Description

Technical Field

[0001] This utility model relates to the field of deflection correction technology, specifically to a deflection correction device for cold rolling of armor belts. Background Technology

[0002] During the cold rolling process of armored strip, the strip is prone to deviation due to factors such as poor incoming material shape and uneven rolling force. This not only affects product quality but may also scratch the equipment and cause production stoppage. Therefore, anti-deviation correction devices are crucial for ensuring continuous and stable production and yield.

[0003] Traditional straightening devices typically have roller sets on both sides and below the strip path. The strip is prevented from deviating by relying on the positional constraint between the straightening roller sets and the strip, thereby achieving the straightening effect.

[0004] However, existing straightening devices have certain limitations in use. Because they only have rollers on both sides and below the strip path, they lack effective constraint on the strip above. When the rolling speed increases or the strip tends to tilt upwards, it is prone to jumping and shifting due to insufficient support above, resulting in limited straightening effect. Furthermore, after long-term operation, the roller surfaces are prone to accumulating rolling oil and metal debris, which can easily scratch the strip surface and affect product quality. The fixed rollers above the strip can easily obstruct the device, resulting in narrow cleaning space and extremely inconvenient maintenance, affecting production efficiency and product quality stability. Therefore, a straightening device for armored strip cold rolling is proposed to solve the above problems. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides an anti-deviation correction device for cold rolling of armored strip. It effectively solves the problem that existing technologies only set roller groups on both sides and below the strip path, lacking effective constraint on the top of the strip. When the rolling speed increases or the strip has an upward tendency, it is very easy for it to jump and deviate due to insufficient support above, resulting in limited correction effect. Moreover, the fixed roller groups set above it can easily block the device, resulting in narrow cleaning space, extremely inconvenient maintenance operations, and affecting production efficiency and product quality stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an anti-deviation correction device for cold rolling of armored belts, comprising: A base and a set of straightening rollers mounted on the base, the set of straightening rollers consisting of lateral straightening rollers located on the left and right sides of the strip and a bottom straightening roller shaft located below the strip, and a straightening assembly disposed above the base 1, the straightening assembly including: The upper alignment roller and the connecting frame, wherein multiple sets of the upper alignment roller are rotatably connected to the lower part of the connecting frame by pins; The adjustment unit includes a support frame fixedly mounted on a base, a lifting drive structure, and a tilting structure.

A guide screw is fixedly connected to the output end of the drive motor, and the guide screw is threadedly connected to the support column. The tilting structure is mounted on the support frame and is used to adjust the application direction of the upper correction roller.

[0007] Preferably, multiple sets of guide screws are provided, and the multiple sets of guide screws are connected by multiple sets of transmission wheels and transmission belts.

[0008] Preferably, a crossbar is fixedly installed between multiple sets of support frames, and the crossbar is sleeved outside the transmission belt.

[0009] Preferably, a flip plate is rotatably connected to the outer wall of the support column near the bottom end via a pin, and the bottom of the flip plate is fixedly connected to the connecting frame.

[0010] Preferably, the flipping structure includes a fixed plate and a guide block. The fixed plate is fixedly installed at the bottom of the support frame.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] See attached document Figure 1-6 An anti-deviation correction device for cold rolling of armor belts, comprising: The base 1 and the straightening roller assembly 2 mounted on the base 1 form the basic support structure for the entire anti-deviation straightening device, providing a stable mounting platform for other components and ensuring the device can operate stably during the cold rolling production of armored strip, bearing the loads generated by various components and during operation. The straightening roller assembly 2 consists of lateral straightening rollers located on the left and right sides of the strip and a bottom straightening roller shaft located below the strip. When the strip shows a lateral deviation tendency during cold rolling, the lateral straightening rollers contact the strip and, through friction and positional constraint, prevent the strip from continuing to deviate and guide it back to the correct running trajectory. The bottom straightening roller shaft provides stable support for the strip through contact with it, ensuring that the strip runs smoothly in the vertical direction. A straightening component is installed above the base 1, which includes: The upper straightening roller 3 and the connecting frame 301 are connected by a pin shaft to the bottom of the connecting frame 301. The upper straightening roller 3 contacts the upper surface of the strip. When the strip shows an upward or jumping tendency, the upper straightening roller 3 applies positional constraint to the strip to prevent abnormal movement of the strip and keep the strip at the correct running height and position. The adjustment unit includes a support frame 4 fixedly mounted on the base 1, a lifting drive structure, and a flipping structure. The lifting drive structure includes a drive motor 5 fixedly mounted on the top of the support frame 4 and a support column 502 slidably connected to the bottom of the support frame 4. A guide screw 501 is fixedly connected to the output end of the drive motor 5. The guide screw 501 is threadedly connected to the support column 502. One end of the guide screw 501 is fixedly connected to the output end of the drive motor 5. When the drive motor 5 drives the guide screw 501 to rotate, due to the threaded engagement between the support column 502 and the guide screw 501, the support column 502 will move up and down along the axial direction of the guide screw 501, thereby driving the connecting frame 301 and the upper correction roller 3 to move up and down, which is convenient for adjustment according to the thickness of the strip to be used and improves applicability. The flipping structure is set on the support frame 4 and is used to adjust the application direction of the upper correction roller 3.

[0020] Two sets of guide screws 501 are provided, and the two sets of guide screws 501 are connected by two sets of transmission wheels 504 and transmission belts 505 to promote the synchronous rotation of the two sets of guide screws 501, so that the two sets of support columns 502 rise and fall synchronously, thereby promoting the smooth movement of the connecting frame 301 and the upper correction roller 3.

[0021] A crossbar 401 is fixedly installed between the two sets of support frames 4 to enhance the structural stability between the support frames 4. The crossbar 401 is sleeved on the outside of the transmission belt 505 to provide a certain degree of protection for the transmission belt 505.

[0022] A tilting plate 503 is rotatably connected to the outer wall of the support column 502 near the bottom via a pin. The bottom of the tilting plate 503 is fixedly connected to the connecting frame 301. When the support column 502 is raised or lowered, it will push and pull the tilting plate 503, thereby driving the connecting frame 301 and the upper correction roller 3 to rise and fall as a whole. At the same time, when the tilting plate 503 is subjected to lateral force, it will rotate around the upper hinge point, thereby changing the angle of the lower connecting frame 301.

[0023] The flipping structure includes a fixed plate 6 and a guide block 602. The fixed plate 6 is fixedly installed at the bottom of the support frame 4. An arc-shaped groove 601 is opened on the side of the fixed plate 6 near the support column 502. The guide block 602 is fixedly installed on the flipping plate 503 and is slidably connected in the groove 601. When the support column 502 rises and falls, it drives the flipping plate 503 to move. Since the guide block 602 is restricted in the arc-shaped groove 601, the flipping plate 503 cannot swing freely, but moves according to the arc-shaped path specified by the groove 601. This transforms the lifting drive into a controllable compound motion with angle changes, causing the upper correction roller 3 and the connecting frame 301 to rotate 90 degrees, so that there is a certain space between the devices, which facilitates subsequent cleaning.

[0024] The inner cavity of the support frame 4 is provided with a moving groove, and a moving block is slidably connected to the inner wall of the moving groove. The moving block is fixedly connected to the outer wall of the support column 502. By restricting the sliding of the moving block in the moving groove, the moving range and moving path of the support column 502 are limited.

[0025] Multiple sets of support columns 502 are provided, and the multiple sets of support columns 502 are symmetrically distributed on the top of the connecting frame 301 to promote the smooth lifting and lowering of the connecting frame 301 and the upper correction roller 3.

[0026] Working principle: In use, the drive motor 5 is started, which drives the guide screw 501 fixed thereto to rotate. Since the support column 502 is threadedly engaged with the guide screw 501, and the moving block on its outer wall is restricted in the moving groove of the inner cavity of the support frame 4, the support column 502 moves up and down along the axial direction of the guide screw 501. In order to maintain stability, the two sets of guide screws 501 are linked to achieve synchronous rotation through the transmission wheel 504 and the transmission belt 505. The crossbar 401 enhances the structural stability and protects the transmission belt 505. The lifting and lowering of the support column 502 is transmitted to the connecting frame 301 fixed to the bottom of the flip plate 503 through the hinged flip plate 503, thereby driving multiple sets of upper correction rollers 3 to achieve overall lifting and lowering to adapt to strips of different thicknesses. The adjusted upper correction rollers 3 work together with the correction roller group 2 on the base 1 that wraps the strip from the left and right sides and below to form an all-round constraint on the strip. When it is necessary to flip the upper alignment roller 3 and the connecting frame 301, the drive motor 5 drives the guide screw 501 to rotate, causing the support column 502 to move upward, which in turn causes the flipping plate 503 to move upward. At this time, the guide block 602 fixed on the flipping plate 503 slides along the slide groove 601 on the fixed plate 6. The guide block 602 slides to the arc of the slide groove 601. The inner wall of the arc of the slide groove 601 guides the guide block 602 to move towards the arc, thereby causing the flipping plate 503 to rotate to the side, which in turn causes the connecting frame 301 and the upper alignment roller 3 to rotate, making room for cleaning and maintenance.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
