An accordion-style granular arc bending plate

Abstract

This utility model relates to an arc-shaped plate, and more particularly to an accordion-grain arc-shaped bending plate, solving the structural design problem of arc-shaped plates. It includes a first surface layer, a bending layer, and a second surface layer bonded together in sequence. Both the first and second surface layers are arc-shaped structures, with the circumference of the first surface layer being smaller than that of the second surface layer. The bending layer is composed of several bending substrates, with the first and second surface layers located at opposite ends in the height direction of the bending substrates. The end of each bending substrate facing the second surface layer is the outer end, and the end facing the first surface layer is the inner end. The inner ends of the bending substrates are adjacent to each other, while the outer ends of the bending substrates have a clearance. This design lowers the cost of the arc-shaped process, increases speed, reduces the curvature, and maintains stability as expected. Using an accordion-grain arc-shaped bending plate for the arc portion of the product and a regular particleboard for the straight edge better meets user needs.

Description

Technical Field

[0001] This utility model relates to an arc plate, and more particularly to an accordion-shaped arc bending plate. Background Technology

[0002] There are roughly three methods for producing curved sheet materials, each suitable for different applications. One method involves direct one-piece molding, which is costly but relatively fast. Another method uses end milling to allow the sheet to bend, with the degree of bending increasing as the number of grooves increases. A third method uses multi-layer boards for hot pressing, but this is prone to stress-induced deformation and other defects after prolonged use. There is a lack of a structurally stable and easily processed product to meet production needs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an accordion-shaped particle arc bending plate.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an accordion-shaped granular arc-shaped bending plate, comprising a first surface layer, a bending layer, and a second surface layer bonded together in sequence. Both the first surface layer and the second surface layer are arc-shaped structures. The circumference of the first surface layer is smaller than that of the second surface layer. The bending layer is composed of several bending substrates. The first surface layer and the second surface layer are located at opposite ends in the height direction of the bending substrates. The end of the bending substrate facing the second surface layer is the outer end, and the end of the bending substrate facing the first surface layer is the inner end. The inner ends of the bending substrates are adjacent to each other, and there is a clearance between the outer ends of the bending substrates.

[0005] The bending matrix is ​​formed by hot pressing wood particles together.

[0006] The clearance of the bending layer gradually decreases from the center to both sides.

[0007] The first surface layer has a fixed base surface on the end face facing the bending layer, and the second surface layer has a shaping base surface on the end face facing the bending layer.

[0008] The gaps between the remaining portions are filled with adhesive.

[0009] The allowance gap between the bent substrates gradually decreases from the outer end to the inner end.

[0010] The beneficial effects of this utility model are as follows: The accordion-shaped particle arc bending plate provided by this utility model makes the arc process cheaper, faster, and with a smaller arc, and the stability also meets the design expectations. The arc part of the product is made of accordion-shaped particle arc bending plate, while the straight edge part is made of ordinary particle plate, which can better meet the user's needs.

[0012] like Figure 1 As shown, an accordion-shaped granular arc-shaped bending board improves upon the defects in current arc-shaped board manufacturing from a structural design perspective, and therefore adopts a matching process for production. In this embodiment, the bending layer 2 needs to be first bonded and fixed to the first surface layer 1, and then bent and deformed so that the first surface layer 1 forms an arc structure and one end of the bending layer 2 gradually unfolds to form an accordion shape. It should be noted that the accordion shape is also similar to a fan-shaped structure, but in this embodiment, the bending base is of equal height. It includes a first surface layer 1, a bending layer 2, and a second surface layer 3 bonded together in sequence. Both the first surface layer 1 and the second surface layer 3 are arc-shaped structures, and the perimeter of the first surface layer 1 is smaller than that of the second surface layer 3. In the finished product, the first surface layer 1 is located on the inside, while the second surface layer 3 is located on the outside, so the arc edge of the first surface layer 1 is shorter than that of the second surface layer 3. From another perspective, the first surface layer 1 and the second surface layer 3 are of equal height and width, with only differences in size at the arc edge. The bending layer 2 is composed of several bending substrates. The first surface layer 1 and the second surface layer 3 are located at opposite ends of the bending substrates in the height direction. The end of the bending substrate facing the second surface layer 3 is the outer end 4, and the end of the bending substrate facing the first surface layer 1 is the inner end 5. The inner ends 5 of the bending substrates are adjacent to each other, and there is a clearance 6 between the outer ends 4 of the bending substrates. In actual production, the bending substrates are bonded side by side to the first surface layer 1, and the initial state between the bending substrates should be a non-bonded state, otherwise it will affect subsequent bending operations. The end face of the first surface layer 1 facing the bending layer 2 is a fixed base surface 7, and the end face of the second surface layer 3 facing the bending layer 2 is a shaping base surface 8. In this embodiment, the first surface layer 1 is the main fixed base surface 7, playing the most basic fixing role, while the second surface layer 3 plays an auxiliary shaping role. The denser the bending substrate of the bending layer 2, the smaller the allowance gap 6, the more stable the structure, and the less adhesive is used. Unlike the direct hot-pressing deformation of traditional multilayer boards, the presence of the allowance gap 6 in this embodiment can effectively offset stress, improving service life and stability. At the same time, the processing difficulty is reduced, improving bending quality and efficiency.

[0013] The bent substrate is formed by hot-pressing and bonding wood particles, unlike multi-layer wood structures. This embodiment has a higher density and lower stress, further improving stability and durability based on the accordion-shaped structure. The excess gap 6 of the bent layer 2 gradually decreases from the center to both sides, and the excess gap 6 between the bent substrates gradually decreases from the outer end 4 to the inner end 5, forming an accordion-like structure, ensuring structural strength and stability, and facilitating processing and production. The excess gaps 6 are filled with adhesive, which can be partially compensated for by using excess adhesive when bonding the second surface layer 3, rather than requiring complete filling.

Therefore, they should not be construed as limitations on this utility model. At the same time, the basic principles, main features, and advantages of this utility model have been shown and described above, which should be understood by those skilled in the art.
