Operation steps of bending tester

1. Turn the lever of the bending mechanism to the limit of the left hand side (opposite to the black knob). This action releases the cylindrical tank. Place the required cylinder in the groove, insert the test piece vertically between the cylinder and the pressure roller shaft (the coating faces the bending column), and push it between the clamping device at the lower end. The clamping unit can be adjusted, but during this period, the clamping device should not be fully locked. Pull the black knob, slide the inserted test piece with the clamping unit through the guide roller, so that its position is facing the circular shaft. Then fully lock the black knob to ensure that the clamping unit and test plate are fixed in this position.
2. Turn the screw on the bending rod, the pressure roller will act on the test piece, and the circular shaft will be below. Turn the bending rod until it reaches the limit position on the right side of the instrument. This motion will cause the test piece to bend around the selected circular axis.
3. The bending process should be carried out in a smooth motion, with a time of 1-2 seconds.
function
1. Automatic reset: the measuring system will automatically reset when the computer receives the test start command.
2. Automatic return: after the automatic identification test fracture, the movable beam automatically returns to the initial position at high speed.
3. Automatic storage: the test data and test conditions are automatically saved to avoid data loss caused by sudden power failure and forgetting to save.
4. Test process: the test process, measurement, display and analysis are all completed by the computer.
5. Display mode: data and curves are displayed dynamically with the test process.
6. Result reproduction: The test results can be accessed at will and the data curve can be reanalyzed.
7. Curve traversal: after the test is completed, you can use the mouse to find the force value and deformation data of the test curve point by point, which is convenient and practical for obtaining the test data of various materials.
8. Comparison of results: multiple test characteristic curves can be superimposed, reproduced, amplified and presented with different colors for analysis and comparison of a group of samples;
9. Curve selection: stress-strain, force-time, strength-time and other curves can be selected as required for display and printing;
10. Batch test: the test of a batch of samples can be completed in sequence after the test with the same parameters is set at one time;
11. Test report: (according to customer needs)
Tensile: maximum force, tensile strength, elongation at break, elastic modulus, etc.
Bending: maximum force, bending strength, deflection, elastic modulus, etc.
Compression: maximum force, compression strength, yield strength, modulus of elasticity, etc. The test report can also be programmed and printed according to the format required by users;
12. Limit protection: it has two levels of protection: program control and mechanical protection;
13. Overload protection: automatic shutdown when the load exceeds 10% of the rated value;
Emergency stop: emergency stop switch is set to cut off the power supply of the whole machine in emergency;
Automatic diagnosis: the system has the automatic diagnosis function, and regularly checks the measuring system and drive system for overvoltage, overcurrent and overheating, and stops immediately in case of abnormal conditions;
14. Realize the independent operation of host and computer;
