Abstract
Description
Technical Field
[0001] The utility model relates to accessories for a weapon launching box, in particular to a fragile cover of the weapon launching box. Background Art
[0002] The fragile cover of the weapon launch box serves as a sealing cover for the weapon launch box and has the following characteristics: 1) When the missile is stored and transported, the fragile cover must be able to withstand a certain pressure and have good sealing performance; 2) When the missile is launched, the separation piece in the middle must be directionally broken along the separation groove under a certain pressure and can be quickly opened and broken, so as not to affect the flight trajectory of the missile.
[0003] At present, the fragile cover of the weapon launching box is composed of an outer frame and a separation piece in the middle. The outer frame and the separation piece in the middle are both composed of multiple layers of glass cloth stacked together. The usual practice is: after the glass cloth used to form the outer frame and the separation piece are stacked layer by layer, the mold is closed and heated to melt the glue originally impregnated with the glass cloth, and then the product of the fragile cover of the weapon launching box is formed after solidification.
[0004] However, we found that the products prepared by this method have the following defects: 1) The stacking of glass cloth is usually done manually, which makes it difficult to perfectly align the upper and lower layers of glass cloth, resulting in uneven thickness at the edge of the separator; 2) The glass cloth needs to be pressurized during heating, which will cause the glass cloth to shift in the glue under the action of pressure.
[0005] All of the above have seriously affected the performance requirements of the fragile cover of the weapon launch box, which can easily cause the edges of the separation pieces to overlap together. In severe cases, it may even cause the separation pieces to be unable to break, thereby affecting the normal launch of the missile. Utility Model Content
[0006] The utility model provides a fragile cover for a weapon launch box, the fragile cover for the weapon launch box comprises an outer frame, the outer frame is provided with a central hole, and a plurality of mounting holes for connecting with the weapon launch box are arranged around the outer periphery of the central hole;
[0007] A plurality of prefabricated fan-shaped separators are arranged in the central hole, and gaps are arranged between adjacent fan-shaped separators and between the outer edge of each fan-shaped separator and the inner circle of the outer frame. Each fan-shaped separator is pre-cured and cut from multiple layers of dry glass fiber cloth.
[0008] The outer frame and the fan-shaped separation piece are connected together by coating glue, wherein the glue covers the outer surfaces of the outer frame and the fan-shaped separation piece and fills the gap.
[0009] Furthermore, the outer frame is composed of several layers of stacked glass fiber cloth.
[0010] Furthermore, each of the fan-shaped separation pieces and the outer frame is provided with 20-40 layers of glass fiber cloth.
[0011] Furthermore, each of the fan-shaped separation sheets is provided with 30 layers of glass fiber cloth.
[0012] Furthermore, the central hole is a circular hole, and four prefabricated sector-shaped separation sheets are arranged in an enclosed manner in the central hole.
[0013] The utility model ensures the uniformity and consistency of the edge of the separator, avoiding product defects caused by uneven stacking of glass cloth. At the same time, the separator is directly placed in the glass fiber cloth of the outer frame, reducing manual operation, reducing processing difficulty, and improving production efficiency. In addition, since the separator has been pre-cured, it is not easy to deviate during the heating and pressurizing process, further ensuring the performance requirements of the product.

[0019] In order to thoroughly understand the present invention, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.
[0020] Reference Figure 1As shown, the utility model provides a fragile cover for a weapon launch box, which comprises an outer frame 1, which is composed of a plurality of stacked layers of fiberglass cloth. The outer frame 1 is provided with a central hole 2, and a plurality of mounting holes 3 for connecting with the weapon launch box are arranged around the outer periphery of the central hole 2. The outer frame 1 is fixed to the port of the launch box by screws.
[0021] like Figure 2 As shown, multiple prefabricated fan-shaped separators 4 are arranged in the central hole 2, and gaps 5 are arranged between adjacent fan-shaped separators 4 and between the outer edge of each fan-shaped separator 4 and the inner circle of the outer frame 1. Each fan-shaped separator 4 is made of multiple layers of pre-cured and cut glass fiber cloth. The outer frame 1 and the fan-shaped separator 4 are connected together by coating glue 6. The glue 6 covers the outer surface of the outer frame 1 and the fan-shaped separator 4 and fills the gap 5 (i.e., the separation groove). Figure 3 shown.
[0022] In an optional embodiment, each sector-shaped separator 4 and the outer frame 1 are provided with 20-40 layers of glass fiber cloth. Preferably, each sector-shaped separator 4 is provided with 30 layers of glass fiber cloth. While ensuring the sealing performance, the separator 4 can be broken under a predetermined pressure.
[0023] In an optional embodiment, the central hole 2 is a circular hole, and four prefabricated sector-shaped separation sheets 4 are arranged in the central hole 2 and are surrounded and distributed.
[0024] The preparation method of the utility model is as follows:
[0025] 1) Pre-solidify 30 layers of fiberglass discs together and then cut them into 4 required fan-shaped blocks.
[0026] 2) stacking the fiberglass cloth used to form the outer frame layer by layer;
[0027] 3) Place each fan-shaped block directly in the center hole of the glass fiber cloth on the outer frame;
[0028] 4) The mold is closed and heated to melt the glue originally impregnated with the glass cloth, and then solidified to form a fragile cover of the weapon launch box.
[0029] The advantages of the utility model are: 1) each separation sheet is formed by pre-curing and cutting, which improves production efficiency; 2) since the separation sheet is formed by pre-curing and cutting multiple pieces of glass cloth, displacement of the glass cloth can be avoided during the subsequent heating process, making the boundary of the finally formed fragile cover separation groove clearer, which is conducive to the breakage of the separation sheet.
