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. |
