Technical Field

[0001] This utility model relates to the field of can manufacturing technology, specifically to a deformation-resistant support structure for can body forming. Background Technology

[0002] Can manufacturing refers to the production process of turning metal or non-metal materials into metal or composite cans for holding food, beverages, chemicals, aerosols, and other products through a series of processing techniques. It is an important branch of the packaging industry, with metal can production being the most typical and mature.

[0003] Currently, irregularly shaped cans are usually processed by mold pressure molding. During the molding process, the can body is fitted onto the outside of the moving mold and the stationary mold, and the movement of the moving mold is used to expand and shape the can body. This molding method is prone to incomplete shaping at the edges and corners of the irregularly shaped can body, which can easily lead to subsequent deformation. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a deformation-resistant support structure for can body forming, so as to solve the problem of poor edge and corner forming effect and easy deformation in the processing of irregular can bodies mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant support structure for can body forming, comprising a workbench, a fixed mold fixedly connected to the workbench, a movable mold movably connected to one side of the fixed mold, a can body fitted onto the outer walls of the movable mold and the fixed mold, limiting mold corners provided at the four corners of the can body, positioning templates provided on the four sides of the can body, an opening provided on the inner side of the limiting mold corner, an intercepting net provided inside the opening, a collection pipe connected to one end of the limiting mold corner, and a negative pressure pump connected to one end of the collection pipe.

[0006] Preferably, the top of the workbench is provided with multiple sliding grooves, one end of which is fixedly connected to a first hydraulic cylinder, a limiting mold corner is inserted inside the sliding groove, one end of the first hydraulic cylinder is connected to the limiting mold corner, and the first hydraulic cylinder and the workbench form a sliding connection.

[0007] Preferably, a second hydraulic cylinder is embedded inside the fixed mold, and one end of the second hydraulic cylinder is connected to the movable mold.

[0008] Preferably, both ends of the fixed mold are provided with grooves, and a limiting rod is inserted into the groove, with one end of the limiting rod being fixedly connected to the movable mold.

[0009] Preferably, the limiting rods are symmetrically distributed about the bisector of the movable mold, and the limiting rods and the fixed mold are slidably connected.

[0010] Preferably, a negative pressure pump is fixedly connected to the top of the workbench, and the air inlet of the negative pressure pump is connected to a main pipe, on which a solenoid valve is installed.

[0011] Preferably, one end of the main pipe is connected to a manifold, and the manifold is provided with multiple branch pipes, which are respectively connected to multiple limiting mold angles.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This device can not only achieve rapid forming of the tank, but also ensure that the edges and corners of the tank are formed in place, thereby avoiding the subsequent deformation of the edges and corners of the tank due to incomplete forming.

[0014] (2) This device sets multiple limiting mold corners on the top of the workbench, located at the four corners of the tank. It can not only limit the outside of the tank during the tank forming process, but also use the negative pressure of the manifold to make the tank come into contact with the limiting mold corners. After contact, the tank is quickly adsorbed by the negative pressure to make the tank adhere tightly to the limiting mold corners, avoiding gaps between the tank and the limiting mold corners, improving the forming quality of the tank and avoiding subsequent deformation of the tank.

[0015] (3) This device can limit the movement of the movable mold by setting a limit rod, making the movement of the movable mold more stable and ensuring the processing quality of the tank by the movable mold. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-3This utility model provides a technical solution: a deformation-resistant support structure for can body forming, including a workbench 4, on which a fixed mold 9 is fixedly connected. Multiple sliding grooves are formed at the top of the workbench 4, and a first hydraulic cylinder 1 is fixedly connected to one end of each groove. A limiting mold angle 2 is inserted inside the groove. One end of the first hydraulic cylinder 1 is connected to the limiting mold angle 2, and the first hydraulic cylinder 1 and the workbench 4 form a sliding connection. This structure, through the limiting mold angle 2, can assist in the forming of the outer side of the can body 12, while the first hydraulic cylinder 1 can adjust the position of the limiting mold angle 2 to ensure that the limiting mold angle 2 is in a suitable position, and the fixed mold... A second hydraulic cylinder 14 is embedded inside the fixed mold 9. One end of the second hydraulic cylinder 14 is connected to the movable mold 10. This structure allows the movable mold 10 to move automatically via the second hydraulic cylinder 14, supporting one end of the tank body 12 and enabling rapid forming of the tank body 12. Both ends of the fixed mold 9 have grooves, and limiting rods 11 are inserted into the grooves. One end of the limiting rod 11 is fixedly connected to the movable mold 10. The limiting rods 11 are symmetrically distributed about the bisector of the movable mold 10, and the limiting rods 11 and the fixed mold 9 form a sliding connection. This structure allows the movable mold 10 to move via the limiting rods 11. Limiting the movement of the movable mold 10 ensures its stability and guarantees the effective forming of the limiting mold corner 2. A negative pressure pump 6 is fixedly connected to the top of the workbench 4. The air inlet of the negative pressure pump 6 is connected to a main pipe 7, which is equipped with a solenoid valve 5. This structure allows for adjustment of the suction force via the solenoid valve 5. One end of the main pipe 7 is connected to a manifold 8, which has multiple branch pipes connected to multiple limiting mold corners 2. This structure enables the multiple limiting mold corners 2 to have negative pressure adsorption capabilities, facilitating the tight fit between the tank 12 and the inner wall of the limiting mold corner 2 using negative pressure adsorption. A movable mold 9 is movably connected to one side of the fixed mold 9. Mold 10, movable mold 10 and fixed mold 9 are fitted with a tank body 12 on their outer walls. Each of the four corners of the tank body 12 is provided with a limiting mold corner 2. Each of the four sides of the tank body 12 is provided with a positioning template 3. An opening is opened on the inner side of the limiting mold corner 2. An intercepting net 13 is provided inside the opening. One end of the limiting mold corner 2 is connected to a manifold 8. One end of the manifold 8 is connected to a negative pressure pump 6. The negative pressure pump 6 can generate suction force on the limiting mold corner 2, so that the tank body 12 can fit tightly against the inner wall of the limiting mold corner 2. The intercepting net 13 can play a supporting and intercepting role when the tank body 12 contacts the limiting mold corner 2, so as to avoid deformation caused by excessive suction force.

[0022] Working principle: When using this anti-deformation support structure for can body forming, firstly, the can body 12 to be formed is fitted onto the outer wall of the fixed mold 9 and the movable mold 10, so that one end of the can body 12 is inserted between the fixed mold 9 and the limiting mold corner 2. Then, the second hydraulic cylinder 14 pushes the movable mold 10 to move. During the movement, the movable mold 10 pushes the can body 12 closer to the other end limiting mold corner 2, so that the can body 12 is opened up and the four sides of the can body 12 are attached to the inner wall of the positioning template 3. At the same time, under the action of the negative pressure pump 6, the can body 12 is tightly attached to the inner wall of the limiting mold corner 2, completing the forming work. After the can body 12 is formed, the movable mold 10 is reset, the negative pressure pump 6 is turned off, and finally the can body 12 can be taken out.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
