Application - Universal Testing Machine
'FIE' Electronic Universal Testing Machine is designed for testing materials and other materials under tension, compression bending, transverse and shear loads. Hardness test on metals can also conducted.
Machine Consists of -
Straining unit - Universal Testing Machine
This consists of a 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 rigidly fixed to the table by two strengthened columns.
The lower cross-head is connected to two screwed columns which are driven by a motor. Axial loading of the ram is ensured by relieving the cylinder and ram of any possible side loading by the provision of ball seating.
An displacement scale, with a minimum graduation of 1mm, 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.
Typical HGFL design includes a basic Universal Testing Machine frame with open type crossheads and hydraulic wedge action grips.
Control Panel - Universal Testing Machine
The Control Panel consists of a power pack complete with drive motor and an oil tank, control valves and electronic display unit.
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.
Accuracy and Calibration - Universal Testing Machine
FIE Electronic Universal Testing Machine is closely controlled for sensitivity, accuracy and calibration during every stage of manufacture. Machine is calibrated over each of its measuring range in accordance with the procedure laid down in British standards 1610: Part1: 1992 and IS 1828: Part1: 1991
FIE Electronic Universal Testing Machine complies with Grade “A” of BS: 1610:Part1:1992 and class 1 of IS-1828-Part1:1991.
Hydraulic Controls - Universal Testing Machine
Hand operated wheels are used to control the flow to and from the hydraulic cylinder.
The regulation of the 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 reading to be taken. Another Power pack is used to operate wedge action grips by means of hydraulic cylinder by using solenoid valve operation
For Hydraulic Wedge action grips separate control remote is provided with selector switches indicating clamp – declamp and null positions.
Principle of operation for-
Model : UTN -HGFL : - Universal Testing Machine
Operation of machine 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 historically 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 represents the absolute load applied on the test specimen.
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 represents the absolute load applied on the test specimen.
Load indicator System (Analogue) :
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.
Displacement - Universal Testing Machine
An elongation scale, with a minimum graduation of 1mm, is provided to measure the deformation of the specimen.
Pendulum Dynamometer - Universal Testing Machine
This unit permits selection of favorable hydraulic ratios producing relatively small frictional forces.
Pressurized 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.
