Definitions

  • the invention relates to a rivet setting tool for setting threaded rivet nuts or blind rivet nuts with a feed device which can be actuated for the upsetting process and which gives the threaded bolt or pull bolt an axial movement and which has a cylinder-piston arrangement consisting of a pressure piston and a working piston, and with a pusher, who moves a control valve rod by exerting pressure, which opens or closes connection openings for a pressure medium for actuating the tool, the pusher being movable in a plane oblique to the axis of a control valve rod and moving it downward.
  • the pressure piston of the feed device is pneumatically actuated by a corresponding assignment of valve openings and compressed air is conveyed into the device for sucking in a blind rivet and for removing torn rivet pins.
  • the valve rod extends from the pusher arranged below the head on the device to the base of the device, in which the pneumatically actuated pressure piston sits and into which the compressed air line opens.
  • the invention is therefore based on the object of making available a rivet setting tool of the type mentioned, in which the actuation is facilitated.
  • the invention is that the valve rod in a valve piston seated in a cylinder chamber runs out and that the pusher acts on a valve tappet, which opens a pressure medium passage from a pressure chamber provided in the valve piston to the cylinder chamber.
  • An advantageous embodiment consists in that the pressure medium passage consists of an annular space which is formed in that the valve tappet has a smaller diameter than the valve tappet bore which leads to the cylinder chamber, and in that the cylinder chamber is formed between the end face of the valve piston and the cylinder end wall, through which the valve lifter is passed in a sealed manner.
  • the pressure chamber provided in the valve piston expediently consists of a compressed air bore connected to the pressure medium supply and passing through the valve rod in the center.
  • a helical spring arranged in the compressed air bore urges the valve body, which is attached to the end of the valve tappet, into the closed position.
  • valve piston be seated on the valve rod and communicate this to its movement.
  • the pusher expediently has an actuating bolt which acts on the valve tappet.
  • the actuating bolt can carry a cone at its end, which is in contact with the rounded valve stem.
  • a vent hole in the cylinder chamber is open in the rest position of the pusher.
  • the invention proposes that the valve tappet and the actuating pin release a ventilation channel from the cylinder chamber between themselves and the guide surfaces and that a seal closes the ventilation passage when the pusher is actuated.
  • An expedient measure is that the trigger cover, to which the actuating bolt is attached, has one between itself and a guide body closes the existing ventilation passage in the actuation position.
  • a rivet setting tool 1 which consists of a device part 2 and a handle part 3.
  • a working piston 4 with a working piston rod 5, which acts on the mouthpiece 6 at the front end of the device part 2 in order to carry out the operations with the rivets 7.
  • a pneumatically actuated pressure piston 8 is seated in the grip part 3 and sits in a pressure chamber 9.
  • a control valve rod 10 which is equipped at its lower end 11 with valve seats and has a valve rod channel 12 which can be aligned at its upper end with a bore 13 in the handle part.
  • a valve rod channel 12 which can be aligned at its upper end with a bore 13 in the handle part.
  • a pusher 15 is arranged obliquely to the axis of the control valve rod 10 and can be moved obliquely, ie at an angle to the axis of the control valve rod 10.
  • valve rod 10 runs out at its upper end in a valve piston 18 which is seated in a cylinder chamber 19.
  • the pusher 15 acts on a valve tappet 17 which is seated in a pressure medium passage 22.
  • This pressure medium passage 22 is formed in that the outer diameter of the valve tappet 17 has a smaller diameter than the valve tappet bore in the valve piston 18.
  • a valve body 23 is arranged, which after moving downward in FIG. 2 opens the pressure medium passage 22.
  • a connection is established between the pressure medium passage 22 and the pressure chamber 24, which communicates with the valve rod channel 12, which is filled with compressed air.
  • This passes through the pressure medium passage 22 into the cylinder chamber 19 and moves the valve piston 18 and thus the valve rod 10 downward, which in turn moves the pressure piston upward through the compressed air flowing into the pressure chamber 9 and actuates the working piston in the device part 2.
  • valve tappet If the pusher 15 is relieved, the valve tappet returns to its initial position due to a helical spring 25 located in the pressure chamber 24. As a result, the pressure medium passage 22 is closed by the valve body 23.
  • the air in the control chamber 19 passes through a passage 26 into a housing recess 27 in which the pusher 15 is seated with a guide body 28.
  • Extending through a central bore 29 in the guide body 28 is an actuating bolt 30 extending from the pusher 15, which carries at its lower end a cone 31 which is in contact with the rounded end 16 of the valve lifter 17.
  • the pusher 15 If the pusher 15 is released, ie it comes into the rest position, the pusher 15 moves an annular seal 32 arranged thereon from its seat 33 in the guide body 28, and the compressed air can escape from the housing bore 27 through the central bore 29 in the guide body 28 to the outside. This also relieves the pressure on the cylinder chamber 19, and the compression spring 14 presses the valve rod 10 with the valve piston 18 upwards again into the starting position.
