[0027] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0028] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. Example

[0029] like Figure 1-10As shown, the utility model provides a double-bone buckle device for a can body, comprising a base 1, a frame 2 installed on the base 1, a platform 3 arranged on the frame 2 and a power component 4, the power component 4 is provided with a pressure plate 5 for pressing the mold or a downward stretching component, the platform 3 is provided with a first mold 6 for "Z"-shaped bending, a second mold 7 for limited alignment, a third mold 8 for flattening and "V"-shaped bending and a fourth mold 9 for "V"-shaped bending, the first mold 6 and the second mold 7 are arranged in a group opposite to each other, the third mold 8 and the fourth mold 9 are arranged in a group opposite to each other, the first mold 6 and the second mold 7 simultaneously bend the two sides of the metal sheet of the can body, and after bending, they are sent into the third mold 8 and the fourth mold 9 to bend the two sides of the metal sheet of the can body at the same time.

[0030] Through the integrated design, that is, the first mold 6 and the second mold 7 are arranged in a group relative to each other, and the third mold 8 and the fourth mold 9 are arranged in a group relative to each other, the synchronous bending processing of the two sides of the metal sheet of the can body is achieved. The parallel processing method significantly shortens the production cycle of a single can body and improves the overall production efficiency.

[0031] Pressing the pressing plate 5 of the mold or stretching the component downwards, both ways of applying pressure improve environmental adaptability.

[0032] Each mold is precisely designed and manufactured to ensure accurate Z-bending, position alignment, flattening, and V-bending of the can body metal sheet. These bending operations complete the double buckle structure.

[0033] See also Figure 4 、 Figure 5 and Figure 6 The first mold 6 is provided with a first movable block 61 and a first fixed block 62 of a "Z"-shaped cutter head. A first transverse block 64 and a first transmission pin 63 are provided above the first movable block 61. The first transmission pin 63 moves downward to push the first transverse block 64 to separate the two sides. The oblique side of the first transverse block 64 slides on the oblique side above the first movable block 61 to drive the first movable block 61 to move downward to complete the downward pressing action. A second transverse block 66 is provided behind the first movable block 61. The first transmission pin 63 moves downward to push the second transverse block 66 to separate the two sides. The oblique side of the second transverse block 66 slides on the oblique side behind the first movable block 61 to drive the first movable block 61 to move forward to complete the forward pressing action, and finally completes the "Z"-shaped bending of the can body metal sheet.

[0034] Through the precise cooperation of the first movable block 61 and the first fixed block 62 of the "Z"-shaped cutter head, and the coordinated action of the first transverse block 64 and the second transverse block 66, precise "Z"-shaped bending of the can body metal sheet is achieved.

[0035] The “Z”-bend design increases the thickness and complexity of the tank’s sidewalls, thereby improving the tank’s structural strength.

[0036] See also Figure 4 The second die 7 is provided with a limit block 71. The limit block 71, with its precise size and position design, provides a fixed reference point for the can body metal sheet. During the processing, the can body metal sheet needs to be accurately placed between the limit blocks 71 to ensure that the subsequent bending or forming operations can be carried out at the predetermined position and angle.

[0037] During the processing, due to the influence of mechanical vibration, material elasticity and other factors, the metal sheet of the can body may be slightly offset. The presence of the limit block 71 can effectively prevent such offset and ensure that the metal sheet of the can body always remains in the correct position.

[0038] See also Figure 7 、 Figure 8 、 Figure 9 and Figure 10 The third mold 8 is provided with a second movable block 81 and a third movable block 82 with a "V"-shaped cutter head. A third transverse block 84 and a second transmission pin 83 are provided above the second movable block 81. The second transmission pin 83 moves downward to push the third transverse block 84 to separate the two sides. The oblique side of the third transverse block 84 slides on the oblique side above the second movable block 81 to drive the second movable block 81 to move downward to complete the downward pressing action. A fourth transverse block 86 is provided behind the third movable block 82. The second transmission pin 83 moves downward to push the fourth transverse block 86 to separate the two sides. The oblique side of the fourth transverse block 86 slides on the oblique side behind the third movable block 82 to drive the third movable block 82 to move forward to complete the forward pressing action, and finally completes the "V"-shaped bending of the can body metal sheet.

[0039] Through the precise cooperation of the second movable block 81 and the third movable block 82 of the "V"-shaped cutter head, and the coordinated action of the third transverse block 84 and the fourth transverse block 86, a precise "V"-shaped bending of the can body metal sheet is achieved.

[0040] This design reduces the complexity and time cost of manual operation and improves production efficiency. At the same time, the precise bending process also reduces the scrap rate, further improving production benefits.

[0041] Through the integrated mold design, multiple bending steps of the can metal sheet can be completed continuously in the same set of equipment, thereby simplifying the production process and improving production efficiency and flexibility.

[0042] See also Figure 7 、 Figure 8 、 Figure 9 and Figure 10The fourth mold 9 is provided with a fourth movable block 91 with a "V"-shaped cutter head and a second fixed block 92. A fifth transverse block 94 and a third transmission pin 93 are provided above the fourth movable block 91. The third transmission pin 93 moves downward to push the fifth transverse block 94 to separate the two sides. The oblique side of the fifth transverse block 94 slides on the oblique side above the fourth movable block 91 to drive the fourth movable block 91 to move downward to complete the downward pressing action. A sixth transverse block 96 is provided behind the fourth movable block 91. The third transmission pin 93 moves downward to push the sixth transverse block 96 to separate the two sides. The oblique side of the sixth transverse block 96 slides on the oblique side behind the fourth movable block 91 to drive the fourth movable block 91 to move forward to complete the forward pressing action, and finally completes the "V"-shaped bending of the can body metal sheet.

[0043] The design of the fourth die 9 enables the can body metal sheet to complete the final "V"-shaped bending here after the previous processing steps.

[0044] Through precise mechanical structure and control mechanism, the fourth die 9 can ensure the consistency and accuracy of each bend.

[0045] The V-bend design helps increase the rigidity and stability of the can's sidewalls. When the two opposing V-bends are completed, they work together to strengthen the can's overall structural strength, enabling it to better withstand internal pressure or external impact.

[0046] Similar to the aforementioned molds, the fourth mold 9 also adopts an automated and mechanized design, which reduces the complexity and time cost of manual operation and improves production efficiency. The precise bending process also reduces the scrap rate, further improving production efficiency.

[0047] Among them, the metal sheets of the can body are transferred between the two sets of molds through reciprocating iron plates with hooks.

[0048] The iron plate with hooks moves back and forth between the two sets of molds, which can automatically transfer the can body metal sheets from one set of molds to the other set of molds for the next processing, reducing the need for manual handling and significantly improving production efficiency. Manual handling may cause damage or position displacement of the can body metal sheets due to improper operation, while automated transfer greatly reduces this risk and improves processing accuracy.

[0049] By transferring through an iron plate with hooks, the two sets of molds can be made more compact in layout, saving production space.

[0050] Among them, the double-bone structure of the tank body increases the strength and rigidity of the tank body, enabling it to withstand greater internal pressure and external impact. It also helps to form tighter seams and edges, thereby improving the sealing performance of the tank body.
