How to choose Electronic tensile machine Methods
Test speed of electronic tensile machine. Some of them are in the range of 10 ~ 500 mm / min and some are between 0.01 ~ 500 mm / min. the former generally uses ordinary speed control system, which has low cost and rough influence on precision. The latter uses servo system, which is expensive and has high precision. For flexible packaging enterprises, it is enough to select servo system with the speed range of 1 ~ 500mm / min, which does not affect the accuracy and the price is within the reasonable range.
The main mechanical configuration and machining precision transmission are screw drive and rack drive. The former is expensive, used for high precision and high repeatability; The latter is cheap, low precision and low repeatability. Flexible packaging tension machine is frequently used and requires high precision, so lead screw drive should be selected. The lead screw plays a decisive role in the measurement of tension accuracy. Generally, there are ball screw, trapezoid screw and general screw. Among them, ball screw has high degree, but its performance depends on the operation of computer servo system, and the whole set of price is relatively expensive. The main cost of the sensor lies in its service life. Photoelectric induction is one of the more advanced technologies, which can be used more than 100000 times. Machining accuracy: in terms of the machining process of the tension machine, there are turning, grinding, planing and washing processes; Have numerical control technology; Wire cutting technology; The choice of processing technology will directly affect the performance and price. Precision problems include force measurement accuracy, velocity accuracy, deformation accuracy and displacement accuracy. In addition, the force resolution is almost 1 / 100000. The service life of the tension machine is generally more than five years for flexible packaging. In the face of a thousand yuan low-cost tension machine, is the after-sales service timely in place? It is worth pondering.
Shop Electronic tensile machine It should be fully considered whether the unit is professional and has a complete after-sales service system. The tension range of 300 n is enough; According to the performance and requirements of the flexible packaging film to be tested, the stroke is 600-800mm; Intelligent three basic configuration: host, computer, and printer, if the microcomputer function is strong, can print directly. It can also be equipped with ordinary computer. If equipped with a computer, the manufacturer should add the corresponding control system. With the help of computers, complex data analysis can be carried out, such as data editing, local enlargement, report form adjustment, and group statistical analysis. Flexible packaging requires a multi-purpose tensile machine, Electronic tensile machine On the basis of different fixtures, tensile, compression, bending, tearing, shearing, 180 degree stripping and 90 degree stripping tests can be carried out.
