[0025] The tank shaping machine of this utility model has the following advantages over the prior art:

[0026] (1) By setting a fixed seat and passing the boom through the fixed seat, the tank shaping machine can be mounted on the heating furnace by relying on the fixed seat, which makes it convenient for the worktable and drive head to shape the tank wall; at the same time, due to the through structure, the length of the part of the boom located below the fixed seat can be reduced, which makes it suitable for shaping tanks near the tank opening and expands the shaping range.

[0027] (2) The boom is mounted on the fixed seat by the lifting cylinder, and the lifting cylinder and the two positioning brackets form a rectangular frame structure and are set as an integral structure.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0033] like Figure 1 As shown, the tank shaping machine of this utility model includes a fixed base 1, a large arm 2, a worktable 3, a drive head 4, a lifting cylinder 5, a hinge support 6, a positioning bracket 7, a positioning cylinder 8, and a shaping mold 100.

[0034] like Figure 1 As shown, the fixed base 1 is used for positioning; the upper arm 2 is slidably mounted on the fixed base 1 and passes through the fixed base 1; the worktable 3 is mounted on the upper arm 2 and a shaping mold 100 is mounted on the worktable 3; the drive head 4 is slidably mounted on the upper arm 2 and is used to drive the shaping mold 100 to expand.

[0035] As described above, when shaping the tank, the tank is first placed in a heating furnace for heating. Then, the shaping machine is hoisted onto the heating furnace, and the fixed base 1 is attached to the port flange of the heating furnace. The boom 2 extends into the tank to be shaped, and then the drive head 4 moves, thereby driving the shaping mold 100 to expand. The shaping mold 100 pushes against the inner wall of the tank, thereby realizing the shaping work.

[0036] Specifically, the drive head 4 uses hydraulic cylinders, air cylinders and other moving parts, and drives the shaping mold 100 to slide on the worktable 3 through the connecting rod, so that the inner wall of the tank can be moved by the shaping mold 100.

[0037] Because this tank shaping machine adopts a through-type structure, the length of the part of the upper arm 2 located below the fixed base 1 can be reduced, thus making it suitable for shaping the position near the tank opening and expanding the shaping range.

[0038] Specifically, the shaping mold 100 is set on the worktable 3 in a plug-in manner.

[0039] like Figure 1 As shown, there is one lifting cylinder 5 on each side of the boom 2; there are two hinge supports 6 on the fixed base 1, and they are connected to the movable end of the lifting cylinder 5.

[0040] As described above, the boom 2 is driven by a lifting cylinder 5, which allows it to extend and retract on the fixed base 1. The movable end of the lifting cylinder 5 is connected to the fixed base 1 via a hinge support 6 to ensure ease of assembly.

[0041] like Figure 1 As shown, there are two positioning brackets 7 on the boom 2; two lifting cylinders 5 are connected to one of the positioning brackets 7 and pass through the other positioning bracket 7;

[0042] As described above, the boom 2 is equipped with a positioning bracket 7 for connecting the lifting cylinder 5; there are two positioning brackets 7, which can fix both ends of the sleeve part of the lifting cylinder 5, thereby ensuring the stability of the structure.

[0043] like Figure 1 As shown, the two positioning brackets 7 are parallel, the two lifting cylinders 5 are parallel, the lifting cylinders 5 are perpendicular to the surface of the positioning brackets 7, and the positioning brackets 7 and the lifting cylinders 5 are assembled into an integrated structure.

[0044] As described above, by assembling the positioning bracket 7 and the lifting cylinder 5 into an integrated structure, a rectangular frame structure is formed. This structure not only helps to ensure the relative structural stability of the positioning bracket 7 and the lifting cylinder 5, but also facilitates connection with the boom 2 to ensure the relative positional accuracy of each component, thereby improving the shaping accuracy.

[0045] like Figure 1 As shown, the positioning bracket 7 is a plate-like structure or a frame-like structure, and the upper arm 2 passes through the positioning bracket 7 and is relatively fixed.

[0046] As described above, the positioning bracket 7 adopts a plate-like structure or a frame-like structure. The two positioning brackets 7 are parallel. When the main arm 2 is installed, the main arm 2 is passed through the positioning bracket 7 and connected and fixed with bolts or other fasteners. In this way, it is convenient to disassemble, repair or replace the positioning bracket 7 when it is deformed or damaged.

[0047] like Figure 1 As shown, there are two positioning cylinders 8 on the fixed base 1, and the movable end of the positioning cylinder 8 passes through the fixed base 1;

[0048] As described above, the positioning cylinder 8 is used for positioning in this tank shaping machine. After the tank shaping machine is hoisted onto the heating furnace, the movable end of the positioning cylinder 8 is inserted and positioned with the flange of the heating furnace pipe.

[0049] In some embodiments, the movable end of the positioning cylinder 8 is inserted and positioned with the flange of the tank to be shaped.

[0050] like Figure 1 As shown, the fixing base 1 has a plate-like structure, and a through hole is provided in the middle of the fixing base 1 for the large arm 2 to pass through.

[0051] As described above, the fixing base 1 is set as a plate structure, and a through hole is opened in the middle for the upper arm 2 to pass through;

[0052] Specifically, the mounting base 1 can be set to a circular, rectangular, or other structure, depending on the specific application.

[0053] like Figure 1 As shown, the boom 2 includes an upper arm 21 and a lower arm 22. The upper arm 21 is connected to the lifting cylinder 5 and has a built-in hydraulic station and electrical components. The lower arm 22 is located at the lower end of the upper arm 21 and is connected to the worktable 3 and the drive head 4.

[0054] As described above, the boom 2 is divided into two parts: the upper boom 21 and the lower boom 22. The upper boom 21 is used to house the hydraulic station and electrical components to supply hydraulic oil and electricity to the components, thus improving the overall compactness of the structure.

[0055] Meanwhile, the upper arm 22 is located above the fixed base 1, which reduces the impact of temperature on the internal hydraulic station and electrical components, thus ensuring the stability of the application; the lower arm 22 is used to install the worktable and drive head 4, and to house the moving parts for driving the drive head 4.

[0056] Specifically, the minimum distance between the upper end face of the shaping mold 100 and the lower end face of the fixing base 1 is 300mm, and the maximum distance is 1500mm; the thickness of the shaping mold 100 is 100-300mm.

[0057] As described above, by controlling the parameters, this tank shaping machine can shape the parts of the tank most prone to deformation, thereby ensuring the application effect.

[0058] Specific implementation steps:

[0059] After the tank to be shaped is placed in the heating furnace and heated to 850℃~1000℃, the tank shaping mechanism is lifted by the crane to the top of the tank heating furnace flange, the fixed seat 1 overlaps with the heating furnace outlet flange, and then the crane is detached;

[0060] Positioning is achieved by inserting the movable end of the positioning cylinder 8 into the flange at the outlet of the heating furnace, and then the lifting cylinder 5 drives the boom 2 to move, thereby making the shaping mold 100 correspond to the position to be shaped.

[0061] Finally, the driving head 4 moves the shaping mold 100 to expand it, thereby pushing the tank wall to shape it.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
