Sponge tensile testing machine

ZYSeries Sponge Tensile Testing Machine（0-500N）

ZY-The 500N sponge tensile testing machine is used to test the tensile, peeling, and tearing properties of materialsHExtract instruments with equivalent mechanical properties. Widely used in industries such as rubber, plastic, textile, chemical, steel wire, rubber hose, wire and cable, plastic, pipe, etc., it is a high-precision, economical and practical instrument.

The tensile machine consists of a host, a speed control system, data acquisition and processing, sensors, and electrical interlocking. The host includes the body, transmission mechanism, and measurement system. Data processing is handled by a microcomputer processor. This machine uses a stepper speed controller to change the stretching speed, and the speed value is directly read out. The motor passes throughVbeltThe worm screw transmission moves the lower gripper (fixture) to achieve the tensile change of the specimen. The host head is equipped with a tension sensor, with its upper end connected to the connecting plate of the top crossbeam of the host and its lower end connected to the upper clamp. The sensor is only subjected to vertical tension and is not affected by torsion or direction finding force to ensure force measurement accuracy. The sample is clamped between the upper and lower clamps, and during the test process, the force on the sample is converted into an electrical signal by the force sensor and input into the microcomputer acquisition and control system. After the experiment is completed, it will be automatically processed, calculated, and the results will be displayed.

This touch LCD measurement and control system adopts 32-bit ARM technology and DSP high-performance processor control technology, and the display part adopts a 7-inch 65K color ultra clear touch screen with a resolution of 1024 * 768. The software includes startup animation, main screen display, large curve display, unit setting, selection and result calculation display of multiple test standards, device status display, hardware parameter setting, device calibration, PID parameter setting, customized parameter editing, sample scheme editing, sample size editing, visual printing and other functions. The micro printer supports multiple models to choose from, and the motor control supports free switching of servo, stepper, frequency conversion, DC and other control methods (no need to replace the system at the factory, standard functions).

This experimental measurement and control system is a high-performance measurement and control instrument designed specifically for electronic testing machines, which integrates measurement and control. It can perform tests such as tension, compression, bending, shear, tearing, and peeling. The software can complete the calculation and real-time display of parameters such as maximum force, maximum deformation, tensile strength, elongation at break, total elongation at maximum force, yield point elongation, post fracture elongation, upper and lower yield strengths, elastic modulus, yield point force, elongation at break, yield point elongation, tensile strength at break, tensile stress at yield point, tensile stress at constant tension, and elongation at constant tension (according to the user specified force level). Among them, the horizontal values of tensile strength and tensile strength can be input into the relevant positions of the software on the sample parameter interface according to the actual requirements of the customer's use. The parameters that can be calculated also include compressive strength, upper and lower compressive yield strength, compressive modulus of elasticity, flexural strength, flexural modulus of elasticity, average bending force, average peel force, peel strength, maximum peel force, minimum peel force, tear strength, average shear force, shear strength, shear modulus and other mechanical and physical properties related parameters.

Real time display of data

The system can display simultaneouslyFour channels of data, namely force value, displacement, deformation, and velocity, are automatically collected and refreshed after the touch screen is powered on. Force resolution of 1/250000, accuracy of 0.2% or above, range of 1-9999999KN arbitrary; Displacement sensors and deformation sensors have a resolution of up to 1umResponse frequency40kHz, range 0-10000mmAny setting, the precision instrument system has no errors,4-phase decoding type;

Real time switching of units

Switching of Force Units（N、KN、g、kg、gf、kgf、Ib、Ibf、oz、ozf）, The unit switching between deformation and displacement (mm, cm, m, in) is completed on the "Sample Parameters" page. After the switching is completed, the numerical and result display data on the main interface are automatically converted.

Calculation of experimental results

According to different calculation methods, the display content of the test result list automatically switches. After selecting the calculation method, the next time the power is turned on, the last selected calculation method will be automatically defaulted for the test.

Real time display of curves

The system provides a convenient small curve interface display on the main interfaceThere are two ways to display the "Single Graph" large curve interface. In standby mode, click "Single Graph" and the system will display the large curve interface. Click "Return to Home" and the system will automatically switch back to the monitoring main page. The coordinate axis range of the two curves can be freely set according to needs.

Test control button

The touch screen system provides a set of touch screen control buttons for experimental control.

[Operation]After the equipment is ready, it is allowed to start running the test (if there is an abnormal prompt on the equipment, clickAfter "running", the system will sound an alarm for abnormal operation, and users can follow the prompts to complete the operation;

[Stop]Stop the experiment or stop the control command for the movement of the crossbeam;

Reset to zeroClear all sensor data (reset is invalid when the crossbeam is moving, the test is running, or the force sensor is abnormal, and the system will sound an alarm for abnormal operation. Users can follow the prompts to complete the reset operation);

【UP Move UpManually gradually control the upward movement of the crossbeamWith each click, the movement speed will continuously increase in the same direction, and the movement speed can be modified as needed in the "Custom Parameters" (when the crossbeam is moving in reverse, during experimental operation, under upper limit protection, or when the force sensor is abnormal, the upward movement is invalid, and the system will sound an alarm for abnormal operation. Users can follow the prompts to complete the upward movement operation);

【Down DownManually gradually control the downward movement of the crossbeamWith each click, the movement speed will continuously increase in the same direction, and the movement speed can be modified as needed in the "Custom Parameters" (when the crossbeam is moving in reverse, during experimental operation, under lower limit protection, or when the force sensor is abnormal, the downward movement is invalid, and the system will sound an alarm for abnormal operation. Users can follow the prompts to complete the downward movement operation);

【Force value returns to zero】When in standby mode, manual unloading is usually used to automatically release the applied load when there is an abnormal stop or sensor force failure during the test. After the load returns to zero, the crossbeam automatically stops and can be manually stopped and unloaded midway.

Test status and abnormal information
