Introduction to the configuration and test speed of tensile testing machine

Tension testerMain configuration:

The transmission has lead screw transmission and rack transmission. The former is expensive, used for high accuracy and has high repeatability for tests; the latter is cheap, used for low accuracy and has low repeatability for tests.

The lead screw has a decisive effect on the measurement of tension accuracy. Generally, there are ball screws, trapezoidal screws, and general screws. Among them, the accuracy of the ball screw, but its performance can only be achieved by operating the computer servo system, and the whole set is also relatively expensive. The use of general lead screws and trapezoidal lead screws can achieve the accuracy required for flexible packaging, that is, 0.5-1% accuracy.

Drives, with geared and chain drives, the former is expensive for high precision; the latter is cheap for low precision.

Tension testerThe main cost of sensors lies in their lifespan. Photoelectric induction is the relatively advanced technology, which is generally available for more than 100,000 times, and can be achieved by import and some domestic joint venture manufacturers.

Test speed:

The national standard stipulates that the test speed is 200mm/min. Some of the market equipment are 10~500mm/min, and some are 0.01~500mm/min. The former generally uses ordinary speed control systems, which are relatively low in cost and rough affects accuracy; the latter uses servo systems, which are expensive and have high accuracy. For flexible packaging companies, it is enough to choose a servo system, which is 1~500mm/min. This does not affect the accuracy, and the price is within a reasonable range.
