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 ejected.
  • 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 stroke space above the working piston is filled with compressed air during a driving process. It is released 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.
  • so-called "parallel valves” are known, which are arranged parallel to the working piston and are directly assigned to a trigger switch. This valve arrangement is connected to the working cubic space via narrow channels, so that the efficiency is relatively low.
  • the housing can have a screw cap which seals the working stroke space. The air displaced during the return movement of the working piston is discharged through an exhaust in the area of the device handle, where it does not bother a user.
  • head valves are provided, in which a valve arrangement is located 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.
  • a main valve is conventionally provided above the cylinder.
  • This has a valve piston in a valve chamber, which, in a lower position, shuts off an inlet channel connected to the compressed air source to the upper working stroke space of the working cylinder.
  • the valve piston closes off an outlet channel which is connected to the working stroke space through a bore in the valve piston.
  • the valve piston has a lower effective area which is constantly acted upon by the pressure of the compressed air source.
  • it has an upper effective area which can be acted upon with the aid of a control valve either with atmospheric pressure or the pressure of the compressed air source.
  • the control valve is usually arranged next to the valve piston and can be actuated by the trigger by means of a valve rod guided through the housing.
  • the control valve is located directly next to the trigger and is connected to the main valve via a longer control channel.
  • the housing cap is arranged above the main valve. It is screwed to the device housing and sealed against it.
  • a valve seat element is arranged in the housing cap, which closes the through bore of the valve piston in its upper position and shuts off the outlet channel. Then compressed air can get through the inlet duct into the working stroke space and drive the working cylinder downwards.
  • the outlet channel leads from the valve seat element to an outlet opening on the outside of the housing cap.
  • the compressed air source is separated from the working stroke space and the air displaced by the working piston which is moved back is released into the open through the outlet duct.
  • the exhaust air flowing out of the housing cap can disturb a user, and the outflow can be directed directly at his face in certain working positions. For this reason, housing caps with air guiding devices attached to them from outside have already become known, which are said to have a favorable influence on the outflow.
  • the known head valve devices are complex due to the cap design made of cast metal or plastic, their sealing to the housing and any guide devices for exhaust air.
  • the object of the invention is to create a driving tool for fastening means of the type mentioned at the outset, which enables inexpensive discharge of the exhaust air with less effort.
  • the outlet channel has at least one channel opening on the circumference of the housing cap.
  • a rotatable diaphragm ring with at least one outlet opening is assigned to the channel opening on the outside of the housing cap.
  • a channel opening and outlet opening connecting connecting channel extends in the circumferential direction.
  • the aperture ring is sealingly clamped between the housing cap and the housing.
  • the outlet opening can be adjusted in different directions by turning the aperture ring. The user can therefore adjust the outlet opening in any application so that the outgoing exhaust air does not bother him.
  • the bezel ring also seals the housing cap and housing. In contrast to the prior art, no sealing element separate from the air guiding device is required.
  • the clamp seat of the aperture ring ensures that it is fixed to the device without additional fastening elements being required.
  • the outlet channel is preferably guided through at least one radial outflow bore of the housing cap with the channel opening at the outer end.
  • the connecting channel can have a groove on the circumference of the housing cap. Several channel openings can open in the groove.
  • the outlet opening can be slit-shaped and extend over a peripheral section of the diaphragm ring.
  • an air guide surface of the diaphragm ring can be assigned to it, which preferably directs the exhaust air away from the upper side of the device, which frequently faces the user.
  • the diaphragm ring preferably has an L-shaped cross section, its vertical leg surrounding the circumference of the housing cap covered and its horizontal leg is arranged between the front sealing surfaces of the screw cap and the housing. Clamping the horizontal leg ensures the seal between the housing cap and the housing. Clamping forces that still allow the aperture ring to twist can suffice.
  • the housing cap can be designed as a flange cap which is connected to the housing by means of several screws. Then the aperture ring can be outside the screw circle. However, the housing cap is preferably connected to the device housing via a central threaded screw connection. This facilitates tilt-free assembly, service and the setting of the clamping force for the aperture ring. In addition, the housing cap can be made solid, so that it can be used like a hammer head for reworking. This device function is favored by the design of the air guiding device. The cap no longer needs to be elaborately designed as a metal or plastic casting, but can be an inexpensive turned steel part.
  • the threaded screw connection preferably has an external thread on a hollow cylindrical cap shoulder of the housing cap and an internal thread on the upper edge of the valve space.
  • a control channel of the control valve can open below the housing cap in the valve chamber.
  • the control channel preferably has a connection section to the valve chamber which is accessible from the outside in a linear movement when the housing cap is removed. It is also preferred that the control valve or the control channel have a blind hole which is introduced from the underside of the housing.
  • the valve piston can seal in a hole in the device housing, so that a shoulder on the valve piston for an O-valve sealing ring can be dispensed with.
  • the shoulder is formed in the device housing.
  • the main valve body can be manufactured with a simple tool. There is no burr in the groove for the sealing ring.
  • a further opening on the upper side of the housing is avoided, so that a closure by the screwable housing cap is sufficient.
  • the valve piston of the main valve preferably has a piston extension which is sealingly guided through a bushing of the housing cap and, in the upper position, lies sealingly on the valve seat element.
  • the socket can be held on the outside in a sealing manner in the housing cap.
  • the bushing can have a hollow cylindrical bushing attachment which has radial duct sections of the outlet duct.
  • the valve seat element can be arranged in a blind bore in the housing cap. Then the housing cap with bushing or valve seat element can be unscrewed from the housing, the valve piston remaining in the valve chamber.
  • a housing 1 which has a working cylinder 3 in a housing head 2, in which a working piston 4 is arranged.
  • the working piston 4 is connected to a driving plunger 5 which is guided into an ejection channel 6 of a muzzle tool 7.
  • 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 connected to the compressed air supply chamber 10 in the housing 1. 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 trigger lever 14 is actuated by swiveling up, the cone section is pushed into the opening of the bushing 17, so that the above connection is interrupted.
  • an O-ring seal (not shown) arranged in a groove between the cone section and the cylinder section is lifted off a sealing seat of the control valve carrier 15 and a connection of the cavity 18 with the surroundings is released in the area of the cylinder section 16.
  • 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 connecting 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 3 and is closed at the top by a housing cap 24.
  • a valve piston 25 is arranged in the valve chamber 22 and carries an O-ring 26 on the outer circumference. As can be seen more clearly in FIG. 3, the valve piston 25 has an outer step 27 for receiving the O-sealing ring 26.
  • the valve piston 25 has a hollow cylindrical top Piston lug 28.
  • the valve piston has a central bore 29 which extends through the piston lug 28. At the top, the through bore 29 has an extension 30 which receives a helical spring 31.
  • the valve piston 25 has an O-ring groove 32 at the bottom, in which an O-ring 33 sits, which protrudes somewhat on the underside of the valve piston.
  • valve piston 25 In the position according to FIG. 1, the valve piston 25 is supported with the underside of the O-sealing ring 33 in a sealing manner on the upper edge of the working cylinder 3.
  • the spiral spring 31 is supported on the underside of a valve seat element 34 which is inserted into a blind bore 35 in the housing cap 24.
  • the piston shoulder 28 is guided in a bush 36, which carries an O-ring 37 for sealing against the piston shoulder.
  • the bushing 36 has an annular groove 38 on the inside for the O-sealing ring. On the outside it has an annular groove 39 for a further O-ring 40 for external sealing.
  • the bushing 36 has radially extending grooves 41 on the underside. On the upper side, the bushing 36 carries a hollow cylindrical bushing shoulder 42, which is provided at the top with radially extending outflow grooves 43.
  • the socket 36 is supported with its upper edge on the underside of the housing cap 24, the outflow grooves 43 allowing air to pass between the inside and the outside of the socket.
  • the bushing 36 is supported on the outside via the O-ring 40 on a hollow cylindrical cap shoulder 44 of the housing cap 24.
  • the cap extension 44 has an external thread 45.
  • the housing cap 24 is designed as a flat truncated cone 45'. Between the truncated cone 45 'and the cap shoulder 44 is a short cylinder section 46 which has an annular groove 47 on the outside. Radial outflow bores 48 are arranged in the cylinder section 46, which are open toward the inside of the cap and have 47 channel openings 49 in the annular groove 47.
  • the housing cap 24 is a solid turned part made of metal.
  • the housing cap 24 is screwed into the housing head 2 with its hollow cylindrical projection 44.
  • this has an internal thread 50 at the upper edge of the valve chamber 22, which cooperates with the external thread 45.
  • the housing cap 24 carries an aperture ring 51 on the outside of the cylinder section 46.
  • the aperture ring 51 has a leg 52 for covering the annular groove 47 and a leg 53 which engages under the cylinder portion 46.
  • the leg 53 is clamped between the housing cap 24 and the upper edge of the housing head 2 and seals the housing cap 24 from the housing 1.
  • the leg 52 has a slot-shaped outlet opening 54 which extends over a portion of its circumference (approximately over 45 °).
  • the leg 51 has an air guide surface 55 which is inclined at an acute angle to the leg 52.
  • the aperture ring 51 can be rotated, the air guide surface 55 can be used as a finger attack. The position of the outlet opening 54 relative to the annular groove 47 can thus be changed.
  • radial bores 56 of the working cylinder 3 have to be mentioned, which correspond to the working volume connect the return air chamber 57 surrounding the working cylinder.
  • the return air chamber 57 is connected in the vicinity of the mouth tool 7 via further radial bores 58 with a larger cross section than the radial bores 56 with the working stroke space.
  • 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 from the compressed air supply chamber 10 thus acts on the upper side of the valve piston 25. At the same time, it rests on the underside of the valve piston 25 in the area that extends beyond the working cylinder 3. Since the pressure on the upper effective surface of the valve piston 25 supported by the spiral spring 31 is greater than the pressure on the lower effective surface, the valve piston 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 interior of the bushing 36 through the bore 29 of the valve piston 25 and to the interior of the extension 44 via the outflow grooves 43. It is also connected to the surroundings via the outflow bores 48 and the annular groove 47 of the housing cap 24 and the outlet opening 54 of the aperture ring 51.
  • the housing cap 24 can simply be screwed in and out, the valve seat element 34 and the sealingly clamped bush 36 being taken along.
  • the massive turned part can be used as a face for reworking.
  • the diaphragm ring 51 enables the exhaust air to be discharged when the piston moves upward in a direction which is favorable for the user.
  • the aperture ring 51 also seals the housing cap 24 with respect to the housing 1.
  • a housing cap 59 can have through holes 60 arranged on a circle for receiving screws, with which it can be fixed to a housing in a flange-like manner above a main valve.
  • the housing cap 59 has a laterally projecting nose 61, which serves to seal a bore of the control valve or the control channel which opens next to the main valve chamber.
  • the housing cap 59 has a central blind hole 62 for a valve seat element and a groove 63 surrounding the latter, which serves to accommodate a silencer and to discharge the exhaust air.
  • Radial outflow bores 64 are guided from the groove 63 to the circumference of the housing cap 59, where they open into an annular groove 65.
  • an aperture ring 66 On the circumference of the housing cap 59 there is an aperture ring 66 with an essentially L-shaped cross section. Its vertical leg 67 is notched at 68, so that the aperture ring on the cylindrical circumference of the housing cap 59 is adjustable over an angle until it strikes the nose 61.
  • the aperture ring 66 also has a slot-shaped outlet opening 69 which extends over part of its circumference. Above the outlet opening 69 there is an air guide surface 70 which is inclined downwards.
  • the horizontal leg 71 of the aperture ring 66 engages under the lower end face of the housing cap 59, so that it can be clamped between the latter and the upper edge of a device housing.
  • the horizontal leg 71 extends outside the through holes 60, so that these do not hinder the turning of the diaphragm ring 66.
  • the annular groove 65 extends to the circumference of the housing cap 59 only in the rotating region of the vertical leg 67 of the diaphragm ring 66. Exhaust air coming from the groove 63 through the outflow bores 64 into the annular groove 65 can therefore only flow out through the outlet opening 69 and is therefore derived depending on the rotational position of the diaphragm ring 66.
