Technical Field
[0001] This invention belongs to the technical field of corrugated rolling equipment for metal sheets, specifically relating to a high-efficiency rolling roll for low-curvature-multi-driven roller system composite plates. Background Technology
[0002] Corrugated rolling of sheet metal is a rolling technology that forms corrugations on the surface of sheet metal under external force. Compared with flat rolling, corrugated rolled sheet metal has better resistance to high pressure and corrosion, and is widely used in construction, machinery, aerospace and other fields. Its core requirements are ensuring uniform corrugation size, reducing surface defect rate, and balancing production efficiency and equipment compliance. Currently, the industry mainly uses corrugated roll surface structures for corrugated rolling equipment. Its basic principle is that the uneven surface of the rolls causes the sheet metal to form a preset corrugated shape under the extrusion of the roll system. However, existing corrugated rolling equipment has obvious technical defects. First, the contact friction between the work roll and the plate is mostly sliding friction, resulting in concentrated contact stress, uneven wear of the work roll, short service life, and frequent replacement of parts. Second, the movement state of the work roll during rolling is uncontrollable, which leads to restricted metal flow channels and easily causes local accumulation, bulges, or edge burrs, and cracks are easily generated on the surface of the plate. To solve the above problems, this invention designs a cam-driven work roll corrugated rolling device with a torsion spring reset mechanism. Through the coordinated mechanism of gear meshing driving the controllable rotation of the work roll and the torsion spring achieving precise reset, the metal flow state is optimized, wear is reduced, and rolling accuracy is improved. Summary of the Invention
[0003] In view of the common problems of severe wear of work rolls, easy cracking of plate surface, and poor corrugation accuracy in existing corrugated rolling equipment, the purpose of this invention is to provide a cam work roll corrugated rolling device with torsion spring reset mechanism. By optimizing the roller system structure and motion mechanism, the device achieves controllable self-rotation and precise reset of work rolls, reduces friction and wear, promotes uniform metal flow, and improves corrugation forming quality and equipment stability.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A low-curvature-multi-follower roll system composite plate high-efficiency corrugated roll is provided, comprising symmetrically arranged flat roll side components and corrugated side components, which together form a closed rolling channel for continuous corrugation forming of metal sheets; wherein, the flat roll side component includes a flat roll side center roll, a coupling, and a transmission gear; wherein, the two ends of the center roll are connected to a transmission shaft via a coupling, the transmission shaft is driven by a rotating motor, and synchronous rotation with the corrugated side center roll is achieved through the meshing of the transmission gear; the corrugated side component includes a corrugated side center roll, a cage, a cam-shaped work roll, a transmission gear, and an alloy steel gasket; wherein, the cage and the corrugated side center roll are detachably fixedly connected, the two ends of the cam-shaped work roll are axially positioned with the cage via bushings, and gears are fixedly installed at both ends of the cam-shaped work roll for meshing with intermittent gear rings; the inner surface of the alloy steel gasket is tangent to the side surface of the cam-shaped work roll, achieving radial positioning and radial load buffering of the cam-shaped work roll.
[0005] In the flat roll side assembly, the flat roll side center roll serves as a reference support for corrugated rolling, providing a uniform reverse constraint force to ensure that the sheet metal closely conforms to the cam profile of the corrugated side work roll.
[0006] In the corrugated side assembly, the cage consists of an inner ring and an outer ring. The inner ring has symmetrically arranged slots along the circumference at the end facing the cam-shaped work roller, and its inner wall has a torsion spring positioning groove for installing the torsion spring. The inner side of the outer ring is machined with a right-hand trapezoidal thread. By rotating the outer ring clockwise, the threaded surfaces of the outer ring and the inner ring can be tightly fitted to achieve axial positioning of the inner ring. The outer side of the outer ring has evenly arranged threaded holes along the circumference. Through the synergistic action of cylindrical bolts and set screws, the cage and the corrugated side center roller can be detachably and fixedly connected, ensuring connection rigidity.
[0007] The torsion spring is assembled in the slot of the inner ring of the cage; one end of the torsion spring is fixed to the torsion spring positioning groove on the inner wall of the slot, and the other end is fixedly connected to the boss at the end of the work roller shaft. In its natural state, it keeps the work roller in its initial circumferential position. When subjected to torsion, it stores elastic potential energy and drives the work roller to reset when the energy is released.
[0008] The outer circumferential surface of the cam-shaped work roller has a cam-shaped structure with an eccentricity of 5-10mm. The curvature radius of the cam working surface is matched with the preset corrugation radius to ensure that the corrugation is formed regularly.
[0009] The intermittent gear ring is detachably mounted on the support housing. The intermittent gear ring structure includes an annular base and tooth segments. The tooth segments of the intermittent gear ring are arranged circumferentially along the annular base, and their length corresponds to the front rolling zone. The non-tooth segments of the intermittent gear ring are smooth arc surfaces to avoid meshing interference in the rear rolling zone. The annular base of the intermittent gear ring is provided with several threaded holes along the circumferential direction. During assembly, the installation position of the tooth segments relative to the support housing can be calculated according to the rolling process requirements. After selecting the angle, the tooth segments are threadedly connected to the corresponding threaded holes by bolts to achieve the fixed assembly of the intermittent gear ring and the support housing, thereby obtaining front and rear rolling zones of different lengths to adapt to different rolling process requirements.
[0010] The alloy steel gasket is arranged radially along the cam-shaped work roll and is connected to the corrugated side center roll by fastening bolts; the inner surface of the alloy steel is tangent to the side surface of the cam-shaped work roll, thereby realizing the radial positioning and radial load buffering of the cam-shaped work roll and reducing local stress peaks; the alloy steel gasket is made of high-strength, high-wear-resistant, and fatigue-resistant alloy material, and the material selection is based on existing products.
[0011] The rotating motor drives the flat roller side center roller and the corrugated roller side center roller to rotate synchronously through a coupling and transmission gear. The corrugated roller side center roller drives the cage to revolve around the central axis, thereby driving the 36 cam-shaped work rollers to revolve synchronously.
[0012] When the metal sheet enters the rolling channel, it is first positioned by the center roll on the flat roll side, and then enters the front rolling zone. The gear at the end of the cam-shaped work roll shaft meshes with the tooth segment of the intermittent gear ring. Since the intermittent gear ring is fixedly connected to the support shell, the gear at the end of the cam-shaped work roll shaft rotates counterclockwise, which in turn forces the cam-shaped work roll to rotate counterclockwise while revolving around the sun. At this time, the torsion spring is twisted and stores elastic potential energy. As the cam-shaped work roll continues to revolve with the cage, when the sheet enters the post-rolling zone, the gear at the shaft end of the cam-shaped work roll disengages from the ring tooth section of the intermittent gear, and the torsion spring releases its elastic potential energy, driving the cam-shaped work roll to rotate in the opposite direction to reset. Since the work roll has a cam-shaped structure, its protruding end moves away from the sheet during the reset process, which increases the roll gap, expands the metal flow channel, avoids local accumulation and blockage of metal, and promotes uniform metal flow.
[0013] Compared with the prior art, the beneficial effects of this invention are as follows: In the pre-rolling zone stage, the work roll is driven to rotate counterclockwise by the meshing of gears and intermittent gear ring teeth, converting traditional sliding friction into rolling friction, significantly reducing frictional loss between the work roll and the sheet metal, while avoiding local overheating caused by sliding friction, extending the service life of the work roll and the stability of the rolled product performance, and significantly reducing work roll wear; the contour design of the given cam-shaped work roll is precisely matched with the preset corrugations, and the torsion spring reset mechanism ensures accurate work roll reset, avoiding corrugation deviation during the rolling process; the work roll has a cam-shaped structure, and during the reset process, its protruding end moves away from the sheet metal, making... The increased roll gap in the post-rolling zone expands the metal flow channel, effectively solving the problems of local accumulation, bulging, and edge burrs in corrugated rolled metal sheets, resulting in fuller and more regular wave formation. The intermittent gear ring used is detachable and circumferentially adjustable, and the cam parameters of the cam-shaped work roll can be designed according to different corrugation requirements. With the help of cages and torsion springs, it can be adapted to corrugated rolling of various wavelengths and amplitudes, simplifying the structure and making it highly versatile. By installing alloy steel shims between the corrugated side center roll and the cam-shaped work roll, radial impact loads can be absorbed, local stress concentration can be reduced, and rotational stability can be improved, further ensuring the consistency of corrugation accuracy in long-term rolling.

[0016] like Figure 1-7 As shown, a low-curvature-multi-driven-roll system composite plate high-efficiency rolling mill roll is provided, which specifically includes a corrugated side assembly 1 and a flat roll side assembly 2 arranged symmetrically. Both ends of the corrugated side assembly 1 and the flat roll side assembly 2 are fixedly connected to a support shell 3 and a reduction gearbox 4. Both ends of the corrugated side and the flat roll side are equipped with transmission gears 13.

[0017] like Figure 2 , 3 As shown, the corrugated side assembly 1 includes a corrugated side center roller 6, eight outer rings of the cage 7, two inner rings of the cage 8, thirty-six cam-shaped work rollers 9, a transmission gear 13, and an alloy steel gasket 12. The cage and the corrugated side center roller 6 are detachably fixedly connected. The two ends of the cam-shaped work rollers 9 are axially positioned with the cage through bushings 10. The cylindrical gear 11 is installed between the bushings 10 and the cam-shaped work rollers 9 and meshes with the intermittent gear ring 17 fixed on the frame, thereby driving the cam-shaped work rollers to rotate.
[0018] like Figure 4 As shown, the flat roller side assembly 2 includes a flat roller side center roller 16, a coupling 18, and a transmission gear 13. The two ends of the flat roller side center roller 16 are connected to the transmission shaft through the coupling 18. The transmission shaft is driven by a rotary motor 5. The rotary motor 5 drives the flat roller side center roller 2 and the corrugated side center roller 1 to rotate synchronously through the coupling 18 and the transmission gear 13. The corrugated side center roller 1 drives the cage to revolve around the central axis, thereby driving the 36 cam-shaped work rollers 9 to revolve synchronously. The inner side of the alloy steel gasket 12 is tangent to the side of the cam-shaped work roller 9, realizing the radial positioning and radial load buffering of the cam-shaped work roller 9. The inner side of the alloy steel gasket is tangent to the side of the cam-shaped work roller, thereby realizing the radial positioning and radial load buffering of the cam-shaped work roller and reducing the local stress peak. The alloy steel gasket is made of high-strength, high-wear-resistant, and fatigue-resistant alloy material. The material selection is based on existing products.
[0019] In the aforementioned flat roll side assembly, the flat roll side center roll serves as a reference support for corrugated rolling, providing a uniform reverse constraint force to ensure that the sheet metal closely conforms to the cam profile of the corrugated side work roll.
[0020] like Figure 3As shown, the cage consists of an inner ring and an outer ring; the inner ring 8 of the cage has symmetrically arranged slots 81 along the circumference at one end facing the cam-shaped work roller 9, and its inner wall has a torsion spring positioning groove for installing the torsion spring 14; one end of the torsion spring is fixed to the torsion spring positioning groove on the inner wall of the slot, and the other end is fixedly connected to the boss at the end of the work roller shaft. In its natural state, it keeps the work roller in its initial circumferential position; when subjected to torsion, it stores elastic potential energy; when the energy is released, it drives the work roller to reset, as shown. Figure 5 As shown; the inner side of the outer ring 7 of the cage is machined with a right-hand trapezoidal thread. By rotating the outer ring clockwise, the threaded surfaces of the outer ring and the inner ring of the cage can be tightly fitted, thereby achieving axial positioning of the inner ring of the cage; threaded holes 72 are evenly arranged circumferentially on the outer side of the outer ring of the cage. Through the synergistic action of cylindrical bolts and set screws, the cage and the corrugated side center roller are detachably fixedly connected, ensuring connection rigidity.
[0021] like Figure 6 As shown, the intermittent gear ring 17 is detachably mounted on the support housing. The structure of the intermittent gear ring 17 includes an annular base and tooth segments. The tooth segments of the intermittent gear ring 17 are arranged circumferentially along the annular base, and their length corresponds to the front rolling zone. The non-tooth segments of the intermittent gear ring 17 are smooth arc surfaces to avoid meshing interference in the rear rolling zone. The annular base of the intermittent gear ring 17 is provided with several threaded holes along the circumferential direction. During assembly, the installation position of the tooth segments relative to the support housing can be calculated according to the rolling process requirements. After selecting the angle, the tooth segments are threadedly connected to the corresponding threaded holes by bolts to achieve the fixed assembly of the intermittent gear ring 17 and the support housing 3, thereby obtaining front and rear rolling zones of different lengths to adapt to different rolling process requirements.
[0022] Please see Figure 1-7 As shown, the rolling process of a low-curvature-multi-follower roll system composite plate high-efficiency rolling texture roll includes the following steps: A1. Material preparation; Prepare metal sheets of AL1060 and Q235 materials required for composite processing, and complete the normalizing, oxide layer removal, tempering and bonding processes to ensure that the sheet surface is free of impurities and meets the flatness standards. A2. Adjustment; Based on the thickness and reduction of the metal sheet, as well as parameters such as the corrugation wavelength and amplitude, calculate the initial roll gap and the installation orientation of the tooth segment relative to the support shell; check the installation status of the torsion spring to ensure that the work roll maintains its initial circumferential position in its natural state; adjust the initial roll gap to match the thickness of the composite sheet; based on the calculated installation angle of the intermittent gear ring, install the intermittent gear ring to the support shell with bolts so that the tooth segment accurately corresponds to the front rolling zone; A3. Feeding; The processed composite plate is pushed into the rolling channel by the feeding device. The front end of the plate contacts the flat roll side center roll 16 and the cam-shaped work roll 9, and is gradually bitten into the roll gap under the action of extrusion and friction. A4. Pre-rolling zone stage; The sheet material enters the pre-rolling zone. The cylindrical gear 11 at the shaft end of the cam-shaped work roll 9 meshes with the tooth segment of the intermittent gear ring 17. The cam-shaped work roll 9 rotates counterclockwise, and the torsion spring 14 synchronously twists and stores energy. The combined effect of the revolution and rotation of the cam-shaped work roll 9 extrudes the sheet material through its cam-shaped profile, initially forming corrugations. Figure 7 As shown in Figures 19-20; A5. Post-rolling zone stage; As the sheet enters the post-rolling zone, the cylindrical gear 11 at the shaft end of the cam-shaped work roll 9 disengages from the intermittent gear ring 17. The torsion spring 14 releases energy, driving the cam-shaped work roll 9 to reset. The increased roll gap expands the metal flow channel, allowing the metal to uniformly fill the corrugated cavity and avoid localized defects. Figure 7 As shown; A6. Testing; After forming, the corrugated sheet is conveyed out of the corrugated rolling device by the discharge device. In subsequent processes, the wavelength, amplitude and surface quality of the corrugations are tested to ensure that they meet the preset requirements.
