Abstract
The invention relates to the igniting of the propellant charge powder (1) in a plastic cartridge, especially for bolt-firing tools. Said cartridge consists of a cup-shaped base part (2) with a cap (3), the propellant charge powder (1) being located in the base part (2). According to the invention, the propellant charge powder is ignited by an electrical discharge or by laser light (9) to ensure continuous fatigue-proof operation.
Description
Technical field
The present invention relates to a kind of sparking gear that is used for ail gun plastic cartridge casep propellant powder.
Background technology
So far at the ail gun cartridge case that is commercially available solid chemicals (emission medicinal powder) is produced reaction as propellant powder and by mechanical energy transmission (impacting nail bump ignition medium).Impacting that the required energy consumption of langrage spring regarded as by the ail gun producer is to allow the thing of people's fatigue in continuous operation.
DE4444095C2 discloses this cartridge case that belongs to prior art, and it comprises part of the cup-shaped end and the lamination closing cap of wherein placing propellant powder.Sparking gear works by the impact nail that affacts on the ignition part, and the part of wherein getting angry is arranged between the sealing cap rock.
Summary of the invention
The objective of the invention is to be, the sparking gear of plastic cartridge casep propellant powder is improved, make its continuous operation not tiredly.
The object of the present invention is achieved like this, this sparking gear that is used for ail gun plastic cartridge casep propellant powder, and wherein cartridge case comprises the part of the cup-shaped end with closing cap, and propellant powder is arranged in the end part, and wherein sparking gear works by discharge or laser beam.
Described sparking gear can not worked in two ways not tiredly.
Sparking gear can directly affact on the propellant powder or by the ignition part and work.Useful to this is that the ignition part of propellant powder igniting is arranged in the cartridge case, and sparking gear works to it.
The part of getting angry can be arranged on the closing cap or be arranged on cartridge case edge between end part and the closing cap.
In first advantageous embodiments, sparking gear is preferably by working as the high voltage that is produced by piezo-electric crystal.
First utmost point of described sparking gear on purpose is designed to protrude into the conductive tip of closing cap and another utmost point or second conductive tip or adjacent metal piece.
In another advantageous embodiments, sparking gear preferably by laser beam, promptly works by the laser diode that is contained on the closing cap.
Meaningfully sparking gear can be acted on indirectly or directly.
Sparking gear is characterised in that indirectly, and sparking gear works by thermal excitation one or more additives (as graphite) in ignition part or propellant powder.Wherein additive has the absorption of wide wave-length coverage.
Directly sparking gear is characterised in that, sparking gear is got angry the molecule of part or propellant powder and worked by exciting, and wherein laser is with wavelength illumination accurately, gets angry the energy level that part or propellant powder molecular heat decomposes to improve.
With reference to the accompanying drawings further feature of the present invention is described.

The description of the specific embodiment
Fig. 1 shows the plastic cartridge casep that comprises part 2 of the cup-shaped end and closing cap 3, places propellant powder 1 in its end part 2.End part 2 has annular rim, and ignition part 4 wherein is set between end part 2 and closing cap 3.Sparking gear works by the closing cap with two tips 5,6 of being made by conductive material.On most advanced and sophisticated 5,6 as by piezo-electric crystal, form high voltage.In Fig. 2, in the position at Fig. 1 second tip 6 and be positioned at annular rim and it is got angry and a grounded metal piece 7 is set under part.On metal derby 7, also a tip can be set.
In the embodiments of figure 3, ignition part 4 is arranged on the middle part of cartridge case.The part 4 of getting angry can for example be set directly on the propellant powder 1 of plastic cartridge casep or dress thereon.
In the embodiment of Fig. 4, adopt the ignition part, two tips 5,6 directly contact or pass it with closing cap 3 and contact with propellant powder 1, produce discharge betwixt.
Wherein two of sparking gear types depend on the irradiation light wavelength:
1, indirectly by one or more additives of thermal excitation (as graphite), it has the absorption of wide wave-length coverage.This ignition part that is called behind the ignition particle is got angry.
2, directly excite the molecule of ignition part, by having the laser irradiation of accurate wavelength, it has improved the energy level of the thermal decomposition (unimolecule thermal decomposition) of ignition part (as Kalium-Benzanat).
