Definitions

  • the invention relates to a driving tool for fasteners according to the preamble of claim 1.
  • Such driving tools have a muzzle tool with an ejection channel through which fasteners can be driven out.
  • the discharge channel is fed by a magazine on the side.
  • a driving plunger is displaceable transversely to the feed opening and pushes a fastening means out of the muzzle tool during an ejection movement.
  • the plunger is held on a working piston which is arranged in a working cylinder.
  • the working displacement above the working piston is at filled with compressed air during a driving process. It is ventilated to return the working piston to its original position.
  • a working cubic space below the working cylinder can be filled with return air to drive the piston back.
  • Valve arrangements are used to control the air in the upper working stroke of the piston.
  • parallel valves which are arranged parallel to the working piston and are directly assigned to a trigger switch.
  • head valve devices there is a valve arrangement directly above the working cylinder. In the open position, larger flow cross-sections between the working cubic space and compressed air reservoir are released, so that the driving-in process takes place with significantly improved efficiency.
  • Top valves have a valve piston above the cylinder, which in a lower position shuts off an inlet duct connected to the compressed air source to the upper working space of the working cylinder.
  • the valve piston sits with the underside sealingly on the upper edge of the cylinder.
  • the valve piston closes off an outlet channel which is connected to the working stroke space through a through-hole in the valve piston is.
  • the valve piston can have a hollow cylindrical piston shoulder containing the bore, which is sealingly guided in a bushing and in the upper position lies sealingly against a valve seat element.
  • the socket can also serve as a stop for the top of the valve piston around the hollow cylindrical piston neck.
  • the valve piston For the movement between the lower and the upper position, the valve piston has a lower effective area which is constantly acted upon by the compressed air source. Furthermore, it has an upper effective area which can be acted upon either by atmospheric pressure or from the compressed air source by means of a control valve.
  • the control valve can be arranged next to the valve piston and can be actuated by a trigger by means of a valve rod guided through the housing. The control valve can also be located directly next to the trigger and connected to the main valve via a longer control channel.
  • the plastic valve piston For sealing in its lower position, the plastic valve piston can be seated directly on the upper edge of the cylinder. The slightest damage to the sealing surface can result in leaks. In addition, such valve pistons work in, so that at an exchange for repair purposes can also cause leaks. As a result, the valve piston is usually provided with an elastic seal at the bottom. An elastic element is also often attached to the top of the valve piston, which is intended to dampen the system at a stop such as the bushing already mentioned.
  • valve piston With recesses at the top and bottom, in which O-sealing or damping rings are placed.
  • the punctures are usually turned in costly.
  • assembly of the hard O-rings is complex. These are nevertheless at risk of falling out of their grooves under operational stress, which can damage the device or make it unusable.
  • the object of the invention is to improve the sealing of the valve piston with respect to the working cylinder and / or its damping with respect to an upper stop in a driving tool of the type mentioned at the beginning.
  • the positive connection or clawing of the sealing ring and / or the damping ring with the valve piston improves the sealing or damping and the reliability of the device.
  • the positive connection allows a reduction in the effort for the manufacture of the valve piston and the placement of the sealing or damping ring.
  • the positive connection is ensured by connecting webs which penetrate through the axial bores of the valve piston and are connected at one end to the sealing ring and at the other end to the damping ring.
  • the ring material can form the connecting webs.
  • the sealing ring, the damping ring and the connecting webs can be placed on the valve body by spraying, thermoplastic elastomers being considered as the material.
  • Thermoplastic elastomers have the processing behavior of thermoplastics and, when cured, the elasticity of elastomers.
  • other soft or elastic materials can also be considered for the sealing and / or damping ring, for example POM.
  • the injection point for the ring material can advantageously be arranged on the side of the damping ring, so that it seals against the working cylinder not affected.
  • a linear magazine 8 for fastening means is attached to the side of the mouth tool 7 and is connected to the discharge channel 6 via a feed opening.
  • the housing 1 also has a handle 9, in which a compressed air storage space 10 is provided, which can be connected to a compressed air source via a hose connection 11. At the rear end, the handle 9 is connected to the magazine 8 via a bridge 12. There is also a locking lever 13, which is used to open and close the magazine 8 when refilling fasteners.
  • a trigger lever 14 is mounted on a control valve carrier 15 in addition to the housing head 2.
  • the control valve carrier 15 houses a switching pin 16 which contacts the release lever 14 with a cylindrical section and is aligned with a conical section concentrically with a sealing bush 17 in the housing 1 connected to the compressed air supply chamber 10. In the position shown, the switching pin 16 with its conical section releases the passage of the sealing bush 17, so that a cavity 18 formed in the control valve carrier 15 is connected to the compressed air supply space.
  • the release lever 14 is actuated by swiveling up, the cone section is moved into the opening of the bushing 17, so that the aforementioned connection is interrupted.
  • an O-ring seal (not shown) arranged in a groove between the conical section and the cylindrical section is lifted off a sealing seat of the control valve carrier 15 and in the area of the cylinder section 16 a connection of the cavity 18 with the environment is released.
  • the cavity 18 is connected to a control channel which has a tube 19 crossing the compressed air supply space 10 in a blind bore 20 made from the underside of the housing.
  • the control channel has a connection channel 21 which is connected to the blind bore 20 and which opens into a valve chamber 22 which is arranged above the working cylinder and above which a housing cap 23 is located.
  • a valve piston 24 is arranged in the valve chamber 22 and carries an O-ring 25 on the outer circumference.
  • the valve piston 24 has an outer step 26 for supporting the O-ring on the inner circumference and on the top.
  • the valve piston 24 has a hollow-cylindrical piston extension 27. It is also provided with a central through-bore 28 which extends through the piston extension 27.
  • the through hole 28 has an extension which receives a coil spring 29.
  • the helical spring 29 is supported on the underside of a valve seat element 30 which is held in a blind bore in the housing cap 23.
  • the piston shoulder 27 is guided on the outside in a bushing 31, which seals on the inside against the piston shoulder O-ring 32 carries.
  • the bushing 31 is sealed by a further O-ring 33 on the inner wall of a screw connector that holds the housing cap 23 in the housing.
  • the socket 31 is supported at the top on the bottom of the housing cap 23. There it has radial outflow grooves 34. These communicate with radial outflow grooves 35 of the housing cap 23, which are connected to the surroundings.
  • the bushing 31 is provided on the underside at 36 with radially extending ribs (not shown).
  • the valve piston 24 has axial through bores 37 which are arranged concentrically with its central axis on the outside around the piston shoulder 27.
  • the axial through holes open on the underside 38 of the valve piston 24 in a circumferential annular groove 39 with a rectangular cross section. They open at the top 40 of the valve piston 24 in a circumferential annular groove 41 with a trapezoidal cross section, which widens towards the top 40.
  • the through-holes 37 and the grooves 39, 41 are filled with an elastic sealing and damping material, which protrudes in a dome-shaped manner over the bottom 38 and the top 40 Forms sealing ring 42 and damping ring 43 with connecting webs 44 in the through holes 37.
  • the valve piston 24 is injection molded from a plastic. This can be a hard or impact-resistant material, e.g. for a POM. The piston must be made sufficiently firm to withstand the pressures that occur and to support the spring permanently.
  • the injection mold is divided at the level of the outer stage 26.
  • the sealing and damping material is sprayed onto the finished valve piston 24.
  • a thermoplastic elastomer is used.
  • the valve piston can be overmolded after insertion in another tool.
  • the injection point is preferably located on the top 40.
  • the sealing ring 42 formed in this way is assigned to the upper edge of the working cylinder 3, which forms a counter sealing surface.
  • the damping ring 43 interacts with the ribs 36 on the underside of the bush 31.
  • the working cylinder 3 is connected via radial bores 45 to approximately a third of its height with a return air chamber 46 surrounding it. This is also via radial holes 47 connected to the interior of the working cylinder at the lower end.
  • the device functions as follows: In the starting position according to FIG. 1, the compressed air supply space 10 is connected to the valve space 22 via the cavity 18, the tube 20 and the connecting channel 21. Compressed air thus acts on the upper side of the valve piston 24. At the same time, it rests on the underside of the valve piston 24 in the area which extends beyond the working cylinder 3. Since the pressure on the upper effective surface of the valve piston 24 supported by the spiral spring 29 is greater than the pressure on the lower effective surface, the valve piston with the sealing ring 42 is pressed sealingly against the upper edge of the working cylinder 3. The working stroke space above the working piston 4 is connected to the environment via the through-hole 28 of the valve piston 24 and the radial outflow grooves 34, 35 and is thereby ventilated.
  • valve piston 24 the movement of the valve piston 24 upwards allows compressed air to flow from the compressed air storage space 10 over the upper edge of the working cylinder 3 into the working stroke space, so that the working piston 4 is suddenly driven downward.
  • a fastener refilled from the magazine 8 is driven out by the tappet 5 through the muzzle tool 7.
  • a further driving-in process can then be triggered by actuating the trigger 14.
