Abstract
The utility model relates to an energy accumulating charge, in particular to a multi-level energy accumulating charge which can increase the shaped depth. The utility model adds one level, two levels or more levels of strengthened energy accumulating charge on the existing metallic jet direction of the starting energy accumulating charge with only one metallic charge cover, and the top surface and the bottom surface of the strengthened energy accumulating charge are opened. The multi-level energy accumulating charge enables the explosion to be transmitted stage by stage after detonation. Therefore, the energy of the metallic jet can be compensated continuously. The shaped depth is enhanced obviously. The other advantage of the utility model is that the deferred charge between each level of energy accumulating charge generates backward jet when in explosion to stop a slug after the metallic jet, and the shape or the plug-hole rate of the perforation is reduced.
Description
The utility model relates to a kind of beehive-shaped charge, particularly can improve the multistage beehive-shaped charge of penetration depth.
Existing beehive-shaped charge has only a metal drug-shaped cover, this beehive-shaped charge in use, after the metal jet forward who forms after detonating penetrates target body, along with the carrying out of the process of penetrating, its energy will constantly be consumed.And most energy of follow-up jet can not pass to the forward effectively, thereby jet forward's speed descends rapidly along with the minimizing of energy, drops to zero at last and the broken cover process of termination.The jet that this beehive-shaped charge blast back produces on its direction of advance, preceding sharp point and thin, speed is fast, and the part of back (being the pestle body) is thicker, thereby the resistance that is subjected to is bigger, the degree of velocity attenuation is also bigger.The pestle body of this back not only can not improve energy to the forward effectively, and the hole that stays after also the forward can being penetrated is sometimes blocked, and forms plug-hole.In addition, arrive to a certain degree when the metal jet energy attenuation, jet can not successfully penetrate target body, and can only be more open to the target body structure, and the more weak direction of intensity is goed deep into, and the result forms inclined to one side hole.
The purpose of this utility model provides a kind of novel beehive-shaped charge, and it can make the energy of cumulative metal flow constantly be replenished, thereby improves penetration depth significantly, and can also reduce percentage of plugged hole.
Above-mentioned purpose is to realize like this.On the metal flow direction of existing beehive-shaped charge, add the reinforcement beehive-shaped charge that upper level, secondary or more multistage top and bottom are all opened wide.
Other structures of the present utility model are to adopt the delay charge of center break-through between adjacent two-stage beehive-shaped charge.
Delay charge employing explosion velocity is that the explosive of 2500～4000 metre per second (m/s)s is made.
A up big and down small curve form is preferably made in the penetrating part, center of delay charge.
The utility model also can add metal cap in the penetrating part, center of delay charge.
The beehive-shaped charge of making is like this compared with existing beehive-shaped charge, has following advantage.After uppermost initial beehive-shaped charge is detonated, produce first money paid for shares and belong to jet and pass through smoothly from the penetrating part, center of delay charge.Delay charge is subjected to detonating from the effect after the upper level beehive-shaped charge blast.After delay powder is detonated, produce metal jet upwards in the penetrating part, center, and it is bigger to stop the volume of following first burst of downward metal jet back, and slow pestle body is when delaying to finish, and the one-level that delay charge again will be following is strengthened the beehive-shaped charge ignition.So produce second strand of downward metal jet again, tightly follow after first strand, and provide energy effectively to it.This one-level is strengthened beehive-shaped charge and is ignited the delay charge that is positioned at below it again.The delay charge blast here produces metal jet upwards too and stops the pestle body of following second burst of downward metal jet back, and the reinforcement beehive-shaped charge of igniting next stage again when delaying to finish.The blast like this so repeatedly the one-level one-level propagate downwards, the energy of downward metal jet just constantly is compensated, thereby has improved penetration depth significantly.Because when partially the hole phenomenon only occurs in broken the first process and is about to termination, therefore, the raising of penetration depth just means the diminishing of ratio of inclined to one side hole depth and whole penetration depth.The energy of metal jet that penetrates target body in addition is big, just penetrate smoothly, so the wall quality of through hole also is improved.Also because the reverse metal jet that is all produced by the blast of the delay charge between the beehive-shaped charges at different levels back respectively at the pestle body behind the metal jet of following that each grade beehive-shaped charge blast back produces stops, so significantly reduced percentage of plugged hole.
Following drawings and Examples have provided more detailed description to the utility model.
Fig. 1 is the profile that one-level is strengthened the two-stage beehive-shaped charge specific embodiment of beehive-shaped charge that has that proposes according to the utility model.
This two-stage beehive-shaped charge is by initial beehive-shaped charge 1; The delay charge 3 of strengthening beehive-shaped charge 2 and being positioned between the two-stage beehive-shaped charge (1 and 2) constitutes.The fovea superior spherical shape is made in the penetrating part, center of delay charge 3.There is a metal cap 5 that can fit tightly with the surface on the surface of last concave spherical surface 4, and they generally are manufactured into an integral body.Metal cap 5 preferably is made of copper.The minimum place of the through hole of last concave spherical line diameter is 0.5～2 centimetre.It is the explosive manufacturing of 2500～400 metre per second (m/s)s that delay charge 3 preferably adopts explosion velocity, and its thickness calculates according to the explosion velocity and the powder charge overall dimensions of the high explosive of the explosion velocity of selected extension explosive, beehive-shaped charges at different levels, generally between 0.5～2 centimetre.
When reality is used, with initial beehive-shaped charge, strengthen beehive-shaped charge and delay charge and fuse by boning or putting shell, detonate from the top of initial beehive-shaped charge.The progression of strengthening beehive-shaped charge determines respectively according to the difference of service condition, one-level at least, but progression also can not be too many.When all height of strengthening beehive-shaped charges added that the height of all delay charges reaches the maximum distance that the metal jet of initial beehive-shaped charge can reach in air, the capacity usage ratio of initial beehive-shaped charge equalled zero.In this case, the progression of reinforcement beehive-shaped charge can be used as the limit of progression.
