Definitions
- the invention relates to a powder-operated setting tool with the features of the preamble of claim 1.
- DE-A-43 13 504 describes another powder-operated setting tool with a housing part, a piston guide displaceable relative to a receptacle of the housing part a guide hole for a driving piston and one with a cartridge holder related channel known.
- This channel is from the piston guide and the receptacle of the housing part surrounding the piston guide at a radial distance educated.
- the channel with the guide bore is located through an opening in the piston guide in connection.
- Located in the cartridge receiving area of the channel itself a valve device which is responsible for the formation of the areas of the setting direction Channel and the guide hole comprehensive, closed to the atmosphere Storage space serves.
- the valve device is expanded by a diameter the piston guide and a narrowing of the cross-section of the receptacle of the housing part formed within the channel. In the case of a relative shift of the The channel is closed off from the piston guide opposite the receptacle of the housing part or opened.
- the piston guide is displaced relative to one another the inclusion of the housing part in the setting direction.
- the volume of the channel or Storage space is increased, so that the pressure of the compressed propellant gases decreased.
- the propellant piston can only returned to its original position at a slow speed become. Especially with a fast setting sequence of fasteners there may be a risk that the subsequent setting process will be initiated before the driving piston has reached its starting position.
- the invention has for its object to a powder-operated setting tool of the generic type create a structure that is simple and insensitive to interference and one that is exploited the propellant gas return piston has a safe and fast Returning the driving piston to its starting position even with a fast one Seating sequence guaranteed.
- the use of a check valve that closes due to the propellant gases in the storage space enables the creation of a channel or a storage space with constant volume.
- the propellant gas pressure building up in the storage space remains constant when closing the channel.
- the driving piston accelerates in the setting direction the drive piston clears the passage.
- the remaining propellant gases which are located in the cartridge receptacle side, can pass through Area of the guide hole and / or the housing part to which Atmosphere.
- the check valve is preferably one of those flowing out of the cartridge receptacle Propellant gases can be placed in an open position against the force of a spring. If the propellant gas pressure of the propellant gases flowing out of the cartridge holder is less than the pressure of the propellant gases and the force in the storage space the spring, the channel is closed quickly with the aid of the spring.
- a spring acts on a piston which is driven by those propellant gases Cartridge take out, can be moved into an opening position.
- a powder-operated setting tool according to the invention is shown schematically shown, which is a housing 1, an axially displaceable relative to the housing 1 Housing part 7 with a receptacle 33, a handle 2, an actuation switch 3, an element guide 4 in the area on the setting direction and a check valve 5 having.
- a propellant charge magazine 6 protrudes from the housing 1.
- the element guide 4 serves to receive and guide fasteners, not shown and during a setting process.
- housing 1 shows an enlarged section of a pressed-on, powder-powered machine Setting tool before a setting process.
- housing 1 In the housing 1 is an axially displaceable Housing part 7 arranged with a receptacle 33.
- a piston guide 13 with a guide bore 8 is located in the receptacle 33 for a propellant piston 9, which uses propellant gases from a propellant charge 12 from a rear Starting position in a setting direction-side front end position is displaceable.
- the Piston guide 13 is axially fixed in the receptacle 33.
- the receptacle 33 has a passage opening 14 and the piston guide 13 are provided with a passage 20.
- the passage opening 14 and the passage 20 are arranged essentially coaxially and extend in the essentially radially to the longitudinal extension of the piston guide 13 or the housing part 7.
- the guide bore 8 and the cartridge receptacle-side interior of the Housing part 7 are connected to the atmosphere in this way.
- the opposite end of the free end of the housing part 7 is with a Cartridge receptacle 10 provided with the receptacle 33 of the Housing part 7 is connected.
- the cartridge receptacle 10 overlaps in the illustrated pressed position, a propellant charge 12 located in a cartridge.
- the cartridge is arranged on a strip-shaped propellant charge magazine 6, which in a guide channel 23 of the housing 1 substantially perpendicular to the longitudinal extent of the housing part 7 is displaceable.
- the axial displacement of the housing part 7 relative to the housing 1 corresponds at least to that in the longitudinal direction of the housing part 7 measured height of the cartridge.
- an opening 17 which is arranged in the area of the piston guide 13 on the setting direction is one of the piston guide 13 and the receptacle 33 of the housing part 7th formed channel 18a, 18b with the guide bore 8 in connection.
- the piston guide 13 is supported radially via two guide areas 21, 22 on an inner wall of the receptacle 33 from. Between the guide areas 21, 22 and in the cartridge receiving side End region, the piston guide 13 has a smaller wall thickness, so that two circumferential ones forming the channel 18a, 18b on the outside of the piston guide 13 Free spaces result which are separated from one another by the guide region 22 are.
- Both channels 18a, 18b point radially to the longitudinal extension of the piston guide 13 and in substantially parallel through holes 24a, 24b, which in a check valve arranged on the outside of the receptacle 33 of the housing part 7 5 lead.
- a flow channel 27 arranged in the check valve 5 is essentially U-shaped and connects both channels 18a, 18b to one another. Within the check valve 5, the flow channel 27 has the Channel 18a side facing a larger cross section than that of the channel 18b facing side. In this way, a shoulder 30 is formed with a sealing cone 29 of a piston 25 cooperates.
- the piston 25 is substantially perpendicular to the longitudinal axis of the through bores 24a, 24b and can be moved by a spring 26 against the shoulder 30 in pressed a closed position.
- a receiving bore 31 of the check valve 5 receives a shaft 28 of the piston 25 and guides it axially displaceable.
- Damping element 16 is arranged, the task of which is the speed of the driving piston 9 dampen if this is accelerated with over-energy.
- a guide opening 32 of the damping element 16 is cylindrical to the diameter Shaft 19 of the driving piston 9 matched.
