Application: 
This machine is a special equipment for conducting ductility test on metal sheets and strips. It is also the only equipment to evaluate the plastic deformation properties of metal materials in China. The standard complies with the national standard GB4156-2007 "Metal Cupping Test Method" to test various metal sheets.
Using hydraulic clamping, hydraulic stamping compound cylinder; sample cracks stop automatically, easy to observe cracks; peak memory function, the maximum punch pressure, the maximum depth of automatic memory; punch and sample replacement, easy loading and unloading
The main features of this product are the precision of the cupping value is 0.01mm, the control accuracy of the main loading test force is 1N, the loading speed of the main test force is equal rate control, which greatly improves the control accuracy of the machine, and is loaded as electricity. Controlled mechanical loading, wheel-spoke sensor force measurement, improved test accuracy of the main test force and control of test piece breakage accuracy, selected a high-precision encoder to measure the cupping value, from the test accuracy, can guarantee the decimal point The accuracy of the last two digits. The test process is fully automated and automated.
