Description
Technical field
The invention belongs to ammunition disposal equipment technical field, be specifically related to a kind ofly cut and revolve method for dismounting for the ammunition pressure ring in shrapnel marble disassembling system.
Background technology
The pressure ring of shrapnel bullet is to be threaded connection structure to be connected on bullet shell case inwall. In bullet production process, before pressure ring being rotatably connected in to bullet shell case inwall, need to smear bonded adhesives at the outer surface of pressure ring, relend the draw-in groove application of force on pressing aid ring inwall, make pressure ring screw in bullet shell case inwall, thus, by be threaded and glue connect two kinds of connected modes ensure the fastness being connected between pressure ring and shell case inwall. Also this duplex connecting structure that is threaded and is connected with glue just, makes in the during Destruction of shrapnel bullet, and it is very difficult that the unloading process of pressure ring becomes. On the one hand, need will revolve the instrument that moves back and aim at two draw-in grooves and could implement to revolve deactuate work, this searching position fixing process is more loaded down with trivial details, is not easy to realize mechanized operation. On the other hand, very firm because of its connection, need very powerful amount just it can be taken apart by revolving the mode of moving back, therefore revolve in the process of moving back and can occur revolving the situation of moving back tool slippage because draw-in groove notch is too shallow, cause dismantling unsuccessfully.
Summary of the invention
Object of the present invention is just to provide a kind of ammunition pressure ring and cuts and revolve method for dismounting, dismantles difficult technical problem to solve pressure ring in prior art.
The present invention is achieved in that
Ammunition pressure ring is cut and is revolved method for dismounting, comprises the steps:
A. arrange and cut lathe turner's tool:
One tool rest with hollow cavity is set; Below described tool rest, by securing member linking springs seat, described spring base is offered the endoporus with reducing shoulder; On tool rest, rotate knife bar is installed by knife bar bearing pin symmetrically; The cylindrical void in a certain angle with axis offered at each knife bar middle part symmetrically; Make the top of each knife bar stretch out tool rest at right angle setting cone cutter; One pull bar is set, and top is equipped with and is opened bearing pin, described in open bearing pin successively through the cylindrical void on described knife bar; Make pull bar bottom stretch out described spring base the nut that is spirally connected, on the pull bar between described nut and described spring base, be socketed butterfly spring;
B. the shrapnel bullet clamping that removes fuse is fixed;
C. adjusting nut position to butterfly spring pretightning force meets the requirements;
D. make tool rest reach, make the cone cutter of knife bar front end enter pressure ring internal cavity;
E. make to move after pull bar, two knife bars are opened as rotating shaft is outwards scissor-shaped taking knife bar bearing pin separately, make to bore cutter tensioner and point of a knife incision pressure ring inwall;
F. make tool rest revolve and move back, drive pressure ring to revolve and move back or pressure ring inwall is cut and revolved destruction.
In said method, described cone cutter is Rhizoma Sparganii tapered knife, is connected on described knife bar by bearing pin.
Method of the present invention is moved after by pull bar, can make knife bar open, and cone cutter tensioner is also cut pressure ring inwall. Make again tool rest drive knife bar rotation, and then realize smoothly revolving of pressure ring moved back or its wall body is carried out to destructive object of removing. By precession or the pretightning force of revolving withdrawing nut position and adjust butterfly spring, bore the crush-cutting power of cutter to pressure ring inwall thereby adjust when knife bar opens, to adjust the knife edge of pyramid cutter to the incision degree of pressure ring inwall, guarantee not in the process of moving back, to occur slippage revolving. Meanwhile, the present invention adopts tapered knife, has both been conducive to the incision to pressure ring inwall, also for avoiding slippage that further guarantee is provided.
The method that the present invention bores cutter incision wall body by design avoids utilizing in prior art the loaded down with trivial details course of work of the searching contraposition that existing draw-in groove brings, solved the technical problem that is easy to slippage occurring in more shallow the brought unloading process of existing draw-in groove notch simultaneously, can realize the mechanization of pressure ring and remove, thereby greatly improve operation work efficiency.
Brief description of the drawings
Fig. 1 is that in the present invention, ammunition pressure ring is cut the sectional structure chart that revolves extracting tool.
Fig. 2 is that in the present invention, ammunition pressure ring is cut the side diagram of revolving extracting tool.
Detailed description of the invention
Below in conjunction with accompanying drawing, most preferred embodiment of the present invention is described in further details.
Ammunition pressure ring of the present invention is cut and is revolved method for dismounting and comprise the steps:
A. with reference to shown in figure 1,2, ammunition pressure ring is set and cuts and revolve extracting tool:
Ammunition pressure ring is cut and is revolved extracting tool and comprise tool rest 3, spring base 9, the first knife bar bearing pin 5, the second knife bar bearing pin 10, the first knife bar 2, the second knife bar 11, pull bar 6, nut 8 and butterfly spring 7. Wherein, tool rest 3 is for having the pedestal of hollow cavity. Below pedestal, be connected with spring base 9 by securing member. In spring base 9, have the endoporus 15 with reducing shoulder, reducing shoulder is as limited step. The first knife bar bearing pin 5 and the second knife bar bearing pin 10 symmetries, be installed on tool rest 3 rotationally. The first knife bar 2, taking the first knife bar bearing pin 5 as rotating shaft, is installed in the hollow cavity of tool rest 3.
