Definitions
- the invention relates to a powder-operated setting tool according to the preamble of Claim 1.
- a guide cylinder of a setting tool which has an inner bore and a cartridge bearing.
- a Driving piston axially displaceable. Contrary to the setting direction, it joins the Inner bore on the cartridge bearing in which a cartridge with, for example powdered propellant charge can be used.
- a cylindrical connecting channel whose diameter is smaller than the diameter of the cartridge storage.
- the connecting channel has one the mouth facing the cartridge storage, which is in the direction of the cartridge storage extended. The mouth is formed by an all-round phase.
- foil cartridges are not possible with this known setting tool, since the foil cartridge extends into the connection channel when the propellant charge is ignited expanded in the shape of a spherical cap and then bursts undefined. Get there Film residues in the inner bore of the guide cylinder and contaminate it, so that the setting tool malfunctions in a further sequence.
- the invention has for its object to a powder-powered setting tool create, with the propellant stored in foil cartridges without Malfunctions of the setting tool can be ignited easily and safely.
- the film cartridge is attached to one exactly defined point burst by tearing after being in the Foil cartridge a pressure necessary for the complete combustion of the propellant charge has built up.
- the second peripheral section acts against tearing the film and ensures that the one in the Connection channel protrudes, remains securely on the remaining part of the film and not in the Inner bore of the guide cylinder arrives.
- connection area between the torn or burst Foil section and the remaining part of the film is as large as possible preferably the second circumferential section at most over half the total circumference the mouth.
- the first The peripheral portion of the mouth is substantially U-shaped and the second Circumferential section formed straight.
- connection channel preferably the part of the mouth adjoining the mouth in the setting direction Connection channel a cross section deviating from a circular shape.
- the cartridge bearing 5 shown in FIGS. 1 and 2 closes against the Setting direction on an inner bore 2 of a guide cylinder 1.
- a driving piston 3 is arranged axially displaceable.
- the connecting channel 4 has a cartridge 9 facing the mouth 9, which consists of two Circumferential sections 10, 11 is composed.
- a first peripheral portion 10 is sharp-edged.
- a second circumferential section 11 has a radius provided, which is for example 0.5 to 4 mm.
- the first sharp-edged Circumferential section 10 and the adjoining wall of the Connection channel 4 are substantially U-shaped.
- the second, with one Radius provided peripheral portion 11 and the adjoining wall of the connecting channel 4 are rectilinear.
- the first peripheral portion 10 corresponds, for example, as shown in the exemplary embodiment according to FIG. 2, twice the second peripheral section 11.
- the cartridge store 5 there is a film cartridge 12, which with a powder propellant 13 is filled.
- the propellant charge 13 is ignited by means of two Electrodes 7, 8 between which an arc forms when the electrodes 7, 8 with an electrical power source, not shown, are connected and Current flows through the electrodes 7, 8.
- the two electrodes 7, 8 are fixed to one Housing 6 of a setting tool, not shown, connected and pierce the Bottom of the foil cartridge 12. This bottom, like the propellant charge 13 receiving area 15 of the film cartridge is formed from a thin-walled film.
- the one opposite the floor in the area of the mouth 9 of the connecting channel 4 arranged part of the film cartridge 12 is along the first, sharp-edged Torn peripheral portion 10 and protrudes as a tongue-shaped film residue 14 into the second circumferential section 11, which is provided with a radius Connection channel 4.
