Description

Technical Field

[0001] This utility model relates to the field of uncoiling and straightening technology, and in particular to an uncoiling and straightening detection device for hot-rolled steel strip. Background Technology

[0002] Hot-rolled steel strip refers to steel strip products made from steel billets through multiple rolling passes on a hot rolling mill after being heated to high temperatures. Due to the high-temperature rolling process, hot-rolled steel strip possesses excellent plasticity and processability, making it suitable for further processing such as cold rolling, pickling, galvanizing, and coating. Hot-rolled steel strip is widely used in construction, machinery manufacturing, automotive industry, shipbuilding, pipelines, and home appliances, meeting the strength, toughness, and flatness requirements of structural components, appearance parts, and functional parts. Its surface is typically dark in color and has an oxide scale, but different surface quality standards can be achieved through subsequent treatments.

[0003] During the uncoiling process of hot-rolled steel strip, specialized straightening equipment is required to straighten and inspect defects such as curling, transverse ripples, edge warping, and localized thickness unevenness. Currently, most existing straightening and inspection devices employ two sets of combined flattening rollers to level the uncoiled steel strip. While this two-set design is simple and easy to operate, it has shortcomings in practical applications: firstly, it is difficult to effectively straighten defects such as curling, transverse ripples, edge warping, and localized thickness unevenness; secondly, it cannot flexibly adjust the spacing of the flattening rollers according to the steel strip thickness specifications, and it cannot provide effective correction and limiting functions during the leveling process. Therefore, existing devices have certain limitations in use and cannot meet the requirements of high-quality steel strip production for leveling effect and processing accuracy.

[0004] Based on this, we propose an uncoiling and straightening detection device for hot-rolled steel strip to solve the problems mentioned above. Utility Model Content

[0018] 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.

[0019] Example: Refer to Figures 1 to 6This utility model provides an embodiment of a hot-rolled steel strip uncoiling and straightening detection device, including a support base 1. A coil flattening assembly 2 is installed on the top of the support base 1. A straightening detection assembly 3 is connected to one side of the coil flattening assembly 2. A steel strip coil body 4 is also conveyed between the straightening detection assembly 3 and the coil flattening assembly 2. The straightening detection assembly 3 includes a mounting frame 5. A discharge port 6 is opened through the middle of the mounting frame 5. Detection sensors 7 are provided on both sides of the inner wall of the discharge port 6. Guide rods 8 are slidably connected to both ends of the mounting frame 5. Positioning blocks 9 are installed at one end of each of the two sets of guide rods 8. The two sets of positioning blocks 9 are located at both ends of the inner wall of the discharge port 6. Compression springs 10 are also sleeved on the outer side of the two sets of guide rods 8 near the positioning blocks 9. The flattening component 2 includes a mounting frame 11. Inside the mounting frame 11, four sets of first flattening rollers 12 are connected via bearings. Two sets of first flattening rollers 12 have a first transmission gear 13 installed at one end. Four sets of support rods 14 are connected to the side of the mounting frame 11 near the first flattening rollers 12. A flattening adjustment component 15 is provided between the two sets of support rods 14. A transmission gear 16 is installed at one end of each of the four sets of first flattening rollers 12. A transmission chain 17 is also meshed between the two sets of transmission gear 16. By adding the transmission gear 16 and transmission chain 17 to one end of each of the four sets of first flattening rollers 12, the synchronous operation of the four sets of first flattening rollers 12 can be ensured, avoiding local stretching or wrinkling, and achieving high-precision processing of the steel strip coil in the initial flattening stage.

[0020] Several sets of adjustment slots 18 are respectively opened on both sides of the mounting frame 11. Guide rails 19 are also installed on both sides of the inner wall of the adjustment slots 18. Through the several sets of adjustment slots 18 opened on both sides of the mounting frame 11 and the guide rails 19 provided on both sides of their inner walls, a precise sliding guide channel can be provided for the adjustment base block 21 in the flattening adjustment component 15. This can effectively prevent the adjustment base block 21 from tilting or shifting during operation, and can ensure that the distance between the second flattening roller 20 and the first flattening roller 12 can be accurately adjusted. This enables precise straightening processing of steel strip coil bodies 4 with different thicknesses and improves the operational stability and processing accuracy of the flattening device. The flattening adjustment component 15 includes a second flattening roller 20. The two ends of the second flattening roller 20 are connected to the adjustment base block 21 through bearings. The adjustment base block 21 is structurally matched with the adjustment slot 18. The adjusting base block 21 has guide grooves 22 on both sides. The guide grooves 22 and the guide rails 19 are in sliding fit. Through the structural design of the sliding fit between the guide grooves 22 and the guide rails 19, the second pressing roller 20 can move smoothly along the predetermined trajectory and the distance between it and the first pressing roller 12 can be precisely adjusted. This facilitates high-precision straightening of steel strips of different specifications. The top of the two sets of adjusting base blocks 21 is connected to the adjusting screw 23 through the bearing. The middle of the adjusting screw 23 is also threadedly connected to the fixing plate 24. Through the structural design of the threaded fit between the adjusting screw 23 and the fixing plate 24, the adjusting base block 21 can be rotated to drive the two sets of adjusting base blocks 21 to uniformly adjust the distance between the second pressing roller 20 and the first pressing roller 12, so as to achieve precise adaptation to the thickness difference of the steel strip coil body 4.

[0021] A detection control box 25 is installed on the top of the support base 1, and a drive motor 26 is installed on the bottom of the support base 1. The output end of the drive motor 26 is connected to a transmission connector 27. A reducer 28 is set on the top side of the support base 1 near the detection control box 25. The reducer 28 is connected to the transmission connector 27 via a transmission belt. A second transmission gear 29 is also installed on the output end of the reducer 28. The second transmission gear 29 is meshed with two sets of first transmission gears 13. Through the cooperation of the detection control box 25, drive motor 26, transmission connector 27, reducer 28, and second transmission gear 29, and the structural design of the meshing connection between the second transmission gear 29 and the two sets of first transmission gears 13, the support base 1 provides stable power through the drive motor 26. The output speed is adjusted by the reducer 28 and evenly distributed to the four sets of first flattening rollers 12 through the transmission gear system. This ensures that the four sets of first flattening rollers 12 operate synchronously and achieve uniform flattening of the steel strip coil body 4.

[0022] Working Principle: The coil straightening and detection device designed in this scheme, through the coordinated use of components such as the mounting frame 11, the first flattening roller 12, the first transmission gear 13, the support rod 14, the flattening adjustment component 15, the transmission gear 16, and the transmission chain 17, can flexibly adjust the distance between the second flattening roller 20 and the first flattening roller 12 to meet the straightening processing requirements of steel strip coil bodies 4 with different thicknesses. Specifically, when the steel strip coil body 4 enters the coil flattening assembly 2, the mounting frame 11 serves as the basic support, the first... A flattening roller 12 is connected by a bearing and driven to rotate by a first transmission gear 13, which can perform preliminary flattening on the steel strip coil body 4. At the same time, the second flattening roller 20 in the flattening adjustment component 15 can be adjusted according to the thickness specification of the steel strip. By cooperating with the adjusting screw 23 and the fixed frame plate 24, the adjusting base block 21 is driven to slide along the adjusting groove 18, which can change the distance between the second flattening roller 20 and the first flattening roller 12. The transmission gear 16 and the transmission chain 17 ensure synchronous transmission between each flattening roller to achieve uniform flattening.

[0023] The coil straightening and detection device designed in this scheme, through the coordinated use of components such as the mounting frame 5, the discharge port 6, the detection sensor 7, the guide rod 8, the positioning block 9, and the compression spring 10, can play a role in preventing deviation and clamping on both sides of the steel strip coil body 4 during the leveling process between the second flattening roller 20 and the first flattening roller 12. This prevents the steel strip coil body 4 from shifting during the leveling and conveying process and causing processing accidents. Specifically, when the steel strip coil body 4 enters the straightening and detection component 3 after being flattened, the discharge port 6 can guide the steel strip coil body 4 to pass smoothly. The detection sensor 7 can monitor the flatness and position of the steel strip coil body 4 in real time to ensure processing quality. The guide rod 8 and the positioning block 9 clamp and position the steel strip at both ends of the inner wall of the discharge port 6 to prevent it from shifting. The compression spring 10 is installed at the end of the guide rod 8 near the positioning block 9 and can use its elastic properties to apply an appropriate clamping force to the steel strip coil body 4 to ensure that the steel strip coil body 4 remains stable during the conveying process.
