Definitions

  • the invention relates to a rivet setting tool for setting threaded rivet nuts or blind rivet nuts according to the preamble of claim 1.
  • a tenant for blind riveting is known from DE-A-2 154 788, in which a pressure piston and a working piston are arranged.
  • the compressed air required for the setting process is led from the lower part of the device to the device head via a pressure medium channel located outside the rivet.
  • the return of the pistons takes place in the known rivet in that a compression spring urges the working piston in the direction of the device head.
  • a disadvantage is that only a flexible channel, for example a hose, can be used as the pressure medium channel, since the pressure medium channel is firmly connected to the movable guide channel via a connecting piece, so that the hose slips as a result of a constant back and forth movement of the hose or can tear off.
  • Another disadvantage is the necessary spring.
  • the invention is therefore based on the object of making available a rivet setting tool of the type mentioned at the outset which can be produced inexpensively with little assembly effort, works with great reliability and has a high working speed.
  • a rivet setting tool which consists of a device part 100 to which a handle part 200 is molded.
  • the device part 100 has a mouthpiece 1 at its front end.
  • Clamping jaws 2 are arranged behind the mouthpiece 1 and are surrounded by a conical clamping sleeve 3.
  • a guide sleeve 4 is surrounded by a compression spring 5.
  • An intermediate piece 6 is fixed with the help of a lock nut 7.
  • the entire front section of the device part 100 is surrounded by a front sleeve 8, which is fixed in the housing 101.
  • a hydraulic piston 14 is seated in the rear part of the housing 101.
  • the hydraulic piston 14 is delimited on its rear side by a rear chamber 102, which is connected via a housing recess 103 to a device sub-channel 104 running in the device part 100.
  • the handle part 200 carries a pusher 22 which is movably attached to the handle part 200 by means of a cylindrical pin 21.
  • a lever 24 is articulated to the pusher 22 by means of a cylinder pin 23 at one end and by means of a cylinder pin 25 at its other end to a valve pin 26 which is seated on a valve rod 27.
  • the valve rod 27 is provided with a valve rod channel 201 which is provided as a central bore and which is laterally at its upper end opens outwards at 202.
  • the compressed air enters an air chamber 207 and from there into the valve rod channel 201 via an air inlet channel, which cannot be seen in the sectional view, and exits at 202.
  • the outlet 202 of the valve rod channel 201 is aligned with the transverse channel 206 of the handle part channel 205, so that the compressed air can reach the rear chamber 102 on the hydraulic or working piston 14 via the handle part channel 206 and the device part channel 104.
  • the working piston is moved to the left in FIG. 1.
  • the air flows from the device channel 104 in FIG.
  • the air flowing through the valve rod channel 201 also passes through a lower transverse channel 209 into the rear pressure chamber 210 of the pressure piston 211 and presses it downward, as seen in FIG. 1.
  • the front pressure piston chamber 212 is relieved of pressure by a ventilation channel 213.
  • the same rivet setting tool can be seen in FIG. 2, the same reference symbols referring to the same parts. However, the rivet setting tool is in a second position, in which the pusher 22 is actuated, so that the valve rod 27 is moved downward against a compression spring 38 via the lever 24.
  • the sealing ring 58 located at the lower end of the valve rod 27 is moved away from its abutment on the housing cover 59, so that the compressed air flows from the inlet chamber 207 into the front chamber 212 of the pressure piston 211, as a result of which a hydraulic medium flows through the pressure channel 120 to the working piston 14 moved to the right in the position shown in Fig. 2, whereby the riveting process is effected.
  • the pusher 22 is relieved.
  • the valve rod 27 is moved up again by the compression spring 38, as a result of which the working piston 14 and the pressure piston 211 return to their position shown in FIG. 1 by closing the vent hole 217 and the vent hole 213 be opened.
  • a check valve 43 is shown on an enlarged scale. If the rivet setting tool is placed on the housing underside 60, the plunger 61 protruding from the housing 60 is moved inwards and the ball located in the seat 62 is pressed against the opening 63 so that it closes it and the compressed air no longer enters the device can penetrate. In this way, not only is unnecessary waste of compressed air prevented, but also a constant outflow of the compressed air, as in the position according to FIG. 1 past the adjustment valve 110 into the suction chamber 106. However, it would be disadvantageous to constantly change a desired pressure setting with the help of the air adjusting screw 20, and it would also be far too complex to constantly close the rotary valve 110 via the compressed air control screw 20. In this way, the compressed air in the device is switched off practically automatically via the plunger 61.

Abstract

Un outil à river des écrous filetés ou borgnes comprend un agencement d'avancement actionnable pour procéder au refoulement et imprimant un mouvement axial au boulon fileté ou au boulon tirant. Cet agencement d'avancement comprend un agencement à cylindre et à piston qui se compose d'un piston de compression et d'un piston moteur. Le rappel des pistons moteur et de compression (14, 211) se fait en déviant le milieu sous pression par la partie postérieure (102, 210) des pistons, ce qui rend superflus des ressorts de rappel. Un canal de milieu sous pression (201, 205, 104) s'étend du point d'admission (207) du milieu sous pression jusqu'à une chambre postérieure (102) en traversant la partie de manche (200). La chambre postérieure (102) est obturée d'un côté de la partie postérieure du piston moteur (14).

Claims (8)

  1. Outil de pose d'écrous de rivets taraudés ou de rivets borgnes, comprenant un dispositif d'avance qui est manoeuvrable pour le processus d'écrasement et confère un mouvement axial à la tige filetée ou à la tige de traction et qui comprend un ensemble à cylindres et pistons se composant d'un piston de refoulement et d'un piston de travail, ledit outil comprenant une chambre (207) d'admission de fluide sous pression disposée dans la partie inférieure de l'appareil, ainsi qu'un canal de fluide sous pression (201, 205, 104) destiné à diriger un fluide sous pression de la chambre d'admission (207) dans une partie supérieure de l'appareil, caractérisé en ce que le canal de fluide sous pression (201, 205, 104) passe par la poignée (200) pour aller de la chambre d'admission (207) vers une chambre arrière (102) dont un côté est fermé par le côté arrière du piston de travail (14), en ce qu'une première partie (201) du canal de fluide sous pression passe par la tige (27) de soupape et, à la première position, communique avec une seconde partie (205) du canal de fluide sous pression qui se trouve dans la poignée (200) et en ce que, lorsque la tige (27) de soupape est à une première position (Figure 1), le canal de fluide sous pression (104, 201, 205) débouche par des trous (209) dans la chambre arrière (210) du piston de refoulement qui est fermée d'un côté par le côté arrière du piston de refoulement (211), de sorte que le rappel des pistons de refoulement et de travail se produit par déviation du fluide sous pression contre les côtés arrière des pistons de manière à éviter des ressorts de rappel.

  4. Outil selon la revendication 3, caractérisé en ce que la soupape (110) est conformée en tiroir tournant qui permet une commande en continu de la force de transport des tiges de rivet arrachées.
  5. Outil selon la revendication 4, caractérisé en ce que le tiroir tournant est équipé pour le réglage d'un écrou à chapeau (20) entourant la tête (8) de l'appareil.
  6. Outil selon la revendication 4, caractérisé en ce que le tiroir tournant (110) supporte une vis (20) de réglage de la circulation d'air.
  7. Outil selon l'une des revendications 1 à 6, caractérisé en ce qu'un clapet d'arrêt (61, 62, 63) coupe automatiquement l'arrivée d'air comprimé lorsque l'outil est mis en position d'interruption de fonctionnement.
