Base mechanical trigger fuze of rifle gun grenade

Abstract

The invention discloses a base mechanical trigger fuze of a rifle gun grenade. A booster tube shell, booster explosive, a reinforcing cap, a gasket, a ball cover, an isolation ball, a needling detonator, a split ring, a ball seat, a firing pin, a ballistic spring, a firing pin sleeve, a self-destruction spring, an inertia body, a striking ball and a centrifugal ball are arranged in a fuze body, wherein the booster tube shell, the booster explosive, the reinforcing cap, the gasket, the ball cover, the isolation ball, the needling detonator, the split ring, the ball seat, the firing pin, the ballistic spring, the firing pin sleeve, the self-destruction spring, the inertia body and the striking ball are coaxially arranged from top to bottom, and the centrifugal ball is eccentrically arranged. The isolation ball serves as an explosion-proof piece and forms a ball rotor together with the needling detonator. At ordinary times, the ball rotor is locked at an explosion-proof position by the firing pin and the split ring, so that redundant insurance is realized. The firing pin and the split ring relieve the safety of the ball rotor by means of recoil and rotation environments during firing. The ball rotor also realizes a deferred safety release distance which is more than 20m. The fuze has the functions of floor blasting, large-angle ignition and centrifugal self-destruction, and when the fuze is applied to an antiaircraft gun grenade with the caliber of 35 mm, reliable triggering can be achieved when an aluminum alloy target plate with the thickness of 2 mm is vertically hit. Related requirements of the fuse safety design criterion GJB373B-2019 are met.

Description

Technical field [0001] The present invention belongs to the mechanical rotating projectile fuze technology, particularly to a rifled mechanical artillery projectile projectile base fuze. Background technique [0002] Small-caliber shells generally refers to a diameter of 20 mm to 40 mm, the use of artillery launch and complete destruction, explosion, fire or other ammunition tactical purposes, due to the flexibility of its strong, fast launch speed, is widely used in land, sea, air force and other combat forces. [0003] Small caliber gun with a grenade multi-warhead mechanical fuze. Compared with mechanical fuze warhead, small caliber artillery projectile equipped with a mechanical fuze projectile base, conducive to the realization of the fuze explosion, redundancy insurance, water-resistant, insensitive degree, trigger delay, wiping fried, with a large angle angry Require. Switzerland 35 mm anti-aircraft missile is equipped with a multi-functional grenade on the end of mechanic...

AI Technical Summary

Problems solved by technology

Excluding the tracer tube attached to the bottom, the entire fuze has about 37 components, and the structure is relatively complicated, so the cost is difficult to control and the reliability is also difficult to guarantee
