Suzhou tensile testing machineIt is a mechanical force testing machine used to test the mechanical properties of materials such as tension, compression, bending, shearing, and peeling. After gradual improvement, it has now developed into a variety of physical and mechanical performance tests suitable for plastic sheets, pipes, profiles, plastic films and rubber, wires and cables, waterproof rolls, metal wires, and other materials.
Measurement System of Suzhou Tensile Testing Machine
The measurement system of the tensile testing machine consists of force measurement, deformation measurement, and beam displacement measurement.
Measurement of force value: Measurement is achieved through force sensors, amplifiers, and data processing systems. The most commonly used force sensor is strain gauge sensors.
Measurement of deformation: measured by a deformation measuring device, which is used to measure the deformation of the specimen during the testing process. There are two clamps on the device, which are connected to the photoelectric encoder installed on the top of the measuring device through a series of transmission mechanisms. When the distance between the two clamps changes, it drives the shaft of the photoelectric encoder to rotate, and the photoelectric encoder will output a pulse signal. By processing this signal with the processor, the deformation of the sample can be obtained.
Measurement of beam displacement: Its principle is roughly the same as deformation measurement, both of which obtain the displacement of the beam by measuring the output pulse number of the photoelectric encoder.
The Drive System of Suzhou Tensile Testing Machine
The driving system of the tensile testing machine is mainly used for the movement of the crossbeam of the testing machine. Its working principle is controlled by a servo system to control the motor, which drives the screw to rotate through a series of transmission mechanisms such as a gearbox, thus achieving the purpose of controlling the movement of the crossbeam. By changing the speed of the motor, the movement speed of the crossbeam can be altered.
Control system of tensile testing machine
The control system of Suzhou tensile testing machine is the system that controls the operation of the testing machine. People can control the operation of the testing machine through the console, and the status and various test parameters of the testing machine can be obtained through the display screen. If the machine is equipped with a computer, it can also achieve various functions and perform data processing and analysis, as well as print the test results. The communication between the testing machine and the computer is generally done using RS232 serial communication, which communicates through the serial port (COM port) behind the computer. This technology is relatively mature, reliable, and easy to use.
There are many things to pay attention to when purchasing a tensile testing machine in Suzhou, and overall, the following aspects should be noted:
*Firstly, the range of material tensile strength that needs to be tested should be considered
The second issue is the test itinerary. According to the performance and requirements of the flexible packaging film, a stroke of 600-800mm is sufficient. Materials with elongation exceeding 1000% can be selected with a stroke of 1000 or 1200mm.
The third issue is the standard configuration problem: the three basic configurations of intelligence: host, microcomputer, and printer. If the microcomputer has strong functions, it can directly print. Additionally, it can also be equipped with a regular computer. With a computer, complex data analysis can be performed, such as data editing, local zooming, adjustable report formats, and statistical analysis in grouped styles.
The fourth one is the output result: the test result output result can be set arbitrarily: maximum force value, elongation, tensile strength, constant elongation, constant elongation value, yield strength, elastic modulus, maximum test force 8 items. This can be said to be the most comprehensive result output when operated by a microcomputer.
