Definitions

  • My invention relates to a device for enabling split insulating washers to be cut out as they are mounted on an electric conductor which is fed through the device. This arrangement makes it possible, in particular, to supply a machine for manufacturing coaxial cables operating in a continuous manner.
  • the electric conductor is fed through the axial passage of a main punch which is adapted to cut out, round the conductor, a washer from a strip of insulating material which moves, step by step, at right angles to the conductor, owing to the fact that preparatory slots are punched beforehand by auxiliary punches in the axis of the strip and successively straddle the conductor.
  • Fig. l is a diagrammatic general view of the device according to the invention.
  • Fig. 2 is a detail view in horizontal section, on a larger scale, of the cutting tool provided with the strips of insulating material.
  • Fig. 3 is a detail view showing the various punching operationseffected on the strips which have been shown displaced with respect to one another for the sake of the clarity of the drawing, but which are. in reality, located on top of one another.
  • Fig. 4 shows a washer after it has been completed.
  • Figure 5 is a detail view, drawn to a larger scale, showing a suitable device for driving step by step the strips of insulating material.
  • Figure 6 is a detail view showing a suitable device adapted to drive the electric conductor.
  • Figure 7 is a detail view showing a device for gauging the insulating strips.
  • the device essentially comprises a framework I along which a press-head i is adapted to 'slide by the action ot an eccentric 9 which imparts a reciprocating movement thereto.
  • the press-head l supports a cutting tool I0 which essentially comprises (see Fig. 2): a central punch I I provided with an axial passage I2 through which the conductor 5 can slide loosely; two lateral prepartory punches I3 and Il for the two strips I and I and nnally a die of appropriate shape I5.
  • the two strips I and I' are fed into the cutting tool I0 in opposite directions to one another by the respective action of two groups of feed rollers I6 and I1 which are intermittently driven in the direction of the arrows and at such proper timing that the feed occurs only at the time when punches Il, I3 and Il are out of engagement with the strips I and I'.
  • each group of rollers I6 and I1 one of the rollers (see Fig. 5) is driven inter mittently in the direction of the arrow, by means of a ratchet device I8 in its turn subjected to the action of a control lever I9.
  • a rod 20 pivot ing at one of its ends on the movable head 8 can slide in a guide fork 2l of the lever I9.
  • This roei 20 is provided with a stop 22 and, on its free end. with a. spring 23.
  • the catch 24 is automatically actuated by the free end of a retracting rod 25 which is pivoted at its other end on the member 8.
  • the spring 23 is released and urges the lever I9, whereby the strip I' is fed forward.
  • the device operates as follows:
  • the lateral preparatory punches I3 and Il cut out from each of the strips I and I' a slot 3 with a circular head 2 (see Fig. 3). It is obvious that during this cutting out period, the strips remain locked in the cutting tool I0. They start their movement again, in opposite directions to one another, by the action of the rollers IB and I1, as soon as the punches. which are moved backwards by the press-head l, have disengaged the strips. This movement of the strips continues until the instant when the conductor 5, which is engaged in the slots 3 which have just been formed by the lateral punches. abuts against the respective bottoms of said slots. The same conditions then obtain again as at the beginning of the cycle which has just been described.
  • a device for placing split insulating washers in position on an electric conductor which comprises a main punch provided with an axial passage, means for feeding the electric conductor inside said passage, means for feeding step by step, at right angles to the conductor, a strip o! insulating material provided with preparatory axial slots which successively straddle the conductor, an auxiliary punch for cutting out the preparatory axial slots, which is displaced relatively to the main punch such a distance that when said main punch cuts out a washer from the strip, the opening made thereby joins the leading end of the next preparatory axial slot, and means for actuating said punches during the time when the strip of insulating material is stationary.
  • a device for placing split.lnsulating washers in position on an electric conductor which comprises a main punch provided with an axial passage, means for feeding the electric conductor inside said passage, means for feeding step by step, at right angles to the conductor, a plurality of strips of insulating material which are provided with preparatory axial slots which successively and at the same instant for each strip straddle the conductor, auxiliary punches for cutting out said preparatory axial slots, said auxiliary punches being displaced relatively to the main punch such a distance that when said main punch cuts out contiguous washers from said strips, the openings made thereby join ihe leading ends oi the next preparatory axial slots and means for actuating said punches due'urfi th i me when the strips of insulating material are stationary.
