1. Structural features and uses
The host adopts cantilever type (also called single arm type), microcomputer control, full Chinese operation platform, man-machine dialogue mode, computer screen displays test force, spring deformation, stiffness curve, test machine working status, loading speed, etc. Kind of data processing function. Imported CNC speed-regulating motor is loaded with precision rolling screw drive, which can perform stress analysis on the spring.
2. Control method
1. Set the test force P to detect the remaining height H or deformation F of the spring;
2. Set the remaining height H or deformation F of the spring, and check the test force P;
3. Set the pre-compression times of the spring and perform pre-compression;
4. With intelligent programming function;
5. With overload, overvoltage, overcurrent, limit position protection and other functions.
