Definitions

  • the invention relates to a bolt-driving tool for driving bolts or the like into components with an interception device for the driving piston according to the preamble of Claim 1.
  • bolt setting devices are often included intermediate driving piston used.
  • the one required for the collection work Energy is generated, for example, from a powder charge in a cartridge won.
  • the primary energy of the ignited powder charge is called kinetic energy of the driving piston, which finally pushes the bolt into the ground.
  • kinetic energy of the driving piston At only a partial utilization of the kinetic energy of the driving piston is required Excess energy can be intercepted without damaging the driving parts. Since components are known to have very different strengths, must be used when using fasteners with a relatively high energy surplus be counted.
  • the sudden impact caused by energy degradation the driving piston and the components of the piston that interact with the piston Device can lead to significant device malfunctions, which adversely affect the Impact of the tool setting tool.
  • the excess energy is dissipated outside the device.
  • the driving piston emerges from the barrel mouth of the device emerge and with the component into which the bolt is to be driven in Active connection can occur.
  • the driving piston therefore performs one outside the bolt-setting tool Deformation work. This constructive measure will be within the Device arranged starting shoulders and the like. Less stressed. For that it loses Bolt gun but its advantage, regardless of the strength properties of a Component, always to achieve a uniform penetration depth of the set bolts. Rather, the opposite is the case, and the bolts are depending on the strength of the Component driven deeper or less deep into the component. With a soft component this can result in the driven bolt even passing through the back of the Component emerges again.
  • a second category of bolt-operated tools provides for the excess energy in the Dismantle the interior, between the elements of the bolt gun itself. This happens for example with the help of plastically or elastically deformable components that between two device parts movable relative to each other are arranged.
  • DE-A-1 478 838 discloses a bolt-setting tool at the one between the driving piston and a pin guide with the driving piston in A sleeve-shaped pressure piece that can be brought into an active connection and an elastic one Buffer element are arranged, the remaining excess energy of the driving piston absorbed during a setting process.
  • the pressure piece has a stepped Outside diameter and protrudes into a mounting hole in the bolt guide.
  • the Buffer element is on the smaller diameter extension of the outside diameter stepped pressure piece stored and is supported against the setting direction of a shoulder of the pressure piece and in the setting direction on an annular counter surface of the Bolt guide from. So that the pressure piece is movable relative to the pin guide, there is a massive game between the two moving parts. Get lost Annular gaps between the pressure piece on both axial sides of the buffer element and the bolt guide. When compressing the buffer element, this can be in the annular gaps between the inner wall of the bolt guide and the outer wall of the pressure piece. This can jam the movable Guide parts and cause failure of the fastener driving tool.
  • the object of the present invention is therefore to provide a setting tool of the generic type to be improved so that jamming of the moving parts is prevented.
  • the principle of energy dissipation within the device should be maintained can.
  • the constructive elements should be simple and possibly also one Allow retrofitting of existing setting tools of the generic type.
  • the solution to these tasks consists in a bolt-setting tool with the characteristic in Features of claim 1.
  • Advantageous versions and / or further developments of the invention are the subject of the dependent Claims.
  • the bolt-setting tool for driving bolts or the like into components comprises a bolt guide and an axially displaceable Driving pistons, between which an operable connection can be made with the driving piston, sleeve-shaped pressure piece is arranged.
  • the pressure piece protrudes into a receiving space the bolt guide protrudes and has a smaller diameter extending in the setting direction cylindrical extension on which at least one elastic buffer element is arranged, which extends between two sealing rings.
  • first sealing ring between an annular stop surface of the pressure piece and one against the End face of the buffer element facing the setting direction and radially resilient biased against the inner wall of the receiving space of the bolt guide.
  • the second sealing ring is between an annular stop surface of the bolt guide and an end face of the buffer element facing in the setting direction and arranged radially resiliently biased against the lateral surface of the cylindrical extension of the pressure piece.
  • the mutually movable parts have the Thrust piece and the receiving space of the bolt guide, a massive game.
  • sealing rings are provided on both axial sides of the buffer element, that the sealing ring in the gaps between the Thrust piece and the inner wall of the receiving space or between the cylindrical Extension of the pressure piece and the inner wall of the bolt guide is clamped.
  • the between the annular stop surface of the pressure piece and the opposite of In this case, the end ring of the buffer element facing the setting direction is arranged radially resiliently biased against the inner wall of the receiving space of the bolt guide and closes the gap between the pressure piece and the inner wall of the Recording room.
  • the second sealing ring is between the annular stop surface Bolt guide and the end face of the buffer element pointing in the setting direction and radially resilient against the lateral surface of the cylindrical extension of the Pressure piece preloaded. In this way there is also the annular gap between the lateral surface of the extension and the inner surface of the bolt guide closed.
  • the sealing system with two sealing rings is self-sealing, because the high occurring during operation Internal pressures support the radial sealing forces with which the outer surface of the first Sealing ring against the inner wall of the receiving space or the inner surface of the second sealing ring is pressed against the outer surface of the extension. Through the two Sealing rings will jam the parts which are movable relative to one another and in particular Pinching and damage to the buffer element due to the massive Prevents existing ring gaps.
  • the sealing rings are simple in their construction and make it possible to also use existing bolt-actuators of the generic type Way of retrofitting.
  • the sealing rings are advantageous as resilient multi-disc sealing rings trained with external or internal tensioning effect. This makes possible especially with retrofit kits, an adaptation to the existing design Conditions and compensation for any axial play that may exist.
  • the sealing rings must meet the internal pressures and temperatures that occur during operation withstand and the required radial external or internal clamping function exhibit.
  • the sealing rings are particularly easy and inexpensive to manufacture a spring steel.
  • the sealing rings are an advantage on the stop surfaces of the pressure piece or the bolt guide or on the end faces attached to the buffer element.
  • the buffer element is advantageously in one piece, sleeve-shaped. It has an outer diameter at least in some areas on, which is smaller than the inner diameter of the receiving space Pin guide so that it radially expands in the desired manner when compressed can to reduce the excess energy.
  • sealing rings are firmly attached to the end faces of the buffer element connected, for example glued or vulcanized.
  • the sealing rings and the buffer element form a one-piece component that is easy to store and is mountable.
