Glue-injecting bonding method for fragments and small-scale projectile

Abstract

The invention discloses a glue-injecting bonding method for fragments and a small-scale projectile. The method comprises the following steps: firstly, a base seat is placed on a plane table, and the front end of a projectile shell and a core mold are fixedly connected to the base seat by bolts; a certain number of the fragments are put into a gap formed between the projectile shell and the core mold, the fragments are uniformly and densely placed, and the upper surfaces of the fragments are flat; and finally a rear screw thread of the projectile shell is fixedly connected with a guard ring screw thread, prepared glue is slowly poured through the center of the core mold, the glue enters a center pouring channel through the center of the core mold, the glue of the center pouring channel enters a side pouring channel through a branch hole, the glue in the side pouring channel finally flows into the gap formed between the projectile shell and the core mold, the fragments are glued, then the glued fragments are allowed to stand, and after the glue is solidified, the upper surface of the gap is flattened. The method provided by the invention not only solves the problem that fragments move to form a bridge after glue is injected into a small-scale projectile, so that distribution of the fragments is not uniform, and ensures that the glue does not adhere to screw threads of a projectile shell.

Description

technical field [0001] The invention belongs to the technical field of adhesive fixation, and in particular relates to a glue injection bonding method for small-sized projectile fragments. Background technique [0002] Fragment killing projectiles are formed by the explosion of high-energy explosives to form a large number of high-speed fragments, and use the high-speed impact, ignition and detonation of the fragments to damage the target. Prefabricated fragments are made of fragments with pre-designed shape and quality. The inner surface of the projectile. Evenly distributed fragments are conducive to forming a denser killing effect within the set range, and the killing power of the whole projectile is greatly improved. For small projectiles, the turbulent flow effect of the glue filling during the glue filling process of the fragments is enough to make the The fragments move accordingly to form a bridge of fragments, which makes the distribution of fragments in the projec...

Problems solved by technology

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a glue injection bonding method for small projectile fragments, which not only solves the problem of uneven distribution of fragments due to the movement of small projectile fragments after glue injection, but also ensures that the glue Will not bond to the rear end threads of the body of the projectile
