Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold rolling technology of stainless steel plates, specifically to an oil scraping device in the cold rolling process of stainless steel plates. Background Technology
[0002] In the cold rolling process of stainless steel sheets, the use of lubricating oil is essential. It can effectively reduce the friction between the rolls and the stainless steel sheet, prevent surface damage, and improve rolling efficiency. However, after rolling, the lubricating oil remaining on the surface of the stainless steel sheet needs to be removed in time to avoid affecting subsequent processing steps or product quality. Traditional oil scraping devices usually adopt a fixed scraper structure. The spacing of the fixed scraper cannot be adjusted, making it difficult to adapt to stainless steel sheets of different thicknesses. For thinner stainless steel sheets, the scraper may not be able to fully adhere to the surface, resulting in lubricating oil residue. For thicker stainless steel sheets, excessive scraper pressure may cause excessive wear or scratches on the surface of the stainless steel sheet. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oil scraping device for the cold rolling process of stainless steel plates, comprising a frame, two sliding grooves on the front surface of the frame, and a mounting plate fixedly connected to the front surface of the frame. Two oil collection tanks are installed inside the frame, and a first motor is fixedly connected to the front surface of the frame. The drive end of the first motor passes through the front surface of the frame and is fixedly connected to a first spur gear. A second spur gear meshes with the bottom of the first spur gear. A first transmission shaft is fixedly passed through the inside of the first spur gear, and a second transmission shaft is fixedly passed through the inside of the second spur gear. A first cold rolling roller is fixedly sleeved on the outside of the first transmission shaft, and a second cold rolling roller is fixedly sleeved on the outside of the second transmission shaft. An oil scraper is mounted on the mounting plate, comprising a second motor, a first bracket, and a second bracket. The second motor is fixedly connected to the bottom of the mounting plate, and the drive end of the second motor passes through the mounting plate and is fixedly connected to the first bracket. One end of the first bracket is movably connected to the second bracket, and one end of the second bracket is movably connected to a first adjusting rod. One end of the first adjusting rod is fixedly connected to a round rod, and the bottom end of the round rod is fixedly connected to a second adjusting rod.
[0005] As a preferred embodiment of this utility model, both the first adjusting rod and the second adjusting rod have two guide rods running through their interiors. One end of each guide rod is fixedly connected to a scraper, and a spring is sleeved on the outside of the guide rod.
[0006] In a preferred embodiment of this invention, one end of the spring is fixedly connected to the first adjusting rod, and the other end of the spring is fixedly connected to the scraper.
[0007] As a preferred embodiment of this utility model, an anti-detachment block is fixedly connected to the top end of the guide rod, and the guide rod and the first adjusting rod are slidably connected.

[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] The oil scraper is driven by a second motor to move the first and second supports, causing the first and second adjusting rods to swing around the circular rod as a reference, thus achieving synchronous oil scraping of the top and bottom of the stainless steel plate. This dynamic oil scraping method not only improves the oil scraping efficiency but also ensures the complete removal of lubricating oil from the surface of the stainless steel plate. Through the cooperation of springs and guide rods, the scraper can automatically adjust the pressure according to the thickness of the stainless steel plate, ensuring that the scraper is always in close contact with the surface of the stainless steel plate. This flexible contact method avoids the problems of scratching the stainless steel plate due to excessive pressure or lubricating oil residue due to insufficient pressure caused by traditional fixed scrapers, significantly improving the oil scraping effect.

[0017] 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.
[0018] Please see Figures 1 to 4 This utility model provides an oil scraping device for the cold rolling process of stainless steel plates, including a frame 1. Two sliding grooves 11 are formed on the front surface of the frame 1, and a mounting plate 12 is fixedly connected to the front surface of the frame 1. Two oil collection tanks 2 are installed inside the frame 1, and a first motor 3 is fixedly connected to the front surface of the frame 1. The drive end of the first motor 3 penetrates the front surface of the frame 1 and is fixedly connected to a first spur gear 31. A second spur gear 32 meshes with the bottom of the first spur gear 31. A first transmission shaft 33 is fixedly passed through the inside of the first spur gear 31, and a second transmission shaft 34 is fixedly passed through the inside of the second spur gear 32. The outer surface of the first transmission shaft 33... A first cold rolling roll 35 is fixedly sleeved on the part of the second transmission shaft 34, and a second cold rolling roll 36 is fixedly sleeved on the outside of the second transmission shaft 34. An oil scraper 4 is installed on the mounting plate 12. The oil scraper 4 includes a second motor 41, a first bracket 42 and a second bracket 43. The second motor 41 is fixedly connected to the bottom of the mounting plate 12, and the drive end of the second motor 41 passes through the mounting plate 12 and is fixedly connected to the first bracket 42. One end of the first bracket 42 is movably connected to the second bracket 43, and one end of the second bracket 43 is movably connected to the first adjusting rod 44. One end of the first adjusting rod 44 is fixedly connected to a round rod 45, and the bottom end of the round rod 45 is fixedly connected to the second adjusting rod 46.
[0019] Furthermore, both the first adjusting rod 44 and the second adjusting rod 46 have two guide rods 47 running through their interiors. One end of the guide rod 47 is fixedly connected to a scraper 48, and a spring 49 is sleeved on the outside of the guide rod 47. Through the cooperation of the guide rod 47 and the spring 49, the scraper 48 can move flexibly on the top and bottom of the stainless steel plate to ensure uniform oil scraping effect and avoid damage to the surface of the stainless steel plate caused by rigid contact.
[0020] Furthermore, one end of the spring 49 is fixed to the first adjusting rod 44, and the other end of the spring 49 is fixed to the scraper 48. The elasticity of the spring 49 enables the scraper 48 to adapt to stainless steel plates of different thicknesses. Whether the stainless steel plate is thin or thick, it can effectively scrape off the lubricating oil, thus expanding the applicability of the device.
[0021] Furthermore, an anti-detachment block is fixed to the top of the guide rod 47 to prevent the guide rod 47 from detaching from the first adjusting rod 44, thus ensuring the stability of the structure. The guide rod 47 and the first adjusting rod 44 are slidably connected, which allows the guide rod 47 to move smoothly.
[0022] Furthermore, the round rod 45 passes through the mounting plate 12, and the round rod 45 and the mounting plate 12 are rotatably connected by bearings. The first adjusting rod 44 and the second adjusting rod 46 are slidably connected inside the two sliding grooves 11 respectively. The mounting plate 12 is located between the first adjusting rod 44 and the second adjusting rod 46. The rotation of the round rod 45 drives the first adjusting rod 44 and the second adjusting rod 46 to swing, so that the scraper 48 can cover the entire width of the stainless steel plate, ensuring that there are no dead angles in oil scraping. The sliding connection of the sliding grooves 11 further improves the flexibility and adaptability of the scraper 48, and plays a certain role in limiting and supporting the scraper 48 when it swings.
[0023] Furthermore, one end of the first drive shaft 33 is rotatably connected to the inner wall of the frame 1 via a bearing, and both ends of the second drive shaft 34 are rotatably connected to the two sides of the inner wall of the frame 1 via bearings. With the support of the bearings, the first drive shaft 33 and the second drive shaft 34 can efficiently transmit power, enabling the first cold rolling roll 35 and the second cold rolling roll 36 to work stably, thereby improving cold rolling efficiency and the quality of stainless steel plates.
[0024] Among them, the first motor 3 and the second motor 41 are both model YE2.
[0025] Working Principle: When using this device, the stainless steel plate is fed into the frame 1 between the first cold rolling roll 35 and the second cold rolling roll 36. After the first motor 3 starts, it drives the first spur gear 31 to rotate. The first spur gear 31 meshes with the second spur gear 32, driving the second spur gear 32 to rotate in the opposite direction. The first spur gear 31 drives the first cold rolling roll 35 to rotate through the first transmission shaft 33, and the second spur gear 32 drives the second cold rolling roll 36 to rotate through the second transmission shaft 34, thereby realizing the cold rolling process of the stainless steel plate. During the cold rolling process, lubricating oil is sprayed on the surface of the stainless steel plate to reduce friction. After rolling, the lubricating oil remaining on the surface of the stainless steel plate needs to be removed by the scraper 4. At this time, the two scrapers 48 are held and pulled in opposite directions, so that the stainless steel plate passes through the two scrapers 48. Then the two scrapers 48 are released, and the elastic force of the spring 49 makes the scrapers 48 stick tightly to the stainless steel plate. After the second motor 41 starts, it drives the first cold rolling roll 35 to rotate through the first transmission shaft 33. The first support 42 rotates, and the first support 42 drives the second support 43 to move through a movable connection. This, in turn, pushes the first adjusting rod 44 and the second adjusting rod 46 to swing around the round rod 45 as a reference. The first adjusting rod 44 and the second adjusting rod 46 slide along the slide groove 11 respectively, causing the scraper 48 to come close to the surface of the stainless steel plate. The scraper 48 is slidably connected to the first adjusting rod 44 and the second adjusting rod 46 through the guide rod 47. When the stainless steel plate is thin, the compression of the spring 49 decreases, and the pressure of the scraper 48 decreases. When the stainless steel plate is thick, the compression of the spring 49 increases, and the pressure of the scraper 48 increases. This flexible contact method avoids the problem of scratching the stainless steel plate or the problem of lubricating oil residue. The scraped lubricating oil flows into the two oil collection tanks 2 inside the frame 1 for centralized recycling and treatment. Through the above process, this device achieves efficient and uniform removal of lubricating oil from the surface of the stainless steel plate, significantly improving the oil scraping effect and the quality of the stainless steel plate.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
