Abstract
The utility model discloses and a kind of split type mould shell bullet, including bullet seat and shell case, the percussion coyote hole for holding primer mixture it is provided with and for holding the transmitting coyote hole of propellant powder in described shell case, described percussion coyote hole communicates with launching coyote hole, and the primer mixture of primer mixture indoor contacts with the propellant powder of propellant powder indoor, one end of described shell case is fixing with bullet seat to be connected, and the other end is provided with percussion bullport.This utility model mainly solves following two technical problem, and one is when moulding shell bullet and being duds, reduces the scrappage of nailing；Two is the percussion that can be applicable to different nail like members.
Description
Technical field
This utility model relates to nailing fastening field, particularly relates to a kind of split type mould shell bullet.
Background technology
Screw shooter can use various different power to fire, and such as compressed air, hydraulic pressure, electromagnetism, gunpowder etc., and uses
More is as power with gunpowder.In the screw shooter using gunpowder to be used as power, primer mixture has the most all been used to have shell case
Box hat bullet.Using box hat bullet currently on the market, by the standard production of GB19914-2005, one is indirect action power:
In use, by the gunpowder explosion in body, produce thrust, promote piston rod to hit nailing, promote nailing to enter matrix, reach
To the purpose of fastening, this mode, by then passing through piston rod transmission energy, therefore its shooting active force is less, causes nailing
High-mark cement can not be entered, do not reach the purpose of fastening.Another kind is to use direct active force: in use, pass through body
Interior gunpowder explosion, produces thrust, pushes directly on nailing, and nailing enters matrix after accelerating certain distance in gun barrel, reaches tight
Solid purpose, this mode, shooting active force is relatively big, can fasten high-mark cement, but the speed of ejection occurs very
Slow problem, reduces efficiency of construction.
In order to solve above-mentioned technical problem, prior art proposes be connected with nailing mould shell bullet, as China is special
Profit number " 01246083.4 " discloses a kind of Integrated shoot nail on April 10th, 2002, and its technical scheme is described disjunctor nailing
Playing non-shell pneuamtic nail bullet, bullet seat and nailing composition, nailing is fastened on one end of bullet seat, described nailing and bullet seat and becomes straight connection, tool
Have common centrage, the other end of bullet seat to be provided with the groove that can put into non-shell pneuamtic nail bullet, described nail shooting pill is embedding be attached to described
In the groove of bullet seat.This Integrated shoot nail in use, disposably put in gun barrel with moulding shell bullet by nailing, constructs more convenient,
But in actual use, nailing and nail shooting pill are that the structure of integral type there is also following defect:
One, nail shooting pill is in use, all there is duds phenomenon, and when nail shooting pill is duds, nailing will be caused to scrap,
The i.e. scrappage of nailing is higher.
Two, such nail shooting pill is only used for firing nailing, when firing other nail like members, needs additionally manufacture corresponding
Nail shooting pill, its scope of application is narrower.
Utility model content
The purpose of this utility model is to solve the above-mentioned problems in the prior art, it is provided that one is split type moulds shell
Bullet, this utility model mainly solves following two technical problem, and one is when moulding shell bullet and being duds, reduces the scrappage of nailing；
Two is the percussion that can be applicable to different nail like members.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of split type moulds shell bullet, it is characterised in that: include bullet seat and shell case, be provided with in described shell case and hit for holding
The percussion coyote hole of dispensing and for holding the transmitting coyote hole of propellant powder, described percussion coyote hole communicates with transmitting coyote hole, and primer mixture
Indoor primer mixture contacts with the propellant powder of propellant powder indoor, and one end of described shell case is fixing with bullet seat to be connected, and the other end sets
It is equipped with percussion bullport.
Described percussion coyote hole and transmitting coyote hole are cylindrical structural, and the volume launching coyote hole is 400 500mm3, percussion
The volume of coyote hole is 80 110mm3。
Described bullet seat and shell case are cylindrical structural, and the length of described bullet seat and shell case is 24.5mm, described bullet seat
It is 8.32mm with the external diameter of shell case.
Employing the utility model has the advantage of:
One, the shell bullet of moulding of Integrated shoot nail in prior art is peeled away by this utility model, not only solves and is moulding shell
When bullet is duds, the problem that nailing scrappage is high, also solve the problem that in prior art, the Integrated shoot nail scope of application is single,
I.e. use of the present utility model split type mould shell bullet after, it is possible to according to practical situation, for the percussions of difference nail like members, use face
Wider, effect is more preferable, has unexpected technique effect.
Two, in this utility model, percussion coyote hole and transmitting coyote hole are disposed as cylindrical structural, and the volume launching coyote hole sets
It is set to 400 500mm3, the volume of percussion coyote hole is set to 80 110mm3, the length of bullet seat and shell case is disposed as 24.5mm,
The external diameter of bullet seat and shell case is disposed as 8.32mm, and use such ad hoc structure and particular size moulds shell bullet, can either ensure
Shooting force during shooting nailing, has the most effectively saved resource.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Being labeled as in figure: 1, bullet seat, 2, shell case, 3, launch coyote hole, 4, percussion coyote hole, 5, percussion bullport.
Detailed description of the invention
One is split type moulds shell bullet, including bullet seat 1 and shell case 2, is provided with for holding hitting of primer mixture in described shell case 2
Dispensing room 4 and for holding the transmitting coyote hole 3 of propellant powder, described percussion coyote hole 4 communicates with launching coyote hole 3, and fires in coyote hole 4
Primer mixture contact with the propellant powder launched in coyote hole 3, one end of described shell case 2 is fixing with bullet seat 1 to be connected, other end setting
There is percussion bullport 5.
In this utility model, described bullet seat 1 and shell case 2 are cylindrical structural, described percussion coyote hole 4 and transmitting coyote hole 3
Being cylindrical structural, the volume launching coyote hole 3 is 400 500mm3, the volume of percussion coyote hole 4 is 80 110mm3, described bullet
The length of seat 1 and shell case 2 is 24.5mm, and the external diameter of described bullet seat 1 and shell case 2 is 8.32mm.
In this utility model, shell case 2 and bullet seat 1 all use highstrenghtpiston, the outside dimension of bullet seat 1 and the endoporus of gun barrel
Size closely cooperates (zero clearance cooperation).
Design principle of the present utility model is: the percussion coyote hole 4 between shell case 2 and bullet seat 1 is deposited respectively with launching coyote hole 3
Primer mixture and gunpowder, the primer mixture in percussion coyote hole 4 and the propellant powder close contact launching coyote hole 3, bullet seat 1 is closely joined with gun barrel
Close, reach the effect sealed.Its operation principle is: by the gunpowder explosion in shell case 2, produces powerful thrust, promotes simultaneously
Bullet seat 1 and rivet nut, rivet nut enters matrix and reaches the purpose of fastening, and bullet seat 1 and shell case 2 are taken out of by air-flow in gun barrel, reach to move back
The purpose of shell.
