Application

Adinath Universal Testing Machine is designed to perform tensile, compression, bending and shear tests on metal & other materials, both in the form of test pieces and as finished products.

Principle of Operation

Operation of the machine is by hydraulic transmission of load from test specimen to a separately housed load indicator. The hydraulic system is ideal since it replaces transmission of load through levers & knife edges, which are prone to wear & damage due to shock on rupture of test pieces.

Load is applied by a hydrostatically lubricated ram. The oil pressure in the main cylinder is transmitted to the cylinder of the pendulum dynamometer system housed in the control panel, the dynamometer piston exerts a force proportionate to the hydraulic pressure. This force is transferred through a leverage system to a pendulum.

Displacement of pendulum actuates the rack and pinion mechanism which operates the load indicating pointer.

Return movement of pendulum is effectively damped to absorb energy in the event of sudden breakage of specimen.

Machine comprises of the following:

STRAINING UNIT:

This consists of a hydraulic cylinder piston mounted on a robust base. The loading frame consists of an upper crosshead, middle crosshead and lower table.

The upper crosshead and lower table is connected by means of two plain hard chrome plated columns. The middle crosshead is fitted on two hard chrome plated threaded columns. A reduction gear motor drives the chain and sprockets fixed at the bottom of the threaded columns for height adjustment.

The cylinder and ram is individually lapped to eliminate friction. Axial loading of the ram is ensured by relieving the cylinder & ram of any possible side loading by the provision of ball seatings.

An elongation scale with least count of 1mm is provided for measurement of deformation on various samples.

Tension test is conducted by gripping the test specimen between the upper and middle crosshead.

Compression, Transverse, Bending Shear and hardness tests are conducted between the middle crosshead and the lower table

Control Panel

The control panel consists of a power pack complete with drive motor and oil tank, control valves, a pendulum dynamometer, a load indicator system and 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 System:

Hand operated 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.

Pendulum Dynamometer

The oil pressure in the main cylinder actuates the special dynamometer system. Pressurised oil in the loading cylinder pushes up the measuring piston proportionately and deflects the pendulum. The piston is constantly rotated to eliminate friction. The system has effective damping arrangement to ensure smooth return of pendulum after sudden breakage of test piece. This unit permits selection of favourable hydraulic ratios producing relatively small frictional forces.

Load Indicating System:

This system consists of a large dial and a pointer. Displacement of pendulum actuates the rack and pinion mechanism, which operates the load indicating pointer. The pointer moves over a large dial indicating the load. A dummy pointer is provided to register the maximum load reached during the test. Window type dial is provided for easy and clear changing of load range.

Autographic Continuous Roll Load-Elongation Recorder

A continuous roll ( A strip chart ) type load-elongation recorder is provided for plotting load-elongation graph. Horizontal movement of the rack produces load ordinate of the diagram and drum rotation to elongation ordinate, in the ratio of either 1 :5 or 1 :10.
