Definitions

  • ABSTRACT Hand riveting tongs for blind rivets which com movable tongs leg and a tongs housin
  • mouth piece is provided for a rivetin and serving as a rotary bearing for the movable leg.
  • a chuck mechanism for gripping said rivetorn is arranged and an intermediate lever is pivotally connected with the movable tongs, the intermediate lever engages the chuck mechanism and has an abutment for contacting the movable tongs leg.
  • the present invention relates to a hand riveting tongs for blind rivets, the one tongs leg of which, also designated as a tongs housing, carries the receiving mouth piece for the rivet thorn and serves as a rotary bearing for the other movable tongs leg, the power tongs leg, which effects the clamping device of the riveting thorn, the chuck mechanism.
  • Riveting tongs in the most different embodiments have been known, which assume an automatic fixing and ejecting of the draw shaft and warrant a full exportation of the applied energy as well as a drawing direction perpendicular to the parts to be riveted, in order to avoid a shearing of the drawing shaft.
  • the clamping-piececarrier of the chuck mechanism for the blind rivet forms the one side of a pivoted pentagon having five pivot points and forming in the starting position a parallelogram.
  • hand riveting tongs are provided, in which an intermediate lever is pivoted on the movable tongs leg, the power tongs leg, which intermediate lever engages on the one hand the chuck mechanism and on the other hand has an gages laterally .in recesses, by example, annular grooves, of the chuck mechanism,
  • the working end of the intermediate lever can be formed,however, also as a pin, preferably with aball-shaped end, which enters likewise arecess,.particularlyin a passage opening of the chuck mechanism.
  • This embodiment is to beproduced in a particularly simple manner.
  • the-movable tongs leg is formed fork-like at its forward end and grips around therebytheintermediate lever,ln order to achieve afork-likeformation of the working end of the intermediate lever, the latter can be also divided, so thatit consists of two levers, which, on the one hand, diametricallyidisposed opposite eachother enter at the working ends the recess of the chuck mechanism and are connected together, on the other hand, at the free end directly on over a cross-stay.
  • Thisembodiment is also comparatively simple concerning the manufacturing technic. If an intermediate lever is shown which consists oftwolevers, it is alsopossible, to connect the levers on the working end, so that there is formed a pin.
  • This embodiment has the advantage,
  • the intermediate lever consists of two levers, it is suitably formed fork-like for gripping around of a one-piece movable tongs leg.
  • the intermediate lever is pivotally connected, in accordance with the present invention, with the movable tongs leg by means of a bolt and is rotatably mounted preferably at its free end by means of a further bolt on the tongs housing.
  • This further bolt enters suitably into a longitudinal slot provided in the intermediate lever, so that also a certain horizontal movement of the intermediate lever is possible.
  • the free end of the intermediate lever is formed as abutment.
  • the abutment can be provided, however, also between the pivot point for the tongs leg and the free end of the intermediate lever on the latter. If the intermediate lever consists of two levers, advantagously the latter is formed as abutment in care of a direct connection at the free end or in case of a connection of both lever ends by means of a cross stay.
  • the arrangement, in accordance with the present invention, of an intermediate lever causes, in a surprising manner, with a simple structure, a reduction of the power requirement during riveting and reduces the friction, since the bearing pressures on the chuck mechanism are extensively reduced.
  • the working-physiological important clamping of the backshock upon tearing of the riveting thorn results from the fact, that the back-shock is exerted upon the lever system.
  • stronger rivets can be worked thereby. It is obvious, that the present invention makes possible a faster and more rational riveting and enlarges the range of application of the hand riveting tongs.
  • FIG. 1 is a side elevation of the hand riveting tongs, designed in accordance with the present invention, with closed tongs legs with the chuck mechanism partly in section;
  • FIG. 2 is a side elevation with opened tongs legs with the chuck mechanism likewise partly in section;
  • FIG. 3 is a longitudinal section along the lines Ill-Ill of FIG. 1;
  • FIGS. 4, 5 and 6 are longitudinal sections of further embodiments of the present invention corresponding with FIG. 3
  • the hand riveting tongs comprises a tongs leg 1 serving as tongs housing and a movable tongs leg 2. At its forward end the tongs housing terminates into an end formed like a hitting part of aharnmer.
  • This head la formed as a hammer-like projection is inclined with its vertical axis to the horizontal axis of the tongs housing 1, whereby a closer access to the riveting station is madepossible.
  • the head la is the guide for the chuck mechanism 4, formed as a bushing, whereby the chuck mechanism-receives the two-part chuck jaws 3, the pressure bushing 6 and the pressure spring 7 and is closed up by the closing screw 8.
  • the receiving mouth-piece 10 for the rivet 11 is clearly shown inFIGS. 1 and 2.-Further mouth-pieces ,10a and 10b are provided in the bushings of the tongs leg 1.
  • the intermediate lever 9, designed in accordance with the present invention is disposed between the side walls of the tongs leg 1 which is U-like forked at the forward end.
  • the forward or working end 9a of the lever is formed fork-like and enters a recess 4a of the chuck mechanism 4.
  • the rear free end of the intermediate lever 9 is formed as abutment 9b for the tongs leg 2.
  • the tongs leg 2 hits the abutment 9b upon drawing a break of the shaft of the rivet thorn and causes thereby a damping of the back-shock created thereby.
  • This damping is brought about by the arrangement on the intermediate lever, different from an arrangement, in which the abutment 9b is provided on the tongs housing. It can be increased, if the abutment is displacedtowards the pivot 12.
  • the power tongs leg 2 is rotatably mounted on the tongs housing 1 by means of a bolt 13, which passes through a slot 14 of the intermediate lever.
  • This slot 14 is a longitudinal slot curved corresponding with the rotary movement of the tongs leg 2, which longitudinal slot thus renders possible the lifting movement of the intermediate lever 9.
  • the tongs lever 2 is pivoted to the intermediate lever 9a by means of a bolt 12.
  • the lever translation obtained by the arrangement of the present invention, reduces the power requirement during riveting.
  • the intermediate lever 9 is movably mounted at its free end by means of a further bolt 15 on the tongs housing.
  • the intermediate lever 9 is equipped with a slot 16 for additional longitudinal movement.
  • the bolts 13 and 15 are disposed in one plane.
  • Grips 17 and 18, preferably of synthetic material and equipped with abutment cams, are secured to the housing tongs l and the tongs leg 2, for providing a better gripping.
  • the tongs are shown in open position, whereby the chuck mechanism is open for insertion of the rivet 11 through the mouth piece 10.
  • the bolt 13 is then at the upper end of the slot 14.
  • FIG. 3 shows a longitudinal section along the lines III- -III of FIG. 1.
  • the intermediate lever 9 is formed forklike at its working end 9a and enters an annular groove 4a of the chuck mechanism 4.
  • the movable tongs leg 2 is likewise formed fork-like at one of its ends and grips around the intermediate lever 9.
  • FIGS. 4, and 6 disclose further embodiments of the present invention in longitudinal sections similar to that shown in FIG. 3.
  • the intermediate lever 29 and 49 respectively, consists of two levers.
  • the working end 290 is formed in FIG. 4 fork-like and enters diametrically opposite an annular groove 24a of the chuck mechanism 4, while the free end of the two levers is directly connected and has the abutment 29b.
  • the working end 49a is connected pin-like and enters a passage opening 44a in the chuck mechanism.
  • the free ends of the lever 49 are connected by a crossstay 49b which is simultaneously formed as an abutment.
  • Cross-stay 49b does not extend beyond the sides of levers 49, and overlies bolt as illustrated in in FIG. 6.
  • FIGS. 5 shows in the simplest form, in the production-technical sense, of the one-piece intermediate lever 39 with the pin-shaped working end 39a which enters a passage opening of the chuck mechanism 4. while the free end 39b is formed again as abutment.
  • the end of the movable tongs leg 2 and 32, respectively is forked and grips around the intermediate lever 9 and 39, respectively, while in the embodiments of FIGS. 4 and 6 the lever 29 and 49, respectively, grips around the one-piece end of the movable tongs leg 22 and 42, respectively.
  • the end of the pin 39a and 49a, respectively can suitably be also of ball-shape in the embodiments shown in FIGS. 5 and 6.
  • the connection thereof takes place by the bolt 12, while the intermediate lever is rotatably mounted on the tongs housing 1 by means of the further bolt 15.
  • the movable tongs leg 2 is rotatably mounted on the tongs housing 1 by means of the bolt 13.
  • the shape of the intermediate lever 9 can be chosen in any manner.
  • the lengths of the intermediate lever are variable in the cooperation with the movable tongs leg 2 and the chuck mechanism, whereby the ratio of the power transmission can be influenced.
