Definitions

  • a means for actuating the tool holder include a gear mounted parallel to the tray and meshing with pinions distributed about the gear, each of these pinions being secured on a shaft carrying a cam controlling the advance of the tool holder, which is spring urged rearwardly PATENTEU AUG24
  • This invention is concerned with an automatic machine for the manufacture of springs from steel wire.
  • the invention has for its subject an automatic machine for the making of springs from steel wire, in particular for the watch-making industry, comprising a tray carrying two holders positioned ringwise above the center of the tray and radially slidable in the direction of the center of the tray with tools for keeping the spring from a wire issuing from the center of the tray.
  • This machine is characterized by the fact that the means for controlling the two holders comprise a gear parallel to the tray meshing with pinions fitted about the gear, each of the pinions being secured on a shaft carrying a cam controlling the advance of the tool holder, the withdrawal of which is ensured by a spring.
  • FIG. 1 shows an elevational and longitudinal cross-sectional view of a part of the machine.
  • FIG. 2 shows an elevational longitudinal cross-sectional view of another part of the machine.
  • FIG. 3 shows a front detail view thereof.
  • FIG. 4 shows a partial cross-sectional view along IV-lV of FIG. 3.
  • FIG. 5 shows a partial cross-sectional view along V ⁇ / of FIG. 3.
  • the machine comprises a frame 1 in which is secured a tray 2 carrying 12 tool holders 3 positioned ringwise or fanwise about the center of the tray occupied by a rolling stud 4 in the perimeter of which issues the steel wire feeding the machine.
  • On the sliding tool holders are secured tools 6 which operate successively to wind the wire about stud 4. At least one of these tools is so shaped as to bend the wire against flange 7 carrying the rolling stud.
  • a first shaping of the spring can be effected by means ofa slidable spindle 8 which has alternating rotary movements and whose hollow extremity surrounds stud 4 and drives the wire in its rotational movement above stud 4.
  • the tools 6 can be used to wind the spring about spindle 8, after immobilizing the same, in order to form a second loop.
  • the tool holders 3 are constituted by sliders (FIG. 5), having a dovetail moving in a slide 9.
  • Tools 6 are secured removably to the extremity ll] of the tool holder (FIG. 3).
  • Slides 9 are themselves removably secured by means of a screw on tray 2. The withdrawal of the tool holders is ensured by a spring 51 bearing by one of its extremities against the washer 11 and by further extremity against the unthreaded extension of the screw l2.
  • each tool holder is ensured by cam 13 mounted at the end of shaft 14 rotating in two ball bearings and carrying at its other extremity a pinion 15 meshing with a gear 16 rotated about a cylindrical shoulder l7 of tray 2 on a needle bearing l8.
  • This gear 16 itself driven by a gear l9 meshing with a pinion 20 cut on a shaft 21 carrying cams 22 and 23 for the control of the clamping and cutting of wire 5, a gear 24 with conical teeth meshing with a similar gear 25 whose shaft carried a set of earns 26 for controlling the advance of the wire, shaft 21 carrying additionally a gear 27 controlling the movement of spin le to the intermediary of the gear train and a toothed segment 28 to which is imparted an alternating movement and a bell cam 29 controlling the advance of the spindle.
  • cams 13 act on the tongue 30 on the corresponding tool holder, this tongue being integral with the nut of a micrometric screw 31 which allows to adjust precisely the path of tool 6.
  • An automatic machine for the manufacture of steel wire springs in particular for the watchmaking industry comprising a tray, a plurality of tool holders positioned in ringwise fashion about a centrally disposed axis of said tray, said tool holders being radially slidable toward said axis of said tray; spring shaping tools carried by said tool holders for shaping wire issuing from said center of said tray; means for moving said tool holders including a gear mounted parallel to said tray, a plurality of pinions distributed about said gear and disposed in mesh therewith, one pinion for each said tool holder, a plurality of shafts respectively fixed to said pinions, a plurality of cams, one on each said shaft, for controlling the advance of said tool holders in the direction of said axis of said tray, and spring means for retractably urging the said tool holders.
