Detailed implementation manners

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Generally, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0030] As Figures 1 to 17As shown in the figure, the specific structure of a bullet disassembling machine with different calibers of the present utility model is as follows: A table board 35 is provided on an operating table 1 with a table type structure. The operating table 1 is surrounded by a first front enclosure board 3, a second front enclosure board 4, side enclosure boards 8 and a rear enclosure board 2 to form a box type structure. A connecting seat 34 is installed on the table board 35, and the connecting seat 34 is located at the center position of the table board 35. The upper end of the connecting seat 34 is connected to a rotating seat 16, and the rotating seat 16 is rotatable. The lower end of the connecting seat 34 is connected to a motor speed reducer 31, and the motor speed reducer 31 extends into the interior of the operating table 1. The left and right sides of the rotating seat 16 are respectively connected to a first mold and a second mold through connecting rods 14. The first mold includes a first upper mold 10 and a first lower mold 11. A first bullet path adapted to the external dimension of the bullet is provided between the first upper mold 10 and the first lower mold 11. The first bullet path includes a straight section and an expanding section. The diameter of the straight section is 16 mm, and the diameter of the expanding section expands from 20 mm to 24 mm. The second mold includes a second upper mold 17 and a second lower mold 18. A second bullet path adapted to the external dimension of the bullet is provided between the second upper mold 17 and the second lower mold 18. The second bullet path includes a straight section and an expanding section. The diameter of the straight section is 18 mm, and the diameter of the expanding section expands from 28 mm to 30 mm. The first mold and the second mold are slidably connected to the table board 35. A pressing plate assembly 9 is installed on the first mold and the second mold. The pressing plate assembly 9 is fixed on the table board 35 and cannot be moved. The function of a stop block 13 is to fix the pressing plate assembly 9 to ensure that the pressing plate assembly 9 will not move with the movement of the fixture. A pressing rod 21 is fixed to the pressing plate assembly 9 with an M12 nut 29. Taking the M12 nut 29 as an axis, the bullet is lifted and placed in, and then put down to press the bullet pellet part. After disassembly, the pressing rod 21 is lifted to remove the pellet. Moreover, the pressing plate assembly 9 is fixedly connected to the table board 35, and the pressing rod 21 is connected to the pressing plate assembly 9. Semi-nut structures of an M16 nut 12 and an M20 nut 19 are respectively welded to the bottom of the long rods of the two groups of pressing rods 21, and are buckled with semi-nut structures of another M16 nut 12 and an M20 nut 19 welded at corresponding positions on the table board 35 to form a complete nut structure. Two groups of switch brackets 15 are arranged on the table board 35 in a staggered manner, and proximity switches 32 are arranged on the switch brackets 15 for limiting the connecting rod 14. Two groups of blanking ports 36 are symmetrically opened on the table board 35. The first mold and the second mold are correspondingly installed on the blanking ports 36, and drawers 2 are correspondingly installed below. An electric control box 6 is arranged below the operating table 1, and a foot pedal box 5 is arranged below the electric control box 6. A pedal switch 33 is arranged in the foot pedal box 5.

[0031] The bullet disassembling machine is processed with 10-mm thick steel plates and has a certain fire and explosion prevention ability. This utility model uses 10-mm thick steel plates, which can withstand the combustion and explosion hazards caused by the accidental ignition of the propellant in 14.5-mm and 12.7-mm bullets, and can ensure the safety of the operators, internal components and electrical circuits of the equipment to a certain extent. Two sets of ammunition disassembling and removing fixtures are installed on the 35th surface of the table board of the bullet disassembling machine, which are respectively applicable to the calibers of 14.5 mm and 12.7 mm. The selection of the fixture size is determined according to the sizes of the two-caliber bullets. The bullets are placed in the fixtures to achieve clearance fit. After disassembly, the cartridge cases can automatically fall into the drawers without manual operation for the disassembly operation of the bullets. Two drawers 2 made of copper are installed inside the bullet disassembling machine to catch the disassembled cartridge cases and the gunpowder scattered inside. The copper material has the ability to prevent static electricity, preventing static electricity generated by collision and friction during the disassembly process of the ammunition from causing the gunpowder to ignite and burn, resulting in casualties. The driving device of the bullet disassembling machine uses a motor reducer 31. By supplying power to the motor reducer 31, power is generated to drive the rotating seat 16 in the middle of the 35th surface of the table board. The rotating seat 16 rotates clockwise (forward rotation), driving the connecting rod to move. Semi-nut structures of M16 nuts 12 and M20 nuts 19 are respectively welded under the long rod positions of the two groups of connecting rods 14, forming an integral nut with the semi-nut structures of M16 nuts 12 and M20 nuts 19 respectively welded at the positions of the bottom semi-nuts of the corresponding connecting rods 14 on the table board 35. The bullet passes through the nuts of the above two structures and is manually limited. Driven by the rotating seat 16, it moves towards the central axis position of the table board 35, driving the fixture to move towards the central axis position of the table board 35 to achieve the disassembly of the ammunition. A switch bracket 15 is installed on the table board 35 of the bullet disassembling machine. A sensor is behind the switch bracket 15. The sensor lead wire is led out through the opening on the table board 35. The proximity switch 32 is connected to the switch bracket 15. The two groups of switch brackets 15 are arranged with relative misalignment. The proximity switch 32 realizes the limiting function when the connecting rod 14 moves towards the outside of the table board 35 during the counterclockwise rotation of the rotating seat 16, preventing over-travel movement and causing damage to the bullet disassembling machine.

[0032] Operating steps of the bullet disassembling machine:

[0033] 1. Push the power-on switch. The power-on switch is on the operation panel of the electric control box 6. The green button is for on, the red button is for off, and the large button is the emergency stop button to power on the bullet disassembling machine;

[0034] 2. Place the ammunition to be disassembled in the fixture on the 35th surface of the table board;

[0035] 3. Use the pressure rod 21 on the 35th surface of the table board to press the bullet part of the ammunition;

[0036] 4. Step on the operating foot pedal, i.e., the foot switch 33 in the foot box, the motor reducer 31 rotates, driving the rotating seat 16 in the middle of the console board 35 to rotate clockwise (forward rotation). The connecting rod 14 drives the fixture to move along the slide towards the center of the board 35. At this time, the ammunition projectile part is pressed and held stationary by the pressure rod 21. The long rod position of the pressure rod 21 includes the cartridge case part which is limited by the fixture. The conical surface of the cartridge case forms a mating relationship with the conical surface of the fixture. When the fixture moves towards the center of the board 35, the projectile is pressed and fixed by the pressure rod 21, and the conical surface of the cartridge case is driven by the conical surface of the fixture to move towards the center of the board 35. The fixture exerts an axial separation force on the cartridge case. When the separation force is greater than the bonding force between the cartridge case and the projectile, the cartridge case and the projectile are separated, and the cartridge case and the gunpowder fall into the drawer made of copper material;

[0037] 5. Loosen the handle pressing the projectile, remove the projectile, and take out the cartridge case and gunpowder from the drawer;

[0038] 6. Step on the operating foot pedal, and the turntable in the middle of the console board 35 rotates counterclockwise (reverse rotation) to reset the fixture and prepare to operate and disassemble the next projectile;

[0039] 7. After the operation is completed, turn off the power supply.

[0040] The utility model realizes the purpose of disassembling different caliber bullets with one device, and can disassemble and remove them quickly, safely, efficiently and securely. The bullet disassembling machine has the characteristics of light weight and miniaturization, which is convenient for disassembly and installation. The internal structure of the bullet disassembling machine is simple, with good maintainability, supportability and environmental adaptability. Its structural parts and electrical parts are all replaceable, and the tooling fixture can be quickly replaced. At the same time, the device has an electrostatic grounding device, which improves the safety of the ammunition disassembly and removal process. The advantage of the utility model is that it can disassemble and remove the projectile without damaging the structure of the bullet, so as to realize the recycling of the disassembled projectile and cartridge case.

[0041] The key of the utility model is how to realize the safe disassembly and removal of bullets. The disassembly and removal of bullets need to apply a certain axial force to the bullets to reach and exceed the mating force between the projectile and the cartridge case, so as to realize the disassembly and removal of bullets. By setting the reducer, a control signal is provided to the motor reducer 31 by controlling the foot pedal. Then, the motor reducer 31 drives the rotating seat 16 to rotate, driving the connecting rod 14, and converting the angular velocity of the rotation of the rotating seat 16 into the linear velocity of the movement of the fixture along the slide, so as to provide an axial separation force for the ammunition and realize the disassembly of the ammunition.
