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

[0028] Example 1

[0029] This embodiment aims to facilitate the resolution of problems such as burrs, scratches, and wrinkles that occur during the sealing process of ammunition cartridges, as well as deformation caused by friction during the sealing process. Please refer to [link to relevant documentation]. Figure 1-7 A tooling for processing the mouthpiece of ammunition cartridge includes a mouthpiece assembly 1. The mouthpiece assembly 1 is used to process the mouthpiece of ammunition cartridge. A transmission device 2 is installed on one side of the mouthpiece assembly 1. The transmission device 2 is designed to transmit the power required for the mouthpiece assembly 1 during the mouthpiece processing.

[0030] On the other side of the closing assembly 1, there is a feeding assembly 3 for transporting the ammunition cartridge to be closed to the closing assembly 1. The feeding assembly 3 can transport the ammunition cartridge to be processed to the closing assembly 1.

[0031] One side of the feeding component 3 is equipped with a feeding component 4 for pushing the ammunition cartridge to be closed to the closing component 1 and for extracting it from the closing component 1 after processing. The design of the feeding component 4 allows the ammunition cartridge to be extracted from the closing component 1 and fed in.

[0032] In this embodiment: the closing assembly 1 includes a rotating disk 101, a spring steel strip 102 is installed on one side of the rotating disk 101, the spring steel strip 102 can return to its original shape after deformation, an adjustment hole 103 is opened on one side of the spring steel strip 102, and a closing block 104 for closing the ammunition cartridge is installed at one end of the spring steel strip 102 located at the adjustment hole 103. The inner side of the closing block 104 is an arc-shaped design 116. The closing block 104 has 4 joints to form a complete cone. The inner side of the closing block 104 is rotatably connected to a rotating wheel 105 for preventing friction from deforming the ammunition cartridge.

[0033] During the closing process, when the ammunition cartridge that needs to be closed is pushed into the closing assembly 1, the ammunition cartridge will come into contact with the inner wall of the closing block 104 when it is pulled out after closing, thereby generating friction. Friction may cause the ammunition cartridge to deform and affect the quality of closing. The design of the rotating wheel 105 can prevent the ammunition cartridge from rubbing against the closing block 104 through contact with the rotating wheel 105, thereby reducing the deformation of the ammunition cartridge caused by friction.

[0034] One end of the tapered block 104 has a threaded hole 106, and a screw 107 is threaded into the threaded hole 106. The screw 107 passes through the tapered block 104 and is threaded into the adjusting hole 103. The screw 107 and the tapered block 104 are rotatably connected. Later, the size of the inner diameter of the cone formed by the tapered block 104 can be controlled by rotating the screw 107. Figure 7 As shown, the adjusted closing block 104 increases the inner diameter, enabling the equipment to process ammunition cartridges of different sizes.

[0035] In this embodiment: the closing assembly 1 further includes a rotating round tube 110. The closing assembly 1 further includes a rotating round tube 110. A plurality of round grooves 111 are opened on one side of the rotating round tube 110. The round grooves 111 are arrayed inside the rotating round tube 110. An arc-shaped block 108 is fixedly connected to the outside of the closing block 104. A protruding inclined strip 109 is fixedly connected to the arc-shaped block 108. A column 112 for pressing the protruding inclined strip 109 is installed in each of the round grooves 111. The column 112 is used to abut against the protruding inclined strip 109.

[0036] When the rotating tube 110 drives the column 112 to rotate, when the column 112 rotates to a certain position, it will come into contact with the protruding inclined bar 109. After contact, it will squeeze the protruding inclined bar 109. Multiple columns 112 are installed inside the rotating tube 110, so they will continuously squeeze the protruding inclined bar 109. The squeezing of the column 112 on the protruding inclined bar 109 causes the pressure to tighten the closing block 104 inward, thereby completing the squeezing and closing of the ammunition cartridge. A first gear 113 is fixedly installed on the other side of the rotating tube 110. The first gear 113 is fixed inside the rotating tube 110 and can provide power to the rotating tube 110 through the first gear 113.

[0037] The rotating cylinder 112 of the rotating tube 110 also rotates together. Multiple cylinders 112 are installed inside the rotating tube 110. During the rotation of the rotating tube 110, the cylinders 112 repeatedly abut against the protruding diagonal strip 109. At the same time, the closing block 104 is repeatedly tightened, thus completing the repeated tightening of the ammunition cartridge during the rotation, making the closing block 104 more precise in closing the ammunition cartridge.

[0038] In this embodiment, the rotating disk 101 has a mounting groove 114 in the middle of one side of the spring steel bar 102. An auxiliary rod 115 is threadedly connected to the mounting groove 114 to prevent deformation of the ammunition cartridge during the closing process. The auxiliary rod 115 can be inserted into the ammunition cartridge. When the closing block 104 squeezes the ammunition cartridge, the auxiliary rod 115 can prevent the ammunition cartridge from deforming due to excessive squeezing by the closing block 104. The design of the mounting groove 114 facilitates the replacement and maintenance of the auxiliary rod 115 in the later stage. Before processing, the appropriate auxiliary rod 115 can be selected and installed according to the size of the ammunition cartridge to be closed, which increases the adaptability of the equipment and enables the equipment to close ammunition cartridges of different sizes.

[0039] In this embodiment: the transmission device 2 includes a drive motor 202, the output shaft of the drive motor 202 is fixedly connected to a transmission column 201, the transmission column 201 is fixedly connected to the rotating disk 101, the drive motor 202 drives the transmission column 201 fixedly connected to the rotating disk 101, thereby causing the rotating disk 101 to rotate together. The direct transmission makes the rotation of the rotating disk 101 more stable, which is beneficial to the quality of the closing.

[0040] A transmission gear 203 is fixedly connected to the side wall of the transmission column 201. The transmission gear 203 meshes with a second gear 204. A bearing 205 is sleeved inside the second gear 204. The design of the bearing 205 allows the second gear 204 to rotate freely, thereby better playing the role of transmission. A fixing rod 206 for fixing the second gear 204 is sleeved inside the bearing 205. One end of the fixing rod 206 is installed on one side of the drive motor 202. The fixing rod 206 provides a fixed fulcrum for the second gear 204. The second gear 204 meshes with the first gear 113.

[0041] The rotation of the transmission column 201 drives the transmission gear 203 to rotate together. The transmission gear 203 transmits power to the meshing second gear 204. While the second gear 204 rotates, it transmits power to the first gear 113 that meshes with the second gear 204, thus realizing the opposite rotation of the first gear 113 and the transmission column 201. The first gear 113 then drives the rotating tube 110 to rotate in the opposite direction.

[0042] In this embodiment: the feeding assembly 3 includes a feeding tray 301 disposed on one side of the closing assembly 1. The feeding tray 301 has a feeding groove 302. A servo motor 303 is installed on one side of the feeding tray 301 to drive its rotation. The servo motor 303 can rotate intermittently, thus allowing sufficient time for the ammunition cartridge to close within the closing assembly 1. A motor mounting base 304 is installed below the servo motor 303, and a fixing platform 305 is fixedly connected below the motor mounting base 304. Below 01 is a guide plate 306 for guiding ammunition cartridges into the feeding trough 302. The guide plate 306 can continuously guide the ammunition cartridges into the feeding trough 302 on the feeding tray 301. The feeding trough 302 is a semi-circular design that can accommodate ammunition cartridges and prevent them from rolling off during the feeding process. A conveyor belt 307 is installed on one side of the feeding tray 301 to transport the closed missile cartridges to the next processing point. The conveyor belt 307 can transport the closed ammunition cartridges to the next processing point.

[0043] In this embodiment: the pumping component 4 includes a mounting base 401 mounted on a fixed platform 305. A support plate 414 is fixedly connected to one side of the mounting base 401. A sliding groove 402 is provided on the support plate 414. A sliding block 403 is slidably connected in the sliding groove 402. A lower clamping block 404 for clamping ammunition cartridges is installed above the sliding block 403. A round hole 405 is provided on the lower clamping block 404. A round rod 406 is movably connected in the round hole 405. An upper clamping block 407 is fixedly connected to the upper part of the round rod 406. The function of the round rod 406 is to restrict the space between the upper clamping block 407 and the lower clamping block 404, so that the upper clamping block 407 and the lower clamping block 404 can complete the clamping action of the ammunition cartridges.

[0044] A hydraulic rod 408 is connected to one side of the lower clamping block 404. The hydraulic rod 408 is mounted on the mounting base 401. The mounting base 401 can provide a fixed point for the hydraulic rod 408. The upper clamping block 407 can slide together with the lower clamping block 404 under the thrust of the hydraulic rod 408 via the round rod 406.

[0045] In this embodiment: the pumping assembly 4 also includes a support rod 409 fixedly connected to the support plate 414. A square plate 410 is fixedly connected above the support rod 409. A groove 411 is provided on the square plate 410. A slider 412 is slidably connected in the groove 411. A telescopic motor 413 is fixedly connected below the slider 412. The power output end of the telescopic motor 413 is fixedly connected to the upper clamping block 407. When the telescopic motor 413 extends, it drives the upper clamping block 407 to slide downward, so that the upper clamping block 407 and the lower clamping block 404 can clamp the ammunition cartridge.

[0046] After the ammunition cartridge is clamped by the upper clamping block 407 and the lower clamping block 404, the ammunition cartridge is pushed into the closing assembly 1 by the hydraulic rod 408. After closing, the ammunition cartridge is pulled out by the hydraulic rod 408. At the same time, the upper clamping block 407 slides upward by the telescopic motor 413, thereby releasing the ammunition cartridge after closing. Then, the ammunition cartridge after closing is sent to the conveyor belt 307 by the feeding plate 301.

[0047] Working principle: First, adjust the position of the closing block 104 according to the size of the ammunition cartridge to be closed, and replace the required auxiliary rod 115. Then start the equipment. At this time, the ammunition cartridge to be processed will enter the feeding trough 302 through the guide plate 306. At this time, the servo motor 303 will rotate intermittently, and at the same time drive the feeding plate 301 to rotate intermittently. When the feeding plate 301 sends the ammunition cartridge to be closed to the closing assembly 1, the hydraulic rod 408 in the conveying assembly 4 will push the lower clamping block 404 to slide towards the closing assembly 1. At the same time, the upper clamping block 407 and the telescopic motor 413 will slide together through the round rod 406. At the same time, the telescopic motor 413 will start and push the upper clamping block 407 down, thereby clamping the ammunition cartridge to be closed.

[0048] After the ammunition cartridge is pushed into the closing assembly 1, the drive motor 202 drives the transmission column 201 to rotate. Simultaneously, the rotation of the transmission column 201 drives the rotating disk 101 to rotate, which in turn drives the spring steel bar 102 to rotate, and also drives the closing block 104 to rotate. At this time, the transmission teeth 203 on the transmission column 201 also rotate with the transmission column 201. Simultaneously, the second gear 204, which meshes with the transmission teeth 203, also rotates. The rotation of the second gear 204 drives the first gear 113, which meshes with the second gear 204, to rotate. The rotation of the first gear 113 drives the rotating tube 110 to rotate as well. At this time, the rotating tube 110 and the rotating disk 101 rotate in opposite directions.

[0049] As the round tube 110 rotates, it will also drive the column 112 to rotate. When the column 112 comes into contact with the protruding inclined strip 109, it will squeeze the protruding inclined strip 109 inward. When the protruding inclined strip is squeezed, it will drive the arc block 108 and the closing block 104 to squeeze inward together. The inner side of the closing block 104 is arc-shaped 116, which will squeeze the ammunition cartridge and rotate continuously while squeezing, thereby achieving precise closing of the ammunition cartridge around one circumference.

[0050] When the closing block 104 is compressed, it simultaneously transmits pressure to the spring steel strip 102. The spring steel strip 102 deforms under compression. When the column 112 rotates away from the protruding inclined strip 109, the spring steel strip 102 will drive the closing block 104 to return to its original state. After the ammunition cartridge is closed, the hydraulic rod 408 will drive the lower clamping block 404 and the upper clamping block 407 to pull the closed ammunition cartridge out of the closing assembly 1. After being pulled out, the telescopic motor 413 will drive the upper clamping block 407 to slide upward, so that the ammunition cartridge can move to the conveyor belt 307 with the rotation of the feeding plate 301, and then proceed to the next step of processing.

[0052] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
