1, the cupping test machine uses a new type of structure principle, constant speed servo motor load, constant speed control can be achieved by a computer-controlled process stamping, punching speed can be stepless adjustment set in advance. (Past cylinder oil source Afterburner can not achieve a constant rate control).
2, the clamping force is independent of load by the hydraulic oil source, the clamping force can be adjusted, data synchronization display, independent calibration.
3, measuring devices have changed in the past hydraulic sensors spoke Sensors, Erichsen value measurement encoder measuring, testing process using low friction punch move my company's first mobile device, combined with high-precision sensors spokes (direct load ) enables test (0.05 ~ 3mm) thin sheet, while greatly improving the accuracy and reliability of the test machine measured cupping value. perfect match of the instrument measuring device and loading device and its control program, a very good It solves the problem of poor reproducibility of test data, but also the introduction of new machines Erichsen cupping verification procedures and test methods to provide a reliable basis for our country.
4, cupping die easy to replace, easy sample handling, sample into the post, press the Auto button to complete clamping, test parameters can be entered, changed, stamping process to achieve closed-loop control, punch pressure drop judgment sample cracks automatic parking, while being easy to observe specimens crack test data computer displays, and a peak memory function, ie, the maximum punch pressure, Erichsen value, etc., to achieve test results report, storage, batch, draw the curve, deformation height automatically memory , one end of the trial can be automatically restored to the state to be tested.
