Description
Four Point Bending Tester
Main functions
This machine is suitable for widely used in tablet computer, mobile phone lens, glass and other products to do compression, bending test, using servo motor, ball screw, American original force value sensor; It is the ideal test equipment for related manufacturing enterprises, colleges and universities, scientific research units and technical supervision departments. Equipped with special test control software and clamping device, it can test the performance of the lens, and automatically calculate the maximum test force value (minimum force value/average value), breaking force value, tensile and compressive strength, elongation, peeling strength, peeling force and other parameters according to GB, JIS, ASTM, DM, ISO and other standards. The results are accurate, reliable and good repeatability. The data can be modified (GB8170), and the mechanical performance indexes such as Fm, Rm, Rp, ReH, ReL, Re, A, Z, E and load-deformation, stress-strain curves can be printed. Equipped with special three-point compression, four-point compression, anti-bending molds; It is the ideal equipment for enterprises and supervisory agencies to detect the difference products and the teaching and research of scientific research institutions.
Four Point Bending Tester
Control software introduction
Software operating system language: Simplified Chinese/English.
Force unit: N, KN, Kgf, Lbf, length unit: mm, cm, in can be freely converted
Automatic zero: When the computer receives the test start instruction, the measurement system will automatically zero;
Display mode: data and curves are dynamically displayed with the test process;
Result reproduction: the test results can be accessed arbitrarily, and the data curve can be re-analyzed;
Comparison of results: Multiple test characteristic curves can be superposed, reproduced, amplified and presented with a group of samples in different colors for analysis and comparison;
Emergency stop: emergency stop switch is provided for cutting off the power supply of the whole machine in emergency state;
Control mode: The computer software sets various control methods such as speed, load break (rupture), and running time Automatically determine material fracture, crushing, etc., and automatically stop, can be set automatic return
Curve type: Load-displacement, load-time, displacement-time. Stress-strain, strain-time, stress-time. The vertical and horizontal coordinates of the curve can be set arbitrarily.
Available test information: Maximum strength, minimum strength, fracture value, upper and lower yield strength, tensile strength, compressive strength, elastic modulus, elongation, maximum, minimum value of stripping interval, average value, etc. With overload, overcurrent, overvoltage, undervoltage, overspeed, stroke and other multiple protection. The data results are exported from the crystal report format currently accepted by the national standard.
