Definitions
- the present invention relates to a multi-part cartridge case for centerfire ammunition. Furthermore, the present invention relates to centerfire ammunition, in particular with a caliber in the range from 4.6 to 12.7.
- Multi-part cartridge cases are known in principle and are subdivided at least into a base piece facing a firing pin and a case jacket firmly connected to the base piece.
- the known methods for joining the base piece and sleeve jacket have proven to be in need of improvement, particularly with regard to mass production and automation.
- DE 2720821 Ai discloses a cartridge case with a case jacket for the projectile and a rear base piece facing a firing pin for igniting the ammunition. A separate primer cap is not required for the cartridge case.
- the sleeve casing surrounds the base piece and is bent around the base of the base piece for positively locking the base piece and sleeve casing together.
- the base piece has a central receiving chamber for an ignition charge.
- an additional felt stopper has to be pressed into the bottom piece to delimit and seal the receiving chamber for the ignition charge.
- the felt wad is shaped to form an anvil as a support for the firing pin, the anvil extending into the receiving chamber.
- the cartridge case according to DE 2720821 Ai therefore has disadvantages in terms of the high number of parts and the complex assembly, in particular for inserting the felt plug and for ensuring the sealing of the ignition charge receiving chamber.
- the present invention is generally concerned with the improvement and simplification of centerfire ammunition which does not require a structurally separate, standard primer for igniting the centerfire ammunition.
- An object of the present invention is to overcome the disadvantages of the prior art, in particular to simplify and/or improve a cartridge case for centerfire ammunition, in particular in that the number of parts is reduced compared to the prior art and/or the assembly of the Cartridge case is facilitated, especially with a simplification of the sealing of the ignition charge receiving chamber.
- centerfire ammunition has a caliber ranging from 4.6 to 12.7.
- centerfire ammunition also known as a centerfire cartridge, is a centerfire cartridge.
- the central fire ignition is characterized by the fact that the ignition takes place centrally in relation to the central axis or axis of rotation. Ignition is initiated by a centrally guided firing pin.
- the cartridge case according to the invention comprises a rotationally shaped case jacket for receiving a projectile and propellant charge powder and a separate rotationally shaped base piece fastened to the case jacket.
- Generic multi-part cartridge cases are to be understood in such a way that the case jacket and the base piece are separate components or are manufactured separately.
- the sleeve jacket and base piece can be fastened in such a way that gas tightness is ensured.
- the base piece can have a central depression in which the sleeve jacket is partially accommodated. When the sleeve casing and base piece are fastened to one another, an outside of the sleeve casing is in contact with an inside of the base piece, in particular the indentation.
- the base piece can define an axis of rotation.
- An annular wall of the base piece on the sleeve jacket side can at least partially with respect to this Axis of rotation be conical.
- a base piece-side holding section of the sleeve casing can be adapted in shape with respect to the conical annular wall, so that the holding section reaches behind the annular wall at least in sections for fastening the sleeve casing and base piece to one another and removal of the base piece and sleeve casing in the direction of the axis of rotation and/or in the direction of torsion is prevented.
- the conical ring wall and the holding section can be formed by plastic deformation of the base piece and, in particular, of the sleeve jacket.
- the plastic deformation can take place by applying force from radially outside, in particular by pressing. In this way, a particularly simple and inexpensive cartridge case can be produced. In particular, a positive and/or non-positive fit between the base piece and the sleeve jacket can be achieved in this way.
- the plastic deformation of the base piece can cause an interlocking between the base piece and the sleeve casing, in particular such that the sleeve casing is held in place in the base piece and/or an axial and/or rotational relative movement between the sleeve casing and the base piece is avoided.
- a further advantage of this preferred realization of the attachment between the case casing and the base piece is that when the centerfire ammunition is fired using a firearm, the attachment between the case casing and the base piece is strengthened.
- a more extensive plastic deformation can accompany it, as a result of which the hooking or engagement structure is strengthened.
- a force-locking and/or form-locking attachment of the base piece and sleeve jacket can be made possible by performing deformation work.
- Neither the sleeve jacket nor the base piece requires additionally introduced and/or prefabricated fastening and/or hooking structures.
- the fact that the inner wall of the depression tapers towards the sleeve casing can be taken to mean that a free or open opening cross section of the depression is reduced. In other words, the inner wall can be inclined with respect to the central axis of rotation.
- the plastic deformation of the bottom piece can be demonstrated, for example, in the flow structure.
- the base piece has a closed ignition surface.
- the ignition surface is arranged to the rear with respect to the direction of flight of the projectile and/or to face a firing pin for igniting the centerfire ammunition.
- the The ignition surface delimits a receiving chamber for an ignition charge on the firing pin side or on the rear side.
- the pyrotechnic ignition charge can be accommodated in the receiving chamber and thus rests on the ignition surface.
- the sleeve casing has or supports an anvil that extends into the receiving chamber in the direction of the ignition surface.
- the bottom piece, which is closed at the rear, has a particularly advantageous effect on the gas-tightness of the cartridge case. Furthermore, due to the closed base piece shape, its stability is improved, in particular its resistance to the rear impact of the mechanical firing pin is increased. Furthermore, it is possible to flexibly define and select the distance between the ignition surface and the anvil.
- the support of the anvil on the case jacket, in particular on a base of the case jacket on the rear or firing pin side, can be understood in such a way that before the ammunition is fired there can also be a slight distance in the direction of the central axis or axis of rotation, which occurs as a result of the impact of the firing pin can be bridged to the ignition surface. If there is an axial distance between the anvil and the base of the sleeve jacket, the anvil can be fastened within the receiving chamber by means of a press fit relative to the base piece, in particular an annular wall delimiting the receiving chamber on the peripheral side.
- the anvil can be rotationally symmetrical.
- the anvil is arranged concentrically with respect to a central or rotational axis of the cartridge case, in particular of the case jacket and/or base piece.
- the anvil is aligned directly with the firing pin striking the center of the base piece or its ignition surface.
- the receptacle can be cylindrical in shape and arranged concentrically with respect to the center or axis of rotation of the base piece.
- the ignition surface has a smaller wall thickness than an annular jacket of the base piece connected to the ignition surface.
- the firing surface can be weakened compared to the remaining components of the base piece, so that the firing surface can be deformed to initiate firing of the cartridge case by means of the firing pin.
- the ignition surface can be formed in such a way that the base piece, in particular the annular wall adjoining the ignition surface, remains essentially intact.
- the ignition surface is at least 30%, 40%, 50% or 60% less in wall thickness.
- the sleeve shell and the anvil are made in one piece and/or by cold forming.
- it can be produced by deep-drawing or extrusion, in particular reverse extrusion.
- the sleeve jacket can have a substantially constant wall thickness.
- the case shell can be designed completely open at an opposite end of the anvil to accommodate the projectile.
- the bottom of the sleeve jacket can be cold-formed, for example, in such a way that it has the shape of the anvil.
- the case jacket has a closed base in which the anvil is formed and which has at least one ignition hole.
- the ignition holes serve to ignite the propellant charge powder to be arranged in the case shell as a result of the ignition of the ignition charge.
- the anvil forms the bottom of the sleeve jacket at least in certain areas.
- the case shell can therefore have a closed case structure oriented downwards or in the direction of the firing pin and open case structure oriented upwards or in the direction of the shot, in particular in the shape of a cup or cup, the bottom of which is then cold-formed to form the anvil.
- the at least one ignition hole can then be introduced.
- three ignition holes are arranged in the base at a uniform distance in the circumferential direction with respect to the axis of rotation or the central axis and/or surround the anvil concentrically.
- the ignition holes can lie on a common circumferential circle which is concentric is arranged with respect to the rotation or central axis and / or surrounds the anvil concentrically.
- the case jacket and the base piece are matched in shape to one another and/or are fastened to one another in such a way that the receiving chamber is sealed in a gas-tight manner in particular.
- no further components are necessary for sealing or closing the receiving chamber and the components of the multi-part cartridge case that are present anyway, namely the case jacket and the base piece, can be used.
- the sleeve jacket and the base piece can have mutually associated and coordinated support shoulders, which rest on one another in the assembled state and define an assembly end position, as well as jacket sections adjoining the support shoulders, which are oriented essentially in the longitudinal direction of the respective component and, for example, to form a press fit between Sleeve jacket and bottom piece are used.
- the case jacket and the base piece are pressed together.
- an inner measurement of the base piece for receiving the sleeve jacket can be undersized with respect to an outer dimension of the sleeve jacket.
- a press fit between the sleeve jacket and the base piece can be achieved, which is easy to manufacture and assemble.
- Acceptance of the press fit can be facilitated, for example, by the action of temperature.
- the sleeve jacket can be exposed to a low temperature before assembly and/or the base piece can be exposed to a high temperature prior to assembly, so that the sleeve jacket contracts and/or the base piece expands.
- a secure connection is achieved by the press fit through the sleeve jacket and base piece.
- the base piece has at least one support shoulder for the sleeve jacket for determining an axial assembly position viewed in the longitudinal direction, in particular an assembly end position.
- the support shoulder can be oriented transversely to the longitudinal direction be.
- the support shoulder is oriented essentially at a 90° angle to the longitudinal direction.
- the support shoulder can be designed in the form of a rotation.
- the at least one further bearing shoulder can be oriented transversely with respect to the longitudinal direction, whereby it can form an angle in the range of 15° to 60° with respect to the longitudinal direction.
- the case jacket supports the anvil in the longitudinal direction of the cartridge case.
- the anvil and the case jacket are separate components, in particular manufactured separately. It is possible for the anvil to lie particularly flat on the bottom of the sleeve jacket.

- the anvil is held in place in the base piece by a press fit.
- the anvil is oversized relative to the receiving chamber.
- the assembly of the anvil in the receiving chamber can take place, for example, under the influence of temperature.
- the anvil can be dimensioned and/or arranged in the receptacle in such a way that the receptacle chamber is closed, in particular in a gas-tight manner, by means of the anvil.
- the case jacket has a central ignition hole, in particular with a diameter in the range from 0.5 mm to 2 mm.
- a central ignition hole has proven to be advantageous when igniting the propellant charge powder and/or when propagating an ignition spark for igniting the propellant charge powder.
- centerfire ammunition is provided, in particular with a caliber in the range from 4.6 to 12.7.
- Centerfire ammunition also known as a centerfire cartridge, is a Centerfire cartridge.

- a cartridge case for centerfire ammunition is generally designated by the reference numeral 1.
- a cartridge case 1 according to the invention comprises the following main components: a rotationally shaped case jacket 3; and a rotationally shaped bottom piece 5 with a central recess 7.
- the cartridge case 1 can in principle be shaped in a rotational manner with respect to a rotational or central axis M.
- a first exemplary embodiment of a cartridge case 1 according to the invention is shown in sectional and plan views in FIGS. 1 and 2, which is illustrated in FIG.
- the sleeve jacket 3 is usually made of metal and has a substantially constant wall thickness along its length.
- the case jacket comprises a hollow, upwardly open cylinder section 9 and an adjoining neck section 11, the cross section of which is tapered in relation to the cylinder section 9.
- the case jacket 3, in particular the cylinder section 9, is open on a side 13 facing away from the base piece 5 to accommodate a projectile 10 (Figure 9).
- the neck section 11 comprises a bearing shoulder 15 which is inclined with respect to the central axis M of rotation in the direction of the base piece 5 and which extends in the radial direction up to a transition 17 which can form the radially innermost point. Starting from the transition 17, the cross section of the neck section 11 can widen again, so that an undercut 19 is formed, or it can remain essentially constant.
- the base-side jacket section 21 finally opens into a base 23, which can be designed to be essentially closed and is designed with ignition hole bores or ignition holes.
- the sleeve jacket 3, ie its cylinder section 9 and neck section 11, is made in one piece.
- the sleeve shell 3 can be produced by deep drawing or extrusion.
- the bottom piece 5 has a sleeve section 25 facing away from the sleeve jacket 3 and a jacket cut 27 adjoining it.
- the shell section 27 can be coupled to the sleeve section 25 via a pivot coupling 29 which can be, for example, a film hinge. It is possible for the jacket section 27, the sleeve section 25 and the hinge coupling 29 to be produced in one piece, for example by forming, cold forming, deep drawing, extrusion or reverse extrusion.
- the recess 7 goes into a receiving chamber 30 for an ignition charge 31 (Figure 9), which is in particular cylindrical in shape, in the region of the sleeve section 25.
- the sleeve section 25 comprises a base flange 33 facing away from the sleeve jacket 3, to which a substantially cylindrical section 35 reduced wall thickness connects.
- the cylindrical Section 35 ends on the inside in a radially extending support web 37 on which the bottom 23 of the sleeve jacket 3 rests.
- an outer wall 39 of the base piece 5 widens in sections and then extends essentially constantly, i.e. in the direction of the rotation or central axis M.
- the base piece 5 is closed at the rear or on the firing pin side. It has an ignition surface 47 on the rear side facing the firing pin 71 (FIG. 9), viewed in the firing direction.
- the ignition surface 47 delimits the receiving chamber 30 for the ignition charge 31 at the rear. In other words, the ignition charge 31 rests on the ignition surface 47 so that the ignition charge 31 can be ignited when the ignition is initiated by means of the firing pin 71 striking the ignition surface 47 at the rear.
- the manner of ignition is discussed in detail below.
- the ignition surface 47 connects the base flange 33 or the cylindrical section 35. Because the base piece 5 is closed at the rear, optimum gas tightness is ensured. In comparison to the adjoining components of the base piece 5 , the ignition surface 47 has a significantly smaller wall thickness, in particular around 50% less, so that the ignition can be reliably initiated by deforming the ignition surface 47 using the firing pin 71 .
- the jacket cut 27 can be shaped to form an undercut 41 or essentially shaped like a hollow cylinder and oriented essentially in the direction of the rotation or central axis M. It can also be seen in FIG. 1 that an inner contour 43 of the jacket section 27 is designed to be essentially complementary in shape to the outer contour 45 of the neck section 11 of the sleeve jacket 3 .
- the attachment of the sleeve casing 3 to the base piece 5 can be realized in that the casing section 27 of the base piece 5 is plastically deformed, as a result of which the undercut 41 is formed.
- the deformation of the jacket section 27, i.e. its radial inward bending, in particular around the pivot coupling 29, causes a deformation of the neck section 11 of the sleeve jacket 3, namely to form the undercut 19.
- This is particularly easy to implement in terms of production technology and is inexpensive way to be realized a reliable positive and / or frictional connection between sleeve jacket 3 and base piece 5 created.
- the anvil 49 is formed in a rotational shape and is arranged substantially concentrically with respect to the central axis M.
- the anvil 49 is formed in the bottom 23 of the sleeve jacket 3 .
- the base 23 accordingly comprises an outer ring bearing section 51 viewed radially with respect to the central axis M, which rests on the radial projection 37 which forms a bearing shoulder for the sleeve jacket 3 .
- the ring support section 51 merges continuously into the bell- or dome-like anvil 49 , which protrudes from the base 23 or the ring support section 51 in the direction of the ignition surface 47 and extends far into the receiving chamber 30 .
- a distance between ignition surface 47 and anvil 49, viewed in the direction of central axis M, can be a few millimeters and/or can be adjusted or produced individually.
- the anvil 49 has a convex shape, which finally merges into the ring support section 51 by means of a concave curved section 53, which is oriented essentially transversely, in particular perpendicularly, to the central axis M.
- FIG. 2 shows the cartridge case 1 according to FIG. 1 in plan view. Furthermore, the section line I-I can be seen schematically, on the basis of which the sectional figure according to FIG. 1 is formed.
- three ignition holes 22 are provided in the bottom 23 of the case jacket 3, arranged concentrically with respect to the center axis M and distributed uniformly in the circumferential direction with respect to the center axis M, via which the activation of the propellant charge powder 65 ( Figure 9) takes place.
- FIG. 3 shows a further exemplary embodiment of a cartridge case 1 according to the invention.
- the shape, in particular the curvature, of the anvil 49 is essentially identical.
- the difference also resides in how the anvil 49 is secured within the receiving chamber 30 .
- the anvil 49 can be supported in the longitudinal direction in the cartridge case 1 on a rear side of the base 23 of the case jacket 3 . For example, this can lie flat on it.
- the anvil 49 can be fastened by means of a press fit in the base piece, in particular in the sleeve section 25, which essentially delimits the receiving chamber 30 laterally.
- the case jacket 3 has a central ignition hole 22 provided in the base 23, which is larger in size than the ignition holes 22 according to Figure 2.
- a diameter of the ignition hole 22 can, for example, range from 0.5mm to 2mm.
- the base piece 5 can be shaped and manufactured identically.
- the cartridge case 1 is also ignited in an analogous manner.
- FIGS. 4 to 8 show a schematic production sequence of a base piece 5 of a cartridge case 1 according to the invention.
- a metal plate 55 is produced from a metal blank (not shown), for example stamped out.
- the metal plate 55 has, for example, a disk shape (FIG. 4).
- the basic shape of the final base piece 5 (FIG. 8) is then produced (FIG. 5) by a cold forming process, in particular deep drawing or extrusion, such as reverse extrusion.
- the circuit board 55 is cold-formed to form a cup 57 or a cup in such a way that the sleeve section 25 is essentially already completely formed or formed, which is closed at the rear by the ignition surface 47 .
- the hollow sleeve section 25 is subsequently reshaped further to form the depression 7 and the receiving chamber 30 (compare FIGS. 7 and 8).
- the rear shoulder to form the floor flange 33 is produced by pressing (FIG. 6).
- the sleeve portion 25 is inside to form a Pressed cone section 61, which widens like a tulip or flower and has a cone-shaped inner contour 63.
- the result is a cup 59 in the shape of a tulip or flower (FIG. 7).
- the inner contour of the base piece 5 is finally pressed, so that the depression 7 for receiving the sleeve jacket 3 and the receiving chamber 30 for receiving the ignition charge 31 are finally formed (FIG. 8).
- FIG. 9 shows an exemplary embodiment of a centerfire ammunition 2 according to the invention, with the cartridge case 1 being designed, for example, in accordance with the embodiment of FIGS.
- a projectile 10 is partially arranged in the sleeve jacket 3 and held in place by it.
- the sleeve shell 3 is also essentially completely filled with propellant charge powder 65, which is responsible for accelerating the projectile 10.
- the receiving chamber 30 which is delimited from the propellant charge powder 65 by the bottom 23 of the case jacket 3 , is essentially completely filled with an ignition charge 31 .
- An ignition device 67 for the cartridge case 1 is directly connected to the rear, ie underneath in FIG. This has a firing pin 71 which is guided centrally in a corresponding through hole 69 and which is mounted and held in a housing 73 . Firing pin 71 is sized and positioned to strike firing surface 47 substantially centrally to deform it. As a result of the deformation of ignition surface 47 in the direction of anvil 49, which acts as a counter bearing, ignition charge 31 in the receiving chamber is squeezed and displaced, and as a result of the resulting friction between the ignition charge powder grains with one another or with anvil 49 and/or ignition surface 47 , the activation of the ignition charge 31 takes place. The resulting gas expansion is transmitted via the ignition holes 22 into the interior 75 of the case jacket 3, in which the propellant charge powder 65 is located, in order to activate it and ultimately generate the gas expansion required to accelerate and launch the projectile 10.
- a further exemplary embodiment of a central fire service ammunition according to the invention can be formed by means of a cartridge case 1 according to the exemplary embodiment according to FIG.
