Automatic Mechanical Universal Testing Machine, Color : Green

We are one of the major Manufacturers, Exporters and Suppliers of Mechanical Universal Testing Machines in Ichalkaranji (India). The Mechanical Universal Testing Machines are widely used for the various tests on the metals and other materials like the tensile, compression, bending and shear tests. The test pieces as well as finished products can be tested by the means of Mechanical Universal Testing Machines. The Mechanical Universal Testing Machines transfers loads Highlights Of Mechanical Universal Testing Machines :

• Loading Accuracy: As high as + 1 %
• Designed for best man-machine interaction
• Printer/plotter interface
• Globally traceable pressure transducer
• µp/PC based option
• Variable pace of training for suiting a wide range of materials
• Auto graphic recorder with continuous roll as standard that enables material behavior study
• Threaded columns driven by motor provide fast and effortless lower cross head adjustment and facilitate rapid fixing of sample
• Large size and dial design helps in highly accurate reading
• Easy change from plain to threaded and screwed specimens
• Various standard and special accessories, including load stabilizer
• Samples and structures can be tested by the means of large effective clearance between the columns
• Simple, safe and easy to use with safety devices
• Robust construction
• Fully enclosed and protected pendulum

Principle Of Operation :

• Operation of the machine is by hydraulic transmission of load from test specimen to a separately housed load indicator, which is better as compared to the use of levers and knife edges, since this limits the scope of wear and damage due to shock on the 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 that is transferred to a pendulum by the leverage system
• Displacement of pendulum actuates the rack and pinion mechanism which operates the load indicating pointer
• In case of sudden breakage of the sample, the return movement is effectively damped to absorb energy

Parts Of Mechanical Universal Testing Machines :

• Straining Unit :
• Consists of a hydraulic cylinder and piston mounted on a robust base
• Loading frame has an upper crosshead, middle crosshead and lower table
• Two plain hard chrome plated columns connect the upper crosshead and lower table
• Two hard chrome plated threaded columns to fit the middle crosshead
• Reduction gear motor for driving the chain and sprockets that are present at the bottom of the threaded columns and provide height adjustment
• Individually lapped cylinder and ram to limit friction
• Axially loaded ram ensured by the relieving the cylinder
• Ram of any possible side loading by the provision of ball seating
• Elongation scale with least count of 1mm for measuring sample deformation
• Tension test between the upper and middle crossheads by gripping the test specimen Other tests for compression, transverse, bending shear and hardness conducted between the middle crosshead and the lower table
• Control Panel : Consists of a power pack that consists of a drive motor and oil tank as well as control valves, a pendulum dynamometer, a load indicator system and autographic recorder
