Sheet metal testing machine.
Erichsen cupping test for sheet metal.
Erichsen cupping up to 60 kn 80 kn.
Without this testing procedure the series production of hollow bodies made of sheet metal would hardly be possible up to the present day.
Erichsen was the development of a special tool for deep drawing cup test in 1932.
Erichsen testing equipment for sheet metal testing.
Like deep drawing cup test cupping test formability of sheet metal and flc.
Then the depth of the cup is measured and eventually ductility is measure as a function of this depth.
The fraunhofer institute iwu in chemnitz has developed an intelligent quick test for this purpose.
Sheet metal testing machine.
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.
Erickson is considered the inventor of the cupping test and he patented this test method in the early 20th century.
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.
With double olsen up to 60 kn.
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 process.
Erichsen cupping test standards.
Erichsen cupping up to 1 5 mm at 400 n mm.
There are two most commonly used erichsen cupping test standards for reference purposes.
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.
