Description

TECHNICAL FIELD

[0001] The utility model relates to stainless steel strip processing technical field especially relates to the flattening device of super thin stainless steel strip. BACKGROUND

[0002] In the production and processing field of stainless steel materials, super thin stainless steel strips are widely used in aerospace, precision instruments, electronic equipment and high-end construction due to their high strength, corrosion resistance and lightweight characteristics.

[0003] The traditional super thin stainless steel strip processing device comprises an upper group S roller frame, upper and lower roller boxes in a multi-roller straightening device, and is respectively provided with movable flattening and fixed flattening rollers, a lower group S roller, a transmission motor flattening roller and the like, when the stainless steel strip passes through the upper group S roller and enters the flattening roller box, the super thin stainless steel strip is physically deformed when it comes out of the flattening roller box, and will be wrinkled when it comes to the lower group S roller group, which affects the steel strip pattern, if a flattening device is installed at the outlet of the flattening roller box, the super thin stainless steel strip is unfolded and enters the lower group S roller system evenly, which can improve the processing effect of the super thin stainless steel strip.

[0004] However, in the production process of the stainless steel strip, due to the contact with various processing equipment, lubricants and environmental factors, a certain amount of oil stains will inevitably adhere to the surface of the stainless steel strip, which mainly comes from rolling oil, cooling liquid, dust in the air and small particles generated by equipment wear.

[0005] The existence of oil stains can significantly reduce the friction coefficient between the flattening roller and the surface of the stainless steel strip. In the flattening process, the flattening roller relies on the friction force with the surface of the steel strip to exert sufficient pressure to realize the flattening of the steel strip. However, as a lubricating medium, the oil stain reduces the direct contact area between the flattening roller and the steel strip, thereby reducing the friction force between them, making it difficult for the flattening roller to exert sufficient pressure on the steel strip. This insufficient pressure not only makes the steel strip unable to reach the expected flatness, but also may cause slippage during the flattening process, further damaging the surface quality of the steel strip. CONTENT OF THE UTILITY MODEL

[0006] In order to overcome the defects of the prior art pointed out above, the present inventors have made in-depth research and, after a lot of creative labor, completed the present utility model.

[0007] Specifically, the technical problem to be solved by the present utility model is to provide a flattening device for super thin stainless steel strips to solve the technical problem that the existence of oil stains can significantly reduce the friction coefficient between the flattening roller and the surface of the stainless steel strip.

[0008] To solve the above technical problems, the utility model provides the following technical scheme:

[0009] The flattening device for ultra-thin stainless steel strips comprises a U-shaped frame, wherein movable flattening rollers and fixed flattening rollers are respectively arranged upward and downward inside the U-shaped frame;

[0011] Winding rollers are rotatably installed on both sides of the top of the support plate, an oil-absorbing felt is arranged between the two winding rollers, and a pressing roller for bending and guiding the oil-absorbing felt is arranged in the middle of the bottom of the support plate.

[0012] As an improved technical solution, movable cavities are opened on both sides of the U-shaped frame, and lifting blocks are slidably installed inside the movable cavity, and the movable leveling roller is rotatably installed between the lifting blocks on both sides. An electric telescopic rod for driving the lifting blocks to rise and fall is fixed on the top of the U-shaped frame, and servo motors are fixedly installed on the shaft ends of the fixed leveling roller and the movable leveling roller.

[0013] As an improved technical solution, drive motors are fixed on both sides of the top of the support plate through pads, and the drive end of the drive motor is connected to the shaft end of the corresponding winding roller. When one of the two winding rollers is in a winding state, the other is in an unwinding state.

A cross-connecting plate is arranged between the movable ends of the two support plates, and the pressure roller is rotatably installed at the bottom of the cross-connecting plate through a bearing.

[0015] As an improved technical solution, wheel frames are fixed to the front and rear ends of the cross-connecting plate, and a limiting wheel is rotatably installed between the two wheel frames on the same side. At the same time, the oil-absorbing felt is located between the limiting wheel and the opposite surface of the cross-connecting plate.

[0016] As an improved technical solution, a lifting plate is fixed between the movable ends of the two electric telescopic rods. The lifting plate is slidably installed with a T-shaped rod through sliding holes opened on both sides of its top, and the cross-connecting plate is welded between the bottom ends of the two T-shaped rods. The vertical rod end of the T-shaped rod is located between the opposite surfaces of the lifting plate and the cross-connecting plate and is sleeved with a spring.

[0032] like Figures 1 to 4As shown together, this embodiment provides a flattening device for ultra-thin stainless steel strips, comprising a U-shaped frame 1, wherein a movable flattening roller 12 and a fixed flattening roller 11 are respectively arranged from top to bottom inside the U-shaped frame 1, and a stainless steel strip channel is formed between the opposing surfaces of the fixed flattening roller 11 and the movable flattening roller 12;

[0033] Two oil removal components 2 are installed at the feed end of the U-shaped frame 1 in an opposite state. The oil removal component 2 includes a support plate 21 welded to the feed end side of the U-shaped frame 1, and an inclined frame 25 is welded on the side of the support plate 21 facing the feed end. A plurality of electric telescopic rods 3 26 are fixed on the inclined frame 25, and a rubber scraper 27 is fixedly connected between the movable ends of the plurality of electric telescopic rods 3 26. The extension and retraction of the electric telescopic rod 3 26 can control the contact force between the rubber scraper 27 and the outer wall of the stainless steel belt, and the position of the rubber scraper 27 can also be adjusted according to the thickness of different stainless steel belts to ensure the cleaning effect of the rubber scraper 27 on the oil stains on the stainless steel belt. Rubber scrapers 27 are provided on the upper and lower surfaces of the stainless steel belt for scraping, and the double-sided cleaning of the oil stains on the stainless steel belt is more comprehensive;

[0034] Winding rollers 23 are rotatably mounted on both sides of the top of the support plate 21 , an oil-absorbing felt 29 is arranged between the two winding rollers 23 , and a pressing roller 28 for bending and guiding the oil-absorbing felt 29 is arranged in the middle of the bottom of the support plate 21 .

[0035] Rubber scrapers 27 are provided on the upper and lower surfaces of the stainless steel belt for scraping. After the rubber scraper 27 cleans the oil on the surface of the stainless steel belt, the stainless steel belt will pass through the upper and lower oil-absorbing felts 29, so that the two oil-absorbing felts 29 are in contact with the two surfaces of the stainless steel belt respectively. The oil on the surface of the stainless steel belt is adsorbed and cleaned again by the oil-absorbing felts 29. Through the double decontamination measures, the stainless steel belt can be effectively cleaned from both sides at the same time, ensuring the friction and sufficient pressure between the leveling roller and the stainless steel belt, thereby ensuring the leveling effect of the stainless steel belt.

[0036] like Figures 1 to 2 As shown together, in this embodiment, a movable cavity 14 is opened on both sides of the U-shaped frame 1, and a lifting block 15 is slidably installed inside the movable cavity 14, and the movable leveling roller 12 is rotatably installed between the lifting blocks 15 on both sides. An electric telescopic rod 13 is fixed to the top of the U-shaped frame 1, and the movable end of the electric telescopic rod 13 is located inside the movable cavity 14 and is connected to the top of the lifting block 15. Servo motors 16 are fixedly installed on the shaft ends of the fixed leveling roller 11 and the movable leveling roller 12. The servo motor 16 connected to the fixed leveling roller 11 is fixed on the U-shaped frame 1, and the servo motor 16 connected to the movable leveling roller 12 is fixed on the lifting block 15.

[0037] like Figure 3As shown, in this embodiment, drive motors 22 are fixed to both sides of the top of the support plate 21 through pads, and the drive end of the drive motor 22 is connected to the shaft end of the corresponding winding roller 23. When one of the two winding rollers 23 is in a reeling state, the other is in an unreeling state. When the oil-absorbing felt 29 is used to clean the oil stains on the stainless steel belt, one drive motor 22 drives the winding roller 23 to reel, and the other drive motor 22 drives the other winding roller 23 to unreel. Different areas of the oil-absorbing felt 29 can be adjusted to contact and remove oil from the stainless steel belt, so as to improve the cleaning effect of the oil-absorbing felt 29 on the oil stains on the stainless steel belt.

[0038] like Figures 3 and 4 As shown together, in this embodiment, two electric telescopic rods 24 are fixed on the support plate 21 and between the winding rollers 23 on both sides, and the movable end of the electric telescopic rod 24 is located below the support plate 21. A cross-connecting plate 285 is provided between the movable ends of the two support plates 21, and the pressure roller 28 is rotatably mounted on the bottom of the cross-connecting plate 285 through a bearing. The extension and retraction of the electric telescopic rod 24 can adjust the height of the pressure roller 28, which is used to adjust the adaptability of the position of the pressure roller 28 according to stainless steel belts of different thicknesses, and can also adjust the contact distance and pressure between the pressure roller 28 and the oil-absorbing felt 29.

[0039] like Figure 4 As shown, in this embodiment, wheel frames 284 are fixed to the front and rear ends of the cross-connecting plate 285, and a limiting wheel 283 is rotatably installed between the two wheel frames 284 on the same side. At the same time, the oil-absorbing felt 29 is located between the limiting wheel 283 and the opposite surface of the cross-connecting plate 285. The limiting wheel 283 serves to limit the oil-absorbing felt 29, which is beneficial to ensure the fit between the oil-absorbing felt 29 and the outer wall surface of the pressure roller 28.

[0040] like Figure 4 As shown, in this embodiment, a lifting plate 281 is fixed between the movable ends of the two electric telescopic rods 24, and the lifting plate 281 is slidably installed with a T-shaped rod 282 through sliding holes opened on both sides of its top, and the cross-connecting plate 285 is welded between the bottom ends of the two T-shaped rods 282, and the vertical rod end of the T-shaped rod 282 is located between the opposite surfaces of the lifting plate 281 and the cross-connecting plate 285, and a spring 286 is sleeved. When the pressure roller 28 contacts the stainless steel belt, the pressure roller 28 provides an upward force to the T-shaped rod 282, so that the cross-connecting plate 285 compresses the spring 286, thereby preventing the pressure roller 28 from contacting the stainless steel belt when it descends and contacts the stainless steel belt. The contact between the pressure roller 28 and the stainless steel belt is elastic contact, which has a protective effect on the stainless steel belt.

[0041] When in use, the electric telescopic rod 3 26 is extended to drive the rubber scraper 27 to move in the direction of the stainless steel belt, so that the rubber scraper 27 contacts the surface of the stainless steel belt. When the stainless steel belt moves, due to the contact between the rubber scraper 27 and its outer wall, the rubber scraper 27 plays the role of scraping off the oil stains on the outer wall of the stainless steel. At the same time, rubber scrapers 27 are provided on both the upper and lower surfaces of the stainless steel belt for scraping;

[0042] After the rubber scraper 27 cleans the oil stains on the surface of the stainless steel belt, the stainless steel belt passes through the upper and lower oil-absorbing felts 29, so that the two oil-absorbing felts 29 are in contact with the two surfaces of the stainless steel belt respectively, and the oil stains on the surface of the stainless steel belt are absorbed and cleaned again by the oil-absorbing felts 29;

[0043] When the oil-absorbing felt 29 is used to clean the oil stains on the stainless steel belt, one drive motor 22 drives the winding roller 23 to reel in, and another drive motor 22 drives another winding roller 23 to unreel. Different areas of the oil-absorbing felt 29 can be adjusted to contact and remove oil from the stainless steel belt, thereby improving the cleaning effect of the oil-absorbing felt 29 on the oil stains on the stainless steel belt.

[0044] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
