Testing Machine Introduction:

This machine is primarily used for testing the torsional mechanical properties of metal materials and specimens such as bolts, tools, finished products, structural components, drive shafts, parts, and fasteners at room temperature or under special conditions. It can also be used for torsional failure testing of non-metallic materials and finished products. The specimens are mounted between adjustable fixtures, adapting to different torsional mechanical properties tests.

Based on standards:JB/T 9370-2015 "Technical Specification for Torsion Testing Machines," GB/T 10128 "Room Temperature Torsion Test Method for Metallic Materials," JJG 269 "Verification Procedure for Torsion Testing Machines," etc.

Application Industries: Metrology and Quality Inspection, Metallurgy and Steel, Machinery Manufacturing, Fasteners, Hardware Tools, Automotive Parts, Universities, Research Laboratories, etc.

Engine Structure and Electrical System Introduction:

The mainframe utilizes a horizontal steel plate structure, which is formed in one step to ensure high overall rigidity. The test space is adjustable. The torque disc is connected to a sensor for torque collection, while the other end is for torque loading. A precision CNC servo motor, driven through a cycloidal reducer, drives the force disc to rotate, applying torque to the specimen. The torque collection end can be moved along a linear guide to adjust the test space and clamp the specimen. An environmental test chamber can be installed if necessary.

Transmission System:

A precision CNC motor, driven through a precision reducer, drives the force disc to rotate, applying uniform torque to the specimen, ensuring continuous speed adjustment and uniform loading over a wide range during the test.

Torque and Torsion Angle Measurement:

A high-precision torque sensor is used to measure torque in both positive and negative directions. The torsion angle is directly connected to the specimen area, avoiding the errors associated with motor angle encoders used by some manufacturers and ensuring accurate and reliable angle display. The collected sensor signals are processed by a computer data acquisition and processing system and displayed in real time on the computer screen.

Measurement and Control System:

The entire test process utilizes Windows-based, graphically interfaced software. The software simultaneously displays curves of the tested specimen's torque versus time, torque angle versus time, torque versus torque angle, and torque versus rotational angle. Parameters such as torsion angle, torque value, and peak torque are displayed in real time. Test results can be generated in Word or CXCEL report formats for convenient storage, printing, and analysis.

Test Procedure:

Select an appropriate specimen and adjust the test space according to the specimen length. Place the specimen on the workbench, insert one end into the clamping block with the corresponding clamp. Slowly push the movable base to slowly feed the specimen into the clamping block at the other end. Tighten the clamping block with the Allen wrench to confirm that the specimen is installed. Finally, perform the corresponding mechanical test using the torsional mechanical measurement and control software.

General Function Overview:

This software consists of modules for dynamic communication, speed control, parameter input, data processing, result observation, record query, chart display, chart printing, and data storage.

Diverse testing methods are available. You can set the material's torque and test its torsion angle; you can also set the material's torsion angle and test the torque, automating the entire testing process.

Can test the test piece's torque, maximum torque, yield point torque, upper and lower yield point torques, torsional strength, and shear modulus. Torque and torsion angle are automatically tracked and displayed.Test curve, torque value, torsion angle, and torsion speed. After the test, the test data is automatically processed, and performance parameters such as the material's yield point and torsional strength can be automatically calculated. Report formats can be customized according to user requirements and printed.

Specific functions are as follows:

Automatic zeroing: Test torque and angle can be reset to zero at any time as needed;

Automatic Shift: Automatically switches to the appropriate range to ensure load measurement accuracy;

Automatic Calibration: Automatically calibrates the test force indication for accuracy;

The collected signals are automatically processed, displayed in real time, and stored. Upon completion of the test, the system automatically returns to the initial test state.

Failure determination: Automatically returns to the initial test state after the specimen breaks.

Synchronize all data, indicators, and curves during the test.

Set the test torque (Tau) to test the torsional angle (omega) of the material/component. Set the torsional angle (omega) to test the test torque (Tau) of the material/component.

Automatically determine if a sample is acceptable by setting upper and lower limits. Multiple test points can be set (including forward and reverse detection).

Deflection caused by the sensor can be compensated. This means that deformation caused by the sensor and overall machine stiffness does not affect angle accuracy.

Equipped with automatic overload shutdown, overcurrent, and overvoltage protection.
