Definitions

  • the invention relates to a magazine for caseless propellant charges for use in powder-operated setting tools, with plate or strip-shaped magazine bodies, the magazine body having passage openings which are surrounded by an annular bead forming a receptacle for the propellant charges and the outer contour of the annular bead at least partially away from the magazine body rejuvenated.
  • Caseless propellant charges have considerable advantages over the cartridges that are still common today. These advantages mainly consist in the much simpler manufacture and the resulting lower manufacturing costs. These advantages apply in particular to propellant charges without ignition charges. Such ignited propellant charges, however, lead to problems due to the not particularly good ignitability when used in setting tools. This is counteracted in known devices in that a small part is punched out of the propellant charge by means of an ignition pin and is brought to ignition in a blind hole with high compression. This type of ignition works relatively safely. However, the further burning off of the remaining propellant charge takes place poorly in these known devices. The cause of this phenomenon is that the outflow channels for the combustion gases leading away from the combustion chamber to the work space have a relatively small cross section and can be blocked by loose parts of the propellant charge. An enlargement of the cross section of outflow channels arranged in this way is problematic, since the insulation that is essential for maintaining the ignition would then no longer be guaranteed.
  • Magazines consisting of a strip-shaped magazine body with receptacles for the propellant charges.
  • the recordings are formed by an annular bead that tapers away from the magazine body.
  • the ring bead mainly takes over the sealing of the magazine against the closure parts on the device side.
  • axial discharge channels for the combustion gases are also required for the propellant charges arranged in such magazines, the disadvantages mentioned again occur.
  • An increase in the cross section of the axial outflow channels is not possible, since the propellant charges have to be supported in the axial direction for the reasons described.
  • the invention has for its object to provide a magazine for caseless propellant charges for use in powder-operated setting tools, which ensures simple and safe ignition and even burning of the propellant charges.
  • the annular bead has at least one outflow opening for the combustion gases that can be made to coincide with an outflow channel on the device side.
  • the combustion gases do not flow away from the combustion chamber in the axial but in the radial direction.
  • the cross section available over the circumference for the outflow ducts and the outflow openings in the magazine which can be brought into register with the outflow ducts can thus be kept considerably larger than in the case of an axial course, without impairing the insulation.
  • the propellant charge should be supported on all sides by device or magazine parts.
  • the outflow opening it is expedient to design the outflow opening as a hole passing through the annular bead.
  • the cross-sectional shape of the hole can be round, angular or a slot.
  • the hole should be offset in the axial direction with respect to the propellant charge, so that it is at most partially covered by the propellant charge.
  • grooves extending from the free end of the ring bead are also conceivable. This form of outflow openings is particularly suitable when the propellant charge, in powdery or still moist state, is finished pressed in the magazine itself in a manner known per se.
  • the outflow openings can be provided with a membrane that can be destroyed by the pressure of the combustion gases. These The membrane is only destroyed when the combustion pressure in the combustion chamber has reached a minimum value. Due to a membrane temporarily closing the outflow opening, the propellant charges in the magazine are also better protected against external influences, such as moisture or mechanical damage.
  • the annular bead has an elastic sealing lip for the closure parts on the device side in the area adjoining the outflow opening at the rear.
  • Such a sealing lip adapts to the device-side closure parts and is additionally pressed against the device-side parts by the gas pressure. The seal therefore gets better with increasing gas pressure.
  • the propellant charges are usually inserted into the magazine by machine. For the ignition to work properly, all propellant charges must be inserted equally far into the magazine. To make this possible, it is expedient to provide the ring bead on the inside with a stop shoulder for the propellant charge. Depending on the direction of insertion of the propellant charges into the magazine, the stop shoulder is arranged on the front or rear end of the receptacle.
  • the magazine is in itself a so-called disposable part, ie it is used only once and is subsequently removed.
  • An inexpensive material such as plastic, is therefore preferably used mainly for cost reasons. Since the temperatures when igniting a propellant charge are currently very high, but the entire ignition process takes only a fraction of a second, the temperature resistance of ordinary plastics is sufficient. In principle, however, it would also be possible to use the magazine several times, ie to refill it after use. In this case, materials can be used g s higher strength and temperature resistance, such aschtmetallegierun.
  • the magazine shown in FIGS. 1 and 2 consists of a strip-shaped magazine body, designated as a whole by 1, which has lateral transport catches la and passage openings 1b.
  • the passage openings 1b are surrounded by a total of 2 annular beads, which partially taper away on their outer side away from the magazine body 1.
  • Sleeveless propellant charges 3 with an H-shaped cross section are arranged in the receptacle of the annular beads 2.
  • the annular bead 2 is provided with lateral outflow openings designed as hole 2a. On its inside, the annular bead 2 has an elastic sealing lip 2b in the area adjoining the holes 2a.
  • the magazine shown in FIG. 1 is inserted into a setting tool, which is indicated as consisting of a barrel part, generally designated 5, a piston 6, and a closure part, generally designated 7.
  • the piston 6 is guided in a piston guide 5a of the running part 5.
  • the barrel 5 has at its rear end a receiving hole 5b for the annular bead 2 of the magazine.
  • At the bottom of the receiving bore 5b there is a blind bore designated as an anvil 5c.
  • the cross section of the anvil hole 5c is substantially smaller than that of the receiving bore 5b.
  • a closure part, designated overall by 7, interacts with the running part 5.
  • the closure part 7 has a pin 7a which projects into the annular bead 2 and supports the propellant charge 3 arranged in the magazine on one side.
  • the closure part 7 is provided with a guide bore 7b for an ignition pin which is axially displaceably mounted therein and is designated overall by 8.
  • the firing pin 8 has a conically tapering projection 8a at its front end. The cross section of the extension 8a is slightly smaller than that of the anvil hole 5c.
  • the firing pin 8 bounces against the propellant charge 3 by the force of an ignition spring or by the force of a hammer blow and thereby stamps out part of the propellant charge 3.
  • the punched-out part of the propellant charge 3 is compressed by the attachment 8a of the ignition pin 8 in the anvil hole 5c and thereby ignited.
  • the combustion spreads to the remaining propellant charge 3.
  • the combustion gases which are now developing come under high pressure through the outflow openings designed as hole 2a and the outflow channels 5d which can be made to coincide with the holes 2a into the working space 5e of the running part 5, where they act on the piston 6 and drive it away from the magazine.
  • the propellant gas losses are largely avoided by the sealing lip 2b cooperating with the pin 7a. Since the outflow channels 5d can be dimensioned relatively large, the flow losses occurring in the outflow channels 5d are also relatively small.
  • Both the magazine body 1 and the annular bead 2 are expediently made from a relatively inexpensive material such as plastic. If the magazine is to be used several times, however, metals such as aluminum alloys can also be used.
