Breechblock of a weapon system and weapon system with the breechblock

Abstract

A breechblock for a weapon system having a recoilable barrel and having a breechblock carrier and a rotatable breechblock head. The breechblock head is carried by the breechblock carrier. The breechblock carrier has a control cam that is divided into a number of, preferably at least four, cam sections. The actual weapon function and the unlocking of the breechblock or of the breechblock head are combined in this control cam. The breechblock head comprises a control pin, which engages in the control cam and can be guided therein. Attached to the breechblock carrier are two blocking slides, which keep the breechblock head in one of two different positions, in which positions the breechblock head can enter or leave the locking portion of the barrel, namely, a forward position in the course of the actual functioning of the weapon and a rear position during the advancement of the returning masses.

DETAILED DESCRIPTION

(6) A breechblock 100 is shown in FIG. 1. Breechblock 100 is formed from at least one breechblock carrier 1 and a breechblock head 2. Breechblock head 2 is carried by breechblock carrier 1. Breechblock head 2 has a control pin 3. Control pin 3 is attached at the periphery of breechblock head 2. Breechblock carrier 1 has a control cam 4 in which control pin 3 can be guided.

(7) Control cam 4 is divided into preferably four cam sections 4.1-4.4. A front first cam section 4.1, seen in the firing direction, represents the locking of breechblock head 2 with a barrel (not shown in more detail). This locking is completed when control pin 3 enters a second cam section 4.2. Both cam sections 4.1, 4.2 are associated with the actual weapon function. Part of the second cam section 4.2 and two subsequent cam sections 4.3, 4.4 serve the purpose of weapon recoil, in particular the return of the returning (moving) masses as well as the advance of the moving masses up to the advance of the moving masses without breechblock head 2.

(8) A firing pin 5 is inserted in breechblock head 2 and is preferably held in a sleeve (not shown in more detail). Firing pin 3 in breechblock head 2 can be tensioned by a slide 6 via a ring 7. For this purpose, a firing pin spring, for example, which is not shown in more detail, is placed around firing pin 3.

(9) Two so-called blocking or locking slides 8, 9 are attached to breechblock head 2. Breechblock head 2 can be held in its “open position” within the scope of the actual weapon function with blocking slide 8. Blocking slide 9 serves to ensure that, during the advance of the returning masses, breechblock head 2 can be locked or held in the rear “open position” (detent point 16, FIG. 2).

(10) Blocking slide 8 and blocking slide 9 retain their end positions with the aid of at least one bar 10 and at least one guide pin 11. This bar 10 and guide pin 11 limit the stroke of the two locking slides 8, 9. Bar 10 can be secured in breechblock carrier 1 by means of cylindrical screws, etc. Compression springs (not shown in more detail) hold blocking slides 8 and 9 in their upper end position. A tension pin 12 secures guide pin 11 in breechblock carrier 1, and a further tension pin 13 secures the sleeve (not shown in more detail) in breechblock head 2.

(11) The unlocking of breechblock 100 or of breechblock head 2 as well as the extraction of a cartridge case (not shown in more detail) will be considered in more detail with reference to FIG. 2:

(12) At the time of firing, control pin 3 is in the second cam section 4.2 of control cam 4. Breechblock 100 is locked. When the shot has been fired, the returning masses are moved against the firing direction. Control pin 3 runs along cam section 4.2. During this time, breechblock head 2 and the locked barrel run opposite to the firing direction. As the returning masses continue to move, i.e., as the moving masses return, control pin 3 is guided along cam section 4.3 of control cam 4. Breechblock head 2 thereby executes a rotary movement. By means of this rotary movement, breechblock head 2 is released from the barrel or a chamber sleeve of the barrel. Breechblock head 2, released from the barrel, and the barrel continue to run together to the rear, against the firing direction and within cam section 4.4 of control cam 4. Blocking slide 9 is ineffective in this case and overruns.

(13) At the end of the return, part of the recoil energy is stored in the recoil springs of a return mechanism or the like (not shown in more detail). The returning masses are moved forward again using this energy, when these are in the advancing position.

(14) As the moving masses advance, blocking slide 9 engages and holds breechblock head 2 in its “open” position. The released barrel, on the other hand, is moved further forward and moves ahead of breechblock head 2. A cartridge case hanging on an extractor claw 15 of breechblock head 2 is partially extracted from the barrel with the cartridge chamber.

(15) The empty cartridge case is then removed during the actual weapon function when breechblock 100 is transferred to its ejector and loading position via a weapon drive or breechblock drive (not shown in more detail). While breechblock carrier 1 is moved to the ejector and loading position, blocking position 16 of breechblock head 2 is released by slide 9 and breechblock head 2 is pushed to the front “open position” 17. In this position, blocking slide 8 on breechblock head 2 can lock breechblock head 2 with breechblock carrier 1, preferably axially.

(16) A new cartridge can be provided to breechblock 100 or breechblock head 2 in the loading position. Breechblock 100 and the cartridge are then transported in the firing direction by means of the breechblock drive. Breechblock 100 is locked to the barrel or a chamber sleeve in a known manner via control cam 4, cam sections 4.1 and 4.2, and the breechblock drive. Here, control pin 3 of breechblock head 2 runs along control cam section 4.1 into control cam section 4.2. Breechblock 100 and the barrel are locked again.

(17) The cycle starts again with the firing.

(18) For transporting breechblock 100 as part of the actual weapon function, breechblock carrier 1 can have lateral guides or guide holes 18, 19. These are matched to guides (not shown further) in the weapon system.

(19) Breechblock carrier 1 may have a groove 20 underneath, in which, for example, a connecting rod (not shown in more detail) of the breechblock drive can engage and be guided similar to WO 2017/009114 A1.

(20) The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
