Definitions

  • One of the purposes of my setting die is to reshape any malformed elements of the snap fastener socket coincident with the setting operation.
  • Another object of my invention is to smooth down or knock off any burrs that may exist and also to provide a sizing operation for the fingers.
  • a further object of my invention is to flex the resilient fingers to reduce their initial stiffness, thereby rendering them more workable for the first attachment to their complementary stud member. This flexing action also tends to loosen any chips caught between the fingers.
  • FiG. 1 is a sectional view of the dies and fastener elements as they appear before the setting operation;
  • FIG. 2 is a similar view showing the dies in the initial state of the fastener assembly operation
  • FIG. 3 is a similar view with the dies positioned in the final state of the fastener assembly.
  • FIG. 4 is a plan view of a socket member.
  • the upper die 10 forms the subject matter of the present invention and consists of a center punch 12 and a surrounding anvil sleeve 13 which may be carried by the plunger of a conventional fastener setting machine (not shown).
  • the punch 12 has a sliding fit within the lower portion of the sleeve 13 and is formed with an enlarged head 14 at its upper end, the undersurface of which is normally abutted against a shoulder 15 provided on the inner wall of the said sleeve.
  • the punch head 14 is held against said shoulder by a relatively heavy coil spring 16 confined within the hollow of the sleeve 13.
  • One type of fastener member on which the upper and lower dies are adapted to operate consists of a socket member 17 and an attaching prong ring 18 having a series of upwardly projecting prongs 19.
  • the socket member "ice 17 is provided with the usual spring fingers 20 terminating in rolled beads 21 of arcuate shape, arranged in a circular formation around the socket opening.
  • a prong deflecting anvil portion 22 Surround ing the fingers is a prong deflecting anvil portion 22 terlminating in 3. rolled rim 23.
  • the anvil portion 22 may be formed with radial ribs 24 as shown in FIG. 4 and are shown in FIGS. 1, 2 and 3 with the sectional view taken through the longitudinal mid-portion of said ribs.
  • the socket fingers may be malformed during manufacture.
  • One example of such malformation is shown in FIG. 4 wherein one of the fingers 20a may be twisted so that the terminal circular bead 21 will not lie in the normal circular formation around the socket openmg.
  • the center punch 12 is formed with a downwardly projecting sizing pin 25 that has tapering sidewalls so dimensioned that as the pin enters the beaded portion of the socket spring fingers, the latter will be sprung outwardly beyond their normal set position.
  • This initial insertion of the sizing pin 25 into the socket spring fingers will impart a flexing operation to the fingers so as to limber them preliminary to their first engagement with a complementary stud.
  • annular recess 26 substantially semi-circular in cross-section that defines a dependent lip 27 at the lower outer edge of the punch with the outer surface of said lip of tapering formation.
  • the recess 26, particularly that portion adjacent the dependent lip 27, is shaped substantially the same as the normal contour of the upper outer surface of the finger beads 21.
  • Another function of this tool is to centralize the spring fingers relative to the surrounding surface of the anvil portion of the socket so they will be in co-axial alignment with each other.
  • the tool serves not only to attach the fastener elements to a support, but also to correct any malformation of the socket and render it satisfactory for its normal working snap action function with a complementary stud.
  • a setting die for snap fastener sockets having resilient central fingers terminating in roiled beads and a surrounding anvil portion, said die comprising a punch having an axially dependent sizing pin and an annular recess surrounding said pin in the lower face of said punch for receiving the rolled beads of said fingers, means on said pin adapted to engage said anvil portion to limit the downward movement of said punch, and a setting die sleeve surrounding said punch and adapted to engage said anvil portion during the setting operation of said socket member upon a support by an attaching prong member.
  • a setting die for snap fastener sockets having resilient central fingers terminating in rolled beads and a surrounding anvil portion, said die comprising a punch having an axially dependent sizing pin and a dependent lip surrounding said pin and defining therebetwecn an annular recess of a contour to substantially embrace the full outer surface of the rolled beads, said lip adapted to engage said anvil portion to limit the downward movement of said punch, and a setting die sleeve surrounding said punch and adapted to engage said anvil portion during the setting operation of said socket member upon a support by an attaching prong member.
  • a setting die for snap fastener sockets having resilient central fingers terminating in rolled beads and a surrounding anvil portion, said die comprising a punch and a setting die sleeve surrounding said punch, said punch being retractable in said sleeve against the influence of a spring confined within said sleeve, said punch having an axially dependent sizing pin and dependent lip surrounding said pin and defining therebetween an annular recess of a contour to substantially embrace the full outer surface of the rolled beads, said die sleeve adapted to engage said anvil portion during the setting operation of said socket member upon a support by an attaching prong member.
  • a setting die for snap fastener sockets having central fingers terminating in rolled beads and a surrounding anvil portion having a series of radial ribs thereon, said die comprising a punch and a setting die sleeve surrounding said punch, said punch being retractable in said sleeve against the influence of a spring confined in said sleeve, said punch having an axially dependent sizing pin and a dependent lip surrounding said pin and defining therebetween an annular recess of a contour to substantially embrace the full outer surface of the rolled beads, said lip adapted to engage the ribs of said anvil portion to limit the stroke of said punch into said socket, said die sleeve adapted to engage said anvil portion during the setting operation of said socket member upon a support by an attaching prong member.
