This computer-controlled spring testing machine is a special testing machine designed and manufactured according to the national standards for spring tension and compression testing machines.
It can be used for testing and analysis of tension, pressure, displacement, deformation, stiffness, and free height of various springs.
Features beautiful appearance, reasonable structure, high rigidity and small deformation of the whole machine.
Using the independently developed spring-specific data processing and acquisition system, it is easier to use and smarter
The machine adopts a fully digital speed regulation system with high speed regulation accuracy and stable performance and a precision motor as the drive system, and a multi-channel controller as the core of the control system. The windows-based data processing software realizes real-time display of test force, test force peak value, beam displacement, test deformation and test curve. All test operations can be completed on the computer.
Test standards
JB/T 7796 Spring tension and compression testing machine standard,
JJF 1134-2005 Calibration specification for special working measuring machine,
GB/T 13634 Calibration of dynamometers for testing machines.
Structure
3.1 Host: This model is different from ordinary tensile testing machines. The mechanical part adopts four-column optical axis and double-screw structure, the whole machine has high rigidity, small deformation, spring hook strength, pressure plate hardness after quenching treatment, tensile strength and compressive hardness are guaranteed,
3.2 Transmission system: It is composed of pulley deceleration system, precision ball screw and guiding optical axis.
3.3 Drive system: The system is driven by precision digital governor and servo motor.
3.4 Measurement control system: The test force measurement control system is composed of high-precision load cells, measurement amplifiers, A/D conversion, and regulated power supply; the displacement measurement control system is composed of photoelectric encoders, frequency multiplier shaping circuits, and counting circuits. Through various signal processing, the functions of computer display, control and data processing are realized.
3.5 Safety protection devices: overload protection, beam limit position protection, overcurrent, overvoltage, overspeed protection, etc.
