Definitions

  • a device for simultaneously obtaining the tapering and the flanging of the bodies of metal cylindrical cans comprising in combination one pair of spindles symmetrically located on a common axis, capable of revoluting about said axis and destined to slide along said axis in order to enter into the worked body and to issue from the body itself when the operation is ended, a negatively shaped surface on the inner ends of said spindles reproducing the shape to be obtained in said cylindrical body, a pair of shaping collars idly mounted on said spindles and provided in their inner surface with the positive shape corresponding to that of the spindles, means for holding centered said collars and for allowing a progressive radial displacement thereof, so as to deform the said interposed cylindrical body, according to the aforesaid shape.
  • the present invention relates to a device for simultaneously tapering and flanging the bodies of metal cylindrical cans. to be used on an automatic machine with multiple operative elements.
  • a more widely known system which embodies simultaneously the two operations, is based on the principle of operating two half-rings provided internally with the profile of the tapering, and half-rings when gripping the workpiece compressing the surface of the edge of the body about a stationary cylinder, where in correspondence with the half-rings, the circumferential shaped groove, of the tapering to be obtained, has been provided.
  • the device according to this invention aims to use the new working techniques and the new mechanical characteristics of the tinned plate used for manufacturing the metal cylindrical bodies.
  • This device in fact, when applied on automatic machines with multiple operative elements, allows a high rate of production to be reached, obtaining at the same time the tapering and the flanging of cylindrical bodies by a single operation by a process of gradual deformation of the material (as required by its novel mechanical features).
  • the device includes:
  • HO. 1 shows a partial view of the automatic machine with multiple operative elements, already mainly used for receiving thereon the members forming the system for obtaining the tapering and the flanging of metal cylindrical bodies.
  • FIG. 2 shows a cross-sectional view of the machine of FIG. 1, on a reduced scale, wherein the feeding system of the worked bodies to the various operative elements is shown.
  • FIGS. 3 and 4 show the longitudinal sectional view of the members forming the system for tapering and flanging the bodies, mounted on the shafts of the operative elements, in different working positions.
  • FIG. 2A shows a partial sectional view of the machine itself, where the stationary cam for the progressive approach of the shaping collars against the spindles has been shown.
  • the operative elements 1 and 2 are located symmetrically by pairs, on the rotating unit of the machine formed by the drums 3 rigid with the rotary shaft 4.
  • the elements 1 and 2 are given axial movement by the stationary cams 5 for inserting the spindles 6 and 7 into the cylindrical body 8 for carrying out the tapering and flanging ope rations, and for extracting the spindles in order to render free the body 8 when the operation has been completed.
  • the revolution of the shafts 9 is obtained by the gears 10 mounted thereon, engaged with the two gears 11 stationary and rigid with the cams 5.
  • the bodies 8 to be worked are fed to the machine by means of the feeding unit of FIG. 2 consisting of a conveying screw 12 and of two pairs of star members 13 and 14.
  • the star members 13 synchronous with the screw l2 take up the bodies 8 carrying them on the centering and conveying supports 15 so as to feed the various operative elements of the machine.
  • the star members l4 synchronous with the centering supports 15 take up the bodies rendered free from the spindles 6 and 7 after the required operations have been carried out, carrying the worked pieces in the collecting channel 16.
  • the device according to the present invention shown in FIGS. 3 and 4 comprises: a pair of spindles 6 and 7 rotating on the shafts 9 of the operative elements 1 and 2 which during their axial movement introduce the spindles themselves 6 and 7 inside the workpiece 8. centering them on one another by means of the hub l7 and of the chamber 18 provided thereon.
  • the grooves 19 On the external ends of the spindles 6 and 7 are circularly provided the grooves 19 corresponding to the tapering and flanging profiles to be obtained. Said grooves end in the projecting flanges 20 provided on the spindles 6 and 7, and used for axially centering the body 8.
  • the collars 21 which are positioned and held with respect to the spindles 6 and 7 by their flanges 23, which are guided between the surfaces of the flange 31 of the sleeve 30 and the flange of the spindles 6 and 7, are driven during their contact with the cams 4
  • HO. 3 shows a cross sectional view of the members of the unit in their working condition, wherein the spindles 6 and 7, introduced into the work piece 8 are engaged with one another, while the shaping collars 2i arc co-axially centered with the respective spindles 6 and 7 by means of the cones which are elastically pushed into the recesses 24 of the associ ated collars 21.
  • FIG. 4 shows the device during the tapering and flanging operations on the last portion of the rolling race 40 of the cam 4].
  • Apparatus for simultaneously tapering and flanging the bodies of cylindrical metal cans comprising a pair of spindles, shafts mounting said spindles for rotation about and sliding movement along a common axis toward and away from each other so as jointly to sup port a said can when said spindles are together, each spindle having a negative surface on its inner end for shaping one end ofa said can, a pair of shaping collars idly mounted on said spindles and having an inner surface having a positive shape corresponding to said negative shape but of a larger diameter than the diameter of said negative shape, each said spindle having a centering end flange for a said can.
  • said means for radially displacing said collars comprising a pair of stationary cams engaging with a cylindrical peripheral surface on each said collar that rolls on a said cam.
