Description
Technical Field
[0001] This utility model relates to the field of hot-rolled coil leveling technology, specifically a hot-rolled coil leveling and straightening device. Background Technology
[0002] Hot-rolled coils are thin sheet metal products made by pressing and deforming metal billets at high temperatures using a rolling mill. Due to their excellent mechanical properties, processing performance, and stability, they are widely used in various fields such as automobile manufacturing, aerospace, shipbuilding, construction, machinery, and pressure vessels. Hot-rolled coils are produced by cooling hot steel strip from the last stand of the finishing mill to a set temperature using laminar flow cooling, and then coiling them into steel strip coils by a coiler. After cooling, the steel strip coils are processed according to different user needs through various finishing lines (leveling, straightening, cross-cutting or longitudinal cutting, inspection, weighing, packaging, and marking, etc.) to become steel plates, leveled coils, and longitudinally cut steel strip products. Hot-rolled coils can also be cut into coils of different widths according to customer requirements.
[0003] In the application of hot-rolled coils, the hot-rolled coils need to be uncoiled and leveled by a leveling machine first, and then the leveled plates are conveyed to a shearing machine. The shearing machine then cuts the leveled plates into steel plates of the target length, and finally the cut steel plates are transported away by a conveying mechanism.
[0004] However, existing uncoiling and leveling equipment typically uses two clamping plates to compress and level the steel coils. This method cannot effectively flatten the coils in a short time, requiring a certain amount of time to achieve leveling, thus severely impacting the leveling efficiency. Therefore, there is an urgent need for a hot-rolled coil leveling and straightening device to solve this problem. Utility Model Content
[0005] The purpose of this invention is to provide a hot-rolled coil leveling and straightening device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot-rolled coil leveling and straightening device, comprising a platform, an adjusting box fixedly installed on the upper end face of the platform, arc-shaped grooves opened on the upper and lower sides of the front end face of the adjusting box, a sliding column slidably installed in the inner cavity of the arc-shaped groove, an adjusting mechanism provided in the inner cavity of the adjusting box, flattening rollers provided on the upper and lower sides of the front end face of the adjusting box, a top plate provided at the front end of the flattening rollers, a flattening mechanism provided on the front end face of the top plate, and a coating mechanism provided on the left side of the front end face of the top plate.
[0007] Preferably, the adjustment mechanism includes an adjustment motor fixedly mounted on the upper end face of the adjustment box via a frame, and a bidirectional threaded rod rotatably mounted in the middle of the inner cavity of the adjustment box. Sliding seats are threaded on the upper and lower sides of the side wall of the bidirectional threaded rod. The sliding column is rotatably connected to the sliding seats, and the sliding column is fixedly connected to the flattening roller.
[0008] Preferably, the output shaft end of the regulating motor passes through the regulating box and is fixedly connected to the bidirectional threaded rod. The upper and lower ends of the bidirectional threaded rod have opposite thread directions, and the sliding seat slides in the inner cavity of the regulating box.
[0009] Preferably, the flattening mechanism includes a flattening motor fixedly mounted on the side wall of the top plate via a frame, and a transmission rod rotatably mounted in the middle of the inner cavity of the top plate. The output shaft end of the flattening motor is fixedly connected to the transmission rod, and the transmission rod is fixedly connected to the flattening roller.
[0010] Preferably, a limiting groove is formed on the left side wall of the adjustment box, and an extension rod is slidably installed in the inner cavity of the limiting groove, and the extension rod is fixedly connected to the top plate.
[0011] Preferably, the coating mechanism includes a liquid pump fixedly installed on the left side of the front end face of the top plate, and a connecting ring rotatably installed on the side wall of the transmission rod. The transmission rod is hollow, and an opening is provided on the side wall of the transmission rod in the inner cavity of the connecting ring.
[0012] Preferably, the inner cavity of the flattening roller is hollow, the flattening roller is connected to the transmission rod, a coating nozzle is fixedly installed on the side wall of the flattening roller, and the side wall of the liquid pump is connected to the connecting ring through the liquid inlet pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this utility model, the user can start the adjustment motor to make the bidirectional threaded rod rotate. Since the upper and lower threads of the bidirectional threaded rod are in opposite directions, the sliding seat slides in the inner cavity of the adjustment box. At this time, under the limiting constraint of the arc groove on the sliding column, the upper and lower sliding seats will move away from or towards the side wall of the bidirectional threaded rod at the same time, so that the distance between the two flattening rollers changes. At this time, the gap between the two flattening rollers will change, so that the whole device can be used for hot-rolled coils of different thicknesses, improving the practicality of the whole device.
[0015] 2. In this utility model, the user can start the flattening motors on both the upper and lower sides, causing the transmission rod to drive the two flattening rollers to rotate in opposite directions. When the hot-rolled coil passes through the flattening rollers, the friction of the flattening rollers continuously conveys and flattens the hot-rolled coil. While the flattening rollers on both the upper and lower sides are rotating, the user can start the liquid pump to introduce rust-preventive liquid from the outside. The liquid enters the connecting ring through the liquid inlet pipe, then enters its inner cavity through the opening on the connecting rod, and finally enters the flattening roller and is sprayed out from the coating nozzle. Combined with the other smooth surfaces of the flattening roller, the hot-rolled coil can be flattened and rust-preventive treatment can be performed at the same time, reducing the production steps of the hot-rolled coil and thus greatly improving the production efficiency of the hot-rolled coil.

[0021] 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.
[0022] Please see Figures 1-4This utility model provides a technical solution for a hot-rolled coil leveling and straightening device: A hot-rolled coil leveling and straightening device includes a base 1, an adjusting box 2 fixedly installed on the upper end face of the base 1, an arc-shaped groove 21 opened on the upper and lower sides of the front end face of the adjusting box 2, a sliding column 22 slidably installed in the inner cavity of the arc-shaped groove 21, an adjusting mechanism 3 provided in the inner cavity of the adjusting box 2, a flattening roller 4 provided on the upper and lower sides of the front end face of the adjusting box 2, a top plate 5 provided at the front end of the flattening roller 4, a flattening mechanism 6 provided on the front end face of the top plate 5, and a coating mechanism 7 provided on the left side of the front end face of the top plate 5.
[0023] Furthermore, the adjustment mechanism 3 includes an adjustment motor 31 fixedly mounted on the upper end face of the adjustment box 2 via a frame, and a bidirectional threaded rod 32 rotatably mounted in the middle of the inner cavity of the adjustment box 2. Sliding seats 33 are threaded on the upper and lower sides of the side wall of the bidirectional threaded rod 32. The sliding column 22 is rotatably connected to the sliding seat 33, and the sliding column 22 is fixedly connected to the flattening roller 4.
[0024] The output shaft of the regulating motor 31 passes through the regulating box 2 and is fixedly connected to the bidirectional threaded rod 32. The upper and lower ends of the bidirectional threaded rod 32 have opposite thread directions, and the sliding seat 33 slides in the inner cavity of the regulating box 2.
[0025] It should be noted that the user can start the adjustment motor 31 to make the bidirectional threaded rod 32 rotate. Since the upper and lower threads of the bidirectional threaded rod 32 are opposite in direction, the sliding seat 33 slides in the inner cavity of the adjustment box 2. At this time, under the limiting constraint of the arc groove 21 on the sliding column 22, the upper and lower sliding seats 33 will move away from or towards the side wall of the bidirectional threaded rod 32 at the same time, so that the distance between the two flattening rollers 4 changes. At this time, the gap between the two flattening rollers 4 will change, so that the whole device can be used for hot-rolled coils of different thicknesses, improving the practicality of the whole device.
[0026] Furthermore, the flattening mechanism 6 includes a flattening motor 61 fixedly mounted on the side wall of the top plate 5 via a frame, and a transmission rod 62 rotatably mounted in the middle of the inner cavity of the top plate 5. The output shaft end of the flattening motor 61 is fixedly connected to the transmission rod 62, and the transmission rod 62 is fixedly connected to the flattening roller 4.
[0027] A limiting groove 23 is provided on the left side wall of the regulating box 2. An extension rod 24 is slidably installed in the inner cavity of the limiting groove 23 and is fixedly connected to the top plate 5.
[0028] It should be noted that the user can start the flattening motors 61 on the upper and lower sides, so that the transmission rod 62 drives the two flattening rollers 4 to rotate in opposite directions. At this time, when the hot-rolled coil passes through the flattening rollers 4, the hot-rolled coil can be continuously conveyed and flattened under the friction of the flattening rollers 4, so that the whole device can realize the function of flattening the hot-rolled coil.
[0029] Furthermore, the coating mechanism 7 includes a liquid pump 71 fixedly installed on the left side of the front end face of the top plate 5, and a connecting ring 72 rotatably installed on the side wall of the transmission rod 62. The transmission rod 62 is hollow, and an opening 621 is provided on the side wall of the transmission rod 62 in the inner cavity of the connecting ring 72.
[0030] The inner cavity of the flattening roller 4 is hollow. The flattening roller 4 is connected to the transmission rod 62. A coating nozzle 41 is fixedly installed on the side wall of the flattening roller 4. The side wall of the liquid pump 71 is connected to the connecting ring 72 through the liquid inlet pipe 711.
[0031] It should be noted that when the flattening rollers 4 on the upper and lower sides are rotating continuously, the user can start the liquid pump 71 to introduce rust-preventive liquid from the outside, which enters the connecting ring 72 through the liquid inlet pipe 711, then enters its inner cavity through the opening 621 on the transmission rod 62, and finally enters the flattening roller 4 and is sprayed out from the coating nozzle 41. In conjunction with the other smooth surfaces of the flattening roller 4, the hot-rolled coil can be flattened and rust-preventive treatment can be performed at the same time, reducing the production steps of the hot-rolled coil and thus greatly improving the production efficiency of the hot-rolled coil.
[0032] Working principle:
[0033] The user can start the adjustment motor 31 to make the bidirectional threaded rod 32 rotate. Since the upper and lower threads of the bidirectional threaded rod 32 are opposite, the sliding seat 33 slides in the inner cavity of the adjustment box 2. At this time, under the limiting constraint of the arc groove 21 on the sliding column 22, the upper and lower sliding seats 33 will move away from or towards the side wall of the bidirectional threaded rod 32 at the same time, so that the distance between the two flattening rollers 4 changes. At this time, the gap between the two flattening rollers 4 will change, so that the whole device can be used for hot-rolled coils of different thicknesses, improving the practicality of the whole device.
[0034] Users can start the flattening motors 61 on the upper and lower sides to make the transmission rod 62 drive the two flattening rollers 4 to rotate in opposite directions. At this time, when the hot-rolled coil passes through the flattening rollers 4, the hot-rolled coil can be continuously conveyed and flattened under the action of friction of the flattening rollers 4, so that the whole device can realize the function of flattening the hot-rolled coil.
[0035] As the flattening rollers 4 on both the upper and lower sides rotate continuously, the user can start the liquid pump 71 to introduce rust-preventive liquid from the outside. The liquid enters the connecting ring 72 through the liquid inlet pipe 711, then enters its inner cavity through the opening 621 on the transmission rod 62, and finally enters the flattening roller 4 and is sprayed out from the coating nozzle 41. In conjunction with the other smooth surfaces of the flattening roller 4, the hot-rolled coil can be flattened while rust prevention is performed, reducing the production steps of the hot-rolled coil and thus greatly improving the production efficiency of the hot-rolled coil.
[0036] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
