Problems solved by technology

[0003] The purpose of the present invention is to solve the safety problems of semi-explosion, high misfiring rate, and large mass of explosion residual fragments existing in the current artificial rain-increasing hail bomb, and propose a steel-plastic combined human rain bomb fuze with an improved structure, which can be used in human After the rain bomb detonates normally, the residual fragments of the human rain bomb have a small mass and will not cause damage when falling

Embodiment Construction

[0012] Such as figure 2 with image 3 As shown, the steel-plastic combined rain bomb fuze is composed of a fuze body, a side firing mechanism, a time-delayed self-destruct mechanism and a detonator tube.

[0013] The fuze body 1 is divided into a lower steel body part 1-1 and an upper injection-molded plastic part 1-2. The steel body part is machine-added molding of No. 30 steel, and the upper plastic part is molded by injection molding. The plastic material is modified reinforced nylon SL-007 , the injection molding condition is that the plastic part is dried for 16h~24h and then preheated to 85°C±5°C, and then the steel part of the fuze body is preheated to 85°C±5°C, and the injection molding is carried out under the pressure of 90MPa~110MPa in the injection molding machine.

[0014] The time-delay self-destruct mechanism is composed of an upper positioning pin 13, an upper paper gasket 4, a medicine tray 3, a lower paper gasket 5, an adjusting paper pad 7, a lower positio...

Abstract

The invention relates to a steel-plastic combined fuse of an artificial precipitation projectile, which comprises a fuse body, a side ignition mechanism, a time delay self-destruction mechanism and an auxiliary detonator. The side ignition mechanism and the time delay self-destruction mechanism are installed on the upper part of the inner bore of the fuse body, the auxiliary detonator is installed at the lower part of the inner bore of the fuse body; the fuse body is combined by the fuse steel body at the lower part and the cast plastics at the upper part; the side ignition mechanism comprises an ignition base, the position beyond the center of the ignition base is provided with a groove; the time delay self-destruction mechanism comprises a middle priming tube, in which 611 pieces of miniature smoke gunpowder are equipped, the pressing quality of which is 53-58mg. The invention solves the problems of large quantity of residual fractions after the full explosion of artificial precipitation projectiles, the incomplete explosion, misfire, and the like existing in the artificial precipitation projectiles.

Description

technical field [0001] The invention belongs to the technical field of rain bomb fuzes, in particular to a steel-plastic combined rain bomb fuze. Background technique [0002] At present, the fuze (hereinafter referred to as the original fuze) used in artificial rain enhancement and hail suppression bombs is composed of a side ignition mechanism, a delayed self-destruction mechanism, a detonator tube, and a fuze body. Explosions, blind fires, and residual fragments from explosions are too large in quality, posing safety hazards. It has been verified by experiments that the currently used human rain fuze is mainly due to the mismatch of the transmission energy, and the output energy is too small to detonate or completely detonate the projectile, resulting in misfire or half-explosion of the human rain bomb. The large mass of the remaining fragments of the explosion is mainly due to the fact that the fuze body adopts an all-steel fuze body and the weight of the ignition seat ...
