FMI Model# RM is a conventional flange line consisting
of a 40' infeed system and a high-speed pinch roll measuring system. As
each flange bar is processed, it is run in continuous mode with weld
splicing. The pinch roll drive system with multiple pneumatic pinch roll
provides linear movement through the machine using an AC servo drive
package. The infeed and outfeed conveyor drives are also AC servos
powered as slave units to the main pinch roll system. The linear
measurement for length and hole location is developed through a
precision measuring wheel system. The heat treated measuring wheels
combined with a high resolution transducer feedback system provides
extremely accurate tolerances to ±.030" up to 60 foot lengths. The
trailing edge of each bar is detected at the automatic weld station and
is positioned for splicing to the next bar. The leading edge of the
first bar is detected by sensors and all punched holes and length
dimensions are located from this zero point.
The punch station provides 196 tons of force and
normally punches two holes on fixed gauge centers from 2½" to 6".
Different gauge centers are acomplished with interchangeable gauge
blocks. Hole diameters to 1¼" can be punched. The automatic shear to
length station consists of a 280-ton hydraulic shear with hydraulic hold
downs. The maximum capacity bar/flange is ¾"x 18" or 1"x 14". The
automatic outfeed conveyor for finished flanges is normally 60' in
length. It incorporates heavy duty kickoff arms and an optional flange
stacking system.
