PULL PRESSURE (PULL CYCLE)
During a typical full‐pressure cycle, with the Huck‐Spin
fastener in place and the collar threaded on, the opera‐
tor positions the tool nose assembly over the fastener
pintail and presses the trigger.
The Huck‐Spin tool Thimble spins onto the pin threads
until limit switch rod senses enough engagement, which
then directs pressurized hydraulic fluid into the chamber
in front of the tool’s piston, forcing it back, and pushing
the nose assembly’s Anvil forward to swage the collar
onto the pin.
RETURN PRESSURE (RETURN CYCLE)
When proper swage presure is reached, the hydraulic
pressure will be redirected to the rear of the Piston, and
the Anvil will automatically eject off the swaged Collar,
and the Thimble counter‐rotates to unscrew from the
pin.
This results in all tool and nose assembly components
returning to their home positions, ready to install the
next fastener.
