Description

Technical Field

[0001] This invention relates to the field of ammunition production technology, and in particular to a primer pressing device suitable for the assembly and production of various types of ammunition. Background Technology

[0002] Primer loading is a critical process in ammunition production, and the depth of the primer charge directly determines the firing performance and safety of the ammunition.

[0003] Currently, the primer pressing process uses a horizontal intermittent stamping assembly method, but this intermittent pressing method has the problem of low assembly efficiency.

[0004] At the same time, with the cartridge lying flat, it is difficult to control the state of the primer, which is in a free and unstable state in the side-standing direction, when it is pressed into the cartridge. This can easily lead to situations where the primer is tilted after being pressed and the pressing depth is inconsistent.

[0005] In addition, if the primer is pressed too shallowly or too deeply, it may cause premature firing of the primer or accidental firing of the ammunition during transportation, or the ammunition may fail to fire properly, which seriously affects the quality, lethality and safety of the ammunition. The production process involves a lot of sensitive energetic agents, and stamping poses a high safety risk.

[0006] It is evident that the current deficiencies in primer pressing production efficiency, product quality, and production safety severely restrict the efficiency and support capabilities of ammunition production.

[0007] Therefore, how to provide a primer loading device for use in automated ammunition production, and solve the problems of low efficiency, poor product quality, and high safety risks in the current ammunition assembly production of cartridge pressing primers, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] In view of the above problems, the present invention provides a primer pressing device for overcoming or at least partially solving the above problems. It solves the problems of low production efficiency, poor product quality, and high safety risks in existing ammunition assembly production by employing a vertical continuous pressing method and a size compensation structure, enabling rapid, accurate, and safe pressing of primers into cartridges in the assembly production of various ammunition types, while meeting the requirements of automated ammunition assembly production.

[0009] This invention provides the following solution:

[0010] A primer pressing device, comprising:

[0011] A frame assembly, wherein a pressure rod support cam and a support column support cam are respectively provided at the upper and lower ends of the frame assembly;

[0012] The main shaft passes through the support column cam and the pressure rod cam sequentially from bottom to top. Between the support column cam and the pressure rod cam, the main shaft is fixedly arranged with a support column turntable, a main turntable, a positioning turntable and a pressure rod turntable sequentially from bottom to top. The lower surface of the positioning turntable abuts against the upper surface of the main turntable.

[0013] The support column turntable has multiple support column assemblies that can slide vertically evenly distributed in the radial direction. The first support wheel at the lower end of the support column assembly is connected to the first guide groove of the support column support cam, so that the support column assembly can be driven to move up and down reciprocally during the rotation of the support column turntable; the upper end of the support column assembly is used to support the base fire.

[0014] Multiple pressing molds that can slide vertically are evenly installed in the center of the main turntable. Each pressing mold is provided with a pressing mold spring. An outer vertical edge is concentrically fixed on the outside of the main turntable. The upper plane of the pressing mold is used to support the bottom plane of the cartridge.

[0015] The positioning turntable contains multiple vertically slidable positioning molds evenly distributed along its central axis, and each positioning mold is provided with a positioning mold spring on its exterior.

[0016] Multiple horizontally sliding wedge blocks are evenly embedded in the upper part of the pressure rod turntable along the radial direction of the axis. Each wedge block assembly is equipped with a compensation spring between itself and the main shaft. A guide post is provided inside the compensation spring. Multiple vertically sliding pressure rod assemblies are evenly distributed on the pressure rod turntable along the radial direction of the axis. The second support wheel of the pressure rod assembly is connected to the second guide groove of the pressure rod support cam so that the pressure rod assembly is driven to reciprocate up and down during the rotation of the pressure rod turntable.

[0017] The wedge assembly includes a wedge body and a follower wheel connected to the wedge body via a pin. A horizontal inner cam is provided above the pressure rod support cam, and a non-circular curved surface through hole is formed at the middle position of the horizontal inner cam. The follower wheels included in each wedge assembly are located within the non-circular curved surface through hole. During the rotation of the pressure rod turntable, the wedge body moves horizontally under the action of the curved surface within the non-circular curved surface through hole. The lower working inclined surface of the wedge body contacts or disengages from the pressure bearing wheel at the top of the pressure rod assembly, making the height of the bottom plane of the cartridge case consistent. This allows the primer to be pressed into the bottom cavity of the cartridge case to a consistent depth through the opposing pressure of the support column assembly and the bottom plane of the cartridge case with consistent height.

[0018] Preferably, the support column assembly further includes a pressure head and a guide rod, the pressure head being connected to the lower end of the guide rod; the pressure head is used to penetrate into the inner hole of the positioning mold and the inner hole of the cartridge during the downward movement of the pressure rod assembly, so that the pressure head contacts the inner bottom surface of the positioning mold and compresses the positioning mold spring to make the lower bottom surface of the positioning mold fit against the opening plane of the cartridge, thereby achieving positioning of the axis of the cartridge and the opening plane of the cartridge.

[0019] Preferably, the support column assembly further includes a guide wheel, which is disposed in the middle of the guide rod. The axes of the guide wheel and the second support wheel are on the same plane, and the axis of the pressure wheel is distributed at a 90° angle to the axis of the second support wheel.

[0020] Preferably, the assembly further includes multiple guide blocks and multiple buffer blocks. The multiple guide blocks are fixedly installed below the upper plane of the frame assembly. The multiple guide blocks are distributed radially along the main shaft and are located above the pressure rod support cam. The buffer block is movably installed between two of the guide blocks. The upper end of the buffer block is connected to the frame assembly through a spring assembly.

[0021] Preferably, the number of the support column assembly, the positioning mold, the wedge block assembly, the compensation spring, the guide column, the pressure rod assembly, the positioning mold spring, the mounting mold, and the mounting mold spring are all equal, and the axes of the support column assembly, the positioning mold, the pressure rod assembly, the positioning mold spring, the mounting mold, and the mounting mold spring are all coincidentally distributed.

[0022] Preferably, the system further includes an installation platform, through which the main shaft passes so that the main turntable and the support column turntable are located on the upper and lower sides of the installation platform, respectively.

[0023] Preferably, the device further includes a bottom fire feed plate disposed at the same height as the lower plane of the main turntable, wherein the circumference of the bottom fire feed plate is arranged tangentially to the circumference of the main turntable.

[0024] Preferably, the device further includes a cartridge feed plate disposed at the same height as the upper plane of the pressing mold within the main turntable, wherein the circumference of the cartridge feed plate is arranged tangentially to the circumference of the main turntable.

[0025] Preferably, both the primer feed plate and the cartridge feed plate are connected to the main shaft via a gear set of a transmission assembly.

[0026] Preferably, the upper end of the spindle is connected to the upper end of the frame assembly via a spindle support.

[0027] According to specific embodiments provided by the present invention, the present invention discloses the following technical effects:

[0028] This application provides a primer loading device that achieves precise positioning and loading of the vertical cartridge and primer by synchronously rotating the primer feed plate, main turntable, and cartridge feed plate, and by having the pressure rod assembly and support column assembly move up and down along a curve under the action of the corresponding cam. This allows for component docking and loading during continuous conveying of the primer and cartridge, without separately occupying the time required for component docking, pressing, and primer / cartridge feeding. This avoids the time-consuming idle strokes of conventional stepping logistics, significantly improving ammunition assembly efficiency. The vertical in-mold gradual docking and loading method overcomes the shortcomings of the current intermittent primer pressing method, which results in uncontrollable pressing of the primer into the cartridge and leads to primer assembly misalignment, as well as the safety risks of impact on sensitive agents, caused by the primer being in a free and unstable state in the side-standing position when the cartridge is lying flat.

[0038] 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 a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 This invention provides a primer pressing device, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the device may include:

[0040] The frame assembly 13 is provided with a pressure rod support cam 10 and a support column support cam 27 at its upper and lower ends, respectively.

[0041] The main shaft 26 passes through the support column cam 27 and the pressure rod support cam 10 from bottom to top. Between the support column cam 27 and the pressure rod support cam 10, the main shaft 26 is fixedly arranged with a support column turntable 3, a main turntable 6, a positioning turntable 21, and a pressure rod turntable 9 from bottom to top. The lower surface of the positioning turntable 21 abuts against the upper surface of the main turntable 6.

[0042] The support column turntable 3 has multiple support column assemblies 2 that can slide vertically evenly distributed in the radial direction. The first support wheel at the lower end of the support column assembly 2 is connected to the first guide groove of the support column support cam 27 so that the support column assembly 2 can move up and down reciprocally during the rotation of the support column turntable 3. The upper end of the support column assembly 2 is used to support the base fire 29.

[0043] Multiple vertically sliding pressing molds 24 are evenly distributed in the center of the main turntable 6. Each pressing mold 24 is provided with a pressing mold spring 25. An outer vertical edge 23 is concentrically fixed on the outside of the main turntable 6. The upper plane of the pressing mold is used to support the bottom plane of the cartridge 28.

[0044] The positioning turntable 21 contains a plurality of vertically sliding positioning molds 8 that are evenly distributed in the central radial direction. Each positioning mold 8 is provided with a positioning mold spring 22.

[0045] Multiple horizontally sliding wedge assemblies 16 are evenly embedded in the upper part of the pressure rod turntable 9 along the radial direction of the axis. Each wedge assembly 16 is equipped with a compensation spring 17 between itself and the main shaft 26. A guide post 18 is provided inside the compensation spring 17. Multiple vertically sliding pressure rod assemblies 20 are evenly distributed on the pressure rod turntable 9 along the radial direction of the axis. The second support wheel 20-4 of the pressure rod assembly 20 is connected to the second guide groove of the pressure rod support cam 10 so that the pressure rod assembly 20 is driven to move up and down reciprocally during the rotation of the pressure rod turntable 9.

[0046] The wedge assembly 16 includes a wedge body 16-1 and a follower wheel 16-3 connected to the wedge body 16-1 via a pin 16-2. A horizontal inner cam 15 is provided above the pressure rod support cam 10, and a non-circular curved surface through hole is formed at the middle position of the horizontal inner cam 15. The follower wheel 16-3 included in each of the wedge assemblies 16 is located in the non-circular curved surface through hole. During the rotation of the pressure rod turntable 9, the wedge body 16-1 moves horizontally under the action of the curved surface in the non-circular curved surface through hole. The lower working inclined surface of the wedge body 16-1 contacts or disengages from the pressure roller 20-5 at the top of the pressure rod assembly 20, so that the height of the bottom plane of the cartridge is consistent. In order to achieve the pressing of the primer into the bottom cavity of the cartridge by the opposing pressure of the support column assembly 2 with consistent height and the bottom plane of the cartridge with consistent height, and the pressing depth is consistent.

[0047] The primer loading device provided in this application embodiment achieves precise positioning and loading of the vertical cartridge and primer by the up-and-down movement of the pressure rod assembly 20 and the support column assembly 2 along a curve under the action of the corresponding cam. It realizes the docking and loading of components during continuous transmission of the primer and cartridge, which greatly improves the assembly efficiency of ammunition. It overcomes the defects caused by the intermittent pressing method when the cartridge is lying flat, which leads to uncontrollable pressing of the primer into the cartridge and the resulting skewed primer assembly and safety risks of impact on sensitive agents. The horizontal floating of the wedge block body 16-1 compensates for the length of the cartridge, realizes the same height of the bottom plane reference, solves the problem of large difference in the depth of primer loading into the cartridge, and avoids the phenomenon of premature primer firing or accidental firing of ammunition or failure to fire normally due to the primer being loaded too shallow or too deep. It improves the quality, lethality and safety of ammunition products, and has a positive effect on improving the efficiency of ammunition assembly production, product quality and ammunition production support capabilities.

[0048] To achieve precise positioning of the cartridge opening, this embodiment of the application may provide that the support column assembly 2 further includes a pressure head 20-1 and a guide rod 20-2. The pressure head 20-1 is connected to the lower end of the guide rod 20-2. The pressure head 20-1 is used to penetrate into the inner hole of the positioning mold 8 and the inner hole of the cartridge during the downward movement of the pressure rod assembly 20, so that the pressure head 20-1 contacts the inner bottom surface of the positioning mold 8 and compresses the positioning mold spring 22 to make the lower bottom surface of the positioning mold 8 fit against the opening plane of the cartridge, thereby achieving positioning of the axis of the cartridge and the opening plane of the cartridge.

[0049] In order to realize the various actions of the support column assembly 2, the embodiment of this application may also provide that the support column assembly 2 further includes a guide wheel 20-3, the guide wheel 20-3 is disposed in the middle of the guide rod 20-2, the axes of the guide wheel 20-3 and the second support wheel 20-4 are on the same plane, and the axis of the pressure wheel 20-5 is distributed at 90° with the axis of the second support wheel 20-4.

[0050] Furthermore, embodiments of this application may also provide multiple guide blocks 19 and multiple buffer blocks 11. The multiple guide blocks 19 are fixedly installed below the upper plane of the frame assembly 13. The multiple guide blocks 19 are distributed radially along the main shaft 26 and are located above the pressure rod support cam 10. The buffer block 11 is movably installed between two of the guide blocks 19. The upper end of the buffer block 11 is connected to the frame assembly 13 through a spring assembly 12.

[0051] The number of the support column assembly 2, the positioning mold 8, the wedge block assembly 16, the compensation spring 17, the guide column 18, the pressure rod assembly 20, the positioning mold spring 22, the mounting mold 24, and the mounting mold spring 25 are all equal, and the axes of the support column assembly 2, the positioning mold 8, the pressure rod assembly 20, the positioning mold spring 22, the mounting mold 24, and the mounting mold spring 25 are all coincidentally distributed.

[0052] To facilitate the overall installation of the device, this embodiment may also include an installation platform 4, through which the main shaft 26 passes so that the main turntable 6 and the support column turntable 3 are located on the upper and lower sides of the installation platform 4, respectively.

[0053] It is understood that the cartridge case and primer provided in the device of this application embodiment can be supplied to the corresponding positions by manual or automatic feeding.

[0055] In order to achieve a set of drive mechanisms to drive feeding and pressing, this application embodiment can also provide that the primer feed plate 5 and the cartridge feed plate 7 are both meshed with the main shaft 26 through the gear set of the transmission assembly 1.

[0056] To facilitate the installation of the spindle 26, this embodiment of the application may also provide that the upper end of the spindle 26 is connected to the upper end of the frame assembly 13 via the spindle upper support 14.

[0057] The connection relationships of the various components of the device provided in the embodiments of this application and its usage method are described in detail below.

[0062] Multiple horizontally sliding wedge assemblies 16 are evenly embedded in the upper part of the pressure rod turntable 9 along the axial direction. Each wedge assembly 16 is equipped with a compensating spring 17 between itself and the main shaft 26. A guide post 18 is provided inside the compensating spring 17. Multiple vertically sliding pressure rod assemblies 20 are evenly distributed on the pressure rod turntable 9 along the axial direction. The second support wheel 20-4 of the pressure rod assembly 20 is in contact with the upper working surface of the pressure rod support cam 10, which is fixed and concentrically installed on the outside of the pressure rod turntable 9. The pressure bearing wheel 20-5 at the top of the pressure rod assembly 20 is in contact with or out of contact with the lower working inclined surface of the wedge body 16-1 in the wedge assembly 16.

[0063] The frame assembly 13 is fixedly mounted on the mounting platform 4. A primer feed plate 5 is positioned at the same height as the lower plane of the main turntable 6, with the circumference of the primer feed plate 5 tangent to the circumference of the main turntable 6. A cartridge feed plate 7 is positioned at the same height as the upper plane of the pressing mold 24 inside the main turntable 6, with the circumference of the cartridge feed plate 7 tangent to the circumference of the main turntable 6. The cartridge feed plate 7 is positioned above the primer feed plate 5, and both the primer feed plate 5 and the cartridge feed plate 7 are meshed with the main shaft 26 via the gear set of the transmission assembly 1.

[0064] Multiple guide blocks 19 are fixedly installed below the upper plane of the frame assembly 13. The multiple guide blocks 19 are distributed radially along the main shaft 26 and are located above the pressure rod support cam 10. A buffer block 11 is movably installed between two guide blocks 19. The upper end of the buffer block 11 is connected to the frame assembly 13 through a spring assembly 12.

[0065] A pin 16-2 is mounted on the upper surface of the wedge body 16-1 of the wedge assembly 16, and a follower wheel 16-3 is provided on the upper end of the pin 16-2.

[0066] The pressure head 20-1 of the pressure rod assembly 20 is installed at the lower end of the guide rod 20-2 via a threaded connection. A guide wheel 20-3 is installed in the middle part of the guide rod 20-2, a second support wheel 20-4 is installed at the upper end of the guide rod 20-2, and a bearing wheel 20-5 is installed at the top of the guide rod 20-2. The axes of the guide wheel 20-3 and the second support wheel 20-4 are on the same plane, and the axis of the bearing wheel 20-5 is distributed at a 90° angle to the axis of the second support wheel 20-4.

[0067] The number of the support column assembly 2, positioning mold 8, wedge block assembly 16, compensation spring 17, guide column 18, pressure rod assembly 20, positioning mold spring 22, pressing mold 24 and pressing mold spring 25 are all equal, and the axes of the support column assembly 2, positioning mold 8, pressure rod assembly 20, positioning mold spring 22, pressing mold 24 and pressing mold spring 25 are all coincidentally distributed.

[0068] The working process of the primer pressing device provided in this application embodiment is as follows:

[0069] The primer feed plate 5 and the cartridge feed plate 7 are synchronously rotated with the main shaft 26 at the same circumferential speed through the gears of the transmission assembly 1, driving the support column assembly 2, positioning mold 8, wedge block assembly 16, guide column 18, pressure rod assembly 20, and pressing mold 24 mounted on the main shaft 26 to rotate together with the main shaft 26.

[0070] The cartridges are vertically inserted one by one into the pressing mold 24 in the middle section of the main turntable 6 by the rotation of the upper cartridge feed plate 7. The upper plane of the pressing mold 24 supports the bottom plane of the cartridge. As the main shaft 26 rotates, the lower end of the second support wheel 20-4 of the pressure rod assembly 20 moves downward along the curved surface of the support cam 27, driving the pressure rod assembly 20 to descend on the pressure rod turntable 9. Gradually, the pressure head 20-1 of the pressure rod assembly 20 is inserted into the inner hole of the positioning mold 8 and the inner hole of the cartridge. Then, the pressure head 20-1 contacts the inner bottom surface of the positioning mold 8 and compresses the positioning mold spring 22 so that the lower bottom surface of the positioning mold 8 fits against the opening plane of the cartridge, thus completing the positioning of the axis of the cartridge and the opening plane of the cartridge.

[0071] The primers are fed into the top of the support column assembly 2 one by one by the rotation of the primer feed plate 5 located in the lower layer. The support column assembly 2 moves upward along the curved surface of the support column support cam 27, which drives the primers at the top of the support column assembly 2 to gradually enter the inner cavity of the pressing mold 24 from the bottom of the pressing mold 24. The primers are then assembled in the inner cavity of the pressing mold 24 and gradually pressed into the bottom cavity of the cartridge.

[0072] The pressure rod assembly 20 continues to move downward along the curved surface of the support cam 27, pressing the positioning mold 8 down and into the inner cavity of the pressing mold 24, maintaining a consistent working surface height for the pressure rod support cam 10. Subsequently, the wedge assembly 16 at the upper end of the pressure rod assembly 20, under the combined action of the extension of the compensating spring 17 installed outside the guide post 18 and the follower wheel 16-3 at the upper end of the wedge assembly 16 along the inner curved surface of the horizontal inner cam 15, moves outward horizontally until the lower inclined surface of the wedge body 16-1 contacts the bearing wheel 20-5 at the top of the pressure rod assembly 20. The wedge body 16 is supported by the bearing wheel 20-5 at the top of the pressure rod assembly 20 on the lower inclined surface of the wedge body 16-1, compensating for the pressure applied by the pressure head 20-1 at the lower end of the pressure rod assembly 20 to the mouth plane of cartridges of different lengths, and ensuring a consistent height of the bottom plane of the cartridges.

[0073] Since the support column assembly 2 ensures that the top of the support column assembly 2 rises at a consistent height through the fixed curved surface of the support column support cam 27, the primer is fully pressed into the bottom cavity of the cartridge by the consistent support column assembly 2 and the consistent bottom plane of the cartridge, and the pressing depth is consistent, thus completing the process of pressing the primer into the cartridge.

[0074] After the primer is pressed, as the main shaft 26 continues to rotate, the support column assembly 2 moves downward along the curved surface of the support column support cam 27, and the upper end face of the support column assembly 2 gradually separates from the bottom of the cartridge and the inner cavity of the pressing mold 24; the pressure rod assembly 20 and the cartridge continue to maintain a constant height with the wedge block assembly 16 through the working surface curved surface of the pressure rod support cam 10, and the upper edge of the second support wheel 20-4 of the pressure rod assembly 20 gradually enters below the buffer block 11.

[0075] The wedge assembly 16 at the upper end of the pressure rod assembly 20 is compressed by the compensating spring 17 under the action of the follower wheel 16-3 along the inner curved surface of the horizontal inner cam 15. The lower wedge assembly 16 moves horizontally in the radial direction toward the axis of the main shaft 26 until the lower inclined surface of the wedge body 16-1 disengages from the pressure wheel 20-5 at the top of the pressure rod assembly 20.

[0076] The pressure rod assembly 20 rises rapidly along the working surface of the pressure rod support cam 10 via the second support wheel 20-4. The upper edge of the second support wheel 20-4 contacts the lower plane of the buffer block 11, which can float up and down, thus smoothly limiting the upward sliding of the pressure rod assembly 20. As the pressure rod assembly 20 rises, the lower end face of the pressure head 20-1 gradually separates from the cartridge mouth and the positioning mold 8. The positioning mold 8 rises under the action of the positioning mold spring 22 and separates from the contact with the cartridge mouth. The loading mold 24 rises under the action of the loading mold spring 25 to the same horizontal plane as the cartridge feed plate 7. The main turntable 6 continues to rotate, driving the cartridge that has completed the primer loading into the next process.

[0077] In summary, the primer loading device provided in this application achieves precise positioning and loading of the vertical cartridge and primer by synchronously rotating the primer feed plate, main turntable, and cartridge feed plate, and by having the pressure rod assembly and support column assembly move up and down along a curve under the action of the corresponding cam. This allows for component docking and loading during continuous conveying of the primer and cartridge, without separately occupying time for component docking, pressing, and primer / cartridge feeding, thus avoiding the time-consuming idle strokes of conventional stepping logistics and significantly improving ammunition assembly efficiency. The vertical in-mold gradual docking and loading method overcomes the defects and safety risks associated with the intermittent pressing method of the primer, where the primer is in a free and unstable state in the side-standing direction when the cartridge is lying flat, resulting in uncontrollable pressing of the primer into the cartridge and causing primer assembly misalignment.

[0078] Simultaneously, the device moves outward or inward horizontally in the direction of the wedge block assembly under the action of the horizontal inner cam and the compensating spring, causing the pressure roller on the pressure rod assembly to contact or disengage from the lower plane of the wedge block body above. This achieves a consistent bottom plane reference height for different cartridges with varying lengths after pressing. The horizontal floating of the wedge block body compensates for the cartridge length, achieving equal bottom plane reference height. This solves the problem of large differences in the depth of the primer pressing into the cartridge, avoiding premature primer firing or accidental firing of ammunition during transportation due to insufficient or excessive primer pressing, and improving the quality, lethality, and safety of ammunition products.
