Computer-Controlled Spring Tension and Compression Testing Machine (Gantry Type)

The Microcomputer-Controlled Automatic Spring Tension and Compression Testing Machine (Gantry Type) is a high-precision testing machine designed for the mechanical performance testing and quality control of various springs. It can accurately measure tension force, compression force, displacement, deformation, stiffness, and other mechanical properties.

Main Applications

Manufactured in accordance with the technical requirements specified in JB/T 7796-1995. JB/T 7796-2005. Spring Tension and Compression Testing Machine—Test Methods, and JIS B 7738-1993. Testing Machines for Compression and Tension of Helical Springs.

The machine is designed for strength testing and analysis of tension force, compression force, displacement, deformation, and stiffness of various 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 screw mechanism drives the compression platen upward and downward to perform compression and other mechanical performance tests.

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

Testing Functions

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

Determine whether the spring meets 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 spring qualification.

Perform segmented measurements and calculate the stiffness K (spring rate) and average stiffness of each section.

Support both sampling inspection and batch testing, with a batch-testing fixture available for the mechanical section.

Main Functions

Automatic Range Switching: Automatically selects the appropriate measurement range according to the applied load to ensure measurement accuracy.

Test Condition Storage: Test parameters and specimen conditions can be saved as modules for convenient batch testing.

Automatic Speed Adjustment: Crosshead speed can automatically change according to a preset program or be adjusted manually during testing.

Automatic Data Saving: Test data and curves are automatically saved after each test.

Computerized Test Process: Testing, measurement, display, and data analysis are completed by the computer.

Batch Testing: Multiple specimens with identical parameters can be tested sequentially after a single parameter setup.

Test Software: Windows-based interface with menu prompts and mouse operation.

Dynamic Display: Test data and curves are displayed dynamically throughout the testing process.

Curve Analysis: Completed test curves can be reviewed and analyzed, with corresponding test data available for any selected point on the curve.

Test Report: Test reports can be generated and printed according to user-defined formats.

Limit Protection: Equipped with both software-controlled and mechanical limit protection for safe operation.
