Definitions

  • the invention relates to a device for igniting a propellant charge, in particular for nail guns or setting tools, with a housing in which a cavity is formed, a displaceably guided piston in the cavity for compressing gas (air) in the cavity and one with the cavity via an opening connected chamber in which a propellant charge is arranged, which can be ignited by compression of gas when the piston is displaced.
  • Propellant charges can be ignited electrically or by mechanical or thermal action.
  • a firing pin strikes the sleeve body containing the propellant charge, in which the ignition charge upstream of the propellant charge is heated and ignited by the particles rubbing against each other.
  • the disadvantage of igniting a propellant charge using a firing pin is the errosive load and contamination of the barrel due to the friction agents present in the primer charge.
  • Advantages here are adiabatic ignition, in which the propellant charge is ignited by an ignition charge, which in turn is initiated by heat generated as a result of adiabatic compression of air or gas.
  • a device for adiabatic ignition of a propellant charge is known from DE-OS 21 03 253.
  • the known device has a housing in which a (cylindrical) cavity is formed.
  • a spring-loaded piston for compressing the gas located in the cavity is arranged in the cavity.
  • a barrel is included, in whose end section facing the cavity (cartridge chamber) a sleeve-free projectile is arranged with a chamber open towards the cavity for receiving the propellant charge.
  • the cross-sectional area of the cartridge chamber is relatively large compared to the cross-sectional area of the cavity. The force that acts on the piston located at its bottom dead center when the propellant is burned is thus relatively large. Because of this force, the piston is moved back against the spring, so that the gas generation when the propellant charge is ignited is only insufficiently converted into a forward movement of the projectile.
  • An initialization device for activating an aircraft crew rescue system is known from US Pat. No. 4,856,433.
  • a gas-generating charge is ignited in the initialization device. By the rising The rescue system is activated by pressure.
  • the gas-generating charge is ignited by adiabatic compression.
  • the channel leading from the compression space to the propellant charge has a relatively large cross-sectional area.
  • the invention has for its object to provide a device for igniting a propellant charge of the type mentioned, in particular for nail guns or setting tools, in which evasion of the gas pressure upon ignition of the propellant charge in the cavity is largely prevented.
  • the opening connecting the cavity and the chamber is designed as a nozzle with a cross-sectional area many times smaller than the cavity, the piston or the chamber and that the nozzle is arranged by an ignition plate arranged in the chamber is covered for the propellant charge, the thickness of the ignition plate in the area of the nozzle and around it being less than in the rest of the area of the ignition plate.
  • a nozzle with an extremely small cross-sectional area is located between the cavity and the chamber for the propellant charge compared to the cavity or chamber cross-sectional area. Because of this extremely small cross-sectional area, the chamber on its wall provided with the nozzle can be regarded as practically closed; the gas in the combustion of the propellant charge can only escape to a very small extent into the cavity. Due to its small cross-sectional area, the nozzle acts like a throttle backflow of (combustion) gases into the cavity is virtually prevented.
  • the cross section of the nozzle is in any case significantly smaller than that of the at least one outflow opening, through which the combustion gases are to emerge when the propellant charge is ignited, in order, for example, to advance the thrust piston in a nail gun or setting tool.
  • the nozzle opening is covered by an ignition plate arranged in the chamber, the thickness of which is less in the area of the nozzle opening than in the rest of the area.
  • the ignition plate preferably consists of a sensitized ignition material, in particular sensitized nitrocellulose.
  • the ignition plate is thinner in its area subjected to mechanical thermal stress, namely in the area of the nozzle opening and around it, so it responds more in the area subjected to mechanical thermal stress. In this area of low thickness, the (hot) compressed gas causes the ignition plate to fragment.
  • the ignition plate breaks, an increase in the surface area of the ignition material is associated, so that lower gas temperatures and lower compression pressures are sufficient for ignition.
  • the ignition plate has a relatively small thickness only in the area of the nozzle opening, ie not over its entire cross-sectional area, but is relatively thick in the remaining area. An ignition initiated in relation to the ignition plate in its thermally mechanically stressed area thus spreads rapidly over the ignition plate, the marginal regions of the ignition plate being two to six times thicker providing sufficient ignition energy to ignite the propellant charge.
  • the cartridges can also be reliably ignited adiabatically in devices with small compression volumes, i.e. in devices with relatively small piston diameters and comparatively short compression strokes.
  • the adiabatic ignition device for propellant charges according to the invention is characterized by a nozzle or throttle with an extremely small cross-section and the connection of the propellant charge to the nozzle via the specially designed ignition plate with a reduced thickness in the region of the nozzle.
  • the igniter plate preferably extends over the entire cross-sectional area of the chamber, so that in addition to the region of reduced thickness there is also an area in terms of area and volume in which the igniter plate has a greater thickness.
  • the ignition plate advantageously has a thickness of 1/3 to 1/2 mm in its thinned area.
  • the thickness of the igniter plate in the area of the nozzle and around it is about 1/6 to 1/2 of the maximum thickness of the igniter plate.
  • the ignition plate is preferably provided on one side with a flat surface with which it rests on the wall provided with the nozzle and separating the chamber and the cavity, the surface on the side of the ignition plate facing away from the cavity having a preferably central recess and with the propellant charge is in contact.
  • the reduced thickness of the ignition plate is advantageously achieved by recesses on both sides, preferably equally deep and central. In the case of an ignition plate designed in this way, it no longer matters how it is inserted into the chamber or into a cartridge sleeve.
  • the ignition plate is frictionless.
  • friction material in the form of glass powder or the like is added to the ignition material of the propellant charge.
  • the friction agent is released and flung away, causing signs of erosion and contamination in the barrel area near the chamber.
  • the ignition plate of the device according to the invention can also be ignited due to its special design described above without friction.
  • the ignition plate has a 6 times lower sensitivity to friction and about 5 times less impact sensitivity than conventional ones with a friction agent provided ignition plates. This is particularly advantageous when used in nail guns or setting tools and the associated rough handling on construction sites.
  • the ignition plate preferably consists of a material based on nitrate cellulose, to which tetrazene has been added as a sensitizer.
  • the ignition plate is burned with low levels of pollutants, since the ignition plate has no heavy metals.
  • a sleeve body containing the propellant charge is arranged in the chamber, which has a bore aligned with the nozzle in its bottom wall, the ignition plate being arranged in the sleeve body between the propellant charge and the bottom wall.
  • the igniter plate is preferably held pressed against the bottom wall by an annular bead of the sleeve body.

  • the piston which is preferably biased by a spring, is immersed with its front end in the recess, the conical surface resting on the surface of the recess.
  • the piston is preferably provided at its front end with a pin which is immersed in the nozzle opening at the bottom dead center of the piston. As a result, the gas or air is also compressed in the nozzle duct, which represents a dead space in terms of compression.
  • the invention provides a device for igniting a propellant charge as a result of adiabatic compression of air or gas in a cavity, in which the igniter plate igniting the propellant charge is ignited without contact.
  • the nozzle which acts as a throttle when the propellant charge explodes and connects the cavity to the chamber has a diameter which is in the range of a few millimeters, while the diameter of the cavity is at least a factor of 10 larger.
  • the invention further relates to a cartridge, in particular for nail guns or setting tools, with a sleeve body which has a closed bottom wall, a propellant charge introduced into the sleeve body and a cover for the propellant charge on the side facing away from the bottom wall.
  • the invention Cartridge is characterized in that a bore is formed in the bottom wall of the sleeve body, which is covered by an ignition plate arranged in the sleeve body and which can be ignited by heat due to gas compression, the thickness of which in the area of the bore and around it is less than in the rest of the area Ignition plate, the thickness of the ignition plate in the diluted range being 1/2 to 1/6 of the other thickness of the ignition plate.

  • the magazine according to the invention is characterized in that a magazine band made of plastic is provided, which connects the cartridges to one another and forms their bottom walls, the magazine having at least one predetermined breaking point per cartridge in the area of the bottom walls of the cartridges, that an ignition plate is provided per cartridge, which is arranged on the magazine belt in the area of the bottom wall of the cartridge, and that the ignition plate is thinner in the area of the predetermined breaking point than in the rest of the area, the thickness in the thinned area preferably being 1/2 to 1/6 of the maximum thickness of the ignition plate.
  • Each of these predetermined breaking points is preferably designed as a through-hole made in the magazine band, which is covered with a thin plastic film.
  • the predetermined breaking point can also be designed as a (pocket) bore, the depth of which is slightly less than the thickness of the magazine band, so that the bore is closed by a "plastic skin" integral with the magazine belt.

Because of the low mass in this area, the ignition plate 70 partially heats up to above the auto-ignition temperature. The ignition of the ignition plate 70 initiated in the mechanically and thermally stressed central region is transferred to the thickened edge region, so that an ignition flame is formed, the energy of which is sufficient to ignite the propellant charge 76.

At this moment, the bores 42 and 66 act like a throttle, which makes it difficult for the combustion gases to flow back into the cavity. Since the total flow channels 56 have a substantially larger cross-sectional area than the bore 66 or 42, the combustion gases flow out for the most part via the flow channels 56; almost the entire combustion gas pressure is converted into a forward movement of the feed piston 48.
