Operation
Bulk Pierce Nuts are fed into a Multipierce or Multimatic Head
through plastic nut guide from a gravity or power-feed device.
Force transmitted through the nuts in the plastic nut guide places
a nut under the nut plunger in the "ready" position and, as the
press cycles, the nut is installed. The plunger prevents a new
nut from being placed into "ready" position until a signal is
received from the part probe, at which time air forces the Head to
an "open" position. Until a signal is received from the part
probe the Head will remain in the "closed" position, preventing nuts
from being placed in the "ready"position. The prevents double hits
and potential damage to the die.
Die Design Information
Multimatic Bulk Feed Heads are designed into a die in the same
manner as Multipierce and Multimatic Reel-Feed Heads; same access
requirements exist.
Refer to Multipierce and Multimatic sections for Head mounting
dimensions.
