The working principle and specific structure of the electronic tension machine

The electronic tensile testing machine consists of one or two vertical support columns and It consists of one Liquid crystal screen, the bearing column is installed on a fixed horizontal base, and the top is a movable horizontal bar. In most current electronic traction machines, the column is generally driven by a screw to determine the position of the movable beam. IkETextile Testing Instruments, Testing Equipment Manufacturer

The specifications of the electronic tensile testing machine are determined by the load capacity of the frame The combination of maximum load and maximum load of the supporting unit is specified. The loading unit is mounted on a moving beam powered by an electric motor or oil pressure. An indicated on the deviceA right load cell measures force, which can be read from a digital display or computer. Many electronic tensile testing machines have interchangeable sensors that match the material being tested. IkETextile Testing Instruments, Testing Equipment Manufacturer

To induce stress in plastic, electronic Tension The machine exerts an appropriate force on the stencil. Specific tensile, flexure, compression, or shear tests are classified according to the direction of the strain induced in the specimen and the rate at which the force is applied. The basic test is carried out with a commercially available electromechanical electronic tensile testing machine. They are typically loaded in the speed range of 0.1mm/min to 500mm/min and different materials require different test speeds. Dynamic and cyclic tests such as break waxTum and fatigue are typically performed on a servo-hydraulic electronic traction machine with low loads over a long period of time.

Electronic tensile testing machine is the most common test for plastic are tensile strength and modulus, flexural strength and modulus. For tensile tests according to ASTM D638 and ISO527, both ends of the specimen are clamped. One handle is fixed and the other is in the crosshead, with the sample moving away from the fixed handles, the sample is pulled until it breaks, after which the crosshead automatically stops.

Place the bend test sample on the two supports on the fixed base the testing machine. For this test, the beam's direction of motion is opposite to that of the tensile test, wherethe unsupported center of the specimen is pushed rather than pulled until it bends and may break. In China, since many thermoplastics do not break in this test, according to the standard The test method must calculate the bending stress when the deflection is 1.5 times of thickness, and the most commonly used is the 6mm bending deflection for a 4mm thick sample.IkETextile Testing Instruments, Testing Equipment Manufacturer

How the sample stays on the bottom of the instrument is important as different types of tests require different fixtures. Changing mounts is not only difficult to maintain consistency of position (this often affects the test results), and it is easy to damage the sensitive part of the sensor, which is also a test of the experimenter's strength, and many women find it difficult to accomplish this task. In addition, the price isof the device several hundred yuan, and the oil pressure-operated device is the most expensive 1000 yuan. Therefore, try to change the device as little as possible. Some electronic tensile testing machines and universal material testing machines are designed together with three-point bending devices and pulling devices, which makes the process of changing devices.IkETextile Testing Instruments, Testing Equipment Manufacturer
