Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

BJNZ-5000Nm microcomputer controlled full automatic material torsion test machine is used to test all kinds of metal and non-metal materials, such as automobile drive shaft, high strength bolt, oil field drill rod, coal drill rod and other metal and non-metal materials, and can obtain maximum torque, torsion strength, upper yield strength and lower yield strength and other performance parameters.

The drive shaft torsion tester is made and verified according to GB/T 10128 "torsion test method for metallic materials at room temperature" and JJG 269 "verification regulation for torsion testing machine". The main machine is composed of motor loading, transmission system, data acquisition, processing, control, display system and so on. It is mainly used for testing the torsion mechanical properties of materials and finished products at room temperature, and can also be used in the test of torsion failure of materials and finished products. The test specimen is installed between adjustable clamping fixtures to adapt to the test of torsion mechanical properties of different tested specimens. The transmission shaft torsion test machine adopts computer control operation. The software synchronously displays the curves of torque - time, twist angle - time, torque - twist angle, torque - angle and so on. The parameters such as angle, torque and torque peak are displayed in real time, and the test results can be stored and printed.

GB/T 10128 "torsion test method for metallic materials at room temperature"

JJG 269 "verification regulation of torsion test machine"

1, humanized Chinese Windows interface, menu display, simple operation.

2, automatic storage, experimental conditions, experimental data automatically save, can be adjusted at any time.

3. The experimental data and operation can be collected in real time.

4. The curve is traversing. The data of any point in the curve can be transferred according to need.

5, automatic analysis of the experimental results, calculate the upper yield strength, lower yield strength, maximum torque point and other material characteristics.

6, sampling inspection can be done for products, and batch tests can be carried out.

7. Record torque time, twist angle time, torque twist angle and torque angle test curve. It can switch over and observe at any time and sample at high speed.

8. The data of the transmission shaft torsion test machine is automatically saved. Print and print reports can be selected or compiled.
