Do you know how important the configuration of the universal tensile test machine is? The configuration of the universal tensile test machine

The lead screw of the universal tensile testing machine plays a decisive role in the measurement of tension accuracy. Usually, there are ball screws, trapezoidal screws and ordinary screws. Among them, the ball screw has a high degree, but its performance depends on the operation of the computer servo system.

The accuracy required for flexible packaging can be achieved by using ordinary lead screws and trapezoidal lead screws, i.e., the accuracy is 0.5-1%. The transmission includes gear transmission and chain transmission. The former is expensive and is used for high precision. The main cost of the sensor lies in its service life. Photoelectric sensing is one of the more advanced technologies and can usually be used more than 100,000 times. Of course, these are just the basic maintenance methods of mainstream tensile machines (tension testing machines).

During the test stroke problem during the maintenance of the universal tensile tester, the stroke can be 600-800mm according to the performance and requirements of the flexible packaging film to be tested. If the material elongation exceeds 1000%, the stroke 1000 or 1200mm can be selected. The tensile machine will output the results during maintenance, and the test results can be set arbitrarily: high strength, elongation, tensile strength, constant elongation, constant elongation 8 long force values, yield strength, elastic modulus and large test force. It can be said that this is the result output when the microcomputer is running.
