Definitions

  • the invention relates to a powder-operated setting tool according to the preamble of Claim 1.
  • Such a setting tool with the type designation DX A40 is produced for example by Hilti AG in Liechtenstein.
  • This well-known setting tool has a guide cylinder which can be moved relative to a housing and has an inner bore on, in which a driving piston is axially displaceable.
  • Towards one A control pin protrudes from the end region of the guide cylinder pointing in the setting direction when pressing the setting tool against a surface together with the Guide cylinder is offset against the setting direction.
  • a trigger slide which is essentially when a trigger is actuated is displaceable perpendicular to the setting direction.
  • the firing pin is rotated about its longitudinal axis so that its counter surface is displaced from the axial projection surface of the control pin.
  • the ignition pin is accelerated in the setting direction up to it hits the ignition area of a cartridge and ignites it.
  • the firing pin will pressed laterally against the control pin via a return spring. Only when lifting the Setting tool from the ground, the guide cylinder is biased by a The spring has been pushed into its initial position on the setting direction.
  • the control pin moves also in the setting direction.
  • the control pin gives the ignition pin while still of the lifting process freely, so that its counter surface with the help of the return spring can in turn be turned back into the axial projection of the control pin.
  • a setting tool according to the preamble of claim 1 is from GB 1 163 061 A. (01) known.
  • the invention has for its object to a powder-powered setting tool create that an operator reaching a certain level of pollution in one from the bottom of the inner bore and one against the The combustion chamber formed thereby facing the end face of the driving piston indicates that the setting tool can no longer be operated and must therefore be cleaned.
  • the game is advantageously less than 2 mm.
  • the degree of contamination can be set within the combustion chamber preferably the game adjustable.
  • the smallest is expediently used for simplified manufacturing reasons Distance between the retaining pin and the free end of the control pin adjustable.
  • the setting is made, for example, by means of a threaded connection between the Control pin and the guide cylinder. For example, if you turn the control pin out of the Guide cylinder out a little, so even with a little dirt Ignition pin can no longer be placed in a position ready for ignition. Will the tax pen something turned out of the guide cylinder, so the degree of contamination to be taller.
  • This threaded connection has the further advantage that the setting of the Game can not be adjusted from the outside.
  • the setting or correction of the game can, for example, only with a service if the setting tool is disassembled will be made.
  • a powder-operated setting tool such as a housing 1, a guide cylinder 2 with an inner bore 25, a driving piston 4, a control pin 8, an ignition pin 16, a trigger slide 19 and a trigger 15.
  • the guide cylinder 2 protrudes into the housing 1 and is opposite to this Setting direction against the force of a spring 10 displaceable.
  • the driving piston 4 is located in an inner bore 25 of the guide cylinder 2, which point in the setting direction Bottom 28 has a connecting channel that opens up to one Cartridge receptacle 7 of the guide cylinder 2 extends.
  • a guide tube 3 which extends in the setting direction sleeve-shaped damping element 11 is supported on the closure 12.
  • the guide tube 3 projects beyond the closure 12 in the setting direction and has a central through hole with a receiving area open in the setting direction for a nail-shaped Fastening element 24.
  • the closure 12 projects beyond the guide cylinder 2 in radial direction.
  • Surrounding the spring 10 cooperating with the guide cylinder 2 the guide cylinder 2 and is between an annular pointing in the setting direction Shoulder of the housing 1 and one pointing against the setting direction annular shoulder of the closure 12 is arranged.
  • the driving piston 4 is composed of a head 6, whose diameter in essentially corresponds to the diameter of the inner bore 25 and one in the setting direction to the head 6 adjoining shaft 5, the diameter of which is smaller than that Diameter of the head 6.
  • the central through hole of the guide tube 3 has a section serving to guide the shaft 5, its diameter corresponds essentially to the diameter of the shaft 5.
  • a retaining pin 9 is arranged in the end region of the housing 1 on the setting direction, which passes through a longitudinal slot of the guide cylinder 2, into the inner bore 25 of the Guide cylinder 2 protrudes and can be brought into operative connection with the driving piston 4.
  • a control pin 8 opposite the setting direction protrudes from the guide cylinder 2, a control pin 8, the together with the guide cylinder 2 is displaceable relative to the housing 1.
  • This Control pin 8 is adjustable by means of a threaded connection 27 with the guide cylinder 2 in connection.
  • a smallest distance A1 between the retaining pin 9 and the free end of the control pin 8 plus a game S corresponds to a smallest Distance A2 between the retaining pin 9 and the counter surface 26 of the ignition pin 16.
  • the ignition pin 16 is when pressing the setting tool against a base 23, according to FIG. 2, relative to the housing 1 from a setting direction side Starting position counter to the force of a spring element 18 the setting direction in a position ready for ignition.
  • the spring element 18 biased and the driver 17 of the firing pin 16 comes into the recess a trigger slide 19.
  • the firing pin 16 is triggered with the aid of a trigger 15, the trigger lever 22 of the trigger slide 19 when the trigger 15 is actuated shifts perpendicular to the setting direction.
  • the trigger slide 19th cooperating spring member 20 biased.
  • the one in the recess of the release slide 19 positively guided driver 17 of the ignition pin 16 is from the axial projection surface of the control pin 8 offset and the ignition pin 16 of the Spring element 18 accelerates in the setting direction until the firing pin 16 in an ignition area opens a cartridge and ignites it.
  • the driver 17 tensions a return spring 21 before, which pushes the driver 17 laterally against the control pin 8.
  • a displacement of the driver 17 from and into the axial projection surface of the Control pin 8 is, for example, by turning the ignition pin 16 around its Longitudinal axis reached.
  • Fig. 4 discloses contamination with the thickness A at the bottom of the inner bore 25 of the guide cylinder 2. This contamination is caused, for example, by unburned powder residues.
  • the guide cylinder 2 When the guide cylinder 2 is displaced in the setting direction, it cannot quite reach its initial position due to the contamination.
  • the control pin 8 arranged on the guide cylinder 2 cannot release the driver 17 of the ignition pin 16, so that it cannot be moved into the axial projection surface of the control pin 8.
  • the control pin 8 does not move the ignition pin 16 into an ignition-ready position.
  • a cartridge channel 13 extends perpendicular to the setting direction through the setting device, in which a strip-shaped cartridge magazine 14 is arranged.
