Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a can body shaping stamping die for iron can production. Background Technology

[0002] In the production process of iron cans (such as food cans, sealed cans, industrial cans, etc.), can shaping is a key process that determines the sealing and assembly properties of the product. It requires applying pressure to the can body through stamping dies to correct dimensions such as flange width, verticality, and roundness.

[0003] The specific principle of forming a can using a stamping die is to set the lower die as a contour die, with corresponding concave or convex structures. The shape of the upper die corresponds to that of the lower die. During operation, the operator places one end of the can onto the lower die. When the upper and lower dies close, the concave or convex structures are used to shape the can and perform operations such as flanging. However, during operation, the operator usually manually places one end of the can onto the lower die and applies downward force to ensure that the upper surface of the can is tightly against the lower die, while simultaneously stabilizing the can to prevent it from shaking during the stamping process. Relying solely on the operator to stabilize the can easily lead to wobbling during the stamping process, resulting in unsatisfactory shaping effects. Especially after long periods of work, operators are prone to fatigue or distraction, which further worsens the stability of the can's position during stamping, increasing the risk of workpiece damage and scrap, and causing a significant increase in production costs.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-3 A can body forming stamping die for iron can production includes a worktable (1), a lower die assembly (2), an upper die assembly (3), a power assembly (4), and a limiting assembly (5).

[0029] The lower mold assembly (2) includes a fixed platform (21) installed on one side of the worktable (1), and a lower mold head (22) is provided on one side of the fixed platform (21).

[0030] The workbench (1) is provided with a bracket (11), the power assembly (4) is installed on the bracket (11), the upper mold assembly (3) includes a fixing plate (31) installed on the power assembly (4), and the lower end of the fixing plate (31) is provided with an upper mold head (32) corresponding to the lower mold head (22).

[0031] The limiting component (5) includes a connecting frame (51) mounted on the fixed platform (21) and on the same side as the lower die head (22). There are two connecting frames (51) located on both sides of the lower die head (22). The connecting frame (51) is rotatably provided with limiting rollers (52).

[0032] Specifically, during the shaping and stamping of the can body, one end of the can body is fitted onto the lower die head 22, so that the upper end face of the can body is in close contact with the surface of the lower die head 22. Then, the upper die head 32 installed at the lower end of the fixing plate 31 is driven by the power component 4 to press down and close with the lower die head 22, and pressure is applied to the upper end face of the can body to complete the shaping of the can body. Then, the power component 4 drives the upper die head 32 to move up and reset. After the worker removes the can body from the lower die head 22, the can body is flipped over so that the other end of the can body is fitted onto the lower die head 22. Then, the other end of the can body is shaped to complete the shaping of the can body. The surface of the lower die head 22 has a concave structure required for shaping, and the shape of the upper die head 32 matches the shape of the lower die head 22. During stamping, the can body will conform to the shape of the lower die head 22 to complete the shaping.

[0033] During the process of the worker placing the can body onto the lower die head 22, the can walls on both sides of the can body will pass between the lower die head 22 and the limiting roller 52. After the can body is completely placed on the lower die head 22, the side can walls will be pressed by the limiting roller 52, so that the can walls are in close contact with the side of the lower die head 22 during this stamping and forming process. At the same time, the worker applies a downward pulling force to the can body, so that the upper end of the can body is in close contact with the upper surface of the lower die head 22, thereby preventing the can body from shaking during the stamping and forming process, improving the stability of the can body, which can not only improve the forming effect, but also reduce the occurrence of workpiece damage and scrap.

[0034] Based on the above embodiments, it is further proposed that the connecting frame (51) includes two connecting plates (53) and a mounting plate (54). The mounting plate (54) is fixedly connected to the fixed platform (21). The two connecting plates (53) are located on the upper and lower sides of the mounting plate (54) and extend in the same direction as the lower die head (22). The limiting roller (52) is located between the two connecting plates (53).

[0035] The limiting roller (52) has movable blocks (55) rotatably connected to both ends. The movable blocks (55) are guided and slidably disposed on the connecting plate (53). An elastic element (56) is disposed between the movable blocks (55) and the connecting plate (53). The elastic element (56) can apply a force to push the movable blocks (55) in the direction of the lower die head (22).

[0036] Specifically, when the tank wall passes between the side of the lower die head 22 and the limiting roller 52, the tank wall collides with the limiting roller 52. The limiting roller 52 is guided and slidably set on the connecting plate 53 by the movable block 55, which is rotatably connected, so that the limiting roller 52 moves outward while rotating under force. After the tank is completely fitted onto the lower die head 22, the elastic element 56 applies a pushing force to the movable block 55, so that the limiting roller 52 can continuously press against the tank wall, so that the pipe wall is always in close contact with the side of the lower die head 22, further enhancing the overall stability of the tank.

[0037] The limiting roller 52 is rotatably connected to the movable block 55 at both ends, which allows the limiting roller 52 to move while rotating as the tank wall goes deeper, making it easier for the tank wall to go deeper and reducing friction with the tank wall to avoid damage to the tank wall.

[0038] Based on the above embodiments, it is further proposed that the connecting plate (53) is provided with a movable groove (57), the movable block (55) is guided and disposed inside the movable groove (57), and the elastic element (56) is disposed between the movable block (55) and the movable groove (57);

[0039] A limiting plate (58) is provided on the movable block (55), and the limiting plate (58) is located on the side of the connecting plate (53) away from the limiting roller (52).

[0040] Specifically, the movable block 55 is guided and positioned in the movable groove 57 opened on the connecting plate 53, and the elastic element 56 is positioned between the movable block 55 and the movable groove 57, so that the trajectory of the movable block 55 is stable when it moves in translation, that is, the limiting roller 52 can move in a stable manner. A limiting plate 58 is set on the movable block 55 to limit it and prevent it from falling out of the movable groove 57. The elastic element 56 is preferably a spring.

[0041] Based on the above embodiments, it is further proposed that a slider (59) is provided on the limiting plate (58), and a slide rail (510) corresponding to the slider (59) is provided on the connecting plate (53), and the slider (59) and the slide rail (510) slide together.

[0042] Specifically, the sliding cooperation between slider 59 and slide rail 510 makes the translation of limit plate 58 smoother.

[0043] Based on the above embodiments, it is further proposed that both ends of the limiting roller (52) are connected to a rotating shaft (511), and a bearing (512) is provided on the movable block (55). The rotating shaft (511) and the bearing (512) are rotatably connected to achieve the rotatable connection between the limiting roller (52) and the movable block (55).

[0044] Based on the above embodiments, it is further proposed that the surface of the limiting roller (52) is covered with a soft rubber sleeve (513).

[0045] Specifically, the soft rubber sleeve 513 can be made of materials such as silicone or rubber. The soft rubber sleeve 513 can reduce the hard impact and friction on the surface of the can, thus avoiding surface damage.

[0046] Furthermore, the power assembly (4) includes a hydraulic cylinder (41) mounted on the bracket (11) and a lifting block (42) that can slide up and down on one side of the bracket (11). The telescopic shaft of the hydraulic cylinder (41) is fixedly connected to the lifting block (42), and the fixing plate (31) is fixedly mounted on one side of the lifting block (42). The lifting block (42) is driven to move up and down by the hydraulic cylinder (41), thereby driving the fixing plate (31) and the upper mold head (32) to move up and down, so as to realize the mold closing and mold opening with the lower mold head (22).

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
