Embodiment Construction

[0050] The present invention will be further described below in combination with specific embodiments.

[0051] see together Figure 1-15 , a method for manufacturing a fragile rear cover of a weapon system launching tube, the steps comprising:

[0052] The first step, flange ring production:

[0053] Machining a circular flange ring 1 with a height of 2-8cm and a diameter of 14-19cm; the outer side of one end of the flange ring 1 is processed and installed with an external thread 1a; the flange ring 1 A number of sockets 1b for inserting wrench rods are processed on the outside of the shell, which is convenient for fastening the flange on the launch tube. The flange ring 1 is also provided with a rubber sealing ring installation groove.

[0054] The second step, making the cage:

[0055] On the circumference of the other end of the flange ring 1, several tie-down pieces 3a are welded evenly at intervals. The tie-down piece 3a is a metal plate in the shape of a shovel. Pre...

Abstract

The invention relates to manufacturing methods of back covers, particularly to a manufacturing method of a breakable launcher back cover of a weapon system. The method comprises firstly, fabricating a flange ring and processing mounting external threads at one end of the flange ring; secondly, fabricating a holder in an approximate skullcap shape; thirdly, making prepreg glass fiber cloth into type A composite material sealing pieces and type B composite material sealing pieces, putting a plurality of the type B composite material sealing pieces inside the holder, then putting a plurality of the type B composite material sealing pieces outside the holder and further putting a plurality of the type A composite material sealing pieces outside the holder; placing the holder with the stacked composite material sealing pieces inside a mould, performing compression molding, heating and pressurizing to achieve solidification forming; lastly, performing demoulding and forming slots in the inner side of the composite material sealing layer. The launcher back cover is breakable, and the roots of broken pieces are tied to the flange ring and avoid drop-off, so that normal launching can be guaranteed, and meanwhile floor cleanliness and tidiness of a launch site can be maintained.

Description

technical field [0001] The invention relates to a method for manufacturing the rear cover of a launch tube, in particular to a method for manufacturing a fragile rear cover of a weapon system launch tube. Background technique [0002] The launch tube is a device used to store and launch missiles. The tube body and the front and rear covers together form a closed container, which protects the missiles in the tube from external factors such as high temperature, low temperature, moisture, corrosive medium, electric field, and magnetic field. and a barrier to interference. At present, there are mainly two technical schemes for launching missiles in the form of a launch tube: the throwing cover and the fragile cover, and the fragile cover technology is currently used more. Crushed caps are blown into pieces within a controlled size range. Therefore, the front and rear frangible covers must not only be sealed and have a certain mechanical strength, but also must have fragile cha...
