Description

Technical Field

[0001] The utility model relates to the technical field of ammunition assembly, and more specifically, it relates to a simple press structure for pressing and closing the mouth of a shell. Background Art

[0002] A shell is ammunition with a caliber above 20 mm, which realizes tactical purposes by means of artillery firing. It consists of multiple parts such as a fuse, a primer, a cartridge case, and a projectile body. During the assembly process of the shell, the mouth-closing process is the last step. In this step, a mouth-closing device is used to tightly combine the projectile body with the cartridge case to ensure that the shell can reach the expected ballistic target.

[0003] In the patent with the publication number CN220818754U, a dual-purpose horizontal mouth-closing device for small-caliber ammunition is disclosed, which includes a main body. A fixing component is arranged on the top of the main body. The fixing component includes a bottom plate, which is fixedly installed on the top of the main body. A fixing frame is fixedly installed on the top of the bottom plate. An electric telescopic rod is fixedly installed inside the fixing frame. The bottom end of the electric telescopic rod is fixedly installed with an electric clamp, and one side of the electric clamp is fixedly connected with a connecting wire.

[0004] The mouth-closing device in the above solution can prevent the projectile body of the ammunition from shifting during mouth-closing, and can effectively improve the stability of the hydraulic rod, thereby improving the production quality of the ammunition.

[0005] Although this mouth-closing device can improve the production quality of ammunition to a certain extent, its operation highly depends on a stable power supply. Once special situations such as power outage or power failure occur, the device cannot work normally, which will lead to a decline in production efficiency.

[0006] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0007] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a simple press structure for pressing and closing the mouth of a shell, which can replace the gas cylinder as the power source in case of special situations such as power outage or power failure, ensure the continuous production, and avoid a significant decline in production efficiency.

[0008] The above technical purpose of the utility model is achieved through the following technical solutions: The simple press structure for pressing and closing the mouth of a shell includes a placement table. A through groove is opened on the placement table. A stabilizing frame is fixedly connected to the bottom side of the placement table. A gas cylinder is slidably connected in the through groove. A fixing frame is fixedly connected to the placement table. A mouth-closing component is fixedly connected to the fixing frame and the placement table.

[0009] The present utility model is further configured as follows: The tightening component includes a lower pressing block fixedly connected to the placement table, an air cylinder fixedly connected to the fixing frame, a piston rod slidably connected within the air cylinder, and an upper pressing block fixedly connected to one end of the piston rod close to the lower pressing block. A tension spring is fixedly connected between the top side inside the air cylinder and the piston rod. A hose is threadedly connected to the upper side of the air cylinder, and the other end of the hose is fixedly connected to the air outlet of the gas cylinder. The air cylinder, the hose, and the gas cylinder are in mutual communication. When the upper pressing block is in contact with the lower pressing block, the tension spring is in a stretched state. A through hole is formed in the air cylinder.

[0010] The present utility model is further configured as follows: A lower stabilizing block is connected to the placement table. Spring telescopic rods are fixedly connected to both sides of the lower stabilizing block. The other ends of both spring telescopic rods are fixedly connected to fixing blocks. An upper stabilizing block is fixedly connected between the two fixing blocks.

[0024] The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] A simple press structure for shell pressing and closing, as Figures 1 - 6 shown, includes a placing table 1, a through groove 2 is opened on the placing table 1, a stabilizing frame 3 is fixedly connected to the bottom side of the placing table 1, a gas cylinder 4 is slidably connected in the through groove 2, a fixed frame 5 is fixedly connected to the placing table 1, and a closing assembly is fixedly connected to the fixed frame 5 and the placing table 1. The closing assembly includes a lower pressing block 6 fixedly connected to the placing table 1, an air cylinder 7 fixedly connected to the fixed frame 5, a piston rod 8 slidably connected in the air cylinder 7, and an upper pressing block 9 fixedly connected to one end of the piston rod 8 close to the lower pressing block 6. A tensile spring 10 is fixedly connected between the top side of the air cylinder 7 and the piston rod 8. A hose 11 is threadedly connected to the upper side of the air cylinder 7, and the other end of the hose 11 is fixedly connected to the air outlet of the gas cylinder 4. The air cylinder 7, the hose 11, and the gas cylinder 4 are in mutual communication. When the upper pressing block 9 is in contact with the lower pressing block 6, the tensile spring 10 is in a stretched state, and a through hole 71 is opened on the air cylinder 7.

[0026] As Figures 1 - 6As shown in the figure, in the event of special situations such as power outages or power cuts, the air pump originally thread - connected to the air cylinder 7 can be removed first. Then, the air cylinder 7, the hose 11, and the gas cylinder 4 are connected. After that, a shell is placed and the switch of the gas cylinder 4 is turned, opening the gas cylinder 4. The gas in the gas cylinder 4 enters the air cylinder 7 through the hose 11. At this time, most of the gas will push the piston rod 8 downward, and a small part of the gas will overflow from the through - hole 71 on the air cylinder 7. And at this time, the tension spring 10 is in a stretched state. When the piston rod 8 moves downward, it will drive the upper pressing block 9 downward to cooperate with the lower pressing block 6 to perform the operation of tightening the mouth of the shell. After the mouth - tightening is completed, the gas cylinder 4 is closed. At this time, the piston rod 8 is no longer pushed by the gas, and the tension spring 10 starts to reset to the normal state. The gas in the air cylinder 7 overflows from the through - hole 71 to the outside, and the upper pressing block 9 also starts to rise and reset. In this way, when there is a power cut or power outage, the gas cylinder 4 can be replaced as the power source to ensure the continuous progress of production and avoid a significant decline in production efficiency.

[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown in the figure, a lower stabilizing block 12 is connected to the placement table 1. Spring telescopic rods 13 are fixedly connected to both sides of the lower stabilizing block 12. The other ends of the two spring telescopic rods 13 are both fixedly connected to fixing blocks 14. An upper stabilizing block 15 is fixedly connected between the two fixing blocks 14. When the upper stabilizing block 15 is in contact with the lower stabilizing block 12, the spring telescopic rods 13 are in the normal state. Positioning rods 16 are fixedly connected to both sides of the upper pressing block 9. The positioning rods 16 are in contact with the lower sides of the fixing blocks 14. When the upper pressing block 9 descends, it will drive the positioning rods 16 to descend. Then, as the positioning rods 16 descend, the spring telescopic rods 13 start to contract. When contracting, they will drive the upper stabilizing block 15 to descend and fit with the lower stabilizing block 12. In this way, the shell can be stabilized before mouth - tightening to avoid the shell moving during mouth - tightening, resulting in a decline in production quality. When the upper pressing block 9 resets, it will drive the positioning rods 16 to rise and lift the upper stabilizing block 15 to facilitate the next shell stabilization.

[0028] As Figures 1 - 3As shown, the lower stabilizing block 12 is slidably connected to the placing table 1. An extension rod 17 is fixedly connected to the positioning rod 16 on one side close to the fixing frame 5. Only setting the extension rod 17 on one side can facilitate the removal of the shell on the other side. When the lower stabilizing block 12 slides, the extension rod 17 contacts the fixing block 14 on the same side. After the mouth tightening is completed and the upper pressing block 9 is lifted, the lower stabilizing block 12 can be moved to slide on the placing table 1. At this time, the upper stabilizing block 15 is also driven by the lower stabilizing block 12 and starts to move away from the gas cylinder 4. And at this time, the fixing block 14 will move on the inclined surface of the extension rod 17. When the lower stabilizing block 12 moves to the farthest position from the gas cylinder 4, the upper stabilizing block 15 will fit with the lower stabilizing block 12. At this time, it is more convenient to remove the shell. When removing the assembled shell and putting in a new shell, the lower stabilizing block 12 can be moved towards the gas cylinder 4 side, and the fixing block 14 will move on the inclined surface of the extension rod 17, thereby driving the upper stabilizing block 15 to move upward until the upper stabilizing block 15 is on the upper side of the lower stabilizing block 12. Then the next mouth tightening operation can be carried out.

[0029] As Figure 5 shown, the lower side of the fixing block 14 is inclined, which can make the fixing block 14 move more smoothly and without jamming on the extension rod 17.

[0030] As Figure 1 , Figure 3 , Figure 6 shown, a lifting frame 18 is slidably connected between the lower stabilizing block 12 and the lower pressing block 6. A sliding rod 19 is slidably connected between the gas cylinder 4 and the lower pressing block 6. The sliding rod 19 and the lifting frame 18 are fixedly connected by a connecting rod 20. A trigger frame 21 is fixedly connected to the sliding rod 19. The trigger frame 21 is on the upper side of the upper pressing block 9. A positioning plate 22 is fixedly connected to the sliding rod 19. When putting in the shell, the shell can be first placed on the lifting frame 18 and the bottom end of the shell contacts the positioning plate 22. Then when the upper pressing block 9 descends, the lifting frame 18 will move downward due to the gravity of the shell, so that the shell can be in a suitable mouth tightening position. After the mouth tightening is completed, as the upper pressing block 9 rises, the upper pressing block 9 will contact the trigger frame 21 and drive the trigger frame 21 to move upward, thereby driving the lifting frame 18 to lift the shell to facilitate the removal of the shell.

[0031] Working principle: In the event of special situations such as power outages or power cuts, first remove the air pump that was originally threadedly connected to the air cylinder 7, then connect the air cylinder 7, the hose 11, and the gas cylinder 4 together. Next, place the shell on the supporting frame 18 and make the bottom end of the shell contact the positioning plate 22. Then move the lower stabilizing block 12 towards the side of the gas cylinder 4. At this time, the fixed block 14 will move on the inclined surface of the extension rod 17, thereby driving the upper stabilizing block 15 to move upward until the upper stabilizing block 15 is on the upper side of the lower stabilizing block 12. Then turn the switch of the gas cylinder 4 to open the gas cylinder 4, so that the gas in the gas cylinder 4 enters the air cylinder 7 through the hose 11. At this time, most of the gas will push the piston rod 8 downward, and a small part of the gas will overflow from the through hole 71 on the air cylinder 7. At this time, the tension spring 10 is in a stretched state. When the piston rod 8 moves downward, it will drive the upper pressing block 9 downward, and the supporting frame 18 will move downward due to the gravity of the shell, so that the shell can be in a suitable tight-mouth position. And when the upper pressing block 9 descends, it will also drive the positioning rod 16 to descend. Then as the positioning rod 16 descends, the spring telescopic rod 13 starts to contract, and when contracting, it will drive the upper stabilizing block 15 to descend and fit with the lower stabilizing block 12, stabilizing the shell before tight-mouth to prevent the shell from moving during tight-mouth. Then the upper pressing block 9 continues to move downward to cooperate with the lower pressing block 6 to perform the tight-mouth operation on the shell. After the tight-mouth is completed, close the gas cylinder 4. At this time, the piston rod 8 is no longer pushed by the gas, and the tension spring 10 starts to reset to its normal state. The gas in the air cylinder 7 overflows from the through hole 71 to the outside, and the upper pressing block 9 starts to rise and reset.

[0032] When the upper pressing block 9 resets, it will drive the positioning rod 16 to rise and lift the upper stabilizing block 15 for the next shell stabilization. Then when the upper pressing block 9 continues to move upward, it will contact the trigger frame 21 and drive the trigger frame 21 to move upward, thereby driving the supporting frame 18 to lift the shell. Finally, move the lower stabilizing block 12 so that it slides on the placement table 1. At this time, the upper stabilizing block 15 is also driven by the lower stabilizing block 12 and starts to move away from the gas cylinder 4. And at this time, the fixed block 14 will move on the inclined surface of the extension rod 17. When the lower stabilizing block 12 moves to the farthest position from the gas cylinder 4, the upper stabilizing block 15 fits with the lower stabilizing block 12, and at this time, it is more convenient to take out the shell.

[0033] In this way, in the event of special situations such as power outages or power cuts, the gas cylinder 4 can be replaced as the power source to ensure the continuous progress of production, avoid a significant decline in production efficiency, maintain a high quality standard during tight-mouth, and make it more convenient to take out the ammunition.

All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
