UTS-NW-GV Computer Controlled Automatic Spring Torsion Testing Machine (Vertical Type) is mainly suitable for testing torsional mechanical properties of various torsion springs and elastic elements. Measuring the torque of a spring at any angle of rotation or at any torque can also be used to test the torsional properties of other elastic elements. The user can adjust the test program according to the actual needs in use, and the operation is extremely convenient. The computer control system controls the control of the test process and the automation of data processing, and the test report is diversified such as curve charts, EXECEL, text files, etc.
The product is widely used in torsional springs, single torsion springs, double torsion springs, spiral torsion springs, vortex springs, and spring springs torsional mechanical properties test. It is suitable for spring factory, machinery manufacturing, auto parts, quality supervision, metrology, quality inspection, commodity inspection industry, metallurgy, aerospace, nuclear engineering and other test fields.

Basic parameters of spring mechanical properties:
Test force: the object is subjected to an external force that causes it to deform and its torsional force. Deformation: The angle at which the object is deformed under the action of external force.

2.1, Mechanical

This series of testing machines is a new generation of testing machines produced by our company. Through the mechanical finite element analysis, the force of the main frame is more reasonable, and the stiffness and strength of the frame are fully guaranteed. The moving part of the equipment adopts a zero-gap ball screw pair to adjust the test space, which not only ensures the accuracy of the test results but also ensures the service life.

2.2, Electrical
1) The testing machine adopts AC servo system and motor drive, with reducer to decelerate, to ensure that the testing machine can have a high deceleration ratio, and the noise is small, the life is long, the transmission is stable, and the performance is stable and reliable. It has protection functions such as overload, overcurrent, overvoltage, emergency stop, etc.
2) Support a variety of control methods, including:

• forward rotation and fixed angle torque measurement;

• Forward rotation fixed torque measurement angle;

• Reverse and angle measurement torque;
