GBW-60B Computer Control Cupping Testing Machine

Cupping Testing Machine

GBW-60B cupping testing machine is a specialized equipment for conducting ductility tests on metal sheets and strip materials, and is currently the only equipment to evaluate the plastic deformation performance of metal materials. It complies with the national standard GB/T 4156 Metallic materials-Sheet and strip - Erichsen cupping test, and meets JJG583 Verification Regulations of Cupping Testing Machine
3.Main Characteristics
3.1. The Cup penetration Testing Machine adopts a new structural principle, can achieve constant control of speed rate. (In the past, the energy of fuel tank can not achieve constant control of speed rate, hydraulic sensor’s precision and accuracy performance is also lower).
3.2. Our company has produced a new type of cupping testing machine, has already transformed the past oil source into permanent servo electric motor speed loading; at the same time, the hydraulic sensor has been replaced by dyadic sensor, has greatly enhanced the precision and accuracy of the penetration value.
3.3. the cup protrusion measurement instrument for the import of high-precision grating displacement sensor, the indication error accuracy within ≤ ± 0.02mm , thus improving the controllability and accuracy of the machine.
3.4. both from the hardware configuration and force transmission principl, it has been greatly improved than the original machine, equip the computer control, to achieve the perfect machine , it can achieve the results of the report, storage, batch, curve Drawing and so on.Cupping measuring instruments measure the grating, resulting in improved aircraft controllable.
