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 n 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.
