Breech and weapon system with the breechblock

Abstract

In order to ensure that forces acting on a breech drive when unlocking the breech and pulling out a cartridge case are reduced or even eliminated, a breech of a weapon system is proposed which is formed at least by one breech carrier and one breech head and the breech carrier supports the breech head. The breech carrier and the breech head can be mechanically separated from one another. This separability is achieved in that a control case which has at least one control cam is inserted in the breech carrier. In addition, the breech head has a control bolt which engages in the control cam of the control case and can be guided in it. This measure ensures that the forces acting upon the recoil of the weapon cannot act on the breech drive.

DETAILED DESCRIPTION

(10) In FIG. 1 and FIG. 2, a breech 100 of a weapon system, not represented in detail, is shown. The breech 100 consists of at least of one breech carrier 1 and one breech head 2. The breech head 2 is carried by the breech carrier 1. A control bolt is marked with 3. This is attached to the breech head 2.

(11) A firing pin 4 can be integrated in the breech head 2. A case 5 is inserted in the breech head 2. This case 5 guides the firing pin 4. At least one dowel pin 26 fixes the case 5 in the breech head 2. At least two dowel pins 26 can preferably be installed.

(12) A slider is marked with 6, a ring with 7 and a pin with 27. The firing pin 4 can be cocked via the slide 6, the ring 7 and the pin 27 as well as a compression spring 21 when the breech 100 is cocked (FIG. 2, FIG. 5). The slide 6, ring 7, pin 27 and compression spring 21 are integrated in the breech head 2 at the end as seen in the firing direction.

(13) A control case which can be inserted into the breech carrier 1 is marked with 8. The control case 8 has at least one control cam 34 in which the control bolt 3 of the breech head 2 can be guided. This control case 8 holds the breech head 2 via the control bolt 3.

(14) Two control cams 34 are preferred. These control cams 34 are in turn provided on both sides in the control case 8. The control bolt 3 can engage in the two control cams 34. This measure enables a symmetrical arrangement or design. In addition, this construction allows the control bolt 3 of the breech head 2 to be held loosely on the firing pin 4 in a bore 38 leading through to the breech head 2.

(15) FIG. 3 shows the breech carrier 1 in a representation from below. A release lever 12 can be fastened to the breech carrier 1 below it by means of a washer 13 and a screw 14. The release lever 12 can be mounted displaceably by the washer 13 and the screw 14. This has the advantage that, for example, small manufacturing tolerances of the components involved can be compensated for. The release lever 12 interacts functionally with a first slide 9.

(16) FIG. 4 shows a sectional representation B-B from FIG. 3. A latching pin 15, a dowel pin 28 and a spring 31 are represented here. This spring 31 is preferably designed as a compression spring.

(17) The latching pin 15, the dowel pin 28 and the spring 31 are housed in the ring 7. The dowel pin 28 limits the path of the latching pin 15. The compression spring 31 holds the latching pin 15 in the rest position. A blocking slide 10 (FIG. 1) corresponds to the latching pin 15.

(18) FIG. 6 is a sectional representation C-C from FIG. 5. The control case 8 is provided with a detent 35. This is preferably integrated at the side. The first slide 9 can act on or in this detent 35 (FIG. 8). For this purpose, the slide 9 is preferably designed as a latching slide.

(19) FIGS. 7 and 8 show the breech 100 without the breech carrier 1 in a lateral perspective representation. A limit stop is marked with 33. This is preferably designed as a spring limit stop with a spring 36 and is supported on the breech carrier 1.

(20) An exemplary operation is as follows:

(21) The breech 100 is brought in the actual weapon function from a firing position to a presentation position and vice versa in a known manner via its breech carrier 1 by a breech drive (not shown in detail), for example an external drive such as a chain drive.

(22) During the downtimes of the breech 100, the drive continues to run within a groove 11 made below the breech carrier 1. The breech 100 is mechanically separated from the drive during its downtimes and is located in the weapon system.

(23) At the time a shot is fired, the breech 100 is locked to a weapon barrel (not shown in more detail), i.e. is mechanically connected to it. As a rule, the weapon barrel has a chamber case. The breech head 2 of the breech 100 is then locked to the chamber case of the weapon barrel.

(24) When the shot has taken place, the breech head 2, the chamber case and the weapon barrel and possibly a recoil suppressor run opposite the breech carrier 1 against the firing direction. The breech carrier 1 and the breech head 2 can be mechanically separated from one another at this point in time. The breech carrier 1 itself is not a component of the returning masses.

(25) When the breech head 2 is returning, i.e. during the recoil and the returning of the returning masses, the slide 9 is ineffective. During return, the slide 9 is controlled.

(26) After reversing the weapon return, i.e. when the returning masses advance, the slide 9 blocks the control case 8 via the detent 35. The breech head 2 with the chamber case or weapon barrel rush further forward. The breech head 2 rotates via the control bolt 3 within the control cam(s) 34. When the locking between the breech 100 or the breech head 2 and the chamber case or the weapon barrel is cancelled, the breech 100 is unlocked from the weapon barrel. The breech head 2 is held in place by the control cam 34 of the control case 8 via the control bolt 3 and is caught in the latter. This creates a mechanical connection between the breech head 2 and the breech carrier 1.

(27) The chamber case and the weapon barrel are brought forward as the returning masses advance until they have reached their starting position. With the advance, a cartridge case is at least partially pulled out of the chamber case or the weapon barrel, which hangs on an extractor 17 on the breech head 2.

(28) The breech carrier 1 and breech head 2 are moved together via a breech drive in the weapon function into a rear position in which a new cartridge is presented to the breech 100.

(29) In order to support the transfer of the breech 100 within the scope of the actual weapon function, the breech carrier 1 provides at least one guide bore 37. This interacts with a guide, not shown in detail, of the weapon or the weapon system.

(30) The release lever 12 runs in the end position on a weapon-side cam during the return or transport of the breech 100 within the scope of the actual weapon function. The release lever 12 actuates the slide 9 and thereby releases the control case 8. In the loading position, the slide 9 is controlled.

(31) The ring 7 and the breech head 2 are then pushed back against the spring 36 of the limit stop 33, i.e. against a resistance, into the front end position thereof in the loading and feeding function of the actual weapon function. This can be done by a buffer, not shown in detail, on the weapon housing.

(32) When the breech 100 advances in the actual weapon function, the slide 10 now blocks the control case 8 and corresponds to the latching pin 15. The possibility of rotating the breech head 2 is blocked by means of the latching pin 15. The blocking slide 10 can be pressed into its rest position by a spring 30 and a blocking plate 16. The blocking plate 16 can be fastened to the breech carrier 1 by means of button-head screws 25, for example.

(33) The cycle begins again with the onset of the weapon return.

(34) The weapon system can fire both targeted single shots and continuous fire.

(35) 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.
