[0002] In the production of military ammunition, due to the characteristics of the propellant charge itself, the processing process of the propellant charge is an extremely dangerous process. During the processing of the propellant charge, if there is a slight carelessness, accidents such as combustion or explosion will occur, resulting in damage to personnel and property. At the same time, due to the limitations of the existing processing technology, during the production process of the propellant charge, its production rhythm is also limited and cannot be accelerated, which restricts the rapid production of ammunition and the improvement of production capacity.

[0003] In the prior art, generally, the propellant charge is turned on a common lathe by manual operation. This production process is extremely dangerous, and the operator needs to face the cutting of the propellant charge directly. In case of a deflagration accident, the personnel have no time to escape, and it is extremely easy to cause problems such as burns. In addition, it takes several minutes to complete the processing of one propellant charge by the above operation, and the processing speed is slow, seriously restricting the acceleration of production.

[0029] Please refer to together Figures 1 to 8, the description of the device for processing the length of the propellant grain provided by the present utility model will be given now. The device for processing the length of the propellant grain includes a frame 1, a lifting and pushing arm 2, a translation pushing rod 3, a telescopic driving member 4, and a sawing assembly 5. An upper hopper 6 with an upward opening is provided on the frame 1. The lifting and pushing arm 2 is connected to the frame 1 and extends upward into the upper hopper 6. The lifting and pushing arm 2 is used to push one of the propellant grains 8 upward so that the propellant grain 8 is removed from the upper hopper 6. A supporting bar seat 11 for supporting the propellant grain 8 is provided on the frame 1 at the discharging side of the upper hopper 6. The translation pushing rod 3 is arranged above the supporting bar seat 11 and is used to axially push the propellant grain 8 away from the upper hopper 6. The sawing assembly 5 and the telescopic driving member 4 are respectively located on both sides of the discharging end of the supporting bar seat 11. The telescopic driving member 4 is used to push the propellant grain 8 to the position of the sawing assembly 5, and the sawing assembly 5 is used to saw the propellant grain 8.

[0030] For the device for processing the length of the propellant grain provided in this embodiment, compared with the prior art, the device for processing the length of the propellant grain provided in this embodiment uses the lifting and pushing arm 2 below the frame 1 to sequentially push the single propellant grain 8 in the upper hopper 6 upward, so that the single propellant grain 8 is removed from the upper hopper 6 and transferred to the supporting bar seat 11. The translation pushing rod 3 horizontally pushes the propellant grain 8 on the supporting bar seat 11 to be separated from the supporting bar seat 11, and then uses the telescopic driving member 4 to push the peripheral wall of the propellant grain 8, so that the propellant grain 8 rolls to the position of the sawing assembly 5. The two ends of the propellant grain 8 are cut by the sawing assembly 5 to make the propellant grain 8 meet the length requirement. The above device realizes the cutting of the length of the propellant grain 8, improves the processing efficiency of the propellant grain 8, and eliminates potential safety hazards.

[0031] In a possible implementation manner, please refer to Figures 1 to 8 together. A gantry frame 12 is provided on the frame 1. The gantry frame 12 is arranged along the direction of the supporting bar seat 11. The translation pushing rod 3 is slidably connected to the top of the gantry frame 12. The supporting bar seat 11 is located below the gantry frame 12. The translation pushing rod 3 extends in the vertical direction.

[0032] In this embodiment, the gantry frame 12 is provided for installing the translation pushing rod 3. By using the translational movement of the translation pushing rod 3 to push one end face of the propellant grain 8, the propellant grain 8 is axially moved toward the side of the telescopic driving member 4, which is convenient for the subsequent telescopic driving member 4 to push the propellant grain 8 into the position of the sawing assembly 5 for sawing.

[0033] Specifically, the gantry frame 12 is arranged above the supporting bar seat 11, and its width is greater than the length of the supporting bar seat 11, providing sufficient space for the movement of the propellant grain 8 below, so that the propellant grain 8 can smoothly move toward the side of the sawing assembly 5 under the action of the translation pushing rod 3.

[0034] In a possible implementation manner, please refer to Figures 1 to 8, a lifting plate 61 is rotatably connected to the bottom of the feeding hopper 6, and the lifting plate 61 can be lifted upward to cause the propellant column 8 to roll onto the lifting and pushing arm 2. A swinging pull plate 62 is rotatably connected to the frame 1 and is located below the lifting plate 61. A long slot 23 extending in the vertical direction is provided on the lifting and pushing arm 2. One end of the swinging pull plate 62 is provided with a sliding plate 25 slidably connected to the long slot 23. The lifting and pushing arm 2 is used to drive the swinging pull plate 62 to swing vertically, and the swinging pull plate 62 is used to push the lifting plate 61 to swing upward to push the propellant column 8 above the lifting and pushing arm 2.

[0035] In this embodiment, the lifting plate 61 at the bottom of the feeding hopper 6 can lift the propellant column 8, so that the propellant column 8 rolls onto the lifting and pushing arm 2 under the action of the inclination angle of the lifting plate 61. When the lifting and pushing arm 2 moves downward, one end of the swinging pull plate 62 can be pulled down by means of the long slot 23. At this time, the other end of the swinging pull plate 62 on the frame 1 can be lifted upward, realizing the pushing action on the lifting plate 61, and then enabling the propellant column 8 on the lifting plate 61 to roll smoothly onto the lifting and pushing arm 2, facilitating the subsequent ejection of a single propellant column 8.

[0036] Specifically, a plurality of long slots 23 can be arranged at intervals in the horizontal direction, and a sliding plate 25 extending into the long slot 23 is provided on the swinging pull plate 62. When the lifting and pushing arm 2 moves downward, the long slot 23 moves downward synchronously and drives the sliding plate 25 on the swinging pull plate 62 to move downward. At this time, the other end of the swinging pull plate 62 swings upward and plays an upward supporting role on the lifting plate 61, realizing the lifting effect of the lifting plate 61 on the propellant column 8.

[0037] In some embodiments, the lifting and pushing arm 2 includes a lifting driving member 21 and an upper supporting seat 22. The upper supporting seat 22 is connected to the upper end of the lifting driving member 21. The long slot 23 horizontally penetrates through the upper supporting seat 22. The top of the upper supporting seat 22 has an arc-shaped groove 24 for accommodating the propellant column 8. The bottom wall of the arc-shaped groove 24 extends obliquely downward toward the side close to the supporting strip seat 11. The side wall of the feeding hopper 6 adjacent to the supporting strip seat 11 can cooperate with the arc-shaped groove 24 to limit the propellant column 8.

[0038] In this embodiment, the lifting and pushing arm 2 drives the upper supporting seat 22 to move upward by means of the lifting driving member 21, and then the circumferential wall of the propellant column 8 is supported and limited by the arc-shaped groove 24 on the upper supporting seat 22, facilitating the subsequent upward movement of the propellant column 8. During the movement, the inner side wall of the feeding hopper 6 can cooperate with the arc-shaped groove 24 to limit and support the propellant column 8. When the propellant column 8 moves upward with the upper supporting seat 22 to a height higher than the upper edge of the feeding hopper 6, the limiting effect of the inner side wall of the feeding hopper 6 is lost, and the propellant column 8 can automatically roll out of the arc-shaped groove 24 and the propellant column 8 is transferred to the supporting strip seat 11.

[0039] In a possible implementation manner, please refer to Figures 1 to 8, on the frame 1, there is an inclined guide plate 13 located on the outlet side of the feeding hopper 6 and used to guide the propellant column 8 to roll onto the supporting strip seat 11. The top surface of the inclined guide plate 13 gradually extends obliquely downward towards the side close to the supporting strip seat 11.

[0040] In this embodiment, the inclined guide plate 13 can roll and guide the propellant column 8 rolling on the lifting push arm 2, so that the propellant column 8 can roll smoothly into the supporting strip seat 11, which is convenient for axially pushing the propellant column 8 by the translation push rod 3 subsequently.

[0041] In a possible implementation manner, please refer to Figures 1 to 8 , on the supporting strip seat 11, there is a supporting groove 17 with an upward opening, and the supporting groove 17 runs through along the extending direction of the supporting strip seat 11.

[0042] In this embodiment, the supporting groove 17 provided on the supporting strip seat 11 runs through along the extending direction of the supporting strip seat 11, which is convenient to realize the driving of the propellant column 8 under the action of the translation push rod 3, meet the requirement of the axial movement of the propellant column 8, simplifies the driving structure, and improves the processing efficiency.

[0043] In a possible implementation manner, please refer to Figures 1 to 8 , on the frame 1, there is a limiting seat 14 located at the discharging end of the supporting strip seat 11 and protruding upward, and the limiting seat 14 is used to limit the end face of the propellant column 8.

[0044] In this embodiment, there is a limiting seat 14 located at the discharging end of the supporting strip seat 11 on the frame 1. When the translation push rod pushes one end face of the propellant column 8, the propellant column 8 axially moves towards the side close to the limiting seat 14 until the other end face of the propellant column 8 contacts the limiting seat 14. The limiting seat 14 forms axial limitation on the propellant column 8, meets the requirement of accurately moving the propellant column 8 to the sawing position, ensures the accuracy of the cutting dimensions at both ends of the propellant column 8, and improves the processing quality of the propellant column 8 itself.

[0045] In a possible implementation manner, please refer to Figures 1 to 8 , the sawing assembly 5 includes two sawing discs 51 rotatably connected to the frame 1 and protruding upward from the top surface of the frame 1. The two sawing discs 51 are respectively used to saw the two ends of the propellant column 8. There are two material dropping openings 15 on the frame 1 corresponding to and located outside the two sawing discs 51 respectively, and a waste hopper 16 for receiving waste is provided below the material dropping openings 15.

[0046] In this embodiment, the two ends of the propellant column 8 are respectively cut by the two sawing discs 51. The distance between the two sawing discs 51 is the length required for cutting the propellant column 8, which can ensure that the length of the propellant column 8 meets the preset requirements, ensure the cutting quality of the propellant column 8, and improve the processing accuracy of the propellant column 8.

[0047] Under the pushing action of the telescopic driving member 4, the propellant column 8 can roll to the position of the sawing assembly 5, and the two sawing discs 51 are used to saw both ends of the propellant column 8. During this process, the redundant parts at both ends of the propellant column 8 are effectively cut off, forming waste materials that fall into the waste hopper 16 below through the blanking port 15, meeting the dimensional accuracy requirements of the propellant column 8.

[0048] In a possible implementation manner, please refer to Figures 1 to 8 , a material guiding seat 52 is provided on the frame 1 between the two sawing discs 51. The discharging end of the material guiding seat 52 gradually extends downward and obliquely. A finished product box 7 is provided on the side of the frame 1 at the outlet side of the sawing assembly 5. The finished product box 7 is used to receive the finished products sawn by the sawing assembly 5. A finished product box 7 is provided on the side of the frame 1 at the outlet side of the sawing assembly 5. The finished product box 7 is used to receive the finished products sawn by the sawing assembly 5. The sawn propellant column 8 rolls smoothly into the finished product box 7 under the guiding action of the top surface of the material guiding seat 52, completing the effective collection of the finished products.

[0049] In some embodiments, the driving end of the telescopic driving member 4 is connected with an outstretched pressing arm 41 for pushing the propellant column 8. An avoidance groove 43 is provided on the outstretched pressing arm 41 and runs through from top to bottom to avoid the sawing assembly 5. A downward pressing arc groove 42 is provided on the outer end surface of the outstretched pressing arm 41 and extends to the bottom wall of the outstretched pressing arm 41, and contacts the circumferential wall of the propellant column 8 to limit the propellant column 8.

[0050] In this embodiment, the telescopic driving member 4 is used to drive the outstretched pressing arm 41 to horizontally push outwards. The downward pressing arc groove 42 on the outstretched pressing arm 41 is used to limit the outer peripheral wall of the propellant column 8 and push the propellant column 8 to the position of the sawing assembly 5. The two sawing discs 51 are respectively used to cut both ends of the propellant column 8, so that the redundant lengths at both ends of the propellant column 8 are cut off, meeting the dimensional cutting requirements of the propellant column 8.

[0051] Specifically, when the outstretched pressing arm 41 is used to push the propellant column 8 forward, the propellant column 8 rolls and is subjected to the sawing action of the sawing disc 51. In order to avoid position interference between the sawing disc 51 and the outstretched pressing arm 41, two avoidance grooves 43 that run through from top to bottom are provided on the outstretched pressing arm 41. The two avoidance grooves 43 extend perpendicular to the circumferential direction of the sawing disc 51 and are arranged in one-to-one correspondence with the two sawing discs 51. While meeting the requirement of pushing the propellant column 8, it can also avoid position interference with the sawing disc 51.

[0052] The above-mentioned propellant grain length processing device uses the lifting push arm 2 under the frame 1 to push the single propellant grain 8 in the feeding hopper 6 upward in sequence, so that the single propellant grain 8 is removed from the feeding hopper 6 and transferred to the supporting strip seat 11. The translation push rod 3 horizontally pushes the propellant grain 8 on the supporting strip seat 11 to be separated from the supporting strip seat 11, and then uses the telescopic driving part 4 to push the peripheral wall of the propellant grain 8, so that the propellant grain 8 rolls to the position of the sawing assembly 5, and the two ends of the propellant grain 8 are cut by the sawing assembly 5 to make the propellant grain 8 meet the length requirement. The above device realizes the cutting of the length of the propellant grain 8, improves the processing efficiency of the propellant grain 8, and eliminates potential safety hazards.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
