Application :
Universal Testing Machines have a wide range of applications. A number of materials & metals in different forms & shapes can be tested for a variety of tests like Tension, Compression, Transverse, Bend Re-bend, 180° Bend, Shear, Brinell, Pullout, etc. Special attachments are also available for testing of Flat belts, Chain links, Wire ropes, Nut-bolts.
Construction :
Loading frame: The base has a hydraulic cylinder at its center, and two mains screws at both ends. The middle cross head is mounted on screws through main nuts. The middle cross head can be moved up or down with a speed of approx 300 mm/min through chain transmission and geared motor to adjust the initial tensile / compression clearance. On the piston rests an assembly of upper, lower crosshead and two columns. The individually lapped cylinder piston assembly ensures smooth transfer of force with minimum friction.
Hydraulic system : Hydraulic circuit consists of hydraulic power pack having a directly driven radial plunger pump, which gives a continuous non pulsating flow of oil pressure upto 210 bar. Oil filter, Oil strainer, Air breather, Oil level Indicator, Drain plug are provided on the power pack. A pressure compensated needle type flow control valve is provided to control the oil flow to cylinder thereby achieving desired piston speed. Infinitely variable speeds can be obtained with the help of valves.
Electrical system : A separate switch box and electrical panels are provided. Both the hydraulic pump motor and the geared motor have interlocks. Limit switches are provided to stop the hydraulic pump motor if the load increases beyond the machine capacity or if the piston stroke is exceeded.
Special & Important Features
Front Open Crossheads :
This is extremely useful especially for heavy specimens and bigger capacity machines. In this type of machine the jaws and the inserts also can be easily removed by just pulling from the front. When the jaws and inserts are heavy, it is very difficult to remove them from the machine from upper or lower side. Hence this is an important feature from the point of view of easy operation.
Hydraulic grips : Normally for standard Universal Testing Machines the jaw opening and specimen clamping is effected manually. But this becomes more and more difficult for the operator for higher capacity machines. Also the specimen clamping becomes operator specific in this case. Hence it is a better choice to go for hydraulic operation of jaws (closing and opening). In this hydraulic griping method, separate double acting hydraulic cylinders operate the jaws and the cylinder operation is just by pressing a push button. So the operator has to operate only push buttons, which are conveniently located on the machine, to operate the jaws. A power pack with oil tank, pump, motor oil filler cum breather, oil level indicator, filter, relief valve is provided alongwith an electric motor to drive the hydraulic pump.
Principle of Operation (Optional)
Here Pressure Control Valve and Flow Control Valve are controlled by electronic circuitry in closed loop system to get the desired Loading Rate and Straining Rate. Following control modes are available : Standard Manual Control, Load Rate Control Mode, Strain Rate Control Mode, Load Hold Mode, Load Rate and Strain Rate in single test (one at a time).
Control Range : As per the table. Control Tolerance : ± 5% Load is applied by hydrostatically lubricated Ram. Main cylinder pressure is transmitted to the Pressure Transducer housed in control panel. The Pressure Transducer generates the proportional signal corresponding to Load created by Ram and is given to Electronic Display Unit (DAS Panel). Simultaneously the Optical Digital Rotary Encoder fitted on the straining unit (Lower cross head) gives the mechanical displacement (Cross head travel).
