Microcomputer controlled Cupping Testing Machine
Ⅰ. Features
This machine is a special equipment for the ductility test of metal sheets and strips, and it is also the only equipment for evaluating the plastic deformation properties of metal materials in China, to test the anisotropy of various metal sheets.
It adopts hydraulic clamping and hydraulic stamping compound oil cylinder; the sample will automatically stop when cracks occur, and it is easy to observe the crack; it has a peak value memory function, that is, the maximum punching force and maximum deformation depth are automatically memorized; the punch and sample are replaced, and the loading and unloading is convenient.
The main features of this product are that the accuracy of the cupping value is 0.01mm, the control and measurement accuracy of the main load test force is 1N, and the loading speed of the main test force is controlled at a constant rate, thus greatly improving the control accuracy of the machine. Controlled mechanical loading, wheel-spoke sensor force measurement, which improves the test accuracy of the main test force and the rupture accuracy of the control sample.
A high-precision encoder is used to measure the cupping value. In terms of test accuracy, the decimal point can be guaranteed. The accuracy of the last two digits. The test process is automatically controlled by computer and analyzed automatically.

Principle
This International Standard specifies a method fordetermining the ear height of metal sheet and stripof nominal thickness from 0,1 mm to 3 mm after deep drawing.
It is a test that uses a cylindrical punch to press the clamped metal sheet or strip sample into a specified die to form a cylindrical cup to show the anisotropy of the material expressed by the ear-making rate.
