Description

Technical Field

[0001] This invention relates to the field of metal sheet processing and manufacturing technology, and in particular to a metal sheet roll forming apparatus and a method of using the metal sheet roll forming apparatus. Background Technology

[0002] In the manufacturing process of garden facilities such as flower beds, landscape decorative components, and some architectural decorative structures, it is often necessary to process sheet metal into curved plates with specific curvatures to meet requirements such as structural strength, load-bearing stability, or aesthetic decoration. Current technologies using general-purpose sheet metal bending and forming equipment mostly optimize only the feeding end, neglecting the output end, resulting in poor stability and convenience in product output. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a metal sheet roll forming device, which has the advantages of simple and safe operation, high forming accuracy, and convenient material collection.

[0006] Base;

[0007] A feeding assembly is disposed on the machine base, and the feeding assembly is used to horizontally support the metal plate;

[0008] A first roller pressing assembly is connected to the machine base and located on the output side of the feeding assembly. The first roller pressing assembly includes two vertically spaced first pressure rollers. The two first pressure rollers are radially opposed to form a first arching channel to bend upward after the metal plate passes through.

[0009] A discharge guide assembly is disposed on the machine base and located on the output side of the first roller pressing assembly. The discharge guide assembly includes a first guide wheel, which is located on the upper side of the first arching channel and rolls against the surface of the metal plate to discharge the metal plate.

[0010] The metal sheet roll forming apparatus according to the present invention has at least the following beneficial effects: the first arching channel formed by two vertically spaced first pressure rollers can stably extrude and deform the metal sheet, and efficiently process the metal sheet into an arch; in addition, the first guide wheel in the discharge guide assembly, located on the upper side of the first arching channel and rolling against the surface of the metal sheet, can reduce friction damage and ensure stable discharge of the metal sheet, thereby improving the overall processing quality and efficiency.

[0011] According to some embodiments of the present invention, the metal sheet roll forming apparatus further includes a second roll forming assembly connected to the base. The second roll forming assembly is located on the bending path of the metal sheet by the first roll forming assembly. The second roll forming assembly includes two second pressure rollers arranged obliquely upwards at intervals. The radially opposite sides of the two second pressure rollers form a second arching channel to bend downwards after the metal sheet passes through and to transport the metal sheet back to one side of the feeding assembly for unloading the processed metal sheet.

[0012] According to some embodiments of the present invention, the metal sheet roll forming apparatus has two first guide wheels, which are located between the first roll forming assembly and the second roll forming assembly. The two first guide wheels are arranged at intervals on the bending path of the metal sheet, and the two first guide wheels respectively abut against and guide the two side surfaces of the metal sheet.

[0013] According to some embodiments of the present invention, the metal plate roll forming apparatus includes a plurality of concave arc portions and a plurality of convex arc portions, the concave arc portions and the convex arc portions are arranged alternately in sequence, and two first guide wheels are staggered and respectively abut against the two sides of the same concave arc portion to limit the offset of the metal plate in the width direction.

[0014] According to some embodiments of the present invention, the metal sheet roll forming apparatus further includes two second guide wheels on the machine base. The two second guide wheels are located on the output side of the second roll forming assembly. The two second guide wheels are arranged at intervals on the bending path of the metal sheet, and the two second guide wheels respectively abut against and guide the two side surfaces of the metal sheet.

[0015] According to some embodiments of the present invention, the metal sheet roll forming apparatus has symmetrically arranged first mounting grooves on both sides of the machine base. In the arrangement direction of the two first pressure rollers, the first mounting grooves are provided with a first length column, a first mounting block, a second length column, a second mounting block, and a first pressure rod that overlap sequentially. The two first pressure rollers are respectively rotatably inserted through the first mounting block and the second mounting block. The machine base is symmetrically arranged with first hydraulic cylinders corresponding one-to-one with the first mounting grooves. The first hydraulic cylinders are connected to and drive the first pressure rods to move towards one side of the first length column, thereby driving the second mounting block, the second length column, the first mounting block, and the first length column to sequentially press against each other.

[0016] According to some embodiments of the present invention, the metal sheet roll forming apparatus includes a plurality of horizontally arranged feed rollers and a plurality of vertically arranged limiting rollers. The plurality of feed rollers are arranged at horizontal intervals to allow the metal sheet to slide into the first arching channel. The plurality of limiting rollers are arranged in an array on both sides of the feed rollers to limit the movement of the metal sheet on both sides.

[0017] According to some embodiments of the present invention, the metal sheet roll forming apparatus includes a feeding assembly comprising a support block located between the feeding roller and the first arching channel. The support block has a contour groove matching the shape of the bottom surface of the metal sheet. The support block is floatingly disposed in the vertical direction to floatly support the end of the metal sheet entering the first arching channel.

[0018] According to some embodiments of the present invention, the metal sheet roll forming apparatus has a support block provided with a guide slope and a support slope. One end of the guide slope is connected to the contour groove, and the other end is inclined downward toward one side of the feed roller. One end of the support slope is connected to the contour groove, and the other end is inclined downward toward one side of the first arching channel.

[0019] The method of using the metal sheet roll forming apparatus as described in this invention includes the following steps:

[0020] Feeding; the metal plate is placed horizontally on the feeding assembly and then pushed into the first arching channel;

[0021] One-time arching process: During feeding, the first roller pressing assembly rolls the metal plate, driving the metal plate to bend upward;

[0022] Secondary arching and material return: During the primary arching process, the second roller pressing assembly receives the metal plate and rolls the metal plate, driving the metal plate to bend downwards;

[0023] Material collection: After the secondary arching and material return, the processed metal plate is manually collected from one side of the feeding assembly.

[0024] According to the method of use described in this invention, it has at least the following beneficial effects: the metal sheet is formed by two roll forming and the return material function is organically integrated, which solves the problem of traditional feeding and unloading shifting operations. In particular, the design of using the second roll forming assembly to directly transfer the metal sheet back to the feeding side in the second roll forming and return material step eliminates the need for the independent receiving station and transfer equipment required by traditional equipment. This not only simplifies the operation process, but also optimizes the production cycle and personnel configuration, and significantly improves the overall production efficiency.

[0039] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] In the description of this invention, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the invention.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0044] In the manufacturing process of garden facilities such as flower beds, landscape decorative components, and some architectural decorative structures, it is often necessary to process sheet metal into curved plates with specific curvatures to meet requirements such as structural strength, load-bearing stability, or aesthetic decoration. Current technologies using general-purpose sheet metal bending and forming equipment mostly optimize only the feeding end, neglecting the output end, resulting in poor stability and convenience in product output.

[0045] Therefore, such as Figure 1 The diagram shows a metal sheet roll forming apparatus proposed in this invention, comprising a base 100, a feeding assembly 200 disposed on the base 100, a first roll forming assembly 300 connected to the base 100 and located on the output side of the feeding assembly 200, and a discharge guide assembly disposed on the base 100 and located on the output side of the first roll forming assembly 300. The feeding assembly 200 horizontally supports the metal sheet 500. The first roll forming assembly 300 includes two vertically spaced first pressure rollers 310, whose radial orientation forms a first arching channel 301, allowing the metal sheet 500 to bend upwards after passing through. Further, the discharge guide assembly includes a first guide wheel 110, located above the first arching channel 301 and rollingly engaging with the surface of the metal sheet 500 to guide the metal sheet 500 outwards. 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, efficiently processing the metal plate 500 into an arch; in addition, the first guide wheel 110 in the discharge guide assembly, located on the upper side of the first arching channel 301 and rolling against the surface of the metal plate 500, can reduce friction damage and ensure the stable discharge of the metal plate 500, thereby improving the overall processing quality and efficiency.

[0046] For example, metal sheets, such as flower bed tiles, are key splicing components in the structure of flower beds. Their curved design not only affects the overall aesthetics of the flower bed but also directly relates to drainage performance, structural stability, and service life, making them a core component in horticultural product manufacturing. Currently, flower bed products are increasingly developing towards miniaturization and refinement, placing higher demands on the curvature of flower bed tiles. However, existing technology for arching flower bed tiles mainly relies on a single-pass rolling process, which applies unidirectional pressure to the flower bed tile using a pair of fixed-distance rollers, forcing it to form a single-direction curved structure. This traditional process has significant limitations: firstly, the curvature achievable with a single pass is limited, making it difficult to meet the processing requirements for large-curvature bends, especially unsuitable for smaller flower bed components requiring higher curvature. Secondly, because smaller flower beds have more precise curvature requirements for the flower bed tiles, traditional equipment cannot achieve sufficient curvature changes in a single forming process, resulting in products that fail to meet design requirements and affecting the overall aesthetics and structural stability of the flower bed. On the other hand, the traditional operating method requires operators to manually place the flower bed tiles to be processed on the input side of the pressure roller, and then manually retrieve the finished flower bed tiles from the other side after processing. This requires operators to move between positions to collect the materials, resulting in high labor intensity and low efficiency in material collection. To address this, in some embodiments of the present invention, such as... Figures 2 to 5As shown, the machine base 100 is also connected to a second roller pressing assembly 400. The second roller pressing assembly 400 is located on the bending path of the first roller pressing assembly 300 on the metal plate 500. The second roller pressing assembly 400 includes two second pressure rollers 410 arranged obliquely upward. The radially opposite sides of the two second pressure rollers 410 form a second arching channel 401 to bend downward after the metal plate 500 passes through and to transport the metal plate 500 back to one side of the feeding assembly 200 for unloading the processed metal plate 500. It should be noted that by setting up a systematic structure of machine base 100, feeding assembly 200, first roller pressing assembly 300 and second roller pressing assembly 400, the integrated function of efficient and precise arching forming of metal plate 500 and convenient material collection is realized. This effectively solves the two major technical problems of insufficient curvature and inconvenient material collection in the existing single roller pressing process. In particular, by integrating the synergistic effect of the first roller pressing assembly 300 and the second roller pressing assembly 400, efficient and precise two-stage arching forming of metal plate 500, such as flower bed tile, is realized. It is particularly suitable for processing long metal plates 500. On the one hand, it solves the technical bottleneck of insufficient curvature in the traditional single roller pressing process, especially suitable for the production needs of small-shaped flower bed assembly parts that require higher curvature. On the other hand, through the circulating conveying path of metal plate 500 inside the device, the cumbersome operation of placing and collecting metal plate 500 on the input side of the pressure roller is eliminated, which significantly reduces labor intensity and improves material collection efficiency, making the production process more continuous and efficient.

[0047] In some embodiments of the present invention, reference is made to... Figures 2 to 4 The machine base 100 is equipped with two first guide wheels 110, located between the first roll forming assembly 300 and the second roll forming assembly 400. The two first guide wheels 110 are spaced apart along the bending path of the metal plate 500, and respectively abut against the two side surfaces of the metal plate 500 for guidance. On one hand, this guiding structure prevents lateral swaying caused by vibration or material elasticity during high-speed passage, thus ensuring the accuracy of upward arc forming and avoiding asymmetric or superimposed deformation due to offset, significantly improving the quality and consistency of bidirectional arch forming. On the other hand, the guiding design of the two first guide wheels 110 effectively solves the technical problem of easy offset of the metal plate 500 due to lack of lateral constraint during the transition from upward bending of the first arching channel 301 to downward bending of the second arching channel 401, ensuring the path stability of the metal plate 500 during the transition, especially for metal plates 500 with smaller widths. (Refer to...) Figure 4In some embodiments of the present invention, the metal plate 500 includes a plurality of concave arc portions 510 and a plurality of convex arc portions 520, which are arranged alternately in sequence. Two first guide wheels 110 are staggered and respectively abut against the two sides of the same concave arc portion 510 to limit the offset of the metal plate 500 in the width direction. Furthermore, by making full use of the alternating concave and convex geometric features of the surface of the metal plate 500, the asymmetrical distribution of contact points achieves precise limitation of the width direction displacement of the metal plate 500. Compared with the traditional symmetrical guiding method, it is more adaptable to the needs of local curvature changes of the metal plate 500, and can also effectively prevent the torsional deformation of small metal plates 500 due to insufficient rigidity during bidirectional rolling. Meanwhile, the staggered arrangement increases the guide channel between the two first guide wheels 110 for the metal plate 500 to enter. For example, even if the metal plate 500 is slightly deflected, it can still enter between the two first guide wheels 110. This allows the metal plate 500 to pass better between the two first guide wheels 110, while avoiding surface indentation damage caused by excessive extrusion. It improves the surface quality and forming smoothness of the metal plate 500 while ensuring guiding accuracy, making it particularly suitable for the production of garden metal plates 500 with high precision requirements.

[0048] Similarly, in some embodiments of the present invention, reference is made to... Figures 2 to 4 The base 100 is equipped with two second guide wheels 120. The two second guide wheels 120 are located on the output side of the second roller pressing assembly 400. The two second guide wheels 120 are arranged at intervals on the bending path of the metal plate 500. The two second guide wheels 120 respectively abut against the two side surfaces of the metal plate 500 for guidance. Thus, a closed-loop guiding system is formed for the entire process from bending to material collection. This effectively solves the technical difficulty that the metal plate 500 is prone to deviating from the preset path and returning after bending and springing back due to inertial impact and gravity. It ensures 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. This not only significantly reduces the labor intensity of operators, but also reduces the risk of product collision damage by reducing human intervention. At the same time, the tilt angle of the second guide wheels 120 can be optimized to provide progressive support force during the springback stage of the metal plate 500, preventing arc rebound or shape distortion caused by excessive springback speed, and further improving the dimensional stability and surface flatness of the final product. Optionally, similar to the 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 offset of the metal plate 500 in the width direction.

[0049] In some embodiments of the present invention, such as Figure 2 and Figure 3As shown, the machine base 100 has symmetrically arranged first mounting grooves 101 on both sides. The first mounting grooves 101 have 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 that are sequentially overlapped in the arrangement direction of the two first pressure rollers 310. The two first pressure rollers 310 are respectively rotatably inserted through the first mounting block 330 and the second mounting block 350. The machine base 100 has symmetrically arranged first hydraulic cylinders 370 that correspond one-to-one with the first mounting grooves 101. The first hydraulic cylinders 370 are connected to and drive the first pressure rod 360 to move toward one side of the first length column 320, so as 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 against each other in sequence. To address this issue, a second length column 340 is installed between the first mounting block 330 and the second mounting block 350 as a rigid connector. This ensures that the distance between the first mounting block 310 and the second mounting block 410 remains stable when the first hydraulic cylinder 370 applies pressure, avoiding the uneven curvature caused by changes in the roller spacing in traditional equipment. Furthermore, after the first hydraulic cylinder 370 is driven into position, a screw and nut locking mechanism can be used to further fix the distance between the first mounting block 330 and the second mounting block 350 after the set pressure is reached. This, in turn, fixes the distance between the two first mounting blocks 310, ensuring consistent curvature formation during long-term processing and effectively improving product consistency and yield. Similarly, the base 100 has symmetrically arranged second mounting grooves 102 on both sides. The second mounting grooves 102 have a first rigid column, a first connecting block 430, a second rigid column, a second connecting block 450 and a second pressure rod 460 that are sequentially overlapped in the arrangement direction of the two second pressure rollers 410. The two second pressure rollers 410 are respectively rotatably inserted through the first connecting block 430 and the second connecting block 450. The base 100 has symmetrically arranged second hydraulic cylinders 470 that correspond one-to-one with the second mounting grooves 102. The second hydraulic cylinders 470 are connected to and drive the second pressure rod 460 to move toward one side of the first rigid column, so as to drive the second connecting block 450, the second rigid column, the first connecting block 430 and the first rigid column to press against each other in sequence. This effectively solves the technical problem that the second pressure roller 410 on one side of the second roller pressing assembly 400 may deviate too much when subjected to force, resulting in poor roller pressing arching effect. It is understood that the second rigid column set between the first connecting block 430 and the second connecting block 450 serves as a key support component, ensuring that the two second pressure rollers 410 can maintain a stable relative position relationship even when arranged obliquely upward, thus avoiding the uncontrollable rolling effect of the metal plate 500 caused by the deviation of the second pressure roller 410 in traditional equipment.Simultaneously, 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 pressure rollers 410. This ensures the consistency of arc forming during long-term processing and effectively improves product consistency and pass rate. It is easy to understand that the machine base 100 is equipped with a drive assembly that connects to and drives the first pressure roller 310 and the second pressure roller 410 to move together. For example, the drive assembly includes a drive motor, a gear set, and a synchronous pulley and synchronous belt structure connected in sequence. The ends of the first pressure roller 310 and the second pressure roller 410 rotate under the drive of the synchronous belt.

[0050] In some embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the feeding assembly 200 includes multiple horizontally arranged feeding rollers 210 and multiple vertically arranged limiting rollers 220. The feeding rollers 210 are arranged horizontally at intervals to allow the metal plate 500 to slide into the first arching channel 301. The limiting rollers 220 are arranged in an array on both sides of the feeding rollers 210 to limit the movement of the metal plate 500 on both sides. In this way, the horizontally arranged feeding rollers 210 reduce the frictional resistance between the metal plate 500 and the material during feeding, making the pushing operation more effortless and smooth. The double-sided constraint formed by the vertically arranged limiting rollers 220 effectively prevents the metal plate 500 from swaying left and right during feeding, ensuring the stability of the feeding posture from the source and laying the foundation for high-quality molding. 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 sheet 500, improving the versatility of the equipment and enabling it to meet the processing needs of metal sheets 500 of different specifications. This significantly improves the utilization rate and production flexibility of the equipment, making it particularly suitable for multi-variety, small-batch metal sheet 500 production. (Refer to...) Figure 3 and Figure 5In some embodiments of the present invention, the feeding assembly 200 includes a support block 2311 located between the feeding roller 210 and the first arching 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 an arc-shaped structure that matches the shape of the concave arc portion 510. Furthermore, the support block 2311 is vertically floating to support the end of the metal plate 500 as it enters the first arching channel 301. This design adapts to the needs of metal plates 500 of varying thicknesses and provides uniform support when the metal plate 500 enters the first arching channel 301, solving the technical problem of uneven stress and partial suspension of the metal plate 500 caused by traditional rigid support platforms. Especially for irregularly shaped metal plates 500 with curved transitions at the ends, the floating support design can significantly reduce the risk of end deformation and improve the forming quality during the feeding stage. Simultaneously, the floating characteristic of the support block 2311 can absorb the slight vibrations generated during the feeding of the metal plate 500, avoiding curvature deviations caused by vibration transmission, further improving product consistency. Furthermore, the floating support structure can reduce frictional damage between the metal plate 500 and the support surface, extending mold life and reducing production costs. For example, the machine base 100 is equipped with a spring cylinder 230, with a floating spring rod 231 mounted on the spring cylinder 230, and the support block 2311 is fixedly mounted on the top of the spring rod 231. Optionally, there are two spring cylinders 230 and two support blocks 2311. The two spring cylinders 230 are spaced apart axially on the feed roller 210, and the support blocks 2311 are arranged corresponding to the spring cylinders 230 to support both 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 slope 23112 and a support slope 23113. One end of the guide slope 23112 is connected to the contour groove 23111, and the other end is inclined downward toward one side of the feed roller 210. One end of the support slope 23113 is connected to the contour groove 23111, and the other end is inclined downward toward one side of the first arching channel 301. It should be noted that the guide slope 23112 smoothly guides the metal plate 500 from the feed roller 210 to the contour groove 23111, while the support slope 23113 ensures that the end of the metal plate 500 enters the first arching channel 301 at the optimal angle. This dual-slope collaborative design solves the transition problem of the metal plate 500 from horizontal feeding to inclined roller pressing, avoiding material tearing or wrinkling caused by sudden angle changes. It is especially suitable for the lightweight processing requirements of thin metal plates 500 and significantly reduces the scrap rate in the feeding stage. In addition, the inclination angle of the ramp can be optimized and calculated to gradually increase the contact pressure during the process of guiding the metal plate 500, avoiding the problem of surface depression of the metal plate 500 caused by excessive instantaneous pressure in traditional equipment, further improving the stability of the feeding process and the forming quality. Furthermore, this progressive guiding structure can also reduce the impact force when the metal plate 500 enters the arching channel, reduce equipment operating noise, and improve the working environment.

[0051] Refer to Figure 6 The method of use according to an embodiment of the present invention is applied to a metal sheet roll forming apparatus according to an embodiment of the present invention; wherein, the method of use includes the following steps:

[0052] S100, Feeding; Metal plate 500 is placed horizontally on feeding assembly 200 and then pushed into first arching channel 301;

[0053] S110, One-time arching process: During feeding, the first roller pressing assembly 300 presses the metal plate 500, driving the metal plate 500 to bend upward;

[0054] S120, Secondary arching and material return: During the primary arching process, the second roller pressing assembly 400 receives the metal plate 500 and rolls the metal plate 500 through the second roller pressing assembly 400, driving the metal plate 500 to bend downward.

[0055] S200, Material Retrieval: After the secondary arching and material return, the processed metal plate 500 is retrieved manually from one side of the feeding assembly 200.

[0056] According to the usage method of this embodiment, the metal plate roll forming device of this embodiment performs two roll forming processes to arch the metal plate 500 and organically integrates the return material function, solving the problems of traditional feeding and unloading shifting operations. In particular, the design of using the second roll forming component 400 to directly transfer the metal plate 500 back to the feeding side in the second arching return material step eliminates the need for the independent receiving station and transfer equipment required by traditional equipment. This not only simplifies the operation process but also optimizes the production cycle and personnel configuration, significantly improving the overall production efficiency.
