PNEUMATIC AND HYDRAULIC CLAMPS
Power clamping whetherPneumaticor Hydraulic is mostwidely used in the form
of
swing clamps,
which allowunobstructed
part fixturing and placement. The plunger
rod
and the attached clamping arm swings in either a clockwise or counter
clockwise direction, then travels down an additional distance
to
clamp down the foctured part. Upon release
of
clamping
pressure, the clamping arm travels up
to
unclampand swings back in the opposite direction to allowfor part removal and new
part placement.
Different types
of
Pneumatic and Hydraulic Swing Clamps offered by us are illustrated in the following pages of this
catalogue.
1. PNEUMATIC SWING CLAMPS
are used where low clamping forces are needed such as in drilling, tapping or light
machining operations of aluminum components. Also widely used in welding fiXtures. These clamps are most economical
to
useas can
be
operated on in-houseair line.
'TOOLFASr Pneumatic swing clamps are double acting swing cylinders available in different models, shapes and
mountings as illustrated in following pages.

2. HYDRAULIC SWING CLAMPS
are used where medium
to
high clamping force is required such as in machining of
components on conventional orCNC Machines.
Selection
of
type
of
HydraulicCylinder
SingleActing spring return Cylinders
are chosen when there are fewsystem restrictions and there are not manycylinders
(less than 5 cylinders) retracting simultaneously. These arewidely used on conventional machineswhere a hydraulic power
unit is not availableon themachine. SingleActing, Spring return cylinders can also
be
used with hydropneumatic Intensifier.
DoubleActingCylinders
are normally usedwith Hydraulic powerunitsorwithAir drive hydraulic pump which gives required
hydraulicpressure at its outlet by using in-house air at its input. Double acting Cylinders are used when timing sequences are
critical. They are advantageous, as they are less sensitive
to
system back pressures resulting from long
tube
lengths or
numerous cylinders being retracted at the same time. Unclampcycle can also be controlled in double acting cylinders.
Selection
of
Cylinder in terms
of
Clamping force
:
Suitable size
of
Cylinder should
be
selected depending upon the
clamping force required to clamp the work piece. For determination of clamping force required, apart from clamping force
calculation, the best cluecan
be
had from the bolt size being used in the mechanical clamp
of
theexisting fixture.
'TOOLFASr Hydraulic Clamps are available in single as well as double acting cylinders in different models, shapes and
mountings as illustrated in following pages.
