Erichsen Cupping Test For Sheet Metal

Remove a piece of sheet metal.

Erichsen cupping test for sheet metal.

It is very simple. The cupping test for metal sheet thickness range is 0 1mm 5mm max. Sheet metal testing machine with erichsen cupping up to 1 5 mm at 400 n mm2. 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.

The sheet holder force of e g. Cupping test is a significant test to assess the ductile properties of the metal. The force applied on the sample is displayed by the gauge. 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.

There are two most commonly used erichsen cupping test standards. Erichsen cupping test standards. 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. Then the depth of the cup is measured and eventually ductility is measure as a function of this depth.

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. Meanwhile the cupping test is adopted by the international standards organization iso and therefore valid worldwide in all industrial applications another coup of mr. Erichsen cupping test the sheet metal specimen in the form of strip is inserted into the test cylinder and centralised by locating diagonally. A visual inspection is done to see if the test material has developed any cracks or deformity.

To punch out round disks from sheet metal strip and then use it to shape it with a drawing. Sheet metal testing machine model 100. Punching capacity is 600kn and the pre tightening clamping device is with hydraulic servo loading pump for 600kn capacity. In this test a punching force is applied to the metal sheet of thickness from 0 2mm to 2mm.

Erichsen was the development of a special tool for deep drawing cup test in 1932. Using intelligent self learning evaluation software it is possible to make a statement on the suitability of the sheet metal within a few minutes. Universal sheet metal testing machine erichsen cupping deep draw flc up to 200 kn 400 kn.
