Description
Technical Field
The invention relates to a method for shortening the cooling time of a gun barrel or a gun barrel.
Background
In the battlefield, because the bullet is ejected in the barrel, in the process of ejecting, high-speed bullet and barrel can have the friction to produce, and the friction can generate heat promptly, and a large amount of friction can lead to the barrel to send out the scald, reddish and expand with heat and contract with cold and take place the deformation. The simplest method is cooling. The typical design is a Makeqin machine gun, which uses water cooling. The specific heat of water is very big, through the contact of water with the barrel, directly reduces the temperature of barrel. In addition, an air cooling method is adopted, and the gun barrel is cooled on the outer surface of the gun barrel during manufacturing, so that the contact area of the gun barrel and air is increased, and the heat dissipation effect is achieved. The friction between the cannonball and the cannon barrel is also a problem which cannot be ignored in the process of launching the cannon barrel. According to the research: the range of the gun barrel of the artillery is greatly related to the initial speed, in addition, the longer the gun barrel is, the farther the range is, and in addition, the larger the volume of the explosive chamber is, the larger the range is; the greater the range anyway, the more favorable direction of the development of the artillery is certainly. But all this causes a high friction between the projectile and the barrel, in view of favourable range. As the cannonball is shot in the cannon barrel, the rifling is worn and ablated, the initial speed is reduced, and the service life of the cannon barrel is expired when the initial speed is reduced to a certain degree.

Detailed Description
All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.
Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
In the description of the present invention, it is to be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "central", "end", "length", "outer end", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.
Further, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
The use of terms such as "upper," "above," "lower," "below," and the like in describing relative spatial positions herein is for the purpose of facilitating description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
In the present invention, unless otherwise explicitly specified or limited, the terms "disposed," "sleeved," "connected," "penetrating," "plugged," and the like are to be construed broadly, e.g., as a fixed connection, a detachable connection, or an integral part; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 1, a reciprocating piston 3 is designed to move back and forth with perfect fit to the tolerance and barrel or barrel 4. The piston 3 is made of metal or metal alloy, the piston 3 is connected with a moving arm which moves back and forth, and the moving arm 2 is connected with an engine 1 or other machinery which generates piston motion.
The piston 3 is arranged in the barrel or barrel 4, the direction of the piston arrangement is not limited to vertical or parallel, and the tolerance of the designed piston barrel or barrel is 10mm-0.05 mm.
The method comprises the following specific steps:
1. 100ml of the mixed solution described in the invention is poured into 10 liters of SL engine oil and is stirred evenly for 30 to 60 minutes.
2. The gun barrel or the gun barrel is soaked with engine oil containing mixed liquid in advance, the piston is placed in the barrel, and the piston is connected with the engine through the moving arm.
2. The engine is started. The operation is carried out for 0.5 to 3 hours. When the engine oil is insufficient in the middle, the engine oil of the prepared mixed liquid should be supplemented.
3. After 3 hours of the friction welding process, a compact nanoscale boron nitride or other inorganic coating 5 which can greatly reduce friction force and resist high temperature should exist.
The coating can greatly reduce the friction force of the bullet or the cannonball. The reduced friction can effectively shorten the cooling time of the gun barrel or the gun barrel, further prolong the service life of the gun barrel or the gun barrel and improve the precision.
Wherein the mixed solution is prepared by taking serpentine powder, talcum powder, boron nitride, silica gel, kerosene, ethanol and base oil as the basis, and the mixed solution can adopt products sold in the market, such as: mechanical wear repairing liquid of Dalian dry technologies development Co., Ltd, wherein the mixed liquid is added to SL engine oil in an amount of not more than 1%.
The design principle is as follows: the friction is utilized to generate instant high temperature which can reach the temperature of more than 1000 ℃ of the order of zero to a few seconds, and the temperature can instantly melt the nanoscale boron nitride or other inorganic filling salts to fill the nanoscale boron nitride or other inorganic filling salts into tiny gaps on the tube wall; because the friction is continuously performed, the nano salt is continuously melted, and the gap is filled with the nano salt and then starts to be covered, and finally the nano film is formed. This process is scientifically called friction welding. The nano film will not be infinitely long and thick. The thickening stops when a certain thickness is reached.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
