Embodiment Construction
[0011] DRAWINGS The invention is described in further detail below in conjunction.
[0012] Combine figure 1 An artillery projectile projectile base rifled mechanical fuze, the fuze body lumen 9 in order from top to bottom comprises coaxially arranged detonators, safety and arming mechanism, the gasket 17, ballistic spring 13, ignition means, against 8 ball.
[0013] Wherein the squib comprises a downwardly opening housing a squib, transfer press fitted within a booster charge squib case 2, a booster shell 1 and closure 2 Booster reinforcing cap 3 pairs, with to strengthen the cap 3 with respect to the adjustment of the squib case a gap depth gasket 17. Booster selected black polyethylene -14 booster charge. That is, the end surface of the squib pass squib housing end surface 1, and the upper end surface 9 fuze toroidal body substantially flush. As an output terminal of the fuse, the top tube is a booster charge and the main projectile projectile is adjusted Emulsion paper mat. 9 ...

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...
