GBS-60B Erichsen Cupping Tester
The GBS-60B is suitable for processing test for metal plate and belt material. It can inspect the anisotropism of nonferrous metal plate and the plastic deformation performance of metal plate and belt material.
Cupping test basics: The system uses a steel ball or ball punch of a certain specification to press a specimen, which is clamped with a 10 KN force. The force is applied until the specimen is penetrated. The depth that ball punch penetrates into the specimen is the cupping value of the tested specimen, and this cupping value is used to estimate the plastic deformation performance of the material.
Deep drawing cups testing of non-ferrous metals: This method uses a column punch of a certain specification to impact a round plate with a certain external diameter between clamping mould and cups testing mould. The round plate extends along the radial direction and bends under the pressure of the punch, which turns the plate to a column cup, then two symmetrical ear shape protuberances, are formed on the edge of this cup, the anisotropism of material is estimated by measuring the ear rate.

Torsion Tester
This testing machine uses a computer controlled AC servo system and is loaded through the active clamping head driven by the AC servo motor and cycloid pinwheel reduction motor. The torque and torsion angle are measured with high-precision torque transducer and photoelectric encoder. Computer will dynamically display the test torsion curve, loading speed, peak value, and so on. It is mainly used for the torsion test of metal and non-metal materials, as well as the torsion test for parts and components. It is an essential instrument to measure torsion properties of materials for mechanics laboratories of aviation industry, construction industry, scientific research dept, universities and industrial enterprises etc.
Main Functions and Features:
·Loading mode: imported AC servomotor and driver
·Testing of torque and torsion angle: high-precision symmetrical torque transducer for torque testing and high-precision LEC model photoelectric encoder for angle testing;
·Control mode: manual control and computer control;
·WINDOWS-based supervision software used to calculate mechanical indexes of materials. Automatic test data processing, dynamic display of test curves, storage and print out of test results. Operator can intervene in the analysis process and thus to improve the analysis accuracy.
