Definitions
- the invention relates to the connection of pipe sections of combustible propellant charge sleeves.
- DE-A-30 34 360 (corresponds to GB-A-2 194 024) shows a connection of pipe sections combustible propellant charge sleeves, the pipe sections to be connected are inserted into each other and the nested pipe sections over a non-releasable snap connection are connected.
- DE-A-30 34 360 does not show that the propellant charge sleeve consists of one or more There is winding of textile threads, which are connected with binders with blowing agents and the propellant charge sleeves are dimensionally stable and have a high mechanical strength exhibit.
- the invention relates to the connection of combustible pipe sections
- Propellant sleeves made of one or more wraps of textile threads, with binders are connected, the binders containing blowing agents.
- These propellant charge cases are in contrast to those of DE 30 34 360 A1 dimensionally stable and have a high mechanical strength.
- So z. B. the tensile strength at the same Wall thickness of the sleeve, compared to the sleeve according to DE 30 34 360 A1, by the Factor 40 - 56 higher.
- Such a propellant charge sleeve is described in the generic DE 38 25 581 C1. This describes a connection of pipe sections of combustible propellant charge sleeves from one or more wraps of textile threads with binders are connected with propellant and the propellant charge sleeves are dimensionally stable and a have high mechanical strength.
- EP-A1-0 684 443 and FR-A-2 711 209 each show a connection of pipe sections via an additional part pushed on from the outside.
- the invention is based on the task of connecting pipe sections combustible propellant charge sleeves, which consist of one or more wraps of textile threads, which are connected with binders with blowing agents and which are dimensionally stable and have a high mechanical strength.
- These propellant charge cases are needed, e.g. B. to build ammunition, to attach the Projectile or to hold the combustible part with the metallic Bottom piece that receives the ignition and the sealing of the hot steam takes over to the cartridge chamber when the propellant powder burns.
- this object is achieved by the features of claim 1, d. H. the pipe sections to be connected are inserted one into the other, the one inside the other inserted pipe sections connected via a non-detachable snap connection are, and at least one in the axial direction on the pipe sections Connection extending longitudinal section is arranged.
- the pipe sections are locked by barbs.
- the barbs can have a cross section such. B. rectangular contour or preferably have a rounded cross-section. This makes it easier Insert the two pipe sections into each other.
- Adhesive applied.
- an adhesive curable multi-component systems e.g. B. based on polyurethane or Epoxy resins used.
- connection is preferably used for ammunition components and ammunition cases.
- Fig. 1 shows in section a section of two pipe sections 1, 2 of a combustible Propellant charge sleeve made of one or more winding textile threads with Binders are associated with blowing agents.
- These pipe sections 1, 2 are dimensionally stable and have a high mechanical strength.
- the pipe sections are for connection 1, 2 inserted into each other, the outer surfaces of the two pipe sections 1, 2 merge into one another without starting.
- the pipe section 1 points to this Connection area an outer constriction 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 locking.
- On the connecting surface 5 of the two pipe sections 1, 2 are annular, d. H. circumferential depressions or Grooves 6 arranged for receiving adhesive.
- Fig. 2 shows a section of an alternative pipe section 2 with rounded Barb 4.
- This pipe section 2 could be connected to the pipe section 1 according to FIG. 1 combined, d. H. get connected. Due to the rounded barb 4 is a Interlocking made easier.
- Fig. 3 shows an alternative embodiment with pipe sections 1, 2, which are nested are and have a flat connecting surface 5.
- two radially circumferential sealing rings 7 To be locked arranged on the connecting surface 5 two radially circumferential sealing rings 7, the half embedded 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 are in the axial direction in the area of the connection extend. An embodiment is shown with four longitudinal sections 3, each in are arranged at an angle of 90 ° to each other. Allow these longitudinal cuts 3 the insertion of the pipe sections 1, 2 without cracks.
- blowing agents are in particular high-energy substances according to DE 38 25 581 C1 understood.
