Usage:

The cupping testing machine is used to test extend and stretch capacity of metal thin plate and band. It is the only instrument to test the metal’s plastic deformation. Also it can be used to test non-ferrous metal’s anisotropic character if adding impact cup mould. The machine adopts closed loop control and constant speed loading, so the test procedure can realize variable speed.

Parameter:

Max testing force: 60kN�?br /> Testing force range: 0.2kN�?0kN�?br /> Accuracy of test: ±1％；
Testing speed: 2�?00mm/min (at any speed constantly speed control)
Puncher cupping mould: φ20±0.05�?br /> Thickness of sample holding: 0.05�?mm (with high precision sensor, it can achieve ultrathin plate test. Special order: non-standard cup:0.05~3mm; non-ferrous metal plate:0.1~2mm)
Distance of puncher moving: 40mm�?
Distance of holding pistons running:40mm�?br /> Max load of punching: 60kN
Max load of holding: 10kN
Resolution of Erichsen value: 0.01mm�?br /> Hydraulic oil: N46 hydraulic oil

Special order: :

�?non-standard cupping puncher ball diameter:φ3±0.02、�?±0.02、�?5±0.05mm and full set moulds;
②standard punching cup nonferrous metal plate:0.1�?mm and non-standard punching cup nonferrous metal plate 0.1�?mm and full set moulds;
③Cupping testing machine according with American and Europe standard.
