Definitions

  • the invention relates to a powder-operated setting tool according to the preamble of Claim 1.
  • a powder-operated setting tool is known, one opposite a housing axially displaceable pin guide with a perpendicular to the longitudinal extent the bolt guide guide channel, a guide element and a stop points.
  • the guide element is used to hold a Fastener magazine and the supply of the fastener magazine to the guide channel by means of spring force.
  • the clear cross section of the Guide element runs in the transition area to the bolt guide coaxial to the clear Cross-sectional area of the guide channel.
  • the one located on the bolt guide Stop protrudes into the clear cross-sectional area of the guide channel and serves the coaxial alignment of a fastener to be driven in relation to a Guide hole of the bolt guide and as a lock, so that the fastener magazine can only be moved in the direction of the pin guide to a limited extent.
  • the stop interacts with the fastener to be placed. After every Setting process takes place a further transfer of the fastener magazine in the guide channel when the driving piston accelerates back to its starting position and with its piston rod no longer in the clear cross-sectional area of the guide channel protrudes.
  • the invention has for its object to a powder-powered setting tool create, which ensures that an offset of the fastener magazine takes place only in the starting position or rest position of the driving piston.
  • the pivoting of the lever during the pressing process is expedient achieved by means of a lever with a control cam assigned to the housing cooperates.
  • the design of the control curve can be used for a given The speed at which the lever moves into the Locked position swiveled, influenced. About the distance of the control curve from the housing it is possible to start the pivoting of the lever depending to determine the pressure path.
  • a control cam that can be displaced parallel to the longitudinal extension of the bolt guide having control arranged.
  • control element is advantageously one on the bolt guide arranged pin formed in the setting direction against the force of a spring element is relocatable.
  • the control curve is, for example, a surface inclined in the longitudinal direction of the pin educated.
  • the lever in a perpendicular to the longitudinal extension of the bolt guide Level swiveling.
  • the axis of rotation of the lever runs parallel to the longitudinal extent the bolt guide.
  • the lever is preferably against the force of a spring part in the clear cross section of the guide channel pivotable. In this way, an independent pivoting takes place the lever into its release position if the setting tool after a the setting process is lifted off the ground and the Move the housing and the pin guide apart.
  • the lever can perform the function according to the invention.
  • the lever is formed with two arms, a first arm with the fastener magazine and a second arm interacts with the cam.
  • the first arm of the Lever can for example laterally against the strip-shaped carrier body of the Press fastener magazines into a side recess of the Fastener magazines protrude or between two consecutively arranged Fasteners grip the fastener magazine vertically protrude beyond its longitudinal extent.
  • the second arm works with the one that has the control curve Pin together.
  • a spring part pressing the lever into the release position acts, for example, with the first arm together when the pin is with its, from the fastener magazine Control cam facing away with the, facing the fastener magazine Side of the lever cooperates.
  • a lever in the freezing position pressing spring part interacts, for example, with the second arm when the Pen with its control element facing the fastener magazine with the cooperating side of the lever facing away from the fastener magazine.
  • the setting tool shown in FIG. 1 has a housing designated overall by 1 with an end face 2 on the setting direction, that of a bolt guide 3 in the setting direction is towered over. Contrary to the setting direction, the bolt guide 3 is over a Threaded connection 22 with an axially displaceable relative to the housing 1 Guide cylinder 23 connected.
  • the guide cylinder 23 is used for recording and Guide a driving piston, not shown.
  • This driving piston is composed of a piston part and one projecting from the piston part on the setting direction Piston rod.
  • the guide cylinder 23 has a cartridge bearing, not shown, which the inclusion of a powdered propellant charge arranged in a cartridge 24 serves.
  • Several cartridges 24 are in a row on a strip-shaped Cartridge magazine 25 arranged, which partially protrudes from the housing 1.
  • the setting tool around the pressure path S against a not shown Be pressed underground, so that the actuation of an ignition mechanism, not shown is possible.
  • the housing 1 moves relative to the the base-supporting bolt guide 3 and the guide cylinder 23.
  • the pin guide 3 protrudes essentially to the side sleeve-shaped guide element 17, which in the connection region 30 with the bolt guide 3 is connected.
  • the guide element 17 serves to receive a strip-shaped fastener magazine 6.
  • the guide element 17 is with a pressure plate 28 and a pressure spring 29 acting on the pressure plate 28, around a fastener magazine arranged in the guide element 17 6 automatically move towards the bolt guide 3 after each setting process can.
  • the bolt guide 3 has a perpendicular to its longitudinal extent Guide channel 4, which has a central guide bore 5 of the pin guide 3rd enforced.
  • the clear cross-section of the guide element 17 and the clear cross-sectional area of the guide channel 4 run in the transition area between the bolt guide 3 and the guide element 17 coaxially with each other.
  • the strip-shaped fastener magazine arranged within the guide element 17 6 has annular receiving areas arranged one behind the other 18, in which individual fastening elements in the form of bolts 19 are arranged. These bolts 19 are axially fixed to guide disks 20, on their diameter the annular receiving areas 18 are substantially matched. The Bolts 19 protrude beyond the strip-shaped carrier body 21 of the fastener magazine 6 in the height parallel to the longitudinal extent of the pin guide 3 on both sides.
  • a pivotable lever 8 is also on the bolt guide 3 a locking function arranged.
  • the lever 8 is in a perpendicular to the longitudinal extent the bolt guide 3 plane extending around a parallel to the longitudinal axis of the bolt guide 3 extending axis of rotation 12 pivotable and two arms, one first arm 9 has a locking claw 11, which in the locked position of the lever 8 in a lateral recess 31 on the strip-shaped carrier body 21 of the fastener magazine 6 protrudes.
  • the second arm 10 of the lever 8 acts with a control curve 13 of a control element 14 in the form of a pin together in the setting direction against the force of a spring element 15 in a receiving bore 32 of the bolt guide 3 can be moved.
  • the pin has the control cam at the end area on the setting direction side 13 in the form of an inclined surface pointing in the setting direction. That the inclined surface opposite end of the pin is with a radial extension provided, as an abutment for the supported on the pin guide 3, the pin surrounding spring element 15 is used.
  • the inclined surface of the pen is from Fastener magazine 6 facing away and acts during the pressing process with the the fastener magazine 6 side of the lever 8 together.
  • a spring part 16 pressing the lever 8 into the release position is between the lever 8 and the bolt guide 3 and between the locking claw 11 and the axis of rotation 12 arranged.
  • FIGS. 2 and 3 The situation shown in FIGS. 2 and 3 prevails after a setting process has taken place.
  • the driving piston not shown, is in its initial position and that Fastener magazine 6 was from the compression spring 29 in the direction of the bolt guide 3 moved until the guide plate 20 of the further bolt 19 on the Stop 7 came to the plant.
  • the bolt 19 is opposite the central guide bore 5 coaxially aligned.
  • the pivotable lever 8 is in the release position and the control element 14 in the form of a pin does not work with the lever 8 together.
  • the situation shown in FIG. 4 prevails before the setting process Position of the setting tool.
  • the bolt 19 to be placed is still in the strip-shaped carrier body 21 of the fastener magazine 6.
  • the control element 14 presses laterally against the lever 8 so that it is in the locked position located.
  • the locking claw 11 of the lever 8 projects into a lateral recess 31 of the strip-shaped carrier body 21.
