Definitions
- the invention relates to an ignition of the propellant charge powder of a plastic cartridge, in particular for bolt-setting devices, according to the preamble of claim 1
- Such a cartridge according to the prior art is known from DE 44 44 095 C2.
- This consists of a cup-shaped base part, in which the propellant powder is arranged, and a cover, which consists of several layers. The firing takes place via a firing pin on an ignition set which is arranged between the layers of the cover
- the invention has for its object to improve an ignition for the propellant powder of a plastic cartridge according to the preamble of claim 1 so that it is fatigue-free in continuous operation
- this object is achieved in that the ignition is carried out by an electrical discharge or by laser light
- the ignition can have a direct effect on the propellant charge powder or can take place via an ignition charge.
- the propellant charge powder is advantageously one ignitable ignition set arranged in the cartridge, on which the ignition acts
- the ignition set can be arranged on the cover or on the edge of the cartridge between the base part and cover
- the ignition advantageously takes place via a high voltage generated, for example, by a piezoelectric stall
- the first pole of the ignition is expediently an electrically conductive tip pierced by the cover and the other pole is either a second electrically conductive tip or an adjacent metal block
- the ignition is advantageously carried out by laser light, specifically by a laser diode which is placed on the cover
- the ignition can usefully take place indirectly or directly
- Indirect ignition is characterized by the fact that the ignition takes place by thermal excitation of one or more additives (eg graphite) in the ignition charge or propellant powder, the additives having an absorption over a wide wavelength range
- the direct ignition is characterized by the fact that the ignition takes place by excitation of the molecules of the ignition charge or of the propellant charge powder, laser light being irradiated at precisely the wavelength which raises the molecules of the ignition charge or the propellant charge powder to the energy level from which the exothermic decay takes place
- FIG. 3 is an electrical ignition similar to FIG. 1, but here the ignition set is arranged in the middle of the cartridge,
- FIG. 4 is an electrical ignition similar to FIG. 3, but without ignition,
- Fig. 5 is ignition by laser light with a set of lights
- Fig. 6 is ignition with laser light without an ignition charge.
- the base part 2 has a circumferential collar, a starting set 4 being arranged between the base part 2 and the cover 3.
- the ignition takes place through the cover 3 with two tips 5, 6 made of electrically conductive material. At these tips 5, 6 a high voltage, for. B. created by a piezo crystal.
- an earthed metal block 7 is arranged below the collar and thus the primer 4.
- a tip can also be located on the metal block 7.
- the ignition set 4 is arranged in the middle of the cartridge.
- the Anzundsatz 4 z. B. in a plastic cartridge directly above the propellant powder 1 or be applied to this.
- no ignition set is used.
- Two tips 5, 6 are pushed directly into the cover 3 or through it into the propellant powder 1 and a discharge is brought about between them.
- laser light 9 ignites a starting set 4 (FIG. 5) through the cover 3 or directly the propellant powder 1 (FIG. 6).
- a laser diode 8 is preferably placed directly on the cover 3.
- the ignition can take place in two ways, depending on the wavelength of the incident light
- Laser light is radiated at precisely the wavelength which raises the ignition charge molecules (e.g. potassium benzanate) to the energy level from which the exothermic decay takes place (unimolecular, exothermic decay).
- ignition charge molecules e.g. potassium benzanate
