Erichsen cupping test standards.
Erichsen cupping test for sheet metal.
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.
It is very simple.
The sheet holder force of e g.
There are two most commonly used erichsen cupping test 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.
Then the depth of the cup is measured and eventually ductility is measure as a function of this depth.
Universal sheet metal testing machine erichsen cupping deep draw flc up to 200 kn 400 kn.
Remove a piece of sheet metal.
Cupping test is a significant test to assess the ductile properties of the metal.
Sheet metal testing machine with erichsen cupping up to 1 5 mm at 400 n mm2.
Punching capacity is 600kn and the pre tightening clamping device is with hydraulic servo loading pump for 600kn capacity.
Meanwhile the cupping test is adopted by the international standards organization iso and therefore valid worldwide in all industrial applications another coup of mr.
The force applied on the sample is displayed by the gauge.
A visual inspection is done to see if the test material has developed any cracks or deformity.
Erichsen cupping test as per en iso 20482 astm e 643 gb t 4156.
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.
Using intelligent self learning evaluation software it is possible to make a statement on the suitability of the sheet metal within a few minutes.
Erichsen cupping test the sheet metal specimen in the form of strip is inserted into the test cylinder and centralised by locating diagonally.
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.
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.
