We are Manufacturer, Supplier, Exporter of Spring Testing Machines Model : AIE - STE. Our setup is situated in Kolhapur, Maharashtra, India and majorly we serve customers from African and Gulf countries.
The AIE Spring Testing Machines, Model :AIE STE incorporates design features to enable high accuracy testing with Economy, Speed and Versatility.
AIE Laminated Spring Testing Machine is designed to test laminated springs and coil springs under compression and bending loads.
Operation of the machine is by hydraulic transmission of load from the test specimen through pressure transducer to a separately house load indicator. The system is ideal since it replaces transmission of load through levers and knife edges, which are prone to wear and damage.
Load is applied by a hydrostatically lubricated ram. Main cylinder pressure is transmitted to a pressure transducer house in the control panel. The transducer gives the signal to the electronic display unit, corresponding to the load exerted by the main ram. Simultaneously the encoder fitted on the straining unit gives the mechanical displacement to the electronic display unit. Both signals are processed by the microprocessor and load displacement on digital read outs simultaneously.
Machine consist of :
It consists of a "C" type rigid frame with hydraulic cylinder at its top and an adjustable main testing table is connected to an upper cross head through two screwed columns. This main testing table along with screwed columns can be rapidly adjusted to test height by means of motor. A pair of trolleys is provided on the table to take the horizontal deflection of the spring under loading Laminated springs are tested by placing them on trolleys provided on the table. Coil springs are tested by placing them between the compression plates.
The control panel consists of a power pack complete with drive motor, oil tank, control valves and electronic display unit.
A) 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.
B) Hydraulic Controls :
Hand operated wheels are used to control the flow to, and from the hydraulic cylinder. The regulation in the oil is infinitely variable. Incorporated in the hydraulic system is a regulating valve, which maintains a practically constant rate of table movement.
C) Electronic Control Panel (Series Universal 2001-UTE) :
Microprocessor based panel incorporating state of art technology with following feature.
The Universal 2001-UTE series control panel can be hooked to any PC using RS-232 communication port. AIE offers different exhaustive application, Window based software packages with real time graph on PC to enable the user to effectively evaluated different parameters.
The features include :
AIE Laminated Spring testing machines are closely controlled for sensitivity, accuracy and calibration during every stage of manufacture. Machine is then calibrated over each of its measuring range in accordance with the procedure laid down .
AIE Spring Testing Machine complies with grade "A" and grade 1.0 of IS. An accuracy of + 1% is guaranteed from 20% of the load range selected to full load.
