Erichsen Cupping Test For Sheet Metal

Another coup of mr.

Erichsen cupping test for sheet metal.

Sheet metal testing machine. There are two most commonly used erichsen cupping test standards for reference purposes. For almost 100 years a test method to determine the level of quality of sheet metal exists. The fraunhofer institute iwu in chemnitz has developed an intelligent quick test for this purpose.

Erichsen cupping up to 60 kn 80 kn. Sheet metal testing machine. 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. Erichsen was the development of a special tool for deep drawing cup test in 1932.

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 up to 1 5 mm at 400 n mm. Sheet metal testing machine. Erichsen testing equipment for sheet metal testing.

Then the depth of the cup is measured and eventually ductility is measure as a function of this depth. 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. Like deep drawing cup test cupping test formability of sheet metal and flc. Erichsen cupping test standards.

Erickson is considered the inventor of the cupping test and he patented this test method in the early 20th century.
