Chongqing Academy of Science and Technology: microcomputer control electronic pressure testing machine
Equipment use:
This equipment is used for the transverse fracture strength test of cemented carbide in GB 3581-83 "Method for Determination of transverse fracture strength of Cemented carbide"。Other pressure or bending tests can also be performed with other fixtures。
504C microcomputer-controlled electronic pressure testing machine is a special equipment for the transverse fracture test of cemented carbide samples;Meet the requirements of the transverse fracture strength test of cemented carbide in GB 3581-83 "Method for determination of transverse fracture strength of Cemented carbide"。
The power source of the machine is a servo motor, which is decelerated by the 2-stage synchronous belt to drive the ball screw to rotate, and the bearing is driven by the ball screw nut to rise and fall, and the 3-point bending test is carried out on the cemented carbide sample。

3. Main feature
Pure electric, no hydraulic, low noise, no pollution;
The transmission system adopts efficient ball screw and synchronous tooth belt;
With auxiliary support, it is easier to push and drop the sample;
The control system adopts the special digital closed-loop control and measurement system DTC-350;
The whole test process is controlled by computer, and the test force value, deformation value, test speed and test curve are displayed dynamically in real time.
The data is processed and analyzed by computer, and the test results are saved automatically. After the test, the test curve can be retrieved again, and the test process can be reproduced by curve traversal, or the curve is compared and enlarged.
Full Chinese test software, with data and graphics processing functions, can print out a complete test curve and test report。
