Digital display semi-automatic cupping testing machine
1.Introduction
The cupping testing machine is specially used to test extensibility of metal thin sheet and banded material and is the only instrument to test the metal ’ s plastic deformation.The compound oil cylinder adopt hydraulic clamping, hydraulic press. Automatically parking when cracking appearing , easy to observe crack; Have the function of remember the peak--the maximum pressure, maximum deformation flaring depth. Tilting fixtures, the punch and sample replacement, loading and unloading convenient Type GBS-60B for digital display semi-automatic Cupping Testing Machine, manual adjust the test rate, adopt grating measure the displacement. Single-chip computer record, operational data and judge the park.
