Automatic Type Cupping Testing Machine

Model:GWB-60C

Description:

The digital cupping tester is mainly used in the test of metal sheets and thin strips. The automatic cupping testing machine can test the plastic deformation performance of the sheets and thin strips. The automatic cupping testing machine meets the requirement of international GB/T 4156-2007 "Metal Material Sheet and Thin Strip Erichsen Cupping Test”.
Adopting a hydraulic clamping and hydraulic stamping composite oil cylinder, the cupping tester automatically shuts down when a test sample has crack, so as to facilitate the observation of crack. With peak value memorizing function, the cupping tester can automatically memorize the maximal stamping force and the maximal deformation depth. A turning type clamp ensures the convenient replacement, assembling and disassembling of a punch and a test sample.
