Definitions

  • the invention relates to a powder-operated setting tool with a handle having housing, a piston guide which acts against the force of a spring and is axially displaceable relative to the housing and one is opposite to the setting direction to the piston guide, the ignition pin guide, which is opposite the housing is axially displaceable and cooperates with a damping device which is located on one of the Supporting stop surface of the housing facing.
  • An Indian Firing pin guide arranged firing mechanism has one against the force of a Spring element axially displaceable ignition pin.
  • the ignition pin becomes accelerated and ignited by the prestressed spring element in the direction of the propellant charge this when hitting it.
  • the LPG pressure accelerates the piston guidance and the ignition pin guide against the setting direction and a driving piston in one Guide bore of the piston guide in the setting direction, so that the driving piston is in area of the piston guide on the setting direction side drives the recording material.
  • the acceleration of the piston guide and the ignition pin guide against the setting direction relative to the housing is by the damping device subdued.
  • the invention has for its object to a powder-operated setting tool of the generic type create that, regardless of the amount of pressure, a safe operation of the Damping element ensures that the operator offers a high level of comfort and is simple and economical to manufacture.
  • the object is achieved in that the housing is one of the Guide the piston guide serving receiving space, the axial length the piston guide, at most, that of the end faces of the housing on the setting direction and the firing pin guide corresponds to the limited axial length of the receiving space.
  • the receiving space receiving the piston guide has an axial length that itself from a setting direction side of the housing to the setting direction side Front side of the firing pin guide extends.
  • the axially in the receiving space displaceable piston guide is at most of the same length as the receiving space.
  • the firing pin guide When the firing pin guide is closing the arranged on the piston guide Cartridge holder should serve, then preferably corresponds to the axial length of the Piston guide of the axial length of the receiving space.
  • the piston guide In the pressed state of the Of the setting tool, the piston guide lies against the ignition pin guide without the damping device squeeze.
  • An approximately constant damping force is preferably achieved with a damping device achieved by a cylinder containing liquid medium under gas pressure and a pressure piston having throttle openings is formed.
  • the effect is expedient Pressure piston with the ignition pin guide and the cylinder with the stop surface of the Housing together.
  • the invention is based on a drawing that shows an embodiment, explained in more detail.
  • the setting tool according to the invention shown in the rest position serves to drive in Fastening elements 21, for example nails, bolts or the like.
  • hard receiving materials 22 has a housing 1 with a laterally protruding handle 2, a arranged in the handle 2 operating switch 3, a piston guide 4 with a Guide bore 5 in which a driving piston 6 is displaceable and one against the Direction of setting to the piston guide 4, the ignition pin guide 8 an ignition mechanism 9, with the piston guide 4 and the firing pin guide 8 opposite the housing 1 are axially displaceable.
  • the firing pin guide 8 is displaceable against the force of a restoring element 10 is supported on a stop surface 7 of the housing 1 facing the setting direction.
  • a Cartridge receptacle 11 At one end area of the piston guide 4 facing the ignition pin guide 8 there is a Cartridge receptacle 11 arranged to accommodate a propellant charge, not shown serves.
  • the ignition mechanism 9 is composed of an ignition pin 12, a surrounding the ignition pin 12, laterally from this protruding driving cam 13 and a spring element 20 together.
  • the driving cam 13 protrudes into the axial projection in the Firing pin guide 8 mounted, cooperating with the piston guide 4 driving pin 14.
  • a driver 15 protrudes laterally from the firing pin guide 8 and leads into the axial projection of a pressure piston 16, not shown, having throttle openings Damping device 17 protrudes, which is arranged laterally next to the ignition pin guide 8.
  • the damping device 17 has a cylinder 18 in which the pressure piston 16 is mounted. Inside the cylinder 18 is under gas pressure standing, liquid medium 19.
  • the damping device 17 is supported, as is the reset element 10 and that with the ignition pin 12 cooperating spring element 20, on the stop surface 7 of the housing 1.
  • the fastening element 21 to be driven is inserted into the setting direction End of the piston guide 4 inserted and the setting tool in a ready to ignite Positioned.
  • the one between the piston guide 4 and the driving cam 13 of the firing pin 12 arranged driving pins 14 pushes the firing pin 12 into a position ready for ignition, with the Firing pin 12 cooperating spring element 20 is compressed.
  • the piston guide 4 In the pressed position, the piston guide 4 is on the ignition pin guide 8 and the Ignition pin guidance on the damping device 17.
  • the ignition pin 12 moves out of the axial projection of the driving pin 14 and is accelerated towards propellant where he ignites it.
  • the propellant pressure accelerates the propellant piston 6 in the Guide bore 5 of the piston guide 4 in the setting direction and the piston guide 4 and the firing pin guide 8 against the setting direction. That in the setting direction area of the setting device arranged fastening element 21 is from the driving piston 6 driven into the receiving material 22.
  • Right at the start of the acceleration of the Firing pin guide 8 responds to the damping device 17, so that the force of the recoil is damped so strongly that there are no major burdens on the Operator act.
  • the reset element 10 acting in parallel with the damping device 17 in the form of a Compression spring arranged between the ignition pin guide 8 and the stop surface 7 is, the ignition pin guide 8 pushes into its starting position after the driving-in process until it touches one between the piston guide 4 and the ignition pin guide 8 arranged stop of the housing 1 abuts.
  • the one with the firing pin guide 8 cooperating damping device 17 can also be in their starting position reach.
