What are the applications of cup burst testing machines

It is mainly used to test the plastic deformation performance of metal thin plates and strips. It uses oil cylinder clamping and cracks on the cylinder top sample, and has the function of automatic parking when cracks appear on the plate; it uses a microcomputer to control the entire test process, and dynamically displays the clamping load value, stamping load value, cup burst value, test speed and test curve in real time. It is a commonly used equipment for manufacturers of metal thin plates and strips, quality inspection units, steel research institutes and other units.

The spherical punch on the top is stamped against a sample clamped in the pad die and the pressing film to form a dent until a penetrating crack appears, and the depth of the dent measured by the displacement of the punch is the test result.
