Sheet metal testing machine with erichsen cupping up to 1 5 mm at 400 n mm2.
Erichsen cupping test for sheet metal.
The sheet holder force of e g.
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.
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.
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.
Meanwhile the cupping test is adopted by the international standards organization iso and therefore valid worldwide in all industrial applications another coup of mr.
Using intelligent self learning evaluation software it is possible to make a statement on the suitability of the sheet metal within a few minutes.
Punching capacity is 600kn and the pre tightening clamping device is with hydraulic servo loading pump for 600kn capacity.
There are two most commonly used erichsen cupping test standards.
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.
The cupping test for metal sheet thickness range is 0 1mm 5mm max.
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.
Erichsen cupping test as per en iso 20482 astm e 643 gb t 4156.
Universal sheet metal testing machine erichsen cupping deep draw flc up to 200 kn 400 kn.
Then the depth of the cup is measured and eventually ductility is measure as a function of this depth.
Sheet metal testing machine model 100.
It is very simple.
Erichsen cupping test standards.
Remove a piece of sheet metal.
A visual inspection is done to see if the test material has developed any cracks or deformity.
In this test a punching force is applied to the metal sheet of thickness from 0 2mm to 2mm.
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.
