Definitions

  • Special objects of the invention Iare to provide a machine which will form wire in a progressive manner into more or less unusual or complicated shapes and accomplish this in a continuous uninterrupted ow of operational steps, with resultant savings in time and power requirements, increase in production rates and other advantages.
  • FIG. l in the drawings is a broken plan view of one of these new Wire forming machines designed in this particular case for manufacture of ring binders of the type illustrated in Patent No. 2,116,589, In this view the wire is shown entering the machine at the top and first bent into zigzag formation by passage between companion die chains and thereafter entering the grooves in companion die rolls where the bends in the wire are reduced and set to produce the parallel binder ring forming fingers shown issuing from the machine at the bottom.
  • FIG. 2 is an enlarged longitudinal sectional view on substantially the plane of line 2 2 of FIG. l.
  • FIG. 3 is a further enlarged top plan and part sectional view showing a portion of the left hand die roll with the bend closing and setting dies at the end of the groove therein.
  • FIG. 4 is a broken plan view of the companion dies which pinch the tips of the ring forming linger portions of the Wire together into nal shape, as on line 4 4, FIG. 3.
  • FIG. 5 is a broken plan and part sectional view of a portion of the right hand die roll illustrating the die formation for pinching and setting the connecting base portions of the wire.
  • FIG. 6 is a cross sectional detail view of the latter construction on substantially the plane of line 6 6 of FlG. 5.
  • FIG. 7 is a broken part sectional view on substantially the plane of line 7 7 of FIG. l showing how the die forming chains are carried by companion upper and lower sprockets.
  • FG. 8 is a broken plan view of a portion of one of the die chains and showing portions of the mating dies with the wire as it is being bent between them.
  • IFIG. 9 is an edge view of a portion of the left hand die chain.
  • FIG. 10 is a broken sectional detail through companion dies with the wire therebetween, appearing as on substantially the plane of line 1% 10 of FIG. 1.
  • the wire is indicated at il entering one end of the machine through a guide 12 and passing between opposed chains i3, 14 carrying triangular die blades 15, 16 which approach in alternating relation to shape the wire into oppositely projecting relatively pointed and abrupt bends 17, l.
  • the bent wire stock passes between companion die rolls 19, 20 helically grooved at 21, 22 to take the bends 17, 18 in the wire, these grooves decreasing in width and pitch toward the ends of the rolls to squeeze the bends of the zigzag wire into closer formation and to set them into the parallel binder finger formation shown at 23 connected in such spaced parallel relation by the connecting back portions 24, the latter appearing more clearly in FIGS. 3 and 5.
  • FIGS. 3 and 4 As the ring binder forming stock leaves the grooves in the die rolls companion opposed dies 25, 26 at the end of the groove in the left hand die roll 19 pinch the tips of the ring forming portions 23 into close nal position, FIGS. 3 and 4, and companion final forming dies 27, 2S, FIGS. 5 and 6, at the end of the groove in the right hand roll 2t) impart a desired set to the connecting base portions 24 of the formed Wire.
  • the triangular die blades or plates l5 are shown as having relatively abrupt blunt ends 29 to put the ring finger spacing bends 24 in the wire stock and the companion, more pointed lblades 16 are shown as shouldered at 36 to in effect mesh with the blunt tips of the rst blades to give desired spacing formation and set to these bends.
  • FIGS. 8, 9 and 10 show how the chains are made up with the triangular die blades faced on opposite sides by shorter connecting links 31, overlaid by longer cover links 32, with pivot pins 33 projecting through the assembled blades and links and extending far enough at opposite ends to mesh with the teeth of upper and lower drive sprockets 34, 35, FIG. 7.
  • the sprockets of each pair are mounted on shafts 36 in spaced relation, as shown in FIG. 7, to receive between them the connecting links 31, 32 of the chains.
  • Top and bottom guides 40, 4l for confining and holding the wire in position between the bending dies are shown in FIGS. l and 2 and these are continued far enough to insure the zigzag strip clearing the chains and entering properly between the die rolls.
  • top and bottom guides 4t?, 41 side guides are shown at 42, 43, FlG. l, for ⁇ directing the bent wire into proper position between the die rolls. Also a top guide is indicated at 44 in this view for holding the traveling zigzag wire down iiat in riding engagement with the grooves, over the ⁇ bottom support plate 45.
  • Synchronized drive of the sprockets and die rolls is effected in the illustration by chain 46 to a sprocket pinion 47 on the shaft 48 which drives the left hand die roll, FIG. l, said shaft carrying a pinion 49 in mesh with pinion 5t) on shaft 51 carrying a worm 52 in mesh with worm gear 53 on the left hand sprocket shaft 36; power shaft 4S carrying the gear 54 in mesh with gear 55 on shaft 56 connected by gears 57, 5S with shaft 64 carrying worm 59 for the worm gear 6@ of the right hand sprocket shaft 36.
  • the helix rolls 19, 20 carry gears 6i, 62 engaged with gears 54, 55 on the parallel power shafts 43, 56.
  • the wire is drawn into the machine smoothly and continuously by the die carrying chains without stop or interruption and advanced to the final forming rolls which complete the bending operations and set the stock to the final shape.
  • the traveling bending dies effect feeding of the Wire, eliminating need for any wire feeding mechanism and may pull the wire through any usual or special wire straighteners.
  • the dies such as 25, 26 for pinching in and closing the points of the double strand binder ring iingers may be embedded in and lie ush with the surface of the roll 19.
  • the bottom support i5 for the zigzag wire strip is therefore notched as shown at 63 to pass the outreaching die elements 27, 28.
  • the die Yblades which bend the wire into zigzag formation are shaped and spaced to meet in meshing relation Y approximately the distance of the wire diameter apart so as to grip while bending the wire to requisite shape.
  • the extended end portions of the pivoty pins of the chains may be fitted with roller forming sleeves as indicated at 65, FIG. 8, so as to reduce friction in passage of the chains about the Vfixed guides 38, 39 and engagement of the ⁇ pins with ⁇ the sprockets.
  • the top gear 34 maybe provided Iwith adjusting screws 66, FIG. l, engageable with a post 67 projecting up from the bottom gear through a slot 68 in the top gear and with bolts yor screws 69 for clamping the two gears in angularly adjusted relation.
  • the machine illustrated is of relatively simple construction, consisting of but few, rugged parts, which can be produced and assembled at low cost and this machine has the further advantage that ⁇ it is compact and takes up small floor space.
  • a wire forming machine comprising convergentlyr traveling chains having wire forming dies projecting therefromand meeting in alternating order at the point of convergence of the chains, spaced apart a distance approximately the diameter of the wire to be operated on and for bending wire between the same to the approximate shape of the meeting dies and companion rolls at one end Y of said chains having helically extending die grooves positioned to receive the bends pnt in the wire by the coacting dies of the chains, said helical grooves in the die rolls being of decreasing pitch in the direction away from the chains to apply progressive squeezing action on the bends in the wire, the wire bending dies on one chain being pointed to put relatively sharp bends in the wire and the dies on the other chain being blunt ended to put-wider bends in the wire and the 'grooves in the respectiivev die rolls having relatively narrower and wider reducing grooves respectively to receive the relativelyl sharper and wider end bends placed in the WireV by the chains.
  • a wire forming machine comprisingV the combination of endless chains composed of companion at die blades pivotally connected by links at opposite sides of the same and pivot pins extending throughl said links and blades and projecting at opposite endsrbeyond theY- links, companion sprockets spaced apart the thickness of said chains and receiving between them the links of said chains and engaged bythe projecting ends of said pivot pins and whereby said chains are supported and confined between and driven by said sprockets, the blades projecting beyond theV sprockets in thisV relation, the sprockets of the companion chains being located to carry the projecting die blades into converging and overlapping relation, stationary wirev coniining guides over opposite faces of the projecting portions of said converging die blades for maintaining said die blades in alignment and for holding Wire confined between the companion die blades and means for driving the sprocketsV ends of such loops and comprising companion, opposed generally triangular wire forming dies and means for approaching said dies in alternately
