Abstract
The invention discloses a gun perforation bullet which comprises a bullet case. A metal explosive type cover is arranged inside the bullet shell, and a primary explosive layer is arranged between the metal explosive type cover and the inner wall of the bullet shell. A bullet cover is buckled at the front end of the bullet shell, a high-energy explosive cake is coaxially arranged at the inner side of the bullet cover, and a through hole penetrates through the middle of the high-energy explosive cake. During the working process, impact wave generated after the primary explosive layer is exploded crushes the metal explosive cover and forms a metal jet high in temperature, pressure and speed, the metal jet passes through the through hole and penetrates the bullet cover, then the metal jet sequentially penetrates through a gun barrel, a sleeve and a ground layer; meanwhile the impact wave explodes the high-energy explosive cake into micro particles, the micro particles enter the ground layer along perforation ducts generated by the metal jet, and then explosion occurs so as to achieve the effect that perforation holes create seams. The gun perforation bullet is simple in structure, relatively low in assembly difficulty and high in production efficiency. The perforation depth is large, and the perforation effect is good.
Description
Technical field
The present invention relates to mining construction corollary equipment technical field, particularly a kind of perforating bullet.
Background technology
In current mine construction exploration work progress, perforating bullet is a kind of very common new well development and old well Counterboring apparatus, and along with improving constantly of user demand, people also have higher requirement to the performance of perforating bullet.
Current existing perforating bullet, its normally on conventional body basis in rifle or rifle increase high energy material outward, the high energy material that ignites while utilizing perforation, produces high temperature and high pressure gas, thereby eliminate nearly well, pollutes, and pressure break is carried out in stratum simultaneously.Yet although this kind of perforating bullet can meet basic construction needs, because its assembly technology is complicated, production efficiency is lower, and its perforating depth is not enough, perforating effect is poor.
Therefore the production efficiency and the perforating effect thereof that, how to improve perforating bullet are the important technological problems that those skilled in the art need to solve at present.
Summary of the invention
The object of this invention is to provide a kind of perforating bullet, the production efficiency of this perforating bullet is higher, and its perforating effect is better.
For solving the problems of the technologies described above, the invention provides a kind of perforating bullet, comprise shell case, the inside of described shell case is provided with metal liner, is provided with main explosive layer between the inwall of described metal liner and described shell case;
The front end of described shell case fastens bullet lid, and the inner side of described bullet lid is coaxially arranged with high energy medicine cake, and the middle part of described high energy medicine cake is coaxially penetrated with through hole.
Preferably, the axial cross section of described high energy medicine cake is circular arc, and its center of circle, cross section be positioned at described high energy medicine cake the extended line of axis near described shell case place one side on.
Preferably, on the leading section outer peripheral face of described shell case, have draw-in groove, the rear portion of described bullet lid has the buckle coordinating with described draw-in groove clamping.
Relative above-mentioned background technology, perforating bullet provided by the present invention, comprises shell case, the inside of described shell case is provided with metal liner, is provided with main explosive layer between the inwall of described metal liner and described shell case; The front end of described shell case fastens bullet lid, and the inner side of described bullet lid is coaxially arranged with high energy medicine cake, and the middle part of described high energy medicine cake is coaxially penetrated with through hole.In the course of work, crush described metal liner form high temperature, high pressure, metal jet at a high speed of the shock wave that described main explosive layer produces after igniting, this metal jet is through described through hole and penetrate described bullet lid, penetrate successively afterwards gun barrel, sleeve pipe and stratum, shock wave explodes into molecule by described high energy medicine cake simultaneously, the perforated hole road that these molecules produce along metal jet enters stratum, and then detonation is made seam texts to reach perforation.Described perforating bullet simple in structure, assembly difficulty is lower, and production efficiency is higher; And its perforating depth is larger, and perforating effect is better.
In another preferred version of the present invention, the axial cross section of described high energy medicine cake is circular arc, and its center of circle, cross section be positioned at described high energy medicine cake the extended line of axis near described shell case place one side on.The described high energy medicine cake with this kind of circular section structure can maximize the interior height of burst that improves described metal liner, guarantees that the jet of described metal liner stretches as far as possible, thereby makes it wear that to penetrate the degree of depth larger, and makes the perforating effect of described perforating bullet better.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The assembly structure sectional view of the perforating bullet that Fig. 1 provides for a kind of specific embodiment of the present invention.
The specific embodiment
Core of the present invention is to provide a kind of perforating bullet, and the production efficiency of this perforating bullet is higher, and its perforating effect is better.
In order to make those skilled in the art person understand better the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, the assembly structure sectional view of the perforating bullet that Fig. 1 provides for a kind of specific embodiment of the present invention.
In the specific embodiment, perforating bullet provided by the present invention, comprises shell case 11, and the inside of shell case 11 is provided with metal liner 111, is provided with main explosive layer 112 between the inwall of metal liner 111 and shell case 11; The front end of shell case 11 fastens bullet lid 12, and the inner side of bullet lid 12 is coaxially arranged with high energy medicine cake 121, and the middle part of high energy medicine cake 121 is coaxially penetrated with through hole 122.In the course of work, crush metal liner 111 form high temperature, high pressure, metal jet at a high speed of the shock wave that main explosive layer 112 produces after igniting, this metal jet is through through hole 122 penetrating projectile lid 12, penetrate successively afterwards gun barrel, sleeve pipe and stratum, shock wave explodes into molecule by high energy medicine cake 121 simultaneously, the perforated hole road that these molecules produce along metal jet enters stratum, and then detonation is made seam texts to reach perforation.Described perforating bullet simple in structure, assembly difficulty is lower, and production efficiency is higher; And its perforating depth is larger, and perforating effect is better.
Further, the axial cross section of high energy medicine cake 121 is circular arc, and its center of circle, cross section be positioned at high energy medicine cake 121 the extended line of axis near shell case 11 place one sides on.The high energy medicine cake 121 with this kind of circular section structure can maximize the interior height of burst that improves metal liner 111, guarantees that the jet of metal liner 111 stretches as far as possible, thereby makes it wear that to penetrate the degree of depth larger, and makes the perforating effect of described perforating bullet better.
