Spring tension testing machine can also be called spring tension and compression testing machine. It can do both spring tension test and compression spring pressure test. The lower space of the machine can do pressure test and the upper space can do tension test. There are many specific details of the spring testing machine. Today, let's talk about its load accuracy and specific standards.

1、 Load accuracy

Selection of units within: kg / N / lb safety device: up and down stroke limiting device, automatic interruption point shutdown function. Explicit: WindowsXP test software + computer screen display. Power supply: AC220V 50Hz. Machine size: main engine 120 spring testing machine mechanical test bench weight: about 450 kg.

2、 Introduction to four standards of mechanics

1. Load displacement curve; Load and time curve; Displacement and time curve; Stress and strain curve.

2. According to the requirements of various countries for test pieces, edit the corresponding test standards, fill in the sample data, edit the test methods, and make them available for future testing.

3. Automatically store the test results and edit them as report printing output. With formula editing function, multiple tested curves can be compared.

4. The number of decimal places, physical quantity units and password protection can be set. Basic operation steps: power on, select the test project, set the test parameters, start the test standby state, clamp the test piece, start the test, automatically return to the bit after the test, send the test data, display the test results and curves, permanently store the test results, and output the test results and curves on demand.

Finally, the spring testing machine displays the whole process and curve of the mechanical test on the computer display, and the microcomputer automatically transmits the test settings and test data. Users can modify the test report and output the standard report according to their own requirements. Through the superposition analysis of group test curves, the quality control parameters can be accurately mastered. The multi-mode data query function can enable managers to clearly grasp the development and change trend of quality control.

Both the load accuracy of the spring testing machine and the four standards of its mechanics mentioned above are the most important aspects of the spring testing machine. Operators should master these two problems. Bihuan control software has two control modes: A. PID control regulation mode B. model Lake control regulation mode (the first in the industry). The whole test process can achieve constant force value control, constant displacement control, constant deformation control, low-frequency fatigue control and arbitrary program control.
