Erichsen Universal Sheet Metal Testing Machine

Model 142-20

With electro-hydraulic drive, max. drawing force 200 kN and for pre-setting the blank holder pressure max. 100 kN, for testing sheets and strips of all types for the properties important for press working: stretch and deep drawing quality using the:

I. Erichsen Cupping Test acc. to EN ISO, EURONORM, DIN, BS, NF, GOST, UNI, UNE
II. Deep Drawing Cup Test in a first and a redrawing operation
III. Deep Drawing Bore Expanding Test acc. to Siebel and Pomp (KWI)
IV. Bore Expanding Tests acc. to ISO 16630
V. Tools for Determination of Forming Limit Curves (FLC) acc. to ISO 12004

 

Key Features

The Testing Machine is driven electro-hydraulically. The test sequence can be controlled automatically or manually, as desired. A programme logic control is used to control the functions of the machine. Drawing force and blankholder force as well as the drawing punch stroke are displayed digitally. The triple-acting hydraulic system in conjunction with the general design results in the following cost saving simplifications:

  • Blanking press in the test head
  • Hydraulic cup ejector
  • Fully-automatic test sequence.

 

Standards

  • ISO 8490
  • ISO 11531
  • ASTM E 643-84
  • DIN 50 101
  • DIN 50 102
  • DIN EN 1669

 

Including

  • blanking press in the test head (max. blanking force 200 kN),
