Gun barrel is the important component part of barrel, is the main body of cannon fighting capacity.High temperature resistant, the high pressure of gun barrel, friction, corrosion are very large difficult problems always for a long time, and it directly has influence on the service life of gun barrel.During artillery shooting, powder gas can make the temperatures as high more than 1500 DEG C of thorax wall in gun barrel, may cause ablation and the distortion of gun barrel, and impact is normal to be used and repeatedly uses, and therefore causes larger economic loss.
For reducing costs and alleviating big gun weight, people adopt composite to manufacture gun barrel, but limit to by base material and special process, its inwall of composite bore after completing when shell high-speed cruising to high temperature bear and limited to the ability to bear of flame impingement, cause shell launch after inwall there is peeling off even delamination.
In view of above description, urgently there is a kind of structure unique, the generation of the composite tube type gun barrel that high temperature resistant and flame resistant is washed away.
Utility model content
The purpose of this utility model overcomes prior art defect, provides a kind of structure unique, the composite tube type gun barrel that high temperature resistant and flame resistant is washed away.Composite tube type gun barrel described in the utility model, for above-mentioned technical problem, gun barrel structure is improved, composite tube type gun barrel after improvement can not only ensure that the weight of self can not increase overweight, and inwall quality requirement fully can meet repeatedly use and the harmless ability of inwall under the washing away of high temperature and flame, select a kind of metal material as bore inwall, thus thoroughly solve the ability of high temperature, high pressure and flame impingement that nonmetallic composite can not carry, overcome composite self-defect.
For achieving the above object with some objects, the utility model discloses a kind of composite tube type gun barrel, it is characterized in that, comprising:
Internal layer cylinder, it is a hollow cylinder, and the lateral wall of described internal layer cylinder arranges multiple projection, and described multiple projection opens the multiple annulus of distribution formation along the cross section excircle uniform intervals of internal layer cylinder;
Middle level cylindrical shell, it is spliced mutually by the long side face of multiple strip lamellar body, upper surface along described strip lamellar body is through to lower surface and is provided with multiple first through hole, to make the madial wall of described middle level cylindrical shell be resisted against on the lateral wall of described internal layer cylinder, described multiple projection is extended by the first through hole;
Outer layer barrel, it is arranged on outside the cylindrical shell of described middle level, and the thickness of described outer layer barrel is 200-500nm.
Preferably, described composite tube type gun barrel also comprises:
Multiple groove, it to be arranged between every two described annulus and parallel with described annulus, and the A/F of described groove is 0.5-1.5mm, and the degree of depth is 100-500um;
Multiple retainer plate, itself and multiple groove one_to_one corresponding are arranged on the madial wall of middle level cylindrical shell, and A/F and the degree of depth of the width of described multiple retainer plate and height and described groove adapt.
Multiple second through hole, it is arranged on strip plate body along described retainer plate is through;
Bent fastening line, it, through in the second through hole of multiple strip plate body, is spliced into middle level cylindrical shell to make multiple strip plate body.
Preferably, described internal layer cylinder is stainless steel.
Preferably, the thickness of described internal layer cylinder is 0.2-0.5mm.
Preferably, interface glue bond is passed through between described internal layer cylinder and outer layer barrel.
Preferably, described interface glue is modified version epoxy resin.
Preferably, described outer layer barrel is electrodeposited coating.
Preferably, described electrodeposited coating is chromium coating.
The beneficial effects of the utility model are that composite tube type gun barrel is made up of three layers of cylindrical shell, and internal layer cylinder is stainless steel, and internal layer cylinder is born shell and run contact surface, can bear the environment of the HTHP produced when shell is launched; Middle level cylindrical shell is composite, reduces the weight of gun barrel; Outer layer barrel is chromium coating, adds the hardness of gun barrel.The utility model by arranging multiple projection on internal layer cylinder, middle level cylindrical shell is arranged multiple first through hole, the madial wall of middle level cylindrical shell is made to be resisted against on the lateral wall of internal layer cylinder, groove on internal layer cylinder is corresponding with the retainer plate on the cylinder inboard wall of middle level, increase friction, avoid the coming off of internal layer cylinder when shell is launched.The fastening line of bending on the cylindrical shell of middle level, what multiple strip plate body can be made to splice is more firm.The zinc coat of outer layer barrel not only adds the thickness of gun barrel but also is filled with the space of middle level cylindrical shell.In a word, the utility model, structure is unique, and high temperature resistant, high pressure resistant, flame resistant is washed away.
