Erichsen Cupping Test For Sheet Metal

To punch out round disks from sheet metal strip and then use it to shape it with a drawing.

Erichsen cupping test for sheet metal.

The sheet holder force of e g. Based on the standardized erichsen cupping test a load cell and a high resolution distance measuring system have been integrated into a specially developed tool. Erichsen cupping test standards. Erichsen cupping test for sheet metal includes placing the metal sheet in the machine and punching a cup into the sheet until a crack appears.

Remove a piece of sheet metal. There are two most commonly used erichsen cupping test standards. Then the depth of the cup is measured and eventually ductility is measure as a function of this depth. In this test a punching force is applied to the metal sheet of thickness from 0 2mm to 2mm.

The cupping test for metal sheet thickness range is 0 1mm 5mm max. The forming process used for this test essentially records the stretching capacity of the metal material directly comparable with a stretch forming and bulge removal. Erichsen cupping testing machines the cupping testing machine is a sheet strip metal testing machine for ferrous and non ferrous metals with manual readout for cupping deep drawing deep draw bore expanding tests in accordance to corresponding national and international standards. Sheet metal testing machine model 100.

10 kn in accordance with din en iso 20482 is adjusted using a special regulating valve and the. Erichsen was the development of a special tool for deep drawing cup test in 1932. Punching capacity is 600kn and the pre tightening clamping device is with hydraulic servo loading pump for 600kn capacity. Using intelligent self learning evaluation software it is possible to make a statement on the suitability of the sheet metal within a few minutes.

Cupping test is a significant test to assess the ductile properties of the metal. A visual inspection is done to see if the test material has developed any cracks or deformity. It is very simple. Sheet metal testing machine with erichsen cupping up to 1 5 mm at 400 n mm2.

The erichsen olsen cupping test is used to determine the ductility of metal sheets and strips and meets the din en iso 20482 jis z 224 and astm e643 84 standards among others. Erichsen cupping test the sheet metal specimen in the form of strip is inserted into the test cylinder and centralised by locating diagonally. The force applied on the sample is displayed by the gauge.
