0-10KN digital tensile machine

ZY series digital electronic tensile machine (0-10kN)

The ZY series digital electronic tensile testing machine is an instrument used to test the mechanical properties of materials, such as tensile strength, peeling, tearing, and H-extraction. 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 transmission part adopts variable frequency speed regulation, which runs smoothly, has stable performance, and high precision.

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 frequency converter to change the stretching speed, and the speed value is directly read out. The motor drives the lower gripper (fixture) through V-belt worm screw transmission, thereby achieving the tensile change of the sample. 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 experimental measurement and control system is a measurement and control instrument designed specifically for electronic testing machines, integrating measurement and control. It can perform tests such as stretching, compression, bending, shearing, tearing, and peeling.

This system adopts 32-bit ARM technology, combined with 24 bit high-precision AD and large capacity memory, which has high measurement accuracy, fast and stable response, and fast and accurate control speed. And adopt a dot matrix graphic LCD display to display, save and print the test results in intuitive text and graphic form (optional micro thermal printer); The user operation adopts a multi-layer menu structure displayed in Chinese characters, which is powerful and easy to operate. It also adds fault-tolerant processing and automatic fault search and prompt functions, such as sensors, AD values, units, zero points, and calibration values; Gauge length, rated deformation, calibration value; And whether it automatically detects cracks, automatically returns to the starting point, and other parameters. Can calculate test parameters such as maximum force, yield force, average peel force, and maximum deformation. Can be connected to a PC and optionally equipped with upper computer software. Real time display of force displacement, force time, displacement time, stress-strain curves, automatic calculation of maximum force, yield force, average force, maximum deformation, yield point, elastic modulus and other parameters, and flexible report editing and printing functions.

The range of the sensor on this machine is 2500N (assumed), and the maximum force value of the material should be predicted during testing. It is strictly prohibited to use it beyond the range.
