1.The Main Function:
Applicable to mobile phone mirrors, flat materials, etc.; generally three-point bending is the main, but a small number of customers require four-point bending to test. Now let's distinguish the difference between three-point bending and four-point bending.
Generally, there are two kinds of loading stress modes, namely three-point bending and four-point bending. Different bending methods have different bending strengths. Both loading methods have advantages and disadvantages. The three-point bending loading mode is simple, and the loading mode is concentrated. The bending distribution is not uniform, the defects of a certain part may not be displayed, and the effect is not achieved. The bending moment is evenly distributed at the four-point bending, and the test result is more accurate, but the pressing structure is complicated and less used in industrial production.
Three-point bending definition: A test method for measuring the bending properties of materials. The strip sample is placed flat in the bending test fixture to form a simple supported beam. The distance between the two lower support points of the supporting specimen is adjustable depending on the length of the specimen, and there is only one loading point above the specimen.
Four-point bending definition: A test method for measuring the bending properties of materials. The strip sample is placed flat in the bending test fixture to form a simple supported beam. The distance between the two lower support points of the supporting specimen is adjustable according to the length of the specimen, and there are two symmetrical loading points above the specimen.
2.This machine can do curve categories: load-displacement, load-time, displacement-time, stress-strain, strain-time, stress-time.
The curve vertical and horizontal coordinates can be set arbitrarily.
Test data available:
Maximum force, minimum force, fracture value, upper and lower yield strength, tensile strength, compressive strength, elastic modulus, elongation, maximum, minimum, and average peeling interval. (Customers need to order before ordering) With multiple protections such as overload, overcurrent, overvoltage, undervoltage, overspeed, and stroke.
This machine uses PC for data processing and analysis. The test results can be automatically saved. After the test, the test curve can be recalled. The curve can be traversed to reproduce the test process, or the curve can be compared and the curve can be enlarged. The complete test report can be printed out instantly. Test curve.
The data results are exported from the current national standard crystal report format.
