Description

Technical Field

[0001] The utility model relates to the technical field of container production, and more specifically, to a container short bottom beam processing structure. Background Art

[0002] The existing short bottom beam of the container is formed by punching and bending a 4.5mm thick steel plate. The welding surface is connected to the bending edge, which causes the welding surface to be too close to the bending line, with a distance of about 2mm. When the bent short bottom beam is assembled with the gooseneck groove, there is an obvious welding gap between the welding surface and the gooseneck groove, which is similar in size to the thickness of the plate, about 4.5mm. Not only is welding difficult and requires a high amount of welding materials, but welding is also time-consuming and has a poor forming effect. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a container short bottom beam processing structure to solve one or more of the above-mentioned problems.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The container short bottom beam processing structure comprises a main board, an upper fold line and a lower fold line are arranged on the main board, an outwardly convex welding surface is arranged on the front end surface of the main board, an arc-shaped groove is opened between the welding surface and the upper fold line, the top of the welding surface is raised to form a table top, the main board is bent along the upper fold line and the lower fold line to form a short bottom beam with a C-shaped cross-section, and the short bottom beam is assembled and welded with the gooseneck groove through the welding surface to form a welding gap.

[0006] Furthermore, the distance between the upper fold line and the top surface of the main board is smaller than the distance between the lower fold line and the bottom surface of the main board.

[0007] Furthermore, the top of the welding surface is higher than the upper fold line, and the bottom of the welding surface is flush with the bottom of the mainboard.

[0008] Furthermore, the welding surface is composed of a top horizontal surface, a middle inclined surface and a bottom vertical surface, and the junctions between the top and the middle, and between the middle and the bottom of the welding surface are chamfered.

[0009] Furthermore, the welding gap includes an arc groove gap between the arc groove and the gooseneck groove, an arc surface gap between the junction of the top and middle of the welding surface and the gooseneck groove, and an arc surface gap between the junction of the middle and bottom of the welding surface and the gooseneck groove.

[0010] Furthermore, the table top at the top of the welding surface is 6.4 mm higher than the upper fold line, and the radius of the arc-shaped groove is 3 mm.

[0011] In summary, the utility model has the following beneficial effects: by opening an arc-shaped notch between the welding surface and the bending edge and raising the welding surface, the distance from the bending line is increased to ensure that the welding surface will not be deformed during bending. At the same time, the welding gap during assembly of the short bottom beam and the gooseneck groove after forming is greatly reduced, thereby reducing the welding difficulty, reducing the use of welding materials, shortening the welding time, and improving the forming effect.

[0019] Example:

[0020] The following is combined with Figure 1-6 The utility model is described in further detail.

[0021] Existing container end bottom beams such as Figure 3 and Figure 4 As shown, the short bottom beam 7 is a main board 1 before being bent and formed. The main board 1 has an upper fold line 2 and a lower fold line 3. The front end of the main board 1 is a welding surface 4. The welding surface 4 is divided into a horizontal surface, an inclined surface and a vertical surface. The main board 1 is bent along the upper fold line 2 and the lower fold line 3 to form a short bottom beam 7. Then, a gooseneck groove 8 is assembled and welded on the welding surface 4. The gooseneck groove 8 and the welding surface 4 are at the intersection of the three sections of the welding surface 4 because of the corner. The height of the welding gap 9 is the thickness of the main board 1, which is generally 4.5 mm. The vertical spacing between the top of the welding surface 4 and the upper fold line 2 is 2 mm. The welding gap 9 formed in this way is too large, which affects the quality of welding.

[0022] The processing structure of the container short bottom beam 7 is as follows: Figure 1 , Figure 2 and Figure 6 As shown, an upper fold line 2 and a lower fold line 3 are designed on the main board 1. The distance between the upper fold line 2 and the top surface of the main board 1 is smaller than the distance between the lower fold line 3 and the bottom surface of the main board 1. In this way, after bending, the width of the upper fold line 2 is smaller than the width of the lower fold line 3, which can meet the use requirements of the short bottom beam 7. The front end surface of the main board 1 is provided with a convex welding surface 4, which starts from the upper fold line 2 to the bottom surface of the main board 1, that is, the top of the welding surface 4 is higher than the upper fold line 2, and the bottom of the welding surface 4 is parallel to the bottom of the main board 1. The welding surface 4 is specifically divided into three sections, the horizontal surface at the top, the inclined surface in the middle and the vertical surface at the bottom. The junction between the top and the middle of the welding surface 4 and the junction between the middle and the bottom of the welding surface 4 are all chamfered to facilitate subsequent welding. The connection between the welding surface 4 and the main board 1 can also be approximately regarded as the junction between the welding surface 4 and the upper fold line 2, and an arc groove 5, that is, a circular notch, is provided, and the radius of the notch is 3mm. The notch continues to form a table top 6 formed by raising the top of the welding surface 4, and the table top 6 is set 26.4mm higher than the upper fold line.

[0023] The main board 1 is bent along the upper fold line 2 and the lower fold line 3 to form a short bottom beam 7. The short bottom beam 7 is a C-shaped cross-section structure. The short bottom beam 7 is assembled and welded with the welding surface 4 and the gooseneck groove 8 to naturally form a welding gap 9. In the welding gap 9, the arc gap between the junction of the middle and bottom of the welding surface 4 and the gooseneck groove 8 is the same as the existing situation, but the sum of the arc gap between the arc groove 5 and the gooseneck groove 8 and the arc gap between the junction of the top and middle of the welding surface 4 and the gooseneck groove 8 is obviously lower than the existing welding gap 9 between the gooseneck groove 8 and the upper end of the welding surface 4. This is not only conducive to saving welding consumables and reducing welding difficulty, but also conducive to improving the molding effect and facilitating welding assembly.

[0024] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
