Vacuum filling and sealing device for warhead

Abstract

The invention discloses a vacuum filling and sealing device for a warhead. The vacuum filling and sealing device comprises a filling and sealing device body and vacuum extraction equipment arranged on the filling and sealing device body, wherein the filling and sealing device body comprises a cover plate used with a shell opening part of the warhead, and a hopper used for storing filling and sealing gum; a hopper bracket used for fixing the hopper and the cover plate is also arranged between the hopper and the cover plate; a blanking valve is arranged at one end of the hopper close to the cover plate; and a feeding hole of the hopper is directly connected with the atmosphere. According to the vacuum filling and sealing device, the powder charge shell opening of the warhead is sealed to vacuumize a powder charge cavity body so as to reduce the filling resistance of the filling and sealing gum; and meanwhile, the filling and sealing gum is filled in the vacuum powder charge cavity body and a small gap between powder and a shell by the atmospheric pressure so as to solve the difficult problem that the filling and sealing gum is difficultly filled into the small gap between the powder and the shell.

Description

technical field [0001] The embodiment of the invention relates to a device for potting a warhead of a weapon. Background technique [0002] The warhead is the ultimate damage unit for all kinds of ammunition and missiles to damage targets, and is mainly composed of shells, combat charges, detonators and safety devices. Modern warfare puts forward higher requirements on the killing power or damage efficiency of the warhead, and also requires higher safety performance. [0003] At present, the warhead charge of conventional weapons is usually filled with melt-cast explosives and castable heating-curable explosives. When charging by casting, the heated explosives and organic materials will be flowing liquids at a certain temperature, such as 65°C to 120°C. state, after being mixed and cast into a mold or shell, heated and solidified and cooled to form, this process will have volume shrinkage and looseness (shrinkage); at the same time, due to thermal expansion between the char...

Problems solved by technology

For the potting of small gaps, it is difficult to fill the potting glue in place, and it cannot fill 50% of the required amount within 5 to 6 hours. After a longer time, the process flow time of the potting glue has passed, and the potting glue cannot continue. potting

In order to avoid the safety problem of the gap between the drug and the shell and the difficulty of filling the gap, many warheads are charged with the pre-prepared combined powder column and potting glue at the same time, which will greatly reduce the warhead loading. The amount of charge affects the power of the warhead, and greatly increases the complexity of the charge preparation process and the charge cost, and this filling method cannot be realized for warheads with irregular geometric dimensions and mouths smaller than the main body size

In the method of vacuum injection filling and sealing, putting the entire warhead and charge into the vacuum to inject the potting glue requires a large vacuum device, and at the same time there is no pressure injection with external pressure, although it can greatly improve the potting performance. The efficiency of glue injection shortens the potting time, but this method requires a large vacuum device, so it is difficult to achieve
