BT-60 Manual Cupping testing machine
Usage
Cupping testing machine, designed according to GB/T 4156-2007, is used to evaluate the resistance of metal materials to the anti-cracking or anti-separation of metal substrates after being subjected to the indentation test under the standard test method; Two-way composite cylinder for measuring metal stretchability. It uses a sphere with a diameter of 20 mm. The steel ball is topped at a certain speed, and the surface of the test plate is observed through the observation hole. Stop immediately when the test plate is deformed and the first crack is observed.
Main technical parameters
1, Punch diameter: Φ20 mm
2, Punch maximum stroke: 60mm
3, Clamping piston stroke: 30mm
4, The maximum load: 60KN
5, Test plate size: 120 mm * 120mm * δ = 0.30-3 mm flat non-deformed steel sheet
