Introduction: The cupping tester is mainly used for the test of the process performance of thin metal plates and thin strips, and tests the plastic deformation properties of thin plates and thin strips. Satisfy the requirements of the national standard GB/T 4156-2007 Metallic Sheets and Thin Strips Erickson Cupping Test. Hydraulic clamping, hydraulic stamping compound cylinder; sample cracks stop automatically, easy to observe cracks; peak memory function, the maximum punch pressure, maximum depth of automatic memory; flip-type fixture, punch and sample replacement, loading and unloading Convenience. Technical Parameters: Specification Model: GBW-60Z Testable steel plate thickness: Standard cupping test 0.1-2mm, (non-standard cupping test: 0.1-3mm) The maximum width of the plate: 100mm Punch maximum stroke: 60mm Clamping piston stroke: 19-21 mm Maximum cup load: 60kN Maximum clamping load: 25kN Mould specification: Standard punch diameter: Φ20±0.05mm, standard pad die diameter: Φ33±0.1mm Standard die aperture: Φ27±0.05mm;(non-standard) Digital display resolution: 0.01mm Digital display mode: PC screen display Display contents: Clamping force, punching force, displacement and cupping value, rate, draw-displacement curve Control method: Computer automatically implements the test process Structural features: Composite cylinder, dual oil pump, grating scale measurement
