Computer-Controlled Spring Tension and Compression Testing Machine

The Computer-Controlled Spring Tension and Compression Testing Machine is a precision testing instrument designed for the mechanical performance evaluation of various springs. It can measure and analyze tension force, compression force, displacement, deformation, stiffness, and other mechanical properties of spring specimens.

Main Applications

Manufactured in accordance with the technical requirements specified in the Chinese Machinery Industry Standards JB/T 7796-1995 and JB/T 7796-2005. Spring Tension and Compression Testing Machine—Test Methods, as well as JIS B7738-1993. Testing Machines for Compression and Tension of Helical Springs.

The machine is suitable for strength testing and analysis of tension force, compression force, displacement, and spring stiffness of precision springs, including tension springs, compression springs, disc springs, conical springs, leaf springs, retaining springs, flat springs, composite springs, gas springs, die springs, and special-shaped springs.

The computer system controls the servo motor through the controller and speed-control system. After speed reduction, the precision ball screw mechanism drives the compression platen upward and downward to perform compression and other mechanical property tests on the specimens.

The machine adopts a fully digital servo speed-control system with high speed-control accuracy and stable performance, together with a servo motor as the drive system. The controller serves as the core control system. Windows-based control and data-processing software enables real-time display of test force, peak test force, crosshead displacement, test deformation, and test curves. All testing operations can be automatically performed through the computer using a mouse.

Testing Functions

Determine whether a spring meets the specified requirements by measuring the corresponding force F at a specified deformation ΔH or compression height H.

Determine whether a spring meets the specified requirements by measuring the corresponding deformation ΔH or height H under a specified spring force F.

Perform single-point or multi-point testing to determine whether the spring meets the specified requirements.

Perform segmented measurements and calculate the stiffness K (spring rate) and average stiffness for each segment.

Support both sampling inspection and batch testing. A batch-testing fixture is available for the mechanical section.
