Abstract
The utility model discloses a large-caliber armor-piercing bullet core which relates to the technical field of bullets. The large-caliber armor-piercing bullet core comprises a cylindrical bullet core body, wherein a bullet core head is arranged on the top end of the bullet core body, the bullet core head is composed of a conical tip cone and a truncated cone-shaped second tap connected to the lower part of the tip cone, the tip cone, the second tap and the bullet core body are integrally formed, and a tail hole is formed in the bottom of the bullet core body and used for filling tracer compositions and burning materials. The large-caliber armor-piercing bullet core has the beneficial effects that the structure design of the large-caliber armor-piercing bullet core is favorable for keeping the complete shape of the bullet core body in an armor-piercing process without breaking and increasing the armor-piercing rate of the bullet core, and additionally, the tail hole is designed for the tail cone and can be used for filling the tracer compositions and the burning materials, so that the large-caliber armor-piercing bullet core has an armor-piercing function and explosion and burning functions.
Description
[technical field]
The utility model relates to a kind of bullet, relates in particular to a kind of heavy caliber armor-piercing bullet core.
[background technology]
The bullet of present gun is mainly to utilize gunpowder explosion to produce the principle of thrust, bullet structure is by plastic material, to make shell by playing core, be assembled in the shell case that gunpowder is housed, when gunlock, pull the plate machine, sub warhead is launched by the thrust that gunpowder explosion produces in bore.
Play core and play an important role in the performance of bullet, the material property that plays core can effectively improve the armor-penetrating ability of bullet.Traditional bullet core adopts steel to make material, therefore the kinetic energy aspect that plays core is difficult to reach the armour-piercing requirement of heavy caliber bullet, particularly, for the bullet of 12.7mm and 14.5mm bore, reach the desired armor-piercing action of bullet, adopt traditional bullet core material substantially can't realize.Because the corresponding target plate thickness that will puncture of big caliber ammunition core, angle and distance all more small-bore bullet core have significantly and to improve, difficulty is more large, and target plate thickness is thicker, and angle is larger, and distance is farther, institute for also difference of Operation Target.The big caliber ammunition core, except having the armour-piercing function, can also have blast and combustion function simultaneously, and this is to be difficult to realize on small-bore bullet core.And traditional steel bullet core adopts mach method to process, and its processing cost is higher, and difficulty of processing is larger, and adopts steel bullet core to require the gun barrel gun pressure higher, and the wearing and tearing that can increase like this gun reduce gun service life.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, and a kind of heavy caliber armor-piercing bullet core with armor-piercing action is provided.
The technical solution of the utility model is achieved in that it includes columniform bullet core body, in described bullet core body top, be provided with the bullet core head, its improvements are: described bullet core head is by conical addendum cone and be connected to the addendum cone bottom, the plug tap that is truncated cone-shaped forms, described addendum cone, plug tap and to play core body one-body molded; The bottom of described bullet core body also is provided with a uropore, be used to loading tracer mixture and incendiary material;
Preferably, the afterbody of described bullet core body is inverted truncated cone-shaped, is called tail cone, and above-mentioned uropore namely is arranged in tail cone;
Preferably, described uropore plays core body inside by in tail cone, extending to, and this uropore is cylindrical;
Preferably, described bullet core head, bullet core body and tail cone all adopt carbide alloy or tungsten alloy to make;
Preferably, the density of described carbide alloy is 14.5-14.6g/cm
3, hardness is 88.0-90.0HRA;
Preferably, the bus of described addendum cone and the bus and the angle that play core body center line of the angle that plays the core body center line less than plug tap.
The beneficial effects of the utility model are: bullet core head of the present utility model adopts addendum cone and plug tap to form, being designed with of this structure has been beneficial to the armour-piercing process core body of being hit by a bullet and kept shape complete, in the armour-piercing process, do not occur broken, plug tap is conducive to reduce the armour-piercing resistance, be conducive to improve bullet core armour-piercing rate, in addition, tail cone has designed a uropore, can be used to load tracer mixture and incendiary material, thereby realize the function of blast and burning; Play core body and adopt powder metallurgy process to carry out production and processing, make production efficiency improve, processing cost reduces, and is conducive to play the batch production of core body.
[accompanying drawing explanation]
Fig. 1 is cross section view of the present utility model.
[specific embodiment]
The utility model will be further described below in conjunction with drawings and Examples.
with reference to shown in Figure 1, the utility model has disclosed a kind of heavy caliber armor-piercing bullet core, this heavy caliber armor-piercing bullet core comprises columniform bullet core body 10, the top that plays core body 10 is and plays core head 20, in the present embodiment, play core head 20 by conical addendum cone 201 and be connected to addendum cone 201 bottoms, the plug tap 202 that is truncated cone-shaped forms, addendum cone 201, plug tap 202 and bullet core body 10 adopt powder metallurgy process one-body molded, in addition, the afterbody that plays core body 10 is inverted truncated cone-shaped, be called tail cone 101, tail cone 101 bottoms also are provided with a uropore 102, this uropore 102 is extended to and is played core body 10 inside by tail cone 101 bottoms, uropore 102 is cylindrical, uropore 102 is interior be used to loading tracer mixture and incendiary material, therefore when realizing the armour-piercing function, also have blast and combustion function.
In the present embodiment, the bus of addendum cone 201 and the bus and the angle that play core body 10 center lines of the angle that plays core body 10 center lines less than plug tap 202, being designed with of this structure has been beneficial to the armour-piercing process core body 10 of being hit by a bullet and kept shapes complete, in the armour-piercing process, do not occur broken, plug tap 202 is conducive to reduce the armour-piercing resistance, is conducive to improve the core armour-piercing rate that plays; Play core head 20, bullet core body 10 and tail cone 101 and all adopt carbide alloy to make, the density of carbide alloy is 14.5-14.6g/cm
3, hardness is 88.0-90.0HRA, adopts carbide alloy to make, and makes bullet core body 10 after launching gun barrel, have higher kinetic energy, thereby has the energy of armour-piercing.Carbide alloy has higher hardness, in the armour-piercing process, reduced to play the deformation quantity of core body 10, thereby in the armour-piercing process, reduce the loss of energy, carbide alloy has higher hardness with respect to steel plate again, in punching armour-piercing process, easily cause the deformation of steel plate, thereby realize the armour-piercing function of bullet.The employing powder metallurgy process that plays core body carries out production and processing, makes production efficiency improve, and processing cost reduces, and is conducive to play the batch production of core.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, various distortion and modification can appear, the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
