Definitions

  • the invention relates to a rivet setting tool for setting blind rivets with a delivery channel extending backwards from the mouthpiece through the device head for removing the torn rivet pins, with an axial feed device which can be actuated for the upsetting process and which comprises a cylinder-piston cylinder consisting of a pneumatic piston and a hydraulic piston.
  • Arrangement comprises, with a compressed air supply device for actuating the feed device and for removing the torn pins, and with an actuator movable in two operating positions, the first operating position opening the feed channel valve, which introduces compressed air for sucking the rivet into the feed channel, and the second operating position Pneumatic piston valve for actuating the feed device opens.
  • the rivet With such rivet setting tools, several operations are required. First, the rivet must be sucked in by the device, then the feed device must be actuated to carry out the actual riveting process, and then the torn pin must be conveyed out of the device into a pin collecting container. For this purpose, different actuators often have to be operated in known devices.
  • a rivet setting tool for setting blind rivets which has an operating switch which can be moved in two operating positions.
  • the control switch serves to control the compressed air within the device in such a way that in a first operating position the compressed air flowing out of a compressed air chamber arrives in a delivery channel, whereby a feed device is moved in the direction of the head of the rivet setting tool and at the same time a suction effect occurs in the delivery channel. whereby blind rivets can be sucked in by the device.
  • the invention is based on the object of making available a rivet setting tool that manages for all operations with a single actuator and in which unnecessary compressed air consumption and the noise caused thereby are avoided.
  • the invention consists in that in a rivet setting tool of the type mentioned in the rest position of the actuating member, a compressed air supply channel between a compressed air chamber and a delivery channel is interrupted by means of a delivery channel valve
  • the actuating member acts on a valve piston, to which a valve tappet is attached, which moves a valve ball out of its valve ball seat.
  • valve tappet advantageously has a smaller diameter than the valve tappet bore in which it is located, a compressed air passage leading from the valve tappet bore to the delivery channel.
  • a compression spring urges the valve ball into its ball valve seat and that the compression spring is mounted in a central valve slide bore of a valve slide.
  • valve piston comes into contact with the valve slide in the first operating position, while in the second operating position the valve piston moves the valve slide downward, thereby opening a pneumatic piston valve through which compressed air enters the pneumatic cylinder chamber on the pneumatic piston.
  • valve spool is seated in a compressed air supply bore, the inner diameter of which is larger than the outer diameter of the valve spool and that an O-ring seal in the second operating position of the actuator releases a pneumatic cylinder chamber feed bore.
  • the central valve slide bore in the region of the valve chamber is expediently connected to it by a transverse bore.
  • the actuator consists of a pusher that is movable against a compression spring within a guide is.
  • the handle is equipped with a roller that comes into contact with the top of the valve piston.
  • a blind rivet (not shown) is inserted into the mouthpiece 1 of the tool.
  • a front sleeve 2 surrounds the clamping jaws 3 and is sealed with an O-ring seal 4 against a clamping sleeve 5.
  • Inside is a guide sleeve 6 with the compression spring 7.
  • the rear part 8 of the front sleeve 2 is screwed into the housing 17.
  • a hydraulic piston 9 which is sealed against the housing 17 via O-ring seals 10 and 11.
  • a strong compression spring 12 urges the hydraulic piston 9 into its front position, shown in the figure.
  • the housing is closed at the rear by an end piece 13.
  • a conveying channel 40 leads from the mouthpiece 1 to the rear and opens into a pen collecting container 16. This is sealed to the front by O-ring seals 14 and 15 and has two vent holes 53.
  • the lower part of the housing 17 is closed by a pneumatic piston housing 20, in which a pneumatic piston 19 is seated and is sealed off from the housing parts with the aid of O-ring seals 18 and 21.
  • a pneumatic piston extension 22 projects into a housing chamber 23 which tapers in the housing 17 and is connected to the hydraulic piston 9.
  • An actuator in the form of a pusher 37 sits in a guide 38 and is movable against a compression spring 39 in the housing 37 in two operating positions.
  • the pusher 37 is equipped with a pusher roller 52 which comes to rest on the top of a valve piston 36.
  • the piston 36 has one Valve tappet 41, which extends to a valve ball 34, which belongs to a delivery channel valve 42.
  • the valve ball 34 is seated in a valve ball seat 44, which is formed in a valve slide 32 and closes off the valve tappet bore 45, which has a larger inner diameter than the outer diameter of the valve tappet 41.
  • a compressed air passage 48 extends from the valve tappet bore 45 and passes through a supply bore 53 the delivery channel 40 is connected.
  • the valve slide 32 is sealed by O-rings 35 with respect to the bore in the housing 17.
  • the valve spool 32 has a central valve spool bore 50, in which a compression spring 33 is arranged, which urges the valve ball 34 into its valve seat 44.
  • a pneumatic piston valve 43 At the lower end of the valve slide 32, which is extended by a valve rod 29, there is a pneumatic piston valve 43.
  • a compressed air supply is connected to a compressed air chamber 46 into which the lower end of the valve rod 29 projects.
  • the compressed air chamber 46 is connected to the pneumatic cylinder chamber 47 via a pneumatic cylinder chamber feed bore 49.
  • O-ring seals on the valve rod 29 are arranged so that in the second operating position they establish a connection between the compressed air supply into the compressed air chamber 46 through the pneumatic cylinder chamber supply bore 49 with the pneumatic cylinder chamber 47.
  • a compression spring 28 is arranged in the compressed air chamber 46 and urges the valve rod 29 and thus the valve slide 32 upwards.
  • the compressed air chamber 46 and the valve rod are sealed off from the pneumatic piston 19 via a retaining ring 25 and O
  • valve ball 34 in the valve seat 44 regulates the passage of compressed air through the compressed air supply bore 48, and no air flows out of the device.
  • the device is operated by pushing the button 37 into the first operating position is pressed, the roller 52 presses the valve piston 36 downward, and the valve tappet 41 moves the valve ball 34 out of the valve seat 44.
  • compressed air passes from the valve slide bore 50 into the valve tappet bore 45 and from there via the compressed air supply bore 48 into the delivery channel 40, so that a blind rivet, not shown, is sucked into the mouthpiece 1.
  • the valve piston 36 on the roller 52 moves further downward.
  • the valve slide 32 comes into contact with the valve slide 32 and thus moves it and thus also the valve rod 29 downward.
  • a connection is established between the compressed air supply or the pressure chamber 46 filled with compressed air via the pneumatic cylinder feed bore 49 to the pneumatic cylinder chamber 47.
  • the pneumatic piston is moved upwards in the device, thereby causing the hydraulic piston to move backwards against the compression spring 12 in the device, as a result of which the riveting process is carried out.
  • the pusher 37 is relieved and returns to the first operating position.
  • valve ball 34 still releases the valve seat 44, so that compressed air is fed further into the delivery channel 40 and the torn-off pin can be conveyed into the pin collecting container 16. If the pusher 37 is completely relieved, the valve ball 34 also returns to the valve seat 44, and the compressed air supply is thus completed.
  • the invention has thus made available a blind rivet setting tool in which constant air consumption is avoided and the compressed air supply in the device is closed during breaks in operation, without a separate closing valve having to be actuated. So the device comes with a single push button. This considerably simplifies operation, and compressed air consumption and the associated exit noises are avoided during short pauses in operation.
