Erichsen cupping test for sheet metal.

Erichsen cupping test standards. 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. Erickson is considered the inventor of the cupping test and he patented this test method in the early 20th century. Erichsen was the development of a special tool for deep drawing cup test in 1932.

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 up to 60 kn 80 kn. Then the depth of the cup is measured and eventually ductility is measure as a function of this depth. 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 testing equipment for sheet metal testing. Without this testing procedure the series production of hollow bodies made of sheet metal would hardly be possible up to the present day. Erichsen cupping up to 1 5 mm at 400 n mm. For almost 100 years a test method to determine the level of quality of sheet metal exists.

There are two most commonly used erichsen cupping test standards for reference purposes. Sheet metal testing machine. Sheet metal testing machine. Sheet metal testing machine.
