Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a fully automated arc integral forming and bending processing center. Background Technology

[0002] In traditional furniture manufacturing processes, achieving rounded edges on boards mainly involves splicing, which involves cutting the board into multiple small pieces and then combining them into a rounded shape through sanding, splicing, and gluing. This non-integrated structure affects the product's strength and aesthetics, and also results in poor quality stability and a high scrap rate.

[0003] To solve the above-mentioned technical problems, those skilled in the art have proposed to cut grooves in the thickness direction of the area to be bent in the flat plate, and then apply bending force to the plate to make it bend along the preset gap, so as to finally form a smooth and continuous arc shape on the other side of the plate, thus realizing the integration of the arc structure and the plate body.

[0004] Currently, related processing operations in the market almost entirely rely on manual or semi-mechanized methods. Operators need to hold the sheet metal and align and process it using ordinary engraving machines, CNC milling machines, or simple grooving equipment. After grooving, it usually requires two or more workers to work together, manually bending the sheet metal to the required curvature using simple clamps or equipment such as simple presses, relying on experience and feel. To maintain the bent shape and increase structural strength, glue is usually injected into the grooving gap, and clamps are used to fix the bent sheet metal while waiting for the glue to cure. The existing technical problems are low efficiency, poor precision, difficulty in ensuring consistency, high skill requirements for workers, and the glue posing a health hazard.

Detailed Implementation

[0017] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] In modern furniture design, interior decoration, and high-end architectural decoration, panel components with rounded edges are widely used in pursuit of a smoother, more elegant, and more design-oriented visual effect. For example, the use of rounded edges on tabletops, cabinet door corners, bar counter sides, and wall panel finishes not only enhances the overall aesthetics and artistry of the product but also effectively avoids the safety hazards posed by sharp edges, increasing comfort and safety during use.

[0019] In traditional furniture manufacturing processes, achieving rounded edges on boards primarily relies on splicing and forming techniques. This typically involves cutting flat pieces of wood or boards into multiple small pieces, then sanding, splicing, and gluing them together manually or semi-manually to form a pre-defined rounded shape. This process presents the following technical challenges: The rounded edge formed by splicing is essentially composed of multiple independent components, resulting in poor overall structural integrity. Under prolonged use or uneven stress, stress concentration easily occurs at the joints, leading to cracking, deformation, or even damage, severely impacting the product's lifespan. Furthermore, the ever-present or tactile seams between components disrupt the continuity and integrity of the board's surface texture, affecting the overall quality and aesthetics of the final product. Traditional splicing processes require multiple complex steps, including marking, cutting, grinding, gluing, alignment, clamping, curing, and secondary finishing. Each step relies on manual operation and experience-based judgment by skilled workers, consuming significant manpower and time, and resulting in long production cycles, failing to meet the demands of modern large-scale, high-efficiency production.

[0020] Furthermore, due to the reliance on manual operation, the operational status of different workers, or even the same worker at different times, varies. This makes it difficult to maintain a high degree of consistency in the curvature, size, and smoothness of the assembled arc edges, resulting in inconsistent product quality and poor stability. In addition, the complex operation process increases the probability of errors, leading to a high scrap rate and further increasing production costs.

[0021] To overcome the drawbacks of traditional splicing processes, those skilled in the art have proposed integrated bending forming. This involves creating a partially penetrating slit of controllable depth and shape in the thickness direction of the area to be bent on a flat sheet. This slit disrupts the local rigidity of the sheet in that area, allowing the remaining portion to undergo plastic or elastic deformation under external force. Subsequently, a bending force is applied to the sheet, bending it along the pre-set slit, ultimately forming a smooth, continuous arc shape on the other side of the sheet, the ungrooved surface. This achieves integration of the arc structure with the sheet body, fundamentally solving the structural strength problem of splicing processes. The resulting product is seamless, with a complete and uniform appearance and excellent texture.

[0022] Currently, almost all related processing operations in the market rely entirely on manual or semi-mechanized methods. The entire process is manual, resulting in poor workflow coordination, slow production cycles, and an inability to achieve continuous, large-scale production. Furthermore, the randomness and cumulative errors of manual operation lead to variations in the curvature and dimensional accuracy of each product, resulting in highly inconsistent product quality that fails to meet the requirements of standardized production. In addition, the adhesives commonly used in the bonding process (such as urea-formaldehyde resin and phenolic resin) often contain volatile organic compounds (VOCs) such as formaldehyde, which evaporate into the air during operation, posing a threat to human health and polluting the production environment.

[0023] like Figure 1-9 As shown in some illustrative embodiments, a fully automated arc-shaped integral forming and bending machining center is provided, including: a sheet metal processing positioning ruler 100, an arc-shaped milling cutter device, an adhesive injection processing device 500, an arc-shaped bending processing device 600, and a cooling device 700.

[0024] The sheet metal processing positioning ruler 100 is set in the feeding area of ​​the bending machine operating table 800. It is used to adjust the processing width of the sheet metal. That is, before processing, the width of the sheet metal processing area is adjusted according to the required arc size of the sheet metal.

[0025] Specifically, the sheet metal processing positioning ruler 100 includes: a ruler base 110, a ruler pad 120, and a ruler 130. The ruler base 110 is set on the bending machine operating table 800. The ruler pad 120 is connected to the ruler base 110 through a guide rail 140. The ruler 130 is set on the ruler pad 120, so that the ruler 130 can move laterally along the bending machine operating table 800, thereby adjusting the width of the sheet metal processing area. It has the advantages of stable structure and easy adjustment.

[0026] An arc-shaped milling cutter device is installed on the discharge side of the sheet metal processing positioning ruler 100 and is used to cut grooves on the sheet metal. Further, the arc-shaped milling cutter device includes: a first milling cutter mechanism 200, installed on the discharge side of the sheet metal processing positioning ruler 100, used to pre-groove the area where grooving is required on the sheet metal to prevent edge bursting; a second milling cutter mechanism 300, installed on the discharge side of the first milling cutter mechanism 200, used to cut grooves on the sheet metal; and a dual-motor grooving mechanism 400, installed on the discharge side of the second milling cutter mechanism 300, used to groove the sheet metal.

[0027] The first milling cutter mechanism 200 includes: a first tool magazine 210, a first motor mounting base 220, a first base 230, and a first bracket 240. The tool base of the first tool magazine 210 is arranged laterally along the bending machine operating table 800 and is equipped with a linear guide rail, allowing the tool carrier of the first tool magazine 210 to move laterally. The first tool magazine 210 is equipped with four types of tools. During processing, the required type of tool is selected and installed on the tool motor 203, which is mounted on the first motor mounting base 220, for pre-processing of the sheet metal.

[0028] The first support 240 is connected to the bending machine operating table 800 via a Y-axis ball screw transmission mechanism 250, allowing the first support 240 to move along the longitudinal direction of the bending machine operating table 800, i.e., the direction of material movement. The first base 230 is connected to the first support 240 via an X-axis ball screw transmission mechanism 213, allowing the first base 230 to move along the transverse direction of the bending machine operating table 800, which is the direction perpendicular to the longitudinal direction of the bending machine operating table 800 in the horizontal plane. The first motor mounting base 220 is connected to the first base 230 via a Z-axis ball screw transmission mechanism 223, allowing the first motor mounting base 220 to move up and down along a direction perpendicular to the bending machine operating table 800. This structural design allows the cutter to move in the X, Y, and Z directions, thereby adjusting the cutter's position and pre-machining the correct required grooves on the material.

[0029] The second milling cutter mechanism 300 includes a second tool magazine 310, a second motor mounting base 320, a second base 330, and a second bracket 340. The second tool magazine 310 is also equipped with four types of cutting tools. During machining, the required type of tool is selected and mounted on the tool motor 203, which is mounted on the second motor mounting base 323. This allows for secondary machining of the sheet metal, ultimately forming the groove.

[0030] The second bracket 340 is mounted on the bending machine operating table 800. The second base 330 is connected to the second bracket 340 via an X-axis ball screw transmission mechanism 213, allowing the second base 330 to move laterally along the bending machine operating table 800. The second motor mounting base 320 is connected to the second base 330 via a Z-axis ball screw transmission mechanism 223, allowing the second motor mounting base 320 to move vertically along a direction perpendicular to the bending machine operating table 800. This structural design allows the cutter in the second milling cutter mechanism 300 to adjust its position to ultimately cut the correct groove on the sheet metal.

[0031] The dual-motor grooving mechanism 400 includes two parallel processing motors 410, with a circular blade at the drive end of each processing motor 410 to groove the sheet metal, allowing the sheet metal to be connected to other sheet metals.

[0032] The glue injection device 500 is located on the discharge side of the arc forming milling cutter device and is used to inject glue into the grooves processed and cut by the device. Specifically, the glue injection device 500 includes a glue gun 510 and a glue dispenser 520 that supplies glue to the glue gun 510. Both the glue gun 510 and the glue dispenser 520 are mounted on the bending machine operating table 800. The glue dispenser 520 contains glue, which is pumped into the glue gun 510 by a peristaltic pump. The glue gun 510 then injects the glue into the grooves processed by the arc forming milling cutter device.

[0033] An arc bending processing device 600 is installed on the discharge side of the glue injection processing device 500 and is used to bend the sheet material along the groove. Specifically, the arc bending processing device 600 includes: a C-shaped track 610, a drive motor 620, and a pressing mechanism 630. The drive motor 620 is mounted on the pressing mechanism 630. An arc-shaped rack 640 is installed on the C-shaped track 610. A gear 650 is installed on the power output shaft of the drive motor 620, meshing with the arc-shaped rack 640. When the drive motor 620 is working, it drives the gear 650 to rotate. As the gear 650 rotates, it moves along the arc-shaped rack 640, thereby causing the pressing mechanism 630 to rotate as a whole, performing a bending operation on the sheet material fixed on the pressing mechanism 630, and bending along the groove. A heating plate is also installed at the arc bending processing device 600 to prevent the glue from solidifying prematurely.

[0034] The pressing mechanism 630 includes several cylinders 660, which can press the sheet material when they extend.

[0035] A cooling device 700 is installed on the discharge side of the arc bending processing device 600 and is used to cool the sheet material. The cooling device 700 includes a compressor 710 and an air outlet pipe. The compressor 710 provides cold air, which is blown onto the sheet material through the air outlet pipe, thereby cooling the sheet material and the adhesive and setting it in shape.

[0036] This application integrates a panel processing positioning ruler 100, an arc forming milling cutter device, an adhesive injection processing device 500, an arc bending processing device 600, and a cooling device 700 on a bending machine operating table 800 in sequence, constructing a complete production line. From material feeding to final forming and cooling, the various devices achieve continuous operation, improving production efficiency, greatly shortening the production cycle, and meeting the large-scale, high-efficiency production needs of modern furniture manufacturing.

[0037] The sheet metal processing positioning ruler 100 ensures accurate grooving positions, the arc forming milling cutter device can cut grooves of consistent height at a constant depth and path, and the arc bending processing device 600 can perform sheet metal bending operations with preset force and angle. The entire process is standardized, effectively avoiding human processing errors caused by individual differences in manual operation, ensuring that the arc curvature and dimensional specifications of each finished product are consistent, thereby significantly improving the overall quality of the product.

[0038] Workers are only required to perform simple auxiliary tasks such as loading and unloading materials, greatly reducing labor intensity. More importantly, the glue injection processing device eliminates the need for workers to directly contact the glue during operation, avoiding the direct health hazards posed by volatile harmful substances in the glue. Furthermore, the equipment can be designed as a closed or semi-closed system, equipped with an exhaust system to effectively collect and treat the volatile gases from the glue, significantly improving the working environment in the production workshop.

[0039] This application directly manufactures arc structures on a single piece of board, replacing the cumbersome splicing, sanding, and gap-filling steps of traditional splicing processes, greatly simplifying the production process. Moreover, since the arc is formed by bending the board itself as a single piece, its structure is continuous and seamless, resulting in superior mechanical properties and structural strength far exceeding that of spliced ​​components, making it less prone to damage. Furthermore, the one-piece molded arc has a smooth surface and flowing lines, eliminating the need for additional gap-filling treatments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
