Definitions

  • the invention relates to a powder-operated bolt setting device according to the preamble of claim 1.
  • the object of the invention is a powder-operated bolt-setting tool to create according to the preamble of claim 1, the construction is simplified.
  • An air cushion is used to reset the piston, that is between the piston head and the barrel on the muzzle side End of the barrel guide hole for the piston head forms.
  • This air cushion not only catches the piston, but also acts like an air spring, because the pressure behind the piston is released by appropriate ventilation slots tends to drop in the barrel rather than the pressure of the air cushion.
  • Fig. 1 shows sections of the section on the barrel side of a powder-operated bolt-setting tool in its initial position.
  • FIG 2 and 3 show the detail of the bolt gun the bolt setting process or at the end of the bolt setting process.
  • the powder powered bolt gun shown includes a barrel guide sleeve 1, the mouth side of a sleeve-shaped insert 2 records.
  • the insert 2 takes a slidable therein Bolt guide 3, which is provided with a shoulder 4, which in the starting position of Fig. 1 on an inward flange portion 5 of a screwed on the muzzle on the barrel guide sleeve 1 Threaded piece 6 rests.
  • a coil spring 9 is clamped prestresses the bolt guide 3 in the starting position of FIG. 1.
  • the bolt guide 3 has a bore 10 for receiving a to be set bolt, which extends on the side facing away from the mouth is displaceable around the mouth end of a barrel front part 11 record during use 2 as a safety stop for the barrel front 11 is used when the device is operated without loading a bolt should be.
  • a rear barrel part 12 is provided, which with a Extension 13 inserted into the barrel front part 11 and in which a piston receptacle 14 and a combustion chamber adjacent to a conical tread 15 is formed.
  • a cartridge bearing 16 is provided for receiving a cartridge, with the Cartridge bearing 16 has a narrowing bore opening into the running floor 15 17 connects.
  • a cartridge is located adjacent to the cartridge store 16 Closure piece 18 having a cartridge band guide.
  • the rear barrel part 12 is via one or more tie rods 19th connected to the bolt guide 3 such that the distance between the two within predetermined limits determined by an axial groove 20 be in which the mouth end of the pull rod 19 slidably is, may vary.
  • the pull rod 19 advantageously has hook-shaped ends with which they into the axial groove 20 or a corresponding Recess is mounted on the barrel rear part 12.
  • a piston 21 is also provided, which has a piston head 22 and has a piston shaft 23.
  • the piston skirt 23 is up to the mouth side the bore 10 of the pin guide 3 is displaceable (Fig. 3).
  • the Piston head 22 has a section 24 which is in the starting position is received by the piston receptacle 14 of the rear barrel part 12, and a section 25 with an enlarged diameter by the barrel guide bore 26 of the barrel front part 11 is guided.
  • the piston 21 has a transition piece a conical mouth-side end 27, which has a conical receptacle 28 is assigned at the mouth end of the barrel front part 11, and one adjoining cylindrical section 29 adjacent to Section 25.
  • a damping disk 30 can be arranged his.
  • the barrel front part 11 is on its with the barrel rear part 12 engaging end with several, distributed over its circumference Vent slots 31 provided in the starting position of FIG. 1st are practically covered by the section 25 of the piston 21.
  • the ventilation slots 31 open into a by a twist 32 at the end of Barrel front part 11 formed and surrounded by the barrel guide sleeve 1 Annulus.
  • the barrel guide sleeve 1 has corresponding ventilation openings 33 provided so that the ventilation slots 31 with the outside are connected.
  • the bolt guide 3 takes a corresponding one for setting the bolts Bolt (not shown).
  • the bolt gun is on a Wall or the like, in which the bolt is to be placed, placed and brought into firing position by pressing against the wall (Fig. 2).
  • the bolt guide 3 against the force of the coil spring 9 in the barrel guide sleeve 1 until the coil spring 9 is compressed, indented so that barrel front part 11 and barrel rear part 12 backwards are moved so that the cartridge bearing 16 receives a cartridge and is brought into the firing position with respect to the closure piece 18.
  • the ventilation slots are 31 already released for the escape of combustion gases, so that the piston back is connected to the outside, reducing the pressure falls behind the piston 21 accordingly. This release then takes place when the portion 24 of the piston head 22 emerged from the rear barrel 12 and the piston 21 is accelerated accordingly.
  • the volume of air compressed in the annular space 34 is due to the sealing of the annular space 34 by the section 25 of the piston 21 opposite the barrel guide bore 26 and through the piston skirt 23 and the adjoining conical section 27 on the outlet side of the barrel front part 11 is built up and intercepts the piston 21.
  • the volume of air compressed in the annular space 34 expands due to the pressure drop on the back of the piston thereby returning the piston 21 to its initial position in which the section 24 of the piston head 22 is received by the barrel rear part 12 and the portion 25 of the piston head 22 adjacent to the barrel rear part 12 is located.
  • Leakage losses on the sealing surfaces must of course be so low be held that the air volume acting as an air spring is sufficient Force can be applied to the piston 21 in its initial position attributed.
