However, these welding operations often cause welding deformation of the position of the entire container barrel, especially the discharge port flange, which seriously affects the precision and performance of the equipment.
[0035] The present application will be further described below in conjunction with the drawings and embodiments.
[0036] Figure 2 A cooperation schematic diagram of the container barrel welding deformation prevention tool and the container barrel provided by one exemplary embodiment of the present application is shown, Figure 3 A structure schematic diagram of the container barrel welding deformation prevention tool provided by one exemplary embodiment of the present application is shown.
[0037] In detail, the container barrel welding anti-deformation tool can adjustably fit the inner wall of the container barrel 1, and comprises a front end arc plate 5, an end head 6, a central shaft 8, a sleeve 10, a support rod 11, and a rear end arc plate 14. The first end of the front end arc plate 5 has an arc surface matching the inner wall of the container barrel 1. The first end of the end head 6 is connected to the second end of the front end arc plate 5. The first end of the central shaft 8 is movably connected to the second end of the end head 6. The first end of the sleeve 10 is threadedly connected to the second end of the central shaft 8, so that the overall length of the container barrel welding anti-deformation tool can be adjusted by rotating the central shaft 8. The first end of the support rod 11 is connected to the second end of the sleeve 10. The first end of the rear end arc plate 14 is hingedly connected to the second end of the support rod 11, and the second end of the rear end arc plate 14 has an arc surface matching the inner wall of the container barrel 1. The position of the front end arc plate 5 corresponds to the position of the welding outlet flange 2 on the container barrel 1.
[0038] In the embodiment, the first end of the sleeve 10 is threadedly connected to the second end of the central shaft 8 (specifically, the first end of the sleeve 10 is internally threaded, and the second end of the central shaft 8 is externally threaded). The overall length of the container barrel welding anti-deformation tool can be shortened by rotating the central shaft 8 to extend the second end of the central shaft 8 into the interior of the sleeve 10, or vice versa.
[0039] In the embodiment, the central shaft 8 has a plurality of through holes 16 for inserting a lever to rotate the central shaft 8, so that the container barrel welding anti-deformation tool can be quickly clamped and disassembled.
[0040] In the embodiment, the front end arc plate 5 and the rear end arc plate 14 are used to control welding deformation during welding to ensure the roundness of the barrel. The front end arc plate 5 and the rear end arc plate 14 can be replaced according to different sizes of the barrel, thereby saving material and processing costs.
[0041] In some embodiments, the threaded connection between the first end of the sleeve 10 and the second end of the central shaft 8 can be locked by a lock nut 9, so as to lock and maintain the overall length of the container barrel welding anti-deformation tool after adjustment.
[0042] Further, the first end of the central shaft 8 is rotatably connected to the second end of the end head 6 through a bushing 7, so as to cooperate with the rotation of the central shaft 8.
[0043] Specifically, the first end of the rear end arc plate 14 is hingedly connected to the second end of the support rod 11 through a hinge block 13 and a positioning pin 12. In addition, the support rod 11 has two groups, and the two groups of support rods 11 are symmetrically distributed along the central axis of the sleeve 10.
[0044] In the embodiment of the present application, the two groups of support rods 11 are arranged in a V shape, and the hinge connection of the rear end arc plate 14 with the support rods 11 can ensure that the rear end arc plate 14 is tightly attached to the inner wall of the container barrel 1 when the welding anti-deformation tool for the container barrel is adjusted in overall length.
[0045] It is worth mentioning that, in order to facilitate the welding of the discharge port flange 2, the inner side of the end head 6 is hollow, and the lower part of the front end arc plate 5 and the lower part of the first end of the end head 6 are provided with arc-shaped notches 15 for facilitating the welding of the discharge port flange 2.
[0046] It should be noted that, in order to better attach the rear end arc plate 14 to the inner wall of the container barrel 1, Figure 4 The cross-sectional structure of the hinge block and the rear end arc plate of the welding anti-deformation tool for the container barrel is shown in the embodiment of the present application, one end of the hinge block 13 close to the rear end arc plate 14 is provided with a groove 131, the groove 131 is provided with a movable column 132, the outer periphery of the movable column 132 is provided with an annular guide groove 133, and the movable column 132 can rotate in the groove 131 by inserting a positioning bolt 134 into the side wall of the hinge block 13 and cooperating with the annular guide groove 133, and the movable column 132 is connected to the rear end arc plate 14 by a fixing screw 135.
[0047] In the embodiment of the present application, since the positioning bolt 134 is inserted into the annular guide groove 133, the movable column 132 can only rotate and cannot move axially, when the rear end arc plate 14 needs to be replaced, the positioning bolt 134 is first unscrewed, the rear end arc plate 14 can be taken out with the movable column 132, and then the fixing screw 135 is unscrewed to replace the rear end arc plate 14.
[0048] Next, the working principle of the welding anti-deformation tool for the container barrel in the embodiment of the present application is described.
[0049] When the container barrel 1 and the bottom plate 4 need to be welded and the container barrel 1 and the discharge port flange 2 need to be welded, the tool is placed above the bottom plate 4, the radial parallelism of the tool with the bottom plate 4 and the container barrel 1 is adjusted, the position of the front end arc plate 5 is aligned with the discharge port flange 2 and attached to the inner wall of the container barrel 1, the overall length of the tool is elongated by rotating the central shaft 8, until the rear end arc plate 14 is attached to the inner wall of the container barrel 1, and finally the lock nut 9 is tightened, and the welding can be started.
[0050] In summary, the tooling combines the size requirements of the inner wall of the container barrel and the discharge port flange, strictly adheres to the heat-affected zone which is more likely to deform during the welding process, controls the welding deformation, meets the size requirements, reduces the time and difficulty of shaping, and reduces the production cost. Specifically, according to the welding requirements of the container bottom, the welding deformation of the easily deformed area of the container is controlled through the tooling under the condition of leaving sufficient operation space, the post-welding size qualified rate of the container is effectively ensured, and large welding deformation is avoided; the size and weight of the tooling can be directly operated by personnel without auxiliary tools, the operation is simple and does not require prior calculation, the operation time is reduced, and the operation efficiency is improved; the tooling structure is simple, easy to install, and low in manufacturing cost, and has good adaptability to equipment, and by replacing the arc plate and adjusting the sleeve, the welding of the bottom plate of containers of different sizes can be completed, and the tooling has good universality and stability, and the production cost is reduced.

For ordinary skilled persons in the art, the specific meanings of the above terms in the embodiments disclosed in the present application can be understood according to the specific circumstances.
[0052] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the art, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered within the protection scope of the present application.
