Spring Tension and Compression Testing Machine (Gantry Type)
Category：Torsion Testing Machine
Introduction
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.
