Embodiment, belong to the scope of protection of the invention.
Embodiment one
The embodiment provides a kind of preparation method for launching box body, with reference to shown in figure 1, this method includes:
S101, using drawing process by the drawing of metal alloy blank formed metal alloy inner bag.
Here, the specific material of metal alloy blank does not limit, and it can be the gold such as magnesium alloy, titanium alloy, aluminium alloy
Belong to alloy;In view of reducing cost, preferably aluminium alloy.
Here, also it is not specifically limited for the number of drawing, can be depending on actual conditions.In view of improving drawing
Precision and quality, it is preferred to use multiple drawing.Example, once thick cold-drawn can be first used, is then pulled out again using a cold sperm.
It should be noted that before the drawing of metal alloy blank is formed into metal alloy inner bag using drawing process, also
Pickling processes can be carried out to metal alloy blank, to wash the oxide skin of metal alloy blank surface off, reduce friction, reduction is pulled out
Power processed, so as to prevent in drawing produce road plan the defects of.In addition, metal alloy blank drawing is formed using drawing process
After metal alloy inner bag, metal alloy inner bag can also be heat-treated, to reduce the degree of deformation, improve product essence
Degree.Heat treatment can be solution treatment, Ageing Treatment and annealing etc..
Here, also do not limited for the shape of metal alloy inner bag, can be according to the transmitting box body for being actually subjected to production
Shape depending on.Example, the shape of the metal alloy inner bag can be cylinder(Shown in Fig. 5)Or long square tube, certainly, metal
The shape of alloy inner bag can also be other shapes, no longer illustrate one by one here.
S102, metal alloy inner bag outside formed thermal insulation layer.
Here, also do not limited for the specific forming method of thermal insulation layer.In addition, do not done for the specific material of thermal insulation layer
Limit, at least need to meet heat-insulated requirement.
It should be noted that in subsequent technique, fibrous layer can be formed in the outside of thermal insulation layer.Launch using firing box
During guided missile, amount of heat can be produced.And the performance of fibrous layer is affected by temperature bigger, exceed certain value in temperature(Such as:
100℃)When, the performance of fibrous layer and life-span can have a greatly reduced quality.Therefore, set between metal alloy inner bag and fibrous layer heat-insulated
Layer can ensure the temperature of fibrous layer within its temperature in use.Meanwhile during storing with transport missile, be advantageous to protect
The temperature in firing box is held in prescribed limit.
S103, using winding process thermal insulation layer outside formed fibrous layer.
Here, winding process can be wet-winding craft either dry method winding process, with specific reference to actual conditions
It is fixed.The particular type of fibrous layer does not limit, it is contemplated that performance and technological problemses, preferably PE fibrous layers, PE fibrous layers refer to surpass
High molecular weight polyethylene fiber layer.
S104, fibrous layer is post-processed, to form transmitting box body.
Here, post processing can be including curing process etc., to ensure to launch the performance of box body.

Include:The drawing of metal alloy blank is formed by metal alloy inner bag using drawing process;Metal alloy inner bag outside formed every
Thermosphere;Fibrous layer is formed in the outside of thermal insulation layer using winding process;Fibrous layer is post-processed, to form firing box case
Body.This method forms metal alloy inner bag using drawing process, while forms fibrous layer using winding process, compared to existing skill
Art, the production time is saved, reduce complex procedures and production cost;Meanwhile the transmitting box body formed by this method
With light weight, ballistic performance is good, intensity is big the characteristics of.
Optionally, S103, using winding process thermal insulation layer outside formed fibrous layer include:
Fiber yarn sheet to be wound is entered according to the first winding angle and the second winding angle on the outside of metal alloy inner bag respectively
Row first is wound and the second winding.It can obtain winding fibrous layer uniform, of good performance by above-mentioned winding method.
Optionally, the scope of above-mentioned first winding angle is 85 ° -90 °, such as:It can be 86 °, 88 ° etc.;Above-mentioned first
The number of plies of winding is 1 layer -5 layers, such as:It can be 2 layers, 4 layers etc..The scope of above-mentioned second winding angle is 40 ° -50 °, example
Such as:It can be 42 °, 44 °, 48 ° etc.;The number of plies of second winding is 80 layers -90 layers, such as:It can be 84 layers, 86 layers, 88 layers etc..
It should be noted that in order to improve the intensity of winding and quality, can be to silvalin to be wound before being wound
Piece carries out dipping process, while controls fiber gel content within the specific limits.If gel content is too high, the transmitting box body of formation
Intensity can reduce;If gel content is too low, the increase of the transmitting box body space of formation, it can cause to launch the air-tightness of box body, resistance to
Ageing properties and shear strength decline.Therefore, it is necessary to strictly control the gel content of fiber, ensure that whole winding process is front and rear and contain glue
Amount is uniform.Optionally, gel content should be controlled in 17%-25%, and preferably gel content is 20%.
Further, since fiber is all to use fiber size for reinforcemeent, storage is improper also to adsorb substantial amounts of moisture.Fiber surface
These free moistures influence the bonding of resin matrix and fiber, while cause stress corrosion, the defects of making micro-crack is further
Extension, so that product strength and ageing-resistant performance decline.Therefore, after dipping process is carried out to silvalin piece to be wound, and
Before coiling, drying and processing can also be carried out to silvalin piece to be wound.Fiber drying parameter can be according to fiber moisture content
Depending on spindle size, in general, 24h can be dried at 60 DEG C -80 DEG C.
Optionally, in order to reduce drawing difficulty while improve operability, with reference to shown in figure 2, S101, using drawing process
