Power clamping whether Pneumatic or Hydraulic is most widely used in the form of
swing clamps
, which allow unobstructed
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 fixtured part. Upon release of clamping
pressure, the clamping arm travels up to unclamp and swings back in the opposite direction to allow for 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
use as can be operated on in-house air line.
'TOOLFAST' Pneumatic swing clamps are double acting swing cylinders available in different models, shapes and
mountings as illustrated in following pages.

PNEUMATIC AND HYDRAULIC CLAMPS
2. HYDRAULIC SWING CLAMPS
are used where medium to high clamping force is required such as in machining of
components on conventional or CNCMachines.
Selection of type of Hydraulic Cylinder
SingleActing spring return Cylinders
are chosen when there are few system restrictions and there are not many cylinders
(less than 5 cylinders) retracting simultaneously. These are widely used on conventional machines where a hydraulic power
unit is not available on themachine. SingleActing, Spring return cylinders can also be used with hydropneumatic Intensifier.
DoubleActing Cylinders
are normally used with Hydraulic power units or withAir drive hydraulic pump which gives required
hydraulic pressure 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. Unclamp cycle 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 clue can be had from the bolt size being used in themechanical clamp of the existing fixture.
‘TOOLFAST' Hydraulic Clamps are available in single as well as double acting cylinders in different models, shapes and
mountings as illustrated in following pages.
