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 subsequent pages of this website.
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 following series:
» PSF Series Pneumatic,
Flange version, Swing Clamp.
» PST Series Pneumatic,
Screw-in version, Swing Clamp.
» PSB Series Pneumatic,
Block version, Swing Clamp.
2. HYDRAULIC SWING CLAMPS
are used where medium to high clamping force is required
such as in machining of components on conventional or
CNC Machines.
Selection of type of Hydraulic
Cylinder
Single Acting 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 the machine. Single Acting,
Spring return cylinders can be used with hydropneumatic
Intensifier.
Double Acting Cylinders
are normally used with Hydraulic power units or with
Air 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 the mechanical clamp of the existing
fixture.
