Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of container welding, in particular to a welded container thin plate bending skin structure. Background Art
[0002] The outer skin (exterior surface sheet material) of a container is typically used to protect the cargo inside the container and provide sufficient strength and durability for the container as a whole. In the current container manufacturing industry, different types of sheet materials are used as outer skins, two of which are common: corrugated sheet (also known as corrugated sheet) and flat sheet.
[0003] When using corrugated sheet as the outer skin sheet, the characteristic of the corrugated sheet is that its surface presents a regular corrugated shape. These corrugations increase the rigidity and bending resistance of the sheet. However, when corrugated sheet is used in special equipment containers, it is often divided into many blocks. The design of each block lacks visual consistency and coherence. In addition, the production cost of corrugated containers is low. Although the cost of using flat panels to make containers is low, due to the material properties of the flat panels themselves, which are made of aluminum, and in order to reduce the space occupied by the outer skin, the thickness of the outer skin is generally thinner. Thinner aluminum has worse resistance to welding deformation. In other words, the skin of flat-bed containers has poor resistance to welding deformation. After welding, the outer skin will locally undergo wave deformation, which not only has poor quality, but also greatly affects the appearance quality after painting.
[0004] Especially when a thinner flat panel is used as the outer skin, the flatbed container is more prone to deformation at the bends. Specifically, the outer surface frame structure of the container includes four columns and a bottom plate; the columns are fixedly mounted on the four end corners of the bottom plate to form the outer frame of the container, and the outer skin is mounted on the outer frame to form a closed box. When the outer skin and the columns are connected, the outer skin will bend, and the bend is concave relative to the columns, and the outer skin is connected to the columns at the bend. In the prior art, the outer skin is usually abutted against the columns at the bend, and then the structural relationship between the outer skin and the columns is fixed by gluing and riveting. However, gluing involves issues of waterproofness and lifespan. When gluing is used for fixing, cracks will appear between the outer skin and the columns within 3 years of use (generally, the service life of the container is 15 years). After cracking, it is easy for the riveted joints to bend or even break, weakening the sealing of the container. It is not only easy for the inside of the container to get damp, but also seriously affects the pressure resistance and service life of the horizontal container. Utility Model Content
[0005] This basic solution provides a welded container thin plate bent skin structure, which aims to solve the problem of deformation of the container flat plate skin after welding and improve the service life of the container.
[0006] A welded container thin plate bent skin structure, the container outer surface frame includes a bottom plate and multiple columns, the columns are fixedly installed on the end corners of the bottom plate, and include an outer skin and multiple reinforcing ribs; the thickness of the outer skin does not exceed 1.5 mm; the outer skin is arranged in the space formed by each column; the outer skin includes a flat skin and a bent skin; the flat skin is arranged between two adjacent columns; the bent skin connects the two adjacent flat skins and is arranged on the inner side of each column; a welding area is left between the bent skin and the column, and welding is used between the bent skin and the column; one end of the reinforcing rib is fixedly connected to the inner surface of the bent skin, and the other end is fixedly connected to the inner surface of the flat skin.
[0007] Beneficial effects: Compared with the existing technology, since the flat-bed container skin has poor resistance to welding deformation, local wave deformation will occur after welding, especially when the flat plate is thin, the bending parts of the flat-bed container are more prone to deformation. Therefore, the flat-bed container is fixed and installed by gluing and riveting, which shortens its service life. The service life of the container is generally more than ten years, so the maintenance cost of the container is high.
[0008] This basic solution overcomes the defects of the existing technology. First, due to the inherent material properties of the outer skin of the flat-bed container, its outer skin has poor resistance to welding deformation, especially the bent skin has the worst resistance to welding deformation. This solution leaves sufficient welding area between the bent skin and the column, reduces the stress on the welding structure, prevents skin deformation, strengthens the stability and firmness of the bent skin, and improves the sealing of the outer skin, thereby increasing the service life of the container.
[0009] Secondly, reinforcing ribs are fixed between the inner surface of the bent skin and the flat skin. This not only increases the structure's resistance to welding deformation and plays a role in stability, but also increases the firmness of the outer skin structure and extends the service life of the container.
[0010] Moreover, even if the thickness of the outer skin does not exceed 1.5 mm, this solution can be used for welding, which has wide applicability and meets the purpose of lightweighting the container.
[0011] Finally, the adoption of this solution not only allows the use of a thinner outer skin to reduce the overall mass of the container and the space volume occupied by the outer skin, but also leaves a welding area and a method for installing reinforcing ribs. Compared with the space volume of the entire container, the space volume occupied by the container is smaller; and compared with the method of using glue and riveting, the maintenance frequency is less and the maintenance cost is lower, the container is stronger and has a longer service life.
[0012] Preferably, the bent skin and the column are connected by full welding.
[0013] Beneficial effects: The full weld has high strength and sealing, which can ensure the integrity and reliability of the welded parts.
[0014] Preferably, one end of the reinforcement rib is welded to the inner surface of the bent skin, and the other end of the reinforcement rib is welded to the inner surface of the planar skin.
[0015] Beneficial effect: By installing the reinforcing ribs, the bending skin can be prevented from deformation and the firmness of the outer skin can be enhanced.
[0016] Preferably, the reinforcement ribs and the outer skin are connected by spot welding.
[0017] Beneficial effects: Spot welding has a fast speed and high production efficiency, which is very suitable for large-scale production. In addition, spot welding does not require filler materials, so the welding cost is low.
[0018] Preferably, there are at least 8 reinforcing ribs.
[0019] Beneficial effect: It further prevents the bending skin from deformation and also strengthens the firmness of the outer skin.
[0020] Preferably, the width of the welding area is not less than 40 mm.
[0021] Beneficial effect: sufficient welding area is left to ensure good strength and sealing of the welding parts.
[0022] Preferably, the outer surface of the planar skin is flush with the outer surface of the pillar.
[0023] Beneficial effect: more internal space of the container is left for loading goods without taking up too much space of the container.
[0024] Preferably, the bent skin is in a right-angle shape.
[0025] Beneficial effect: easy to weld with the column.
[0026] Preferably, the outer skin is an aluminum sheet.
[0027] Beneficial effects: Aluminum has a lighter density, about one-third of steel. Using aluminum plates can significantly reduce the weight of the container, thereby reducing transportation costs and improving transportation efficiency.
[0028] Beneficial effects of the utility model
[0029] Compared to the prior art, when the outer skin is directly mounted on the outer surface frame of a container with an outer skin thickness not exceeding 1.5mm, if the outer skin and the column are directly connected by welding, it is not easy to weld them tightly due to the small thickness of the outer skin. In addition, due to the influence of the outer skin itself being an aluminum plate, its resistance to welding deformation is relatively poor, and deformation is easily caused at the bent skin. First, the utility model bends the outer skin when it is close to the column, that is, it is set as a bent skin, leaving a welding area with a width of not less than 4mm between the bent skin and the column. A full welding method is used between the welding areas to firmly fix the bent skin and the column together. In this way, deformation of the bent skin is avoided, and the strength of the outer skin is also improved, thereby extending the service life of the container.
[0030] Secondly, reinforcing ribs are spot-welded between the inner surface of the bent skin and the inner surface of the flat skin. The reinforcing ribs can further prevent the bent skin from deforming and at the same time improve the firmness and stability of the outer skin.
[0031] Finally, the welding method, compared with the gluing and riveting method, although it occupies a certain space volume, it occupies less space volume compared with the overall container volume. However, the welding method makes the container stronger, has a longer service life, requires fewer repairs, and has low maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Example
[0040] This embodiment provides a welded container thin plate bent skin structure that can solve the problem of poor resistance to welding deformation at the bends of flatbed containers with an outer skin 3 thickness not exceeding 1.5 mm and wave deformation after welding. The outer skin 3 is an aluminum plate.
[0041] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, the outer surface frame of the container includes a rectangular bottom plate 4 and four columns 1. The four end corners of the rectangular bottom plate 4 are fixedly mounted with columns 1. A welded container thin plate bent skin 31 structure includes an outer skin 3, a welding area 2 and a reinforcing rib 5. The outer skin 3 includes a bent skin 31 and a flat skin 32. Figure 1 As shown, the upper surface of the outer skin 3 is a flat skin 32, which is in the shape of a rectangular cutoff. That is, at each corner of the outer skin 3, the original sharp right angle is replaced by a small rectangular notch. Figure 3 As shown, the plane skin 32 is also the side surfaces of the outer skin 3. The bent skin 31 includes a bent outer surface and an inner surface of the bent skin 31. The plane skin 32 includes an outer surface of the plane skin 32 and an inner surface of the plane skin 32. The difference between the outer surface and the inner surface is that the outer surface refers to the part observed from the outside of the container, and the inner surface refers to the part observed from the inside of the container. There are 5 plane skins 32, which are the front, back, left, right and top of the container, and their outer surfaces are flush with the outer surfaces of the front, back, left, right and top of the column 1. There are 4 bending skins 31, with a total of 8 faces. The plane skin 32 is arranged between two adjacent columns 1; the bending skin 31 connects the two adjacent plane skins 32 and is arranged on the inner side of each column 1. As shown Figure 1 and Figure 3 As shown, the bent skin 31 faces away from the pillar 1 and is in a concave right-angle shape, that is, the two adjacent surfaces of each bent skin 31 are in a vertical structure.
[0042] like Figure 4 As shown, there are at least 8 reinforcing ribs 5. The reinforcing ribs 5 are installed between the inner surface of the bent skin 31 and the inner surface of the flat skin 32. One end of the reinforcing rib 5 is welded to the inner surface of the bent skin 31 by spot welding, and the other end of the reinforcing rib 5 is welded to the inner surface of the flat skin 32 by spot welding.
[0043] like Figure 5 As shown, Figure 5This is a schematic diagram of the container columns 1, outer skin 3, and welding area 2 after being unfolded to form a plane. The outer surface of the flat skin 32 is flush with the outer surfaces of the four columns 1, and the outer surface of the bent skin 31 is opposite to the columns 1. A welding area 2 is left between the columns 1 and the bent skin 31. The columns 1 and the bent skin 31 are connected by welding, and the welding area 2 is a full weld. Figure 1 and Figure 2 As shown, the distance between the bent skin 31 and the pillar 1 is at least a, a=40 mm, that is, the length of the welding area 2 is a, a=40 mm.
[0044] In this embodiment, the bent skin 31 and the flat skin 32 together constitute the outer skin 3, that is, the outer skin 3 is divided into two parts, the flat skin 32 and the bent skin 31, and the two are integrated to form the outer skin 3. It can also be said that the flat skin 32 and the bent skin 31 are fixedly connected.
[0045] Installation method of this embodiment
[0046] The bent skin 31 and the flat skin 32 form an integrated outer skin 3 structure, namely, they are fixedly connected. First, the bottoms of the flat skins 32 located on the front, back, left, and right sides of the container are fixedly connected to the rectangular base plate 4, which can be welded. A welding area 2 is provided between the bent skin 31 and the column 1. The bent skin 31 and the column 1 are connected by welding, and the welding area 2 is fully welded. The outer surface of the flat skin 32 is flush with the outer surface of the column 1.
[0047] Secondly, after the column 1 and the outer skin 3 are assembled in place, the inner surface of the bent skin 31 and the inner surface of the flat skin 32 are connected by reinforcing ribs 5, which can be connected by spot welding.
[0048] Beneficial effects of this embodiment
[0049] The reinforcing ribs 5 are installed between the inner surface of the bent skin 31 and the inner surface of the flat skin 32, reinforcing the bent skin 31 and increasing the container structure's resistance to welding deformation. A welding area 2 is provided between the bent skin 31 and the column 1, allowing a full weld connection between the outer surface of the bent skin 31 and the column 1, reducing the stress on the welded structure and preventing deformation of the outer skin 3.
