Description

Technical Field

[0001] This utility model relates to the technical field of metal sheet processing equipment, and in particular to an arc pressing machine. Background Technology

[0002] In the manufacturing process of flower bed products, their main structure is usually assembled from multiple curved metal plates. These curved plates are generally processed using roll forming technology, where the metal sheet undergoes plastic deformation along a preset curved trajectory under the action of roll forming equipment, thereby forming a curved structure that meets the design requirements. However, in actual production, it has been found that due to the influence of factors such as the flow characteristics of the metal sheet, mold design parameters, and process control during roll forming, obvious wrinkling often occurs at the ends of the formed curved plates, especially in the middle area of ​​the curved surface. This wrinkling defect mainly manifests as irregular wrinkles or bulges on the surface of the metal sheet, and its formation mechanism is closely related to factors such as local stress concentration in the sheet during roll forming, uneven material flow, and insufficient matching between the mold radius and the sheet thickness.

[0003] However, such wrinkling defects directly affect the quality of subsequent splicing and assembly: on the one hand, the unevenness of the end surface caused by wrinkling prevents the curved panels from fitting tightly during splicing, resulting in visible gaps at the joints and reducing the product's sealing performance and overall aesthetics; on the other hand, dimensional deviations caused by wrinkling lead to a decrease in the fitting precision between the curved panels, affecting the stability of the flower bed structure and the consistency of its appearance after installation. Therefore, there is an urgent need for a dedicated mechanized shaping device that can efficiently and accurately correct the ends of the rolled curved panels to eliminate wrinkling defects and ensure the quality stability of subsequent splicing and assembly.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0022] In the manufacturing process of flower bed products, their main structure is typically assembled from multiple curved metal plates. These curved plates are generally processed using a roll forming process, where the metal sheet undergoes plastic deformation along a pre-set curved trajectory under the action of a roll forming device, thereby forming a curved structure that meets the design requirements. However, in actual production, it has been found that due to the influence of factors such as the flow characteristics of the metal sheet, mold design parameters, and process control during the roll forming process, such as... Figure 2 As shown, obvious wrinkling often occurs at the ends of the formed curved plate, especially in the middle area of ​​the curved surface. This wrinkling defect mainly manifests as irregular wrinkles or bulges on the surface of the metal sheet. Its formation mechanism is closely related to factors such as local stress concentration of the sheet during rolling, uneven material flow, and insufficient matching between the die corner radius and the sheet thickness.

[0023] However, such wrinkling defects directly affect the quality of subsequent splicing and assembly: on the one hand, the unevenness of the end surface caused by wrinkling prevents the curved panels from fitting tightly during splicing, resulting in visible gaps at the joints and reducing the product's sealing performance and overall aesthetics; on the other hand, dimensional deviations caused by wrinkling lead to a decrease in the fitting precision between the curved panels, affecting the stability of the flower bed structure and the consistency of its appearance after installation. Therefore, there is an urgent need for a dedicated mechanized shaping device that can efficiently and accurately correct the ends of the rolled curved panels to eliminate wrinkling defects and ensure the quality stability of subsequent splicing and assembly.

[0024] Therefore, such as Figure 1As shown, the arc pressing machine proposed in this utility model includes a punch press 100 and a tooling table 200 disposed on the punch press 100. The punch press 100 is provided with a punching die 110 that can move in a vertical direction, and the punching die 110 is provided with a plurality of arc-shaped punching heads 111, which are arranged linearly at intervals. Further, the tooling table 200 is provided with a plurality of arc-shaped positioning blocks 210, which are arranged in a one-to-one correspondence with the arc-shaped punching heads 111. The plurality of arc-shaped positioning blocks 210 cooperate to position one side surface of the end of the flower bed arc plate 300. The arc-shaped punching heads 111 can move toward one side of the arc-shaped positioning blocks 210 to shape the two side surfaces of the end of the flower bed arc plate 300. It should be noted that by setting multiple linearly spaced arc-shaped punch heads 111 on the punch press 100 and cooperating with the corresponding arc-shaped positioning blocks 210 on the tooling table 200, the end surface of the flower bed arc plate 300 can be shaped, such as... Figure 3 As shown, it can effectively eliminate wrinkling defects in the middle of the arc surface caused by roll forming, ensure seamless splicing, accurate installation dimensions, and improve the overall aesthetics and assembly consistency.

[0025] In some embodiments of this utility model, the number of arc-shaped punch heads 111 and arc-shaped positioning blocks 210 is A, and the number of arc-shaped portions 310 of the flower bed arc plate 300 is B, satisfying: 0.5*B≤A≤B. This ensures that the shaping device can cover a sufficient number of arc-shaped portions 310 for effective shaping, avoiding shaping blind spots caused by too few punch heads and preventing equipment redundancy and increased costs caused by too many punch heads. Thus, while ensuring the shaping effect, the structural design is optimized and balanced. For example, if the number of arc-shaped punch heads 111 and arc-shaped positioning blocks 210 is 4, and the number of arc-shaped portions 310 of the flower bed arc plate 300 is 7, the shaping of all arc-shaped portions 310 of the flower bed arc plate 300 can be completed in two punching shaping operations. Referring again... Figure 1In some embodiments of this utility model, both the stamping die 110 and the tooling table 200 are elongated, which can adapt to the shaping requirements of a wider flower bed arc plate 300, thus improving processing efficiency. Specifically, in some embodiments of this utility model, multiple arc-shaped stamping heads 111 are arranged at intervals along the length direction of the stamping die 110. This linear arrangement ensures that the arc-shaped stamping heads 111 can evenly cover multiple arc-shaped portions 310 of the arc plate, making the force on each part balanced and avoiding the problems of local over-shaping or under-shaping, thereby ensuring the shaping consistency and accuracy of the entire arc plate end. Correspondingly, in some embodiments of this utility model, multiple arc-shaped positioning blocks 210 are arranged at intervals along the length direction of the tooling table 200, corresponding to the linear arrangement of the arc-shaped stamping heads 111, forming a precise one-to-one correspondence. This ensures that each arc-shaped positioning block 210 can accurately support the corresponding arc-shaped portion 310 of the flower bed arc plate 300, preventing plate displacement or uneven deformation during the shaping process, and improving the stability and reliability of the shaping process.

[0026] In some embodiments of this utility model, the bottom surface of the arc-shaped punch head 111 is an arc surface, and the central angle corresponding to the arc surface is C, which satisfies: C≤60°, ensuring that the contact area between the arc-shaped punch head 111 and the arc-shaped part 310 is moderate, which not only ensures sufficient forming pressure and effect, but also avoids excessive deformation or stress concentration caused by excessive contact area, thus achieving an optimized match between forming force and sheet metal bearing capacity.

[0027] Refer to Figure 4 A flower bed 400 is formed by two curved flower bed panels 300 enclosing each other. Some of the curved flower bed panels 300 are straight strips, while others are arc-shaped. When shaping the arc-shaped portion 310 at the end of the arc-shaped flower bed panel 300, the length of the arc-shaped positioning block 210 for alignment and support is not suitable to be too long. If it is too long, the arc-shaped portion 310 at the end of the flower bed panel 300 will not fit well with the arc-shaped positioning block 210, and the arc-shaped positioning block 210 will not provide balanced support to the end of the flower bed panel 300. At the same time, an excessively short arc-shaped positioning block 210 is also not conducive to supporting the arc-shaped portion 310 at the end of the flower bed panel 300. Taking all factors into consideration, in some embodiments of this utility model, the length D of the arc-shaped positioning block 210 satisfies: 30mm ≤ D ≤ 100mm. This design ensures that the positioning block has an appropriate contact length to stably support the curved portion 310, preventing the sheet metal from wobbling or shifting during the forming process, while also avoiding situations where the support is not properly fitted due to excessive length. Furthermore, the equal lengths of the curved punch head 111 and the curved positioning block 210 ensure that the contact areas of the curved punch head 111 and the curved positioning block 210 are perfectly matched during the forming process. This avoids problems such as ineffective forming or over-forming of certain areas due to inconsistent lengths, thus improving the uniformity and consistency of the forming effect.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
