Erichsen was the development of a special tool for deep drawing cup test in 1932.
Erichsen cupping test for sheet metal.
The force applied on the sample is displayed by the gauge.
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.
Punching capacity is 600kn and the pre tightening clamping device is with hydraulic servo loading pump for 600kn capacity.
Cupping test is a significant test to assess the ductile properties of the metal.
Sheet metal testing machine model 100.
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.
A visual inspection is done to see if the test material has developed any cracks or deformity.
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.
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.
There are two most commonly used erichsen cupping test 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 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 with erichsen cupping up to 1 5 mm at 400 n mm2.
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.
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.
10 kn in accordance with din en iso 20482 is adjusted using a special regulating valve and the.
Erichsen cupping test standards.
Using intelligent self learning evaluation software it is possible to make a statement on the suitability of the sheet metal within a few minutes.
To punch out round disks from sheet metal strip and then use it to shape it with a drawing.
