[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] With the reinforcing ring and reinforcing strips, the present utility model can ensure the strength of the cylindrical supporting bottom plate, so that when the liquid in the packaging barrel presses the cylindrical supporting bottom plate, the cylindrical supporting bottom plate is not easily deformed. By means of the two strip-shaped openings, both the curling plate and the first sealing groove are divided into two parts. Therefore, when the curling plate is curled on the bottom of the packaging barrel by the curling plate equipment, the curling plate will not be damaged, ensuring the processing quality. By embedding two sealing strips in the corresponding first sealing grooves, and each first sealing groove straddles a strip-shaped opening, the sealing performance at the strip-shaped opening is ensured, so that the joint between the curling plate and the packaging barrel is not prone to leakage; by embedding two sealing rings in the corresponding second sealing grooves, the sealing performance at the joint between the cylindrical supporting bottom plate and the packaging barrel is ensured, further improving the sealing effect.

Detailed Embodiment
[0019] Please refer to Figures 1 to 5, in the embodiment of the present utility model, a concave head structure for the bottom of a barrel includes a cylindrical support bottom plate 1. At the lower end of the outer side of the cylindrical support bottom plate 1, a curled edge plate 5 is fixedly connected. Two sealing strips 6 are embedded in the curled edge plate 5, and two sealing rings 7 are embedded in the cylindrical support bottom plate 1. And on the upper side of the cylindrical support bottom plate 1, there is a five-pointed star-shaped groove 8 that is concave into the bottom of the packaging barrel 11. The five-pointed star shape is set to increase the strength of the barrel bottom and is simple and beautiful. The five-pointed star-shaped groove 8 is made by hydraulic stretching technology. Position the prepared metal sheet on the workbench of the hydraulic stretching machine and fix it through the clamping device to ensure that the material does not move during the forming process. Start the hydraulic stretching equipment, and by controlling the hydraulic pressure and speed, stretch the metal sheet into the required shape at the specified position. According to the thickness of the steel plate and the forming requirements, set the initial stretching pressure and speed. The pressure is generally in the range of 50 to 200 MPa, and the stretching speed is controlled at 0.1 to 10 mm / s. During the stretching process, monitor the pressure, speed, and deformation amount in real time to ensure that the hole diameter is uniform, the shape is regular, and avoid rupture or deformation caused by excessive stretching of the material. Inside the cylindrical support bottom plate 1, there is a group of reinforcing rings 9, and several reinforcing bars 10 are arranged between the group of reinforcing rings 9. The strength of the cylindrical support bottom plate 1 is ensured by the reinforcing rings 9 and the reinforcing bars 10, so that when the liquid in the packaging barrel 11 presses the cylindrical support bottom plate 1, the cylindrical support bottom plate 1 is not easily deformed.
[0020] In Figure 1 , Figure 2 and Figure 3 , the cylindrical support bottom plate 1 and the curled edge plate 5 are an integrally formed structure by stretching, so as to ensure that the raw material does not become thinner and has a uniform thickness during stretching, ensuring the strength.
[0021] In Figure 1 , Figure 2 and Figure 3 , on the upper side of the curled edge plate 5, away from the outer side of the cylindrical support bottom plate 1, a first sealing groove 2 is provided, and two strip-shaped openings 3 are provided on the outer side of the curled edge plate 5. The curled edge plate 5 and the first sealing groove 2 are both divided into two parts by the two strip-shaped openings 3. Thus, when the curled edge plate 5 is curled on the bottom of the packaging barrel 11 through the curling edge plate equipment, the curled edge plate 5 is not damaged, ensuring the processing quality.
[0022] In Figure 3 , Figure 4 and Figure 5 , two sealing strips 6 are embedded in the corresponding first sealing grooves 2, and each first sealing groove 2 straddles a strip-shaped opening 3, so as to ensure the sealing performance at the strip-shaped opening 3, making it not easy for the joint between the curled edge plate 5 and the packaging barrel 11 to leak.
[0023] In Figure 3 , Figure 4 andFigure 5 In it, a set of second sealing grooves 4 are formed on the outer side of the cylindrical support bottom plate 1, and two sealing rings 7 are embedded in the corresponding second sealing grooves 4, thereby ensuring the sealing performance at the junction of the cylindrical support bottom plate 1 and the packaging barrel 11.
[0024] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
