Description

Technical Field

[0001] The utility model relates to the technical field of barrel bottom sealing heads, in particular to a convex sealing head structure for a barrel bottom. Background Art

[0002] With the continuous development of industrial technology, the performance requirements for storage containers are also constantly improving; especially in the chemical, petroleum, food and other industries, there are more stringent requirements for the strength, durability and sealing of the barrel bottom head structure;

[0003] Traditional barrel bottom designs usually adopt flat-plate or inward-concave head structures. Although the flat-plate head has a simple structure, it is particularly prone to deformation or damage when subjected to internal liquid pressure, affecting the service life and safety of the container. While the inward-concave head structure strengthens the barrel bottom to a certain extent, it is far from enough. This shape cannot disperse and withstand pressure well, so deformation or damage due to excessive pressure cannot be avoided. Its performance still needs to be improved. Utility Model Content

[0026] See also Figure 1 、 Figures 6-8 In an embodiment of the present invention, a convex head structure for a barrel bottom includes a head body 1, which gradually bulges downward from the outside to the inside;

[0027] The head body 1 is made by a stretching process. Different from the existing flat head or inward concave head, this outward convex head has high overall strength and is not easily deformed after bearing weight.

[0028] The outer edge of the head body 1 is in a flanged shape, and is rolled and attached to the outer lower end of the packaging steel drum 18.

[0029] exist Figures 1 to 4Middle: The inner side of the head body 1 is provided with multiple bearing mechanisms 2, and the bearing mechanisms 2 include a support seat 3. The left end of the support seat 3 is installed on the inner side of the head body 1, and support blocks 4 are installed on the front and rear surfaces of the left end of the support seat 3. The internal movable surface of the support block 4 is connected with multiple support bolts 5, and one end of the support bolt 5 is threadedly connected to the inner side of the head body 1. A bearing member 7 is provided at the right end of the support seat 3, and the bearing member 7 includes a bearing plate 8. The bearing plate 8 is a flanging structure, which is formed by hydraulic stretching technology. The prepared metal sheet is positioned on the workbench of the hydraulic stretching machine and fixed by a clamping device to ensure that the material does not move during the forming process. The hydraulic stretching equipment is started, and the metal sheet is stretched into a flanging structure at a specified position by controlling the hydraulic pressure and speed. The initial stretching pressure and speed are set according to the thickness of the steel plate and the forming requirements. 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, the pressure, speed and deformation are monitored in real time to ensure that the pore size is uniform and the shape is regular, and to avoid cracking or deformation caused by excessive stretching of the material, thereby avoiding the defects caused by the traditional welding process and ensuring the continuity and strength consistency of the structure. An elastic plate 9 is installed on the upper surface of the bearing plate 8, and the upper surface of the elastic plate 9 is movably fitted with the inner upper surface of the head body 1. The lower surface of the bearing plate 8 is rotatably connected to a threaded rod 10, which passes through and is threadedly connected to the right end of the support seat 3. The lower surface of the bearing plate 8 is located on the front and rear sides of the threaded rod 10. The slide rod 11 is movably installed on the support seat 3.

[0030] The bearing member 7 supports the upper end of the head body 1, further improving the anti-deformation function of the head body 1, thereby increasing the strength;

[0031] The lower end of the threaded rod 10 is hexagonal, and the threaded rod 10 can be rotated using a wrench, thereby driving the elastic plate 9 to rise and fall;

[0032] The material of the elastic plate 9 is preferably rubber.

[0033] exist Figure 2 and Figure 3 Middle: A reinforcing plate 6 is installed on the lower surface of the support base 3, and the left end of the reinforcing plate 6 is installed at the lower end position of the right surface of the support base 3;

[0034] The reinforcing plate 6 and the support base 3 form a triangular structure for improving the strength of the support base 3 .

[0035] exist Figures 1 to 5Middle: A gear 12 is installed at the outer lower end of the threaded rod 10, a positioning seat 13 is installed at the right end of the lower surface of the support seat 3, and a slide plate 14 is slidably connected to the interior of the positioning seat 13. A plurality of springs 15 are installed on the right surface of the slide plate 14, and the right end of the spring 15 is installed on the inner right surface of the positioning seat 13. A positioning plate 16 is installed on the left surface of the slide plate 14. The positioning plate 16 movably passes through the left surface of the positioning seat 13, and the left end of the positioning plate 16 movably is located between two adjacent teeth of the gear 12;

[0036] When the elastic plate 9 is in contact with the inner lower surface of the head body 1, the gear 12 is just opposite the positioning plate 16. At this time, the spring 15 is in an extended state, and the positioning plate 16 is stuck between two adjacent teeth of the gear 12 to fix the gear 12, preventing the threaded rod 10 from rotating and thus preventing it from displacing in the vertical direction, so that the elastic plate 9 is always in contact with the head body 1.

[0037] exist Figure 5 Middle: The lower surface of the slide plate 14 is mounted with a fixing rod 17;

[0038] The fixing rod 17 facilitates pushing the slide plate 14 to the right.

[0039] The working principle of the present utility model is as follows: the head body 1 is rolled onto the outside of the lower end of the packaging steel drum 18, and the support seat 3 is fixed to the inner side of the head body 1 through the support bolt 5. Then, one hand pulls the fixing rod 17 in the direction away from the threaded rod 10, driving the slide plate 14 to compress the spring 15, thereby driving the positioning plate 16 away from the threaded rod 10; the other hand clamps the lower end of the threaded rod 10 with a wrench and rotates the threaded rod 10. The threaded rod 10 drives the bearing plate 8 to rise, thereby driving the elastic plate 9 to fit closely with the inner lower surface of the head body 1. Then, the fixing rod 17 is released, the spring 15 will return to the extended state, and the positioning plate 16 will be stuck in the two adjacent teeth of the gear 12, thereby fixing the gear 12.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
