Description

Technical Field

[0001] The present invention relates to the technical field of strip tension leveling, and specifically to a double-tension and double-leveling continuous production device and a tension leveling process based on an extremely thin bright strip. Background Art

[0002] During the production process of strip steel, straightening is required. Due to the small thickness of the extremely thin bright strip steel, it is very difficult to straighten it only by a roller straightening machine. While a stretch-bending straightening machine can make the thin plate generate longitudinal and transverse deformations simultaneously, thereby fully improving the flatness and material properties of the thin plate. Among them, the stretch-bending straightening machine, abbreviated as the tension leveling machine, is a new type of straightening equipment developed to meet the high requirements for the flatness of strip materials. It combines the advantages of a roller straightening machine and a stretch straightening machine. Its working characteristic is that under the combined action of the tension of the tension rollers and the continuous alternating repeated bending of the bending rollers, the strip steel generates plastic elongation to obtain strip steel straightening. It can eliminate ternary shape defects such as camber, edge waviness, and sickle bend of the strip steel, significantly improving the shape quality and being applicable to continuous production lines.

[0003] After retrieval, it is found that the tension leveling machines disclosed in the authorized publication number CN101767126B and the tension leveling machines disclosed in the authorized publication number CN212598053U. In the above two technical solutions, two tension rollers are arranged at both the inlet and outlet of the strip steel, so that the strip steel moves along an S-shaped path when passing through, and a speed difference is generated between the inlet strip and the outlet strip through motor drive, thereby generating the required tension. The above two technical solutions both work together through two tension rollers at the inlet and outlet of the strip steel to achieve the purpose of double-tension and double-leveling, improving the accuracy and stability of straightening.

[0004] However, the applicant found that when the strip steel is straightened by the tension rollers, bending rollers, and straightening rollers, it will rub against the above-mentioned roller bodies, which will cause the temperature of the roller bodies to rise. Due to continuous production, the temperature will gradually increase. When the temperature is too high, it will affect the straightening accuracy and effect of the roller bodies, and it will also easily affect the material properties of the extremely thin bright strip steel. For example, the authorized publication number CN211052205U discloses a stainless steel coil stretch leveling device. The cooling device in this technical solution includes several water inlet pipes; water inlet pipes are arranged inside the upper straightening roller, lower straightening roller, upper bending roller, and lower bending roller. By setting the cooling device, it can cool the stainless steel coil during operation, reduce the heat generated during straightening, and thus reduce the defective rate of the stainless steel coil.

[0005] However, in the prior art during the straightening process, the cooling effect by setting a water inlet pipe inside the roller body is not good, and it is impossible to cool the roller body comprehensively. Moreover, due to the different widths of the steel strips, the temperature in the middle of the roller body is generally on the high side, while the temperature at both ends is on the low side. If the cooling water in the water inlet pipe does not flow, it will cause a problem that the cooling effect in the middle of the roller body is not good. Therefore, the prior art still requires the pump to work continuously to ensure the flow of the cooling water in the water inlet pipe. However, if the pump works continuously, the usage cost is relatively high. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a double-drawing and double-straightening continuous production equipment and a drawing and straightening process based on an extremely thin bright steel strip, and solves the problems existing in the above-mentioned prior art.

[0009] Preferably, the roller barrel component includes a roller barrel, through holes are arranged on both the front and rear sides of the roller barrel, and a temperature sensor I is arranged on the front side of the roller barrel.

[0010] Preferably, the roller shaft component includes a roller shaft.

A flow groove is arranged on the front side of the roller shaft, and holes located inside the roller barrel are evenly arranged on the flow groove. The front and rear sides of the roller shaft are respectively connected to bearing seats I and II, and driving bevel gears are evenly arranged on the outer wall of the roller shaft.

[0011] Preferably, the water delivery assembly includes a support bearing connected to the inner wall of the flow tank, and a water delivery pipe is connected to the support bearing; the water pumping assembly includes a water pumping pipe, the water pumping pipe is of an L-shaped structure, and a connecting bearing and a fixed bearing are respectively arranged at the front and rear ends of the water pumping pipe. The rear end of the roller shaft is connected to both the connecting bearing and the fixed bearing, and the diameter of the rear end of the roller shaft is smaller than the inner diameter of the water pumping pipe. A connecting pipe is connected to the top of the water pumping pipe, and a fixed rod fixedly connected to the second bearing seat is arranged on the connecting pipe.

[0012] Preferably, the detection assembly includes a mounting plate located in front of the connecting rod. The mounting plate is located below the roller shaft, and the front end of the mounting plate is inclined upward. The front end of the mounting plate is connected to the first bearing seat, and a liquid level sensor and a second temperature sensor located inside the roller are arranged on the mounting plate.

[0013] Preferably, the stirring assembly includes a rotating pipe connected to the mounting plate through a bearing. A driven bevel gear meshing with the driving bevel gear is arranged on the rotating pipe. Stirring rods and stirring blades matching the inner wall of the roller are arranged on the rotating pipe. A bubble generating device is arranged inside the rotating pipe.

[0014] Preferably, the support assembly includes two cross rods. Both cross rods are located between adjacent rotating pipes. Three rotating shafts are connected to the opposite sides of the two cross rods through bearings. Support wheels are arranged in the middle of the three rotating shafts. The three support wheels are distributed along an arc, and all three support wheels are in contact with the bottom of the inner wall of the roller. Turning plates are evenly arranged in the circumferential direction on the front and rear sides of the support wheels.

[0016] The double drawing and straightening continuous drawing and straightening process based on ultra-thin bright strip steel specifically includes the following steps:

[0018] Step 2: Detect the temperature of each roller mechanism. When the temperature rises, send cooling water through the water supply component, detect the water volume through the detection component, so that there is cooling water at the lower position inside the roller assembly. The friction generated when the steel strip passes can drive the rotation of the roller assembly and the roller shaft assembly, so that the roller assembly can be in full contact with the cooling water. At the same time, the roller shaft assembly drives each stirring component to stir the cooling water, so that the cooling water inside the roller assembly flows;

[0019] Step 3: Detect the temperature of the cooling water through the detection component. When the temperature of the cooling water is too high, pump away the cooling water through the pumping component, and then send in new cooling water through the water supply component to continue cooling.

[0021] The present invention provides a double-drawing and double-leveling continuous production device and a leveling process based on an extremely thin bright steel strip.

[0022] Compared with the prior art, it has the following beneficial effects:

[0023] 1. For the double-drawing and double-leveling continuous production device and leveling process based on an extremely thin bright steel strip, the cooling water is directly introduced into the roller. When the roller rotates, it can ensure full contact with the roller, and thus can cool the roller comprehensively. Moreover, through the water supply component and the pumping component, the replacement of the cooling water can be completed without affecting the rotation of the roller to straighten the steel strip.

[0024] 2. For the double-drawing and double-leveling continuous production device and leveling process based on an extremely thin bright steel strip, when the roller drives the roller shaft to rotate, it can simultaneously drive each stirring component to stir, so that the cooling water inside the roller can flow and exchange, avoiding the situation that only the water temperature in the middle of the roller is high and the water temperatures on both sides are low. In this way, the middle position of the roller can be cooled better, and it is not necessary to always keep the cooling water flowing through the pump, thereby reducing the cost.

[0025] 3. For the double-drawing and double-leveling continuous production device and leveling process based on an extremely thin bright steel strip, through the support component, the mounting plate that is only unidirectionally connected on the detection component can be supported, and when the roller rotates, it can also drive the support wheel to rotate, thereby driving the turning plate to rotate, so that the cooling water can be turned up and down, and thus the effect of the cooling water flowing and exchanging inside the roller is better, and the cooling effect on the roller is also better.

[0026] 4. In the double-drawing and double-leveling continuous production equipment and leveling process based on an extremely thin bright strip steel, when the stirring assembly rotates, the universal balls on the mounting rod roll on the inclined end face, and thus can drive the movable block to move in and out of the fixed tube. When it moves downward into the fixed tube, it can compress the air in the fixed tube, causing the bubbles to discharge from the bottom of the rotating tube, thereby increasing the bubbles in the cooling water. The bubbles move to the liquid surface and burst, increasing the heat exchange area between the cooling water and the outside air, thereby reducing the heating rate of the cooling water and extending the service life of the cooling water.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Refer to Figures 1-10 , the present invention provides the following two technical solutions:

[0040] The first embodiment: A double-drawing and double-straightening continuous production equipment for ultra-thin bright strip steel, including a machine body 1, a plurality of roller mechanisms 2, and a controller 3 provided on the machine body 1. The controller 3 is electrically connected to the electrical components in the text for convenient control. Tension mechanisms 4 are provided on both sides of the machine body 1. The tension mechanism 4 is composed of two roller mechanisms 2 and a driving motor for driving the rotation of the roller mechanism 2. A bending mechanism 5 and a straightening mechanism 6 are sequentially arranged on the machine body 1 from right to left between the two tension mechanisms 4 on both sides. The bending mechanism 5 is composed of two rows of upper and lower roller mechanisms 2 and a first hydraulic cylinder 7 connected to the upper row of roller mechanisms 2. The straightening mechanism 6 is composed of two rows of upper and lower roller mechanisms 2 and a second hydraulic cylinder 8 connected to the upper row of roller mechanisms 2. The first hydraulic cylinder 7 and the second hydraulic cylinder 8 are used to drive the connected roller mechanisms 2 to lift and lower;

[0041] The roller body mechanism 2 includes a detection component 27, a roller component 21, and a roller shaft component 22 connected to the roller component 21. On both sides of the roller shaft component 22, a first bearing block 23 and a second bearing block 24 are respectively connected. A water supply component 25 and a water pumping component 26 are connected to the roller shaft component 22. A number of stirring components 28 are drivingly connected to the roller component 21, and a number of support components 29 are connected to the detection component 27.

[0042] The roller component 21 includes a roller 211. Through holes 212 are provided on both the front and rear sides of the roller 211. The through holes 212 do not affect the subsequent rotation of the roller 211 around the mounting plate 271 and the water suction pipe 261. A first temperature sensor 213 is provided on the front side of the roller 211. The first temperature sensor 213 can be powered by setting a power supply on the roller 211, so that it is not hindered when following the rotation of the roller 211. The first temperature sensor 213 is used to detect the temperature of the roller 211.

[0043] The roller shaft component 22 includes a roller shaft 221. Connecting rods 222 connected to the inner wall of the roller 211 are evenly circumferentially arranged on the rear side of the outer wall of the roller shaft 221, so that when the roller shaft 221 rotates, it rotates synchronously with the roller 211 through the connecting rods 222. A flow groove 223 is provided on the front side of the roller shaft 221. Through channels 224 located inside the roller 211 are evenly provided on the flow groove 223. The front and rear sides of the roller shaft 221 are respectively connected to the first bearing block 23 and the second bearing block 24. Driving bevel gears 225 are evenly arranged on the outer wall of the roller shaft 221.

[0044] The water supply component 25 includes a support bearing 251 connected to the inner wall of the flow groove 223. A water supply pipe 252 is connected to the support bearing 251. When the roller shaft 221 rotates, the water supply pipe 252 can be made not to rotate along with it through the support bearing 251, so that the water supply pipe 252 can be fixed by connecting an external pipeline to the outside of the water supply pipe 252; the water pumping component 26 includes a water suction pipe 261. The water suction pipe 261 has an L-shaped structure, and a connecting bearing 262 and a fixed bearing 263 are respectively provided at the front and rear ends of the water suction pipe 261. The rear end of the roller shaft 221 is connected to both the connecting bearing 262 and the fixed bearing 263, and the diameter of the rear end of the roller shaft 221 is smaller than the inner diameter of the water suction pipe 261. A connecting pipe 264 is connected to the top of the water suction pipe 261. When the roller shaft 221 rotates, the water suction pipe 261 is made not to rotate along with it through the connecting bearing 262 and the fixed bearing 263, so that the bottom of the water suction pipe 261 can always be inserted into the cooling water. When pumping water, the cooling water in the roller 211 is pumped away through the water suction pipe 261 and then through the connecting pipe 264. In order to improve the stability of the water suction pipe 261, a fixing rod 265 fixedly connected to the second bearing block 24 is provided on the connecting pipe 264.

[0045] The detection component 27 includes a mounting plate 271 located on the front side of the connecting rod 222, so that the rotation of the connecting rod 222 is not obstructed by the mounting plate 271. The mounting plate 271 is located below the roller shaft 221, and the front end of the mounting plate 271 is inclined upward, which can prevent the cooling water falling from the hole 224 from flowing along the mounting plate 271 to the outside of the roller 211. The front end of the mounting plate 271 is connected to the first bearing seat 23, which can fix the mounting plate 271 unidirectionally. A liquid level sensor 272 and a second temperature sensor 273 located inside the roller 211 are arranged on the mounting plate 271, which are used to detect the water volume and water temperature of the cooling water inside the roller 211, and avoid the water volume being higher than the through hole 212 when water is supplied.

[0046] The stirring component 28 includes a rotating pipe 281 connected to the mounting plate 271 through a bearing. A driven bevel gear 282 meshed with the driving bevel gear 225 is arranged on the rotating pipe 281. Stirring rods 283 and stirring blades 284 matching the inner wall of the roller 211 are arranged on the rotating pipe 281, which can better stir the cooling water near the inner wall of the bottom of the roller 211. A bubble generating device 285 is arranged inside the rotating pipe 281.

[0047] The support component 29 includes two cross rods 291. Both of the two cross rods 291 are located between two adjacent rotating pipes 281. Three rotating shafts 292 are connected to the opposite sides of the two cross rods 291 through bearings. Support wheels 293 are arranged in the middle of the three rotating shafts 292. The three support wheels 293 are distributed along an arc, and all the three support wheels 293 are in contact with the bottom inner wall of the roller 211, which can support the unidirectional mounting plate 271 and improve its stability. Turning plates 294 are evenly arranged in the circumferential direction on the front and rear sides of the support wheels 293. When the roller 211 rotates, the support wheels 293 rotate accordingly, driving the turning plates 294 to rotate, so that the cooling water can be stirred up and down.

[0048] The second implementation mode is mainly different from the first implementation mode in that: the bubble generating device 285 includes a mounting bearing 2851 arranged at the bottom of the inner wall of the rotating pipe 281. A fixed pipe 2852 is arranged on the mounting bearing 2851. An inverted T-shaped rod 2853 is arranged at the bottom of the inner wall of the fixed pipe 2852. An inverted L-shaped rod 2854 connected to the mounting plate 271 is arranged on the inverted T-shaped rod 2853. When the rotating pipe 281 rotates, through the mounting bearing 2851, the inverted T-shaped rod 2853 and the inverted L-shaped rod 2854, the fixed pipe 2852 does not need to rotate, and cooling water will also enter the fixed pipe 2852. A slide rail 2855 is arranged on the fixed pipe 2852. A return spring 2856 is arranged on the slide rail 2855. The return spring 2856 is slidably connected to a slider 2857 slidably connected to the slide rail 2855. A movable block 2858 slidably sleeved on the inverted T-shaped rod 2853 is arranged on the slider 2857. An inclined cutting end face 2859 is arranged at the top of the movable block 2858. A universal ball 28510 is adhesively connected to the inclined cutting end face 2859. The universal ball 28510 is movably connected to a mounting rod 28511. The mounting rod 28511 is connected to the inner wall of the rotating pipe 281. When the rotating pipe 281 rotates, the universal ball 28510 rotates and presses the movable block 2858. Under the action of the return spring 2856, the movable block 2858 can enter and exit the fixed pipe 2852.

[0049] For the double-drawing and double-leveling continuous straightening process based on an extremely thin bright strip steel, using the double-drawing and double-leveling continuous production equipment based on an extremely thin bright strip steel in the second implementation mode, the specific steps are as follows:

[0050] Step 1: Pass the steel strip along an S-shaped path through the roller 211 of the right-side tension mechanism 4, and successively pass through the rollers 211 of the bending mechanism 5 and the straightening mechanism 6 for bending and straightening. Finally, pass through the roller 211 of the left-side tension mechanism 4 and also pass out along the S-shaped path for straightening.

[0051] Step 2: The temperature of the roller 211 on each roller mechanism 2 is detected by the temperature sensor 1 213. When the temperature rises, cooling water flows through the water supply pipe 252 to the flow groove 223, and then falls into the roller 211 through the channel 224. The water volume is detected by the liquid level sensor 272 detection component on the detection component 27. When the water volume is about to exceed the bottom height of the through hole 212, the water supply is stopped, so that cooling water is stored in the lower position of the roller 211. The roller 211 is connected to the roller shaft 221 through the connecting rod 222, so that the friction generated when the steel belt passes can drive The roller 211 and the roller shaft 221 rotate, so that the roller 211 on the roller assembly 21 can be fully contacted with the cooling water, and at the same time, the roller shaft 221 on the roller shaft assembly 22 drives the active bevel gear 225 to rotate, so that the driven bevel gear 282 drives the rotating tube 281 to rotate on the mounting plate 271, and the cooling water can be stirred by the stirring rod 283 and the stirring blade 284, so that the internal cooling water flows and exchanges, and it is avoided that only the water temperature in the middle of the roller 211 is high and the water temperature on both sides is low. In this way, the middle position of the roller 211 can be better cooled, and there is no need to keep the pump machine running all the time. The cooling water can be kept flowing, thereby reducing the cost. The one-way mounted mounting plate 271 can be stably supported by the support wheel 293. When the roller 211 rotates, the support wheel 293 can be driven to rotate, thereby driving the flip plate 294 to rotate, so that the cooling water flips up and down, thereby improving the cooling water flow exchange effect inside the roller 211 and improving the cooling effect of the roller 211. When the rotating tube 281 rotates, the mounting rod 28511 drives the universal ball 28510 to roll on the beveled end surface 2859 of the movable block 2858, thereby improving the cooling effect of the roller 211. The movable block 2858 causes extrusion, and then cooperates with the return spring 2856 to drive the movable block 2858 to enter and exit the fixed tube 2852. When entering the fixed tube 2852 and moving downward, the air in the fixed tube 2852 can be compressed, so that the bubbles are moved out of the fixed tube 2852 and discharged from the bottom of the rotating tube 281, thereby increasing the bubbles in the cooling water. The bubbles move to the liquid surface and burst, so that the heat exchange area between the cooling water and the outside air is increased, thereby reducing the temperature rise rate of the cooling water, thereby extending the use time of the cooling water;

[0052] Step three: Detect the temperature of the cooling water through the temperature sensor 273 on the detection component 27. When the cooling water temperature is too high, the cooling water is pumped away through the pumping pipe 261 and the connecting pipe 264 on the pumping component 26, and then new cooling water is delivered through the water delivery pipe 252 at the water delivery component 25 to continue cooling. In both steps two and three, the function of delivering cooling water to the water delivery pipe 252 and pumping cooling water away through the connecting pipe 264 is achieved by a pump.
