Application :
FIE Universal Testing Machine is
designed for testing metals and other
materials under tension, compression
bending, transverse and shear loads.
Hardness test on metals can also be
conducted.
Principal of Operation :
Operation of the machines is by
hydraulic transmission of load from the test
specimen to a separately housed load
indicator. The hydraulic system is ideal
since it replaces transmission of load
through levers and knife edges, which are
prone to wear and damage due to shock on
rupture of test pieces.
Load is applied by a hydrostatically
lubricated ram. Main cylinder pressure is
transmitted to the cylinder of the pendulum
dynamometer system housed in the control
panel. The cylinder of the dynamometer is
also of self-lubricating design. The load
transmitted to the cylinder of the
dynamometer is transferred through a lever
system to a pendulum. Displacement of the
pendulum actuates the rack and pinion
mechanism which operates the load indicator
pointer and the autographic recorder. The
deflection of the pendulum represent the
absolute load applied on the test specimen.
Return movement of the pendulum is
effectively damped to absorb energy in the
event of sudden breakage of a specimen.
Machine consists of :
Straining Unit
This consists of a hydraulic cylinder
motor with chain and sprocket drive and a
table coupled with the ram of the hydraulic
cylinder, mounted on to a robust base. The
cylinder and the ram are individually lapped
to eliminate friction. The upper cross-head
is connected to two screwed columns which
are driven by a motor. Axial loading of the
ram is ensured be reveling the cylinder and
ram of of any possible side loading by the
provision of ball seatings.
An elongation scale with a minimum
graduation of 1 mm, is provided to measure
the deformation of the specimen.
Tension test is conducted by gripping the
test specimen between the upper and lower
cross-heads,
Compression, transverse, bending, shear and
hardness tests are conducted between the
lower cross head and the table.
The lower cross-head can be raised or
lowered rapidly by operating the screwed
columns thus facilitating ease of fixing of
the test specimen.
Control Panel :
The control Panel consists of a power pack
complete with drive motor and an oil tank,
control valves a pendulum dynamometer a load
indicator system and an autographic
recorder.
Power Pack :
The power pack generates the maximum
pressure of 200 kgf/cm2 the
hydraulic pump provides continuously
non-pulsating oil flow. Hence the load
application is very smooth.
Hydraulic Controls :
Hand operates wheels are used to control the
flow to and from the hydraulic cylinder. The
regulation of oil flow is infinitely
variable incorporated in the hydraulic
system is a regulating valve which maintains
a practically constant rate of piston
movement. Control by this valve allows
extensometer readings to be taken.
Load Indicator System :
This system consists of a large dial and
a pointer. A dummy pointer is provided to
register the maximum load reached during the
test. Different measuring ranges can be
selected by operating the range selection
knob. An overload trip switch is
incorporated which automatically cuts out
the pump motor when the load range in use is
exceeded.
Pendulum Dynamometer :
This unit permits selection of favorable
hydraulic ratios producing relatively small
frictional forces. Pressurised oil in the
loading cylinder pushes up the measuring
piston proportionately and actuates the
special dynamometer system. The piston is
constantly rotated to eliminate friction.
The dynamometer system is also provided with
an integral damper and ensures high
reliability of operation. The load
transmitted to the dynamometer is
transferred through a pendulum to the load
indicator.
Autographic Continuous Roll
Load-Elongation Recorder :
This unit is of the pen and drum type
and is supplied as standard. The horizontal
motion of the pen produces the load ordinate
of the diagram and the drum rotation
produces the extension ordinates in the
ration of either 1:5 or 1:10.
Accuracy & Calibration :
AII FIE Universal Testing Machines are
closely controlled for sensitivity, accuracy
and calibration during every stage of
manufacture. Every machine is then
calibrated over each of its measuring ranges
in accordance with the procedure laid down
in BS : 1610 : Part 1 :1992 and IS 1828 :
(Part 1) : 1991.
FIE Universal Testing Machines comply with
Grade "A" of BS : 1610 : Part 1:1992 and
class 1 of IS 1828 : (Part1) : 1991
An accuracy of + 1.0% is guaranteed
from 20% from 20% of the load range selected
to full load. Below 20% of the selected
range, the maximum permissible error is 0.2%
of the full load reading. |
