Description
Technical field
The utility model relates to the bullet production technical field, relates in particular to a kind of powder metallurgy that is applicable to and produces the Armour-Piercing Reduced core in batches.
Background technology
The bullet of present gun mainly is to utilize gunpowder explosion to produce the principle of thrust; The bullet structure is to make shell through playing core by plastic material; Be assembled in the shell case that gunpowder is housed, when gunlock is pulled the plate machine, sub warhead is launched by the thrust that gunpowder explosion produces in bore.
Play core and in the performance of bullet, play an important role, the material property that plays core can effectively improve the armor-penetrating ability of bullet, and traditional bullet core adopts steel to make material; Therefore the hardness, the kinetic energy aspect that play core are difficult to reach the armour-piercing requirement of small caliber bullet, particularly for small-bore bullet, reach the desired armor-piercing action of bullet; Adopt traditional bullet core material can't realize basically, traditional steel bullet core adopts mach method to process, and its processing cost is higher; Difficulty of processing is bigger; And adopt steel bullet core to require the gun barrel gun pressure higher, the wearing and tearing that can increase gun like this reduce gun service life.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned technology, provides a kind of and can reach the Armour-Piercing Reduced core that armor-piercing action, processing cost are low, help producing in batches.
The technical scheme of the utility model is achieved in that it comprises the bullet core head and plays core body, and its improvements are: said bullet core head is made up of nose cone and plug tap, and its nose cone is a conical structure, and plug tap is the conical structure of the no vertex of a cone; The angle of the center line of the bus of said nose cone and bullet core body is less than the bus of plug tap and the angle of the center line that plays core body; Said nose cone, plug tap and bullet core body connect to form this Armour-Piercing Reduced core; Said bullet core body is a carbide alloy with the material that plays core head;
In the said structure, the density of said carbide alloy is 14.50g/cm3-14.60g/cm3;
In the said structure, the Rockwell hardness of said carbide alloy is 88.0-90.0;
In the said structure, said bullet core body is a cylindrical structure.
The beneficial effect of the utility model is: the bullet core head of one of which, the utility model is made up of nose cone and plug tap; Nose cone is a conical structure, and plug tap is circular bucking ladder structure, and the angle of the center line of the bus of nose cone and bullet core body is less than the bus of plug tap and the angle of the center line that plays core body; Nose cone helps the armour-piercing process core of being hit by a bullet and keeps shape intact; Fragmentation does not take place in the armour-piercing process, and plug tap helps reducing the armour-piercing resistance, helps improving bullet core armour-piercing technical indicator; Two, playing core head all has highdensity carbide alloy to process with the bullet core body; Make that playing core has higher kinetic energy after launching gun barrel, thereby have the energy of armour-piercing, and in the armour-piercing process, reduced to play the deformation quantity of core; Reduce the loss of energy; The carbide alloy of high rigidity has higher hardness with respect to steel plate, in punching armour-piercing process, causes the deformation of steel plate easily, thereby realizes the armour-piercing function of bullet; Three, the utility model adopts powder metallurgy process to carry out production and processing, makes production efficient improve, and processing cost reduces, and helps playing the batch process of core.
Description of drawings
Fig. 1 is the utility model front view.
Among the figure: play core head 1; Play core body 2; Nose cone 11; Plug tap 12; Play the center line 3 of core body.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
With reference to shown in Figure 1, the utility model has disclosed a kind of Armour-Piercing Reduced core, and it is an embodiment of the utility model, and it comprises bullet core head 1 and play core body 2 that playing core body 2 is cylindrical structure; Said bullet core head 1 is made up of nose cone 11 and plug tap 12, and nose cone 11 is a conical structure, and plug tap 12 is the conical structure of the no vertex of a cone; The angle of the center line 3 of the bus of said nose cone 11 and bullet core body is less than the bus of plug tap 12 and the angle of the center line 3 that plays core body; Said nose cone 1, plug tap 12 and play core body 2 and connect to form this Armour-Piercing Reduced core; Said bullet core body 2 is a carbide alloy with the material that plays core head 1.
According to said structure, and with reference to shown in Figure 1, the utility model bullet core body adopts cylindrical structural; Play core head nose cone and plug tap are set; The angle of the bus of said nose cone and the center line 3 that plays core body is less than the bus of plug tap and the angle of the center line that plays core body, and such design makes nose cone help playing core in the process of armour-piercing, to keep the complete of its shape, be difficult in the process of armour-piercing, taking place fragmentation; Suffered resistance when plug tap helps reducing armour-piercing helps improving the armor-penetrating ability that plays core.
Following table is the utility model main performance table:
According to last table, the utility model has adopted the carbide alloy of high rigidity as the material that plays core, and its density is 14.50g/cm3-14.60g/cm3, and averag density is 14.56 g/cm3; Hardness is Rockwell hardness 89.4-89.9, and average Rockwell hardness is 89.72, with respect to the existing material that adopts steel; Make after the bullet core is launched gun barrel, to have higher kinetic energy, thereby possessed the ability of armour-piercing, simultaneously because the high rigidity of Hardmetal materials; In the process of armour-piercing, reduced the deformation quantity that plays core, thereby reduced the loss of energy, carbide alloy has very high hardness with respect to steel plate; In the armour-piercing process of reality, cause the distortion of steel plate easily, thereby realize the armour-piercing function of this Armour-Piercing Reduced core; In addition, the bending strength of the utility model all has relevant qualification with metallographic structure, and concrete data are with reference to shown in the icon.
The utility model can be according to playing the powder metallurgy pressing mould that the compacting of core dimensioned plays the core shape; Proportionately the branch ratio is carried out the powder preparation with the carbide alloy material; Adopt operations such as powder metallurgy process is suppressed, sintering to process the bullet core that is designed; Make that the processing cost of the utility model is relatively low, production efficiency of products improves, and is of value to the batch process that plays core.
The preferred embodiment that is merely the utility model described above, above-mentioned specific embodiment are not the restrictions to the utility model.In the technological thought category of the utility model, various distortion and modification can appear, and 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.
