Description

Technical Field

[0001] The utility model relates to the technical field of straightening devices, in particular to a stainless steel strip straightening device for stainless steel production. Background Technique

[0002] When the steel coil is used in the factory, an uncoiler is needed for uncoiling. Since the steel strip is coiled on the steel coil for a long time, the steel strip uncoiled by the uncoiler often has irregular shapes and bends. It is necessary to apply external force to the steel strip by machinery to straighten the steel strip to ensure the normal use of the steel strip in the follow-up.

[0003] In the prior art, a professional roller straightening machine is commonly used to extrude and straighten the stainless steel strip. When straightening the steel strip, depending on the straightening force and the equipment temperature, lubricating oil sometimes needs to be added to reduce the friction between the straightening roller and the steel strip, reduce wear, and make the straightening process smoother; at the same time, it may also help with heat dissipation.

[0004] According to a Chinese patent with the application number 202220107680.7, a stainless steel strip straightening device for stainless steel production, a linkage mechanism is added during use so that lubricating oil can be sprayed while straightening the steel strip. However, when spraying lubricating oil, only one side of the steel strip can obtain the lubricating oil, and straightening generally uses straightening rollers for double-sided extrusion. With lubricating oil on only one side, the lubrication effect is poor. At the same time, this device uses a piston to spray lubricating oil, and the spraying of lubricating oil is intermittent, and its lubrication effect coverage is poor. Therefore, an improved stainless steel strip straightening device for stainless steel production is needed to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide a stainless steel strip straightening device for stainless steel production to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A stainless steel strip straightening device for stainless steel production, including a fixed frame, between which a number of straightening rollers are movably arranged through a rotating shaft. On one side of the surface of the fixed frame, a coating mechanism for applying lubrication is fixedly arranged. The coating mechanism includes a mounting frame, a first guide roller, a second guide roller, a storage pool, a third guide roller, and a steel strip. On one side of the surface of the fixed frame, a mounting frame is fixedly arranged. Between the mounting frames, a first guide roller is movably arranged through a rotating shaft. Between the first guide rollers on the mounting frames, a second guide roller is movably arranged through a rotating shaft. On one side of the lower end of the fixed frame, a storage pool is fixedly arranged. In the middle of the inner side of the storage pool, a third guide roller is movably arranged through a rotating shaft. The outer surfaces of the first guide roller, the second guide roller, and the third guide roller are sleeved with a steel strip.

[0007] Preferably, electric push rods are fixedly arranged on both sides of the surface of the storage tank. The movable end of the electric push rod is fixedly provided with a filling block. The filling block is arranged inside the storage tank. When the filling block is inside the storage tank, it can fill the space inside the storage tank, so that the liquid level of the lubricating oil inside the storage tank rises, and thus it can contact the steel strip passing through the lower end of the third guide roller to play a role in smearing the lubricating oil. If there is no need for lubricating oil, by extending the electric push rod, the filling block is lifted and separated from the inside of the storage tank, so that the liquid level of the lubricating oil drops, and thus the contact between the lubricating oil and the steel strip can be stopped, making the device easy to use.

[0008] Preferably, a bracket is fixedly arranged on the surface of the storage tank on one side of the electric push rod. A fixed frame is fixedly arranged on the bracket. The fixed frame is sleeved outside the steel strip. A scraper is fixedly arranged on the outer surface of the upper end of the fixed frame. By fitting the scraper on the outer surface of the steel strip, the excess lubricating oil on the surface of the steel strip can be scraped off, so that the excess lubricating oil can flow back into the storage bin under the action of gravity, thus preventing waste of excess lubricating oil.

[0009] Preferably, the scraper is made of rubber material, and the outer surface of the scraper fits with the outer surface of the steel strip. The rubber scraper can prevent scratching the surface of the steel strip.

[0010] Preferably, the steel strip passes between the straightening rollers. By the relative extrusion of the straightening rollers, the steel strip can be straightened to prevent the steel strip from being bent and uneven.

[0011] Preferably, lubricating oil is arranged inside the storage tank. Since the device is provided with the first guide roller, the second guide roller and the third guide roller, under the action of these three guide rollers, the steel strip can pass through the inside of the storage tank, and there is lubricating oil inside the storage tank. Thus, the steel strip can be quickly immersed in the lubricating oil, so that a lubricating oil film is fully and evenly attached to the surface of the steel strip. The addition effect of the lubricating oil is better and more uniform, which can facilitate the heat dissipation of the steel strip and prevent the steel strip from being scratched in subsequent processes.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. The present utility model is provided with the first guide roller, the second guide roller and the third guide roller. Under the action of these three guide rollers, the steel strip can pass through the inside of the storage tank, and there is lubricating oil inside the storage tank. Thus, the steel strip can be quickly immersed in the lubricating oil, so that a lubricating oil film is fully and evenly attached to the surface of the steel strip. The addition effect of the lubricating oil is better and more uniform, which can facilitate the heat dissipation of the steel strip and prevent the steel strip from being scratched in subsequent processes.

[0014] When the utility model is in use, the scraping plate is attached to the outer surface of the steel strip. In this way, when the steel strip moves upward after being immersed in the lubricating oil, the excess lubricating oil on the surface can be scraped off. Thus, the excess lubricating oil can flow back into the storage bin under the action of gravity, preventing the waste of excess lubricating oil. And when the lubricating oil is not needed during the use of this device, the electric push rod extends, causing the filling block to move upward and separate from the inside of the storage pool. This will cause the liquid level of the lubricating oil to drop, stopping the contact between the lubricating oil and the steel strip, making the device convenient to use.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a stainless steel strip straightening device for stainless steel production, including a fixed frame 12. A number of straightening rollers 2 are movably arranged between the fixed frames 12 through a rotating shaft. On one side of the surface of the fixed frame 12, a coating mechanism for applying lubrication is fixedly arranged. The coating mechanism includes a mounting frame 3, a first guide roller 4, a second guide roller 5, a storage pool 6, a third guide roller 7, and a steel strip 8. On one side of the surface of the fixed frame 12, a mounting frame 3 is fixedly arranged. The first guide roller 4 is movably arranged between the mounting frames 3 through a rotating shaft. The second guide roller 5 is movably arranged between the first guide rollers 4 between the mounting frames 3 through a rotating shaft. On one side of the lower end of the fixed frame 12, a storage pool 6 is fixedly arranged. In the middle of the inner side of the storage pool 6, a third guide roller 7 is movably arranged through a rotating shaft. The outer surfaces of the first guide roller 4, the second guide roller 5, and the third guide roller 7 are sleeved with a steel strip 8.

[0021] On both sides of the surface of the storage pool 6, electric push rods 9 are fixedly arranged. The movable ends of the electric push rods 9 are fixedly provided with filling blocks 10. The filling blocks 10 are arranged inside the storage pool 6. When the filling blocks 10 are inside the storage pool 6, the space inside the storage pool 6 can be filled, so that the liquid level of the lubricating oil inside the storage pool 6 rises. In this way, it can contact the steel strip 8 passing through the lower end of the third guide roller 7 to play the role of applying lubricating oil. If there is no need for lubricating oil, by extending the electric push rods 9, the filling blocks 10 are lifted and separated from the inside of the storage pool 6. In this way, the liquid level of the lubricating oil will drop, and the contact between the lubricating oil and the steel strip 8 can be stopped, making the device easy to use.

[0022] On the surface of the storage pool 6, on one side of the electric push rod 9, a bracket 11 is fixedly arranged. A fixed frame 12 is fixedly arranged on the bracket 11. The fixed frame 12 is sleeved outside the steel strip 8. On the outer surface of the upper end of the fixed frame 12, a scraper 13 is fixedly arranged. By fitting the scraper 13 on the outer surface of the steel strip 8, the excess lubricating oil on the surface of the steel strip 8 can be scraped off. In this way, the excess lubricating oil can flow back into the storage bin under the action of gravity, thus preventing waste of excess lubricating oil.

[0023] The scraper 13 is made of rubber material. The outer surface of the scraper 13 is mutually attached to the outer surface of the steel strip 8. The rubber scraper 13 can prevent scratching the surface of the steel strip 8.

[0024] The steel strip 8 passes through between the straightening rollers 2. By relatively squeezing the straightening rollers 2, the steel strip 8 can be straightened to prevent the steel strip 8 from being bent and uneven.

[0025] Lubricating oil is arranged inside the storage tank 6. Since the device is provided with a first guide roller 4, a second guide roller 5 and a third guide roller 7, the steel strip 8 can pass through the storage tank 6 under the action of the three guide rollers. The storage tank 6 contains lubricating oil, so the steel strip 8 can be quickly immersed in the lubricating oil, so that the surface of the steel strip 8 is fully and evenly covered with a lubricating oil film, and the effect of adding the lubricating oil is better and more uniform, thereby facilitating the heat dissipation of the steel strip 8 and preventing the steel strip 8 from being scratched in subsequent processes.

[0026] Working principle: When using this device, a first guide roller 4, a second guide roller 5 and a third guide roller 7 are provided. Under the action of these three guide rollers, the steel strip 8 can pass through the storage tank 6, and there is lubricating oil inside the storage tank 6, so that the steel strip 8 can be quickly immersed in the lubricating oil, so that the surface of the steel strip 8 is fully and evenly covered with a lubricating oil film, and the lubricating oil addition effect is better and more uniform, so that the heat dissipation of the steel strip 8 can be facilitated and the steel strip 8 can be prevented from being scratched in the subsequent processes;

[0027] When the device is used, the scraper 13 is attached to the outer surface of the steel belt 8, so that when the steel belt 8 penetrates the lubricating oil and moves upward, the excess lubricating oil on the surface can be scraped off, so that the excess lubricating oil can flow back into the storage bin under the action of gravity, thus preventing the waste of excess lubricating oil;

[0028] When the device is used, the electric push rod 9 is extended, so that the filling block 10 moves up and disengages from the storage tank 6, which will reduce the liquid level of the lubricating oil, thereby stopping the lubricating oil from contacting the steel belt 8, making the device easy to use.
