A method of decomposing a projectile decomposing line, the method comprising:
the first step, feeding, which is specifically as follows:
the shell is inserted into the rotary discharging head by manpower at the feeding station, and the shell is rotated until the rotary discharging clamping bamboo shoots are automatically pinned into the mounting holes of the fuze; therefore, the rotary disassembling head realizes axial limit and circumferential limit; when the axial limiting is performed, the limiting plate axially positions the first limiting pin, so that the rotary disassembling shaft sleeve is positioned at the left limit, the right end face of the rotary disassembling head cannot move rightwards due to the limitation of the rotary disassembling shaft sleeve, and the axial limiting of the rotary disassembling head is ensured; when in circumferential limit, the locking ring is connected with the rotary disassembling head through a locking ring pin, the right end face of the locking ring is attached to the rotary disassembling shaft sleeve in the initial state, and the rotary disassembling shaft sleeve is restrained by the first limiting pin to axially move but not rotate, so that the rotary disassembling head cannot rotate; completing the position positioning of the shell on the shell conveying trolley;
Secondly, pulling out the bullet and pouring the medicine, which is specifically as follows:
the bullet conveying trolley is sent to a bullet pulling and pouring station through a station switching mechanism; then, carrying out a process of pulling out the bullet and pouring the medicine;
firstly, a pulling manipulator is driven by a hydraulic rod to extend forwards, a claw of the pulling manipulator is blocked by a bottom edge of the bullet, and the claw is opened under the action of a claw chamfering inclined plane; then, after the manipulator advances to the right limit position, the manipulator starts to retreat, the clamping jaw clamps the bottom edge under the action of spring force, and the cartridge is continuously retreated to be pulled out; then, the bullet pulling manipulator continues to retreat, the rotating body idler wheel is blocked by the rotating body stop iron, the claw seat is pushed to rotate clockwise with the claw and the cartridge case until the rotating body idler wheel enters below the rotating body stop iron, at the moment, the opening of the cartridge case is exactly vertical downwards, the hydraulic rod stops retreating, and the medicine in the cartridge case is poured out under the action of gravity; when the copper removing agent sheet is arranged in the cartridge, the needle below the opening of the cartridge is pushed by the hydraulic cylinder to pierce the celluloid sheet upwards, and then the celluloid sheet is pulled out downwards, so that the medicine in the cartridge can be poured out smoothly; the poured propellant powder slides out to a material receiving box along a material channel; then, the hydraulic rod continuously drives the mechanical arm to retreat, when the medicine cartridge passes through the medicine-emitting channel, the upper parts of the clamping jaws are blocked by the clamping jaw retaining iron, the clamping jaws are opened, the medicine cartridge falls down under the action of gravity and is discharged along the slideway; the mechanical arm stops backing at the position where the clamping jaws are fully opened; the hydraulic rod drives the mechanical arm to advance, and under the action of the claw compression spring and the torsion spring, the claw and the claw seat recover to an initial state in sequence and enter the next cycle;
Thirdly, the fuze is unloaded in a rotating way, which is as follows:
in the preparation process, a bullet conveying trolley moves from a bullet pulling and pouring station to a rotary unloading fuze station, and a limiting plate on the trolley is pushed to the right end by a limiting plate fixing baffle plate, so that the axial constraint of the retreating of the rotary unloading shaft sleeve is relieved; after the bullet conveying trolley reaches the station of the rotary unloading fuze, the hydraulic cylinder drives the pressure head to compress the bullet;
the main shaft in the main shaft box extends forwards, and after the pull claw passes over the unidirectional end face jaw clutch on the spin-release shaft, the pull claw is combined with the clutch of the spin-release shaft; the spindle stops advancing and starts rotating, the fuze thread pushes the spindle to retreat in the screwing-off process, when the fuze thread is completely unscrewed, the spindle actively retreats, the pulling claw drags the screwing-off shaft to thoroughly separate the fuze from the projectile, when the pulling claw retreats into the stop iron sleeve, the pulling claw is opened under the action of the stop iron sleeve, the spindle continuously retreats, and the spindle is thoroughly separated from the screwing-off shaft;
the detonator is not exposed in the process of screw unloading, after the pressure head compresses the projectile, the screw unloading shaft moves leftwards under the thrust action of the main shaft in the main shaft box, the screw unloading shaft drives the locking ring to move leftwards until contacting with the shaft shoulder of the screw unloading head, at the moment, the locking surface wedges the unlocking lever, after the locking ring moves leftwards, the locking ring is separated from the screw unloading shaft sleeve, and the locking plate and the unlocking plate are respectively ejected outwards leftwards under the action of spring force until entering a mutual clamping state; the spindle drives the rotary detaching shaft to start rotating, and the rotary detaching fuze; when the length of the screw out of the fuze is enough, the drawing clamping bamboo shoots are clamped into the end face of the fuze under the action of spring force, and when the number of turns of the screw-out reaches a specified value, the rotation is stopped, and the spindle hydraulic cylinder drags the spindle to drive the screw-out shaft to retreat;
The bullet is automatically blanked, when the hydraulic cylinder drives the pressure head to downwards press the bullet, the lower hook body on the blanking plate forces the upper hook body to swing clockwise, and when the upper hook body passes over the bending, the plumb state is restored under the action of gravity; when the pressure head is lifted upwards to a certain height, the upper hook body lifts the blanking plate, the blanking plate lifts one end of the pellet, the pellet slides out of the pellet conveying trolley leftwards and downwards under the action of gravity and falls into the material channel, and automatic blanking of the pellet is completed; a gap is reserved between the blanking hook and the blanking plate bending, and the blanking plate descends under the action of gravity to restore to the original position;
fourth, the station of unloading, it is as follows specifically:
the unloading station is used for manually unloading the fuze with the exposed detonator, and the station is in idle operation when the fuze with the exposed detonator is not used; when the fuze with the exposed detonator is unloaded, the fuze exposed by the detonator is manually taken out; when the fuse is taken out, the unlocking lever on the rotary unloading head is pressed, the rotary unloading clamping bamboo shoots clamped in the fuse mounting holes are pulled out, and the fuse can be taken out.
Further, before the fuse with the exposed detonator is disassembled, the unlocking ring is rotated by an angle, and then the right end is pushed and positioned by a set screw; the spin-unloading step is the same as spin-unloading of the detonator fuze without exposure.
Compared with the prior art, the shell decomposing line has the following advantages:
1. the automatic decomposition of the projectile and the fuze and the automatic blanking are realized;
2. the automatic blanking and the manual fuse taking out can be realized, and the two working modes are convenient to switch;
3. the fuse is disassembled by the fuse mounting hole, and a mechanism for preventing the disassembling pin from sliding out is designed, so that the disassembling pin can be prevented from sliding out of the fuse body;
4. the forced drawing mechanism is designed, and when the last few threads of the fuze are damaged and can not be completely discharged, the fuze can be forcedly separated from the projectile;

fourth, the station of unloading, it is as follows specifically:
the unloading station is used for manually unloading the fuze with the exposed detonator, and the station is in idle operation when the fuze with the exposed detonator is not used; when the fuze with the exposed detonator is unloaded, the fuze exposed by the detonator is manually taken out; when the fuse is taken out, the unlocking lever on the rotary unloading head is pressed, the rotary unloading clamping bamboo shoots clamped in the fuse mounting holes are pulled out, and the fuse can be taken out.
5. The decomposition method of claim 4, wherein: before the fuse with the exposed detonator is disassembled, the unlocking ring is rotated by an angle, and then the right end is pushed and positioned by a set screw; the spin-unloading step is the same as spin-unloading of the detonator fuze without exposure.
