DETAILED DESCRIPTION

[0021] The following describes embodiments of the present invention in detail.

[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0025] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0026] In the manufacturing of garden facilities such as flower beds, landscape decorative components, and some architectural structures, sheet metal often needs to be processed into curved plates with specific curvatures to meet requirements for structural strength, load-bearing stability, or aesthetics. Existing technologies use general-purpose sheet metal bending equipment for this purpose, but most focus on optimizing the feed end without considering the discharge end, resulting in poor discharge stability and convenience.

[0027] For this reason, Figure 1As shown, the metal plate rolling forming device proposed in the present invention includes a machine base 100, a feed assembly 200 disposed on the machine base 100, a first rolling assembly 300 connected to the machine base 100 and located on the output side of the feed assembly 200, and a discharge guide assembly disposed on the machine base 100 and located on the output side of the first rolling assembly 300. The feed assembly 200 is used to horizontally support the metal plate 500, and the first rolling assembly 300 includes two first pressing rollers 310 arranged vertically at intervals. The two first pressing rollers 310 are radially opposed to each other to form a first arched channel 301, which is bent upward after the metal plate 500 passes through. Furthermore, the discharge guide assembly includes a first guide wheel 110, which is located on the upper side of the first arched channel 301 and is in rolling contact with the surface of the metal plate 500 to discharge the metal plate 500. It should be noted that the first arching channel 301 formed by the two vertically spaced first pressure rollers 310 can stably extrude and deform the metal plate 500, and efficiently arch the metal plate 500; in addition, the first guide wheel 110 in the discharge guide assembly, which is located on the upper side of the first arching channel 301 and rolls against the surface of the metal plate 500, can reduce friction damage and ensure that the metal plate 500 is stably discharged, thereby improving the overall processing quality and efficiency.

[0028] For example, metal sheet 500, such as a flowerbed tile, is a key component in the flowerbed structure. Its curved design not only impacts the overall aesthetics of the flowerbed but also directly affects drainage performance, structural stability, and service life. It is a core component in the manufacture of horticultural products. Currently, flowerbed products are increasingly miniaturized and refined, placing higher demands on the curvature of the flowerbed tile. However, existing technologies for curving flowerbed tiles primarily rely on a single roller pressing process, where a pair of rollers with a fixed spacing applies unidirectional pressure to the flowerbed tile, forcing it into a single curved structure. This traditional process has significant limitations. Firstly, the curvature that can be achieved in a single roller pressing process is limited, making it difficult to achieve large curvatures. This is particularly unsuitable for smaller flowerbed components that require higher curvatures. Since small flowerbeds require more precise curvatures for the flowerbed tile, traditional equipment cannot achieve sufficient curvature variation in a single forming process, resulting in products that fail to meet design requirements and affecting the overall aesthetics and structural stability of the flowerbed. On the other hand, the operation mode of the traditional equipment requires the operator to manually place the flower bed tile to be processed on the input side of the roller, and then manually collect the finished flower bed tile from the other side after processing. The operator needs to move to another position to collect the material, which has the problems of high labor intensity and low material collection efficiency. In this regard, in some embodiments of the present invention, such as Figures 2 to 5As shown, the machine base 100 is also connected to a second rolling assembly 400, which is located on the curved path of the first rolling assembly 300 to the metal plate 500. The second rolling assembly 400 includes two second pressing rollers 410 arranged at intervals in an oblique direction, and the two second pressing rollers 410 are radially opposed to each other to form a second arched channel 401 to bend downward after the metal plate 500 passes through, and transport the metal plate 500 back to one side of the feeding assembly 200 to unload the processed metal plate 500. It should be noted that, by setting up a systematic structure of the machine base 100, the feeding assembly 200, the first rolling assembly 300 and the second rolling assembly 400, the integrated functions of efficient and precise arch forming and convenient material collection of the metal plate 500 are realized, effectively solving the two major technical problems of insufficient curvature of the single rolling process and inconvenient material collection in the prior art. Among them, the synergistic effect of the integration of the first rolling assembly 300 and the second rolling assembly 400 is realized, and the efficient and precise double arch forming processing of the metal plate 500 such as the flower bed tile is realized, which is particularly suitable for the processing of the metal plate 500 with a longer length. On the one hand, it solves the technical bottleneck of insufficient curvature of the traditional single rolling process, and is particularly suitable for the production needs of flower bed assembly parts with smaller shapes and higher curvature. On the other hand, through the circulating conveying path of the metal plate 500 inside the device, the operator is saved from the tedious operation of placing the metal plate 500 on the input side of the roller and collecting it on the other side, which significantly reduces the labor intensity and improves the material collection efficiency, making the production process more coherent and efficient.

[0029] In some embodiments of the present invention, reference Figures 2 to 4 , the machine base 100 is provided with two first guide wheels 110, and the two first guide wheels 110 are between the first rolling assembly 300 and the second rolling assembly 400. The two first guide wheels 110 are arranged at intervals on the curved path of the metal plate 500, and the two first guide wheels 110 are respectively in contact with the two side surfaces of the metal plate 500 for guidance. On the one hand, this guide structure can prevent it from swinging left and right due to vibration or material elasticity when passing at high speed, thereby ensuring the accuracy of the upward arc forming, avoiding the arc asymmetry or superimposed deformation caused by offset, and significantly improving the quality and consistency of the two-way arch forming. On the other hand, the guide design of the two first guide wheels 110 effectively solves the technical problem that the metal plate 500 is prone to offset due to the lack of lateral constraints during the transition from the upward bending of the first arch channel 301 to the downward bending of the second arch channel 401, ensuring the path stability of the metal plate 500 during the conversion process, especially for metal plates 500 with smaller widths. Refer again Figure 4In some embodiments of the present invention, the metal plate 500 includes multiple concave arc portions 510 and multiple convex arc portions 520, which are arranged alternately. The two first guide wheels 110 are staggered and abut against either side of the same concave arc portion 510 to limit the widthwise displacement of the metal plate 500. Furthermore, this method fully utilizes the alternating concave and convex geometric characteristics of the metal plate 500 surface, achieving precise limitation of the widthwise displacement of the metal plate 500 through an asymmetric distribution of contact points. Compared to traditional symmetrical guiding methods, this method is more adaptable to local curvature variations in the metal plate 500 and effectively prevents distortion of small metal plates 500 due to insufficient rigidity during bidirectional rolling. At the same time, the staggered arrangement increases the guide channel between the two first guide wheels 110 for the metal plate 500 to enter. For example, the metal plate 500 can enter between the two first guide wheels 110 even if it is slightly deflected. Therefore, the metal plate 500 can better penetrate between the two first guide wheels 110 and avoid surface indentation damage caused by excessive extrusion. While ensuring guiding accuracy, the surface quality and forming smoothness of the metal plate 500 are improved, which is particularly suitable for the production of horticultural metal plates 500 with high precision requirements.

[0030] Similarly, in some embodiments of the present invention, reference Figures 2 to 4 The base 100 is provided with two second guide wheels 120. The two second guide wheels 120 are on the output side of the second rolling assembly 400. The two second guide wheels 120 are arranged at intervals on the curved path of the metal plate 500. The two second guide wheels 120 are respectively in contact with the two side surfaces of the metal plate 500 for guidance, thereby forming a closed-loop guide system from bending processing to material collection. This effectively solves the technical difficulty that the metal plate 500 is easily deviated from the preset path and returned due to inertial impact and gravity after completing downward bending and rebounding, ensuring that the metal plate 500 can accurately return to the preset material collection area on one side of the feeding assembly 200, avoiding the operation of manual secondary position adjustment, not only significantly reducing the labor intensity of the operator, but also reducing the risk of product collision and damage by reducing human intervention. At the same time, the inclination angle of the second guide wheel 120 can be optimized to provide progressive support force during the rebound stage of the metal plate 500, preventing arc rebound or shape distortion caused by excessive rebound speed, and further improving the dimensional stability and surface flatness of the final product. Optionally, similar to the action position of the first guide wheel 110 on the metal plate 500, the second guide wheel 120 is staggered and abuts against both sides of the same concave arc portion 510 to limit the displacement of the metal plate 500 in the width direction.

[0031] In some embodiments of the present invention, Figure 2 and Figure 3As shown, symmetrically arranged first mounting grooves 101 are provided on both sides of the machine base 100, and the first mounting grooves 101 are provided with a first length column 320, a first mounting block 330, a second length column 340, a second mounting block 350 and a first pressure rod 360 which are overlapped in sequence in the arrangement direction of the two first pressure rollers 310. The two first pressure rollers 310 are rotated and passed through the first mounting block 330 and the second mounting block 350 respectively. The machine base 100 is symmetrically arranged with first hydraulic cylinders 370 corresponding to the first mounting grooves 101. The first hydraulic cylinders 370 are connected and drive the first pressure rod 360 to move toward one side of the first length column 320 to drive the second mounting block 350, the second length column 340, the first mounting block 330 and the first length column 320 to press and fit in sequence. This solves the technical problem of the upper first pressing roller 310 being subjected to excessive upward displacement during the rolling process, resulting in poor rolling arching. A second length column 340, provided between the first mounting block 330 and the second mounting block 350, serves as a rigid connector, ensuring that the distance between the upper first pressing roller 310 and the lower second pressing roller 410 remains stable when pressure is applied by the first hydraulic cylinder 370. This avoids the uneven curvature caused by variations in the roller spacing in conventional equipment. Furthermore, after the first hydraulic cylinder 370 is driven into position, it can be coupled with a screw and nut locking mechanism to further secure the spacing between the first mounting block 330 and the second mounting block 350 after reaching the set pressure, thereby securing the spacing between the two first pressing rollers 310. This ensures consistent curvature during long-term processing, effectively improving product consistency and yield. Similarly, symmetrically arranged second mounting grooves 102 are provided on both sides of the machine base 100. The second mounting grooves 102 are provided with a first rigid column, a first connecting block 430, a second rigid column, a second connecting block 450 and a second pressure rod 460 which are overlapped in sequence in the arrangement direction of the two second pressure rollers 410. The two second pressure rollers 410 are rotated and passed through the first connecting block 430 and the second connecting block 450 respectively. The machine base 100 is symmetrically arranged with second hydraulic cylinders 470 corresponding to the second mounting grooves 102. The second hydraulic cylinder 470 is connected to and drives the second pressure rod 460 to move toward one side of the first rigid column to drive the second connecting block 450, the second rigid column, the first connecting block 430 and the first rigid column to press and fit in sequence. In this regard, the technical problem that the second pressing roller 410 on one side of the second rolling assembly 400 may deviate too much when subjected to force, resulting in poor rolling arching effect, is effectively solved. It can be understood that the second rigid column arranged between the first connecting block 430 and the second connecting block 450 serves as a key supporting component to ensure that the two second pressing rollers 410 can still maintain a stable relative position relationship when arranged obliquely upward, thereby avoiding the uncontrollable rolling effect of the metal plate 500 caused by the deviation of the second pressing roller 410 in traditional equipment.At the same time, after the second hydraulic cylinder 470 is driven into position, it can cooperate with the screw and nut locking mechanism to further fix the distance between the first connecting block 430 and the second connecting block 450 after reaching the set pressure, thereby fixing the distance between the two second pressing rollers 410, ensuring the consistency of the arc forming during the long-term processing process, and effectively improving the consistency and qualified rate of the product. It is easy to understand that the machine base 100 is provided with a drive component, which connects and drives the first pressing roller 310 and the second pressing roller 410 to move together. For example, the drive component includes a drive motor, a gear set and a synchronous wheel and synchronous belt structure that are sequentially connected in transmission. The ends of the first pressing roller 310 and the second pressing roller 410 are respectively rotated under the drive of the synchronous belt.

[0032] In some embodiments of the present invention, Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the feed assembly 200 includes a plurality of horizontally arranged feed rollers 210 and a plurality of vertically arranged limiting rollers 220. The plurality of feed rollers 210 are arranged horizontally and spaced apart to allow the metal sheet 500 to slide into the first arching channel 301. The plurality of limiting rollers 220 are arranged in an array on both sides of the feed rollers 210 to limit the position of the metal sheet 500 on both sides. To this end, the horizontally arranged feed rollers 210 reduce the frictional resistance between the metal sheet 500 and the feeding material, making the feeding operation more labor-saving and smooth. The two-sided constraint formed by the vertically arranged limiting rollers 220 effectively prevents the metal sheet 500 from swinging left and right during the feeding process, ensuring the stability of the feeding posture from the source and laying the foundation for high-quality forming. It is easy to understand that the spacing between the feed rollers 210 and the spacing between the limit rollers 220 can be adaptively adjusted according to the length and width of the metal plate 500, which improves the versatility of the equipment and is compatible with the processing requirements of metal plates 500 of different specifications, significantly improving the utilization rate and production flexibility of the equipment, and is particularly suitable for the production mode of metal plates 500 of multiple varieties and small batches. Figure 3 and Figure 5In some embodiments of the present invention, the feed assembly 200 includes a support block 2311, which is located between the feed roller 210 and the first arch channel 301. The support block 2311 has a contoured groove 23111 that matches the shape of the bottom surface of the metal plate 500, such as a contoured groove 23111 that is an arc-shaped structure that matches the shape of the concave arc portion 510. In addition, the support block 2311 is arranged to float in the vertical direction to float and support the end of the metal plate 500 to enter the first arch channel 301. It can not only meet the adaptive support requirements of metal plates 500 of different thicknesses, but also provide uniform support force when the metal plate 500 enters the first arch channel 301, solving the technical problem that traditional rigid support platforms easily cause the metal plate 500 to be partially suspended and unevenly stressed. Especially for the special-shaped metal plates 500 with curved surface transitions at the ends, the floating support design can significantly reduce the risk of deformation of the ends and improve the forming quality in the feeding stage. At the same time, the floating characteristics of the support block 2311 can also absorb the slight vibrations generated when the metal plate 500 is fed, avoiding the curvature deviation caused by vibration transmission, and further improving the consistency of the product. In addition, the floating support structure can also reduce the friction damage between the metal plate 500 and the supporting surface, extend the service life of the mold, and reduce production costs. For example, the machine base 100 is equipped with a spring cylinder 230, and the spring cylinder 230 is floatingly provided with a spring rod 231, and the support block 2311 is fixedly installed on the top of the spring rod 231. Optionally, there are two spring cylinders 230 and two support blocks 2311, and the two spring cylinders 230 are arranged at intervals in the axial direction of the feed roller 210, and the support blocks 2311 are arranged one by one with the spring cylinder 230 to support the two sides of the metal plate 500 respectively. Further, referring to Figure 5In some embodiments of the present invention, the support block 2311 is provided with a guide bevel 23112 and a support bevel 23113. One end of the guide bevel 23112 is connected to the contour groove 23111, and the other end is inclined downward toward one side of the feed roller 210. The support bevel 23113 is connected to the contour groove 23111 at one end, and the other end is inclined downward toward one side of the first arching channel 301. It should be noted that the guide bevel 23112 smoothly guides the metal sheet 500 from the feed roller 210 to the contour groove 23111, while the support bevel 23113 ensures that the end of the metal sheet 500 enters the first arching channel 301 at an optimal angle. This dual-bevel design solves the transition problem of the metal sheet 500 from horizontal feeding to inclined rolling, avoiding material tearing or wrinkling caused by sudden angle changes. It is particularly suitable for lightweight processing of thin metal sheets 500 and significantly reduces scrap rates during the feeding stage. In addition, the inclination angle of the inclined surface can be optimized and calculated, which can gradually increase the contact pressure in the process of guiding the metal plate 500, avoiding the problem of surface depression of the metal plate 500 caused by instantaneous excessive pressure in traditional equipment, and further improving the smoothness of the feeding process and the forming quality. In addition, this progressive guiding structure can also reduce the impact force of the metal plate 500 when entering the arch channel, reduce the operating noise of the equipment, and improve the working environment.

[0033] Refer again Figure 6 The method of use according to an embodiment of the present invention is applied to the metal plate processing and forming device according to an embodiment of the present invention; wherein the method of use comprises the following steps: S100, feeding; the metal plate 500 is placed horizontally on the feeding assembly 200, and then pushed into the first arch channel 301; S110, primary arching process: during feeding, the first rolling assembly 300 rolls the metal plate 500 to cause the metal plate 500 to bend upward; S120, secondary arching and returning material: During the primary arching process, the second rolling assembly 400 receives the metal plate 500 and rolls the metal plate 500 through the second rolling assembly 400 to drive the metal plate 500 to bend downward; S200 , material collection: After the secondary arching and material return, the processed metal plate 500 is manually collected on one side of the feeding component 200 .

[0034] According to the usage method of the embodiment of the present invention, by adopting the metal plate processing and forming device of the embodiment of the present invention, the metal plate 500 is subjected to two roll-forming and arching operations, and the return material function is organically integrated, thereby solving the problem of traditional loading and unloading shifting operations. Among them, the design of using the second rolling component 400 to directly transfer the metal plate 500 back to the feed side in the secondary arching and return material step eliminates the independent material receiving station and transfer equipment required by traditional equipment, which not only simplifies the operating process, but also achieves the optimal match between production rhythm and personnel allocation, significantly improving the overall production efficiency.
