Description

Technical Field

[0001] This invention relates to the technical field of sheet metal straightening equipment, specifically to an automatic cleaning anti-indentation aluminum sheet straightening device and straightening method. Background Technology

[0002] Aluminum sheet is a high-performance metallic material widely used in various fields due to its unique physical and chemical properties. Aluminum sheets are characterized by low density, high strength, strong corrosion resistance, good plasticity, and excellent electrical and thermal conductivity, making them highly favored in modern industrial production. For example, in the automotive manufacturing industry, aluminum sheets are widely used in the manufacture of body panels, engine hoods, doors, and other components due to their lightweight and high strength. However, in the production process of aluminum sheets, achieving ideal flatness is difficult due to the complexity of the manufacturing process. Taking the rolling process as an example, during the rolling process, aluminum sheets are prone to defects such as bending or twisting due to the combined effects of uneven stress distribution and differences in cooling rates. Subsequent production processes, such as stamping and welding of automotive parts, have extremely stringent requirements for the flatness of aluminum sheets. Therefore, straightening is crucial and indispensable to ensure that aluminum sheets can meet the precision requirements of subsequent processing.

[0003] For straightening, two rows of straightening rollers distributed vertically are usually used to apply a certain pressure to the aluminum plate to achieve the straightening effect. However, during the straightening process, due to the mechanical stress on the surface of the aluminum plate during processing, aluminum powder on the surface of the aluminum plate is easy to fall off and adhere to the straightening rollers. As the pressure is applied, the aluminum powder can easily cause indentations on the aluminum plate, resulting in poor straightening effect.

[0004] To address this, existing straightening machines are typically equipped with cleaning mechanisms to pre-clean the aluminum sheet surface before it enters the vertically distributed straightening rollers. A common cleaning method involves using brush rollers to wipe the aluminum sheet surface and remove the adhering aluminum powder. However, in actual use, aluminum powder easily accumulates on the brush rollers, and this residual powder can cause secondary contamination of the aluminum sheet, thus affecting the thoroughness of the cleaning. Although some straightening machines are also equipped with vacuum cleaners to remove powder from the brush rollers, the suction and transfer capabilities of the vacuum cleaners are limited due to the strong adhesion between some powder and the brush rollers, making it difficult to completely remove these stubborn powder particles, thereby limiting cleaning efficiency and quality. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic cleaning anti-indentation aluminum plate straightening device and straightening method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic cleaning anti-indentation aluminum plate straightening device includes a base, two upright plates fixed on the base, and an upper cover connected to the two upright plates, and further includes:

[0008] Multiple upper and lower rollers are rotatably installed between the two vertical plates and in the upper cover. Each vertical plate and the upper cover is provided with a set of power mechanisms. The two sets of power mechanisms are used to drive multiple upper rollers and multiple lower rollers to rotate synchronously, and the rotation directions of the upper rollers and lower rollers are opposite.

[0009] Two brush rollers are provided on one side of the base via an assembly mechanism and are arranged vertically. The brush rollers are provided with nylon bristle bundles and a cleaning auxiliary mechanism that can move along the brush roller axis. When the cleaning auxiliary mechanism moves along the brush roller axis, it can cause the nylon bristle bundles to bend and rebound.

[0010] As a further embodiment of the present invention: the two upright plates are arranged opposite to each other, and a rotating shaft is rotatably installed on each of the two upright plates. The upper cover is fixed to the two rotating shafts. A third hydraulic cylinder is also installed on the side of the upright plate, and the movable end of the third hydraulic cylinder is rotatably connected to the upper cover.

[0011] As a further embodiment of the present invention: a driven gear is fixed on the rotating shaft of each of the multiple lower rollers, and the power mechanism includes a worm gear rotatably mounted on the inner wall of the vertical plate, multiple worm wheels meshing with the worm gear, and a transmission gear is fixed on the rotating shaft of each worm wheel;

[0012] The inner wall of the vertical plate is also equipped with a first motor, the output end of which is connected to the worm gear, and each of the transmission gears meshes with two adjacent driven gears.

[0013] As a further embodiment of the present invention: the assembly mechanism includes two support plates fixedly installed on one side of the base and arranged opposite to each other. The support plates are provided with a sliding groove, and two mounting seats distributed vertically are slidably fitted in the sliding groove. The brush roller is rotatably installed between the two opposite mounting seats.

[0014] The support plate is further equipped with a first hydraulic cylinder, the movable end of which is fixed to the mounting base. The mounting base is also equipped with a second motor, the output end of which is connected to the rotating shaft of the brush roller.

[0015] As a further embodiment of the present invention: the cleaning auxiliary mechanism includes multiple sets of actuating components movably disposed on the brush roller, the multiple sets of actuating components being equidistantly distributed along the circumference, and each set of actuating components being connected to a set of elastic components disposed at the end of the brush roller, the elastic components cooperating with a limiting structure disposed on the mounting base.

[0016] As a further embodiment of the present invention: the actuating component includes a movable block disposed on the outer wall of the brush roller and capable of moving along the axial direction of the brush roller, and two horizontal columns respectively fixedly connected to both ends of the movable block. Multiple arc-shaped levers are fixedly disposed between the two horizontal columns, and the multiple arc-shaped levers are equidistantly distributed along the axial direction of the brush roller.

[0017] The distance between the arc-shaped lever and the outer wall of the brush roller is less than the length of the nylon bristle bundle. Two guide protrusions are formed on the movable block. The outer wall of the brush roller is provided with a guide groove that matches the guide protrusions. The guide protrusions extend into the guide grooves and are slidably connected to the brush roller.

[0018] As a further embodiment of the present invention: a plurality of cylindrical cavities are equidistantly arranged at one end of the brush roller along the circumference, and the elastic component includes a column body slidably disposed in the cylindrical cavity and a cylindrical spring disposed in the cylindrical cavity, one end of the cylindrical spring being connected to the inner wall of the cylindrical cavity and the other end being connected to the column body;

[0019] The column is fixed to the movable block via a connecting arm, and a ball bearing is provided at one end of the column located outside the cylindrical cavity.

[0020] As a further embodiment of the present invention: the limiting structure includes a limiting ring fixedly installed on the mounting base, the central axis of the limiting ring and the brush roller coincide, and the ball abuts against the side of the limiting ring away from the mounting base. The limiting ring also has a plurality of protrusions on the side facing the ball, and the two sides of the protrusions are provided with inclined surfaces.

[0021] As a further embodiment of the present invention: the base is further provided with a guide mechanism, the guide mechanism including a frame fixed on the base, two movable seats symmetrically slidably fitted on the frame, and two limiting wheels respectively rotatably installed on the two movable seats;

[0022] The limiting wheel has a conical concave surface in its circumference, and a second hydraulic cylinder is rotatably mounted on the frame. The movable end of the second hydraulic cylinder is hinged to the movable seat.

[0023] A method for straightening an aluminum plate, using the aforementioned aluminum plate straightening device, includes the following steps:

[0024] Step 1: The two limit wheels clamp the side of the aluminum plate.

[0025] Step two: Push the aluminum plate forward, with the two brush rollers moving closer together and contacting the surface of the aluminum plate;

[0026] Step 3: The brush roller rotates to clean the aluminum powder on the surface of the aluminum plate.

[0027] Step four: The aluminum plate enters between the upper and lower rollers, where the upper and lower rollers straighten the aluminum plate.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] This application uses two vertically distributed brush rollers with nylon bristle bundles on them. By controlling the two brush rollers to rotate synchronously but in opposite directions, the powder and debris on the surface of the aluminum plate are cleaned. Each brush roller is equipped with a set of cleaning auxiliary mechanisms. At the same time, a third hydraulic cylinder drives the upper cover to swing upward through the rotating shaft, which allows the multiple upper rollers installed on the upper cover to open, thus facilitating the staff to check the condition and perform maintenance work on the upper and lower rollers.

[0030] Furthermore, during the rotation of the brush roller, the multiple protrusions on the limiting ring cause the elastic component to drive multiple arc-shaped levers to reciprocate along the axial direction of the brush roller. The distance between the arc-shaped levers and the outer wall of the brush roller is set to be less than the length of the nylon bristle bundle. During the movement of the arc-shaped levers, the nylon bristle bundle will bend. Since the nylon bristle bundle itself is elastic, after the arc-shaped levers separate from the nylon bristle bundle, the nylon bristle bundle will rebound. The rebound action generated in this process is based on the principle of inertia, which causes the aluminum powder on the bristle bundle to be thrown away from the surface of the bristle bundle due to inertia. This inertial swing accelerates the separation of aluminum powder from the bristle bundle, significantly improving the cleaning effect, thereby ensuring the anti-indentation function during the straightening process of the aluminum plate and effectively improving the straightening quality of the aluminum plate.

[0031] In addition, before the aluminum plate passes through the two brush rollers, its sides can be clamped by two limiting wheels. The two limiting wheels can effectively limit the aluminum plate, ensuring that the aluminum plate moves along a fixed line during the straightening process and avoiding the problem of the aluminum plate deviating during the process.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0047] Please see Figures 1-12 In this embodiment of the invention, an automatic cleaning anti-indentation aluminum plate straightening device includes a base 1, two upright plates 2 fixed on the base 1, and an upper cover 3 connected to the two upright plates 2, and further includes:

[0048] Multiple upper rollers 4 and lower rollers 5 are rotatably installed between the two vertical plates 2 and in the upper cover 3. Each vertical plate 2 and the upper cover 3 is provided with a set of power mechanisms. The two sets of power mechanisms are used to drive multiple upper rollers 4 and multiple lower rollers 5 to rotate synchronously, and the rotation directions of the upper rollers 4 and the lower rollers 5 are opposite.

[0049] Two brush rollers 14 are provided on one side of the base 1 via an assembly mechanism and are distributed vertically. The brush rollers 14 are provided with nylon bristle bundles and a cleaning auxiliary mechanism that can move along the axial direction of the brush rollers 14. When the cleaning auxiliary mechanism moves along the axial direction of the brush rollers 14, it can cause the nylon bristle bundles to bend and rebound.

[0050] Please refer to it again. Figure 1 and Figure 2 The two upright plates 2 are arranged opposite each other, and a rotating shaft 201 is rotatably installed on each of the two upright plates 2. The upper cover 3 is fixed to the two rotating shafts 201. A third hydraulic cylinder 25 is also installed on the side of the upright plate 2. The movable end of the third hydraulic cylinder 25 is rotatably connected to the upper cover 3.

[0051] In practical use, by controlling the extension of the movable end of the third hydraulic cylinder 25, the third hydraulic cylinder 25 can drive the upper cover 3 to swing upward through the rotating shaft 201, thereby opening the multiple upper rollers 4, which facilitates the staff to check the status of the upper rollers 4 and the lower rollers 5 and perform maintenance work.

[0052] Since the two sets of power mechanisms have the same structure, the power mechanism provided on the vertical plate 2 (used to drive the multiple lower rollers 5 to rotate synchronously) will be described in detail.

[0053] Please refer to it again. Figure 4 and Figure 6 Each of the multiple lower rollers 5 has a driven gear 6 fixed on its rotating shaft. The power mechanism includes a worm 9 rotatably mounted on the inner wall of the vertical plate 2 and multiple worm wheels 10 meshing with the worm 9. Each of the worm wheels 10 has a transmission gear 7 fixed on its rotating shaft.

[0054] The inner wall of the vertical plate 2 is also equipped with a first motor 8, the output end of the first motor 8 is connected to the worm gear 9, and each of the transmission gears 7 meshes with two adjacent driven gears 6.

[0055] Specifically, during the straightening process of the aluminum plate, the first motor 8 drives the worm 9 to rotate, and then the worm 9 drives the worm wheel 10 and the transmission gear 7 to rotate. The transmission gear 7 can drive the lower roller 5 to rotate through the driven gear 6, so as to achieve the effect of multiple lower rollers 5 rotating synchronously.

[0056] Furthermore, since multiple worm gears 10 are provided, the worm 9 has multiple helical teeth. Because the worm 9 and worm gears 10 have a self-locking function, when the worm 9 is stationary, the worm gears 10 cannot be easily reversed by external force. This allows the upper roller 4 and lower roller 5 to maintain a stable position when the machine is stopped, preventing accidental rotation due to external forces and ensuring the safety and stability of the device. Secondly, this transmission method has a compact structure, enabling the transmission of large torque within a small space, resulting in a more rational structural design and smaller footprint. It also meets the requirement of applying a large straightening force to the upper roller 4 and lower roller 5 during the straightening process, effectively improving the quality and efficiency of aluminum plate straightening.

[0057] Please refer to it again. Figure 7 and Figure 8 The assembly mechanism includes two support plates 11 fixedly installed on one side of the base 1 and arranged opposite each other. The support plates 11 are provided with sliding grooves, and two mounting seats 12 distributed vertically are slidably fitted in the sliding grooves. The brush roller 14 is rotatably installed between the two opposite mounting seats 12. A first hydraulic cylinder 13 is also fixedly installed on the side of the support plate 11. The movable end of the first hydraulic cylinder 13 is fixed to the mounting seat 12. A second motor 15 is also installed on the side of the mounting seat 12. The output end of the second motor 15 is connected to the rotation shaft of the brush roller 14.

[0058] It should be further explained that the brush roller 14 is located on the inlet side of the aluminum plate. During operation, the first hydraulic cylinder 13 works and can drive the mounting seat 12 to slide on the support plate 11. Specifically, the two mounting seats 12 on the support plate 11 slide closer to each other, and then the distance between the two brush rollers 14 gradually shortens until the nylon bristle bundles on the two brush rollers 14 respectively contact the upper and lower parts of the aluminum plate to be straightened.

[0059] Subsequently, the second motor 15 operates, driving the brush roller 14 to rotate. It should be noted that the two brush rollers 14 rotate in opposite directions, with the upper brush roller 14 rotating in the same direction as the lower roller 5, and the lower brush roller 14 rotating in the same direction as the upper roller 4. This allows the nylon bristles to rub against the aluminum plate surface, brushing away aluminum powder and preventing it from easily transferring to the upper roller 4 and lower roller 5 during straightening. Aluminum powder tends to accumulate on the surfaces of the upper roller 4 and lower roller 5, and under pressure, this powder can easily cause indentations on the aluminum plate. Therefore, this device automatically cleans the aluminum powder on the upper and lower surfaces of the aluminum plate by setting two brush rollers 14 at the inlet, thus preventing indentations during straightening.

[0060] Please refer to it again. Figure 9 , Figure 10 as well as Figure 11 The cleaning auxiliary mechanism includes multiple sets of actuating components movably mounted on the brush roller 14. The multiple sets of actuating components are equidistantly distributed along the circumference, and each set of actuating components is connected to a set of elastic components located at the end of the brush roller 14. The elastic components cooperate with the limiting structure located on the mounting base 12.

[0061] It should be added that two vacuum cleaners 24 are installed on the side of the support plate 11, and the two vacuum cleaners 24 correspond to the two brush rollers 14 respectively. During the cleaning process, the vacuum cleaners 24 are used to absorb the aluminum powder shavings brushed off.

[0062] The actuating assembly includes a movable block 16 disposed on the outer wall of the brush roller 14 and movable along the axial direction of the brush roller 14, and two horizontal columns 26 respectively fixedly connected to both ends of the movable block 16. Multiple arc-shaped levers 27 are fixedly disposed between the two horizontal columns 26, and the multiple arc-shaped levers 27 are equidistantly distributed along the axial direction of the brush roller 14. The distance between the arc-shaped levers 27 and the outer wall of the brush roller 14 is less than the length of the nylon bristle bundle. Two guide protrusions 1601 are formed on the movable block 16. The outer wall of the brush roller 14 is provided with guide grooves 1401 adapted to the guide protrusions 1601. The guide protrusions 1601 extend into the guide grooves 1401 and are slidably connected to the brush roller 14.

[0063] During the straightening process of the aluminum plate, when the second motor 15 drives the brush roller 14 to rotate, the brush roller 14 can drive the movable block 16 to move together through the guide groove 1401 and the guide protrusion 1601. In addition, the guide groove 1401 and the guide protrusion 1601 also play a guiding role, so that the movable block 16 and the multiple arc-shaped levers 27 can only move along the axial direction of the brush roller 14.

[0064] Furthermore, regarding the movement of the movable block 16 and the multiple arc-shaped levers 27, when some of the bristles on the brush roller 14 detach from the aluminum plate, the elastic component connected to the arc-shaped lever 27 corresponding to this part of the bristles will cooperate with the limiting structure. Thus, this set of elastic components is triggered, causing the movable block 16 to drive the multiple arc-shaped levers 27 to move axially along the brush roller 14 via the two horizontal columns 26. Since the distance between the arc-shaped lever 27 and the outer wall of the brush roller 14 is less than the length of the nylon bristle bundle, the movement of the arc-shaped lever 27 will promote… The nylon bristle bundles are bent, and due to their inherent elasticity, the bristles rebound after the curved lever 27 separates from them (similar to an elastic sheet returning to its original shape after the external force is removed). This rebound, based on the principle of inertia, causes aluminum powder particles on the bristle bundles to be flung off the surface due to inertia. This inertial movement accelerates the separation of aluminum powder particles from the bristle bundles, facilitating the subsequent collection of aluminum powder particles by the vacuum cleaner 24. This effectively prevents secondary contamination of the aluminum plate by residual aluminum powder particles on the bristle bundles. Through this innovative design, the cleaning effect is significantly improved, thereby ensuring the anti-indentation function during the straightening process of the aluminum plate and effectively improving the straightening quality of the aluminum plate.

[0065] One end of the brush roller 14 is provided with a plurality of cylindrical cavities 1402 at equal intervals along the circumference. The elastic component includes a column 17 slidably disposed in the cylindrical cavity 1402 and a cylindrical spring disposed in the cylindrical cavity 1402. One end of the cylindrical spring is connected to the inner wall of the cylindrical cavity 1402, and the other end is connected to the column 17.

[0066] The column 17 is fixed to the movable block 16 via a connecting arm 18. A ball bearing 1701 is provided at one end of the column 17 located outside the cylindrical cavity 1402. The limiting structure includes a limiting ring 19 fixedly installed on the mounting base 12. The central axis of the limiting ring 19 and the brush roller 14 coincides, and the ball bearing 1701 abuts against the side of the limiting ring 19 away from the mounting base 12. The limiting ring 19 also has a plurality of protrusions 1901 on the side facing the ball bearing 1701, and inclined surfaces 1902 are provided on both sides of the protrusions 1901.

[0067] Specifically, during the rotation of the brush roller 14, the ball bearing 1701 rolls along the circumference of the limiting ring 19. When the ball bearing 1701 rolls onto the inclined surface 1902, it causes the column 17 to give way, that is, the column 17 slides toward the cylindrical cavity 1402. The cylindrical spring is compressed, and the column 17 drives the movable block 16 to move relative to the brush roller 14 through the connecting arm 18. That is, the movable block 16 drives multiple arc-shaped levers 27 to move along the axial direction of the brush roller 14 through two horizontal columns 26, so that the bristle bundles separated from the aluminum plate can bend and rebound, which plays a role in throwing away the residual aluminum powder.

[0068] Furthermore, the ball bearing 1701 passes through multiple protrusions 1901, and in conjunction with the rebound of the cylindrical spring, multiple arc-shaped levers 27 can perform multiple reciprocating movements along the axial direction of the brush roller 14. The arc-shaped levers 27 can repeatedly move the brush bristle bundle, improving the thoroughness of aluminum powder collection by the vacuum cleaner 24 and avoiding the problem of secondary pollution of the aluminum plate caused by aluminum powder residue on the brush bundle.

[0069] Please refer to it again. Figure 2 , Figure 5 as well as Figure 12 The base 1 is also provided with a guide mechanism, which includes a frame 20 fixed on the base 1, two movable seats 21 symmetrically slidably fitted on the frame 20, and two limiting wheels 22 respectively rotatably mounted on the two movable seats 21; the limiting wheels 22 are provided with a conical concave surface in the circumference, and a second hydraulic cylinder 23 is rotatably mounted on the frame 20, the movable end of the second hydraulic cylinder 23 being hinged to the movable seat 21.

[0070] It should be noted that the limiting wheel 22 is located on the side of the brush roller 14 away from the upper roller 4 and the lower roller 5. In actual processing, the aluminum plate to be processed first passes through the two limiting wheels 22. The second hydraulic cylinder 23 drives the movable seat 21 to move the limiting wheels 22, so that the two limiting wheels 22 act on the two sides of the aluminum plate respectively to clamp the aluminum plate and avoid the problem of the aluminum plate deflecting during the process.

[0071] Secondly, the conical concave surface provided on the limiting wheel 22 can meet the clamping and limiting of plates of different thicknesses, thereby improving the applicability of the device.

[0072] As another embodiment of the present invention, an aluminum plate straightening method is also proposed, which uses the aforementioned aluminum plate straightening device and includes the following steps:

[0073] Step 1: The two limiting wheels 22 clamp the sides of the aluminum plate.

[0074] Step 2: Push the aluminum plate forward, with the two brush rollers 14 moving closer to each other and contacting the surface of the aluminum plate;

[0075] Step 3: The brush roller 14 rotates to clean the aluminum powder on the surface of the aluminum plate.

[0076] Step four: The aluminum plate enters between the upper roller 4 and the lower roller 5, and the upper roller 4 and the lower roller 5 straighten the aluminum plate.

[0077] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0078] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
