Erichsen Cupping Test For Sheet Metal

Erichsen cupping up to 1 5 mm at 400 n mm.

Erichsen cupping test for sheet metal.

Sheet metal testing machine. For almost 100 years a test method to determine the level of quality of sheet metal exists. 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. Without this testing procedure the series production of hollow bodies made of sheet metal would hardly be possible up to the present day.

Sheet metal testing machine. 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. With double olsen up to 60 kn. The fraunhofer institute iwu in chemnitz has developed an intelligent quick test for this purpose.

Erickson is considered the inventor of the cupping test and he patented this test method in the early 20th century. Like deep drawing cup test cupping test formability of sheet metal and flc. Erichsen cupping up to 60 kn 80 kn. 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. Then the depth of the cup is measured and eventually ductility is measure as a function of this depth. Another coup of mr. There are two most commonly used erichsen cupping test standards for reference purposes.
