Description

Technical Field

[0001] This utility model relates to an aluminum honeycomb panel bending technology, and more particularly to an aluminum honeycomb panel right-angle bending structure. Background Technology

[0002] Aluminum honeycomb panels are widely used due to their strength being more than four times that of traditional wood panels, their eco-friendly nature (formaldehyde-free), impact resistance, ease of maintenance, water and insect resistance, and their ability to improve the environment inside homes and throughout rooms. Aluminum honeycomb panels typically refer to panels with thin aluminum sheets on the top and bottom surfaces, a honeycomb-shaped filling core in the middle, and edge banding on all four sides (see appendix). Figure 1 In the diagram, a is the top panel, b is the bottom panel, c is the filling core, and d is the edge sealing. If the honeycomb filling core is made of aluminum, this type of panel is called an all-aluminum honeycomb panel, which has advantages such as lighter weight, higher strength and rigidity, waterproof and insect-proof properties, and resistance to deformation.

[0003] As is well known, when making panel furniture using boards, it is common to fix and assemble two boards into an L-shape. The same L-shaped assembly (often called right-angle assembly) is used when making panel furniture using aluminum honeycomb panels. Existing technology for right-angle assembly of aluminum honeycomb panels borrows the assembly method from wood panel furniture. Specifically, a through hole is drilled on the side of aluminum honeycomb panel II to allow the bolt head to be inserted; a corresponding through hole is drilled on the surface of aluminum honeycomb panel II to accommodate a screw thread; the through hole and the screw thread are interconnected, their axes intersect, and they are on the same plane. A corresponding through hole is drilled on the surface of aluminum honeycomb panel I to allow the rivet nut to be inserted, and the rivet nut is riveted into this through hole. The bolt is screwed into the rivet nut, and then the bolt head is inserted into the through hole on the side of aluminum honeycomb panel II. The screw thread is then inserted into the screw hole on the surface of aluminum honeycomb panel II, and the screw thread is rotated with a screwdriver until the screw thread's slot engages with the bolt head. This completes the L-shaped assembly of aluminum honeycomb panel I and aluminum honeycomb panel II (see appendix). Figure 2 In the diagram, 1 represents aluminum honeycomb panel I, 1-1 is a rivet nut, and 1-2 is a bolt; 2 represents aluminum honeycomb panel II, 2-1 is a screw hole, 2-2 is a through hole, and 2-3 is a screw thread. This connection method, when used for right-angle assembly of wood panels, generally meets the requirements and ensures sufficient strength and rigidity of the assembled furniture. However, when used for assembling aluminum honeycomb panels, the thinness of the honeycomb core skeleton (usually only a fraction of a millimeter) is insufficient to withstand lateral forces; furthermore, the aluminum panel thickness is typically only about 0.8mm, which also cannot withstand significant external forces. This results in poor strength and rigidity of the right-angle structure after assembly, severely impacting the lifespan of the aluminum alloy furniture.

[0004] Clearly, the existing technology for assembling aluminum honeycomb panels at right angles has problems such as poor strength and rigidity of the assembled right-angle structure, which seriously affects the service life of aluminum alloy furniture. Summary of the Invention

[0005] To address the problems of poor strength and rigidity of the assembled right-angle structure in existing aluminum honeycomb panel assembly methods, which seriously affect the service life of aluminum alloy furniture, this utility model proposes a right-angle bending structure for aluminum honeycomb panels.

[0006] This utility model relates to a right-angle bending structure for an aluminum honeycomb panel. Using the bending line as a reference, a V-shaped notch with a 90-degree apex angle and symmetrical left and right sides is provided along the bending line on the aluminum honeycomb panel to be bent. A right-angle flange is provided on the right side of the V-shaped notch, formed by bending the upper panel upwards by 90 degrees with the edge of the V-shaped notch as a reference. The apex angle of the V-shaped notch extends 0.1-0.3 mm into the upper surface of the lower panel of the aluminum honeycomb panel to be bent, thus forming a bending groove I. When the left side of the V-shaped notch of the aluminum honeycomb panel to be bent is bent 90 degrees along the bending groove I to the right, the upper surface of the left side of the upper panel is in close contact with the left surface of the right-angle flange. The bending line refers to the outer apex angle line of the right angle formed after the aluminum honeycomb panel to be bent at a right angle; the edge of the V-shaped notch refers to the straight line formed by the intersection of the inclined surface of the V-shaped notch and the upper surface of the right side of the upper panel of the aluminum honeycomb panel to be bent.

[0007] Furthermore, the left side portion of the V-shaped notch has an adhesive or welded structure between the upper surface of the top plate and the left surface of the right-angle flange.

[0008] Furthermore, on the upper plate to the right of the V-shaped notch of the aluminum honeycomb panel to be bent, a groove with a depth of 0.1-0.3mm is set with the edge of the V-shaped notch as a reference, thus forming bending groove II, so as to facilitate the bending of the right-angle flange.

[0009] The beneficial technical effect of this utility model's aluminum honeycomb panel right-angle bending structure is that it replaces the right-angle assembly structure with a right-angle bending structure, fundamentally solving the problems of aluminum honeycomb panels being unable to withstand large lateral forces and having loose internal structure, ensuring the right-angle bending strength and rigidity, and guaranteeing the service life of aluminum alloy furniture.

[0017] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates the right-angle bending structure and bending method of the aluminum honeycomb panel of this utility model. Detailed Implementation

[0018] See appendix Figure 5 , 6 As shown in the figure, the right-angle bending structure of the aluminum honeycomb panel of this utility model has a V-shaped notch 3-2 with a 90-degree apex angle and symmetrical left and right sides, set along the bending line on the aluminum honeycomb panel to be bent. On the right side of the V-shaped notch, a right-angle flange 3-4 is formed by bending the upper panel upward by 90 degrees with the edge of the V-shaped notch as the reference. The apex angle of the V-shaped notch extends 0.1-0.3mm into the upper surface of the lower plate of the aluminum honeycomb panel to be bent, thereby forming a bending groove I 3-3. When the left side of the V-shaped notch of the aluminum honeycomb panel to be bent is bent 90 degrees along the bending groove I to the right side, the upper surface of the upper plate of the left side is in close contact with the left surface of the right-angle flange. The bending line refers to the outer apex angle line of the right angle formed after the aluminum honeycomb panel to be bent is bent at a right angle. The edge of the V-shaped notch refers to the straight line formed by the intersection of the inclined surface of the V-shaped notch and the upper surface of the right side of the upper plate of the aluminum honeycomb panel to be bent. This utility model's aluminum honeycomb panel right-angle bending structure replaces the L-shaped assembly structure, fundamentally solving the problems of aluminum honeycomb panels being unable to withstand large lateral forces and having loose internal structure, thus ensuring strength and rigidity and guaranteeing the service life of aluminum alloy furniture.

[0019] As one of the preferred technical solutions, the upper surface of the left side portion of the V-shaped notch and the left surface of the right-angle flange are bonded or welded together. After the upper surface of the left side portion of the V-shaped notch is bonded or welded to the right-angle flange, a stable support and connection structure is formed, effectively ensuring the strength and rigidity of the right-angle bending structure.

[0020] As one of the preferred technical solutions, a groove with a depth of 0.1-0.3mm is set on the upper plate on the right side of the V-shaped notch of the aluminum honeycomb panel to be bent, with the edge of the V-shaped notch as the reference, thereby forming bending groove II, so as to facilitate the bending of the right-angle flange.

[0021] See appendix Figure 3 , 4 As shown in Figures 5 and 6, the right-angle bent structure of the aluminum honeycomb panel of this utility model can be manufactured using the following steps:

[0022] S1. Using a flat milling cutter, a section with a width of [missing information] is machined along the bending line on the front panel of the aluminum honeycomb panel to be bent. The notch 3-1; wherein, the distance from the right edge of the notch to the vertical plane containing the bend line is 1 mm; the bend line refers to the outer apex angle line of the right angle formed after the aluminum honeycomb panel to be bent at a right angle; wherein, h 1 The thickness of the aluminum honeycomb panel to be bent is 1-3mm. The purpose of this step is to remove the top panel on the left side of the bend line, while retaining the top right panel bent into a right-angle flange. The 1-3mm deviation is mainly to avoid the cutter shank of the tapered milling cutter. See appendix. Figure 3 .

[0023] S2. Using a tapered milling cutter, a V-shaped notch 3-2 with a 90-degree apex angle and symmetrical left and right sides is machined along the bending line on the aluminum honeycomb panel to be bent; during machining, the upper end face of the tapered milling cutter is located on the lower surface of the upper panel of the aluminum honeycomb panel to be bent, so that the upper panel of the aluminum honeycomb panel to be bent on the right side of the V-shaped notch is retained; and the apex angle of the V-shaped notch extends 0.1-0.3mm into the upper surface of the lower panel of the aluminum honeycomb panel, thereby forming a bending groove I 3-3; see Appendix Figure 4 .

[0024] S3. Bend the upper panel on the right side of the V-shaped notch of the aluminum honeycomb panel to be bent upwards at a 90-degree angle, using the edge of the V-shaped notch as a reference, to form a right-angle flange 3-4, and apply adhesive to the left surface of the right-angle flange; wherein, the edge of the V-shaped notch refers to the straight line formed by the intersection of the inclined surface of the V-shaped notch and the upper surface of the upper panel on the right side of the aluminum honeycomb panel to be bent; see appendix. Figure 5 .

[0025] S4. Bend the left side of the V-shaped notch of the aluminum honeycomb panel to be bent 90 degrees to the right. At this point, the upper surface of the left side of the panel should be in close contact with the left surface of the right-angle flange. Since the bending groove I has been processed in step S2, the overall bending should be smooth and there should be no deviation or bending of the bending line. See Appendix. Figure 6 .

[0026] S5. Maintain the bending force and wait for the adhesive to dry; thus, the right-angle bend of the aluminum honeycomb panel is completed.

[0027] As a preferred technical solution, in step S3, no adhesive is applied to the left surface of the right-angle flange. Instead, in step S4, when the upper surface of the left side of the V-shaped notch of the aluminum honeycomb panel to be bent is in close contact with the left surface of the right-angle flange, laser welding is used to weld the upper surface of the left side of the V-shaped notch of the aluminum honeycomb panel to be bent together with the right-angle flange. Using welding to weld the upper surface of the left side of the V-shaped notch of the aluminum honeycomb panel to be bent together with the right-angle flange further ensures the strength and rigidity of the right-angle bending structure.

[0028] As one of the preferred technical solutions, an additional process is added before step S3: a 0.1-0.3mm groove is machined on the upper plate to the right of the V-shaped notch of the aluminum honeycomb panel to be bent, using the edge line of the V-shaped notch as a reference. This forms bending groove II. Adding bending groove II is to guide the right-angle bend in step S3, making the bend more regular and effective, and ensuring the bending quality.

[0029] The beneficial technical effect of this utility model's aluminum honeycomb panel right-angle bending structure is that it replaces the right-angle assembly structure with a right-angle bending structure, fundamentally solving the problems of aluminum honeycomb panels being unable to withstand large lateral forces and having loose internal structure, ensuring the right-angle bending strength and rigidity, and guaranteeing the service life of aluminum alloy furniture.
