Operation
Strip Pierce Nuts are fed from nut reels, through a plastic nut
guide, into the Reel-Feed Adaptor. Spring force, transmitted
through a feed pawl in the Reel-Feed Adaptor, pushes the strip of
nuts into position in the Head. The nut plunger shears off one
nut at a time and installs it in the part. During the
installation cycle, the cam on the base of the the Head retracts the
spring-powered feed pawl so that, on the upstroke, another nut is
automatically fed into position under the plunger. The cycle
repeats itself during each stroke of the press with Multipierce
Heads, and "on command" with Multimatic Heads.
Die Design Information
- Counterbore upper die shoe for cylinder cap and air supply
line.
- Position each Head to allow access to the proximity probe.
- Punch support base is ported on both sides; cylinder cap may
be rotated to allow air line connections to suit installation
needs.
- Air supply requirements: filter, pressure regulator @
40 psig, lubrication unit, air line connections, solenoid valve
(momentary type, 4-way, with no spring return) and part probe.
System Components
In addition to the Multimatic Head, six basic components are
required for system operation:
- Part Probe: signals solenoid valve when panel is in
proper position (so supply air pressure to open Head).
- Rotary Cam Limit Switch: signals solenoid valve when
press stroke is at 190° (so supply air pressure to close Head).
- Four-Way Solenoid Valve: transfers air supply pressure
to upper manifold to open Head (on signal from part probe) or to
lower manifold to close Head (on signal from rotary cam limit
switch).
- Upper Manifold: distributes air pressure to open Head.
- Lower Manifold: distributes air pressure to close
Head.
- F-R-L Unit: filters, regulates and lubricates air
supply.
