Definitions
- the invention relates to the connection of pipe sections of combustible propellant charge cases according to the preamble of claim 1.
- DE 30 34 360 A1 discloses a combustible propellant charge sleeve made of at least two elastic tubular parts with coaxially pluggable connecting sections with radially deformable interlocking elements.
- the invention relates to the connection of pipe sections of combustible propellant charge sleeves from one or more coils of textile threads which are connected with binders, the binders containing propellants.
- these propellant charge sleeves are dimensionally stable and have a high mechanical strength.
- So z. B. the tearing force with the same wall thickness of the sleeve, in comparison to the sleeve according to DE 30 34 360 A1, higher by a factor of 40-56.
- Such a propellant charge sleeve is described in the generic DE 38 25 581 C1.
- the invention has for its object to provide a connection of pipe sections of combustible propellant charge cases according to the preamble of claim 1, with which a stable, tight and tight connection is achieved even with these dimensionally stable propellant charge cases and no uncontrolled crack formation can occur during the connecting process.
- This connection technology is required, e.g. B. to build ammunition, to attach the projectile or also to hold the combustible part with the metallic bottom piece, which receives the ignition and the sealing of the hot swaths when the propellant powder burns to the cartridge chamber.
- this object is achieved in that the pipe sections to be connected are nested, that the nested pipe sections are connected via a non-releasable snap connection, and that at least one longitudinal section extending in the area of the connection is arranged in the axial direction.
- Inserting the pipe sections to be connected in connection with the snap connection results in a secure, firm and tight connection.
- at least one longitudinal section extending in the area of the connection is arranged in the axial direction. This is an essential feature of the invention, which only gives the desired results in combination with the other features mentioned.
- the pipe sections are locked by barbs.
- the barbs can have a cross section such. B. rectangular contour or preferably also have a rounded cross section. This makes it easier to plug the two pipe sections into one another.
- adhesive is used in addition to the snap connection mentioned.
- annular depressions or grooves are expediently arranged on the connecting surface of the pipe sections to accommodate adhesives.
- the adhesive can then be distributed from these recesses and grooves when inserted into the available locations.
- curable multicomponent systems such as. B. based on polyurethane or epoxy resins used.
- radially circumferential sealing rings are arranged on the connecting surface and are embedded in the two pipe sections to be connected.
- the connection surfaces are otherwise flat.
- further embodiments can be used. These are, for example, threads, bayonet and conical shapes. In all cases, the simultaneous use of adhesives is preferred.
- connection is preferably used for ammunition components and ammunition cases.
- Fig. 3 two pipe sections which are connected to each other via a sealing ring and
- Fig. 4 shows a pipe section in section and top view with longitudinal sections in the area of the connection.
- Fig. 1 shows in section a section of two pipe sections 1, 2 of a combustible propellant charge sleeve made of one or more coils of textile threads which are connected with binders with propellant.
- These pipe sections 1, 2 are dimensionally stable and have a high mechanical strength.
- the pipe sections 1, 2 are plugged into one another, the outer surfaces of the two pipe sections 1, 2 merging into one another without attachment.
- the pipe section 1 has an outer constriction at its connection area, into which the connection area of the pipe section 2 is inserted.
- the two nested pipe sections 1, 2 are connected via a non-releasable snap connection.
- the snap connection consists of barbs 4 on the respective pipe sections 1, 2, which interlock and thereby result in a latching.
- annular, ie circumferential depressions or grooves 6 are arranged for receiving adhesive.
- FIG. 2 shows a section of an alternative pipe section 2 with rounded barbs 4.
- This pipe section 2 could be combined with the pipe section 1 according to FIG. H. get connected.
- the rounded barbs 4 make it easier to plug into one another.
- Fig. 3 shows an alternative embodiment with pipe sections 1, 2, which are inserted into one another and have a flat connecting surface 5.
- two radially circumferential sealing rings 7 are arranged on the connecting surface 5, which are each embedded in half in the two pipe sections 1, 2.
- several sealing rings 7 can also be used.
- Fig. 4 shows a tube section similar to Fig. 1 in section and top view.
- Essential to the invention are longitudinal sections 3 which extend in the axial direction in the region of the connection.
- An embodiment is shown with four longitudinal cuts 3, which are each arranged at an angle of 90 ° to one another. These longitudinal cuts 3 enable the pipe sections 1, 2 to be inserted into one another without cracks occurring.
- Blowing agents are understood to mean, in particular, high-energy substances according to DE 38 25 581 C1.
