BAR SHEAR COMPONENTS
The bar shearing station consists of the
guard/guide, hold-down, stationary blade and
moveable blade. Additionally, the bar shear is
activated by a foot switch or by the electric back
gauge.
The visible components of the bar shearing
station include the guard/guide (A), hold-down
(B), and two hand knobs which lock the
guard/guide in place (C).
SHEARING STATION
FOOT SWITCH
The operation of the punching station's foot
switch is described in the Machine Description
section, page C-7.
ELECTRIC BACK GAUGE
The electric back gauge is an automatic feature
which activates the shear shortly after the work
stock comes in contact with the back gauge's
sensor - the machine operator does not need to
press the foot switch. The electric back gauge is
functional when the "Auto / Manual" switch is
turned to "Auto".
The time delay between when the stock contacts
the sensor and when the shear is activated can be
adjusted from 0 seconds to 3 seconds with a timer
in the electrical enclosure.
To Set Up the Electric Back Gauge:
Important: These instruction only describe the
set-up procedure to prepare the back gauge
for operation. Operation of the shear with the
electric back gauge is described in the Angle
Shear Operation section of this chapter.
