4. Key description:

1. Host: The machine adopts a gantry floor-standing double-space structure, which can be pulled up and pressed down, and the beam can be raised and lowered to adjust the speed steplessly. The transmission system is composed of a low-noise arc synchronous tooth belt deceleration system and a ball screw pair, with stable operation, high efficiency, low noise and no pollution.

2 attachments:

Standard configuration: a pair of lever-type stretching attachments and compression attachments. The stretching attachment adopts a manual clamping method, which is convenient, reliable, and non-slip. During the clamping process, the jaws do not move, and the clamp body moves up and down. The sample is not subject to additional force, which ensures the accuracy of the test results.

5. Function Introduction

a) This machine adopts a built-in controller, which ensures that the testing machine can realize constant velocity displacement control.

b) Using stepping or AC servo motor, the performance is stable and reliable, with over-current, over-voltage, over-speed, overload and other protection devices. The speed ratio can reach 1:10000.

c) The electrical control circuit refers to the international standard, conforms to the national testing machine electrical standard, and has strong anti-interference ability, which ensures the stability of the controller and the accuracy of the experimental data.

d) Automatic shifting: automatically switch to the appropriate range according to the load to ensure the accuracy of the measurement data; realize the automatic shifting, zeroing, calibration and automatic shifting of physical zeroing, gain adjustment and test force measurement in the true sense Save to disk, without any analog adjustment link, the control circuit is highly integrated

e) Condition storage: test control data and sample conditions can be made into modules, which facilitates batch tests;

f) Automatic speed change: during the test, the speed of the moving beam can be changed automatically according to the preset program or manually;

g) Automatic calibration: the system can automatically calibrate the accuracy of the indication;

h) Automatic saving: after the test is over, the test data and curves are automatically saved;

i) Process realization: the test process, measurement, display and analysis are all completed by the computer;

j) Batch test: For samples with the same parameters, it can be completed sequentially after one setting;

k) Test software: Chinese WINDOWS interface, menu prompts, mouse operation;

l) Display mode: data and curves are dynamically displayed along with the test process;

m) Curve traversal: after the test is completed, the curve can be re-analyzed, and the test data corresponding to any point on the curve can be found with the mouse;

n) Curve selection: Curves such as stress-strain, force-displacement, force-time, displacement-time can be selected for display and printing as required;

q) Test report: The report can be compiled and printed according to the format required by the user; it has a network interface, which can carry out data transmission, storage, printing records and network transmission printing, and can be connected to the internal LAN or Internet of the enterprise.

r) Limit protection: with program-controlled and mechanical two-level limit protection;

s) Automatic stop: After the sample breaks, the moving beam stops automatically;

t) Overload protection: when the load exceeds 3-5% of the maximum value of each gear, it will automatically stop;

Two modes of automatic and manual are used to obtain the test results, and the report form is automatically formed, which makes the data analysis process simple.
