MultiPierce Reel Feed Design Info

Operation

Strip Pierce Nuts are fed through a Reel-Feed adaptor connected to the head assembly.  The nuts are fed automatically into ready position.  The press, when lowered, forces the plunger to drive the nut into the part, supported by a die button.  The die button forms the part material into and around the Pierce Nut undercuts and/or clinches the nut corners, securing the nut in position.

Die Design Information

  • Other operations may be included in dies installing nuts.
  • Counterbore upper die shoe for shank and spring.
  • Part and nut sensing is suggested for most applications.
  • Show oil lines, fittings and manifolds for multiple Head installations on drawings.
  • If possible, position each Head to allow access to the proximity probe, oil hole on side of base and shank travel pin.
  • Allow room for entry of the Reel-Feed adaptor and Plastic Nut Guide.  Arrange Head so Plastic Nut Guide does not interfere with press operation.
  • Piercing up from lower die shoe is possible; consult your representative for slug clearance hole requirements.
  • For all unique or special applications, consult your representative.
