The specific embodiment
The present invention relates to a kind of modularization barrel assembly 10 (Fig. 1) that is used for gun F; it can use usually multiple different materials with a plurality of sections in other words the part form make; so that reduce to result from the linearity that forms this barrel assembly and the manufacturing cost and the waste product of concentricity problem, at the same time can also weight reduction significantly under the situation that does not influence this gun performance nocuously.In one was used for illustrational example embodiment, barrel assembly 10 of the present invention was shown as the part of a shotgun F with recipient 11 in Fig. 1, and this recipient comprises: a front portion that limits this chamber 12 of gun therein; A firing controller 13 that comprises trigger 14; A holder handle 16; A magazine tube 17 and a magazine lid 18.Yet should be appreciated that the principle of the invention also can be used for being formed for all other type gun, comprise rifle and other spear, also may be the modularization barrel assembly of pistol.
As described in Fig. 1-3, barrel assembly 10 of the present invention generally comprises a breech part 20 and gun barrel parts 21 in zone in other words, breech part 20 will link to each other with a mating part in the chamber 12 of this gun recipient 11 and communicate as shown in Figure 1, and gun barrel part 21 is connected on the downstream aperture of breech part 20 and recipient 11 and stretches out forward.Usually, this breech and gun barrel part will separately be made, and fit together then and form a modularization barrel assembly 10 of finishing as shown in Figure 3.
Breech part 20 is usually with for example metal or metal alloy manufacturing of steel, titanium or other high strength, rigidity and durability of a kind of high-strength material, and this is because this breech part will stand during this gun shooting usually by an ammunition the highest chamber pressure that for example propellant is lighted a fire and caused in bullet or the canister shot bullet.As illustrated in fig. 1 and 2, this breech partly will be about the 8-10 inch usually, perhaps be about one and finish 1/4 to 1/3 of barrel assembly 10 length, but this breech part can also form according to longer or shorter length as required.This breech part can also for example be used for making the metal stock of whole barrel assembly traditionally or manage to forge usually and form with one.Yet,, form the required forging operation of this breech part and just can therefore and obviously reduce if this breech portion size reduces.In addition, because breech part 20 is significantly shorter than traditional gun barrel, it also can form with an even cross-section facial canal or excellent machined, and does not need to remove a lot of materials from this pipe.
Fig. 1 to 3 further indicates, and breech part 20 generally includes a lengthening body 25, and this body 25 has one first end rear end 26, second end front end 27 and limit a hole path 28 that passes it in other words in other words.The rear end 26 of this breech part is formed collar sleeve 29 in other words usually, its have one as 31 places represent towards these breech part front end 27 diminishing increasings enlarged diameter in other words.The rear end 26 of this breech part 20 is suitable for recipient 11 engagements and the coupling with gun F, and as shown in Figure 1, align with the hole path 28 that extends through this breech part 20 and be communicated with in the chamber 12 of recipient simultaneously.The rear end of breech part 20 will be arranged mesh and install against this recipient usually with a kind of tight press fit, thereby fix against the front end face of this recipient, as shown in Figure 1.
As described in Fig. 1 and 2, gun barrel part 21 will be separated manufacturing with breech part 20 usually, and use the manufacture process different with this breech part usually.This gun barrel part will comprise the elongated workpieces of this barrel assembly usually, and can form by various different lengths according to the needs of different application occasion or gun.For example, short barrel length can be used to launch the canister shot bullet so that the impact decentralization of broad is provided, and the application scenario that long barrel length can be used for using bullet or slug.This gun barrel part can also be interchangeable in case can be as required or hope change this gun barrel and partly be applied to different application scenarios.
Fig. 2 further describes a plurality of different parts of gun barrel part 21, generally include first end 35 and the second end muzzle part 37 in other words, thereby tapered front end 27 couplings of a gun barrel connector 36 and first end 35 and breech part 20 are installed at described first end 35 places so that gun barrel part 21 is connected the complete barrel assembly 10 that forms on the breech part 20 as shown in Figure 3; And described the second end 37 can be admitted a muzzle insert 38 therein.Shown in Fig. 1 and 2, gun barrel connector 36 generally includes a tubular body 39 that limits the hole 41 of passing it, and has first end rearward end 42 and the second end leading section 43 in other words in other words.Gun barrel part 21 further comprises thorax pipe section 44 in other words, it can and can also form the inside rifling that has along its endoporus 46 by all in other words length formation of difference, endoporus 46 extends through thorax pipe 44, and endoporus 46 is aimed at the hole 28 of this breech part when partly assembling with breech.
Because the thorax pipe of the gun barrel part 21 pressure-tight degree of section 44 in other words requires to be usually less than breech part 20, thorax pipe 44 can be with all different materials manufacturings than breech part lightweight.For example, comprise steel, aluminium and/or than all metals of lightweight durability metal or metal alloy usually with forging or machined forms the pipe of desired length.Because exist the tapering of minimum degree also can use than lightweight metal material usually for this thorax Guan Eryan, thereby form forging or the machined that this thorax pipe usually need be less by a kind of like this metal material, waste product also still less.As an alternative, in order to reduce weight more significantly, thorax pipe 44 can also form with all synthetic or composites, for example comprise the carbon of carbon, glass, graphite, boron, nickel plating and/or the fibrous material of silicon-carbon fiber, and resin complexes, pottery, all highstrenghtpistons, nylon and/or other similar rigidity durable material.The various exemplary resin may comprise epoxy resin, polyamide, alkyd resin, thermoplastic resin and/or other similar resin material.The formation of this compound or synthetic thorax pipe can be finished with all manufacturing technologies that comprise filament winding, pultrusion and roll extrusion encapsulation process.
In a roll extrusion encapsulation process example, can be by the unidirectional or balance stratiform textile material of lamination arranged in form series of layers (being generally 3-4 or more multi-layered) or bar, for example carbon fiber tape or similar compound fabric material.Usually, can use a kind of unidirectional pre-preg (pre-preg) fabric, the all fibres of composite fiber fabric carried out pre-preg with a kind of uncured resin in fact therein, and most of fibers of this textile material filament (axis for the hole 46 that extends through this thorax pipe is 90 ° approximately) on hoop in other words are bonding, and that its cofibre (is roughly parallel to the axis in hole 41) in the vertical is directed so that extra longitudinal stability and hot strength is provided, and it is directed so that provide further torsional stability to this thorax pipe perhaps (for example to be about 45 ° with respect to this axially bored line) at a plurality of different angles place.Multiple dry fabric also can use with the resin material that applies during a subsequent processes with a subsequent step.Axle that will form this thorax pipe inside diameter and surface is placed on an end place of the heap of textile material or a plurality of lamination or a plurality of layers usually.Then this fabric assembly is rolled up around the tight ground roll of axle, this for example can be by means of using the workbench with fixed head and a portable plate, and described fixed head and portable plate piling up between two plates applies load compressive force in other words on the tissue layer.This portable plate will with the direction of this axle axis normal on slide, thereby this axle is twisted on this axle under the constant pressure this textile material lamination or layer being rolled, thereby form a compound bar or pipe, and this axle is in its center.
Seal this compound bar or pipe with a transparent band shape or strip material then, so that keep crushing stress around this rod outside.Then solidify whole assembly, method commonly used is: place it in the curing oven and stand the above temperature of 325 and reach about 2 hours, perhaps be coated in other temperature that the resin material on a plurality of layers may need and At All Other Times with curing.As an alternative, this resin material can be by chemosetting, for example by means of amine/epoxy resin, acid anhydride/epoxides and/or acid catalysis epoxide reaction.From extracting this axle out the cured bar, stay this composite bore tube then.Then, polish this thorax pipe outside usually, for example,, apply a transparent coating after this usually so that smooth, a smooth surface layer is provided by means of polishing or grinding this pipe outer wall.
As an alternative, a compound synthetic in other words a kind of filament winding process of thorax Guan Nengyong creates, and with a filament wrapping machine many or multilayer one-way fabric material is intertwined in this process.During this process, can stop off and on twining so that apply a plurality of one-way fabric extra plays, this layer manually is placed on this assembly usually so that realize the zero degree orientation of this layer in this compound preform.
Further substitute as a kind of, a compound synthetic in other words thorax Guan Nengyong pultrusion method forms, a kind of therein composite, for example a kind of pottery or fibrous material with the superincumbent resin of coating, be used for further solidifying the heating mould of this composite with being pulled through one, thereby form the pipe that a length suits the requirements.This process can provide minimum per unit length cost usually; Yet can not providing usually, it does not seal with roll extrusion or the winding method provides finished product thorax pipe identical strength level.
In addition, as shown in Figure 2, a ventilated rib 47 can be installed so that strengthen rigidity rigidity in other words along breech and gun barrel part.This ventilated rib member 47 can constitute by single-piece form (Fig. 3) or multistage form (Fig. 1 and 2), and can be with all materials for example aluminium or other metal or for example be similar to the carbon fiber formation of thorax pipe 44 so that weight reduction with all synthetic composite materials.This rib member 47 can be by means of using epoxy resin or similar binding material, fusion, welding, soldering (promptly being used for a metal ribs is connected on a metal thorax pipe and the breech part), securing member to come attaching to be connected in other words on breech and the gun barrel part, and perhaps it can form by the thorax pipe with this gun barrel part during making this thorax pipe.
In order to assemble barrel assembly of the present invention, this gun barrel part will be connected on this breech part, indicated as Fig. 2 and 3, the tapered front end 27 of breech part 20 is received in the open back end 42 of main body 39 of gun barrel connector 36 simultaneously usually, and their rib member part 47 is aimed at the close-fitting engagement system.Usually, the breech of barrel assembly 10 and gun barrel part are available for example carries out metallurgy with welding, fusion, soldering, soft soldering or multiple similar connection method and is connected; For example by use multiple securing member for example between pin, bar, screw, banding material, the part be threaded and/or other similar connector carries out mechanical connection; Perhaps by using epoxy resin, resin or other binding material to carry out chemical bonding or connection.The result is, thereby this breech and gun barrel part can interconnect securely and form barrel assembly 10 completely, as shown in Figure 3.
In addition, for the barrel assembly of for example in Fig. 1 and 2, roughly describing that is used for shotgun, gun barrel connector 36 can comprise a locking ring 48 that extends along its bottom, in this ring, can admit an end of magazine tube 17, as shown in Figure 1, and magazine lid 18 tightened by screw thread usually or be attached to this magazine beyond the Great Wall so that this barrel assembly is fixed on this gun recipient with other method.Therefore, thus lid 18 and magazine tube 17 are guaranteed in the engagement at locking ring 48 places that the breech of barrel assembly 10 and gun barrel part are fixed together by close-fitting meshing relation and are prevented that recoil or gas from leaking.A kind of like this connection further makes and is divided into possibility needn't changing the barrel portion that can change this gun barrel under the whole gun barrel situation of these gun quickly and easily.
The personnel that are familiar with this technology should be appreciated that, principle of the present invention can be adapted to comprise rifle, shotgun and other spear and as required or the required form that also may be all different gun of pistol with barrel assemblies.Therefore, modularization gun barrel system of the present invention make be used for the one-tenth that a kind of gun convert the shooting different model fast to send out ammunition for example the firearm barrels interchangeability of canister shot bullet, rifle slug or the like become possibility, and maintenance and the replacing that can provide convenience for a firearm barrels when needed.The present invention further can use during making barrel assembly than light material, and this makes again and be used for this barrel assembly thereby reduce for its tangible cost and the weight of gun, and be convenient to create possibility for this barrel assembly.
