base, and the movable plate is rotatably installed on the support base. A fifth hydraulic press is installed on the fixed plate, and the fifth hydraulic press is connected to a fifth hydraulic rod. One end of the clamping roller is rotatably installed on the movable plate, and the other end is rotatably installed on the telescopic end of the fifth hydraulic rod.

[0011] Furthermore, an oxide scale treatment module is provided between the roller straightening module and the uncoiling and anti-loosening module. The oxide scale treatment module includes a first support and a cleaning roller. The cleaning roller is equipped with a rubber roller brush on its roller surface. The cleaning roller is rotatably mounted on the first support via a rotating shaft. A rotary motor is connected to the end of the cleaning roller's rotating shaft.

[0013] Furthermore, it also includes a base frame with an open top and a top plate. The base frame is equipped with a shock absorber inside, which abuts against the top plate. The leveling mechanism and the roller straightening module are both located on the top of the top plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This solution dynamically adjusts the pressure applied to the steel coil by cooperating with a temperature sensor, an expansion mechanism, and an external control device. The temperature sensor senses the temperature of the steel coil in real time and transmits the signal to the control device. The control device controls the expansion mechanism to contract and expand in real time according to the set temperature value. The lower the temperature, the greater the expansion mechanism expands, and the greater the pressure applied to the steel coil. This reduces the probability of insufficient friction leading to uncoiling failure or loosening of the steel coil due to the increased deformation resistance and hardness caused by the lower temperature.

[0016] 2. Apply pressure from the outside of the steel coil through the clamping arm adjustment module to further reduce the probability of the steel coil loosening. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-9As shown in the embodiment of this utility model, an integrated uncoiling and straightening device for hot-rolled small steel coils includes an uncoiling anti-loosening module 9 and a leveling mechanism. A roller straightening module 5 is provided between the uncoiling anti-loosening module 9 and the leveling mechanism. A clamping arm adjustment module 10 is provided next to the uncoiling anti-loosening module 9. The uncoiling anti-loosening module 9 includes a drum 91 and a temperature sensor 93. The temperature sensor 93 is installed on the drum 91. Several diameter-expanding mechanisms are arranged along the circumference of the outer wall of the drum 91. The diameter-expanding mechanism includes a diameter-expanding arc plate 92 and a telescopic rod 94. The telescopic rod 94 is driven by a motor (not shown). One end of the telescopic rod 94 is installed on the outer wall of the drum 91, and the other end is connected to the diameter-expanding arc plate 92. The temperature sensor 93 and the diameter-expanding mechanism are connected to an external control device (existing technology, not shown). In use, the steel coil 8 is fitted onto the expansion arc plate 92, so that the expansion arc plate 92 abuts against the inner ring of the steel coil 8. The temperature sensor 93 transmits the current temperature value to the control device in real time. The control device controls the extension and retraction of the telescopic rod 94 according to the temperature set value. The lower the temperature, the greater the hardness and deformation resistance of the steel coil 8. The control device manipulates the telescopic rod 94 to apply a greater extension force, so as to apply sufficient pressure through the expansion arc plate 92, thereby reducing the probability of the steel coil 8 slipping or loosening without damaging it.

[0031] In one embodiment, see Figure 2 As shown, the leveling mechanism includes a support frame 101, in which an upper working roller 2 and a lower working roller 21 are symmetrically arranged vertically. A spacing adjustment mechanism is provided between the upper working roller 2 and the lower working roller 21. A pressure mechanism is provided above the upper working roller 2 and below the lower working roller 21.

[0032] Specifically, the spacing adjustment mechanism includes a hydraulic telescopic mechanism and two symmetrically arranged mounting plates 107. The hydraulic telescopic mechanism includes two second hydraulic rods 106, both of which are mounted on the inner wall of the support frame 101. The telescopic end of one second hydraulic rod 106 is connected to the upper mounting plate 107, and the telescopic end of the other second hydraulic rod 106 is connected to the lower mounting plate 107. The second hydraulic rods 106 are connected to the second hydraulic press 105. The hydraulic telescopic mechanism includes two sets, which are respectively mounted on both ends of the two mounting plates 107. The upper working roller 2 is rotatably mounted on the upper mounting plate 107 (bearings are mounted on the mounting plate 107). The shaft at the end of the upper working roll 2 passes through the inner ring of the bearing (this is a common installation method for rolls, not shown). The lower working roll 21 is rotatably mounted on the mounting plate 107 below (the same installation method as the upper working roll 2). The upper working roll 2 and the lower working roll 21 are driven to rotate by a motor (a common structure, not shown). The extension and retraction of the second hydraulic rod 106 can be controlled by the second hydraulic press 105. By extending and retracting different parts of the second hydraulic rod 106, the two mounting plates 107 can be moved up and down to adjust the distance between the upper working roll 2 and the lower working roll 21. The distance between the upper working roll 2 and the lower working roll 21 can be freely adjusted according to the thickness of the steel plate after uncoiling.

[0033] The pressure mechanism includes a first hydraulic press 102, a first hydraulic rod 103, and a fixed frame 104. The first hydraulic press 102 is installed inside the support frame 101. One end of the first hydraulic rod 103 is connected to the first hydraulic press 102, and the other end is connected to the fixed frame 104. A leveling support roller 1 (a common installation method for rollers, the same as the installation method for working rollers) is rotatably installed on the fixed frame 104. The upper leveling support roller 1 abuts against the upper working roller 2, and the lower leveling support roller 1 abuts against the lower working roller 21. The first hydraulic press 102 drives the first hydraulic rod 103 to extend and retract, thereby controlling the pressure applied by the leveling support roller 1 to the upper working roller 2 and the lower working roller 21, and thus controlling the pressure applied to the uncoiled steel plate passing between the upper working roller 2 and the lower working roller 21. The magnitude of the applied pressure can be adjusted according to the temperature and thickness of the uncoiled steel plate, so as to level the steel plate without damaging it.

[0034] In one embodiment, see Figure 3 As shown, the roller straightening module 5 includes a straightening machine frame 51, an upper support base 52, and a lower support base 53. A third hydraulic press 58 is mounted on the straightening machine frame 51, and a third hydraulic rod 54 is connected to the third hydraulic press 58. Multiple sets of the third hydraulic press 58 and the third hydraulic rod 54 can be set as needed. The third hydraulic rod 54 is connected to the upper support base 52. Several upper straightening rollers 55 are arranged on the side of the upper support base 52 near the lower support base 53, and several lower straightening rollers 551 are arranged on the side of the lower support base 53 near the upper support base 52. (The upper straightening rollers 55 and lower straightening rollers 551 are installed in the same way as the working rollers and can be rotated.) The lower support 53 is fixed below the upper support 52 by a fixing rod 56. The upper straightening roller 55 and the lower straightening roller 551 are arranged alternately. Both the upper straightening roller 55 and the lower straightening roller 551 are driven to rotate by a motor (common technology, not shown). The third hydraulic press 58 provides driving force to drive the third hydraulic rod 54 to extend and retract, so as to adjust the distance between the upper straightening roller 55 and the lower straightening roller 551, so as to adjust the pressure on the uncoiled steel plate passing between the upper straightening roller 55 and the lower straightening roller 551. The pressure can be adjusted according to the temperature and thickness of the steel plate, so as to straighten the steel plate without damaging it.

[0035] It should be noted that if the upper support 52 tilts due to installation reasons, balance blocks 57 can be added to both sides of the upper support 52. Balance blocks 57 with different weights can be used according to the degree of tilt to ensure that the upper support 52 is not tilted.

[0036] In one embodiment, see Figure 8As shown, the clamping arm adjustment module 10 includes a support base 1001, a movable plate 1002, a support plate 1003, and a clamping roller 1006. The support plate 1003 is fixedly installed on the support base 1001, and the movable plate 1002 is rotatably installed on the support base 1001 (a rotating movable roller 1007 is fixedly installed at the end of the movable plate 1002, a column is provided on the support base 1001, a bearing is installed on the column, and the shaft at the end of the rotating movable roller 1007 passes through the bearing; the column and bearing are not shown). A fifth hydraulic press 1004 is installed on 1003. The fifth hydraulic press 1004 is connected to a fifth hydraulic rod 1005. One end of the pressure roller 1006 is rotatably installed on the movable plate 1002 (a common installation method for rollers, with a bearing installed on the movable plate 1002, and the shaft of one end of the pressure roller 1006 passing through the bearing), and the other end is rotatably installed on the telescopic end of the fifth hydraulic rod 1005 (a common installation method for rollers, with a bearing installed on the telescopic end of the fifth hydraulic rod 1005, and the shaft of one end of the pressure roller 1006 passing through the bearing). In use, the clamping arm adjustment module 10 is placed next to the uncoiling anti-loosening module 9 so that the clamping roller 1006 abuts against the steel coil 8. The clamping roller 1006 presses down on the outer ring of the steel coil 8, reducing the probability of the steel coil 8 loosening when uncoiling. When the steel coil 8 becomes smaller as the uncoiling diameter decreases, the fifth hydraulic rod 1005 can be extended by operating it to make the movable plate 1002 flip towards the steel coil 8, so that the clamping roller 1006 can always abut against the steel coil 8.

[0037] In one embodiment, see Figure 4 As shown, an oxide scale treatment module 6 is provided between the roller straightening module 5 and the uncoiling and anti-loosening module 9. The oxide scale treatment module 6 includes a first support 61 and a cleaning roller 63. A rubber roller brush 64 is provided on the roller surface of the cleaning roller 63. The cleaning roller 63 is rotatably mounted on the first support 61 (a common installation method for rollers, with a bearing installed on the first support 61, and the rotating shaft 62 at the end of the cleaning roller 63 passing through the bearing). The rotating shaft 62 of the cleaning roller 63 (a common structure, a shaft fixedly installed on both sides of the roller) is connected to a rotary motor 65. For easy installation, the rotary motor 65 can be installed on the ground. Gears are installed on both the output shaft of the rotary motor 65 and the rotating shaft 62. Through the meshing of the gears, the power provided by the rotary motor 65 is transmitted to the rotating shaft 62 (a common structure of rotary motor transmission, the gears are not shown). In use, the surface of the cleaning roller 63 is brought into contact with the uncoiled steel plate, and the cleaning roller 63 starts to rotate under the drive of the rotary motor 65. The oxide scale on the steel plate can be removed by rotating the rubber roller brush 64 on the surface of the cleaning roller 63.

[0038] In one embodiment, see Figure 5 , Figure 6As shown, an inlet clamping mechanism is provided between the roller straightening module 5 and the uncoiling and anti-loosening module 9. The inlet clamping mechanism includes a second support 111 and a fixed frame 71. An inlet support roller 11 (a common installation method for rollers) is rotatably mounted on the second support 111. A bearing is installed on the second support 111, and the shaft at the end of the inlet support roller 11 passes through the bearing. An L-shaped rotating plate 76 and a fourth hydraulic press 72 are provided on the fixed frame 71. One end of the L-shaped rotating plate 76 is rotatably mounted on one end of the fixed frame 71 (by rotating...). The movable rod 75 passes through the end of the L-shaped rotating plate 76 and the end of the fixed frame 71, so that the L-shaped rotating plate 76 can be flipped on the fixed frame 71. The other end of the L-shaped rotating plate 76 is rotatably equipped with an inlet pinch roller 7 (a common installation method for rollers, with a bearing installed at the end of the L-shaped rotating plate 76, and the shaft at the end of the inlet pinch roller 7 passing through the bearing). The fourth hydraulic press 72 is connected to the fourth hydraulic rod 73, and the telescopic end of the fourth hydraulic rod 73 is movably connected to the L-shaped rotating plate 76. The inlet support roller 11 is located below the inlet pinch roller 7.

[0039] Specifically, bearings (not shown) are installed on both the telescopic end of the fourth hydraulic rod 73 and the L-shaped rotating plate 76. A positioning rod 74 passes through the bearings on both the telescopic end of the fourth hydraulic rod 73 and the L-shaped rotating plate 76. This design allows the telescopic movement of the fourth hydraulic rod 73 to drive the L-shaped rotating plate 76 to rotate. In use, the inlet pinch roller 7 should abut against the top surface of the uncoiled steel plate, and the inlet support roller 11 should abut against the bottom surface of the uncoiled steel plate. It is important to note that the horizontal height of the inlet pinch mechanism should be equivalent to that of the roller straightening module 5 to ensure that the uncoiled steel plate can smoothly enter the roller straightening module 5 without any tilt angle.

[0040] In one embodiment, see Figure 9 As shown, it also includes a base frame 401, with an open top. A top plate 4 is located on the top of the base frame 401, and a shock absorber 3 (existing technology) is installed inside the base frame 401, abutting against the top plate 4. The leveling mechanism and the roller straightening module 5 are both located on top of the top plate 4. This design effectively reduces the vibration of the leveling mechanism and the roller straightening module 5, making operation smoother. It should be noted that the oxide scale treatment module 6 and the inlet clamping mechanism can also be installed on top of the top plate 4, using the shock absorber 3 to reduce vibrations generated during operation.

[0041] In this solution, all hydraulic presses and all roller drive motors can be uniformly controlled through an external control device.

[0042] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
