[0002] During industrial production, various tanks are prone to deformation due to factors such as high temperature and their own weight. In order to ensure the normal application and safety of the tanks, it is necessary to use a shaping mechanism to shape them to prevent the deformation of the tanks from affecting their working performance.

[0003] An existing invention patent with authorization announcement number CN109000152B discloses a container shaping device.

The shaping mechanism includes a hydraulic cylinder and a pair of pressure arms. The hydraulic cylinder is mounted on a support rod, and the pair of pressure arms are symmetrically arranged on the push rod of the hydraulic cylinder. The outer end of each pressure arm is provided with a pressure plate, which is used to contact a mounting plate.

[0004] In the above scheme, the adjacent hoop assembly is driven by a hydraulic cylinder to squeeze the tank body, thereby achieving tank body shaping. However, this squeezing and shaping method is difficult to correct the shape of the tank body, and has low controllability and precision, so it urgently needs to be improved. Utility Model Content

[0031] 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.

[0032] like Figures 1-2 As shown, the shaping mechanism of this utility model includes a wedge block 1, a mold 2, a pyramid 3, a pull rod 4, a worktable 5, a cover 6, a sleeve 7, and a piston rod 8.

[0033] like Figure 1 As shown, multiple wedges 1 are arranged in a circular array, and the sides of the wedges 1 abut against each other; the mold 2 is set on the outer end face of the multiple wedges 1; the pyramid 3 abuts against the inner end face of the wedges 1; the pull rod 4 is connected to the pyramid 3;

[0034] As described above, in application, the shaping mechanism is placed inside the tank to be shaped. Then, the linear module drives the pull rod 4 to move, which in turn drives the pyramid 3 to move. The pyramid 3 pushes the wedge 1, which in turn drives the mold 2 to push the inner wall of the tank, achieving an expansion effect. In this way, the tank can be shaped.

[0035] Compared with the extrusion shaping method used in existing tank shaping mechanisms, it has the advantages of high controllability and good shaping effect.

[0036] Specifically, linear modules can use linear displacement components such as cylinders, hydraulic cylinders, or electric push rods.

[0037] Specifically, pyramid 3 can adopt a structure with a large top and a small bottom, or a structure with a small top and a large bottom, depending on the specific application scenario.

[0038] like Figure 1 As shown, wedge 1 is inserted into workbench 5, and pyramid 3 penetrates workbench 5;

[0039] As described above, by setting up a workbench 5 and inserting the wedge 1 into the workbench 5, a guiding effect can be achieved, ensuring the stable movement of the wedge, so that the mold 2 can accurately shape the part of the tank to be shaped, and it is also convenient to disassemble and replace the wedge 1 and the mold 2.

[0040] Specifically, the workbench 5 is fixed relative to the linear module that moves with the pull rod 4.

[0041] like Figure 1 As shown, the thickness of the wedge 1 is set in a stepped shape, and the thickness of the end of the wedge 1 that connects to the mold 2 is greater than the thickness of the end that abuts against the pyramid 3.

[0042] As described above, the thickness of the wedge 1 is arranged in a stepped manner, and the thickness of the end that abuts against the pyramid 3 is smaller, thus reducing the machining surface and improving the convenience of machining.

[0043] like Figure 1 As shown, the cover 6 is installed on the bottom surface of the workbench 5;

[0044] As described above, by providing the cover 6, the worktable 5 and the wedge 1 can be protected, thereby preventing foreign objects from entering. This reduces the relative wear between the wedge 1 and the worktable 5, thus ensuring the service life.

[0045] like Figure 1 As shown, the sleeve 7 is disposed on the bottom surface of the cover 6, the sleeve 7 is connected to the cover 6, and corresponds to the pyramid 3;

[0046] As described above, by setting up the sleeve 7, which works in conjunction with the cover 6 to ensure good protection while leaving room for the pyramid 3 to move, so that the pyramid 3 can drive the wedge block 1 and the mold 2 to move.

[0047] like Figure 1 As shown, one end of the pyramid 3 is inserted into the piston rod 8; the pull rod 4 passes through the pyramid 3 and is connected to the piston rod 8;

[0048] As described above, the pyramid 3 is connected to the piston rod 8 and fixed by the pull rod 4. The linear module uses a hydraulic cylinder, and the piston rod 8 is the moving part of the hydraulic cylinder. In this way, the pyramid 3 can be moved to perform shaping work through the mold 2. In this structure, the pyramid 3 can be removed from the piston rod 8 by disassembling the pull rod 4, which has the advantage of convenient disassembly and maintenance.

[0049] In the illustrated structure, the pyramid 3 adopts a structure with a large upper end and a small lower end. In actual application, the sleeve 7 can be set as a detachable structure, and the pyramid 3 can adopt a structure with a small upper end and a small lower end. After removing the sleeve 7, the pyramid 3 can be lowered through the straight module, and the tie rod 4 and the pyramid 3 can be removed from the bottom, thereby improving the convenience of disassembly and maintenance.

[0050] like Figure 1 As shown, the reset mechanism 9 is installed inside the worktable 5 and is used to drive multiple wedges 1 to move closer together.

[0051] As described above, the reset mechanism 9 is used to drive the wedge block 1 and the mold 2 to move, so that after the wedge block 1 and the mold 2 expand, they can be retracted and reset.

[0052] Specifically, the reset mechanism 9 is one of a cylinder, a hydraulic cylinder, or a tension spring.

[0053] The tank shaping machine of this utility model includes the above-mentioned shaping mechanism.

[0054] Furthermore, the tank shaping machine also includes a rotating mechanism, which is used to drive the shaping mechanism to rotate;

[0055] like Figure 2 As shown, after the mold 2 expands, there will be gaps between the molds 2. By rotating the forming mechanism, the corresponding positions of the molds 2 can be adjusted to form the parts in the gaps that have not been pushed and shaped, thus ensuring the comprehensiveness of the forming.

[0056] Specific implementation steps:

[0057] First, the shaping mechanism is inserted into the tank. Then, the piston rod 8 is moved by the linear module. The piston rod 8 will then move the pyramid 3. The pyramid 3 pushes the wedge 1 and the mold 2, which in turn pushes the inner wall of the tank to shape it.

[0058] After one shaping is completed, the linear module drives the pyramid 3 to reset via the piston rod 8. At the same time, the reset mechanism 9 drives the wedge block 1 and the mold 2 to reset. Then, the rotating mechanism drives the shaping mechanism to rotate to adjust the angle, and the above displacement action of the wedge block 1 and the mold 2 is repeated for reshaping.

[0059] 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.
