Danger uses air damping principle, and the insurance of touching thorax is mainly realized by the radial constraint that shell case and barrel inner wall provide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram one of heavy caliber smooth bore explosive projectiles bullet contact fuze of the present invention.
Fig. 2 is the structural schematic diagram two of heavy caliber smooth bore explosive projectiles bullet contact fuze of the present invention.
Fig. 3 is that the present invention and shell case 9 and barrel inner wall are coupled schematic diagram.
Specific embodiment
Present invention is further described in detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of heavy caliber smooth bore explosive projectiles bullet contact fuze, including head trigger mechanism, sheet
Body 2, traveller 5, recoil drag and detonating primer 6 are provided with the lateral chamber an of accumbency on ontology 2 along its horizontal direction, from
2 end face center of ontology is provided with downwards the quadravalence through-hole that a diameter is sequentially reduced and communicates with lateral chamber, the quadravalence through-hole
It is followed successively by first through hole, the second through-hole, third through-hole and fourth hole from up to down, ontology 2 is provided with one from bottom center upwards
A the first second order through-hole communicated with lateral chamber, is followed successively by fifth hole and the 6th through-hole from bottom to top.2 bottom surface of ontology is under
A second second order through-hole is eccentrically provided on and, diameter is sequentially reduced and communicates with lateral chamber.Head trigger mechanism is located at this
In 2 quadravalence through-hole of body, traveller 5 is lying in 2 side of ontology into chamber, and recoil drag is located at the second second order through-hole of ontology 2
Interior, at the top of recoil drag in insertion traveller 5, detonating primer 6 is arranged in the first second order through-hole.
The head trigger mechanism includes firing pin 1 and cumulative output type stab detonator 3.Firing pin 1 is in flat, cumulative output
Formula stab detonator 3 is riveted in 2 third through-hole of ontology, and top surface passes through limit of closing up.1 top surface of firing pin is lower than the top surface of ontology 2, hits
Needle 1 is riveted in the second through-hole, so that 3 end face center of tip alignment cumulative output type stab detonator of firing pin 1,1 side wall of firing pin
It is thicker thus have enough axial strengths.The head trigger mechanism can be used for large caliber ball cartridge bullet contact fuze and light-caliber cannon
Bullet contact fuze is played, be can solve and fallen safety and trigger sensitivity, fry with wiping, the lance between big angle of entry Fire Reliability
Shield.Cumulative output type stab detonator 3 is then used to improve because igniting propagation of explosion at a distance using detonator brought by slide column type explosion-proof part
The ability of pipe.Fusehead shape design must take into account aerodynamic resistance properties, with shell case in conjunction with, fall safety, wiping act on it is anti-
The aspects such as ricochet.
Traveller 5 is second order ladder shaft-like, and the diameter positioned at outside is big, is radially provided with outside a circle on the big axle body of diameter
Annular groove, for cooperating recoil drag.
Recoil drag includes safety plug 4, safety plate 7 and bracket 8, and safety plug 4, safety plate 7 and bracket 8 are respectively positioned on
In two second order through-holes, safety plug 4 is protruded into the outer groove of traveller 5, and bracket 8 is located at the lower section of safety plug 4, safety plug 4 and bracket 8 it
Between be equipped with safety plate 7.
The lateral chamber is the second-order blind holes inwardly opened up from side wall, and built with traveller 5, the two is closely matched
It closes.Traveller 5 and ontology 2 match, and flame proof safety, delay arming and touching thorax safety may be implemented, protect wherein delaying to release
Danger uses air damping principle, and the insurance of touching thorax is mainly realized by the radial constraint that shell case 9 and barrel inner wall provide (such as Fig. 3 institute
Show).Traveller 5 is designed using stairstepping, can reliably be thrown away under rotation status from loading end.2 upside of traveller 5 and ontology
It is smaller to the annular gap between chamber, to form damping when shifting movement outside traveller.
The lateral chamber is three rank through-holes being sequentially reduced from the diameter that side wall inwardly opens up, 5 outside cylinder of traveller
The sealing compound rouge (see figure 2) of certain viscosity is coated on face and ontology 2 between lateral chamber wall, forms gas resistance by three rank through-holes
Buddhist nun's effect.More consistent using this structural principle damping action, arming range distribution can be reduced.Traveller 5
Diameter is slightly larger than 3 diameter of cumulative output type stab detonator, real such as copper alloy or stainless steel using the preferable material of explosion insulation performance
Existing explosion insulation performance.Cumulative output type stab detonator 3 can realize reliable propagation of explosion in the case where propagation of explosion distance is more than detonator diameter.
Usually, traveller 5 is locked in flame proof position by safety plug 4.When transmitting, 4 recoil of safety plug is cut in recoil drag
Safety plate 7 is cut, the recoil of traveller 5, which is insured, to be released.Before bullet goes out thorax, radial constraint of the traveller 5 by shell case 9 and the offer of barrel inner wall
Realize touching thorax insurance, bullet go out after thorax and revolving speed greatly to a certain extent when, 5 centrifugalization of traveller and air damping effect gradually
Radial to be detached from fuse, propagation of explosion channel is opened, and fuse is in arm-to-arm.Radial motion of the traveller 5 under the influence of air damping be
It is fuse delay arming process.After bullet is hit target, firing pin 1 is hit cumulative output type stab detonator 3 by tampering action stamp,
Cumulative output type stab detonator 3 is under fire and ignites booster explosive, then ignites bullet.
If traveller 5 surprisingly fails arming but not also in assembled state, after bullet is hit target or is landed,
Cumulative output type stab detonator 3 is under fire, and fuse is in state fiery absolutely, is conducive to the explosive disposal safety of bullet.
