Abstract
The utility model provides a high thermal conductivity light weight gun barrel which comprises an inner steel barrel. Carbon fiber strengthened epoxy resin is wound on the outer portion of the inner steel barrel, a layer of metal nickel is plated on the surface of the carbon fiber strengthened epoxy resin, and adjacent nickel plated layers are in tight contact in the winding process. According to the high thermal conductivity light weight gun barrel, a carbon fiber strengthened composite material with high specific strength and high specific modulus mechanical properties is adopted in an outer barrel, the light weight can be ensured, and meanwhile gun barrel shooting accuracy is effectively improved. The metal nickel plated layer enables heat inside the gun barrel to be quickly transmitted to the outer portion of the gun barrel, heat dissipation of the gun barrel is accelerated, bore ablation is slowed down, shooting frequency is ensured, and the service life of the gun barrel is prolonged.
Description
Technical field
The utility model relates to a kind of gun barrel, specifically a kind of high heat conduction lightweight gun barrel.
Background technology
Gun barrel is the main member of automatic weapon, and in automatic weapon all component, its major function comprises: filling bullet, dependence powder gas are given the certain initial velocity of bullet, guiding bullet heading etc.In full rifle, quality proportion is larger, and therefore, gun barrel lightweight can effectively alleviate full rifle weight.Adopting lightweight structure of gun barrel and adopting lightweight material is the effective way of gently changing gun barrel.
At present, existing gun barrel Lightweight Technology adopts nonmetallic composite laminated structural design or composite segmentation wound form structural design on metal barrel mostly.Because it is thin that gun barrel has tube wall, firing rate is high, and the feature such as thermal capacity is little.If gun barrel heat-sinking capability poor after burst-firing in gun barrel temperature can sharply rise, accelerate in thorax ablation, the barrel life will shorten.And the gun barrel of existing nonmetallic composite laminate structures design is because of composite poor thermal conductivity, can not fast dissipation of heat in gun barrel be gone out, for ensureing the barrel life, radio frequency will be restricted.Although composite segmentation wound form gun barrel has had certain improvement but has sacrificed the fire accuracy of gun barrel at heat dissipation problem.
Utility model content
The purpose of this utility model overcomes existing lightweight gun barrel poor thermal conductivity exactly, life-span is short, and the limited deficiency that waits of radio frequency, in the case of ensureing the lightweight effect and working strength of gun barrel, promote the heat conductivility of gun barrel, fire accuracy and the service life of when ensureing certain radio frequency, improving gun barrel.
The utility model for the technical scheme that realizes above-mentioned object and adopt is: a kind of high heat conduction lightweight gun barrel, it is characterized in that: at the outside carbon fiber reinforced epoxy resin that is wound around of steel inner tube of gun barrel, described carbon fiber reinforced epoxy resin surface plating layer of metal nickel; When the carbon fiber reinforced epoxy resin of described plating nickel on surface is wound around in the steel inner tube of gun barrel, ensure adjacent nickel coating close contact.
The beneficial effects of the utility model are: the carbon-fibre reinforced epoxy resin of plating nickel on surface is wrapped in gun barrel in steel inner tube and has the mechanical property of high strength, high elastic modulus, intensity can ensure to shoot time, and compare common gun barrel high specific strength, high ratio modulus material can produce less vibration amplitude, can effectively improve gun barrel fire accuracy.In the time of outer Filament Wound Composite, close contact between adjacent metal nickel coating under the effect of tensile force, the heat that can ensure gun barrel inside is radially delivered to gun barrel outside fast, accelerate gun barrel heat radiation and guarantee that internal layer temperature is unlikely too high, slow down inner tube ablation, when ensureing gun barrel radio frequency, improve the barrel life.

Detailed description of the invention
As depicted in figs. 1 and 2, a kind of high heat conduction lightweight gun barrel, comprise steel inner tube 1, at the carbon fiber reinforced epoxy resin 2 of the outside twisting surface nickel plating of steel inner tube 1 of gun barrel, this winding layer material has high specific strength, high ratio modulus, resistant to elevated temperatures superior mechanical property, can fully ensure working strength and the lightweight effect of gun barrel as the cladding material of gun barrel; Described this winding layer material as shown in Figure 3, adopt the method plating layer of metal nickel 4 of chemical plating on the surface of carbon fiber reinforced epoxy resin 3, and with its thickness of electric plating method control, metallic nickel 3 is metal materials of a kind of Wear-resistant, high-temperature resistant, fusing point 1450, thermal conductivity factor 90W/mk, compares stainless steel and has more excellent thermal conductivity, and adhesive force is reliable, can under various complicated, ensure not aliquation; In order to ensure intensity and the heat conductivility of gun barrel, when the carbon fiber reinforced epoxy resin 2 of plating nickel on surface is wound around in the steel inner tube 1 of gun barrel, winding angle α keeps 65 degree to make gun barrel reach the highest working strength as shown in Figure 1; In the time being wound around, material surface need keep tensioning simultaneously, to ensure adjacent plating nickel 4 interlayer close contacts, and then ensures the good thermal conductivity of gun barrel.
