We know, tensile tester by the measurement system, drive system, control system structure of the three is also essential as a high-precision machine.
　　A lot of development and design of these year Zhengbang testing equipment tensile tester machine, accompany clients to walk through a lot of thought, and the tensile tester is the product of the combination of modern electronic technology and mechanical drive technology, electromechanical give full play to their strong points constitute a large precision test instruments, a variety of materials tensile, compression, flexural, peel, shear, and a number of performance tests, and a wide measuring range, high precision, fast response characteristics.Reliable, high efficiency, real-time display of recording, printing of test data.
　　We take a look at the control system of the tensile tester, as the name suggests it is to control the operation of the system of the testing machine to test the operation of the machine can be controlled through the console display can be informed of the status of the testing machine and test parameters, if the aircraft various functions with computer, can also be achieved by computer and data processing and analysis, test results printing.Communication between the testing machine and the computer are generally using the RS232 serial communication, which communicate through the computer behind the serial (COM port), this technology is relatively mature, reliable, easy to use.
　　Again, we need to carefully study the tensile tester under the measurement system, it is by the measurement of the force value, the deformation of the measurement and the measurement of the beam displacement.The force values ??measured by a force measuring sensor, amplifier and data processing systems to achieve the measurement, the force measuring sensor is the most commonly used strain gage transducers.The deformation is measured by the deformation measuring means to measure, which is used to measure the deformation produced by the sample during the test.The apparatus has two chuck, the axis of rotation through a series of transmission mechanism and mounted on the top of the measuring device, the photoelectric encoder "together, when the distance is changed between the two chuck, driving the photoelectric encoder, the photoelectric The encoder will have a pulse signal output.This signal by the processor for processing, the amount of deformation of the sample can be drawn.Crosshead measurement principles with deformation measurement roughly the same amount of displacement of the beams are obtained by measuring the optical encoder output pulse.
　　The drive system of the final tensile tester for testing machine crosshead, its works by the servo system to control the motor, the motor after a the gearbox series of transmission mechanism to drive the screw rotation, so as to achieve the purpose of the control beams moving.Can be changed by changing the speed of the motor, the moving speed of the beams.
　　The Masakuni pull tester is used to test a variety of materials, semi-finished and finished tensile strength, compressive strength, and elongation do peel, tear, bending, bending, compression test, suitable for metal, plastic, rubber, textiles, synthetic chemicals, wire and cable, leather and other industries use.Design standards: ASTM D903, GB/T16491, GB/T1040, GB/T8808, GB13022, GB / T 2790/2791/2792, CNS-11888, JIS K6854, PSTC-7, PC display (can display and print the number of trials test value, maximum value, breaking value), welcome to order!
