Erichsen Cupping Test For Sheet Metal

There are two most commonly used erichsen cupping test standards.

Erichsen cupping test for sheet metal.

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. Sheet metal testing machine with erichsen cupping up to 1 5 mm at 400 n mm2. Universal sheet metal testing machine erichsen cupping deep draw flc up to 200 kn 400 kn. Meanwhile the cupping test is adopted by the international standards organization iso and therefore valid worldwide in all industrial applications another coup of mr.

A visual inspection is done to see if the test material has developed any cracks or deformity. Punching capacity is 600kn and the pre tightening clamping device is with hydraulic servo loading pump for 600kn capacity. The force applied on the sample is displayed by the gauge. Using intelligent self learning evaluation software it is possible to make a statement on the suitability of the sheet metal within a few minutes.

The cupping test for metal sheet thickness range is 0 1mm 5mm max. To punch out round disks from sheet metal strip and then use it to shape it with a drawing. Erichsen cupping test the sheet metal specimen in the form of strip is inserted into the test cylinder and centralised by locating diagonally. Erichsen cupping test as per en iso 20482 astm e 643 gb t 4156.

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 was the development of a special tool for deep drawing cup test in 1932. Then the depth of the cup is measured and eventually ductility is measure as a function of this depth. Remove a piece of sheet metal.

10 kn in accordance with din en iso 20482 is adjusted using a special regulating valve and the. 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. The sheet holder force of e g. Cupping test is a significant test to assess the ductile properties of the metal.

It is very simple. In this test a punching force is applied to the metal sheet of thickness from 0 2mm to 2mm. Erichsen cupping test standards.
